A New Degree Program Established by NYCU and National Police Agency to Cultivate Future Police Officer Talents in Technology
The rapid development of technologies in recent years has brought more convenience to modern life.
However, it also led to technology crimes, such as cyberattacks, financial fraud, cryptocurrency crimes.
Thus, it causes troubles for police officers in detecting information communication, financial flows, and information security. National Yang Ming Chiao Tung University and National Police Agency worked together to establish the Degree Program of Information and Communication for Technology Crime Investigation in September this year. The purpose is to enhance the information security literacy of police officers and to master the advanced technology of information and communication security.
President Chi-Hung Lin indicated that the Degree Program of Information and Communication for Technology Crime Investigation, founded by the Ministry of Education, will provide 30 additional outstanding police officers for on-the-job training.
These courses integrate the information and communication security expertise offered by Yang Ming Chiao Tung University with the crime investigation practice expertise shared by police officers from Criminal Investigation Police Office to build a systematic education system. Police officers can enhance the knowledge of information and communication security to prevent future information security threats that come along with the convenience of new technology.
Dr. Yong-Sheng Chen, the dean of academic affairs, pointed out that the more convenient technology and the more secure privacy there are, the more challenging to detect cases for investigators. For example, encrypted communication software has a different point-to-point encryption mechanism, which cannot be monitored to obtain the contents of the communication. Besides, nowadays the technology threshold for network anonymity and the cost are lower. Therefore, during the investigation quite often, only springboard IP addresses could be found, which means it could make tracing sources difficult online.
Furthermore, criminal groups in recent years have been using third-party payment for money laundering.
Thus, it also increases the difficulty to trace cash flow.
Police officers specialized in Information security need to understand the ongoing emerging technologies through accumulating experiences through different cases with various cybercrime patterns, and using existing technologies to find breakthrough points on
investigation.
National Yang Ming Chiao Tung University has been working in the field of information security for many years. With 8 faculty members specializing in information security and other more than 60 full-time faculty members in the College of Computer Science, the university has achieved outstanding results in research and industry-academia cooperation. In addition, a Information Security Center was established in recent years with the support of the National Science and Technology Council. In order to grasp the development trend of information and communication security and to establish an application-orientated academic research model, this master program takes place at the college of Computer Science as the core department, and other qualified professors also offer courses for this program, including NYCU School of Law, Medical School, College of Biomedical Science and Engineering. Students can take courses such as programming, computer networks, database systems, machine learning, artificial intelligence, artificial intelligence detection, blockchain, cloud computing, big data, education and training, and financial technology at this master’s program.
In terms of cultivating talents, the program focuses on training crime investigators in which the teachers are the criminal affairs Bureau experts for practical purposes. The purpose is to train students with skills required to deal with security incidents for government, industries, and our society. Eventually, we hope to build a complete technology crime security resources platform with these talents. The Degree Program of Information and Communication for Technology Crime Investigation emphasizes that technology should not be limited to crime investigation, but to accept the fact that crime has been extended to the cyber world in reality. Therefore, promoting general knowledge of technology has become the trend for police officers with different duties. National Yang Ming Chiao Tung University, taking the lead in information security, continues to share research and knowledge with the industry, government, and communities to build a good information security environment in Taiwan.
Through attending this program and investigating issues in real investigation, we aim to find more solutions through more research to meet with the high demand for information and communication security professionals in Taiwan.

4G/5G 多媒體系統
之資安弱點檢測與威脅防護
第四代行動通訊（4G）自技術萌芽之初，
發展至今已逾數十載，憑藉著更快的網速與更大 的網路頻寬，許多過去在 3G 時代所面臨的技術 障礙被一一克服，伴隨 4G 系統的出現，人們的 生活也由「固定式」轉為「行動式」，獲得更大 程度的便利性。科技發展日新月異，轉眼無線通 訊領域也將進入「高速度、低延遲、多連結」的 5G 時代，面對嶄新技術架構一併帶來的未知資 安挑戰，本院資訊工程學系李奇育副教授與其團 隊，開發出一款適用 4G/5G 多媒體系統之資安弱 點檢測模組，用以應對技術更新所產生的資安威 脅。
從技術層面切入討論，已支援現有 4G 語音 服務 VoLTE 和 VoWiFi 的 IP 多媒體子系統（IMS，
IP Multimedia Subsystem）將在未來支援 5G 語音 服務 VoNR （Voice over New Radio）和影像服務 ViNR （Video over New Radio），可見 IMS 系統 是未來 5G 通訊生態系統提供服務的必要元件。
換言之，該系統若存在資安弱點，將對 5G 通訊 造成嚴重資安威脅。李奇育副教授與團隊成員利 用所開發之檢測模組，檢測出三個存在於 IMS 系 統中的重大資安漏洞；同時使用七個廠牌的手機，
在台灣和美國共四個電信商網路中進行實驗，証 實此三個資安漏洞將造成用戶承受包括：秘密通 話拒絕服務攻擊（Denial of Service）、社交工程 攻擊之幽靈通話與來電號碼偽裝攻擊等風險。
特別是前述第一項攻擊威脅一旦出現，將造 成用戶在未收到警示，毫無防備的情況下，無法 撥打或接收任何來電，對於使用者資安影響可見 一斑。開發團隊也於檢測過程中發現，此三個資 安漏洞主要分別發生於 IMS 系統的通話狀態機、
通話管理和號碼驗證，攻擊者可以藉由 VoWiFi 的資安漏洞截取 VoWiFi 應用程式和 IMS 系統之
間的會話連線，偽造對話啟動協定 SIP 封包，對 IMS 系統的三個資安漏洞進行攻擊。為了檢視此 資安威脅可能帶來的最大損害，開發團隊設計了 具自動調適的拒絕服務攻擊，實驗顯示，此攻擊 對受害用戶的有效攻擊時間竟可達 99%，再次凸 顯此漏洞急需解決應對之法，否則將產生極大的 資安疑慮。
運用 AI 技術，開發團隊還發現現有 4G/5G 電信網路的另一個資安漏洞——通話資訊洩漏，
它可被利用來對目標用戶的電話進行遠端偵測。
也就是在用戶毫不知情的情況下，攻擊者僅需知 道用戶的電話號碼，便可判斷其是否可為攻擊目 標。為了應對上述潛在威脅，李奇育副教授與開 發團隊除了將檢測結果回報給 GSMA 行動網路協 會，同時提出系列解決方案，包含應用層資料來 源認證、延遲通話資源綁定技術和通話管理限制 分離；並使用開源軟體 OpenIMSCore 證明，該解 決方案在不影響系統效能前提下之實踐可行性。
一併搭配應用 AI 發展出的「來電號碼偽裝攻擊 之防護檢測技術」，檢測來電通話是否為號碼偽 裝攻擊，為 4G/5G 技術下新生之資安危脅提供對 應參考解方。
隨著 5G 時代來臨，相關技術不僅在全球經 濟發展中扮演關鍵角色，其於各行業、領域的應 用範圍和規模也將逐步擴大，高速穩定的通訊技 術一旦普及，潛在的資安威脅將讓人難以忽視。
李奇育副教授與團隊成員所研發之資安弱點檢測 與威脅防護技術，將有助於行動通訊技術標準
（如 3GPP 和 GSMA）、國內外電信商、設備商 和手機製造商，檢測和修補存在於多媒體服務應 用程式和系統的資安風險。如此卓越貢獻，也將 造福全球行動通訊技術相關產業，期待此項技術 未來於運作系統中的實際應用！

4G/5G Multimedia Application Security
Vulnerability Detection and Threat Protection
The fourth-generation mobile communication (4G) has been developed for more than decades since the mobile communication technology debuted. With faster network speed and larger bandwidth, many technical obstacles of 3G mobile network have been overcome. Moreover, the emergence of 4G has changed people's lives from "fixed" to "mobile" so that people have gained a higher degree of convenience.
With the rapid development of technology in modern life, the wireless communication network is driving towards the 5G era, promising "high speed, low latency and massive connections". Facing the unknown challenges in information security associated with the new technical framework, Associate Professor Chi-Yu Li of the Department of Computer Science and his team have developed an information security vulnerability detection module for 4G/5G multimedia systems to defend against information security threats introduced by technology revolution.
From a technical perspective, the IP Multimedia Subsystem (IMS, IP Multimedia Subsystem), which supports the existing 4G voice services VoLTE and VoWiFi, will support 5G voice service VoNR (Voice over New Radio) and video service ViNR (Video over New Radio) in the future. The IMS system is definitely a key component for the future 5G communication ecosystem. In other words, if some information security weaknesses exist in the IMS system, it will pose a serious threat to 5G communications.
Professor Li and his team used the developed detection module to identify three major information security vulnerabilities in the IMS system. In the experiment, they simultaneously used seven brands of mobile phones in four telecom networks both in Taiwan and in the United States. Finally, they have confirmed that these three security vulnerabilities can put a user's plan in jeopardy, such as secret call denial of service attacks (Denial of Service), social engineering attacks (ghost calls), and caller number spoofing attacks.
In particular, once the first attack threat mentioned above occurs, users are unable to make or receive any calls without warnings and precautions, thereby greatly affecting user experience with information security. During the detection process, the team also discovered that these three information security vulnerabilities are mostly found in the call state machine, call management and number verification in the IMS system. Through the security vulnerabilities of VoWiFi, attackers can intercept the connection session between the VoWiFi application and the IMS system, as well as create fake Session Initiation
Protocol (SIP) packets, thereby attacking the three security vulnerabilities of the IMS system. In order to examine the maximal potential damage caused by the information security threat, the team designed a self-adaptive denial-of-service (DOS) attack. Their experiments show that the effective attack time of this attack on victims can reach 99%, which once again highlights that this vulnerability needs to be solved in no time, otherwise it will cause critical security concerns.
Meanwhile, the team uses AI technology to find another information security loophole in the existing 4G/5G telecommunications network: call information leakage, which can be used to remotely identify the target user's phone. In other words, an attacker can target the victim by the phone number without the knowledge or consent of the user. In order to deal with the above potential threat, Professor Li and his team not only reported the results to The Global System for Mobile Communications Association (GSMA), but also proposed a series of solutions, including application layer data source authentication, delayed call resource binding, and call control isolation. In addition, the team used the open-source software OpenIMSCore to demonstrate the practical feasibility of the solution while maintaining system performance. Combining with "Caller Number Masquerade Attack Protection Detection Technology", which checks if the incoming request is a request forgery attack by AI technology, this package provides a corresponding solution for the emerging information security threat under 4G/5G technology.
With the advent of the 5G era, related technologies not only play a key role in the development of the global economy, but also gradually expand the application scope and scale to diverse industries and fields.
However, once the stable high-speed communication technology becomes popular, the following potential threat to information security would be too severe to ignore. The information security vulnerability detection and threat protection technology developed by Associate Professor Li and his team will assist mobile communication standards organizations(3GPP and GSMA), domestic and foreign telecom carriers, equipment manufacturers, as well as mobile phone manufacturers to identify and reduce application- level and system-related security risks of multimedia services. Such an outstanding contribution will also benefit the global mobile communication industry.
We look forward to the practical applications of this technology in the system in the future.

隨著網際網路普及與各項資訊技術發展革 新，國內外許多產業都乘上了資訊化的浪潮，迎 向「數位經濟」新時代。從資訊化的作業流程，
到虛擬化的產品服務、數位化的金融交易，以及 電子化的商業行為，系列新型態的生產、消費模 式轉變，不僅為生活帶來高度的便利性，同時也 成為帶動產業創新、優化產業結構的原動力。本 院資工系的彭文志教授與其團隊，順應數位經濟 發展趨勢，開發出一款「可剖析顧客行為模式以 提供個人化自動服務」之廣告標題生成技術，讓 商家在精準投放廣告的同時，高效促進顧客消費 行為之實踐。
「數位經濟」之具體應用形式之一，即是將 大數據與人工智慧技術運用於既有的金融消費模 式上，達到預測消費者消費行為之目的。彭文志 教授於受訪時提到，早期金融產業如銀行與各商 家在選擇行銷手法時，多半只針對具備會員身分 的用戶進行廣告投放。但近年來，運用統計與機 率的方式，銀行逐步能透過分析報告了解其客群 的消費模式；此外，隨著資料的大量累積與演算 法不斷地進步，若配合機器學習與深度學習等相 關技術，還能做到「對單一消費者進行消費行為 分析」這般細膩且精準的操作。如此一來，商家 便能針對消費者進行客製化的廣告投放，而個人 化 EDM（Electronic Direct Mail）就是其中一種實 踐手法，同時也是彭文志教授與其團隊所開發技 術的應用範疇。
EDM 行銷主要藉由發送電子郵件達到通知、
促銷、行銷等目的，儘管電子郵件技術問世至今
已逾數十載，該行銷手法仍未被新興的社群媒體 所取代，主要可歸功於其技術成熟、成本穩定的 特性。彭文志教授團隊所開發之技術內容主要包 含「建立顧客行為預測與推薦系統」與「協同吸 引力文章標題產生」兩大方向，前者透過消費資 料庫為顧客建檔，發掘行為特徵，強化行銷策略 與消費行為分析的連結；後者藉由解析顧客的社 群點擊紀錄與消費關聯，剖析「顧客—意圖—金 融產品」三者錯綜複雜之關係，進而生成個人化 標題，作為 EDM 行銷用途。
運用團隊開發技術進行個人化廣告投放，一 方面能讓商家針對特定消費族群投其所好，提供 最合適之廣告內容；另一方面，消費者也能精準 獲得其所需的商品通知，不受多餘資訊打擾，進 而提升簽帳比例與消費行為轉換率。此外，於廣 告持續投遞過程中，系統會透過檢視消費者與該 則廣告的互動情形，作為人工智慧模型調整的依 據，透過不斷地循環、學習產製出最精準、客製 化的 EDM 內容。
目前彭文志教授團隊已透過與 KKDAY 及玉 山銀行的合作，驗證該技術之產業應用性，搭配 前述兩者所提供之時空資料庫、金融語意及圖像 資料庫、社群網路身分資料庫，統整使用者瀏覽、
消費紀錄等數據，分析出客戶喜好、行為模式等 特徵，使得精確且個人化的 EDM 內容投放成為 可能，同時大幅提升消費行為轉換率，一舉為供 需雙方營造雙贏局面。本技術之開發團隊能將商 業金融與資訊科技雙領域之學識經驗結合，創造 可能並加以應用，實為跨域合作之成功典範！

Predicting Consumer Behavior
and Generating Personalized Titles with Data Analytics
With the rapid development of information technology and popularization of the world-wide Internet, many industries, both domestically and abroad, have been riding the wave of informatization and embracing a new era of digital economy. Including information technology workflow, product service virtualization, digital transactions, and electronic business, the transformation of production and consumption pattern not only brings the next level of convenience, but also becomes the driving force of industrial innovation and industrial structure optimization. Following the development trend of the digital economy, Professor Wen-Chih Peng and his team of the Department of Computer Science at NYCU, developed advertising headlines generation technology, which can analyze customer behavior patterns to design and produce customized automated services, to help merchants not only improve the effectiveness of advertising, but also promote consumption efficiently.
One of the forms of work in the Digital Economy is to apply big data and artificial intelligence technology to the existing consumer financial patterns to accurately predict consumer behavior. In the interview, Professor Peng said that financial industries such as banks and merchants in the past only targeted users with membership status for advertising.
Nowadays, statistics and probability methods can help banks with analytics to deeply recognize the consumption patterns of their customers. In addition, with the accumulation of large amounts of data and continuous improvement of algorithms, it is possible to achieve precise operation as "analyzing the individual consumer behavior" when we combine technologies such as machine learning and deep learning. In this way, merchants can carry out custom advertising to their target customers. One of the practices is Personalized EDM (Electronic Direct Mail), which is also the application field of the technology developed by Professor Peng and his team.
EDM marketing is a type of marketing that sends email to generate more leads, build relationships, and increase sales. Although being used for over decades, email marketing is not replaced by the emerging
social media due to the mature technology and easy- to-estimate cost. The applications developed by Professor Peng and his team include "A Customer Behavior Prediction and Recommendation System"
and "Collaborative Eye-Catching Title Generator". The former builds customer profile database to discover behavioral traits to strengthen the link between marketing strategy and consumer behavior analysis, while the latter analyzes the intricate relationship between customer, intention, and financial product by establishing the relation between customers’ ad clicks on social media and their purchase, thereby creating a custom title for EDM Marketing campaign.
While using the technology developed by the team to carry out custom advertising to their target customers, on the one hand, merchants can target their marketing messages to specific individuals; on the other hand, consumers can receive accurate product notification without redundant information to increase consumer conversion rate and spending. In addition, during continuous advertising, the system will keep adjusting the artificial intelligence model according to the interaction between consumers and advertisers, thereby creating the most accurate and customized EDM content.
At present, Professor Peng and his team have verified the industrial applicability of this technology through the collaboration with KKDAY and E.SUN BANK.
Combining with spatiotemporal database, financial semantics and image database, as well as social network identity database provided by the above two companies, the team consolidates user browsing and consumption records to analyze customer preferences and behavior patterns and make accurate and customized EDM content accordingly, thereby greatly increasing customer conversion rate and creating win-win situations for both customers and suppliers.
Professor Peng and his team integrate the knowledge and experiences of business finance and information technology to innovate with new applications, which successfully builds a model of cross-domain collaboration!

演講內容充分激發陳老師的興趣與熱忱，他立刻主 動寫信向黃教授詢問是否可以參與研究專案。在獲 得肯定答覆後，陳奕廷老師便以新成員的身分加入 研究團隊，協助專題計畫進行。
「我覺得這是一個很重要的契機，讓我開 始對『研究』這件事情有想法，知道自己在做什 麼。」初次的研究經驗累積，與其所帶來之成就 感，為陳奕廷老師在探索自我、了解自身未來規 劃等面向帶來極大的幫助。該次的專題產製經驗 也讓陳老師下定決心，將原先的「出國交換探索、
考慮攻讀碩士」等階段性目標延伸規劃，並修訂
「申請博士班」為最終目標。儘管摸清了努力方 向，後續也順利申請上博士班，陳老師卻面臨了 多數國際學生都會遇到的難題——高額消費與學
費所帶來的負擔，在沒有金援的情況下，頂著極 大的金錢壓力度過第一個學期。
為何研究？藏不住的熱忱會告訴你
談及「研究動力」與「贊助金援」取捨的兩 難，陳奕廷老師回想起在求學第二學期時，雖成 功得到獎助學金，但研究主題卻與自身興趣有所 出入，在深入探索時總會少了幾分熱忱，這樣的 困境直到博士班倒數第二年，修習「電腦視覺」
課程之後才有所改善。好不容易找尋到極具探索 熱忱之研究領域，但考量到畢業時限在即，面對
「等待機會從事相關研究」或「進入職場尋找相 關工作」的二選一難題，陳老師選擇了前者，在 大學同學牽線下，加入了美國加州大學美西德分 校楊明玄教授的電腦視覺研究團隊。憶起當時自 己在自薦信中提到「我不管有沒有獎助金，我就 是要去做！」陳老師認為，或許正因毫不掩飾嶄 露「真的想做」的熱忱與決心，才有機會打動楊 教授，獲得貴人相助，實踐所學，繳出兩項研究 計畫成果。
緊接著，在多次研究與實習經驗累積過程 中，陳奕廷老師逐步摸索出自身投身研究的理由 與目標。在美國本田研究所時，陳老師從先進駕 駛系統專案中意識到，車禍事故所引發之社會問 題有迫切解決的需求，而自身所學之實踐正是解 方之一；「電腦視覺」不單可當作研究興趣，其 延伸應用如智慧駕駛系統、輔助機器人等技術更 可為交通安全、居家照護等社會議題做出貢獻。
「運用所學，為有需要的人提供協助，改變並解 決現存之問題，或許正是我一直以來追尋的研究 目標與意義。」這是陳老師面對「為何研究」的 問題思考，透過親身經歷所得出，簡單卻富含深 意的答案。
於訪談末段，陳奕廷老師分享了工作最後一 年帶實習生的特別經驗。擔任 mentor 期間，陳 老師能充分感受到實習生對研究的迷茫好似當年 的自己；他認為，若有人能在此時以過來人的身 分，提供引導並給予自信，對於研究新鮮人定有 極大助益，這也正是陳老師選擇投身教職的原因 之一。結合各項經歷，陳老師以自身體悟勉勵同 學們：「主動積極去追尋自己興趣的同時，做自 己熱愛且能夠讓世界變得更好的事！」期待莘莘 學子們能充分探索自我，投注熱忱於所學，貢獻 並造福社會！
We are very honored to invite Dr. Yi-Ting Chen, an assistant professor of the College of Computer Science who specializes in intelligent driving systems, computer vision, artificial intelligence, and machine learning in this interview. We hope to share Dr. Chen’s diversified study and career experiences to students of our college for career planning as a great reference. From having doubts to think about whether to pursue a research career, to the experience of job application and his teaching philosophy, Dr. Yi-Ting Chen shared his ups and downs in this journey.
It is normal to feel confused, but don’t forget to seize your opportunity
When majoring in Electrical Engineering in his senior year of NCTU, Dr. Chen had already started thinking about his future. Considering the time taken to prepare for application documents and examinations to study abroad, he decided to apply for a short- term exchange program at the University of Illinois at Urbana-Champaign. Through this opportunity, he wanted to see if he was able to fit in and can further pursue master’s and doctoral degrees abroad in the future. Just before he left for his exchange program, he recalled that coincidentally Prof. Thomas S. Huang, a professor at Illinois at Urbana Champaign was invited to give a lecture at NCTU. Dr. Huang was one of the leading figures in pattern recognition, computer vision, and human computer interaction. Dr. Chen was deeply inspired by Dr. Huang’s lecture so he immediately wrote to Professor Huang to ask if he could participate in the research project. After receiving a positive answer, Dr. Yi- Ting Chen joined the research team in the project team directed by Dr. Huang. “I think this was a turning point for me to start to think about the meaning of research and what I was doing.” Not only gaining a sense of self- achievement from research experiences, conducting research also helped him to explore and plan for his future. This experience gained from the research project also made Dr. Chen determined to extend his plan from a short-term exchange and master’s degree to a doctoral program application as his final goal. Although Dr. Chen made up his mind and successfully enrolled in the doctoral program, he soon faced a challenge that most international students encountered-the burden of high living costs and expensive tuition fees. He had a rough first semester under enormous pressure without financial support in his doctoral study.
What is the purpose of research? Your passion will answer you
When it comes to the dilemma of choosing between the passion to conduct research or receiving an assistantship, Dr. Chen shared his memory during his second semester of doctoral study. Although he did
successfully receive an assistantship, he was not very motivated in the research topic he was conducting. This situation did not improve until the second last year of his doctoral study when taking the course, Computer Vision, in which he found a passion for research. Just not long after he discovered his passion, Dr. Chen soon faced another challenge, which was that it was about time for him to graduate from doctoral study. He needed to decide whether to keep waiting for an opportunity to do research that he was very interested in or enter the job market in a related field. In the end, he chose the former option and joined Prof. Ming-Hsuan Yang’s computer vision research team at the University of California at Merced. In his cover letter to apply for a position at Dr. Yang’s lab, he wrote “I don’t care if I have an assistantship or not, I just want to do it!”.
Perhaps the reason why he was recruited by Dr. Yang and earned this opportunity was because of his strong determination. With this firm and positive attitude, Dr.
Chen was able to publish two papers while working in Dr. Yang’s research team.
Dr. Yi-Ting Chen gradually found the reasons and goals for his devotion to research from many research and internship experiences. When working at the Honda Research Institute USA, Dr. Chen realized he could put his expertise into solving real problems. For instance, he found that there was an urgent need to solve problems caused by car accidents when exploring advanced driver assist system projects. “Computer Vision” could be more than a research interest, moreover, it can be applied in intelligent driving systems, and assistive robots to contribute to traffic safety and home-care services. “Using what I learned and providing assistance to people in need to solve existing problems is my goal behind my passion in research. This is a simple yet meaningful answer to the question of "what is the purpose of research", and Dr. Chen conveyed the messages through his personal experiences.
At the end of the interview, Dr. Chen shared his experience when leading interns in the final year in Honda Research Institute USA. When guiding interns as a mentor, he felt that those interns’ circumstances were very similar to him back then, such as feeling confused about their future and research. He believes that if someone could provide guidance based on their perspective as an experienced researcher, it would be very helpful for younger generations. It was also the reason why he devoted himself to teaching at the Department of Computer Science at NYCU. Now He often encourages his students to “actively pursue their passion and do what they love to make the world a better place.” He hopes that students can explore and devote themselves fully to their studies and give what they have to this society.

Futuristic Technologies: NYCU Alumni Day
In early April this year, with the festive atmosphere of the first " NYCU Alumni Day" after Yang Ming Chiao Tung University was merged, the Department of Computer Science launched the "Futuristic Technologies Series Activities" during the event, and jointly unveiled the
"Taiwan Computer Information Development Center".
At the same time, the Outstanding Alumni Award were awarded. All friends and alumni were invited to join the great feast. The activities not only received enthusiastic response from "Computer Science guy", but also attracted both media friends and students who are interested in related fields to attend.
In the Alumni awards ceremony, the seniors who are outstanding in various fields "came back home" and proactively participated in this event to share their precious academic and career experience with young students. Following the tradition of “back home”, they hope to practice the "NYCU guys support each other"
Spirit and transform their experiences into nutrients for the growth of young students. Shun-Shii Lin (‘70), who was awarded the Outstanding Alumni award, recalled the process of embracing teaching as a career. Since he is passionate about puzzle games such as chess and cards, he integrated his enthusiasm with the research.
Applying what he has learned, he and his students have developed a program which is ranked among the best in the world in chess and card games. The calculation efficiency can handle hundreds of millions of game states per second. The applications of core technology amazingly span from East to West games, such as Mahjong, bridge, and Othello. Lin, driven by his own passions, keeps on seeking further innovations and changes in AI fields. Such spirit is truly a role model for all students.
Wei-Chung Hwang (‘80) also shared his unique observation while developing software: "Under this new trend of information technology, it is necessary for everyone in various fields to collaborate with each other;
in other words, it is impossible to develop a perfect product by a team with single expertise. No matter whether it is in the information field, the humanities and social sciences field, or the medical field, cooperating with each other in various fields and exerting their strengths is mandatory to create better products.”
Huang hoped that the future talents will accumulate more experience in cross-domain cooperation, build a cooperation ecosystem with talents of various expertise, and bring forward the information technology industry.
We believe that the experience sharing of outstanding alumni will benefit the faculty and students a lot.
Congratulations again to the winners of this award,
Rong-Shy Lin, Shun-Shii Lin, Jie-Cheng Wang, Wei- Chung Hwang, Ju-Kau Chen, Mike Jiang, and Yenwen Feng.
Apart from the Outstanding Alumni Award Ceremony, another main focus event is the Futuristic Technologies speech given by Dr. Liang Bor-Sung, Senior Director of MediaTek, and Frank Lin (‘81), Director of TSMC IT Enterprise System Integration Department. Dr. Liang started from three paradigm shifts of Computing Platform. Through the technological development process in chronological order, he guided the audience, from the shallower to the deeper, to the theme of
"Future Computing Trend: From Integrated Circuits to Artificial Intelligence as well as the Metaverse".
Responding to people's concerns about "whether AI will surpass the human brain", Dr. Liang took specific examples and diagrams to point out that " the current capability of artificial intelligence is far worse than that of the human brain." He also encouraged the faculty and students: The existing primitive level of technology and the bottleneck of computing performance may become the target of research breakthroughs and motivation in academia and industry. We are currently in a stage as if
"while observing birds, human beings want to learn to fly" and the progress in the fields advances sluggishly;
however, in an era of rapid technological development, some of you may be the developers of "the principle of efficient flight" in the near future. At that time, the depth and breadth of artificial intelligence applications will exceed the scope of our current knowledge.
In the second half of the speech, Frank Lin, a director at TSMC, cut into the current state of the industry and raised a question for everyone: how to achieve stronger computing with lower energy consumption. This statement echoes Dr. Liang's speech. Referring to the digital transformation challenges all enterprises face, Lin pointed out "business value thinking, mindset of product associated with software, and clear blueprint and vision"
are the three key factors to success. Combining with the support of relevant business units, it will be an effective
"good transition". "No one can assure whether we are doing the right things; however, I am sure that we are on the right track and will continue our best endeavors." Lin ended the speech with an optimistic attitude towards the challenges of transformation. Once again, we thank Dr. Liang Bor-Sung and Mr. Frank Lin for such wonderful sharing, as well as the distinguished guests for their enthusiastic response, which brought this event to a perfect conclusion. Looking forward to seeing you again next year!

Rong-Shy Lin, an Outstanding Alumnus:
Altruism and Mutual Advantage
The first list of outstanding alumni after the merger was announced at the end of last year, which marks a milestone towards creating a great university. In addition to the leaders in the medical and public health field, who protect our health at the forefront of epidemic prevention, the list included many talents in the field of information and telecommunications, who have laid the foundation of Taiwan's existing telecommunication infrastructure and established a global presence in the future. Among them, Dr.
Rong-Shy Lin, Senior Executive Vice President (Chief Technology Officer) of Chunghwa Telecom, graduated from the Department of Computer Science at NCTU in 1976. He has been deeply involved in the field of information and telecommunications over the past 30 years and spared no effort in creating mobile 5G and broadband services in Taiwan.
Dr. Lin received his doctorate in computer science at NCTU. Specializing in application development and network and data communication deployment, he has held important positions including general manager of Chunghwa Telecom Data Communication and president of Chunghwa Telecom Laboratories. He is also a technology pioneer with knowledge and industry experience. In the early days of 5G technology, Dr.
Lin combined his thorough industry observation with the knowledge and experience accumulated over the years to advance the strategic arrangement for the era of intelligent networking where "everything can be connected to the Internet." While realizing the positioning of the telecommunications industry in the new business paradigm, Dr. Lin identified its characteristic of "intermediary," which has the greatest opportunity to link both users and application services.
Once the goal was confirmed, a series of large-scale projects, such as smart transportation, smart security, and smart energy, immediately kicked off.
Besides exerting the expertise in the workplace, s u p e r v i s i n g t h e c o n s t r u c t i o n o f m o b i l e 5 G infrastructure, creating a mobile broadband smart generation, and driving the flourishing activity of the Internet society, Dr. Lin fulfills his social responsibilities, which he has long been promoting the establishment of public safety and emergency communications for disaster management and risk reduction. On the other hand, Dr. Lin kept the spirit of “drinking water while thinking of the source” to actively provide resources and assistance to NYCU in order to enhance the
international competitiveness of NYCU talents through industry-academic collaboration. In the "Industry- University Alliance Project," which was formed in 2013, Dr. Lin played a vital role in the industry- academia cooperation with Chunghwa Telecom. In addition, he has assisted NYCU in building the testbed of a leading-edge telecommunication network, which significantly benefits the research in the fields such as advanced wireless broadband and free5GC (the world's first open-source 5G core network implementation complying with the 3GPP R15).
Over the University Day celebration week, as an extraordinary alumnus of NYCU and an alumnus of the Department of Computer Science, Dr. Lin attended the ceremony on campus for the outstanding alumni award. At the same time, he took this opportunity to share his experience in team management and affairs coordination with faculty and students. Recalling the impact of the first job experience, Dr. Lin pointed out the importance of establishing the concept of "altruism and mutual advantage." Compared with the personal academic achievement people pursue in school, cooperation in the workplace is unavoidable. In other words, altruism is literally equivalent to self-interest when people are on the same team. And the key factor of efficient and productive teamwork is boosting altruistic behavior to generate positive momentum.
And not only that, but the "heterogeneity" of members would also be a main factor of consideration while forming a team. For example, diverse opinions/
viewpoints and compatibility adjustment with complementary personalities are both benefits of high heterogeneity.
At the end of the sharing session, Dr. Lin encouraged the students, "Keep aware of your real need: doing right things or doing things right." He remarked that macroscopic patterns would be the key to making better decisions. The success of a project heavily relies on finding the right problem and fixing it. In addition to laying out the key technologies and services for his company's transformation and growth, as well as leading his team to establish an agile product development process so as to promptly satisfy market requirements, our outstanding alumnus Lin distilled his career experience and shared with the students without reserve, which indeed fulfilled the spiritual model of "NYCU guys support each other."
Science Column 科普軼聞
最近我到高雄市的國立科學工藝博物館演 講，順便參觀其珍貴館藏，無意間看到中華電信 的骨董傳真機 TYPE LDI-3 FACSIMILE，頗有親切 感。科工館的解說：「傳真機為結合光學、電子、
精密機械及通訊等多項技術的事務機器。由於網 際網路通訊盛行，傳真機市場逐步衰退，且單一 功能傳真機已不符需求，故廠商推出結合傳真、
掃描、影印及列印等多功能傳真機來因應市場變 化。」今日傳真機被當成不符需求的事務機器，
其實它可是 1940 年代的劃時代創新。
數位分身是今日的熱門話題，而傳真機應 該是最早期的遠距數位分身產生器。傳真機的前 世可歸功於倫傑 (Richard Ranger) 發明的無線傳 真 (wireless photoradiogram 或 transoceanic radio facsimile)。這部無線傳真機由紐約傳送第一張 照片到倫敦，照片是時任美國總統柯立芝 (John Coolidge) 的玉照。
倫傑於 1930 年成立 Rangertone 公司，位於 紐澤西州的紐瓦克 (Newark)，這家公司在三號公 路附近，我曾拜訪過。倫傑一生多采多姿，有許 多發明，還得過奧斯卡金像獎。直到今日，無 線傳真仍然用於傳送氣象圖及資訊。1924 年，
AT&T 的艾維斯 (Herbert Ives) 完成第一張彩色傳 真。艾維斯是個特異獨行俠，多次公開表示反對 愛因斯坦的相對論。
1925 年 貝 爾 實 驗 室 採 用 真 空 管 技 術 和 光 電管技術研製出了實用型的傳真機。1947 年慕 維 廉 (Alexander Muirhead) 發 明 現 代 的 傳 真 機；
1960 年代，美國陸軍首次以衛星傳送照片到波 多黎各 (Puerto Rico)。早期的傳真機採用阿摩尼 亞水來作顯影液，到後期才出現用特別熱感紙的 傳真機。
中華電信總公司陳列一部早期的傳真機，這 部日本 Toho Denki 製造的傳真機於 1968 年出品，
將客戶手寫之電報稿，原樣地發送或接收。1970 年代中期，因傳真機成本大幅下降，遂普遍被採 用，尤其是數位傳真機在日本率先流行，很快取 代電傳打字機 (teletypewriter)。其主因是，在那 個年代，以打字機敲打日文很不方便，遠不如傳 真機的掃描快速。傳真電報稿不必先譯成電碼再 傳送，而可直接送真跡到對方客戶端。
1980 年後，傳真機已遍佈全世界。1985 年，
麥格努斯基 (Hank Magnuski) 製作第一張電腦傳真 擴充卡 GammaFax，完成第一部電腦傳真機。現 在的傳真機大多數都依此原理，採用噴墨或雷射 列印。今日傳真的服務已漸漸被網路上的服務取 代，不過傳真仍有優點，例如它不像網路產品那 樣容易被入侵或中毒。因此一些機密文件，仍然 依賴傳真機的傳送。
The Forerunner of Digital Cloning:
Fax Machine
Recently I gave a speech at the National Science and Technology Museum in Kaohsiung City, and stopped by to enjoy the precious collection. It was quite familiar to me when I saw Chunghwa Telecom's antique fax machine, TYPE LDI-3 FACSIMILE, by accident. The National Science and Technology Museum explanatory text described, “Fax machines are business machines that integrate optics, electronic, precision machinery, and communications. The fax machine market declines gradually due to the prevalence of internet use. At the same time, single-function fax machines cannot meet the end users’ expectation so that vendors promote multi-function fax machines, which offer faxing, scanning, photocopying and printing in one box, in response to market changes.” Although fax machine today is regarded as a business machine that does not meet the requirements, it was in fact an epoch-making innovation in the 1940s.
While digital clones are a hot topic today, fax machines should be the earliest remote digital clone generator. The forerunner of current fax machines was wireless photoradiogram or transoceanic radio facsimile invented by Richard Ranger. The wireless fax machine sent the first photo, which was a photograph of President John Calvin Coolidge, from New York to London.
Ranger formed a company, Rangertone, Inc., in Newark, New Jersey in 1930. I have visited that company near Highway 3. Ranger lives a colorful life.
He has many inventions, and won an Academy Award.
Until today, wireless faxing is still used to transmit weather maps and information. In 1924, Herbert Ives of AT&T developed the first color facsimile. Ives is a loner and he has publicly spoken out against Einstein's theory of relativity on several occasions.
In 1925, Bell Labs developed a practical fax machine using vacuum tubes and photocells. In 1947, Alexander Muirhead invented the modern fax machine; in the 1960s, the US Army first sent images to Puerto Rico by satellite. The early fax machines utilized ammonia solution as a developer, and in the later period, fax machines using special thermal paper became available.
Chunghwa Telecom Corporation exhibits an early fax machine. This facsimile machine Toho Denki, manufactured in Japan in 1968, sends or receives the customer’s handwritten telegram as it is. In the mid- 1970s, the cost of fax machines reduced sharply, so they were widely accepted. In particular, digital fax machines became popular in Japan and soon replaced teletypewriters. In those days, typing Japanese with a typewriter was inconvenient, which was far less efficient than scanning hand-written documents with a fax machine. Fax telegram drafts did not need to be translated into codes before transmission, but were directly sent to the peer.
After 1980, fax machines were used around the world. In 1985, Hank Magnuski produced the first computer fax add-on card, called GammaFax, and invented the first computer fax machine. Most of today's fax machines follow Magnuski’s design concept, either using inkjet or laser printing. Today's fax service has been gradually substituted by the service on the Internet; however, fax still possesses some advantages since it is not as easy to be hacked or poisoned as Internet products. Therefore, some confidential documents still rely on the transmission of fax machines.
