Future works…

In the future, we aim to add some features to the proposed methods, as follows:

1. Try to add the feature of fault tolerance to the turnover style and two-level style.

2. Try to add the ability of progressive viewing, when the number of collected shares reach a predefined thresholds;

3. Try to increase the capacity of the hidden data disclosed in Level 2 of the two-level sharing.
