| Abstract(in English) | This paper proposes hierarchical-and-region-selective secret sharing methods for image data in order to improve usability of the conventional secret sharing schemes using JPEG 2000 code-steam syntax. In the conventional (k, n)-threshold secret sharing scheme, secret data is reconstructed only if more shares are gathered and combined than a pre-decided number, k. Furthermore, the conventional methods are not able to reconstructed the secret data partially and hierarchically. Though large k makes a strong security feature, it creates problems with the handling of the many shares required to reconstruct the original data. Therefore, in order to improve usability, we propose two new secret sharing methods using JPEG 2000's hierarchical-and-region-selective image representation. This paper shows the feasibility and efficiency of the proposed methods by computer simulations. |
