| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes an encryption method to enable hierarchical access controls for JPEG 2000 codestreams. The proposed method provides access control to images of various quality levels that may be different from the quality at encoding, though it uses a single codestream and a single managed key (masterkey). Only one key generated from the masterkey is delivered to a user authorized to access a reserved quality image. This method also takes account into attacks that access superior-quality images by users' collusion. Some conventional methods serve the above features, but those keys are much longer than the keys of the proposed method. The proposed method uses the key whose length does not depend on the hierarchy levels of JP2 codestream by introducing sub-resistance to collusion attacks. |
