| Outline of Final Research Achievements |
In the case of an existing copyright protection scheme, owner of copyright register one’s copyright information in certificate authority. And certificate authority only validates the evidence of copyright information of a doubtful content. The doubtful content must be searched by owner of copyright. In this research, pre-search method, which picks out the doubtful image content from Internet, was proposed. This pre-search method preform high-speed response and adapt to any case by use of feature quantity such as Local Bit Pattern(LPB) histogram. Also average attack, which is one of collusion attack, become forbidding in recent years. In this research, watermarking scheme by geometry translation was proposed in order to inhibit average attack.
