| Outline of Final Research Achievements |
We proposed various types of watermarking methods in accordance with the evaluation criteria of the watermarking methods, and evaluated them. The spread spectrum watermarking method could achieve good performance by using suitable scheduling. Against clipping attack to stego-images, we considered two methods. One is the method using error correcting codes with a synchronization code, and the other is the method using feature extraction without the synchronization code. The former could counter the clipping attack by using LDPC and concatenated codes. The latter could have potential ability to counter the scaling and rotation attacks.
