| Outline of Final Research Achievements |
In order to develop the information hiding method which has high image-quality and robustness against image processing, we proposed two methods. One is a method using invariant features. Watermarks are embedded into embedding area around feature points which are robust against geometric transform. The proposed method could reduce errors in the watermarks by improvement of embedding technique and error correcting codes. The other is a neural network. The proposed network has a rotation-attack simulator inside and can learn robust stego-images. As a result, we could construct robust embedder and extractor networks against the rotation attack.
