Evaluation of watermarking method using SIFT features on the basis of IHC ver.5

Abstract (in Japanese) (See Japanese page) 
(in English) We propose a watermarking method using SIFT features which have both scale and rotation invariances, and evaluate our method in accordance with the information hiding criteria (IHC) ver. 5. The IHC ver. 5 aims to be applied for commercial applications of the contents industry. It is defined as the evaluation criteria against several possible attacks; geometric attacks, e.g., scaling, rotation, and clipping, and JPEG compression. In our method, we use local feature regions located around the SIFT features which are robust for scaling and rotation, and we embed watermarks in normalized local feature regions. We also introduce two error-correction techniques; a weighted majority voting (WMV) and a low-density parity-check (LDPC) code. When a stego-image is attacked by scaling or rotation, the image is spatially distorted. The WMV and LDPC can correct errors of extracted watermarks in the distorted stego-image. On the other hand, it is not easy to detect rotated local feature regions. Therefore, the regions are searched for by brute force. We evaluated the proposed method in accordance with IHC ver. 5. Our method can achieve the highest tolerance category for scaling and rotation attacks.
