Abstract(in English) | An important issue of fragile watermarking for image is to locate and recover the tampered pixels individually. This issue is resolved for concentrated tampering (i.e., a significantly small error probability is achieved in both pixel-wise localization and recovery). In contrast, for diverse tampering, only localization is realized. This paper presents a recovery method for the scheme most tolerant against diverse tampering. We analyze the error probability and confirm that the error probability is significantly small. We also show two variations based on the fact that the authentication data used for deriving the watermark is a maximum length sequence code. |
