| Abstract(in English) | Digital watermarking, which is mainly used for protecting the copyrights of digital contents, is also considered as a technique for detecting malicious alterations on such digital data. Since digital data are easily duplicated with some slight changes, it is required that the detection should be sensible for such little alterations. Ideally, the detection is required to be able without an original data. We newly proposes a method that satisfies the above requirements based on the number theoretic transform(NTT). This paper shows how effectively the proposed method can work for detecting alterations on some still images. |
