| Abstract(in English) | Digital watermarking, which is mainly used for protecting the copyrights of digital contents, can also applied as a technique to detecting malicious alteration. Especially a fragile digital watermarking is applicable to localize alterations in digital images. This localization is required to be able without original data and be useful for any alterations. And to consider releasing the algorism, it is desirable to key for protecting the secureness. In this paper, we newly suggests a localizing alteration technique using a fragile digital watermarking based on number theoretic transform (NTT). In addition, this discusses that our method may be useful to recover alterations. |
