Asymmetric watermarking scheme using permutation braids

Abstract

In this paper, we propose asymmetric watermarking system using permutation braids. Asymmetric watermarking system uses different keys for watermark embedding and detection. In such a scheme, the detector only needs to know a public key, which does not give enough information to make watermark removal possible. The proposed watermarking scheme can match requirements of asymmetric watermarking system. Our experimental result shows that this scheme provides security from any attempts to identify or remove the secret key. © Springer-Verlag 2004.
