The Fingerprinting Algorithm for Digital Image and Video

摘要

Most of the current techniques for data-hiding in images utilize some decomposition for embedding the message bits. But in this paper, we use the watermark method based spatial domain for the message bits. The representative method of spatial schemes is pulse amplitude modulation and spread spectrum method. We increased the payload of embedding data with modifying spread spectrum method. Although the fingerprint is one of watermarking applications, the fingerprint is more critical than watermarking. Specially, the robustness to collusive attack is very an important element in the fingerprint. The fingerprint must make least influence on each other of embedding data because we must extract least one-user information, at collusive attack. In this paper, we embedded the fingerprint based spatial domain and the fingerprint was robust to collusive attacks.
