(In)Security of an Efficient Fingerprinting Scheme with Symmetric and Commutative Encryption of IWDWWe analyze the security of a fingerprinting scheme proposed at IWDW 2005. We show two results, namely that this scheme (1) does not provide .: a dishonest buyer can repudiate the fact that he redistributed a content, and (2) does not provide .: a buyer can be framed by a malicious seller.

Reversible Data Hiding Using Prediction Error Values Embeddingations, we propose an even- and odd-number-based embedding method. This method is implemented in a prediction error image. The experimental results show that our embedding method can achieve satisfactory embedding capacity and image quality.

Multiple Watermarking in Visual Cryptographye. In watermark extraction, only Exclusive-OR operation is needed, and basic properties of conventional visual cryptography technique are still preserved. Experimental results show the effectiveness of our schemes.
