This paper studies a novel scheme of watermarking relational databases for copyright protection. Speech signal is introduced as watermark to be embedded into the relations; associated novel watermark insertion algorithm and detection algorithm are proposed. Thus, the watermark signal in this method is expected to be more meaningful and has closer(More)
By introducing public key cryptography, a novel algorithm for watermarking relational databases is proposed. In this algorithm, asymmetric keys are used in insetting and detecting database watermark processes, and users canpsilat get anything of the private key copyright watermark information or destroy database watermark through public key. Watermark(More)
This paper studies a novel scheme of watermarking relational databases for copyright protection based genetic algorithms. In this algorithm, GA is used in watermark signal processes, and associated novel watermark insertion algorithm and detection algorithm are proposed. Thus, the watermark signal in this method is expected to be more meaningful and has(More)
 Buyer-seller watermarking protocols are designed to deter clients from illegally distributing copies of digital content. To be efficient and fair is important to buyer-seller protocols. In this paper, an anonymous and interactive buyer-seller protocol is proposed, which is designed to be impartial and efficient. To solve the unbinding problem and the(More)
This paper presents an algorithm of iterative construct reversible network by cascade operation. The cascade operation was implemented with Boolean permutation. We proposed two important decision condition of Boolean permutation, and changed to choose balance function of suffice Boolean permutation condition for the problem of construct reversible network.(More)
