Abstract:
Abstract Commutative Encryption and Watermarking (CEW) combines encryption and watermarking to provide a comprehensive security protection for multimedia data. On the other hand, the storage and transmission is an important dilemma due to enormous size of multimedia data, therefore an effective solution to both bandwidth and storage problem is the use of data compression. In this paper, we propose a commutative watermarking and encryption (CEW) scheme for jpeg2000 compression standard.The commutative property of the proposed scheme allow to encrypt a watermarked image without interfering with the embedded watermark, or to watermark encrypted image and still allowing a perfect decrypting. The encryption and watermarking are carried out after the quantization step in jpeg2000 compression standard. It is based on decomposed data after quantization into two parts. One part is encrypted and the other is watermarked. The security of the scheme is assured since the encryption and watermarking is implemented in compressed domain. Experimental Results show the effectiveness of the proposed scheme. Keywords: JPEG2000, Encryption, Watermarking, Commutative Encryption and watermarking scheme (CEW)
