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.
