基于混沌加密的彩色图像盲数字水印算法
Blind Digital Watermark Algorithm for Color Images Based on Chaotic Encryption
摘要
Abstract
In order to increase the security of chaos-based encryption algorithm while not affecting the performance, a kind of encryption algorithm based on a two-dimensional Chebyshev maps with the combination of the m-sequence of the chaos is put forward. During the embedding of the watermark, discrete wavelet transform is done to the green luminance of RGB color space and low frequency part is extracted as the embedding field. The watermark is encrypted by using the compound chaotic sequence and is embedded into the low frequency part of the green luminance. Experimental results show that this watermark technique, in which the encrypting and embedding algorithms have less computational capacity, can resist JPEG compression, noise attack, filter and so on, as well as good digital watermark performance.关键词
