摘　　要：根据脆弱性水印图像认证系统的要求,提出了一种基于RGB通道和混沌系统的脆弱性多重水印算法.利用通道将RGB彩色图像分解为3幅灰度图像,在图像的R,G,B通道上进行水印的处理,在不同的通道上可以嵌入多个水印,嵌入的水印数据量相对较大,而且多个水印可以起到多重保险的作用.通过密钥和阈值计算得到二值混沌序列,使得水印的嵌入不容易被篡改、攻击,其方法简单,容易实施,取得了较好的隐藏效果.According to the fragility of the watermark image authentication system requirements, a channel based on the RGB and the vulnerability of chaotic systems multiple watermarking algorithm. The algorithm in the image of R, G, B channel on the deal with watermarking, because of the different number of channels can be embedded watermark, the watermark embedded in a relatively larger amount of data and a number of watermarks can play the role of multiple insurance. The method is simple and easy to implement, and achieved good effect hide.
