基于置乱和混沌加密的数字图像水印技术研究
STUDY ON DIGITAL IMAGE WATERMARKING TECHNOLOGY BASED ON SCRAMBLING TRANSFORMATION AND CHAOTIC ENCRYPTION
【摘要】 为了进一步增加水印系统的安全性,对经过置乱变换的二值数字图像水印用时空混沌技术进行加密,使攻击者无法解读嵌入的水印.
【Abstract】 To further enhance the watermarking system security, a spatiotemporal chaos system was employed to encode the scrambled binary digital image watermark. This technique makes it impossible for the attackers to decode the embedded watermark.
