一种混沌置乱的DCT域数字水印算法
DCT Watermarking Algorithm Based on Chaotic Scrambling
【摘要】 以Logistic混沌序列构成加密模板来置乱二值水印图像,在DCT变换域进行水印嵌入。该算法符合密码学要求,且仿真结果表明不可见性和鲁棒性良好。
【Abstract】 The algorithm uses Logistic chaotic sequences to scramble a binary watermarking image which is embedded into an original image by DCT and tested by nonblind correlation. It conforms to demands of cryptography, and experiments show its better invisibility and robustness.
