说明： 利用同一密钥的混沌序列对经过置乱的水印信息实现双重加密，考虑小波变换的能量分布问题，把水印信息嵌入低频系数中，确保水印信息的可靠性。提取时利用图像复原方法实现盲检测。
(Using the same key after a chaotic sequence of scrambling the watermark information to achieve the double encryption, consider the wavelet energy distribution problem, the watermark information embedded in low-frequency coefficients to ensure the reliability of watermark information. Extracted using image restoration method to achieve blind detection.)
