A novel binary image digital watermarking algorithm based on DWT and chaotic encryption is proposed. The proposed scheme utilized the Logistic chaotic sequences and generalized cat mapping to scramble the watermarks, so that the security of embedding watermarks was enhanced. The improved binary method was utilized and watermarks are embedded to the low frequency coefficients of deep wavelet domain. The original image is not required for detecting the watermarks .Using the statistical method the veracity is improved. The experimental results show that the watermark is robust against the cut attack, salt-pepper noise attack, JPEG and et al.
