Abstract

Through in-depth study of the existing discrete cosine transform (DCT) watermarking technology, this paper presents a double encryption watermarking algorithm to enhance the security of watermark information. In the watermark embedding stage presents a new adaptive blind watermarking algorithm based on DCT domain, to achieve binary watermark embedding after double encryption. This algorithm effectively reduces the complexity of the watermark extraction algorithm, and ensures the security of watermark while improving the invisibility, so it has a strong confidentiality, robustness and resistance to attack.
