Abstract
- Commutative encryption and watermarking ( CEW) is a combination of cryptographic and digital watermarking technology, which is used for multimedia information security and copyright protection. In order to ensure the security of carrier data, this paper proposed an exchange encryption watermarking algorithm based on ZUC. The algorithm used the ZUC sequence cipher to generate the key and used modular operation to encrypt the carrier information. The sequence of watermark embedding operation and data encryption operation did not affect the generation of watermark ciphertext data. When extracting the watermark, the algorithm could realize the exchange of password operation and watermark operation. The experimental results show that the watermark extraction in ciphertext domain is consistent with that in plaintext domain, the image containing watermark is of high quality, the efficiency of encryption and decryption, watermark embedding and extraction are higher, and the algorithm has a certain robustness.
