Lì Jiāng, Hao Zheng, Chaoxing Zhao · 2021
The current studies of ciphertext watermarking for remote sensing image are mostly focused on the copyright protection. However, the ciphertext data of remote sensing image is at risk of being destroyed, how to ensure the integrity of it is also a problem to be solved. Therefore, aiming at the problem of integrity verification of remote sensing image ciphertext, this paper proposes a ciphertext domain fragile watermarking algorithm by using the multi-permutation superposition coding and the probabilistic encryption. According to the experimental results, the proposed algorithm is highly sensitive to the tamper of ciphertext and can locate the tamper accurately. In addition, the embedding capacity of the proposed ciphertext watermarking is large enough for the copyright protection or other applications, meanwhile, the proposed algorithm will not affect the original remote sensing image date and its future application.
