WebSep 1, 2016 · The jointly watermarking/decryption process is similar to the encryption. Using Ke, the set of indices t j is generated. The s entries of Dk are summed and the result is added to X e giving access to the watermarked vector Xw (7) X w = X e + ∑ j = 1 s D k [ t j] = X + ∑ j = 1 s W k [ t j] = X + M t k where M t k = ∑ j = 1 s W k [ t j]. WebMay 1, 2024 · As a solution, we propose, in this paper, a new crypto watermarking algorithm. The originality of this work lies in joining cryptography with digital watermarking to secure 3D multiresolution meshes. To this end, three steps should be executed.
