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]. WebAug 25, 2016 · These cryptographic watermarks are embedded as robust or fragile watermarks depending on the required security service. That is, hash codes are commonly used to provide strict integrity of the medical image, whereas CRCs are more appropriately used to detect tampered areas in the image. WebDec 1, 2024 · The proposed crypt-watermarking system allows a good solution against brute force attack which produce a huge key-space of 2768.
