Method for encrypting medical image robust watermark based on DCT (Discrete Cosine Transform) ciphertext domain

Номер: CN104867102A
Автор: LI JINGBING, CHEN YANWEI, FU WEIBIN, TU RONG
Принадлежит:

The invention relates to a technology for encrypting a medical image watermark based on DCT (Discrete Cosine Transform) and Logistic Map, and belongs to the field of multimedia signal processing. In the steps of the technology, preprocessing of an original medical image and embedding of the watermark are performed firstly. The technology comprises the following steps: (1) acquiring an encrypted image with the DCT and the Logistic Map; (2) performing DCT on the encrypted image, and extracting a feature vector; (3) acquiring a binary logical sequence with the feature vector and a watermark sequence; and performing extraction of the watermark, including: (4) performing DCT on an encrypted medical image to be tested, and extracting one feature vector; (5) extracting the watermark with a Hash function and the binary logical sequence generated during embedding of the watermark; and (6) generating a binary encryption matrix with the Logistic Map to obtain a reduced decrypted medical image. In ...

The invention discloses a technology for encrypting a medical volume data digital watermark under a cloud environment and belongs to the field of multimedia signal processing. The steps of the invention are as follows: firstly using nature of Logistic Map to carry out symbol encryption to volume data, then carrying out 3D-DCT conversion to encrypted volume data to extract a feature vector to insert a watermark, associating the feature vector and a binary watermark to obtain a binary logic sequence and storing the binary sequence to a third party; carrying out 3D-DCT conversion to the volume data to be encrypted to extract the feature extract thereof, and associating with the binary sequence stored in the third party. The invention is a technology for encrypting the volume data digital watermark based on three-dimensional DCT with better robustness. The insertion of the watermark does not change the content of the original encrypted volume data, so the invention is a zero-watermark technology ...
