- W1002413449 abstract "The sensitive or private information in frames, which should not be viewable by the general public or regular users, will be scrambled by directly modifying or removing the related data in H.264/AVC compressed bit streams. A privacy protection mechanism in H.264/AVC videos is proposed, in order to allow the authorized users to recover the partially scrambled video frames, the methodology of information hiding is employed; that is, the correct information is embedded and transmitted along with the video bit stream. After retrieving the data, the authorized users can descramble the protected areas in frames. The conventional information hiding methods in the compressed video domain, focusing on the H.264 video compression standard is being used. Our study is based on Discrete Wavelet Transform (DWT) which is based on H.264/AVC intra prediction." @default.
