Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and method for embedding and extracting digital watermarks based on wavelets which is robust to external attacks while being capable of minimizing a degradation in picture quality caused by embedding of the watermarks. SOLUTION: The embedded watermarks embedded in DC component domains of wavelet-transformed domains can be robust to external attacks such as compression in the case of embedding and extracting watermarks for copyright protection. The high-frequency dependency of pixels in a DC component domain determined as a target domain, in which watermarks are to be embedded, is calculated, in order to embed the watermarks in the target domain in the order of pixels having a higher high-frequency dependency. Accordingly, there is an advantage in that it is possible to minimize a degradation in picture quality caused by the embedding of watermarks in the DC component domain. COPYRIGHT: (C)2003,JPO

Abstract: A method and an apparatus for inserting a forensic mark for protecting the copyright of the digital camera contents are provided to protect the copyright of the digital cinema contents efficiently by inserting the forensic mark in a lifting-based wavelet conversion process. Wavelet converters(200,210) change the digital video data into lifting based wavelet. A forensic mark generating unit(214) produces the forensic mark for the digital right protection. A forensic mark insertion unit(212) comprises the lifting step so that the return value of the wavelet conversion be identical regardless of the added lifting parameter value. The forensic mark insertion part provides the forensic equation mark to the wavelet converter. The forensic equation mark is inserted into the intermediate result value among a plurality of lifting steps.
