Abstract
The paper proposes the method of digital watermark usage for video copyright protection, that may be a solution to the piracy of digital content. Digital watermark embedding system should prevent illegal access to the digital watermark and its container. This paper studies different watermark embedding methods for videos. Modified DEW watermarking algorithm is proposed. This method stands out for its technique - the watermark is embedded exclusively by discarding certain high frequency coefficients, however during the extraction label bit errors can occur. Threshold of these errors was found. The watermark was exposed to most of the common attacks, also on low bit-rate videos. Robustness to these attacks was showed. Performance factors of this algorithm were calculated, they depend on three parameters: energy difference, cut-off point and the number of DCT blocks. Effective values of the parameters were found. The suggested method may act as an effective option for copyright protection.
