Abstract
A method of introducing a non-perceptional signal (watermark) to a digital media data is disclosed. The method is based on the representation of source digital data using a special matrix, insertion of a digital watermark into the special matrix to receive the watermarked matrix, and generation of the watermarked data using the source data and the watermarked matrix. In addition, watermark detection of the watermarked data is performed by calculating the special matrix from the watermarked data.
