Title: Method for inserting robust electronic watermark to signal and method for detecting electronic watermark
Inventor: COX INGEMAR
IPC: H04N7/24
Filed: 2004-05-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a digital electronic watermarking procedure that is applicable to images, audio, video and multimedia data.  <P>SOLUTION: The electronic watermarking procedure divides the data to be watermarked into a set of n×n blocks, such as the 8×8 blocks of MPEG. The blocks are summed to form one total block to which electronic watermark is inserted. The same electronic watermark signal can be distributed throughout the set of blocks in a large variety of ways. This allows the insertion algorithm to be changed without affecting the decoders. The decoding procedure first sums together the DCT coefficients of N sets of 8×8 blocks and then extracts the electronic watermark from the summed block. Since the sum of the DCT blocks is equal to the DCT of the sum of the pixel value blocks, efficient decoding can occur in both the spatial and frequency domains. The symmetric nature of the decoding process allows geometric distortions to be handled in the spatial domain and other signal distortions to be handled in the frequency domain.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
