Method of embedding digital watermark in binary data set e.g. for audio or video data, by combining marked blocks with data stream in accordance with symbols containing watermark

摘要

The method involves dividing the data set into at least m blocks, and marking the blocks with a respective symbol from a group of n symbols, so that each of the blocks is marked individually with the n symbols. All marked blocks are stored in a memory. A digital watermark consisting of symbols from the group of n symbols is embedded by symbol-specifically combining marked blocks with the data stream to be transmitted via the channel, in accordance with the symbols containing the watermark. An Independent claim is included for an encoder.
