An algorithm for embedding digital watermarks into the memory of the executable program is proposed. Digital watermarks are used for copy protection and copyright confirmation of digital objects. The proposed approach makes it possible to form a digital watermark in the operative memory of an executable program for a limited period of time. The address of the embedded information in RAM is random, which greatly complicates its detection and identification. Extraction of digital watermark is performed by passphrase. The embedding, extraction and removal of a digital watermark is implemented using a dynamic library, which is an integral part of the user authentication process, which prevents third-party removal of the digital watermark.
