Beaverton, Ore. - Digimarc, a developer of digital watermarking technology, announced on Thursday that it has been awarded a U.S. patent for its technology that can identify copyrighted content in social network and peer-to-peer environments. The technology was developed due to media files' ability to easily lose their identifying information during the distribution process, digital-to-analog conversion, or routine file format changes. Oregon-based Digimarc said the technology behind its new patent "teaches ways of identifying entertainment content with digital watermarks and links it to multiple sources of information or services."
