Digimarc Gets Four Patents

Digimarc, the content-security and watermarking company, has received four new patents. “U.S. Patent Number 6,400,827 was issued last month by the U.S. Patent Office and covers techniques that enable a digital watermark embedded into digital movies or imagery to survive typical manipulations encountered during content distribution. Such techniques have been widely advocated for use in applications like copy protection and copyright management.”

In addition, Digimarc recently expanded its video watermarking assets by acquiring video watermarking technology, software and two pending U.S. and Australian patent filings from Telstra, an Australia-based telecommunications and information services company.
