27 Aug, 2002 By: Hive News


The U.S. Patent Office has awarded Verance Corp. two new patents for digital watermarking technology, bringing the total number of U.S. patents awarded to the company to 20.

U.S. Patent No. 6,427,012, "Apparatus and Method for Embedding and Extracting Information in Analog Signals using Replica Modulation " relates to generic techniques for encoding and decoding digital watermarks within cover signals such as audio or video signals.

The watermarking techniques covered by this patent have a variety of applications, including tracking and managing the use of media content in radio and television broadcasts and over the Internet.

U.S. Patent No. 6,430,301, "Formation and Analysis of Signals with Common and Transactional Watermarks," covers a class of digital watermarking techniques for marking individual copies of audio or audiovisual content with unique embedded codes that allow them to be subsequently traced back to their source, which could be a specific copy of a CD or DVD, a specific Internet download or streaming event, or a specific broadcast or public performance. These techniques can be used to detect and deter unauthorized distribution and use of copyrighted works by providing a means to identify the source of the unauthorized copies.

"These new patents further extend Verance's leadership in the development of digital watermarking technologies that address the greatest challenges faced by owners and distributors of media content in identifying uses of copyrighted works," said Verance CTO Joseph Winograd. "They illustrate our company' s continued commitment to providing innovative solutions for adding accountability and audit capabilities across all media formats and distribution platforms.”
