Widevine Awarded Patent

SEATTLE -- Widevine Technologies, the world's leading provider of downloadable content protection, forensic watermarking and digital copy protection solutions, today announced that the United States Patent and Trademarking Office has awarded Widevine a new patent for digital copy protection. This patent covers innovative new techniques that are essential to securing Internet delivery of premium multimedia content to untrusted platforms such as personal computers.

The new patent also includes methods for monitoring, detecting and responding to piracy in what is known as the "digital hole" -- the location within digital consumer devices where content is unprotected, usually after content is decrypted by a conditional access or digital rights management solution. Widevine Digital Copy Protection(TM) monitors this hole for piracy behaviors, blocks them and evolves response mechanisms to thwart future attacks.

Some of the concepts taught by Widevine's latest patent include:

  • Behavioral tamper and piracy detection

  • Tamper and piracy response

  • Heuristics for automatic evolution of detection mechanisms

  • Stealthy detector techniques

According to Glenn Morten, Widevine's Chief Technology Officer, "To foil multimedia piracy acts, Widevine developed genetic programming, artificial intelligence and intrusion detection methods to create a shifting sands environment that it is extremely difficult for pirates to beat. These patented protection methods are important as mainstream television migrates to webisodes and webcasts that are streamed to PCs across the Internet. Other methods of protecting content have been devised, including Microsoft® Windows Vista(TM) (Nasdaq:MSFT - News), CableLabs DCAS and other secure video processor initiatives. However, while these are good security practices, they are static and lack the ability to perform dynamic evolution in the face of new piracy attacks. Evolving detectors taught within this new patent give Widevine the unique ability to adapt our content security mechanisms in real time."
