Widevine® Intellectual Property Portfolio Expands in Asia

New patent covers downloadable conditional access, mobile media DRM & copy protection of HD DVD formats

SEATTLE, November 26, 2007 — Widevine Technologies, the world’s leading provider of downloadable content protection, forensic watermarking and digital copy protection solutions, today announced that the Republic of Korea Intellectual Property Office has issued a new patent which provides intellectual property protection for next generation content protection.

Some of the important concepts taught in this patent include:

• Use of selective encryption to copy protect content
• Uniquely binding a key pair to a player
• Employment of user identity to gain access to the key chain
• Private key associated with a public key with the private key being constrained to the player apparatus
• Player that possesses tamper detection and response agents
• Tamper response mechanisms such as erasing the content, locking the apparatus from an operation, erasing the private key, erasing the content key and reporting the unauthorized action

"For many years Widevine has envisioned selective encryption and downloadable security as key enablers in the convergence of consumer electronics and digital television. With this new patent, Widevine enables consumption of entertainment on mobile devices and retail available devices while reducing the possibility of digital content theft,” said Glenn Morten, Widevine’s Chief Technical Officer and the patent’s author. “Secure content delivery backed by intellectual property protection is very important to Widevine’s Korean consumer electronics partners.”

The new patent (KR 10-0749947-0000) is intended to provide a licensed solution for next generation content protection systems which are focused on downloadable conditional access, mobile media security and copy protection of high definition DVD formats such as Blu-ray®, HD-DVD and other formats. This is the ninth issued patent for Widevine, represented by Darby and Darby. Other patents issued to Widevine include U.S. 6,449,719 B1, U.S. 6,965,993 B2, U.S. 7,007,170 B2, U.S 7,043,473, U.S. 7,150,045, R.O.C. 1268080, U.S. 7,165,175, KR 10-0747755-0000 and US 7,299,292.
