Latest Patents

Broderson holds a patent for a "Token passing technique for media playback devices." This digital rights management (DRM) system is designed for the distribution of digital content, such as audio or video. The system utilizes a token passing scheme to enhance the security of the content from unauthorized access and use, including access by unauthorized players. The token is requested from a central content or DRM server by a host device, such as a user's computer, using security-related information. The token is then passed to a media player associated with the host device, with the token being encrypted using a key specific to that particular player. Upon receipt of the token, the player transmits back to the server certain related security information confirming receipt of the token and, in return, receives keys for decryption of the associated digital content. In the absence of proper passing of the token, player access to the content, or further access to other content, is denied. This system also allows the player to communicate directly with the server for obtaining the keys.
