  • Publication number: 20070291944
    Abstract: Methods and systems for blackout provisioning in a communication network. In an aspect, a method is provided for blackout provisioning in a distribution network. The method includes determining one or more affected regions, and generating a blackout key based an original key and the affected regions. The method also includes encrypting content with the blackout key to produce encrypted content, and transmitting the encrypted content and an encrypted version of the original key over the distribution network. An apparatus is provided for blackout provisioning that includes provisioning logic to determine one or more affected regions, a key generator to generate a blackout key based an original key and the affected regions, encryption logic to encrypt content with the blackout key to produce encrypted content, and a transmitter to transmit the encrypted content and an encrypted version of the original key over the distribution network.

  • Publication number: 20070260881
    Abstract: Systems and methodologies are described that facilitate digital rights management in a wireless communication environment. Generally, content (e.g., data files, video images, etc.) can be downloaded and maintained in its encrypted state to ensure protection of digital rights. Consequently, programming applications that utilize such content decrypt the content at the time of use (e.g., playback or access). A file interface can be provided that allows applications to access encrypted content utilizing a standardized file I/O interface. Decryption of content can be transparent to individual applications utilizing encrypted content. Therefore, modifications cryptographic algorithms or procedures and changes in key sizes need not affect the programming applications.

  • Publication number: 20070206799
    Abstract: A Digital Rights Management (DRM) system provides a lightweight layering of encryption and decryption of keys that allows efficient use of different cryptographic techniques to effect the secure delivery of multimedia content. Asymmetric cryptography, where a public key is used to encrypt information that can only be decrypted by a matched private key, is used by the DRM system to deliver symmetric keys securely.

  • Publication number: 20070016802
    Abstract: A method is disclosed for encrypting a multimedia file including parsing the multimedia file to identify a media data portion; encrypting the media data portion; and, combining the encrypted media data portion with a non-encrypted non-media data portion. A method is also disclosed for playing a multimedia file including parsing the multimedia file to identify an unencrypted metadata portion; using the unencrypted metadata portion to locate a position of interest in the media file, the position of interest having an associated encrypted media data portion; and, decrypting the associated encrypted media data portion. An apparatus for performing the methods is also disclosed herein.

  • Patent number: 6778688
    Abstract: The present invention relates to a method, system and computer program product for enabling the remote authentication of fingerprints over an insecure network using a client-server architecture by generation of a set of random queries relating to fingerprint patterns based on stored fingerprint data at the server, to which the client responds based on the observed fingerprint patterns, followed by the issuing of a randomly generates set of challenges pertaining to geometrical relationships between the fingerprint patterns for which confirm responses are received by their server, the final authentication being determined by the proportion of correct responses by the client to said challenges.
