摘要： According to one embodiment of the present invention, a system, method, and computer program product is provided for rebinding title keys in clusters of devices with distinct security levels in broadcast encryption systems. The method includes receiving a new management key and unbinding an encrypted title key with a previously used management key, the title key having a security class and residing in a title key block for a device having a security class, the device being in a cluster of devices including devices having a plurality of security classes. If the device security class is lower that the title key security class, the unbound title key is partially rebound with the new management key. the partially rebound title key is then saved in the title key block for the device.

摘要： A system for protecting data in a security system generates and encodes a backup key for encoding long-lived secrets. The system generates a distribution plan for distributing cryptographic splits of the encoded backup key to selected persons based on geographic and organizational diversity. The distribution plan specifies a number M of the cryptographic splits to be generated and a number N of the cryptographic splits required to recover the backup key. The system processes utilize an init file comprising system parameters and state files each comprising parameters reflecting a state of the secure system after a transaction. Any of the state files may be used for any of the system processes. The state files and the init file are encoded by the backup key, thus protecting the long-lived secrets.

摘要： A visual media de-identification system is described. The system includes an image merger and a de-identifying engine. The image merger is configured to merge a sequence of images from a set of visual media data into an averaged image. The de-identifying engine is configured to: bound portions of the averaged image that are determined to be relatively fixed, wherein each bounded portion is identified by a corresponding position in the averaged image; generate a template comprising the bounded portions and the corresponding position for each bounded portion in the averaged image; and de-identify the sequence of images by obfuscating content in the bounded portions.

摘要： Embodiments of the invention relate to digital content protection for recordable media using encryption and decryption based on device keys in the media. The invention increases the number of extended applications supported the media key blocks and facilitates the assignment of the applications to the media key blocks. One aspect of the invention concerns a method that comprises assigning a first media key block in a protected area of the media for extended applications accessing protected content, processing the first media key block with a first device key set to generate a first media key, and for each extended application, creating a second media key block in a protected area of the media. The second media key block is processed to generate a second media key. A content-accessing device processes the first and second media keys in order to access protected content.

摘要： An information access system stores items of information in an unstructured global database. When a user requests access to the system, the system delivers to that user an identification of only those items of information which are believed to be relevant to the user's interest. The determination as to the items of information that are relevant to a user is carried out by ranking each available item in accordance with any one or more techniques. In one approach, the content of each document is matched with an adaptive profile of a user's interest. In another approach, a feedback mechanism is provided to allow users to indicate their degree of interest in each item of information. These indications are used to determine whether other users, who have similar or dissimilar interests, will find a particular item to be relevant.
