摘要： A unified broadcast encryption system divides a media key tree into S subtrees, divides digital content into segments, and converts some of the segments into variations; the number of segments and variations is q. The system subdivides each of the subtrees into q/|S| subdivided subtrees, assigns a key media variant to each of the subdivided subtrees, and generates a unified media key block (MKBu). The system decrypts digital content by obtaining required key media variants from the MKBu, using the key media variant to find an entry in a variant key table, decrypt a title key, and locate a variant number from the variant key table. The system uses the variant number to identify which of the variations may be decrypted by the title key and uses the title key to decrypt segments and variations.

摘要： Embodiments of the invention relate to modeling communities associated with groups of data items. Tools are provided to iteratively assign data items to communities and to update topic and participant distribution in the assigned communities. As the distributions are updated, the characteristics of the communities are updated. Each activity area is defined from the perspective of a single user. Participants in a community are connected to a user, but not necessarily to each other. The combination of formations of communities and the statistical aspect of evaluating characteristics of the communities provides a multi-facetted organization of connections between data items and associated participants.

摘要： Embodiments of the invention relate to a method, system, and computer program product to identify broken tag words of a data item and to replace the broken tag words with a compound word. Data items that have at least two tag words are examined to determine if the tag words are broken elements of a compound word. A computational assessment is conducted to determine a relationship between a set of compound words and an examined data item. Based upon the computational assessment a set of broken tag words may be replaced with a related compound word.

摘要： Embodiments of the invention relate to a modeling activity area associated with groups of data items. Tools are provided to profile activity area involvement, both from the data item and from associated participants. The data items are placed into clusters and one or more activity areas are derived from the formed clusters. Each activity area is defined from the perspective of a single user. Participants in an activity area are connected to a user, but not necessarily to each other. The combination of formations of clusters and activity areas provides a multi-facetted organization of connections between data items and associated participants.

摘要： Embodiments of the invention relate to obtaining forensic information for an anonymous attack of digital content without variations in a broadcast encryption system. In one embodiment a media device, being configured to record digital content on recordable media, receives digital content, a unified media key block, and a recording key table. The device calculates a set of recording keys from the recording key table using a media key variant from the unified media key block. The device then generates a title key and encrypts by the digital content in the generated title key. The device then encrypts the generated title key in each one of the calculated recording keys, adds a header including the encrypted titles keys to the encrypted digital content, and stores the encrypted digital content with the header on recordable media.

摘要： A method and system of automatically identifying a set of relevant and qualified recipients to share electronic data is disclosed. The system includes an electronic network configured to store and transmit the electronic data files. The electronic data files include one or more data tags defining a sharing condition that targets potential recipients of the data files or permits access to the data files. A people-tagging system provides an electronic platform including keyword lists (tags) defined by recipient users collaboratively. A matching tool includes software matching recipient users to the data files when the recipient users are associated with keyword lists that satisfy the sharing condition. The method includes tagging a data file by one or more keywords and using a people-tagging system where the recipient users define a list of tags on topics of interest. Recipient users are matched to data files when user lists of tags satisfying the sharing condition.

摘要： A system and method is disclosed for performing unified broadcast encryption and traitor tracing for digital content. In one embodiment a media key tree is divided into S subtrees, the media key tree including media keys and initial values, which may be random values. The digital content is divided into a plurality of segments and at least some of the segments are converted into a plurality of variations. The random values are transformed into media key variations and a separate media key variant is assigned to each of the subdivided subtrees. A unified media key block including the media key tree is stored on the media.
