The present invention relates to digital rights management. In one embodiment, persons, processes, and / or computers and appliances locate, share, publish, retrieve, and use all kinds of digital information that has been protected using digital rights management technologies. Rights management includes securely associating rules for authorized use with the digital information. Rules and / or digital information may be encapsulated in a cryptographically secure data structure or "container" ("CSC") to protect against unauthorized use, to ensure secrecy, to maintain integrity, and to force the use of a rights management system to access the protected information. Attributes or metadata information describing at least some of the rules ("rules-metadata information") and optionally any associated rule parameter data with respect to the protected information are created. This rules-metadata information may be organized, structure, encoded, and / or presented using a self-defining data structure such as those created using Extensible Markup Language (XML). In one embodiment, the XML-encoded rules-metadata information is also made available unencrypted, in plain text, to facilitate P2P search and file transfer. Having at least some of the rules-metadata information outside or external to a CSC allows greater flexibility in searching based at least in part upon the rules-metadata information. Some embodiments may hold the rules-metadata information in a separate CSC. Putting the rules-metadata information in a separate CSC more easily allows authentication and maintains the integrity of the rules-metadata information. In another embodiment, the rules metadata may be in an unencrypted portion of a CSC itself or concatenated with a CSC in a single file.

The data security method, system and associated data mining enables multiple users, each having a respective security clearance level to access security sensitive words, data objects, characters or icons. The method extracts security sensitive words, data objects, characters or icons from plaintext or other source documents to obtain (a) subsets of extracted data and (b) remainder data. The extracted data is, in one embodiment, stored in a multilevel security system (MLS) which separates extract data of different security levels with MLS guards. Some or all of the original data is reconstructed via one or more of the subsets of extracted data and remainder data only in the presence of a predetermined security level. In this manner, an inquiring party, with the proper security clearance, can data mine the data in the MLS secured storage.

A code inspection tool comprises a plurality of physical computing resources connected by a network facility, eg an LAN, intranet or internet, and a voice conferencing communications facility. The code inspection tool interfaces with a known configuration management system to load a quantity of original source code. A group of developers use a plurality of graphical user interfaces to inspect the code. All graphical user interfaces log into display views generated on a main graphical user interface, which is operated by a human controller of a code inspection session. The code inspection tool comprises means for allowing developers to compile annotation data and forward the annotation data from their respective graphical user interfaces to a centralized data store. Internal algorithms of the code inspection tool compile markers relating the annotation data files to individual lines of source code. During a code inspection session, all developers view a same display, which sets out original source code, side by side with new source code on a line by line basis, matching the line numbers of the original source code with those of the new source code. Changes to the original source code and new source code are visually identified by automatic generation of icons next to the appropriate source code lines on the display. Annotations to the source code lines are indicated by further icons next to the appropriate lines. The tool automatically generates data describing statistics of a code inspection process, for example number of lines inspected, during of a code inspection session, proportion of original and new code lines inspected. Code inspection reports may be generated in a variety of formats, eg plain text or HTML, and automatically distributed to individual developers over the networked facility.

A data security having parsing and dispersion aspects enables the user to parse, disperse and reconstruct the original, plain text data or data object, thereby enabling secure storage of the data. The original data may be maintained in its original state, encrypted or it may be destroyed. For example, financial data maintained by an institute, stored as is customary, be parsed with an algorithm, the parsed segments dispersed off-site (that is, separated and stored in extract and remainder stores or computer memories) and away from the financial institute, and, upon appropriate security clearance, the dispersed data can be reconstructed to duplicate the data. Large distribution of parsed data is contemplated by the system. The original data remains stable, operable and immediately useful in its customary storage location (or alternatively destroyed). The secured dispersed data is a back-up of the original data.

The present invention provides encryption schemes and apparatus which securely generate a cipher-text which in itself contains checks for assuring message integrity. It also provides compatible decryption schemes confirming message integrity. The encryption scheme generates a cipher-text with message integrity in a single pass with little additional computational cost, while retaining at least the same level of security as schemes based on a MAC. One embodiment encrypts a plain-text message by dividing the plain-text message into a multitude of plain-text blocks and encrypting the plain-text blocks to form a multitude of cipher-text blocks. A single pass technique is used in this process to embed a message integrity check in the cipher-text block. A message integrity check is embedded in the cipher-text blocks by embedding a set of pseudo random numbers, which may be dependent, but are pair-wise differentially uniform. We also describe an embodiment which is highly parallelizable.

In the conventional technique for mainly performing access control, an entity (an individual) which provides information cannot grasp a state of use of personal information. In the conventional technique for encrypting stored data, a decryption key is always required when personal data is used and the personal data is not protected once decrypted. The invention constitute a system such that a purchase history is collected according to an anonymous ID and a response from a member card or an agent server is required for operation for associating the anonymous ID with a personal ID. Personal data itself is not encrypted but stored in a plain text with the personal ID and the anonymous ID as keys such that the anonymous ID is regenerated every time the anonymous ID is associated with the personal ID on a server side. At this point, the anonymous ID serving as a collection key for the purchase history, which is accumulated concurrently, is also regenerated.
