PROBLEM TO BE SOLVED: To solve the problem, wherein it is impossible for an electronic content information provider to provide commercially secure and effective method, for a configurable general-purpose electronic commercial transaction/distribution control system. SOLUTION: In this system, having at least one protected processing environment for safely controlling at least one portion of decoding of digital information, a secure content distribution method comprises a process for encapsulating digital information in one or more digital containers; a process for encrypting at least a portion of digital information; a process for associating at least partially secure control information for managing interactions with encrypted digital information and/or digital container; a process for delivering one or more digital containers to a digital information user; and a process for using a protected processing environment, for safely controlling at least a portion of the decoding of the digital information.

Systems and Methods for Secure Transaction Management and Electronic Rights Protection

Multiple applications request data from multiple storage units over a computer network. The data is divided into segments and each segment is distributed randomly on one of several storage units, independent of the storage units on which other segments of the media data are stored. At least one additional copy of each segment also is distributed randomly over the storage units, such that each segment is stored on at least two storage units. This random distribution of multiple copies of segments of data improves both scalability and reliability. When an application requests a selected segment of data, the request is processed by the storage unit with the shortest queue of requests. Random fluctuations in the load applied by multiple applications on multiple storage units are balanced nearly equally over all of the storage units. This combination of techniques results in a system which can transfer multiple, independent high-bandwidth streams of data in a scalable manner in both directions between multiple applications and multiple storage units.

Computer system and process for transferring multiple high bandwidth streams of data between multiple storage units and multiple applications in a scalable and reliable manner

Multiple applications request data from multiple storage units over a computer network. The data is divided into segments and each segment is distributed randomly on one of several storage units, independent of the storage units on which other segments of the media data are stored. Redundancy information corresponding to each segment also is distributed randomly over the storage units. The redundancy information for a segment may be a copy of the segment, such that each segment is stored on at least two storage units. The redundancy information also may be based on two or more segments. This random distribution of segments of data and corresponding redundancy information improves both scalability and reliability. When a storage unit fails, its load is distributed evenly over to remaining storage units and its lost data may be recovered because of the redundancy information. When an application requests a selected segment of data, the request may be processed by the storage unit with the shortest queue of requests. Random fluctuations in the load applied by multiple applications on multiple storage units are balanced nearly equally over all of the storage units. Small data files also may be stored on storage units that combine small files into larger segments of data using a log structured file system. This combination of techniques results in a system which can transfer both multiple, independent high-bandwidth streams of data and small data files in a scalable manner in both directions between multiple applications and multiple storage units.

Rights management information is used at least in part in a matching, narrowcasting, classifying and/or selecting process. A matching and classification utility system comprising a kind of Commerce Utility System is used to perform the matching, narrowcasting, classifying and/or selecting. The matching and classification utility system may match, narrowcast, classify and/or select people and/or things, non-limiting examples of which include software objects. The Matching and Classification Utility system may use any pre-existing classification schemes, including at least some rights management information and/or other qualitative and/or parameter data indicating and/or defining classes, classification systems, class hierarchies, category schemes, class assignments, category assignments, and/or class membership. The Matching and Classification Utility may also use at least some rights management information together with any artificial intelligence, expert system, statistical, computational, manual, or any other means to define new classes, class hierarchies, classification systems, category schemes, and/or assign persons, things, and/or groups of persons and/or things to at least one class.

A system of distributing video and/or audio information employs digital signal processing to achieve high rates of data compression. The compressed and encoded audio and/or video information is sent over standard telephone, cable or satellite broadcast channels to a receiver specified by a subscriber of the service, preferably in less than real time, for later playback and optional recording on standard audio and/or video tape.

(57) [Summary] [Problem] KR as key distribution structure of tree structure Provided is an information recording / reproducing apparatus which distributes a key by B distribution and makes processing on a KRB receiving side more efficient. SOLUTION: A key (a master key, a media key, a content key, or the like) is formed by a key distribution structure having a tree structure. Is transmitted together with the key update block (KRB). Based on the received KRB, the recording / reproducing apparatus calculates and obtains a key of a certain recording medium, and then encrypts the obtained key using an encryption key unique to the recording / reproducing apparatus, for example, a leaf key, to obtain a recording medium, or It is configured to be stored in the memory of the recording / reproducing device. Therefore, the next time the recording / reproducing apparatus uses the recording medium or the content, the key can be calculated only by decrypting the encryption key once, and when the recording / reproducing apparatus accesses the recording medium or uses the content. It is possible to reduce the amount of calculation such as the KRB decoding process required for (1).

A CPU (12) of a data transmitter (10) crates simple copy control information roughly defining the copy control status of data to be transmitted according to minute copy control information defining the copy control status of the data, adds the simple copy control information to the packet header of a data packet for transmitting the data, add the minute copy control information to the data, and transmits the simple and minute copy control information along with the data from an input/output interface (16) through a transmission line (30) to a data receiver (20). A CPU (22) of the data receiver (20) analyzes the copy control status of the data contained in the data packet on the basis of the simple and minute copy control information contained in the data packet, and conducts copy control of the data by means of a media access section (26) according to the results of the analysis.

SOLUTION: An information providing device 200 side distributes an information medium having encrypted information to a user terminal 400 side, the information providing device 200 is connected to the user terminal 400 through a communication network, and the information providing device 200 and the user terminal 400 transmit and receive information through the communication network. The information providing device 200 uses a user ID and a password belonging to the user terminal 400 to encrypt the key information required to decrypt encrypted information of the information medium, and the user terminal 400 uses the user ID, the password and a reader ID to decrypt the encrypted key information transmitted from the information providing device 200. In addition, the user terminal 400 uses the key information to decrypt encrypted information read from the information medium. COPYRIGHT: (C)2005,JPO&NCIPI
