Systems and Methods for Secure Transaction Management and Electronic Rights Protection

A system for controlling use and distribution of digital works, in which the owner
of a digital work (101) attaches usage rights (102) to that work. Usage rights are granted by the
"owner" of a digital work to "buyers" of the digital work. The usage rights define how a
digital work may be used and further distributed by the buyer. Each right has associated with it
certain optional specifications which outline the conditions and fees upon which the right may
be exercised. Digital works are stored in a repository. A repository will process each request
(103,104) to access a digital work by examining the corresponding usage rights (105). Digital
work playback devices, coupled to the repository containing the work, are used to play, display
or print the work. Access to digital works for the purposes of transporting between
repositories (e.g. copying, borrowing or transfer) is carried out using a digital work transport
protocol. Access to digital works for the purposes of replay by a digital work playback
device(e.g. printing, displaying or executing) is carried out using a digital work playback
protocol. Access is denied (106) or granted (107) depending whether the requesting repository
has the required usage rights.

System for controlling the distribution and use of digital works

A system and method for communicating information between a first party and a second party, comprising the steps of receiving, by an intermediary, an identifier of desired information and accounting information for a transaction involving the information from the first party, transmitting an identifier of the first party to the second party, and negotiating, by the intermediary, a comprehension function for obscuring at least a portion of the information communicated between the first party and the second party. The data transmission may be made secure with respect to the intermediary by providing an asymmetric key or direct key exchange for encryption of the communication between the first and second party. The data transmission may be made secure with respect to the second party by maintaining the information in encrypted format at the second party, with the decryption key held only by the intermediary, and transmitting a secure composite of the decryption key and a new encryption key to the second party for transcoding of the data record, and providing the new decryption key to the first party, so that the information transmitted to the first party can be comprehended by it.

System and method for secure three-party communications

An adaptive interface for a programmable system, for predicting a desired user function, based on user history, as well as machine internal status and context. The apparatus receives an input from the user and other data. A predicted input is presented for confirmation by the user, and the predictive mechanism is updated based on this feedback. Also provided is a pattern recognition system for a multimedia device, wherein a user input is matched to a video stream on a conceptual basis, allowing inexact programming of a multimedia device. The system analyzes a data stream for correspondence with a data pattern for processing and storage. The data stream is subjected to adaptive pattern recognition to extract features of interest to provide a highly compressed representation that may be efficiently processed to determine correspondence. Applications of the interface and system include a video cassette recorder (VCR), medical device, vehicle control system, audio device, environmental control system, securities trading terminal, and smart house. The system optionally includes an actuator for effecting the environment of operation, allowing closed-loop feedback operation and automated learning.

Adaptive pattern recognition based control system and method

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.

Systems and methods for matching, selecting, narrowcasting, and/or classifying based on rights management and/or other information

A data communication system providing for the secure transfer and sharing of data via a local area network and/or a wide area network. The system includes a secure processing unit which communicates with a personal keying device and a crypto media controller attached to a user's Workstation. The communication between these processing elements generates a variety of data elements including keys, identifiers, and attributes. The data elements are used to identify and authenticate the user, assign user security access rights and privileges, and assign media and device attributes to a data access device according to a predefined security policy. The data elements are manipulated, combined, protected, and distributed through the network to the appropriate data access devices, which prevents the user from obtaining unauthorized data.

Data enclave and trusted path system

A method and apparatus for ensuring secure communication over an unsecured communications medium between a user working on an unsecured workstation or computer and a host computer. A secure user interface is created by inserting a trusted path subsystem between input/output devices to the workstation and the workstation itself. Data transferred from the input/output devices is intercepted, encrypted and transmitted in packets to the host computer. Packets of screen display data from the host computer are decrypted and presented within a user-defined screen overlay.

Trusted path subsystem for workstations

Communication elements for secure data communication between remote nodes of a computer system on a standard communications medium (12). Terminals (21), workstations and personal computers are connected through a user-side terminator to a standard unsecured communications medium (12). Processors (42) are connected through a computer-side terminator (41) to the same medium (12). The combination of a user-side terminator (21), a computer-side terminator (41) and a standard communications medium (12) constitutes a secure computer interface.

Secure computer interface

A system and method for identifying and authenticating users and for controlling the access of those users to privileged instructions within a data enclave The data enclave includes a plurality of controllers, such as workstations, connected over a network to a security server; each data enclave is assigned a cryptographic key A personal keying device having an encrypted user unique identifier is assigned to each user; provisions are made for temporarily connecting the personal keying device to one of the controllers and for transmitting an encrypted message, including the user unique identifier and the last countersign, to the security server to authenticate the user and establish his/her access rights A mechanism for updating the countersign is provided so that trusted path communications can be established between the user and the security server
