摘要:
An auxiliary device control for a subscriber terminal includes a four wire ribbon cable defining a bidirectional communication and data interface from the terminal to one or more auxiliary devices. A communication and data protocol for the bidirectional transfer of instructions, status, and data over the interface includes an address field, command or reply field, data length field, and checksum field transmitted at 9600 baud. In a preferred implementation, the auxiliary device to be controlled is an IR peripheral controller which can tune a VCR, and switch it on and off. Several transactions in the communications and data protocol are used to effect the operation where a control VCR command and reply transaction cause the control of the tuning and recording of the VCR. A set-up VCR command and a brand reply transaction is used to provide information to configure the controller with brands and model of the VCRs. A program event code command and a program event timer reply transaction provide for the automatic recording of a program event based on an event code listed in a television schedule. A channel map command and a reply transaction provide for the downloading of the local cable system channel line up into the controller.

A method and apparatus for managing use of protected content by providing a specific user interface to an application program used to render the content. The method includes identifying a user interface description associated with content, building a specific user interface based on the user interface description, and replacing the standard user interface of an application program used to render the content with the specific user interface. The specific user interface can be unique to the user, unique to a Web site, or otherwise customized.

A system and method for the secure distribution and consumption of electronic documents using a standard rendering engine. The documents can usage rights associated therewith. A server stores at least one of the documents in computer readable form. A client having a standard application program including a rendering engine capable of rendering unencrypted documents for viewing is operated by a user. The client and the server are coupled by a communications network. A security module controls requested for at least one of the documents on the server from the client and delivers the document and a set of rights associated with the document to the client.
摘要:
A method and apparatus for managing and accomplishing on-line transactions while preserving the privacy of user information. User information is stored at a trusted Web site. A user logs on to a transacting Web site with a user device and requests a transaction from the transacting Web site. The user is verified through the trusted Web site using an anonymous identifier corresponding to the user information and the transaction is accomplished between the user device and the transacting Web site using the anonymous identifier without transferring the user information to the transacting Web site.
摘要:
A system and method for encrypting content in an adaptive manner. Portions of data to be encrypted are identified and an encryption ratio that specifies the one or more portions of data to encrypt and other portions of data to not encrypt is determined. The data is then encrypted based on the encryption ratio.
摘要:
A system and method of controlling use of content in accordance with usage rights associated with the content. A request for content is analyzed by looking for a signature from a user device making the request to determine if the user device has security components for enforcing the usage rights. If the request does not have the signature, a software agent is sent to the user device to determine if the user device is secure and the request is resent with the signature if the user device is secure. Content is rendered with a rendering engine of the user device in accordance with the usage rights in response to the resent request.

摘要:
A system and method for controlling use of content in accordance with usage rights associated with the content and determined in accordance with the environment of a user device. A request is received for secure content from a user device and the integrity of the environment of the user device is verified. Appropriate usage rights are retrieved based upon the results of the verification of integrity and the content is rendered on the user device in accordance with the appropriate usage rights.
