A method and apparatus wherein a software scheduling agent resides on a communication network and / or client device, such as location-aware wireless communication appliances, television set top boxes, or other end user client devices is disclosed. The software scheduling agent is part of a probabilistic modeling system in which the scheduler operates to perform constrained random variation with selection. Digital content is generated, organized, and stored on the communication network and / or the client devices. An electronic digital content wrapper, which holds information in the form of data and metadata related to the digital content is associated with each item of digital content. Contextual profiles for each user and each item of digital content are established by the users and the network and maintained by a service provider on the communication network.

A Mixed Media Reality (MMR) system and associated techniques are disclosed. The MMR system provides mechanisms for forming a mixed media document that includes media of at least two types (e.g., printed paper as a first medium and digital content and / or web link as a second medium). In one particular embodiment, the MMR system includes an action processor and method, and MMR documents with an associated action. The MMR document structure is particularly advantageous because the ability to specify different actions for different MMR documents, combined with the ability to create any number of MMR documents for a particular location on any media, allows the MMR architecture to serve as a universal trigger or initiator for additional processing. In other words, addition processing or actions can be triggered or initiated based on MMR recognition. The action processor receives the output of the MMR recognition process which yields an MMR document including at least one action. The action processor executes that action which includes various commands to the MMR system or other systems coupled to the MMR system. The MMR system architecture is advantageous because an action can be executed by pointing the capture device at a block of text, and the action is performed. Example actions include retrieving the text in electronic form to the capture device, retrieving the specification for the action, inserting data to a MMR document, transferring data between documents, purchasing items, authoring actions or reviewing historical information about actions. The MMR system includes a variety of user applications (one or more actions) initiated by the MMR recognition of a text patch such as information retrieval for a travel guide book, stock listings or advertisements; information capture such as recording content from a conference, recording and storing multimedia associated with the document, capturing information for a calendar and on the fly authoring; purchasing media files for storage on any part of an MMR document.

The invention relates to digital rights management, and proposes the implementation of a DRM agent (125) into a tamper-resistant identity module (120) adapted for engagement with a client system (100), such as a mobile phone or a computer system. The DRM agent (125) is generally implemented with functionality for enabling usage, such as rendering or execution of protected digital content provided to the client system from a content provider In general, the DRM agent (125) includes functionality for cryptographic processing of DRM metadata associated with the digital content to be rendered. In a particularly advantageous realization, the DRM agent is implemented as an application in the application environment of the identity module. The DRM application can be preprogrammed into the application environment, or securely downloaded from a trusted party associated with the identity module. The invention also relates to a distributed DRM module, with communication between distributed DRM agents (125, 135) based on usage-device specific key information.

The apparatus includes a source, a receiver, an authorized security device such as a conditional access module (CAM) for decrypting authorized content, an output device for outputting content and a backend for managing accounts and system operations. One aspect of this invention provides a mechanism for providing secured content on a medium such as a DVD optical disc. These devices may verify that there is authorization to play the secured content, add watermarks to the secured content, convert the secured content to a displayable form and provide a means for preventing output of the secured content.

A method and apparatus for enabling use of multiple digital rights management scenarios (DRM). Unencrypted data representing digital content is examined to identify at least segments of content for encryption. The identified segments of content are duplicated and then encrypted using a first encryption method associated with a first DRM to produce first encrypted segments. Duplicates are encrypted using a second encryption method associated with a second DRM to produce second encrypted segments. A set of pointers are generated that point to the first and second encrypted segments content. A file is then created containing first and second encrypted segments of content, pointers and unencrypted content along with DRM rights data to produce a selectively encrypted multiple DRM enabled file.

<heading lvl="0">Abstract of Disclosure< / heading> Before use, a population of tamper-resistant cryptographic enforcement devices is partitioned into groups and issued one or more group keys. Each tamper-resistant device contains multiple computational units to control access to digital content. One of the computational units within each tamper-resistant device communicates with another of the computational units acting as an interface control processor, and serves to protect the contents of a nonvolatile memory from unauthorized access or modification by other portions of the tamper-resistant device, while performing cryptographic computations using the memory contents. Content providers enforce viewing privileges by transmitting encrypted rights keys to a large number of recipient devices. These recipient devices process received messages using the protected processing environment and memory space of the secure unit. The processing result depends on whether the recipient device was specified by the content provider as authorized to view some encrypted digital content. Authorized recipient devices can use the processing result in decrypting the content, while unauthorized devices cannot decrypt the content. A related aspect of the invention provides for securing computational units and controlling attacks. For example, updates to the nonvolatile memory, including program updates, are supported and protected via a cryptographic unlocking and validation process in the secure unit, which can include digital signature verification.
