3940 results about "Digital content" patented technology

Digital content is any content that exists in the form of digital data. Also known as digital media, digital content is stored on digital or analog storage in specific formats. Forms of digital content include information that is digitally broadcast, streamed, or contained in computer files. Viewed narrowly, digital content includes popular media types, while a broader approach considers any type of digital information (e. g. digitally updated weather forecasts, GPS maps, and so on) as digital content.

Secure electronic content distribution on CDS and DVDs

A method to delivery encrypted digital content to a end user system for playing the content comprising the steps of: reading from a computer readable medium metadata which has previously associated with the content. A user selects from the metadata associated content to decrypt and the end user system establishes a secure connection with an authorization authority for decrypting the content. The end user system receives a secure container containing the decrypting key for decrypting at least part of the previously encrypted content as permitted. The system creates a secure container using the encrypting key from a clearing house, wherein the secure container has an encrypting key therein from the end user system; transferring the secure container to the clearing house for authentication of permission to decrypt the content. The system receives from the clearing house, a secure container encrypted using the encrypting key of the end user system containing the decrypting key for decrypting at least part of the previously encrypted content stored on the computer readable medium as permitted; and playing at least part of the previously encrypted content by decrypting the secure container using the encrypting key of the end user system to access the decrypting key for decrypting at least part of the encrypted content.

System and embedded license control mechanism for the creation and distribution of digital content files and enforcement of licensed use of the digital content files

A digital content file including a license control mechanism controlling the licensed use of digital content and a system and method for distributing licensable digital content files and licenses. A digital content file includes a digital content, which may be executable code or data, an embedded file access control mechanism and a dynamic license database associated with the file access mechanism for storing license information used by the file access control mechanism in controlling use of the digital content. The file access control mechanism includes a license monitor and control mechanism communicating with the dynamic license database and controlling use of the digital content and a license control utility providing communications between a user system and an external system to communicate license definition information and includes a graphical user interface. License information may be stored initially in the dynamic license database or provided from an external system. The system allows the distribution of digital content files and the acquisition of licenses with seamless transaction processing through an order processing system generating an order identification and authorization for a license and a product configuration and order database containing license management databases associated with the digital content files and containing license information to be transmitted to a user system upon receipt of an order identifier. The product configuration and order database also generates a license record for each transaction.

System and method for controlling access rights to and security of digital content in a distributed information system, e.g., Internet

A system and method for limiting access to and preventing unauthorized use of an owner's digital content stored in an information network and available to clients under authorized conditions. The network includes at least one server coupled to a storage device for storing the limited access digital content encrypted using a random-generated key, known as a Document Encryption Key (DEK). The DEK is further encrypted with the server's public key, using a public/private key pair algorithm and placed in a digital container stored in a storage device and including as a part of the meta-information which is in the container. The client's workstation is coupled to the server for acquiring the limited access digital content under the authorized condition. A Trusted Information Handler (TIH) is validated by the server after the handler provides a data signature and type of signing algorithm to transaction data descriptive of the purchase agreement between the client and the owner. After the handler has authenticated, the server decrypts the encrypted DEK with its private key and re-encrypts the DEK with the handler's public key ensuring that only the information handler can process the information. The encrypted DEK is further encrypted with the client's public key personalizing the digital content to the client. The client's program decrypts the DEK with his private key and passes it along with the encrypted content to the handler which decrypts the DEK with his private key and proceeds to decrypt the content for displaying to the client.

Method and apparatus for scheduling presentation of digital content on a personal communication device

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. The software scheduling agent compares the contextual digital content profile for each item of digital content to the contextual user profile for each user to determine which digital content should be offered for presentation to each user. The comparison and determination of which items of digital content should be offered for presentation to which users is performed by a process of constrained random variation. After the software scheduling agent determines which items of digital content would most likely be relevant or interesting to the user, the digital content is transmitted, either in whole or in part, at predetermined times over the communication network to the appropriate client devices. The digital content is then stored, either in whole or in part, in cache memory on the client device until an appropriate time when the digital content is digitally packaged and presented to particular users over those user's client devices.
