A computer implemented system and method of sharing files between a link sharer and a link recipient over a network. The method comprises generating, in response to a request by a link sharer, a file sharing link to a file set, where the link does not provide a link recipient the ability to modify the contents of the linked file set. In response to receiving an indication that the generated link has been activated by a link recipient, displaying a representation of the linked file set with a display element configured to send a request for modification rights to the linked file set when activated by the link recipient. In response to receiving the request for modification rights, either automatically granting modification rights to the linked file set or sending notice to the link sharer indicating that the link recipient is requesting modification rights to the linked file set.

A method to provide negotiation control to data such that a person or entity can negotiate the use of data gathered beyond what is needed for a particular use by a third party transaction.

A system and method of encrypting digital content in a digital container and securely locking the encrypted content to a particular user and/or computer or other computing device is provided. The system uses a token-based authentication and authorization procedure and involves the use of an authentication/authorization server. This system provides a high level of encryption security equivalent to that provided by public key/asymmetric cryptography without the complexity and expense of the associated PKI infrastructure. The system enjoys the simplicity and ease of use of single key/symmetric cryptography without the risk inherent in passing unsecured hidden keys. The secured digital container when locked to a user or user's device may not open or permit access to the contents if the digital container is transferred to another user's device. The digital container provides a secure technique of distributing electronic content such as videos, text, data, photos, financial data, sales solicitations, or the like.

A system that incorporates teachings of the present disclosure may include, for example, a server having a controller to maintain content rights parameters associated with media content and a user where the content rights parameters include limits to distribution of the media content to a plurality of communication devices associated with the user and where a portion of the plurality of communication devices use different communication protocols from another portion of the plurality of communication devices, monitor for access to the media content by one communication device of the plurality of communication devices of the user, and obtain rights control data that is adapted to allow for presentation of the media content by the one communication device of the user where the rights control data is generated based on the content rights parameters. Other embodiments are disclosed.

Provided are a system and method for media content rights transferal based on protocol for management of media content rights using distributed media rights transaction ledger. One of first gateway node or first node of plurality of nodes, associated with one of first or second initiating participant, respectively, receives request or determine need for media content rights transferal of media content. Associated instance of distributed media rights transaction ledger is traversed, address of one of second node or second gateway node associated with identifier of one of a first or a second receiving participant is determined, initial media content rights transaction is issued, and new media content rights response transaction is received. Accordingly, media content rights transferal transaction is executed. Each instance of distributed media rights transaction ledger is appended with initial media content rights transaction, new media content rights response transaction, and media content rights transferal transaction.

The invention enables digital music content to be downloaded to and used on a portable wireless computing device. An application running on the wireless device has been automatically adapted to parameters associated with the wireless device without end-user input (e.g. the application has been configured in dependence on the device OS and firmware, related bugs, screen size, pixel number, security models, connection handling, memory etc. This application enables an end-user to browse and search music content on a remote server using a wireless network; to download music content from that remote server using the wireless network and to playback and manage that downloaded music content. The application also includes a digital rights management system that enables unlimited legal downloads of different music tracks to the device and also enables any of those tracks stored on the device to be played so long as a subscription service has not terminated.

Systems and methods are for content security may comprise transmitting a request for authorization to access secured content. A content key for the secured content may be received and stored to a restricted region of a memory. A device security module may have access to the restricted region and may decrypt, based on satisfaction of a use condition and using the content key, the secured content. An encryption key associated with a secure media system authorized to access the secured content may be received. The device security module may encrypt, using the encryption key, the secured content and route the secured content to the secure media system.

The invention provide systems and methods for management of digital media objects, comprising first and second client digital data processors (e.g., personal (or private) computers, laptops, dedicated music devices, electronic book readers, and so forth) that are in communications coupling with one or more stores (e.g, dedicated disk drives, flash drives, cloud storage, etc.). At least one digital media object (DMO) or copy thereof is stored in one or more of those stores and is accessible by at least one of the first and second client digital data processors.

Method for automatically distributing, as needed, a user's digital-works and usage-rights to one or more user-devices. A definition of the usage-rights for a digital-work may be stored at one or more locations on a network. A version of said digital-work suitable for a user-device may be provided by one or more locations on said network. When a user who is authorized to utilize said digital-work is active at a user-device, a version of said digital-work and authorization to utilize is automatically transferred when needed to a user-device. The digital-work and authorization may be automatically transferred as needed to any user-device where an authorized user is active. The usage-rights may only be valid for one or more specific users. The usage authorization at each user-device may be less than defined in the full usage-rights maintained on the network. Authorization to utilize said digital-work at a user-device may be extended from time to time by exchanging user-device status across the network. Digital-works are automatically provided as needed to any user-device that an authorized user is using.

Systems and methods for sharing content between devices are disclosed. To request a shared piece of media content, a playback device generates and sends a request to content server. The playback device includes information in the request that indicates the playback capabilities of the device. The content server receives the request and determines the playback capabilities of the playback device from the information in the request. The content server then determines the assets that may be used by the playback device to obtain the media content and generates a top level index file for the playback device that includes information about the determined assets. The top level index file is then sent to the playback device that may then use the top level index file to obtain the media content using the indicated assets.
