An information processing device receives a stream for outputting image information from another information processing device by using wireless communication, the information processing device including a wireless communication unit and a control unit. The wireless communication unit performs communication to exchange capability information regarding the information processing device and capability information regarding the other information processing device with the other information processing device. The control unit performs control in a manner that multi-reception diversity of the stream related to the other information processing device is set based on the capability information regarding the other information processing device and a use of the information processing device.

Personal Digital Server (PDS) is a unique computer application for the storage, updating, management and sharing of all types of digital media files, including audio, video, images and documents, irrespective of their format. PDS provides users with a single location to store and access, both locally and remotely, all of their digital media. It also provides the user total control of the overall management of these assets.

An improved method and system for digital rights management is described.

A method, system, and computer program product for controlling consumption of a distributed network service in accordance with rights expression information associated with the distributed network service and specifying a manner of use of the distributed network service, including interpreting the rights expression information associated with the distributed network service, the rights expression information indicating a manner of use of the distributed network service; and controlling consumption of the distributed network service based on the rights expression information.

Systems and methods for providing secure offline file access utilizing information rights management (IRM) are provided herein. In some embodiments, the method may comprise storing one or more IRM-protected documents in a secure local storage on a user device; storing one or more consumption licenses associated with the one or more IRM-protected documents in the secure local storage on the user device, wherein the one or more consumption licenses is required to access one or more IRM-protected documents; detecting a loss of network connectivity on the user device; writing the one or more consumption licenses to an IRM location in memory on the user device; receiving a request to open a document of the one or more IRM-protected documents; reading the consumption license from the IRM location in memory; and enabling access to the requested IRM-protected document based on the consumption license.

Disclosed is a method of transmitting a data set using encryption, wherein the method comprises the steps of: selecting a first encryption technique, wherein said first encryption technique comprises a first encryption algorithm for encrypting plain data into cipher data, and a first decryption algorithm for on provision of a specific key, decrypting cipher data and reproduce plain data; encrypting the first data package comprising plain data, using a first encryption program implementing the first encryption algorithm of said first encryption technique, creating a first encrypted data package comprising cipher data; obtaining a first decryption program; and transmitting said first decryption program and said first encrypted data package to a receiver, wherein the first decryption, upon provision of the specific key and the first encrypted data package, will decrypt the cipher data in the first encrypted data package and reproduce the plain data of the first data package.

A digital content distribution system uses a Digital Rights Management Controller that performs a set of arbitrary tests against the transfer request from one user to another such as user A to user B. Assuming these tests are successful, the DRM sends an encryption key to transferring user A. This encryption key E is taken from a table of encryption key/hash pairs which have been provided to the DRM Controller by an external authority such as the content rights holder. User A encrypts the content using they key provided by the DRM controller and then optionally calculates a hash over the encrypted form of the content E(X) and returns this value to the DRM Controller. On checking the returned hash against the hash from the table the DRM controller knows that user A does indeed have the digital content X in good condition. The DRM Controller then instructs both users A and B that the transfer may proceed. The encrypted form of the content E(X) is transferred from A to B. Once the content transfer has completed B ensures that the received content has been physically written to non-volatile storage (to account for crashes etc. during the next step). B then calculates a hash over the received content and returns this value to the DRM Controller. If this value matches the value previously given then the transfer has been successful and the DRM Controller updates whatever central records are appropriate, while also returning a decrypt key to B to allow it to decrypt the content.

Methods and apparatus for control of data and content protection mechanisms across a network using a download delivery paradigm. In one embodiment, conditional access (CA), digital rights management (DRM), and trusted domain (TD) security policies are delivered, configured and enforced with respect to consumer premises equipment (CPE) within a cable television network. A trusted domain is established within the user's premises within which content access, distribution, and reproduction can be controlled remotely by the network operator. The content may be distributed to secure or non-secure output domains consistent with the security policies enforced by secure CA, DRM, and TD clients running within the trusted domain. Legacy and retail CPE models are also supported. A network security architecture comprising an authentication proxy (AP), provisioning system (MPS), and conditional access system (CAS) is also disclosed, which can interface with a trusted authority (TA) for cryptographic element management and CPE/user device authentication.

The disclosure relates to systems and methods for targeted messaging, workflow management, and digital rights management for geofeeds, including content that is related to geographically definable locations and aggregated from a plurality of social media or other content providers. The system may facilitate targeted messaging to users who create content. The targeted messaging may be based on the content (or location related to the content) such as a request for additional information or a promotional message. The system may generate workflows that allow management of the content with respect to operational processes of an entity that wishes to use the content and facilitates the management of usage rights related to the content as well as payments related to such usage rights. For example, the system may store whether content requires permission to use the content and/or whether such permission was obtained and facilitates payment.

A frequency domain resource configuration method and apparatus, the method including obtaining, by a base station, a first frequency hopping parameter set of UE in N sub-bands, where the N sub-bands have a mapping relationship with a frequency hopping pattern that is indicated by the first frequency hopping parameter set, where the sub-band is a length of consecutive frequency domain resources in a system bandwidth, and where N1, and further including sending, by the base station, first configuration information to the UE, where the first configuration information includes sub-band identifiers of the N sub-bands and the first frequency hopping parameter set.
