Abstract: Systems and methods are provided for digital rights management of licensed media content. Client library components and server library components provide digital rights management services. A client-side hosting application accesses client library functionality through invocation of client application programming interfaces (APIs). A server-side hosting application accesses server library functionality through invocation of server APIs. Licenses for specific media content can be requested and issued, and appropriately licensed media content can be played. Client and server library components can function essentially absent direct communication, such as that employing a transport layer. Communications between client and server library components can be carried by the hosting applications.

Abstract: There is a performing of digital rights management (DRM), operable in an offline mode with respect to a communications network. The performing includes identifying a stored rights object associated with a stored asset. The stored rights object includes reporting duration information associated with the stored asset. The performing also includes determining, utilizing a processor, whether a transmission of an early status message is a successful communication based on an early status message determination. If a failure in communicating the early status message is determined, utilizing the stored asset. The performing may also include transmitting an early status message and/or later status message after identifying the stored rights object. There is also a performing of digital rights management (DRM) associated with a DRM system and operable in an offline mode with respect to a communications network. There are also client devices, communicating systems, computer readable mediums and protocols.

Abstract: Methods and devices for clock roll-back detection in non-secure mobile platforms are disclosed. A first time is received from a secure time source. The first time is recorded as a last known good time (“LKGT”) in secure storage on the mobile device. The LKGT is advanced and stored whenever a triggering event occurs. The mobile device receives a second time from the secure time source and records the second time as a subsequent stored LKGT in secure storage.

Abstract: A Service Key Delivery (SKD) system for delivering a service keys to client devices in a communications network. The delivered service keys are operable to be used to decrypt an encrypted key operable to be used to decrypt an encrypted digital content. The SKD system includes a data input interface for receiving a distribution time frame for the keys and a listing of client device identifications. The SKD system also includes a scheduling module to partition at least part of the distribution time frame into a number of time slots in which the number may be based on a variety of factors. The scheduling module assigns the time slots in the partitioned part of the distribution time frame to the client devices based on the identifications in the listing. The SKD system also includes a message generator configured to send key delivery messages to the client devices.

Abstract: A method is provided for enrolling and authenticating an attendee of an event or activity so that content can be delivered to a mobile device associated with the attendee. The method includes receiving an identifier of a mobile communication device associated with an authorized attendee while the attendee and the mobile communication device are in a venue at which the event or activity takes place. The mobile communication device is registered by storing the identifier in a database of authorized attendees who have entered the venue. Entitlement credentials are communicated to the mobile device that are to be further communicated from the mobile device to a content server when requesting event or activity related content therefrom.
