Streamlined digital rights management
10162943 · 2018-12-25 · ·

A streamlined workflow for digital rights management (DRM) licensing for content such as media assets is achieved via an authentication server establishing an authenticated session that is referenced by other processes, whereby a content grant may include a key to desired encrypted content with a portion of the content or content meta-data. The authentication server verifies the user's identity and provides a session grant including a session security mechanism, such as a token, session key, or negotiated secret. The session grant may be used to obtain a content authorization from a content router. The content authorization includes an address at which the content may be found and may be decorated with security mechanisms. The session grant and/or content authorization may include an entitlement record reflecting the user's entitlements to access content. The session grant and/or content authorization may be used to obtain a content grant from a content server.

20180365389 · 2018-12-20 ·

The present invention provides a method for securing a client's access to a DRM agent's services. The method comprising, by the DRM agent, the steps of: receiving a get-token request, applying a function to generate a decryption request identifier Request ID and a token value Token, returning Request ID and Token to the client, inserting, into a hash table of token values with get-token requests identifiers as keys, a record comprising the token value Token associated to the key Request ID, receiving a decryption request comprising Request ID, a multimedia content encrypted chunk and a digest of the encrypted chunk, retrieve Token from hash table based on Request ID, processing digest using a public key and Token, checking match between the processed digest and the at least part of the encrypted chunk and, only in case of match: decrypting the encrypted chunk and returning the decrypted chunk to the client.

Context Aware Content Distribution

Described herein are systems and methods for context aware content distribution. Content such as e-books, presentations, audio, video, applications, and so forth may be distributed to user devices after establishing a trust relationship. An invitation to provide content may be sent to a user device based on the context of the user device, such as proximity to pre-determined devices, location, and so forth. Upon acceptance of the invitation to opt-in to receiving content, a trust relationship may be established which provides for the transfer of content to the user device.

Controlling Use of Shared Content Items Based on Client Device

User accounts can be linked together to form a group of linked user accounts that can access content items assigned to the other user accounts in the group. A user can download content items assigned to their user account, as well as shared content items assigned to one of the other user accounts in the group of linked user accounts. Use of shared content items can be restricted to client devices running specified versions of an operating system. The key ID tagged to a shared content item can be altered such that the key ID no longer correctly identifies the corresponding DRM key that enables use of the shared content item. Client devices authorized to use shared content items can be configured to recognize that a content item is a shared content item and generate the original key ID form the altered key ID.

Method of enabling digital music content to be downloaded to and used on a portable wireless computing device

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.

DIGITAL RIGHTS MANAGEMENT (DRM) METHOD AND SYSTEM FOR INTELLIGENT OPERATING SYSTEM

A digital rights management (DRM) method for an intelligent operating system comprises: acquiring a play list of media data to be played and encrypted media data; inquiring and acquiring one or more DRM application modules, wherein the DRM application module contains an identifier of a trusted application module; requesting DRM authorization by the DRM application module from a DRM server, judging a content permission and acquiring an encrypted content encryption key (ECEK) and transmitting the ECEK to a TEE; after judging that the content permission is legitimate; decrypting the ECEK acquired by the trusted application module which is in the TEE and corresponds to the trusted application module identifier to acquire a content encryption key (CEK), and decrypting the encrypted media data by using the CEK; and storing the decrypted media data in a security cache region for decoding and outputting.

Software-Enabled Remote Licensing and Provisioning

Described herein are systems and methods for providing software provisioning of functionality in a wireless communications device. Software-enabling functionality may include systems for granting a license to intellectual property or other pre-embedded functionality within a device. Communications to and from the device may be used to send or receive activation messages and/or licensing messages. Network capabilities may be provisioned using activation messages sent over the network. Activation messages may be sent in-band or out-of-band, for a device connected to the Internet and/or a mobile operator core network. Licenses may be required for any functions or intellectual property present on a given device. Activation may enable logical modules of a system-on-chip (SOC), functions of a software-defined radio (SDR), baseband, or DSP core. The disclosed systems and methods could thereby provide a new, flexible paradigm, namely, Silicon as a Service (SaaS).

In a method for enabling support for backwards compatibility in a User Domain, in one of a Rights Issuer (RI) and a Local Rights Manager (LRM), a Rights Object Encryption Key (REK) and encrypted REK are received from an entity that generated a User Domain Authorization for the one of the RI and the LRM and the REK is used to generate a User Domain Rights Object (RO) that includes the User Domain Authorization and the encrypted REK.

Digital rights management for HTTP-based media streaming

Techniques and mechanisms described herein facilitate the management of digital rights for media content item presentation. According to various embodiments, a request for a content decryption key may be received at a media application implemented at a computing device. The request may be transmitted by a media content player implemented at the computing device. The request may be transmitted in accordance with a designated key exchange protocol. A license for an encrypted media content item corresponding with the requested content decryption key may be identified at the media application. Based on information included in the license, encrypted key material may be decrypted to create the requested content decryption key via a processor at the computing device. The requested content decryption key may be provided to the media content player.

SYSTEM AND METHOD FOR TARGETED MESSAGING, WORKFLOW MANAGEMENT, AND DIGITAL RIGHTS MANAGEMENT FOR GEOFEEDS

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.
