Abstract

Technologies for supporting and implementing multiple digital rights management protocols on a client device are described. In some embodiments, the technologies include a client device having an architectural enclave which may function to identify one of a plurality of digital rights management protocols for protecting digital information to be received from a content provider or a sensor. The architectural enclave select a preexisting secure information processing environment (SIPE) to process said digital information, if a preexisting SIPE supporting the DRM protocol is present on the client. If a preexisting SIPE supporting the DRM protocol is not present on the client, the architectural enclave may general a new SIPE that supports the DRM protocol on the client. Transmission of the digital information may then be directed to the selected preexisting SIPE or the new SIPE, as appropriate.

Claims20

Dependent claims

A client device to support a plurality of digital rights management (DRM) protocols, comprising:

a processor;
at least one architectural enclave;
at least one DRM selection database stored within the architectural enclave, the DRM selection database to associate one or more of the plurality of DRM protocols with one or more corresponding DRM selection factors;
and
policy enforcement circuitry to:
compare digital information to the DRM selection factors, the digital information received from at least one of a content provider and a sensor;
identify a first DRM protocol from the plurality of DRM protocols based, at least in part, on a result of the comparison, wherein the first DRM protocol is to protect the received digital information;
and
select a secure information processing environment (SIPE) supporting the first DRM protocol for processing the digital information, wherein the selecting includes:
determining whether a preexisting SIPE supporting the first DRM protocol exists on the client device;
responsive to a determination that a preexisting SIPE supporting the first DRM protocol exists on the client device, selecting the preexisting SIPE supporting the first DRM protocol for processing the digital information;
and
responsive to a determination that a preexisting SIPE supporting the first DRM protocol does not exist on the client device:
creating a new SIPE supporting the first DRM protocol on the client device;
and
selecting the new SIPE for processing the digital information.

13 more elements

At least one non-transitory computer-readable storage medium having instructions stored thereon which, when executed by at least one processor, cause the at least one processor to perform operations for supporting a plurality of digital rights management (DRM) protocols, the operations comprising:

receive digital information from at least one of a content provider and a sensor;
compare the digital information to at least one of a plurality of DRM selection factors, the DRM selection factors associated with the plurality of DRM protocols;
identify a first DRM protocol from the plurality of DRM protocols based, at least in part, on a result of the comparison, wherein the first DRM protocol is to protect the received digital information;
and
select a secure information processing environment (SIPE) supporting the first DRM protocol for processing the digital information, wherein the selecting includes:
determining whether a preexisting SIPE supporting the first DRM protocol exists on a client device;
responsive to a determination that a preexisting SIPE supporting the first DRM protocol exists on the client device, selecting the preexisting SIPE supporting the first DRM protocol for processing the digital information;
and
responsive to a determination that a preexisting SIPE supporting the first DRM protocol does not exist on the client device:
creating a new SIPE supporting the first DRM protocol on the client device;
and
selecting the new SIPE for processing the digital information.
