Secure element-centric digital rights management

摘要

The examples provided herein relate to digital rights management keys that allow for the presentation of content on output devices of a content presentation device. The examples describe subscriber-specific digital rights management keys that are provided to a subscriber by a mobile network operator instead of a device manufacturer. The digital rights management keys are associated with the subscriber account maintained by the mobile network operator. As a result, the mobile network operator provides the capability to transfer the digital rights management keys between multiple devices because the digital rights management keys are subscriber-specific instead of device-specific.

主权项

1. A method, comprising:
receiving, by a processor of a mobile device, a request to present content on an output device of the mobile device; determining that the requested content requires a subscriber-specific security key to be presented on the output device, wherein the subscriber-specific security key is a digital rights management key assigned by a mobile network operator to a subscriber of the mobile device and is associated with the requested content; accessing, by a secure element processor, a secure element embedded within the mobile device that includes a secure element memory of the mobile device having stored therein a plurality of subscriber-specific security keys, wherein the secure element processor operates independently from the processor of the mobile device to provide access to secured or personal information requested by the processor of the mobile device from the secure element memory, wherein the secure element memory is protected by one or more security layers implementing encryption techniques to restrict access to the secure element memory to the secure element processor, and wherein the secure element memory further includes an application that when executed by the secure element processor, obtains the subscriber-specific security key or secured information for the processor of the mobile device; analyzing, by the secure element processor, the plurality of subscriber-specific security keys stored in the secure element memory; retrieving, based on the results of the analysis, the subscriber-specific security key of the plurality of subscriber-specific security keys that is associated with the requested content; determining, by the processor of the mobile device and based on the subscriber-specific security key, a content decryption key; and presenting, by a media player application executed by the processor of the mobile device and using the content decryption key, the requested content through the output device of the mobile device.
