Abstract:
Various embodiments of a system and method of digital rights management with authorized device groups are described. Various embodiments may include a system including a digital rights management (DRM) component configured to receive a private key of an authorized device group. In various embodiments, the receipt of the private key of the authorized device group may indicate the system is an authorized member of a group of devices permitted to access content items protected by a common public key associated with the authorized device group. In various embodiments the DRM component may be configured to, for each given content item of multiple content items that are encrypted with different content keys, decrypt an encrypted content key from the given content item with the private key of the authorized device group and decrypt content from the given content item with the decrypted content key.
