APPARATUS AND METHODS FOR DATA TRANSFER BETEWEEN A PLURALITY OF USER DEVICES

摘要

Methods and apparatus for transferring data (such as for example media or other content) between devices while maintaining protection of the content. In one embodiment, a first user device causes a network entity to generate a shared encryption key for a second user device which is to receive content. In this manner, when the content (which has been encrypted with a key that is specific to the first device) is re-encrypted using the shared key, then transferred to the second device, the second device also obtains the shared key and uses it to decrypt the content, then the second device re-encrpyts the content with a key that is specific to the second device for storage thereon. For example, within a premises network the entire contents of a first digital video recorder (DVR) may be transferred to a replacement DVR.

主权项

1. A method of providing content from a first subscriber device to a second subscriber device, the content being associated to the first subscriber device, and the method comprising:
based at least on the occurrence of a triggering event, requesting a transfer security element for the transfer of the content from the first to the second subscriber device; receiving the transfer security element; decrypting the content using a first security element which is specific to the first subscriber device; re-encrypting the content using the transfer security element; and transferring the content to the second subscriber device.
