DIGITAL RIGHTS MANAGEMENT USER DATA TRANSFER FROM ONE TERMINAL TO ANOTHER

摘要

A method, device, and system use a transfer module that is distributed and used in a controlled manner. This transfer module has sufficient access rights to de­crypt and re-encrypt content to perform the unbinding and binding operations needed to transfer content from one terminal to another. Assuming a back-up copy of relevant data is kept by the user, the back-up copy is encrypted with a key of a trusted party. The encrypted data can be transferred to a new device. The corresponding decryption key is transferred from the trusted party to the new device along with the transfer module.
