Abstract
A method of transferring a rights object (RO) and an electronic device are provided. The method includes generating a secure RO by encrypting an RO including usage rights information regarding digital content and transferring the secure RO from a first device to a second device.
Claims5
An electronic device comprising:
- a memory storing computer-readable instructions for causing the electronic device to implement a method of transferring a secure rights object (RO) between the electronic device and an external device;
- and
- a processor which when executing the computer-readable instructions is configured to control the electronic device to implement the method of transferring the secure RO between the electronic device and the external device, the method comprising:
- interfacing, by the electronic device, with the external device that transmits a copy of the secure RO;
- receiving, by the electronic device, the copy of the secure RO from the external device in a first transmission from the external device;
- notifying, by the electronic device, the external device that the receiving of the copy of the secure RO has been completed, wherein the external device removes the secure RO from a memory within the external device in response to the notifying;
- receiving, by the electronic device, a request for decryption of the copy of the secure RO from the external device in a second transmission separate from the first transmission, wherein the request for decryption includes an encryption key used by the external device to generate the secure RO;
- in response to the request for decryption of the secure RO, decrypting, by the electronic device, the secure RO using the encryption key;
- and
- notifying the external device that the decrypting of the secure RO has been completed.
