ABSTRACT:
According to one embodiment, a content recording apparatus is connected with a permission server that permits recording of content through a network. The content recording apparatus reads content encrypted based on a first encryption scheme and binding information from a disposed second recording medium, and uses the binding information to decode the read content encrypted based on the first encryption scheme. The content recording apparatus uses the permission server to authenticate permission of recording of the content, encrypts the decoded content based on a second encryption scheme when recording of the content is permitted, and records the content encrypted based on the second encryption scheme and the binding information in the first recording medium.
