INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING METHOD, AND PROGRAM

摘要

The present disclosure realizes a structure that can unify the management of the storage block for the encryption key to be used in decrypting encrypted content stored in a memory card. This structure includes: an information processing apparatus that stores content into an information storage device such as a memory card including an access allowed block based on an access right check made on each block, and uses the content; a content usage managing server that provides content usage permission information to the information processing apparatus; and a content correspondence information providing server that provides the encryption key to be used in decrypting the encrypted content stored in the information storage device. The content usage managing server determines the block for storing the encryption key andnotifies the content correspondence information providing server of a block identifier that is the identifier of the determined block, and the content correspondence information providing server performs a process to write the encryption key into the block corresponding to the received block identifier.
