Abstract:
1. An information recording apparatus for recording information in one or more storage devices for storing information, the apparatus comprising: a key storage unit configured to store a storage device key for encoding relating each of the one or more storage devices; a first generator unit configured to generate a storage device key which corresponds to a storage device specified in the one or more storage devices and store the device key in the key storage unit in the case where a content storing command has been input; a second generator unit configured to generate a title key which corresponds to input content; a first encoder unit configured to encode the title key by using the generated storage device key and store the encoded title key; a second encoder unit configured to encode the input content by using the title key and store the encoded content in the specified storage device; a generator unit configured to generate a folder for storing the input content in the specific storage device and generate a folder key which corresponds to the folder; a third encoder unit configured to encode the folder key by using the generated storage device key and store the encoded folder key; a fourth encoder unit configured to encode the title key by using the folder key and store the encoded title key; and a storing unit configured to store the encoded content in the generated folder.
