INFORMATION PROCESSING APPARATUS AND METHOD, COMPUTER-READABLE RECORDING MEDIUM, AND EXTERNAL STORAGE MEDIUM
First Claim
1. An information processing apparatus which manages data stored in a connected external storage medium, the information processing apparatus being characterized in comprising:
- a test section which tests whether or not a special format area which is an area for storing secret data exists in the external storage medium;
an access section which accesses the special format area; and
an access inhibiting section which inhibits access to the external storage medium by the access section if it is judged by the test section that the external storage medium does not have the special format area,wherein when the information of the special format area is mounted, the access inhibiting section acquires identification information specific to a special format area to be mounted this time, checks whether or not the special format area corresponds to a special format area which has been already mounted, and inhibits mounting if the special format area does not correspond.

Abstract
There is realized such a method for safely using and storing secret data that electronic copies of the secret data do not flow out of a particular external storage medium. In the present invention, a special format area which cannot be recognized from an ordinary PC is created in an external storage medium, and secret data is stored therein. By making a configuration in which a function of mounting the special format area is provided, and secret data in the special format area is edited and used on a work OS on which network access is inhibited and writing to a secondary storage device is inhibited, the destination of storing the secret data after it is used is limited to the special format area on the external storage medium so that outflow of the secret data from the external storage medium is prevented.
