Abstract: When storing data (D1), spread on a memory (10), into a file storage unit (50), a user ? assigns a meaningful filename-for-user, such as “sales book for April.” Storage control unit (35) converts this “sales book for April” to a meaningless filename-for-storage, such as “RST123.” The correspondence between the two is stored as filename correspondence information for user ? in a correspondence information storage unit (80). A storage processing unit (30) stores the data (D1) with the filename, “RST123.” Whereas when user ? is presented with a list of filenames of the stored files from a filename presentation unit (60), the meaningful filename of “sales book for April” is presented as the filename since a presentation control unit (65) performs reverse conversion of the filename based on the filename correspondence information, the meaningless filename of “RST123” is presented to other users. Security in regard to filenames can thus be secured and inference of the file contents can be prevented.

Abstract: An agent program (12) installed in a terminal device (10) is used to upload data, which are to be stored, to a data storage device (100) via a first network (N1). Data uploaded to a first data storage unit (110) are stored therein as they are. On the other hand, data uploaded to a second data storage unit (120) are transferred, by the function of a data transferring unit (130), to any of external storage sites (210-230) via a second network (N2), and management information, which includes the URL of the storage site that is the transfer destination, is stored into an IC card (11). When the data stored in the data storage unit (120) are required, the management information in the IC card (11) is given to the data transferring unit (130) and the relevant data are forwarded from the storage site that was the transfer destination to the data storage unit (120) and then downloaded to the terminal device (10). The limit of the storage capacity can thereby be overcome and damages due to viruses can be suppressed.

Abstract: It is possible to issue an. IC card storing unique encryption key information in such a manner that re-issuing is enabled and sufficient security can be assured. An IC card provider X delivers an IC card having a group code G(A) to a company A and an IC card having a group code G(B) to a company B. When a company staff ? inputs a unique personal code P(?) and performs initialization, in the IC card, calculation is performed according to a predetermined algorithm using the P(?) and G(A). Data uniquely determined by the calculation is stored as encryption key information K(?) in the IC card. Even if the company staff ? loses the IC card, it is possible to obtain the IC card having the same encryption key information K(?) as before by performing initialization again by using the IC card delivered by the IC card provider X.

Abstract: It is possible to perform encrypted communication between members of a group while assuring a sufficient security compatible with a change of the members. An IC card having the same fixed code F(a) is distributed to all the staffs of company A. When communication is performed between a staff ? and a staff ? belonging to the same project group, ? of the transmission side writes an arbitrary variable code V(1) in the IC card (100a) so as to generate encryption key information K(a1) according to F(a) and V(1) in the IC card and encrypt data D1 by using K(a1). ? of the reception side writes the variable code V(1) received from ? in the IC card (100b) so as to generate encryption key information K(a1). By using this K(a1), the encrypted data D2 received is decrypted to obtain data D3. The fixed code F(a) is different for each of the companies and rewrite-disabled so as to assure security.

Abstract: By limiting a backup object to a particular one, it is possible to reduce the system load and perform effective automatic backup. By using a hard disc device or the like, a first storage unit (40) and a second storage unit (70) are prepared. When the system is started, a spreading and storing unit (30) formed by a device driver spreads an OS program and an application program A on a memory (20).

Abstract: In order to give sufficient evidential admissibility to the content of a contract made online, contractual terms data C that shows a character string of contractual terms is prepared and stored by a processor on the side of a transacting party A. The data C is then transmitted to a processor on the side of a transacting party B, and is stored. A hash value ID2 of the contractual terms data C is calculated by the B-side processor, and a signature Sig2 of the party B is added and transmitted to the A-side processor as formal contractual proposal information. The signature Sig2 is verified by the A-side processor. A coincidence is verified between a hash value ID1 of the data C and the ID2 that has been transmitted. A signature Sig1 of the party A is added to a coinciding hash value ID, and is transmitted to the B-side processor as formal contractual acceptance information.

Abstract: When storing data (D1), spread on a memory (10), into a file storage unit (50), a user ? assigns a meaningful filename-for-user, such as “sales book for April.” Storage control unit (35) converts this “sales book for April” to a meaningless filename-for-storage, such as “RST123.” The correspondence between the two is stored as filename correspondence information for user ? in a correspondence information storage unit (80). A storage processing unit (30) stores the data (D1) with the filename, “RST123.” Whereas when user ? is presented with a list of filenames of the stored files from a filename presentation unit (60), the meaningful filename of “sales book for April” is presented as the filename since a presentation control unit (65) performs reverse conversion of the filename based on the filename correspondence information, the meaningless filename of “RST123” is presented to other users. Security in regard to filenames can thus be secured and inference of the file contents can be prevented.

Abstract: When a user, who has logged onto an information processing apparatus (100), executes a logoff procedure, a saving unit (160) executes the following processes. Firstly, from among the files residing in a data storage unit (110), any files that are recognized as requiring a security protection and hence are to be saved are copied into an external storage device (300) via a network (200), and the original files in the data storage unit (110) are then deleted. At this moment, the address of the copy destination is stored, as management information, into a portable information recording medium (400) possessed by the user. When the user logs onto the information processing apparatus (100) again, a restoring unit (170) restores, based on the management information stored in the portable information recording medium (400), the files saved in the external storage device (300) into the data storage unit (110).
