A storage address consisting of a rack number T-DR, a sector number 5-ADR, and an image size S is stored.

Next, the operation of such a ((4) will be explained.

First, a description will be given of the case where the optical disc 19 is used for the first time, that is, the platform on which a file is to be created. For example, one optical disc on which nothing has been written is set in the optical disc device 22.

Then, the CPU 12 turns on the motor (not shown) of the optical disc device 22, making the optical disc 19 ready for use. Then, the CPU 12 determines that nothing is stored on the optical disc 19, and determines that the mode is file creation mode. As a result, the CPU 12 uses the CR'T display device 24 to display [Please input management data such as file set name and file name, security code and fingerprint address, title structure, title range, and table of aliases. ” will be provided.

In response to this guidance, the file creator
Use to set the file set name and file name, creator's secret code, number of users, user's secret code, title structure, title range, and alias. As a result, CPJJ12 uses the fileset name and file name,
The creator's secret code, the number of users, the user's secret code, title structure, title range, and alias are stored in the management data storage area 28a of the magnetic disk 28.

Further, the creator uses the fingerprint input device 32 to sequentially input the fingerprints of the creator and the user. First, the creator's fingerprint is two-dimensionally read by the fingerprint input device 32 and stored in the RAM 36 via the buffer 33 and CPU 31. Next, the CPIJ 31 reads out the creator's fingerprint pattern stored in the RAM 36 and outputs it to the CPU 12. Then, the CPU 12 supplies the creator's fingerprint pattern supplied from the CPU 31 to the optical disk device 22. As a result, the optical disk device 22 stores the supplied fingerprint pattern of the creator on the optical disk 19.

When the storage of this fingerprint pattern is completed, the CPU 12 selects the track number where the fingerprint pattern is recorded, the starting sector,
Storage addresses such as the number of sectors are stored in the management data storage area 28a of the magnetic disk 28 in correspondence with the secret code of the creator.

Next, the fingerprint of the authorized user is read two-dimensionally by the fingerprint input device 32, and the fingerprint is read by the fingerprint input device 32 and sent to the R
It is stored in AM36. Then, the CPU 31 uses the RA
Read out the fingerprint pattern of the authorized user stored in M36,
CPU'U"+2. Then, CPU12 outputs to CP'U"+2.
The fingerprint pattern of the authorized person supplied from U31 is supplied to the optical disk device 22. As a result, the optical disk device 22 records the supplied fingerprint pattern of the authorized user on the optical disk 19.

When the recording of the fingerprint pattern is completed, the CPU 12 selects the track number where the fingerprint pattern is stored, the starting sector,
A storage address such as the number of sectors is stored in the management data storage area 28a of the magnetic disk 28 in correspondence with the confidential code of the authorized user. In addition, the fingerprint patterns of other permitted users and their notes/addresses are also stored in the same manner as described above.

Next, a case will be described in which the optical disc 19 on which the fingerprint pattern is recorded as described above is used. First, the optical disc 19 is set in the optical disc device 22. Then, the CPU 12 turns on the motor (not shown) of the optical disc device 22, making the optical disc 19 ready for use. Then, the CPU 12 determines that the #M secret code and fingerprint pattern are stored on the optical disc 19. As a result, the CPU 12 prompts the user on the CRT display device 24 with the message ``Please enter the secret code and also enter your fingerprint.

In response to this guidance, the user uses the keyboard 23 to set the ls secret code. As a result, the CPU 12 reads the creator's confidential code and the user's confidential code stored in the management data storage area 28a of the magnetic disk 28 corresponding to the optical disk 19, and matches the input confidential code. Perform jinik. As a result of this check, if the input secret code and the creator's secret code match, the fingerprint storage address corresponding to the creator's secret code in the storage area 28a is read out. Then, C.P.
U12 causes the optical disk device 22 to perform reproduction on the optical disk 19 corresponding to the storage address. This results in
The CPU 12 outputs the fingerprint pattern from the optical disk device 22 to the CPU 31.

Next, the CPIJ 31 stores the creator's fingerprint pattern supplied from the CPU 12 in the RAM 36.

At this point, the user's fingerprint is read two-dimensionally with the fingerprint input bag @32 and sent to the R
It is stored in AM36. This causes cpU3't
reads the creator's fingerprint pattern stored in its RAM 36 and outputs it to the transfer circuit 35. Then, the moving circuit 35
outputs various patterns obtained by rotating or translating the creator's fingerprint pattern to the determination circuit 34. Also, CPU
31 is the fingerprint pattern inputted by the fingerprint input device 32.
It reads out from Δ to 136 and outputs it to the determination circuit 34. As a result, the determination circuit 34 determines the degree of similarity between these patterns, and determines whether or not the highest degree of similarity has reached a predetermined value. It is determined whether the fingerprint pattern matches the person's fingerprint pattern. If the judgment result is a match, the match signal from the judgment circuit 34 is output to the CPU 12 via the CPU 31. As a result, the CPU 12 determines the use by the creator and guides the creator to select a process (storage, change, deletion, search).Then, the selected process is executed.

In addition, the CPU'12 checks whether the input secret code matches the creator's confidential code and the user's confidential code stored in the management data storage large area 28a, and the input confidential code. - When the code and the user's secret code match, the fingerprint storage address corresponding to the user's secret code in the storage area 28a is read out.Then, the CPU 1
2 causes the optical disk device 22 to perform reproduction on the optical disk 19 corresponding to the storage address. As a result, C.P.
U12 converts the fingerprint pattern from the optical disk device 22 into CP
Output to U31.

Next, the CPU 31 records the user's fingerprint pattern supplied from the CPU 12 in the RAM 36.

At this time, the user's fingerprint is read two-dimensionally by the fingerprint input device 32, and the user's fingerprint is read by the fingerprint input device 32.
The CPU 31
reads out the user's fingerprint pattern stored in its RAM 36 and outputs it to the movement circuit 35. Then, the moving circuit 35
outputs various patterns obtained by rotating or translating the user's fingerprint pattern to the determination circuit 34. Also, C.P.
U31 reads out the fingerprint pattern inputted by the fingerprint input device 32 from the RAM 36 and outputs it to the determination circuit 34. Thereby, the determination circuit 34 determines the degree of similarity between these patterns, and depending on whether the highest degree of similarity has reached a predetermined value, the input fingerprint pattern or the creator's name stored on the optical disk 19 is determined. Determine whether it matches the fingerprint pattern. If the judgment result is a match, the match signal from the judgment circuit 34 is output to the CPU 12 via the CPU 31. As a result, the CPU 12 determines the use by the user and guides the user to select a process (storage, retrieval). Thereafter, the selected process is executed.

Also, if the secret code and fingerprint do not match,
The CPU 11 provides guidance indicating that processing cannot be executed on the CRT display device 24.

As described above, since the user is identified by comparing the fingerprint, the uniqueness of the fingerprint can be used to reliably identify the user, thereby enhancing security. At the same time, management by the user becomes easier.

In the above embodiment, a secret code and fingerprint information are assigned to each optical disc (file), but the present invention is not limited to this.
It is also possible to search by cabinet or by image information. In the case of each image information, its detailed information and fingerprint information 9F
There is only one address for A so that it is recorded in the corresponding search data.

Furthermore, when comparing fingerprints, the pattern of the fingerprint that has been recorded in advance may be rotated, or the pattern of the fingerprint that has been inserted may be rotated. is stored on the optical disc 1 as is, but the invention is not limited to this, and the data may be compressed and stored.

In addition, although we have described the case where fingerprint information is recorded on an optical disk, the fingerprint information is not limited to this, and may be recorded on a magnetic disk, etc. In this case, as in the case of an optical disk, the storage location or address may be recorded. It is stored in correspondence with

Further, although the fingerprint pattern is identified, the present invention is not limited to this, and identification may be made using a unique pattern on the hand (handprint, palm pattern), the color of the hand, or the like.
