2. Description of the Related Art In order to protect property and information (mainly documents) from others, a protection method by a mechanical lock and a key using a lock from the ancient times to the present, and modern technology have been added. There is a protection method using an electronic lock.

In computer devices and terminal devices connected to communication lines, passwords for restricting those who access them to certain qualifications in order to protect data stored in a database and protect personal information. Is often provided. A password is composed of a character string with a fixed number of digits, and in many cases, discrimination is provided in the contents of access to data according to the combination. However, the simplest and most common example is a four-digit password (password). There are cash dispensers that allow you to deposit and withdraw personal deposits, and in a slightly more complex example, there are security codes over the Internet and personal computer communications. Furthermore, in important facilities (for example, computer rooms) and buildings, there are cases in which palm print collation and pupil (retina) collation are performed in order to restrict persons entering the facilities.

[0004]

The above-described protection by locking, protection of data, and restriction of access to facilities are nothing less than restrictions on access (access) to those that store property, data, and the like. Person, data controller,
It restricts (prohibits) access to members other than those who have access rights to the use of safes, databases, or facilities by network members, facility employees, etc., and permits access to qualified persons.

[0005] The permission / non-permission of the use of equipment and data depending on the presence or absence of the access right can be applied to, for example, the use permission of a mobile phone which has become popular in recent years. In the mobile phone example, you can not have access to prevent use by others in the case of the misplaced, the restriction of the use of in the family (for example, a particular program is to underage children (for example, Q ² dial),
It can also be used to limit the use of company mobile phones. In the case of mobile phones, a security lock is often provided as an option for the purpose of not being used by anyone other than the user (ie, not being accessed). This is equivalent to access restriction by password.

In the prior art, the above access right is usually set by locking or setting a password as described above. In a special case, the collation of the palm print or the pupil is performed.
In the case of locking, there is a problem that it is easy to make a duplicate key, and it is possible to destroy it by physical external force. (B) In the case of a password, access is easy if the password is stolen, and the number of digits is about 4 digits There are many cases where it is easy to decipher by trial and error, and it is easy to forget, so there are many cases where the date of birth and telephone number are used as a password, which also makes it easier to decipher, so to improve this point There is a problem that if you increase the number of digits or increase the number of input steps, you can not remember it and eventually have to rely on the memo, there is a possibility that you can access the one that obtained the memo, and furthermore, any encryption However, there is a problem that the decryption can be finally performed. (C) The method of acquiring the access right by comparing the palm print and the pupil described above is an application of the image recognition technology, and there is no match between the palm print and the pupil of another person. The fact that it is expensive and does not spread except for special facilities, for example, it is virtually impossible to restrict access to cheap and small mobile phones instead of security locks. is there.

[0007] On the other hand, image input has conventionally been performed using a special camera or scanner. In recent years, however, digital cameras, which are popular products that have been remarkably popularized / developed, are used not only as electrophotographic machines but also as image input devices.

The judging means 1122 compares the degree of coincidence with the threshold value, and when the value is equal to or larger than the threshold value, judges the coincidence and shifts to P3. When the degree is less than the threshold value, shifts to P11 (P2).

After it is determined in P2 that there is a match,
The judging means 1121 checks whether the path image corresponding to the matched matching feature data satisfies the access condition (FIG. 8), and if so, permits the access (transmission) and waits for the protocol confirmation. The call is started, and if not satisfied, the process proceeds to P11 (P3, P4). In the case of reception, a call signal is sent to the other party (sender) until access right determination is completed (P5), and when a call button is pressed, a pass image image of a collation candidate is captured and passed through the image input system 10. Is temporarily stored in the RAM 22 (or DRAM), the feature extracting means 113 is activated to perform a feature data extraction process, and the registration list 711 (or 711 ′) of the flash memory 71 is searched, and the feature data and other data are retrieved. The registration information (priority and the like) is read and temporarily stored in the RAM 22 (or DRAM) (P

When the extraction of the characteristic data is completed in P7, the collating means 1121 is started, and the extracted characteristic data and RAM are extracted.
The matching characteristic data temporarily stored in the storage unit 22 is compared, the degree of coincidence (or similarity) is converted into a numerical value, and is passed to the determination unit 1122. The judging means 1122 compares the degree of coincidence with the threshold value, and when the value is equal to or larger than the threshold value, judges the coincidence and shifts to P8, and when less than the threshold value, shifts to P10 (P7). After the matching is determined in the above P7, the determining means 1121 further checks whether the path data of the matched matching feature data satisfies an access condition (FIG. 8), and if so, accesses (receives). Is permitted, transmission of the call signal is stopped, reception processing is performed, and a telephone call is started. If the call is not satisfied, the process proceeds to P10 (P8, P9).

If the collation results do not match in the above P2 and P7, or if the conditions are not satisfied in P3 and P8, the transmission preparation is interrupted (or the line connection is disconnected) (P10).
