In general, a door lock (or security authentication system) device is a device for restricting access to a general building, a home or a specific area, or restricting access to the system to only authorized persons for protecting the system.

For example, a door lock system is used to control outsiders' access in public places where security is required, such as research institutes, corporations or government agencies. A good example is the use of a security card with an authentication key stored therein, such as a smart card with a chip containing information about the user and information that allows security authentication.

However, such a security card is inconvenient to carry, there is a high risk of loss, when there is a change in the user's identity there was a need to replace a new security card every time.

In recent years, efforts have been made to replace the function of the security card by using a mobile phone which has become a necessity as well as its function has been dramatically improved according to the ease of portability and the development and utilization of various contents. For example, it is possible to implement a security authentication system without a separate security card through a communication method using Bluetooth technology, and to implement a security authentication system by assigning a password using a phone number of a mobile phone.

However, since they are implemented only through authentication of a single terminal, there is a continuous problem that high reliability is not provided because there is no countermeasure in case of any terminal loss or theft due to password exposure.

In addition, fingerprint, hand, authentication, blood vessel, face, iris, and narrators are gaining popularity in the field of computer / network security and access control in the rapidly increasing use of computers as a means of transmitting information technology in recent years. Major biometric technologies, such as certification, have emerged, and these technologies are being used as reference materials for export strategies, R & D plans and policies of industry, research institutes and policy institutes. Furthermore, scientifically proven that the body of a living individual is the only security tool, and furthermore, since the control decision unit that determines, authenticates, and controls the security tool is an individual human being, the biometric technology is spotlighted as a unique security authentication means. have.

Zadeh of the University of California, California, to deal with fuzzy quantities that are difficult to solve with probability theory. After the publication of the paper, “Fuzzy Sets,” the system was developed systematically. Fuzzy Set's meaning is different from the classical set theory.

In other words, the classical set theory targets definite ideas such as "1, 0" or "YES, NO", and fuzzy set theory is ambiguous, such as "not 1 or 0" or "close to 1". It is a set theory targeting.

Ambiguity, which is the object of such a fuzzy set, is an essential element for humans.In dialogue, which is the only means of information in human society, rather than a definite expression such as YES or NO, it is more like 'complete YES' or 'YES'. Ambiguous expressions such as are frequently used. Therefore, the object of information has important value not only in definite ideas but also in indefinite ideas, and the fuzzy theory is to process such indeterminate information.
