Individual authentication method using a recording medium and individual authentication system using a recording medium

Abstract

An individual authentication method using a recording medium and an individual authentication system using a recording medium for facilitating a user to memorize the user information, making it difficult for a third person to set up for the user, reducing the user rejection ratio, and heightening the barier For a third person to set up for the user. User information consisting of at lest one information unit which a user to be registered knows and non-user information consisting of at least one information unitwhich the user dose not know are registered in advance knows on the recording medium for authentication of the user so as to form the registration information When performing authentication, a user candidate user his / her recording medium to indicate the registration information recorded directly or indirectly. The individual authentication method uses such a recording Medium that only when the user candidate selects the user information, the candidate can be authenticated.

Description

technical field [0001] The present invention relates to a personal authentication method using a recording medium and a personal authentication system using the recording medium. Background technique [0002] Password authentication and biometric authentication are known personal authentication methods. [0003] Password authentication is a simple authentication method widely used in the system at present. From the perspective of cognitive psychology, this method can be classified as a method of "recapturing" and "regenerating" meaningless symbolic memory or "semantic memory". Memories do not come from experience, but from memory storage information in the human brain. [0004] However, a well-known problem with ciphers is that for people with short-term memory, especially older people, the regeneration of nonsense symbols without experience or semantic memory is very difficult and prone to errors. In order to avoid this shortcoming, it is common practice to convert simpl...

AI Technical Summary

Problems solved by technology

Therefore, the problem that arises is that when user authentication information is stolen, all authentication media are damaged, and it is very difficult to obtain replacement user information

[0007] In addition, the input device needs to re-read the physiological information

In addition, since the input information changes according to the input / reading conditions, there is a problem of the so-called user rejection rate. When the user rejection rate table is used, the probability of tampering with the user by a third party increases.
