User authentication device, user authentication method

Abstract

The invention provides a user authentication device and a user authentication program. The user authentication device holds biological information registered for each user and holds user information that is a plurality of kinds of attribute information made correspond to each user. Using the plurality of kinds of attribute information included in the held user information, the user authentication device predicts, on a per-user basis, the possibility that the user requests authentication, and calculates its prediction value. When receiving biological information for an authentication request, the user authentication device compares the received biological information with the biological information of a plurality of users determined by the calculated prediction values and determines, based on the comparison result, whether to authenticate a person who has input the received biological information as a user.

Description

technical field [0001] The invention relates to a user authentication device and a user authentication method. Background technique [0002] Conventionally, biometric authentication for authenticating individuals by using biometric information (for example, fingerprints, vein patterns of palms, irises of eyes, etc.) that is difficult to forge and unique to individuals has been popularized. [0003] For example, in the entry management in a facility using biometric authentication, only when the biometric information received from the person wishing to enter the facility matches the biometric information registered in advance as a user, the person wishing to enter the facility is authenticated as a user. Users who are allowed to enter the facility are allowed to enter the facility. [0004] Here, the biometric authentication method is roughly classified into two types of "1:1 authentication" and "1:N authentication". "1:1 authentication" refers to receiving identification in...

Problems solved by technology

[0013] However, since the above-mentioned technique of sequentially checking biometric information with higher priority focuses on only one behavior pattern and attaches priority, there is a problem that efficient authentication cannot always be realized.

[0014] That is, the behavior pattern of each individual is not limited by only one element, but changes according to multiple elements such as time zone, day of the week, and change of working hours. The problem that it is not necessarily possible to achieve efficient authentication

[0015] In addition, the technique using a cache memory caches biometric information based on predetermined information, so it cannot cope with individual behavior patterns that vary according to multiple factors, and there is a problem that efficient authentication cannot always be realized.
