Authentication card, card authentication terminal, card authentication server, and card authentication system

Abstract

The invention relates to an authentication card, a card authentication terminal, a card authentication server and a card authentication system. The operator operating the terminal can easily and accurately determine whether the user of the authentication card is the holder. The card authentication terminal (3) has: an image recording unit (12), which records a base image set composed of a plurality of base images; coefficient information acquisition units (11, 13), which record coefficient information corresponding to each base image The authentication card or the card authentication server connected on the network (5) obtains the coefficient information; and the image processing unit (14), which performs the synthesis processing of the authentication image according to the base image set and the coefficient information, and the authentication image is used for It is judged whether the user of the card is the holder.

Description

technical field [0001] The present invention relates to an authentication card, a card authentication terminal, a card authentication server, and a card authentication system. An authentication card, a card authentication terminal, a card authentication server, and a card authentication system. Background technique [0002] At present, there are many systems as follows: the service provider provides a specified card to a specific user (such as a member, etc.), and when it can be judged (identified) that the card-issuing user is a legal card owner (the real user who accepts the card) In some cases, specific services are provided to card users. As the card used in the above-mentioned services, for example, known security cards, basic resident registration cards adopted in Japan, and the like. In addition, it can also be applied to identity certificates such as driver's licenses and the like. [0003] As one of the cards provided like this, there is a well-known credit card....

Problems solved by technology

However, when using biometric information to determine whether the user is the owner, it is necessary to install a device for authentication based on the biometric information in a store or the like, which causes problems such as installation costs.

[0016] In addition, a method of improving the accuracy of legality judgment and ensuring security by using multiple authentication methods such as signature, password, and biometric information in the legality judgment of the holder is also considered. When using this method, it may increase the authentication burden when shopping with a credit card, thereby destroying the convenience of the credit card
