  • Patent number: 8856868
    Abstract: The present application relates to a technique applied to a system for performing authentication of a user by a one-to-one verification method by using an ID and biometric information of the user. When the user registers the ID and reference biometric information in a service providing system, the information is transmitted from the relevant service providing system to a management server. Then, in the management server, ID management by the reference biometric information is performed, and when the user inputs a wrong ID at the time of verification before the relevant service providing system starts to provide a service, a correct ID of the relevant user is found.

  • Patent number: 8242882
    Abstract: A biometric authentication apparatus includes a part to retain first biometric data items extracted from living body parts of a user in correlation with the collation order of the first biometric data items; a part to acquire a second biometric data item from the user, to compare and collate the acquired second biometric data item with the first biometric data items in descending order of their collation priorities based on the collation order, and to determine that the user has been successfully authenticated in response to detecting one of the first biometric data items whose match rate with the second biometric data item exceeds a predetermined value; and a part to change the collation order in response to detecting, from the state of usage of the one of the first biometric data items, that the user has steadied at a change of her/his living body part to use for authentication.

  • Patent number: 7620213
    Abstract: Collation information comprises anatomical information, such as finger print feature information, etc., and identification information. For the identification information, the serial number or equipment description of a device by which the anatomical information is collected, information about a route taken between a collection device and an authentication device or serial number attached to anatomical information collected by a specifying device, etc., is used instead of conventional time information. Then, the entire collation information is encrypted and is transmitted from an anatomical information collecting device to an authentication device via a network.

  • Patent number: 7441181
    Abstract: When predetermined information is input into an input field and an OK button is pressed on a user authentication screen displayed on a monitor screen by a browser at entry time, the input predetermined information, the input predetermined information, the positional information about the input field and the OK button, and the identification information on the user authentication screen are obtained by the input unit and entered in an external storage device through a storage unit. When the authentication screen detection unit detects the user authentication screen by the authentication screen detection unit at input time, the input/press unit automatically inputs the predetermined information read from the external storage device into the position of the input field obtained according to the positional information read from the external storage device through the storage unit, and the position of the OK button is automatically pressed.

  • Publication number: 20080104676
    Abstract: The object of the present invention is to realize a biological authentication system which has a high authentication success rate and a low improper authentication rate and does not inconvenience users. In a server connected to a client, which creates biological data of a user to be authenticated, over a network and performs the authentication determination on the user, user authentication is performed by comparing identification information stored in the client and the identification information of reference biological data if multiple pieces of reference biological data have the degree of agreement with the biological data transmitted from the client beyond a set value.

  • Patent number: 6983061
    Abstract: A system performing secondary verification using only existing apparatuses to accomplish a measure for relief in personal authentication without causing complexity or without increasing cost. The system has a registering apparatus for obtaining data for verification from information inputted using an inputting unit and registering the data. The registering apparatus has a first extracting unit for extracting biometrics characteristic data from the biometrics information obtained by the inputting unit, and registering the biometrics characteristic data as registry biometrics characteristic data for primary verification, and a second extracting unit for extracting data, which is different from the registry biometrics characteristic data, from information inputted using the inputting unit and registering the data as registry data for secondary verification.
