Patent number: 9009486Abstract: An authentication processing device receives biometric data to be checked from a biometric measuring device; transforms the biometric data that is input from the biometric measuring device by using a checking transformation parameter that is different from a registration transformation parameter; and creates checking biometric data. Then, the authentication processing device performs a differential transformation process on the created checking biometric data by using a differential parameter by which a transformation state transformed by the checking transformation parameter and a transformation state transformed by the registration transformation parameter have the same state. Thereafter, the authentication processing device checks the transformed checking biometric data against the registration biometric data stored in a transformation registration data DB and performs authentication.Type: GrantFiled: September 23, 2011Date of Patent: April 14, 2015Assignee: Fujitsu LimitedInventors: Hironori Yokoi, Toshio Endoh

Patent number: 8310358Abstract: Disclosed is an authentication apparatus easily achieving convenience and high accuracy in authentication. The authentication apparatus has an authentication accuracy simulation section that simulates authentication accuracy and also has a registration information setting section that sets an ID and biometric information input as registration information. The authentication accuracy simulation section uses an ID and biometric information that has been input as registration information by a user at the time of registration and the registered registration information to simulate authentication accuracy with which the user is authenticated. When the authentication accuracy simulated by the authentication accuracy simulation section does not satisfy a predetermined condition, the registration information setting section rejects registration of the ID input as the registration information.Type: GrantFiled: June 24, 2009Date of Patent: November 13, 2012Assignee: Fujitsu LimitedInventors: Masaki Watanabe, Toshio Endoh, Takahiro Aoki, Mitsuaki Fukuda, Soichi Hama, Hironori Yokoi

Patent number: 8266081Abstract: A parameter controlling apparatus calculates similarity variation distribution of different data and that of identical data. The parameter controlling apparatus creates a collation break-off rate function and an error probability function based on the similarity variation distribution of the different data and that of the identical data, respectively, and creates a total collation time function and a total error probability function based on the collation break-off rate function and the error probability function. The parameter controlling apparatus creates a constraint equation based on the total collation time function, the total error probability function, total collation time constraint parameters, and total error probability constraint parameters.Type: GrantFiled: September 30, 2009Date of Patent: September 11, 2012Assignee: Fujitsu LimitedInventors: Hironori Yokoi, Toshio Endoh
