Apparatus for identifying fake fingerprint and manufacturing method thereof

An apparatus for identifying a fake fingerprint includes a housing, a prism, a first light source unit, a second light source unit, a sensor unit and a control unit. The prism is disposed in the internal space of the housing. ... Suprema Inc

Method and system for managing door access using beacon signal

A method and system allow management of access to a door using a beacon signal. A user access authority determination unit controls access of a user to a target door based beacon data from beacons installed near a door. ... Suprema Inc

Method and device for fingerprint authentication

A fingerprint authentication method includes a first step of acquiring partial fingerprint measurement data for a part of a fingerprint, and a second step of calculating a matching rate by comparing the partial fingerprint measurement data with reference comparison data selected among a plurality of partial fingerprint registration data, each partial fingerprint registration data corresponding to a part of a fingerprint. The method further includes a third step of determining whether the matching rate is equal to or greater than an authentication threshold and a fourth step of determining, based on a result in the third step, a success of the authentication, or repeating the second and third steps by selecting new reference comparison data based on whether or not the matching rate is equal to or greater than a preset threshold smaller than the authentication threshold.. ... Suprema Inc

Method and device for fingerprint authentication

There is provided a fingerprint authentication method. The method includes a first step of acquiring measurement data for a part of a fingerprint, a second step of calculating a matching rate by comparing the measurement data with at least one of a plurality of registration data, a third step of determining whether the matching rate is equal to or greater than a threshold and whether the measurement data has been previously processed for an authentication, a fourth step of calculating a security level accumulation value based on a result of the third step, and a fifth step of determining whether the security level accumulation value is equal to or greater than a threshold. ... Suprema Inc

Control methods of decryption key storage server, biometric information storage server, and matching server in authentication system

Provided are control methods of a decryption key storage server, a biometric information storage server, and a matching server in an authentication system. The control method of a decryption key storage server in an authentication system includes: acquiring an identifier of a target client and a encrypted biometric information for authentication; acquiring biometric information for registration corresponding to the identifier to be matched among pieces of the biometric information for registration having been encrypted by the at least one client transmitting the biometric information for registration; extracting a decryption key corresponding to the identifier from the at least one decryption key; decrypting the encrypted biometric information for authentication and the biometric information for registration corresponding to the identifier using the decryption key corresponding to the identifier; and determining whether or not the decrypted biometric information for authentication and the decrypted biometric information for registration corresponding to the identifier match.. ... Suprema Inc

Fingerprint data registering method and fingerprint data registering apparatus

In a fingerprint data registering method, a blurred pseudo image is displayed and, when a fingerprint image for authentication registration is acquired, a fingerprint position of the acquired fingerprint image is extracted. A position in the pseudo image, which corresponds to the extracted fingerprint position, is determined. ... Suprema Inc

Method for authenticating fingerprint and authentication apparatus using same

There is provided a method for authenticating a fingerprint. The method includes receiving an inputted fingerprint image; selecting a plurality of comparison target pixels from pixels in the inputted fingerprint image and selecting a plurality of comparison reference pixels from pixels in a pre-stored registered fingerprint image; and determining a similarity of an overlapping area where the inputted fingerprint image overlaps the registered fingerprint image whenever a matching arrangement of each of the comparison target pixels is made with respect to each of the comparison reference pixels. ... Suprema Inc

Biometric authentication using gesture

There is provided a biometric authentication method using a portable electronic device. The method includes identifying a gesture of a user to be authenticated through a gesture recognition unit of the portable electronic device and acquiring biometric information of the user through an information input unit of the portable electronic device. ... Suprema Inc

Biometric information management method and biometric information management apparatus

In a biometric information management method, a first comparison result is acquired by comparing first biometric input information with registered first biometric authentication information and a second comparison result is acquired by comparing second biometric input information with registered second biometric authentication information. Further, satisfaction or non-satisfaction of a predetermined authentication information compensation condition is determined based on the first comparison result and the second comparison result. ...
