摘要： 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. If a result of the determining satisfies the authentication information compensation condition, the first biometric authentication information is compensated by using the first biometric input information or the second biometric authentication information is compensated by using the second biometric input information.

摘要： A fingerprint image acquisition method for user authentication is provided. The method comprises determining whether a sensed pressure, which is applied to a fingerprint input window by a finger of a user touching the fingerprint input window, exceeds a predetermined startup pressure, acquiring a comparison image by imaging a fingerprint of the finger when the sensed pressure exceeds the startup pressure, measuring a quality of the comparison image, determining a value of a threshold pressure based on the quality of the comparison image and acquiring an authentication image for the user by capturing an image of the fingerprint of the finger when the sensed pressure exceeds the threshold pressure.

摘要： 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. A part of the blurred pseudo image at the determined corresponding position is converted to a clear partial pseudo-image having a higher resolution than that of the blurred pseudo image and the clear partial pseudo-image is displayed. The acquired fingerprint image is registered as an authentication-purpose fingerprint image in association with the converting and outputting process.

摘要： 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. If NO in the fifth step, processes of the first to fifth steps are repeated. If YES in the fifth step, a success of the authentication is determined and outputted.

摘要： A method for acquiring a fingerprint image through a fingerprint image acquisition apparatus is provided. The method includes recognizing a finger of an user through a sensor included in the apparatus to generate an initial input fingerprint image when the finger contacts with a biometric recognition area of the display unit, acquiring a converted fingerprint image by converting the initial input fingerprint image in a pre-determined manner to reveal a characteristic of a pattern, included within the initial input fingerprint image, corresponding to a pattern signal reflected from at least a part of the display unit. The method further includes selecting a pattern removal fingerprint image, if a learned pattern image is stored in a memory, from the learned pattern image based on similarity. The similarity is calculated between the converted fingerprint image and a converted reference image.
