An apparatus for generating biometric information, the apparatus includes a biometric scanning module configured to scan a body of a user to generate biometric image information; a seed supplying module configured to supply a secure seed having a security that is effective for a preset time period; a security pattern generating module configured to generate a secure watermark pattern based on the secure seed; and a biometric information generating module configured to generate biometric information to be used for authentication by the use of the biometric image information and the secure watermark pattern.

Generation and authentication of biometric information using watermark

A method for an optical fingerprint recognition, the method includes scanning a fingerprint image using a multiple scan which allows alternating a first scan condition and a second scan condition different from each other; determining whether an input fingerprint is a dry fingerprint depending on a darkness level of a fingerprint image derived from the first scan condition; and performing a fingerprint recognition using a fingerprint image derived from the first scan condition or a fingerprint image derived from the second scan condition in accordance with the determination result as to the dry fingerprint.

Method and apparatus for optical fingerprint recognition using multiple scan

An apparatus for processing a fingerprint image, the apparatus includes a noise information estimation unit configured to estimate information for a noise removal from at least two or more images recognized for a first section before a point of time when a fingerprint contact is initiated. The apparatus includes a fingerprint image acquiring unit configured to correct at least one image recognized for a predetermined time period after the completion of the fingerprint contact using the estimated information to acquire the fingerprint image.

Apparatus and method for reducing noise in fingerprint images

In accordance with the embodiments of the present invention, the biometric information created for biometric authentication is available for a predetermined time after it was acquired. In addition, the authentication processing is performed on the biometric information useful for a predetermined time after the biometric information was acquired when authenticating it. Therefore, the authentication processing can be normally performed on only the biometric information that is acquired immediately when it is necessary for the user to do the financial transaction or individual authentication.

Creation and authentication of biometric information

A method for an optical fingerprint recognition, the method includes scanning a fingerprint image separately using a multiple exposure which allows alternating a short exposure and a normal exposure; determining whether there is an inflow of external light depending on a darkness level of a fingerprint image derived from the normal exposure; and performing a fingerprint recognition using a fingerprint image derived from the short exposure or the fingerprint image derived from the normal exposure in accordance with the determination result as to the inflow of external light.
