摘要:
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.
摘要:
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.

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.
摘要:
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.
