Abstract: PURPOSE: A fingerprint recognition method for a personal device operated with lower power is provided to make a host system perform a floating point operation and a multiplication operation for a comparison of minutiae data between registered and input fingerprint or a fingerprint compensation, and to make a personal device, e.g., a smart card or a USB security token, repeat a fixed point operation. CONSTITUTION: The method comprises several steps. A host receives the image data of fingerprint registered by a user, generates minutiae data structure for the registered fingerprint(S30, S32, S34), and registers the minutiae data structure for the registered fingerprint at a personal device(S36). If a user transmits fingerprint image data to the host for a user authentication request, the host receives the fingerprint image data, generates the minutiae data structure, and transmits the minutiae data structure to the personal device(S38, S40, S42). The personal device extracts the same minutiae data between the registered and the newly transmitted minutiae, calculates parameters on a rotation or transition between the two image data by referring to the extracted minutiae data, encodes the calculated parameters, and transmits the encoded parameters to the host(S44). The host compensates for the minutiae data on the newly input fingerprint image by using the transmitted parameters(S46). The host matches the minutiae of the registered fingerprint with that of the compensated fingerprint, and authenticates the user or not according to the matching result(S48).

Abstract: PURPOSE: A device for recognizing a fingerprint and a method for registering/recognizing the fingerprint are provided to recognize the fingerprint only with a partial area and stable meet a quality if a fingerprint image. CONSTITUTION: A fingerprint information obtaining part(500) scans/inputs the fingerprint of a person to be inquired. A detail line image extractor(508) extracts the detail line fingerprint image by making the input fingerprint image into a detail line. A contour order assigning part(510) assigns an order by tracking each contour from the detail line fingerprint image. A contour feature calculator(512) calculates a length, a curvature, and a normal vector direction for each contour, and calculates the neighboring order contour and the inner/outer order contour of each contour. A controller(504) stores/registers various kinds of information by aligning each contour to the outer order, and distinguishes the person through the fingerprint by examining the similarity between the inputted fingerprint image and the matched fingerprint image.

Abstract: PURPOSE: A method for certifying a fingerprint by using a combination of global and local characteristic information of a fingerprint image is provided to correctly certify the fingerprint by using the first certification for the global information through an SVM(Support Vector Machine) classifier and the second certification for a local characteristic through a characteristic point matching device. CONSTITUTION: The fingerprint is obtained/registered through a fingerprint input device, and the global and the local characteristic information of the registered fingerprint are obtained(402). An SVM is generated by using the fingerprints of a user and other users. It is checked that the input fingerprint is identical with the registered fingerprint by the SVM classifier using the extracted global characteristic information used as input(406). It is checked that the input fingerprint is the registered fingerprint by comparing the extracted local characteristic information with the local characteristic information of the registered fingerprint(407). A final fingerprint certification result is drawn out by combining the first and the second checking result(408).
