摘要： Provided is a fingerprint matching method and apparatus using fingerprint minutiae and fingerprint binary images. The method includes: constructing a template fingerprint database by extracting minutiae information and a binary image of a first fingerprint image; and extracting minutiae information and a binary image of a second fingerprint image to be authenticated and performing authentication by aligning the extracted minutiae information and the binary image of the second fingerprint image with data in the template fingerprint database. Accordingly, the fingerprint matching using the fingerprint binary images is additionally performed, thereby reducing a false acceptance rate (FAR) compared to a conventional minutia-based fingerprint authentication method.

摘要： A method and apparatus for classifying fingerprint image quality and a fingerprint image recognition system are provided. The method includes dividing a fingerprint image into a plurality of blocks, calculating and vectorizing quality classification parameters with respect to the respective blocks, obtaining quality classification values for the respective blocks by inputting the vectorized quality classification parameters into a trained quality classifier, and selecting a representative value of the quality classification values and determining the representative value as the quality of the fingerprint image. Since the quality of the fingerprint image can be accurately judged, reliability of the fingerprint image recognition system is increased.

摘要： Provided are an integrated authentication method and system using biometrics. In an integrated authentication system including a client, a plurality of service providing servers where user identification information of the client is registered, and an integrated server where user biometric information together with the user identification information is registered, to integratedly authenticate access of the client to the service providing servers, the client acquires authentication of access to a first service providing server by using the user biometric information and the user identification information through the integrated sever. When the access is permitted, the client receives a first access permission message generated by the first service providing server and stores the first access permission message. The client acquires authentication of access to a second service providing server by using the first access permission message and the user identification information.

摘要： Provided are a method and apparatus for identifying a fingerprint. The method uses minutiae points of the fingerprint and includes (a) enrolling a fingerprint of a first user in a first database by extracting n minutiae points from a fingerprint image of the first user; selecting one of the n minutiae points as a reference point; rotating the other minutiae points by a predetermined angle with respect to the reference point; generating a first user table containing information regarding the first user's fingerprint based on geometrical changes of the other minutiae points which are obtained by the rotation; and storing the first user table in the first database; and (b) identifying a fingerprint of a second user by extracting m minutiae points from a fingerprint image of the second user; selecting one of the m minutiae points as a reference point; generating a second user table containing information regarding the second user's fingerprint based on geometric changes of the other minutiae points obtained by rotating the other minutiae points by an angle about the reference point; comparing the second user table with the first user table, and selecting a similar candidate list of user tables (m and n are integers). Accordingly, it is possible to enroll a large amount of information regarding fingerprints in a database using quantization and geometric hashing while using a limited storage memory of a central database. Further, it is possible to accurately identify and detect a user's fingerprint in real time using geometric hashing and parallel processing.

The method for performing multi-model biometric identification by using a plurality of single biometric identification systems includes: receiving from the single biometric identification system a single biometric comparison value generated by comparing biometric information of a user for whom an identity confirmation request is received, with biometric information of previously registered users; with the single biometric comparison value, generating a comparison value vector for each registered user; in relation to each of registered users, verifying whether or not the comparison value vector is generated by comparison of an identical person and generating a determined value; and by using the determined value, generating a candidate list listing in a predetermined order, users who have highest probabilities of being the user who wants to be identified. Accordingly, by using a variety of biometric characteristics, more accurate identification of a user is enabled.
