Patent number: 7720262Abstract: In a method for recording reference fingerprint data for a person, at least two fingerprint images are recorded that depict at least partially different areas of one and the same finger of the person. Data from these images is stored in at least two alternative sets of reference fingerprint data that are to be used in checking the identity of the person. This method makes it possible to use a small sensor that only records partial fingerprints, both when recording reference data and when verifying, without the person having to make repeated attempts during the verification in order for the sensor to record the same area on the finger both when recording reference data and during the verification. In addition, a method is described for checking identity, in which method the fact is utilized that there are alternative sets of reference fingerprint data, and devices for carrying out the methods.Type: GrantFiled: February 18, 2003Date of Patent: May 18, 2010Assignee: Precise Biometrics ABInventor: Ola Svedin

Patent number: 7299360Abstract: A method for matching templates and a system thereof. Each template includes a plurality of data chunks, each data chunk representing a minutia and comprising a location, a minutia angle and a neighborhood. The location is represented by two coordinates. In one embodiment, each coordinate and the minutia angle are quantized. The neighborhood includes positional parameters with respect to a selected minutia for a predetermined number of neighbor minutiae. In one embodiment, a neighborhood boundary is drawn around the selected minutia and neighbor minutiae are selected from the enclosed area. A reference template is compared to a measured template on a chunk-by-chunk basis. A chunk from each of the template is loaded into a random access memory (RAM). The location, minutia angle and neighborhood of the reference data chunk are compared with the location, minutia angle and neighborhood of the measured data chunk, respectively.Type: GrantFiled: December 16, 2003Date of Patent: November 20, 2007Assignee: Precise BiometricsInventor: Anthony P.

Patent number: 7035441Abstract: In a method of preventing false acceptance in a system for checking fingerprints, a latent fingerprint on the sensor (1) is detected by the location of a currently recorded fingerprint being compared with the location of a previously recorded fingerprint. If the location essentially corresponds, the recorded fingerprint is considered as originating from a latent fingerprint, and the fingerprint is rejected. Otherwise, the fingerprint is considered as originating from an actual finger on the sensor.Type: GrantFiled: April 27, 2001Date of Patent: April 25, 2006Assignee: Precise Biometrics ABInventors: Jerker Bergenek, Björn Nordin
