Patent number: 10621765Abstract: A system, method, and computer program product for efficiently reconstructing a pattern, such as a fingerprint, from a set of multiple impressions of portions of that pattern. The system may evaluate images of patterns taken from a series of multiple impressions and reconstruct the pattern from the image portions while providing the operator with realtime feedback of a status of the set of images. As each new image portion is evaluated, a display graphic or other indicator provides feedback when a new image portion is added to the reconstruction image, or when a new image portion is not added (such as it representing a duplicate). Other status indications may be provided, and when the indication is visual, a degraded resolution of the pattern map may be provided on the display graphic to improve security.Type: GrantFiled: July 5, 2016Date of Patent: April 14, 2020Assignee: IDEX ASAInventors: Roger A. Bauchspies, Sigmund Clausen, Arne Herman Falch

Patent number: 9928401Abstract: A system and method for biometric enrollment and verification compares a test biometric image (e.g., of a fingerprint) with each of a plurality of reference biometric images of one or more enrolled users. Verification of a user as an enrolled user is based on the cumulative amount of overlap between the test image and the reference images. The reference images are defined during an enrollment process by comparing a plurality of sample images, identifying overlapping data in each of the images, computing one or more quality measures, and storing at least a portion of the sample images. The enrollment process is deemed complete when each quality measures meets or exceeds an associated threshold.Type: GrantFiled: April 14, 2017Date of Patent: March 27, 2018Assignee: IDEX ASAInventor: Sigmund Clausen

Patent number: 8195285Abstract: A method and sensor assembly for determining the condition of a structure, especially for confirming if a measured fingerprint is on a live finger, measures characteristics of close to the structure surface. The sensor includes a first pair of current supply electrodes coupled to a current source, providing an electrical current to the skin, at least two pickup electrodes at chosen and different positions relative to the current supply electrodes, at least a first of the pickup electrodes being coupled to an instrument for measuring the voltage between the first pickup electrode and at least one of the pickup or current supply electrodes, storage for a predetermined set of values characterizing a certain condition of the surface, and means for comparing the characteristics from each pickup electrode with the measurements of the other pickup electrodes and with the predetermined set of characteristics for determining the surface condition.Type: GrantFiled: December 6, 2010Date of Patent: June 5, 2012Assignee: Idex ASAInventors: Orjan G. Martinsen, Jon Nysaether, Knut Riisnaes, Ingvild Juvkam Dyve, legal representative, Geir Mostad, Rune Pedersen, Nicolai W. Christie, Sigmund Clausen
