Abstract: A system and method for selectively enrolling new pattern information in a way that reduces incorrect mapping or reduces overuse of previously mapped pattern information using a multi-match model. A method for dynamically enrolling a pattern-under-test into a pattern template, the pattern template including a set of template elements, may include a) determining a number N of template elements of the set of template elements matched by the pattern-under-test, wherein N is greater than one; b) establishing a multi-match mode for a dynamic enrollment of the pattern-under-test into the pattern template; and c) enrolling dynamically the pattern-under-test responsive to the multi-match mode.

Abstract: A system, method, and computer program product for efficiently mapping 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 map 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 reconstructed 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.

Abstract: 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.

Abstract: Systems and methods for detecting a user's finger or other elements may be provided. In some embodiments, the system may include a memory, a sensor area, and a processor. The sensor area may include a set of receiving electrodes which may be partitioned among a plurality of electrode groups. The system may be configured to process signals received by the electrode groups by modulating the signals received from each electrode of the respective electrode group according to a modulation pattern, and demodulating the signals, or values derived therefrom, received from each electrode of the respective electrode group according to a demodulation pattern. The electrode groups may be at least partially interleaved.

Abstract: A portable electronic system that includes a biometric imaging device, such as for a fingerprint verification against a trusted pattern template. Security is a factor of a matching process and a quality of the trusted pattern template. By employing a set of user-predictably-influenceable sensor parameters in cooperation with the biometric sensor, it is possible to simply and efficiently enhance security as compared to use of the biometric sensor alone.

Abstract: A system and method for providing a matching process that determines a conforming pattern match to a pattern-under-test from a set of matching patterns in a pattern storage. A matching process tests every template against the pattern-under-test and resolves a conforming match condition when multiple matches to the pattern-under-test are found. In some embodiments, a matcher engine using variable match thresholds may be used to differentiate among matching templates to identify a conforming-matching template with respect to the pattern-under-test.

Abstract: A system, method, and computer program product for producing a consistent desired set of operational parameters during use of a patterning solution that would otherwise alter an initial set of operational parameters. A variable match process is adjusted dynamically to counter changes to the performance metric to tend to maintain the performance metric at a desired predetermined specification.

Abstract: A system, method, and computer program product for efficiently and securely evolving a pattern, such as a fingerprint representation, from a dynamic set of impressions responsive to a pattern-under-test which may be the pattern. The system may include two modes: 1) a trusted registration mode, and 2) a dynamic, semi-trusted, registration mode. In this context, the dynamic mode is semi-trusted in that it automatically employs trusted information to evaluate new, non-trusted input received from the pattern collection system and, in an event certain criteria are satisfied, this dynamic mode may gain automatic access to the trusted memory/trusted template. That the automatic access to the trusted template is conditional makes this dynamic mode semi-trusted. The trusted registration mode may include definition/production of a trusted template of trusted template elements in a trusted memory, at least one of the trusted template elements includes at least one evolvable seed.

Abstract: A fingerprint sensor for incorporation into a smart card includes sensor electrodes for detecting fingerprint features of a finger placed on a contact surface, the sensor electrodes being disposed above a substrate layer that comprises a first portion, a second portion, and a ledge where an edge of the first portion extends beyond an edge of the second portion. Contact points disposed on the ledge connect the fingerprint sensor to electrical conductors of an intermediate layer of a multi-layer smartcard. The fingerprint sensor is disposed within a cavity formed in a body of the smartcard, and the contact points disposed on the ledge are set at a depth corresponding to the thickness of an outer layer covering the electrical conductors of the intermediate layer of the smartcard.
