Assignee:

Veridicom, Inc. - Sunnyvale CA

International Classification:

G06K 900

US Classification:

382124, 340 583

Abstract:

A method of operating a personal verification system includes acquiring with a sensor a first image of a first biometric feature, removing background noise associated with the sensor from the image, and storing at least a portion of the first image. The method also includes acquiring with the sensor a second image of a second biometric feature and comparing at least a portion of the second image with the first image. If the second image is substantially different from the first image, the second image is displayed.

Veridicom, Inc. - Sunnyvale CA

International Classification:

G06K 900

US Classification:

382125, 382209

Abstract:

A method for combining two templates. A first template having a first minutia set and a second template having a second minutia set are provided. The first template is compared with the second template to obtain a matching minutia set. Registration parameters are calculated from the matching minutia set. The registration parameters can be referenced to either the first minutia set or the second minutia set. All minutiae in the first or the second minutia set are translated to be on the same coordinate system as the other minutia set. The minutia sets are then combined to construct a combined minutia set. In one embodiment, an overlap region is drawn for the first template and the second template, the overlap region containing at least minutiae from the matching minutia set. The combined minutia set is constructed from the matching minutiae in the first or the second template, minutiae in the first minutia set that are not in the matching minutia set, and minutiae in the second minutia set that are not in the matching minutia set. In another embodiment, minutiae in the overlap region but not part of the matching minutia set are discarded.

International Classification:

G06K 900

US Classification:

382125, 902 6

Abstract:

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. In one embodiment, the comparison uses straight subtractions.

International Classification:

G06K 9/00

US Classification:

382125

Abstract:

Method and system for reconstructing seamless fingerprint image from set of image slices, or frames, from fingerprint swipe sensor. Robust normalized cross-correlation procedures are used for frame evaluation and image matching. Efficient use of device processing resources including memory by keeping only data frames that indicate moving finger and discards frames where no finger exists at sensor during acquisition or finger has not moved since last frame was acquired. Capability to adjust sensor settings during acquisition process to obtain optimal results. Logic ensures operation across different physical systems and sensor characteristics with varying acquisition speeds. Statistics regarding resulting reconstructed image and finger swiping process are computed and embedded in reconstructed image and are useful to the downstream fingerprint matching system, and by embedding in image, inventive system and method ensure that any fingerprint processing system can use information if when called upon to do so.

US Classification:

382124, 382115, 340 553, 340 583

Abstract:

The present invention discloses a system for and method of calculating pressure differences using a finger sensor. A finger sensor system in accordance with the present invention comprises a finger sensor for capturing first and second of sets of image data by contacting the finger sensor and means for providing a statistical comparison between the first and second sets of image data to determine a total pressure difference. The means for providing a statistical comparison comprises a means for generating first histogram data from the first set of image data and second histogram data from the second set of image data. The means for providing statistical data correlates peaks of the first and second histogram data and also determines differences between variances of the first and second sets of image data.

US Classification:

382124, 345157, 715856

Abstract:

A system and method of the present invention emulates electronic input devices such as a steering wheel, a mouse, a joystick, a navigation bar, a scroll wheel, and a pressure-sensitive button. The method comprises swiping a finger on a swipe sensor, calculating a difference between a first position of the finger on the swipe sensor and a second position on the swipe sensor, and translating the difference into a plurality of sets of signals. Each set of signals is used to emulate the signals generated by one of the electronic input devices. The method thus uses a single swipe sensor to emulate multiple electronic input devices. In a preferred embodiment, the system is used to control a display on a portable electronic device is coupled to or forms part of the portable electronic device.

US Classification:

382124, 382125, 340 553, 340 583

Abstract:

A biometric secured system grants a user access to a host system by classifying a fingerprint used to verify or authorize the user to the system as real or fake. The classification is based on a probability that fingerprint image data corresponds to characteristics that reliably identify the finger as real. The system includes a fingerprint sensor for capturing fingerprint image data coupled to a spoof detection module. In one embodiment, the spoof detection module is programmed to determine spoof probability based on a combination of metrics that include, among other metrics, pixel gray level average and the variance of pixels corresponding to a fingerprint ridge, pixel gray level average and the variance of pixels corresponding to a fingerprint valley, density of sweat pores, and density of sweat streaks, to name a few metrics.
