摘要： The present invention relates to a fingerprint sensing device comprising an array of sensing elements; readout circuitry connected to the array of sensing elements; and finger detecting circuitry for detecting if a finger candidate is touching the sensing surface of the fingerprint sensing device. The fingerprint sensing device is controllable between an active state and an inactive state. When the fingerprint sensing device is in the inactive state, the finger detecting circuitry is configured to provide a finger lost signal for indicating when the finger candidate no longer touches the sensing surface of the fingerprint sensing device.

摘要： A non-parametric computer implemented system and method for creating a two dimensional interpretation of a three dimensional biometric representation. The method comprises: obtaining with a camera a three dimensional (3D) representation of a biological feature; determining a region of interest in the 3D representation; selecting an invariant property for the 3D region of interest; identifying a plurality of minutiae in the 3D representation; mapping a nodal mesh to the plurality of minutiae; projecting the nodal mesh of the 3D representation onto a 2D plane; and mapping the plurality of minutiae onto the 2D representation of the nodal mesh. The 2D representation of the plurality of minutiae has a property corresponding to the invariant property in the 3D representation; and the value of the corresponding property in the 2D projection matches the invariant property in the 3D representation.

摘要： A system, method, and computer program product for evaluating a conformance of sets of curves using curvature information from curve segments to identify conforming curve segments. These curve segments are evaluated for relative positional variations in a context of a cluster by triangulating corresponding points among the curve segments of the cluster. Little to no deviation between corresponding lengths in the clusters indicate a high probability of match. Confirmation may be done by a more rigorous pattern matcher based upon the conforming curve segments of a cluster.

摘要： The disclosed technology provides optical anti-proofing techniques in fingerprints sensing in devices or systems that use fingerprint identification for controlling access. The disclosed technology uses a fingerprint sensor to detect a contact input associated with a source of a fingerprint; generates an image signal from the fingerprint sensor responsive to the detected contact input that is indicative of one or more images of the fingerprint; uses an optical biometric sensor that is separate from the fingerprint sensor to generate a biometric marker detection signal indicative of a biometric marker different from the fingerprint; and processes, by processing circuitry, the generated image signal and the biometric marker detection signal to determine whether the detected contact and the associated one or more fingerprint images are from a finger of a live person who makes the contact input.

摘要： A method and apparatus for processing the images of fingerprints, whereby aligned images are subjected to a tessellation process, wherein each image is partitioned into a number of regions. Within each region at least one parameter associated with the ridges is measured and stored: the prevailing ridge orientation, the average ridge separation and the phase of the ridges. The data is projected and stored in a multidimensional coordinate system wherein the representations of any two data are separated by an amount corresponding to the dissimilarity of these data.
