The present invention provides a matching result display device, a matching result display method, a program, and a recording medium, which allow, at the time of displaying feature points of objects determined as matching on the basis of matching result information provided by a matching system, visual check of the displayed feature points to be performed easily. The matching result display device according to the present invention includes: a feature point acquiring unit that acquires a plurality of feature points common to at least two pieces of image data to be matched against each other; a display position setting unit that sets display positions of corresponding symbols to be assigned to the feature points common to the at least two pieces of image data in such a manner that, when the same corresponding symbols are assigned to corresponding feature points, respectively, a display line connecting each feature point and the corresponding symbol assigned thereto on each of the at least two piece of image data does not overlap with display lines connecting other feature points and corresponding symbols assigned thereto, respectively; and a display unit that provides the corresponding symbols at the display positions and displays the feature points and the corresponding symbols assigned thereto in a state where they are connected with display lines, respectively.

A striped pattern image examination support apparatus includes a feature extraction part, a central line collation part, and a display part. The feature extraction part extracts, from each of a first striped pattern image and a second striped pattern image, at least central lines and feature points, as a feature of each of the first striped pattern image and the second striped pattern image. The central line collation part performs collation of the respective central lines of the first striped pattern image and the second striped pattern image, and computes corresponding central lines between the first striped pattern image and the second striped pattern image. The display part determines a display form of each of the central lines based on the computed corresponding central lines and superimposes and displays the central lines on each of the first striped pattern image and the second striped pattern image, according to the determined display form.

An authentication information processing method for an authentication information processing device including a processor and a memory includes acquiring an image, determining a base point representing a sweat pore on a ridge of skin from the acquired image, and acquiring position information. The authentication information processing method includes extracting a predetermined number of the base points whose distance from the central base point is less than a predetermined value and for which a number of troughs between adjacent two of the ridges of the skin positioned between the central base point and each of the predetermined number of base points is equal to or less than one, as peripheral base point. The authentication information processing method includes generating sweat pore-related information associating the position information of the central base point with attribute information, and causing the memory to store the generated sweat pore-related information.

A method for fingerprint recognition and related products are provided. The method is applicable to an electronic device including a fingerprint recognition module and a display screen which has a fingerprint recognition region. The method includes the following. When a user presses the display screen, a target pressed region corresponding to the fingerprint recognition module is determined. When the area of the target pressed region is less than a preset area threshold, the fingerprint recognition module is controlled to operate in a first fingerprint collection mode to obtain a first fingerprint image, where in the first fingerprint collection mode, fingerprint collection is performed based on a first region of a first size. When the area of the target pressed region is greater than the preset area threshold, the fingerprint recognition module is controlled to operate in a second fingerprint collection mode to obtain a second fingerprint image.

A system and methods for authenticating an electronic signature using a biometric fingerprint includes registering a subscriber to the service. The subscriber asks document signers enter their fingerprint(s) by a fingerprint reader. The fingerprint data is applied to a fingerprint matcher which generates a gallery pair table of fingerprint minutiae for each signer. A secret user ID or operation number is generated. A sharing module splits the fingerprint information into N shares and generates a threshold number S. The secret is applied to the sharing module and N shares of the secret are generated. The N shares of fingerprint data are each combined with one share the secret to form N combined shares. The N combined shares are each stored in different cloud storage locations. Retrieval of the secret to authenticate the signers requires S signers to enter their fingerprints and S combined shares to be downloaded from the clouds.

An apparatus may include a cover layer, a layer of first metamaterial proximate (or in) the cover layer, a light source system configured for providing light to the layer of first metamaterial and a receiver system. The first metamaterial may include nanoparticles configured to create ultrasonic waves when illuminated by light. The receiver system may include an ultrasonic receiver system configured to receive ultrasonic waves reflected from a target object in contact with, or proximate, a surface of the cover layer. The control system may be configured to receive ultrasonic receiver signals from the ultrasonic receiver system corresponding to the ultrasonic waves reflected from the target object and to perform an authentication process and/or an imaging process that is based, at least in part, on the ultrasonic receiver signals.

An apparatus may include a processor that may be caused to access handholding information indicating a hand configuration in which the apparatus is being held and compare the handholding information with previously-stored handholding authentication data of an authentic user. The previously-stored handholding authentication data may represent an authentic configuration in which the apparatus is held by the authentic user. The processor may be caused to determine that the apparatus is being held by the authentic user based on the comparison and cause an authenticated action to occur based on the determination.

A fingerprint authentication method and device, display device, and biometric security apparatus include: a fingerprint sensor; a minutiae extraction circuit connected to the fingerprint sensor; a minutiae storage circuit connected to the minutiae extraction circuit; and a minutiae match circuit connected to the minutiae extraction circuit and the minutiae storage circuit, wherein the minutiae match circuit includes a class-wise comparator having a first input connected to the minutiae extraction circuit for receiving sensed fingerprint minutiae from each class of a plurality of classes, a second input connected to the minutiae storage circuit for receiving stored fingerprint minutiae belonging to each same class of the plurality of classes, respectively, and an output providing a fingerprint authentication signal responsive to the class-wise comparator.

There is provided an information processing apparatus and an information processing method capable of improving security against leakage of a registered fingerprint in fingerprint authentication. Collation is performed on the basis of whether or not a feature amount of a partial region of an entire fingerprint imaged by a fingerprint imaging unit and a method of operation on the fingerprint imaging unit match the feature amount of the partial region of the entire fingerprint and the method of operation registered in advance. Application to a fingerprint authentication device is possible.

A contactless authentication system includes: at least one illumination apparatus that projects illumination light onto a portion of a hand, the portion being not in contact of an object, the illumination light containing a light component in a wavelength range greater than or equal to 1380 nm; and an imaging apparatus that obtains at least one selected from the group consisting of a fingerprint image and a palm print image as authentication information by imaging the light component in the wavelength range in reflected light generated by reflection of the illumination light from the portion of the hand.
