A node server for autonomously authenticating a user is disclosed that comprises a node database for storing authentication data associated with the user and an authentication SDK configured to perform authentication using data from the node database. The node server also includes a node API for creating and maintaining the node server and for routing payment to a cloud service that is hosting the node server. A communication interface is configured to process communication with a user device, such that the user device is executing software associated with a user account. An access module is configured to permanently and irrevocably prevent access from external servers or devices not associated with a user account, after creation and activation of the node server.

In accordance with various embodiments, a self-service checkout terminal can comprise: a capture device having at least one sensor, wherein the capture device is configured: to capture first biometric data with reference to a person at the self-service checkout terminal; to capture second biometric data with reference to an official identity certificate if the identity certificate is presented to the capture device; to capture a product identifier of a product if the product is presented to the capture device; a control device configured for: firstly determining a sales restriction to which the product is subject, on the basis of the product identifier; comparing the first biometric data with the second biometric data; secondly determining whether the person satisfies a criterion of the sales restriction on the basis of a result of the comparing and on the basis of the second biometric data.

There is provided an information processing apparatus including a processing unit that performs living body-related processing on the basis of an image of a part of a living body of a user, the image being generated in a state in which the part of the living body is in contact with a contact surface, and contact information acquired in the state in which the past of the living body is in contact with. the contact surface.

An authentication device includes: a wearing position determination unit that determines a wearing position, the wearing position being a position at which a wearable article comprising a sensor is being worn on a body; and an authentication unit that performs authentication by using biometric information of the body, the biometric information being detected by the sensor at the wearing position.

A user-guidance system that utilizes augmented-reality (AR) components and human-posture-detection techniques is presented. The user-guidance system can help users to use smart devices to conduct 3D body scans more efficiently and accurately. AR components are computer generated for the on-screen guidance to guide a camera operator to position the camera in a particular location in relation to a target object with a particular tilt orientation in relation to the target object to capture an image that includes a region of the target object for 3D reconstruction of the target object. Human-posture-detection techniques are used to detect a human user's real-time posture and provide real-time on-screen guidance feedback and instructions to the human user to adopt an intended best posture for 3D reconstruction of the human user.

A wearable device for use in immersive reality applications is provided. The wearable device includes eyepieces to provide a forward-image to a user, a first forward-looking camera mounted on the frame and having a field of view, a processor configured to identify a region of interest within the forward-image, and an interface device to indicate to the user that a field of view of the first forward-looking camera is misaligned with the region of interest. Methods of use of the device, a memory storing instructions and a processor to execute the instructions to cause the device to perform the methods of use, are also provided.

A method may involve controlling, via a control system, the apparatus to provide a first prompt to place a digit on an outer surface of the apparatus in a fingerprint sensor system area. The method may involve determining, via the control system, a digit force or a digit pressure of the digit on the outer surface of the apparatus. The method may involve controlling, via the control system, the apparatus to provide a second prompt corresponding to the digit force or the digit pressure.

A fingerprint prompt pattern display method includes obtaining a first trigger instruction, where the first trigger instruction is used to instruct to display a fingerprint prompt pattern; and displaying N preset fingerprint prompt patterns in a fingerprint prompt area in turn, where display positions of displaying the N fingerprint prompt patterns in the fingerprint prompt area do not completely overlap, and N is an integer greater than or equal to 2.

A device for authenticating a user is described that comprises a sensor configured to measure the movement of a user in response to the interaction of the user with a displayed image and controller circuitry configured to authenticate the user in response to a positive comparison between the movement of the user and a stored movement associated with the user.

A biometric biochemical analysis system includes a user interface module to provide instructions for collecting and handling biochemical sampling and processing related to biometric data gathering as well as capturing biometric data using digital data capturing devices. The user interface module and display are integrated with analysis and communications portions of the biometric biochemical analysis system to provide a portable system for multi-portion data collecting, storage, verification, and analysis.
