Methods and systems are provided for providing directional assistance to guide a user to position a camera for centering a person's face within the camera's field of view. A neural network system is trained to determine the position of the user's face relative to the center of the field of view as captured by an input image. The neural network system is trained using training input images that are generated by cropping different regions of initial training images. Each initial image is used to create a plurality of different training input images, and directional assistance labels used to train the network may be assigned to each training input image based on how the image is cropped. Once trained, the neural network system determines a position of the user's face, and automatically provides a non-visual prompt indicating how to center the face within the field of view.

Some disclosed methods may involve receiving an indication of a digit touching a surface of an apparatus in an active fingerprint sensor area, obtaining current fingerprint image data from the digit and performing a first authentication process based, at least in part, on the current fingerprint image data. Responsive to determining that the first authentication process is an unsuccessful authentication process, some methods may involve obtaining non-digit image data after the digit has been removed from the surface, performing a second authentication process based, at least in part, on the non-digit image data and providing a notification regarding the outcome of the second authentication process. In some examples, the non-digit image data may be obtained and the second authentication process may be performed without providing a notification regarding the unsuccessful outcome of the first authentication process.

Exemplary embodiments relate to a method for unlocking a mobile device using authentication based on ear recognition including obtaining an image of a target showing at least part of the target's body in a lock state, extracting a set of ear features of the target from the image of the target, when the image of the target includes at least part of the target's ear, and determining if the extracted set of ear features of the target satisfies a preset condition, and a mobile device performing the same.

To provide a technology of more accurately detecting spoofing in face authentication, without increasing a scale of a device configuration and a burden on a user. A spoofing detection device includes a facial image sequence acquisition unit, a line-of-sight change detection unit, a presentation information display unit, and a spoofing determination unit. The facial image sequence acquisition unit acquires a facial image sequence indicating the face of a user. The line-of-sight change detection unit detects information about a temporal change in the line-of-sight from the facial image sequence. The presentation information display unit displays presentation information presented to the user as part of an authentication process. The spoofing determination unit determines the likelihood of the face indicated by the facial image sequence being spoofing on the basis of the information about the temporal change in the line-of-sight with respect to the presentation information.

An imaging device includes: an imaging portion that captures an image of a portion of a living body to take in the image; a display portion that displays first and second display images with being superimposed on each other, the first display image being based on the taken-in image, the second display image including guidance regarding a way to place the portion of the living body in a prescribed position; a determination portion that determines whether the portion of the living body is placed in the prescribed position; and a control portion that, until it is determined that the portion of the living body is placed in the prescribed position, causes the imaging portion to newly capture and take in a new image of the portion of the living body and causes the display portion to display an image based on the new taken-in image.

According to various, but not necessarily all, embodiments there is provided an apparatus comprising means for: determining at least two locations at which a user touches a device; selecting a first location and a second location from the at least two locations to define a transmission path for an acoustic signal through the user; applying an acoustic signal to the user through the first location; detecting an acoustic signal transmitted through the user at the second location; and analysing the detected acoustic signal to determine if it is indicative of transmission of the applied acoustic signal through an authorised user based on a known bioacoustic signature of the authorised user.

This invention is directed to an electronic device with an embedded authentication system for restricting access to device resources. The authentication system may include one or more sensors operative to detect biometric information of a user. The sensors may be positioned in the device such that the sensors may detect appropriate biometric information as the user operates the device, without requiring the user to perform a step for providing the biometric information (e.g., embedding a fingerprint sensor in an input mechanism instead of providing a fingerprint sensor in a separate part of the device housing). In some embodiments, the authentication system may be operative to detect a visual or temporal pattern of inputs to authenticate a user. In response to authenticating, a user may access restricted files, applications (e.g., applications purchased by the user), or settings (e.g., application settings such as contacts or saved game profile).

A control circuit configured to control a display panel includes a display driver circuit, a touch sensing circuit and a fingerprint sensing circuit. The touch sensing circuit, coupled to the display driver circuit and the fingerprint sensing circuit, is configured to detect a finger touch on the display panel, determine a position of the display panel on which the finger touch is detected, and send information associated with the position to the fingerprint sensing circuit. The fingerprint sensing circuit is configured to perform fingerprint sensing on at least one zone corresponding to the position and receive fingerprint image signals from the at least one zone correspondingly.

In some examples, a computing device may display a user interface (UI) to configure a multiple print unlock. The UI may determine a first plurality of prints placed on a touchscreen. Individual prints of the first plurality of prints may include a thumb print or a fingerprint. After the computing device has been inactive for a predetermined amount of time, the UI may lock the computing device. The UI may determine a second plurality of prints placed on a touchscreen and perform a comparison of the second plurality of prints to the first plurality of prints. If the UI determines that the second plurality of prints matches the first plurality of prints, then the UI may unlock the computing device. If the UI determines that the second plurality of prints does not match the first plurality of prints, then the computing device may remain locked.

Systems and methods for enrolling and authenticating a user in an authentication system via a user's camera of camera equipped mobile device include capturing and storing enrollment biometric information from at least one first image of the user taken via the camera of the mobile device, capturing authentication biometric information from at least one second image of the user, capturing, during imaging of the at least one second image, path parameters via at least one movement detecting sensor indicating an authentication movement of the mobile device, comparing the authentication biometric information to the stored enrollment biometric information, and comparing the authentication movement of the mobile device to an expected movement of the mobile device to determine whether the authentication movement sufficiently corresponds to the expected movement.
