Abstract: Methods, systems, and apparatuses are described herein for improving the security of computer authentication using light communications data provided by, e.g., environmental Li-Fi light sources. A mobile device may receive light communications data from a light source, such as a Li-Fi-enabled light bulb in a physical environment of the mobile device. That light communications data may indicate a variation in a modulation of light intensity of the light source over a time period. That variation might be used to provide a time- and/or location-specific key. The mobile device may determine the key by processing the light communications data and transmit a request for content that comprises the key. Access to content may be provided to the mobile device based on the key.

Abstract: A device may capture a plurality of preview frames of a document, and for each preview frame of the plurality of preview frames, process the preview frame to identify an object in the preview frame. Processing the preview frame may include converting the preview frame into a grayscale image, generating a blurred image based on the grayscale image, detecting a plurality of edges in the blurred image, defining at least one bounding rectangle based on the plurality of edges, and determining an outline of the object based on the at least one bounding rectangle. The device may determine whether a value of an image parameter, associated with the one or more preview frames, satisfies a threshold, and provide feedback to a user of the device, or automatically capture an image of the document, based on determining whether the value of the image parameter satisfies the threshold.

Abstract: Embodiments disclosed are directed to a computing system that performs steps to perform enhanced device fingerprinting using user contacts data. The computing system receives, from an application, a first plurality of device attributes identifying a client device on which the application is being used. The first plurality of device attributes includes first device identification data and first user contacts data. Subsequently, when a user is attempting to perform a transaction using the application on the client device, the computing system receives, from the application, a second plurality of device attributes identifying the client device on which the application is being used. The second plurality of device attributes includes second device identification data and second user contacts data. The computing system compares the second plurality of device attributes to the first plurality of device attributes to determine whether the user is authorized to perform the transaction.

Abstract: A user device may capture an image including an object, and may identify the object, including determining an outline of the object. The user device may determine a first center point of the object and an angle of orientation of the object in relation to the image. The user device may rotate the image based on the angle of orientation, including changing one or more dimensions of the image. The user device may, after rotating the image, determine the one or more dimensions of the rotated image, calculate one or more offset values associated with changing the one or more dimensions of the rotated image, and determine a second center point of the object based on the first center point and the one or more offset values. The user device may perform an action related to the rotated image based on determining the second center point of the object.

Abstract: Described herein is a system for automatically capturing images. A device may execute an application on the device. In response to receiving a request for capturing an image of a document, the application may control the operation of the camera to contemporaneously and continuously capture image frames of an area within the field of view of a camera of the device. The field of view may include an object and in turn may be included in the captured image frames. The application may determine whether the aspect ratio and real-world size of the object in the captured image frames corresponds with a specified threshold size and aspect ratio which corresponds with a given document type. In response to determining the object corresponds to the given document type, the camera may automatically extract an image of the object.

Abstract: Disclosed herein are various embodiments for detecting predefined accessibility patterns for modifying a user interface of a mobile device. An embodiment operates by determining a plurality of pre-defined accessibility patterns each of which correspond to one or more user interactions by a user with a mobile device. Sensor data indicating that a user is unable to hold the mobile device steady is received. A first pre-defined accessibility pattern that corresponds to the indication that the user is unable to hold the mobile device steady is identified. A modification to a user interface is determined, and the user interface is modified in accordance with the determined modification corresponding to the first pre-defined accessibility pattern.
