Abstract: A method, a system and a computer program product for expediting activation of contactless cards. An application on a computing device is executed upon the computing device detecting a contactless card to be located within a predetermined distance of the computing device. The computing device stores one or more computing device activation keys. The contactless card is an inactive contactless card. The stored computing device activation keys are accessed upon verifying one or more user authentication keys received in response to the executing. One or more contactless card activation keys are received. The contactless card activation keys are stored by the contactless card. The contactless card is activated based on a determination that the received contactless card activation keys match the stored computing device activation keys.

Sensor data corresponding to one or more user interactions with the mobile device is received, and a detected accessibility pattern indicating a visual impairment of the user is identified. The plurality of items are split into both a first screen and a second screen with larger font relative to the original screen, and the original screen is replaced with the first screen.

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.

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: 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: 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: Disclosed herein are system, method, and computer program product embodiments for verifying a document. An embodiment operates by receiving an initial image of a document and identifying a first imperfection on a feature of the document. Thereafter, the feature of the initial image is segmented into a first and second partially overlapping segment corresponding to a first and second portion of the feature, respectively. Subsequently, the feature's first portion is determined to be free from the first imperfection, and the first imperfection is identified in the feature's second segment. After receiving a second image of the document including the feature's second portion, the feature's second portion in the second image is determined to be free from a second imperfection. As a result, an image of the feature is created based on the first and second portions of the feature derived from the initial and second images, respectively.

The method can include triggering the camera to capture an image of the first object.

Abstract: In some implementations, a device may obtain an image of an object using a camera of the device and identify at least two corner points from a set of corner candidate points closest, respectively, to at least one corner of a bounding shape used to generate the set of corner candidate points. The device may validate the at least two corner points by determining that at least one edge length between the at least two corner points is within a threshold size of a corresponding edge of the bounding shape. Furthermore, the device may automatically trigger image capture based on satisfying predetermined conditions related to the identified at least two corner points.

The device may detect lines in the image, and may identify edge candidate lines by discarding one or more of the lines. The device may identify intersection points where lines, included in the edge candidate lines, intersect with one another. The device may identify corner candidate points by discarding one or more points included in the intersection points, and may identify a corner point included in the corner candidate points. The corner point may be a point, included in the corner candidate points, that is closest to one corner of the bounding rectangle. The device may perform perspective correction on the image of the document based on identifying the corner point.
