“HOME” button with integrated user biometric sensing and verification system for mobile device
A mobile device having a HOME button with integrated user biometric sensing comprises a casing, a touchscreen, a HOME button and a camera/scanner module. The touchscreen is mounted on the casing and simultaneously acts as a display panel and a touch-sensitive digitizing input pad. The HOME button is mounted on the casing, and at least a portion of the HOME button is formed of an optically transparent material forming an aperture or lens for transmitting optical images through the HOME button. The camera/scanner module is disposed below the HOME button adjacent the aperture, and includes a housing, a lens, a photo sensor and signal wires which operatively connect the scanner/camera module to sensing/security circuitry disposed within the casing. When a user presses the HOME button with a fingertip, the lens array focuses an image of a fingerprint from the top surface of the HOME button onto the photo sensor.
1. A mobile device having a HOME button with integrated user biometric sensing, the mobile device comprising:
a casing;
a touchscreen mounted on a front side of the casing, the touchscreen acting as a display panel and, at the same time, acting as a touch-sensitive, digitizing input pad;
a HOME button movably mounted on the front side of the casing to move relative to the casing, at least a portion of the HOME button being formed of an optically transparent material so as to form a first lens for transmitting optical images through the HOME button from a top surface to the bottom surface;
a camera/scanner module disposed below, and spaced apart from, the bottom surface of the HOME button adjacent the first lens, the camera/scanner module being attached to the casing so that it does not move with the HOME button, and the camera/scanner module including a housing, a second lens, a photo sensor and signal wires which operatively connect the scanner/camera module to sensing/security circuitry disposed within the casing;
wherein the first lens of the HOME button and the second lens of the camera/scanner module form a lens array; and
wherein, when a user presses the top surface of the HOME button with a fingertip, thereby moving the HOME button relative to the camera/scanner module, the lens array focuses an image of a fingerprint of the fingertip from the top surface of the HOME button onto the photo sensor.
2. The mobile device having a HOME button with integrated user biometric sensing in accordance with claim 1 , wherein the mobile device is a smartphone.
3. The mobile device having a HOME button with integrated user biometric sensing in accordance with claim 1 , wherein the mobile device is a tablet device or table computer.
4. The mobile device having a HOME button with integrated user biometric sensing in accordance with claim 1 , wherein the mobile device is a handheld device.
5. The mobile device having a HOME button with integrated user biometric sensing in accordance with claim 1 , wherein after the lens array focuses an image of a fingerprint of the fingertip from the top surface of the HOME button onto the photo sensor, the photo sensor sends signals representative of the user's biometric data to the sensing/security circuitry of the mobile device.
6. The mobile device having a HOME button with integrated user biometric sensing in accordance with claim 5 , wherein after the photo sensor sends signals representative of the user's biometric data to the sensing/security circuitry of the mobile device, the mobile device compares the user's biometric data to previously stored biometric data corresponding to on or more authorized users of the mobile device and/or accounts accessible via the mobile device.
7. The mobile device having a HOME button with integrated user biometric sensing in accordance with claim 6 , wherein the comparison of the user's biometric data to previously stored biometric data corresponding to one or more authorized users is performed entirely within the mobile device.
8. The mobile device having a HOME button with integrated user biometric sensing in accordance with claim 6 , wherein the comparison of the user's biometric data to previously stored biometric data corresponding to one or more authorized users is performed at least partially via communication with an external networked device.
9. The mobile device having a HOME button with integrated user biometric sensing in accordance with claim 8 , wherein the external networked device is a security server.
