Abstract

An apparatus and method for device security are provided in which a fingerprint image is acquired on a touch screen and an authentication process is performed based on the first fingerprint image. Thereafter, a second fingerprint image is acquired and a difference between the characteristics of the first and second fingerprint images is determined, and a second authentication process is performed based on whether the difference is greater than a threshold.

Description

[0001] This application is a divisional application of a patent application with an application date of October 10, 2018, entitled "Equipment and Method for Ensuring Device Security Through Fingerprint Authentication", and application number 201880066926.7. [0002] This patent application claims priority to U.S. Nonprovisional Application No. 15 / 798,327, filed October 30, 2017, entitled "APPARATUS AND METHOD FOR DEVICE SECURITY," and The foregoing is assigned to the present assignee and is hereby expressly incorporated herein by reference. Background technique [0003] In devices with a fingerprint sensor, the fingerprint sensor can be used to authenticate the user. The authentication process may enable access to data or functionality that would otherwise be inaccessible to unauthorized users. [0004] A fingerprint sensor may reside, for example, under the touchscreen and be able to sense touches across the screen. It may also reside only under a portion of the touchscreen...
