An optical fingerprint anti-counterfeiting method, device and computer-readable storage medium

Abstract

The application provides an optical fingerprint anti-counterfeiting method, device and computer-readable storage medium. During the process of pressing the fingerprint identification area on the display screen by the fingerprint carrier, the optical fingerprint module is controlled to continuously expose the fingerprint carrier to collect pictures; based on continuous exposure The multiple fingerprint carrier images obtained by taking pictures, and counting the characteristic data of the deformation process of the fingerprint carrier; comparing and verifying the characteristic data of the deformation process with the legal deformation process characteristic data representing the deformation characteristics of the real finger pressing the fingerprint recognition area; When the verification is passed, it is determined that the current fingerprint carrier is a real finger. Through the implementation of the application scheme, combined with the law of finger deformation process during the process of pressing the fingerprint identification area with real fingers, the fingerprint carriers to be identified in the actual use process are distinguished between real and fake fingers, which effectively reduces the complexity of technical implementation and fully guarantees The reliability of fingerprint anti-counterfeiting improves the security of terminal use.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to an optical fingerprint anti-counterfeiting method, device and computer-readable storage medium. Background technique [0002] With the continuous development of terminal technology, the penetration rate of full-screen terminals is getting higher and higher. Due to the high screen-to-body ratio of full-screen terminals, the fingerprint recognition technology under the screen has also emerged as the times require. [0003] At present, optical fingerprint recognition technology, as a mainstream off-screen fingerprint recognition technology, is favored by the market due to its fast response speed and accurate recognition rate. However, with the popularization of this technology, fingerprint identification and cracking solutions including fingerprint imitation have emerged as the times require. Fingerprint imitation refers to duplicating the fingerprint of a legitimate u...
