Optical fingerprint anti-counterfeiting method and device and computer readable storage medium

Abstract

The invention provides an optical fingerprint anti-counterfeiting method and device and a computer readable storage medium, and the method comprises the steps: controlling an optical fingerprint module to carry out the continuous exposure and image collection of a fingerprint carrier in a process that the fingerprint carrier presses a fingerprint recognition region on a display screen; based on aplurality of fingerprint carrier images obtained by continuous exposure image acquisition, carrying out statistics on deformation process characteristic data of the fingerprint carrier; comparing andverifying the deformation process characteristic data with legal deformation process characteristic data representing deformation characteristics in a process of pressing the fingerprint identification area by a real finger; and when the verification is passed, determining that the current fingerprint carrier is a real finger. Through the implementation of the scheme of the invention, the true andfalse fingers of the fingerprint carrier to be identified in the actual use process are distinguished by combining the finger deformation process rule in the process of pressing the fingerprint identification area by the real finger, so that the technical implementation complexity is effectively reduced, the fingerprint anti-counterfeiting reliability is fully ensured, and the use safety of the terminal is improved.

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...
