Method, device and equipment for auditing fraud by using all-in-one machine and readable storage medium

Abstract

The invention discloses a method, a device and equipment for auditing fraud by using an all-in-one machine and a readable storage medium. The method comprises the following steps: When fingers of an application user to be audited are detected to be in a preset position, triggering to turn on an LED flash lamp of the all-in-one machine; controlling to turn on a camera of the all-in-one machine, andcontrolling the camera to acquire a plurality of finger images of the application user to be audited under the irradiation of the LED flash lamp; performing photoelectric volume pulse wave signal analysis on the acquired finger images, and calculating the heart rate of the application user to be audited through photoelectric volume pulse wave signals of the finger images; with the calculated heart rate of the application user to be audited as an ordinate and the acquisition time of the corresponding finger images as an abscissa, depicting a heart rate change curve of the application user to be audited, and calculating the fraud probability of the application user to be audited according to the heart rate change curve of the application user to be audited. Whether a user has the fraud canbe known through the heart rate, so that the success rate of identifying the fraud is increased.

Description

Technical field [0001] The present invention relates to the technical field of fraud review, in particular to a method, device, equipment and computer-readable storage medium for fraud review of an all-in-one machine.
