Abstract

The invention discloses a method and a device for safety detection of a POS machine. The method includes steps: S1, setting safety trigger parameters; S2, the ultrasonic transmitter emits ultrasonic waves inside the POS machine; S3, the ultrasonic receiver receives the reflected ultrasonic waves; S4, according to the emission time of the ultrasonic waves emitted by the ultrasonic transmitter and / or The transmission frequency, the receiving time and / or reflection frequency of the ultrasonic wave received by the ultrasonic receiver, and the safety trigger parameters are used to determine whether the POS machine has been attacked abnormally. The device includes a POS machine shell, and the POS machine shell is provided with: an ultrasonic transmitter, an ultrasonic receiver and a processing module. The invention detects whether the shell of the POS machine is attacked abnormally through the ultrasonic technology, improves the reliability, controllability and stability of the security detection of the POS machine, thereby effectively guaranteeing the data security of the POS machine. The present invention can be widely used in various POS machines.

Description

technical field [0001] The invention relates to the safety monitoring of an electronically operated cash register, in particular to a safety monitoring method for a POS machine, and also relates to a safety monitoring device for a POS machine. Background technique [0002] POS machine is a sales terminal with non-cash settlement function, which is widely used in supermarkets, chain stores, hypermarkets, restaurants and other places. Because transactions involving bank cards have high requirements for its security performance, it is necessary to ensure that important data such as keys in the POS machine are not stolen. In order to standardize the security performance of POS machines, the Payment Card Industry Data Security Standards Committee has formulated the PCI certification standard. The PCI certification standard aims to strictly control data storage to ensure the security of payment card users' online transactions. [0003] At present, various POS machine shell protec...
