Problems solved by technology

However, this method is not flexible enough. In the use of physical stores, there will be a phenomenon of centralized and frequent card swiping. If this method is adopted, after each transaction is completed, it is necessary to wait for another 30 seconds before the next transaction, which seriously affects the collection. Therefore, a protection method for PIN input of POS machines that can not only protect PIN input but also avoid affecting user experience is needed

Abstract

The invention provides a POS machine PIN input protection method and device, a storage medium and a POS machine. The method comprises the steps of setting two parameters for detecting the total numberof times of PIN input and the sum of consumed time, so as to switch to a PIN input display state for a user to input a PIN, and enabling the PIN to serve as a barrier for preventing PIN exhaustion. Whether the POS machine is manually exhausted to input the PIN code or not is judged by combining the total PIN input frequency and the consumed time sum, exhaustion is prevented from being limited byrigid setting of interval time, and the PIN input frequency within a certain time period cannot exceed the preset frequency in a flexible mode; the PIN input can be protected, and the influence on theuse experience can be avoided.

Description

technical field [0001] The present invention relates to the POS machine password security field, in particular to a PIN input protection method, device, storage medium and POS machine. Background technique [0002] Based on security design considerations, the POS terminal needs to prevent the cardholder's password from being cracked by exhaustive methods when entering the PIN. The conventional processing method is that the interval between each PIN input should not be less than 30 seconds. In this way, there will be no more than 120 times in 60 minutes. However, this method is not flexible enough. In the use of physical stores, there will be a phenomenon of centralized and frequent card swiping. If this method is adopted, after each transaction is completed, it is necessary to wait for another 30 seconds before the next transaction, which seriously affects the collection. Therefore, there is a need for a PIN input protection method that can not only protect the PIN input b...
