Method and system for managing passwords of ATM safes

Abstract

The invention provides an automatic teller machine (ATM) safe box password management method and system. The method comprises the steps that an automatic teller machine control (ATMC) can send password inquiring requests to an automatic teller machine view head (ATMVH) through a communication network; the ATMVH can inquire true passwords stored in a data base according to the password inquiring requests, can combine the true passwords and preset offset to generate transmission passwords according to a preset offset algorithm and can send password inquiring response message carried with ciphertext after the transmission passwords are encrypted; and the ATMC can analyze the password inquiring response message to obtain the transmission passwords displayed on a display module to enable a password manager to confirm the true passwords according to the transmission passwords, the preset offset algorithm and the preset offset. The ATM safe box password management method and system can achieve remote inquiry of safe box passwords, avoids password leakage risks caused by recoding passwords with a tally book / storage media, and saves labor and material cost. In addition, due to the fact that the transmission passwords rather than the true passwords are sent, password safety is further guaranteed.

Description

technical field [0001] The invention relates to ATM equipment, in particular to a management method and system for an ATM safe deposit box password. Background technique [0002] According to the relevant regulations of GB / T18789, the safe of ATM must have a mechanical lock, and the safe password on the mechanical lock is composed of three groups of two-digit numbers (11-89) in the specified range, such as 31, 45, 78 for a single safe password . When unlocking, the turntable of the mechanical lock corresponds to the set password by turning four times to the left, three times to the right, and two times to the left to open the safe. [0003] When the password manager wants to manage dozens or even hundreds of ATM devices, in order to accurately remember the safe password of each device, the password manager will record the password in the record book, and then carry the record book to the ATM device site. This method has the risk of the record book being stolen or lost, and...

AI Technical Summary

Problems solved by technology

This method has the risk of the record book being stolen or lost, and if multiple password administrators manage the same ATM at the same time, they need to be recorded separately, the workload is repeated and the risk of being stolen or lost is increased

In addition, since the recorded password is the real password of the safe, the security of the password is further reduced

[0004] Those skilled in the art may think of using a storage medium (for example: a notebook) to record the password of the safe, but this also has many problems such as manual recording, carrying of the storage medium, and low password security.
