User terminal, method and device for bank counter transactions

Abstract

The invention provides a user terminal, method and device for bank counter transactions. The device comprises a shell provided with data interfaces, a displayer and a keyboard. The displayer is connected with a teller terminal through the data interface and used for synchronously displaying a password input interface on the teller terminal; the keyboard is connected with the teller terminal through the data interface and used for allowing a user to input a password. According to the user terminal, method and device for the bank counter transactions, the problem that the account password is prone to being stolen due to the fact that the user can not monitor the password input interface of the teller terminal in the prior art is solved and account information safety of the user is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a bank counter transaction user terminal, method and device. Background technique [0002] At present, when a bank teller handles business for a user, the user's transaction information, especially the interface for entering the user's password is not transparent to the user. In the existing mode, the password keyboard is generally connected to the teller PC through a serial port line or a USB port line. After the user enters the password, the subsequent actions processed by the counter system are invisible to the user. Therefore, the following security problems are likely to occur : [0003] 1) The teller may take advantage of the loophole that the user cannot know the specific situation of the counter system. When handling deposits, withdrawals, or transfers for the user, they use the password input error as an excuse to ask the user to repeatedly enter the password, thereby...

AI Technical Summary

Problems solved by technology

[0003] 1) The teller may take advantage of the loophole that the user cannot know the specific situation of the counter system. When handling deposits, withdrawals, or transfers for the user, they use the password input error as an excuse to ask the user to repeatedly enter the password, thereby affecting the user's account. Do some illegal withdrawals, transfers, or early withdrawals

[0004] 2) There are some equipment test transactions in the counter system of some banks. If the design of these transactions is not perfect, it is only considered to return the plain text of the password when testing the password keyboard so that the tester can compare whether the password returned by the system is consistent with the entered password. Vulnerabilities could be exploited to steal customer passwords

[0005] Therefore, there are very serious security risks in the handling of bank counter business at present.
