Device and method for verifying passwords

Abstract

The invention relates to a device for verifying passwords, comprising a verifying unit and a displaying device. The verifying device is used for verifying passwords by comparing passwords inputted by an inputting unit and preregistered passwords. If the inputted content comprises the preregistered passwords or a password group which is formed by adding false passwords to true passwords according to the preset rule, the password passes the verification. The true passwords can be letters or numbers or special characters of the registered passwords, and the false password can be letters or numbers or special characters inputted randomly by the user or the combination of any two of the letters, the numbers or the special characters. The displaying device is used for displaying the content inputted by the inputting unit. When the registered passwords which are simple and are easy to remember are used, random passwords can be added to front and the rear of the true passwords according to the preset rule, thus the problem that the registered passwords are saw stealthily can be solved, and the psychological burden of inputting the registered passwords in the public place can be reduced. The method for verifying the passwords does not need to convert or remember again the dynamic passwords, thereby being easy to master. The device for verifying the password is easy to implement when being applied to an electronic product such as the automated teller machine (ATM) of the bank or a mechanical structure such as a full-mechanical dialing plate type password lock.

Description

technical field [0001] The invention relates to the technical field of password verification, in particular to a device and a password verification method for identity verification by inputting passwords in public places such as bank counters, ATM machines, safes and other special industries. Background technique [0002] At present, there are various password input and verification methods on the market, which can be mainly divided into two categories: [0003] One is to directly input a fixed-digit password, and the system judges whether it is correct or incorrect according to whether the input password matches. There are many applications such as electronic door locks, ATM machines, bank cards, etc. [0004] The second is to use dynamic passwords or other methods to input and identify passwords, such as Chinese invention patent CN200710200484.4 and Chinese invention patent CN01112565.9 [0005] Directly inputting a fixed-digit password is the most widely used password i...
