Method and device for outputting bar code of password

Abstract

The invention relates to a method for outputting a bar code of a password by using a cell phone or a display screen. In the invention, a corresponding conversion program of characters, numbers and bar codes is provided; the password is outputted by using the cell phone of the display screen in a bar code mode; and the bar code is received by using a common camera or a photoelectric bar code reader and is identified by the conversion program, wherein the bar code can be a one-dimensional bar code or a two-dimensional bar code. Because the two-dimensional bar code can be used to identify Chinese characters, letters and the like, the invention can widen the password selection range of any users, that is to say, Chinese characters, letters and the like can be used as characters or methods of password input. By the method for outputting the bar code of the password, the user can input the password just by adopting the cell phone or the display screen when entering various equipment requiring password input, and a program internally set in the cell phone or the display screen converts the password into the bar code.

Description

1. Technical field [0001] The present invention relates to methods and devices for securely performing cryptographic output (input). 2. Background technology [0002] At present, various devices (such as computers facing users, bank ATMs, and access control for door locks) and other computer security systems are common, and users need to remember various passwords, which are easy to forget and easy to input mistakes. There are still many risks of being peeped and resulting in loss when using the password set by oneself. Often, the bank card suffers the greatest loss due to peeping and theft. [0003] In order to solve the above-mentioned deficiencies, there have been many input methods of various passwords: [0004] CN200410024960.8 Mobile phone password system, the user sets multiple groups of passwords on the mobile phone, and the mobile phone controls the input and output of passwords, and directly enters and exits the security system protected by passwords, protection s...

Problems solved by technology

[0012] The push-button mobile phone password input method and system are used to solve the problem of low security in the existing mobile phone password input methods; the existing password input methods generally use N-digit numbers, and more passwords are set by users themselves. Generally, the user's birthday, phone number or the birthday number of the close person is used as the password input, which is easy to be cracked and has poor security.

If a complex password system is used, it is difficult to remember, causing users to need to remember various passwords, which are easy to forget and easy to input errors.
