Method for password input based on UNICODE coding

Abstract

The invention relates to a method for password input based on UNICODE coding. The method comprises the steps of classifying password characters and specifically dividing the password characters into a number and symbol class, a capital letter class, a minuscule class, a graphics class, a language class and a printed number class; setting the well classified password characters on an input panel, and inputting a password by clicking on the characters on the input panel; and each time one password character is input on the input panel, randomly rearranging the positions of the characters on the input panel to improve password input safety. According to the method for password input based on UNICODE coding, a special input device is not required, the method is as convenient as current text password input, and the method is compatible to a current text password input scheme.

Description

technical field [0001] The invention relates to a password input method based on UNICODE encoding. Background technique [0002] In recent years, with the rapid development of information technology, especially the rapid development of mobile Internet, people rely more and more on information resources. They not only obtain various information resources from the Internet every day, but also store their own information. Or share on the web. This information contains a large amount of private information of individuals or enterprises and institutions, such as personal bank account information, corporate property reports, or various policy documents of institutions, etc. These private information can only be guaranteed through legally authorized access. Security of such information. A commonly used authorization scheme is identity authentication. At present, the most widely used identity authentication method is to enter the user name and password for identity authentication...

At the same time, these passwords have less password space and are more vulnerable to brute force cracking

Although the password space of these text passwords has 95 N (N is the length of the password), but in fact most people prefer to use simple numbers or small letters or numbers plus lowercase letters, so the password space is usually only 36 N , it can be seen that this password space is much smaller than the actual password space, and is more vulnerable to brute force cracking
