Embodiment 1

[0017] In the system, the shortest password entered for the first time can be set according to the user's own choice to set the number of digits that are easy to remember, and the length of the password is set to 6 digits. The number of digits of the password is set to allow 2 incorrect input times for the password with the same number of digits, that is, 2 times of input is 1 round. and the fourth time) need to input a password whose number of digits increases regularly. Set the number of digits increased by each round of passwords to 1, and the increase rule is to adopt the method of increasing the order of the shortest password. The number of prohibited attempts is 6 times, that is, after the user enters the wrong password 6 times, the password will be locked, and the password entered again will be invalid.

[0018] The following is the password verification process of this embodiment:

[0019] A100. The user enters the password according to the prompts on the system inte...

Embodiment 2

[0036] In the system, the shortest password entered for the first time can be set according to the user's own choice to set the number of digits that are easy to remember, such as setting the password length to 6 digits. The number of digits of the password sets the allowable wrong input times of the password with the same number of digits to 1 time (the number of times of input in each round is one), that is, for a password with the same number of digits, if one input is wrong, the next time you need to enter a digit A password whose number increases regularly. The number of digits increased by each password is 1, and the increase rule is to adopt the method of increasing in reverse order of the shortest password. The number of forbidden attempts is 7 times, that is, after the user enters the wrong password 7 times, the password will be locked, and the password entered again will be invalid.

[0037] The following is the password verification process of this embodiment:

[...

Embodiment 3

[0058] In the system, the shortest password entered for the first time can be set according to the number of digits that are easy to remember according to the user's own choice. The length of the shortest password is set to 3 digits, and the length of the original password is 6 digits. In the prior art, all are generally entered. original password. The number of digits of the password sets the allowable wrong input times of the password with the same number of digits to 1 time, that is, for a password with the same number of digits, if you enter a wrong number once, you need to enter a password with a regular increase in the number of digits next time. The number of digits increased by each password is 3 digits, and the increase rule is to adopt the method of adding 1-9 numbers after the shortest password and sorting them in a circular manner. The number of prohibited attempts is 6 times, that is, after the user enters the wrong password 6 times, the password will be locked, a...

Abstract

The invention relates to a password authentication method which comprises: a first authentication step that authenticates at least a once entered password and a first set password; and a second authentication step that authenticates a password entered in a next round and a second set password when the first authentication step fails in the password authentication, wherein the second set password has more digits than that of the first set password. The password authentication method of the invention assists in solving problems in the prior art that: if a password is too long, it will be difficult for a user to remember, and if a password is too short, it will be easily cracked.

Description

technical field [0001] The invention relates to a password verification method, in particular to a password verification method whose password length needs to be changed. Background technique [0002] The technology with password verification function is widely used in real life, and provides a certain security guarantee for people's corresponding operations. Generally, the longer the password length, the higher the security level. Although a very long password has high security, it is difficult for the user to remember, and the input process is also very cumbersome, time-consuming and labor-intensive. Shorter passwords are less secure and are easily cracked, leading to password leaks. Contents of the invention [0003] In order to solve the problems in the prior art that the password is too long for the user to memorize, time-consuming to input, and the password is too short and easy to be cracked, the present invention provides a password verification method, which inc...
