Problems solved by technology

[0002] Graphical unlocking passwords are the identity authentication methods for desktop and mobile devices. However, because the passwords selected by users are relatively simple and the repetition rate of the starting point is high, it is easy for attackers to crack user passwords. Therefore, the security of traditional graphic unlocking passwords is not high.

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] The invention discloses a graphic unlocking password authentication method based on a graphic addition algorithm, and the overall flow of the method is as follows: figure 1 Shown, more specifically:

[0027] Step 1, set the graphic unlock password interface, the specific implementation of this step is as follows:

[0028] (1a) Create an object array points representing the midpoint of the Jiugongge on the graphical unlocking interface, fill in the state state, abscissa x, and ordinate y of the midpoint of the Jiugongge as parameters into the elements of the object array points, and pass the...

Abstract

The invention discloses a pattern unlocking password authentication method based on pattern addition algorithm. The method of the present invention is as follows: (1) setting the graphic password nine-square grid interface, (2) setting the graphic password registration interface user and drawing the graphic, (3) passing the graphic into the background and obtaining the digital password through the algorithm label to complete the registration, (4) the user Enter the graphic to be verified and the digital password to judge whether the algorithm is satisfied to complete the verification. Based on the traditional graphic password, the present invention improves the security of the user password by adding an algorithm, increases the password space, and has stronger defense against shoulder-peeping attacks, dictionary attacks and brute-force cracking, and can be used on desktops , Identity authentication of the mobile terminal.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to an AGP (Algorithm Graph Password) method for identity authentication and identification of desktops and mobile terminals based on graph addition algorithms for graph unlocking password authentication. Background technique [0002] Graphical unlocking passwords are the identity authentication methods for desktop and mobile devices. However, because the passwords selected by users are relatively simple and the repetition rate of the starting point is high, it is easy for attackers to crack user passwords. Therefore, the security of traditional graphic unlocking passwords is not high. . [0003] The new graphic unlocking password scheme AGP has added an algorithm. After drawing the graphic unlocking password, the background will get numbers according to the algorithm. The background compares whether it satisfies the algorithm through graphics and numbers. In this case, compare...
