Click type verification code implementation method

Abstract

The invention provides a click type verification code implementation method. The method comprises the following steps: a, randomly extracting and executing M graphic files from a graphics library and displaying the M graphic files in a verification code display area; b, randomly extracting N coloring schemes from a coloring base to fill the graphics in the verification code display area, wherein N is equal to or less than M, and recording the ID of the color; c, randomly extracting the graphic in certain color, and determining the key of the verification code according to the ID of the color of the graphic and the shape parameter of the graphic; d, giving a prompt message of the verification code for the user, and verifying the content of the verification code according to the click action of the user. Multiple times of random operations increase the solving difficulty and improve the safety of the verification code. The click type verification code implementation method can be clicked on a computer by a mouse, and is also suitable for a touch type mobile terminal. The click type verification code implementation method uses a graphic mode, the operation is novel, simple and intuitive, and the user experience and the acceptance are enhanced.

Description

technical field [0001] The invention relates to the field of electronic information verification, in particular to a method for realizing a click-type verification code. Background technique [0002] Captcha (CAPTCHA) is a public automated program that distinguishes users as computers and humans. Verification codes are used to prevent malicious cracking of passwords, swiping tickets, flooding forums, and swiping pages; verification codes can effectively prevent a hacker from using a specific program to brute force the continuous login attempts of a specific registered user to damage user information security. The use of verification codes is a common method for many websites. A series of randomly generated numbers or symbols are generated into a picture, and some interference is added to the picture. The user can identify the verification code information with the naked eye, enter the form and submit it to the website for verification. Only after the verification is successf...

Problems solved by technology

After research, this method has the following defects: (1) There is no substantial difference between the randomly displayed characters in the verification code picture and the existing verification code picture, and the difficulty of program cracking is the same as before; (2) The mobile terminal screen is inherently small, and the verification picture The effect area and button area occupy a certain amount of space, and the clickable area left for the verification code picture display becomes smaller, and the user experience is not friendly enough.
