Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0024] figure 1 It is a flow chart of verification by graphic verification code in the specific implementation manner of the present invention. Such as figure 1 As shown in , the process of passing graphic verification code verification includes the following steps:

[0025] Step 101, generate a graph, the graph only needs to include the verification code, the characters as the verification code can be numbers or letters, do not add noise, and do not need to distort or superimpose the verification code, such as figure 2 shown.

[0026] Step 102, generating an irregular segmented graph, such as a grid, and filling the difference, wherein the random density and random angle range of the irregular segmented graph can be set by the verification code generation program, such as image 3 shown.

Abstract

The invention discloses a method for verifying through a graphical verification code. The method comprises the following steps of: generating an irregular segmentation graph and performing difference filling; segmenting a graphical verification code according to a filling result of the irregular segmentation graph to generate not less than two parts; performing cross combination on not less than two parts which are generated by segmenting to generate a graph which cannot be subjected to machine identification; sliding a cursor in a predetermined range, wherein the graph which cannot be subjected to the machine identification slides along with the cursor, and not less than one predetermined coordinate value is in a predetermined range; triggering the predetermined coordinate value by the cursor; recovering the graphical verification code; and displaying a clear verification code. By adopting the method for verifying through the graphical verification code, a verification function can be realized, simultaneously user identification rate is improved, and input time cost is reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a verification method through a graphic verification code. Background technique [0002] The verification code (CAPTCHA) was first proposed in 2002 by Luis von Ahn, Manuel Blum, Nicholas J. Hopper of Carnegie Mellon University and John Langford of IBM, which generates a picture from a string of randomly generated numbers or symbols. By adding noise information to the picture, such as increasing the number of noise points and lines, increasing the degree of superposition of characters, increasing the degree of distortion, and increasing the number of characters that need to be judged, so that the verification information can be recognized by the naked eye of the user to prevent machine recognition (OCR), This effectively prevents batch mechanical operations for some programs, such as preventing users from using robots to automatically register, log in, or fill water, etc. ...
