Embodiment Construction

[0014] The preferred modes of the present invention will be described in further detail below in conjunction with the examples.

[0015] Such as figure 1 As shown, a method for generating a graphic verification code includes the following steps:

[0016] S1. The system first selects two original images containing numbers or letters from the gallery inside the system, superimposes the two original images to form a verification code graphic, and saves the verification code graphic in the system.

[0017] S2. Add the background, interference lines and interference pixels to the two original images respectively, and then superimpose them to form the bottom layer.

[0018] S3. Cover multiple layers of interfering layers including dynamic pictures on the lowest layer to form a graphic verification code.

[0019] The invention proposes a method for generating a graphic verification code. Compared with the existing method for generating a graphic verification code, this method super...

Abstract

The invention discloses a graphic verification code generation method. The method comprises the following steps: S1, selecting two original graphs from a graph library in a system by the system, superposing the two original pictures to form a verification code graph, and storing the verification code graph in the system; S2, adding backgrounds, interference lines and interference pixels for the two original graphs and superposing the two original graphs to form a bottommost graphic layer; and S3, covering the bottommost graphic layer with a plurality of interference graphic layers to form a graphic verification code. According to the graphic verification code generation method proposed by the invention, the two graphs are superposed to form the verification graph, so that the difficulty in program identification is increased; and the method proposed by the invention can effectively increase the difficulty in automatic verification code program identification and improve the attack resistance of the system.

Description

technical field [0001] The invention belongs to the technical field of computer information, and in particular relates to a method for generating a graphic verification code. Background technique [0002] With the development of network technology, various services have been widely used on the network. While these services have brought a lot of popularity to the website, they have also brought many false users such as "network robots". These visits brought by false users consume valuable network bandwidth, occupy a large amount of website resources, and interfere with normal website business. In order to distinguish which of the users who visit the website are real and valid users and which are generated by the program, people use verification code technology. The so-called verification code is to display some information composed of numbers, letters or text on a picture, and at the same time use interference technology to make people recognize the information, but the pro...
