Embodiment Construction

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by 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.

[0034] In the embodiment of the present invention, using the characteristics of human eyes to observe things, suggestive lines and graphics can be used to see non-existing lines. The picture verification code generated by this idea increases the difficulty of machine recognition while reducing the Difficulty of recognition by the human eye.

[0035] see figure 1 , is an implementation flow of the method for generating a picture verification code provided in the first embodiment of the present invention, which includes the following steps:

[0036] In step S101, a...

Abstract

The invention is applicable to the technical field of verification code generation, and provides a method and system for generating a picture verification code. The method comprises the following steps: randomly generating verification code characters; randomly clearing part of the strokes of the verification code characters; processing the verification code characters whose partial strokes are removed into picture format verification code pictures. The method also includes the following steps: randomly generating verification code characters; dividing an area as the background area of ​​the verification code characters; filling the background region and the verification code characters in different ways; The background area and the verification code characters are processed into a verification code picture in picture format. The invention enables the verification code generated by the method for generating the picture verification code provided by the invention to reduce the difficulty of human eye recognition while increasing the difficulty of machine recognition.

Description

technical field [0001] The invention belongs to the technical field of verification code generation, and in particular relates to a method and system for generating a picture verification code. Background technique [0002] With the increasing popularity of computers and computer networks, the Internet has penetrated into all areas of people's work, study and life. Network development brings various challenges while providing convenience. Some people with ulterior motives will use robot programs to improperly use a large number of free Internet resources, such as mass spam, etc., which will greatly reduce server performance. There are also people who use the program to continuously send out service request responses to carry out "saturation attacks" to achieve the purpose of paralyzing the service. Some people even try to use brute force cracking and other means to steal virtual property. In order to avoid the above-mentioned malicious behaviors, it is very important to d...
