Problems solved by technology

For the current picture verification code generation method that generates a static picture format, a malicious user can easily pull the entire verification code picture containing all characters through a machine program, and then use cracking methods such as character segmentation to extract information from the background noise. Extract all the characters, so that the picture verification code can be cracked
[0006] Therefore, the current method of generating image verification codes has a high risk of being cracked and is not very safe.

Embodiment Construction

[0021] 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 with reference to the accompanying drawings and examples.

[0022] The method provided in the embodiment of the present invention is: use the static picture containing the verification code text information as the first animation frame, use the selected background picture as the second animation frame, and alternately display the first animation frame and the second animation frame; The alternately displayed first animation frame and the second animation frame generate a dynamic picture, and the dynamic picture is used as a picture verification code. image 3 For an example flow chart of the method for generating a picture verification code adopted in the present invention, see image 3 , including the following steps:

[0023] Step 301: Use the static image containing the verification code text information as ...

Abstract

The invention embodiment discloses an image checking-code generating method which includes taking the static image with checking-code text information as the first animation frame, the chosen background image as the second animation frame and displaying the first animation frame and the second animation frame alternatively; using the alternatively displayed first animation frame and the second animation frame to generate a dynamic image, which can be taken as image checking-code. The invention also discloses an image checking-code generating device. The application of the invention can improvethe anti-decryption of the image checking-code.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for generating a picture verification code. Background technique [0002] With the development of network services, some people will use "robot programs" to use a large number of free resources on the network, which will greatly reduce server performance, such as mass spam, etc.; "In order to achieve the purpose of paralyzing the service; some people also use program means such as brute force cracking to carry out virtual property theft and so on. Therefore, image verification codes are more and more widely used as identification tools for distinguishing whether network service users are programs or human beings. [0003] The picture verification code is a picture containing characters. The characters in this picture are usually distorted or added with some noise under the premise of ensuring human visual recognition, so as to increase the difficulty of automatic pro...
