Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] In the embodiment of the present invention, the natural background image is used as the background pattern of the verification code, and the color of the foreground text is adaptively selected, so as to ensure that the foreground and the background can be distinguished to ensure the user's recognition, and because the foreground color is flexible and changeable , can also increase the difficulty of cracking. In addition, in the embodiment of the present invention, a method of randomly intercepting sub-images may also be used to generate a natural background image, thereby increasing the cost and cost of cracking by using a violent method.

Abstract

The invention discloses a method for generating a picture verification code and a system for generating a picture verification code. The method includes: calculating the color distribution and brightness distribution of the natural background image, and determining the text color and text brightness for the foreground text respectively according to the calculated color distribution and brightness distribution; embedding the foreground text according to the determined text color and text brightness into the natural background image. After the application of the present invention, the generated picture verification code can bring better visual experience to users and is difficult to decipher.

Description

technical field [0001] The present invention relates to the technical field of network application (Application), and more specifically, the present invention relates to a method for generating a picture verification code and a 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. ...
