Abstract

The invention discloses a method for generating a verification code picture. The method comprises the following steps of: acquiring current verification code parameters including user set parameters and random parameters; generating an initial verification code picture according to at least one of the user set parameters and at least one of the random parameters; selecting a background picture at random from a pre-built background picture storage according to background picture selection parameters in the random parameters; acquiring a random selection area from the background pictures according to area selection parameters in the random parameters; and filling characters and backgrounds of the initial verification code pictures by using the random selection area to generate a final verification code picture. The invention also discloses a device for generating the verification code picture.

Description

technical field [0001] The invention relates to the technical field of Internet security, in particular to a method and a device for generating a verification code picture. Background technique [0002] With the increasing popularity of Internet applications, its market position is becoming more and more important. Some people try to make or use "keyboard" software on the open platform of Internet services to automatically fill in various login forms on the Internet, so as to achieve The purpose of sending a large amount of spam. In the field of Internet technology, a public fully automatic program that can distinguish whether the user behind a certain request is a computer or a human is usually used to avoid the security risks caused by the "registration machine". form. [0003] At present, the application of verification code pictures is relatively common. For a generated verification code picture, the user in front of the computer can easily get the answer that needs to...
