Abstract

The invention provides a method for generating verification codes as well as a method and device for verification, wherein the method for generating the verification codes comprises the following steps of: selecting specific geographic elements; generating a verification map containing specific geographic elements and a verification condition taking the positions of the geographic elements on the verification map as an object; and obtaining the verification codes sent to a user by labeling the verification condition on the verification map. By virtue of the mode, the attack resistance of the verification codes can be effectively enhanced.

Description

【Technical field】 [0001] The invention relates to the field of computers, in particular to a method for generating a verification code, a verification method and a device thereof. 【Background technique】 [0002] Most websites on the Internet generally require users to register on their websites and obtain related services by logging in. However, with the development of network technology, there is a "robot program" that can easily realize automatic registration and login actions on various websites, resulting in a large number of non-real accounts. These accounts not only waste a lot of server resources, but also There may be interference with real accounts, such as sending spam to real accounts, etc. In order to prevent the automatic registration method from generating a large number of non-real accounts, verification code technology is produced accordingly. [0003] A captcha is a fully automated process that distinguishes between a computer and a human user, usually in ...
