Method and device for realizing verification code based on track verification

Abstract

The embodiment of the invention provides a method and a device for realizing a verification code based on track verification. The method comprises the following steps: acquiring a user verification track which is inputted in the process of verifying a sliding operation on the basis of an appointed route in the verification code; utilizing a preset static parameter rule and a dynamic classifying rule to respectively verify if the verification track of the user accords with a natural person operation rule, wherein the static parameter rule means the conditions which a fixed parameter in the verification track of the user on the basis of the natural person operation rule needs to meet and the dynamic classifying rule means a dynamic classifier used for distinguishing whether the verification track of the user belongs to a natural person operation or a machine operation; judging if the verification track of the user is the natural person operation according to a verification result of the static parameter rule and the verification result of the dynamic classifying rule. According to the technical scheme, the method can resist against the technique for decomposing the verification code by singly using an image recognition technique, and meanwhile, the accuracy of distinguishing the natural person from machine can be promoted under the condition that the user experience is not influenced.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a verification code realization method and device based on track verification. Background technique [0002] Verification code: It is a fully automatic procedure to distinguish whether the user is a machine (computer) or a natural person. [0003] There is a pattern recognition input type verification code in the prior art. It randomly selects numbers or letters from the existing database, enters the corresponding numbers or letters from the keyboard, and the computer judges whether it is correct according to the input result. If it is correct, it will be recognized as a human operation, otherwise it will not be passed. With the rapid development of image recognition technology, the recognition of numbers and letters has become extremely simple. Because computer programs use image recognition technology to recognize these numbers and letters more and more accurately, makin...
