Embodiment Construction

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] With the iteration of technologies such as artificial intelligence, image recognition technology, and automated scripts, it is not very difficult for machines to recognize verification codes. Moreover, the current interaction method between computer equipment and people has not changed much. Under the current interaction method, a verification code that is easy for humans will...

Abstract

The present invention provides a verification code-based risk determination method, device, electronic equipment and storage medium, relating to the technical field of risk assessment, including sending a first verification code to a client to be verified; receiving first return data from the client to be verified , and judge whether the client to be verified is at risk based on the first returned data, wherein the first returned data includes the verification result and operation data based on the first verification code, as well as terminal hardware information and terminal environment information of the client to be verified; risk, send a second verification code to the client to be verified, wherein the second verification code is more complicated than the first verification code; receive the second return data for the second verification code, and determine the client to be verified based on the second return data The risk results at the end are widely applicable to various business scenarios, and on the basis of ensuring the accuracy of risk assessment, user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of risk assessment, in particular to a verification code-based risk determination method, device, electronic equipment and storage medium. Background technique [0002] Captcha is a technology commonly used on the Internet, mainly used to distinguish between humans and machines. Among them, there are various types of verification codes, including ordinary text recognition, picture information recognition, slider puzzle, text click, etc. As the offensive and defensive confrontation continues to escalate, the verification code has also been upgraded and iterated. In many scenarios with intense attack and defense, such as crawler confrontation and ticket grabbing, in order to prevent machines from participating, more complicated verification codes have to be used, but at the same time, the user experience is greatly reduced, and business losses are caused instead. Contents of the invention [0003] ...
