To solve the security vs user experience problem, GeeTest developed AI-powered Slide CAPTCHA in 2012. Instead of visual recognition challenge, Powered by massive biometric data collected in the past 8 years, GeeTest built a self-adaptive defense model based on Graph Convolutional Networks (GCN).

TextCaptcha
TextCaptcha
The TextCaptcha service provides access to textual CAPTCHA challenges via a simple JSON or XML API over HTTP. The question is the textual challenge that should be presented to the user. The answers are the MD5 hashes of correct lower cased answers: you should be able to check responses from real users you challenge with the question against these checksums. A text CAPTCHA is more accessible to visually impaired users than their image-based alternatives like ReCAPTCHA. Using text is also more flexible if for example you need to present the challenge over a text-only channel like SMS or IRC. The problem with text CAPTCHAs is that they provide inherently more information than a distorted image. They are parseable, under the right conditions solveable. With the advent of contextual parsing tools such as Wolfram Alpha, such simple logic puzzles have become easier to solve programatically.Starting Price: Free -
