About
ALTCHA is a modern security and privacy-focused platform built to defend web services from bots and abuse — without compromising the user experience. At the heart of its ecosystem is ALTCHA Sentinel, a next-generation threat detection and mitigation system designed to protect websites, APIs, and applications from automated attacks, spam, and other forms of abuse.
ALTCHA Sentinel stands out by combining adaptive machine learning, behavioral analysis, and smart verification techniques. It doesn’t rely on intrusive CAPTCHAs or outdated blocking tactics; instead, it works invisibly behind the scenes, analyzing traffic patterns in real time to identify and stop threats before they cause harm. Sentinel protects critical entry points like sign-up forms, login pages, and comment sections — all while keeping the experience seamless for real users.

About
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.
