If you’ve got any sort of form on the internet, you’ll eventually have to protect yourself against bots. Whether it’s scalping tickets, comment sections, or even attacks on login forms, it’s important to differentiate between human and non-human traffic.
The most popular CAPTCHA service, Google’s reCAPTCHA, is a powerful tool, but has some notable downsides.
All verification requests go through Google's servers, making it a centralised system. Your site’s users don’t want to hand all their data over to Google if they don’t have to - the privacy concerns here are inevitable.
If you reach the levels of traffic that you’re probably aiming for, reCAPTCHA can quickly get very expensive.
Human verification is not the main aim of CAPTCHA for Google - data labelling is. Google is more than happy with supplying a poor user experience and letting false positives through, as long as it helps build their closed-source library of labelled images.
reCAPTCHA often blocks users who use VPNs, proxies, or Tor, mistaking them for automated traffic. Individuals who care about their privacy, often the most technical and valuable users, should not have their online experience damaged.
Prosopo CAPTCHA is decentralised, fully open source, and stores no user data. Transactions on the network are cryptographically secure and all infrastructure is fully distributed.
Simply put, Prosopo CAPTCHA is free forever, for all applications, regardless of traffic.
Prosopo isn’t building closed-source datasets and has no incentive to put image labelling first. We provide security against bots first and foremost.
Prosopo’s CAPTCHA is privacy-oriented and does not discriminate against users protecting themselves online with a VPN.
Prosopo CAPTCHA is a drop-in replacement for reCAPTCHA - setup couldn’t be more simple. Even though we’re in beta, we have a comprehensive setup guide here: Prosopo CAPTCHA Setup Guide.
