Ask HN: What is best practice and the market leaders in CAPTCHA software?
I need to buy a CAPTCHA solution for a very high risk payments site, looking for recommendations on best practices in CAPTCHA today and who the market leading, enterprise scale vendors are
- retube 16y agoI'm not sure that a captcha should be considered part of your authorisation, identification or security framework. A captcha is just attempting to block out robots - it doesn't help you identify if a human user is who he says he is, or has the authorisation he says he has. No captcha is 100%. And they are trivial to break using human drones in India or China who solve hundreds an hour. That said, the best, and clear market leader in captcha technology is reCaptcha, now owned by Google (they paid $100m for it) http://www.google.com/recaptcha http://www.google.com/recaptcha
- rakkhi 16y agoI see it as a part of defense in depth so worthwhile being part of the framework but obviously not the only authentication and authorization component. Thanks for the reCaptcha recommendation
