It is funny that we are still using these old systems in CAPTCHA and reCAPTCHA. This week, NuCaptcha launched a video captcha offering. They have solved the readability and sweat labor issues that have come about. It's a true security offering that also improves input accuracy to 99%. http://Nucaptcha.com http://Nucaptcha.com Disclosure: I've advised with NuCaptcha on a pro bono basis.

    But you didn't say that. You said -> It's a true security offering that also improves input accuracy to 99%. !!!1!11ONE! If you want to plug something on HN, first you need to disclose that you are doing some advertising. (kudos, you did this) And second, you need to explain, without weasel words, how and why it's a good solution for the problem. Example of me plugging mongodb despite it only being marginally to the topic: http://news.ycombinator.com/item?id=1471516 http://news.ycombinator.com/item?id=1471516 [Deleted previous comment because I misremembered the thread I was replying to when I wrote it]

That's an interesting technique, but it seems like the human-detection is based more around it being a flash-based solution than any sort of obfuscation. e.g., if the text is always red, and always the same font (judging from the examples only), a screen capture of this would be far easier to decode than a regular captcha™. A flash-running bot should have a pretty easy time breaking it. Granted, the current state of the captchas™ is kinda bad.

  sigh. you don't even appear to need flash, the swf apparently just downloads an mp4 that's actually just a concatination of flash params exposed in the initial page request. from there one would be able to crack the captcha even easier by using the fact that the captcha persists across many frames of the video in various orientations/perturbations (the first character is touching the second character on top for half the video and then on the bottom for the other half, or so for example) gasp there's in addition to the mp4 and a completely different gif served with each request (To offer support for those without flash installed, of course!) that would provide even more data for figuring out the three red letters that persist across most frames of both animations...... :( edit--the three combinations of letters(captcha solution) across the mp4 version, the gif and the mp3 appeared to all be different voice recognition against the mp3 would be fun

Oh my god that's an absurdly terrible idea. Using Flash for a Captcha seems like overkill. They couldn't come up with a more lightweight Captcha?
