by jalb If you’re using captchas to protect your forms, or other forms of logic, you’re probably finding that you’re still getting spammed despite the captcha.
Well, here is a new idea for you to beat those captcha cracka bots, and some ways to implement it.
In short, we’re going to give bots different instructions than we give to humans. The bots don’t yet recognize and decode audio. Likewise they don’t yet handle video. And presumably they don’t crack every image on a page. So what you can do is record audio/video instructions or draw some instructions that the bot won’t be able to figure out – only the humans who understand you will make it through your form.
Some possible implementations of this :
1. Include several captchas on the page and indicate, via an audio recording, which one needs to be cracked. If they’re all cracked, or the wrong one is cracked, you know a bot did it.
2. Include captchas, logic questions and some other security device, and indicate via an audio recording that plays after a few seconds, which puzzle needs solving.
3. Again, include captchas but make a separate custom image/animated banner pointing to a random word or string on the page. The word or string is what needs to be entered in the captcha box.
