calabiyau Posted February 25, 2007 Share Posted February 25, 2007 If I set up an image verification system that generated three separate random strings and displayed them side by side, each in a different color and then instructed the user to enter the string of a specific color? Not sure how these bots operate, but do you think they would figure out the logic somehow, or know to scan each of the different colors separately?

Archadian Posted February 25, 2007 Share Posted February 25, 2007 just use pictures of letters and numbers like most PHPBB and PHPNUKE websites do. Link to comment https://forums.phpfreaks.com/topic/39987-would-this-stop-a-spam-bot/#findComment-193375 Share on other sites More sharing options...
calabiyau Posted February 25, 2007 Author Share Posted February 25, 2007 Well they are pictures of the numbers generated by php, but I thought there was ways they could scan the photos. Somebody told me that, but maybe they were just pulling my leg.

Archadian Posted February 25, 2007 Share Posted February 25, 2007 Well go to this somebody and slap the shit out of them, then use the pictures bots can only read numbers and letters, not pictures you can create images with PHP then as random 5-6 numbers and letters then save it as a picture.

calabiyau Posted February 25, 2007 Author Share Posted February 25, 2007 LOL...i guess i am a gullible person. I had images in my mind of these bots downloading your images, running it through some kind of scanning software that pulls the numbers out of the back ground and goes from there. crazy robots!

Jessica Posted February 25, 2007 Share Posted February 25, 2007 Uhm, maybe both of you should try doing some research. Those images are called CAPTCHA. They can be beaten by OCR, which is pretty much a bot scanning the image for numbers and letters.

calabiyau Posted February 25, 2007 Author Share Posted February 25, 2007 Yeah that's what I thought. So what do you think Jesirose? Would my method add some confusion to their efforts?

btherl Posted February 25, 2007 Share Posted February 25, 2007 It really depends on who you're up against. If you have a small user base, don't bother with advanced techniques of bot detection. If your images are sufficiently complex that someone would have to put some effort into defeating the mechanism, then you're already safe from 99% of spammers. Most of them want methods that work on hundreds of sites, or one large sites, and will not bother with a small site.
