Sum the digits on the dies? 5 lines of openCV should do the trick
Find which of 3 (three!) extracts is a repeating pattern?? Could this be any easier? This sounds actually easier for a machine than for a human being!
- wraptile 3y agoI've been observing that the custom captcha process itself is a very good bot repellent because someone has to reverse engineer captcha behavior and most malicious actors actually don't know how to. Sprinkle a bit of obfuscation and your 2+2 captcha will be more effective than pages of traffic light selections.
- ThatPlayer 3y agoI've made a solver myself recently for a custom captcha, but I think it's more a testament of how bad the custom captcha was. The captcha was a 'select the right picture (singular)' type, and didn't have a nonce so I just attempted every single answer and would eventually get in. I was able to build up a database of correct answers before they fixed that.
- patmcc 3y agoIt's security through novelty. No one has bothered to write a bot solver for these yet. They will, soon enough, if it's protecting anything worthwhile, but that's some other engineers problem.
- amai 3y ago> Sum the digits on the dies? 5 lines of openCV should do the trick. Not so fast: First the images show dices with a mixture of dots and numbers. Second the images are not from the top, but at 45 degree angle. By that one can also see the numbers/dots on the side of the dices. Distinguishing numbers/dots which are on the side from ones on the top is pretty hard. The algorithm needs to have an understanding of the 3d structure of the dices in the image.
