Thinking of CAPTCHAs
This is our first public article about building a mighty CAPTCHA, you can read it here. We hope to add more articles in nearest time, thank you for reading us.
Site was updated
Yes, we know that site was freezed for a long time, but now we have improved it, and seems like now we have an ability to keep it actual. Thanks to all who was waiting.
Kyivstar SMS sender v0.2
Kyivstar (one of the biggest mobile service provider in Ukraine) has changed it's CAPTCHA.
I don't realy know why, but I hope they found our site and understood the problem. Understanding
is good, but rushing is bad. Instead of think about how strong CAPTCHA should be built they just
made primitive changes. It's now in 100 times stronger then was, but still is easy to beat. Another
primitive CAPTCHA was implemented at UMC (biggest competitor of KS). And it's still there!
New set of weak CAPTCHA
After some time of browsing the web we found a set of new CAPTCHAs which must take a place in a Weakness list. Some of them are small and local, but it also contain a world wide famouse systems. Due to a self-confidence of webmasters we will have a lot of places where OCR may be successfully applied.
