The third incarnation of Kyivstar Captcha is much easier then previous. In general – nothing to speak about. It’s almost the same as old UMS and first KS CAPTCHAs – see OCR demo at ocr-research.org.ua.
New version of UMC CAPTCHA is much better then previous (see demo). Char overlapping is great. BUT – it’s random there, so, sometimes there is no overlaping at all. And, of course, the char color. Thank you very much for making overlapped chars with different colors. Due to this feature overlapping means nothing, and gives no additional obfuscation. Must say that readability went down – it’s now not too easy to read it correctly. If you have any question, do not hesitate to contact us.
Super-easy CAPTCHA. Can be beaten easily. Weak noise, helpful color model.
