UMC (ver 0.2)

3/5 (1)

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.

4/5 (1) is a new giant, guys. But not in CAPCTHAs. Yes, must say, it’s nice, and hard to beat, but color model is not the only way to separate specific chuncks. It’s possible to separate letter chuncks from background chunks basing in it’s parameters, firstly – position and shape.
