Question

I tried different Java-related captcha solutions such as JCaptcha, SimpleCaptcha, etc. I am not satisfied. I could miss something. What I really like is something very similar to this one in terms of generated characters and look and feel.

Does anyone know of a Java solution generating an image VERY similar to the above one?

I also tried reCaptcha and don't like it. It often generates capcha code hard for people to type it right in the first try.

Était-ce utile?

La solution

The type of Captcha you presented has already been cracked. An attacker can pre-process the image, making it thinner, then thicker (eliminating all the little dots), center each character vertically, then run it through a common OCR.
