Oh, thank you for your visit.
I’m very sorry that my site is just meant for Japanese people …
Er, well, it’s an extension of CCaptcha.
It was originally a fairly small extension, just with some additional flag, font, image rendering method and random string generator for Japanese. It was not very hard to implement.
But with the introduction of the client side verification, it has become a very ugly thing.
CCaptcha and CCaptchaAction has undergone a significant change because of the hash code used in the client side validation.
And, to my shame, I had to copy and paste almost all the lines from the original source to that of my extension. Still, I think it is easy to make this kind of extension based on CCaptcha and CCaptchaAction.
You know, I’m using Hirakana characters for it. They are the most basic characters for Japanese so that even a 5 years old child can read and write. It’s really easy to read for Japanese people.
And because my string generator shows strong favor to ‘HA’, ‘HI’, ‘HU’, ‘HE’, ‘HO’ over other characters, the generated string tends to become a funny phrase evoking a feeling of, say, exhausted laughter. I hoped that reloading the captcha image can be a good time killer.
So it’s a very user friendly captcha(although it’s just for Japanese people), and hopefully very harsh for spam robots.
