PHP Web Ragnarok Captcha

Recommended Posts

Hello, It's me again, I've been doing some stuff lately and decided to share this thing

A bot captcha 

Written in PHP

It uses a set of 16 pictures

I've used PHP's GD library to generate the picture of items to click (grey set of 3 images to the right)

So, the challenge, really, is to click three images matching ones in the model.

Obviously, images appearing in the model and the order of images to chose from are random.

Obviously, chosen images disappear.

Once test passed or failed you will be shown the result....

Under appreciated because Gurus think this captcha is vulnnerable,

since the only methods I've used are

- Items to click is a plain image generated by gd

- GreyScale filter is applied to that image

 

Anyhow, picture to the right is generated by code and I have full control over it.

Should there be written a bot able to compare images and bypass this captcha,

I can add some random semitransparent text over generated image, some random pixels etc...

 

I really wanted this captcha to be fun to do, rather than

- some text to enter ( boring, annoying)

- logical problrm to solve ( might be a problem if the language problem is written on, is not the persons first language...)

Captcha is nice, and new design,

I haven't seen any RO server using RO related captcha yet.
