Re: CAPTCHA image validation in web form

If its worth it for the hacker, there are some ways to bypass your captcha.
For example, a hacker can harness the human processing power of Amazon's
Mechanical Turk and even automate the entire process.

I'm not saying that captcha is dead, because it seems to lower the spam
volume from sites that use it. However, it may be only temporary relief.

maybe simple, or maybe useful idea:

the program shows an html with an image,
but the image is not an captcha, the image is an small photo: a boat in the
sea.

below the image, the question: please select the image:
and an select/combobox or check/radio with several possibilities:
_ ICE _ BOAT _ GIRL _ THE MOON _ FLOWERS _ GUITAR _ THE SUN

you get the idea, the user click in BOAT and voila,
only human can select the adecuate? ocr is unable at least.

maybe an low number of images are enough,
this can be made using RPG, no js code required.

too simple?

Guillermo.
