We all know them when we see them, but mostly we don’t know the name. We use it to verify if you are a human being or not. I’m talking about CAPTCHA, the characters and numbers you have to enter when you sign up for something. But to make it harder for the computer to decode what’s on the image, they use several tricks, like in mine, using multiple colors. As a users we mostly find them iritating, basicly because we mostly can’t read them, but are there good sides about the fact that these images are getting very hard to read?
Well the fact that we can’t read them is due to the fact that computers are able to read them, so what should be our protection, is now falling apart and becomes a research project which goal it is to read images.
This can be useful but if computers are able to read images we do, security features like CAPTCHA won’t work any more. So the question is: are we willing to learn computers to read images and there for lose a fine piece of security?
I don’t think CAPTCHA is our ultimate security feature, so I’m willing to lose this security feature. If computer are able to read images we do, this can be very productive, not only think about image compression, but also about book scanning and all sorts of thinks.
