Captcha Technique

Do you still lay with Captcha? If you often surf in cyberspace and registration on a website, usually there will be security code which contains characters which must alphanumerik you fill in accordance with the drawings, if one then you have to repeat the charge. If it is correct then the registration stage would be successful. Security code that is named with the Captcha.

Scientists at Tel Aviv University is currently working on a new captcha technology that they think will be more difficult for hackers ditelusupi by robots. The new system relies on the ability of people to recognize the object when the object is moving, although this new system may be much more difficult to see than the usual picture.

"People have very specific skills that a bot can not yet mastered the computer," said Professor Danny Cohen-Or. "We can see what is called 'the emergence of image', when an object on the computer screen becomes recognizable when moving and identify these images in seconds.

"Although one can not see the images as objects in the background still punctate, moving objects will allow us to recognize and process it."

New synthesis techniques to produce 3D images such as those running or flying aircraft. This will allow developers to produce an infinite number of moving objects which would be almost impossible to be solved by computer algorithms.

The scientists warn that this experiment would take a little time before the results of research can be applied in the real world. But they are currently defining the parameters that identify the level of difficulty of perception of pictures that can be used in future web security technology.

"We do not claim that our research has been thoroughly resolved," said Professor Cohen-Or. "But we are taking steps in that direction, something that could generate captcha is far better, to highlight the major differences between human and robot.

Hopefully this research will result in a better way to be able to identify a user whether a human or a robot, without having to trouble us through this process later.
