Picture passwords to protect yourself from hackers

The alphanumerical Passwords are easy for hackers to crack in and get information from the protected areas.

In recent days there are some spyware programs that can detect your password, remember them and then send it to its programmer - who ofcourse is going to misuse it in his favour.

A group of researchers have come up with a solution. Their system that uses one clear and easily recognizable image and another that is a highly pixilated, unclear version of the original.

When creating a new password or changing an old one, the system provides the legitimate user with the clear image. But during the authentication phase, the system shows the user the unclear image, along with a number of decoy images.

The legitimate user who should now be familiar with the image will easily detect the unclear image but the hacker cannot.
