Study: image-based passwords are less secure
Provides image-based password access to the operating system via the graphic, click picture.

It may not be safe passwords based on the image is weak as many thought at first, so this type of password can be difficult on the penetration by method used, according to a recent study.

And started talking about the picture-based passwords since its adoption in the operating system Windows 8 as one of the options, so the user can select an image and then accessing the system via clicking on certain points within the image or draw circles and lines around specific areas within the image specified by the user.

According to the study published by the “first dokline” researcher “Sophos” digital security solutions specialist, image-based passwords are less secure than other types of passwords, password-based image can be very strong.

“Dokline” in his study that the picture-based passwords might be weak, but this depends on the number of “gestures” that are used and the number of “points of interest” in the image. And the term “point of interest” to the faces of people or animals or buildings and other items in the photo that users usually chosen as points for clicking on them or draw circles around to open the device.

The study showed that Microsoft had developed a formula for the number of passwords that can be extracted from a single image based on gestures and points of interest. Thus, the more points of interest and more gestures in the picture, the more is the password.

The study indicated that the type of gestures used image can increase the difficulty of counterfeiting. For example, the circle of the click, the line more difficult. So the password consists of five gestures, all clicks will be easier to guess a password consisting of five gestures all fonts.

The use of image-based password in Windows 8 also does not eliminate the password must be a traditional resort in case of failure of the user to access the system after five failed attempts.
