Win8/Win8.1 picture password

Computer shop news: Although we often be warned when creating passwords on the Internet, please do not use excessive passwords or always use the same password, but a large number of people They all adopted a direct disregard of attitude. In fact, even if we use a password with a high security factor, hackers can still get user passwords in a variety of ways.

In 2011, Microsoft introduced a cryptographic technology that combines image and touch-screen gestures in Win8. Microsoft has claimed that this password method allows users to have 11,5550,9083 passwords that can be created, which will be much safer than PIN numbers or text passwords.

This sounds like a perfect way, but the reality is not. Recently, a research team from Arizona State University, Delaware State University, and GFS Technologies found that users who use Microsoft's password-setting technology generally upload their own photos and then often choose Some specific points in the picture, such as a person's nose, eyes, etc., set a gesture password.

The survey results show that in the survey of 685 Windows8 users, 60.3% of users will choose these "specific points" to set passwords, only 8.9% will choose not in the pictures. Obviously “point” to set the password. The researchers then attacked the passwords through the algorithms they created, and the results broke through 48% of the computers.

It seems that this perfect password technology is not as we think, the research team suggested that Microsoft should create a picture password strength meter for this password, let the user judge the picture gesture password that he created. Whether the safety strength of the device is high enough.
