Описание Picture Password

Picture Password is a new method of securing your device that allows you to use a combination of a number (0 to 9) and picture to unlock your device instead of typing a password. When enabled, instead of unlocking your device using a password, you’ll be shown a picture and a grid of random numbers. To unlock your device, tap anywhere on the screen and drag the number grid until your number is on top of a specific spot.
Picture Password not only provides you with a quick and easy way to unlock your device, it also helps prevent other types of attacks such as:
Smudge Attack – Picture Password always shows a random number grid whenever you unlock your device, which means you never follow the same pattern. In other words, because you always move your number from a different location on the grid, an attacker cannot establish a smudge pattern.
Shoulder Surf Attack – When using a simple password, someone could look over your shoulder while you enter it. Picture Password prevents this situation from occurring by drawing a random number grid and varying the size of the grid. For example, in addition to a random number grid, the grid size also randomly changes increasing and decreasing the amount of rows and columns to reduce the shoulder attack vulnerability.
Brute Force Attack – Picture Password addresses brute force attacks by limiting the number of guesses, varying the size, location, and pattern of the grid numbers and requiring minimum movement of the number grid.
