Picture password app for android description: 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.
