Method and System for Securely Unlocking a Touch Screen Device While Obfuscating a Password or a PIN Entry

Disclosed is a method and system for securely unlocking a touch screen device while obfuscating a password or a Personal Identification Number (PIN) entry. The method and system proposes a disc shaped data input area which is similar to a watch on a user interface of the touch screen device. The disc shaped data input area displays randomly arranged digits in two different colors. In total, there are 10 digits on the disc, wherein the digits range from 0 to 9. The arrangement of the digits changes each time a password input is invoked. In addition, function of the digits based on the color, makes it difficult for an onlooker to determine the password by viewing actions of a user of the touch screen device.

Fig. 1 illustrates a circular input area for entering the password.

As shown in fig. 1, the red colored input dot is present in the center of the circular input area with the digits 0 through 9 on an outer edge of the circular input area. Additionally, four black colored digits and six red colored digits are illustrated. The four boxes below the circular input area, as shown in fig.1, displays either an asterisk or some other character each time a password

digit is entered. The arrow is present besides the circular display area for enabling the user to delete an incorrectly entered digit. The method and system enables the user to reenter the password in case of an error, by tapping the arrow to delete an incorrectly entered digit.

The circular input area always displays four black colored randomly arranged digits and six red colored randomly arranged digits. Further, the display screen, digit colors and digit locations on the screen remains static while the user is in the process of entering the password.

The user drags the digits of the password from the outer edge into the red colored input dot one at a time in an order desired by the user. After the user finishes dragging each digit, either the asterisk or some other symbol is displayed inside the box present underneath the circular input area to display that a digit is selected. Here, only the red colored digits are effective digits. For example, 1, 2, 4, 6, 8, 9 are the effective digits in fig. 1.
