1. An electronic device for unlocking a touch screen, comprising:
- the touch screen; and
a processor, executing the following operations;
displaying a continuous circular boundary on the touch screen while the touch screen is locked upon detecting a first touch signal, wherein said first touch signal is on said boundary;
detecting a second touch signal on said boundary at a first relative distance from said first touch signal, while said first touch signal remains on said boundary;
changing a size of said boundary according to a second relative distance between said first touch signal and said second touch signal after at least one of said first touch signal or said second touch signal moves; and
unlocking the touch screen when a difference between the first relative distance and the second relative distance is larger than a predetermined value, wherein the first relative distance and the second relative distance are greater than zero.

Abstract
A method for unlocking touch screen, electronic device thereof, and recording medium thereof are disclosed. A graph with a boundary is displayed on a touch screen. Then two fingers touch the outside, the inside or the boundary of the graph and move outward or inward separately. Whether the touch screen of the electronic device is unlocked is determined based on whether the distance between the moved two fingers is larger or smaller than a default value, or whether the distance difference between the two fingers before and after moving is larger than a default value.
