• a non-transitory storage medium;
• at least one processing unit;
• and
• one or more modules that are stored in the non-transitory storage medium;
• and are executed by the at least one processing unit, the one or more modules comprising instructions to:
• (a) randomly generate an unlocking sequence that includes one or more data combinations, each of the data combinations including a set of coordinates on the touch screen;
• (b) select an nth data combination from the unlocking sequence, and display an unlocking icon on a particular location of the touch screen according to the coordinates in the selected data combination;
• (c) detect a touch on the unlocking icon during a predetermined time period;
• (d) determinate whether all the data combinations in the unlocking sequence have been selected upon condition that there is a touch on the unlocking icon during a predetermined time period;
• (e) repeat steps (b) through (d) until all the data combinations in the unlocking sequence have not been selected;
• and
• (f) unlock the touch screen.

A non-transitory storage medium having stored thereon instructions that, when executed by a processor of an electronic device, causes the processor to perform a method for unlocking touch screens, wherein the method comprises:

• (a) randomly generating an unlocking sequence that includes one or more data combinations, each of the data combinations comprising a set of coordinates on the touch screen;
• (b) selecting an nth data combination from the unlocking sequence, and displaying an unlocking icon on a particular location of the touch screen according to the coordinates in the selected data combination;
• (c) detecting a touch on the unlocking icon during a predetermined time period;
• (d) determining whether all the data combinations in the unlocking sequence have been selected upon condition that there is a touch on the unlocking icon during the predetermined time period;
• (e) repeating steps (b) through (d) until all data combinations in the unlocking sequence have been selected;
• and
• (f) unlocking the touch screen.
