Systems and methods for authentication code entry in touch-sensitive screen enabled devices
Systems and methods for authentication code entry in touch-sensitive screen enabled devices are disclosed. In one embodiment, a method for entering data to a data entry device comprising at least one computer processor and a touch-sensitive screen may include (1) the touch-sensitive screen sensing a first input comprising at least one finger touch; (2) the touch-sensitive screen sensing a release of the first input; (3) the at least one computer processor determining a first number of finger touches in the first input; and (4) the at least one computer processor using the first number of finger touches to identify a first portion of an authentication code.
1. A method for entering data to a data entry device comprising at least one computer processor and a touch-sensitive screen, comprising:
the touch-sensitive screen sensing a first input comprising at least one finger touch;
the touch-sensitive screen sensing a release of the first input;
the at least one computer processor determining a first number of finger touches in the first input;
the touch-sensitive screen sensing a second input comprising at least one finger touch;
the touch-sensitive screen sensing a release of the second input;
the at least one computer processor determining a second number of finger touches in the second input; and
after a predetermined period of time in which the touch-sensitive screen does not sense a touch, the at least one computer processor automatically calculating a sum of the first number of finger touches and the second number of finger touches, wherein the sum represents a value in an authentication code.
2. The method of claim 1 , further comprising:
the at least one computer processor rejecting the first input or the second input in response to the first input or the second input, or the sum of the first input and the second input being invalid.
3. The method of claim 1 , wherein a manner of receiving the first number of finger touches and the second number of finger touches is part of the authentication code.
4. The method of claim 3 , wherein the manner of receiving the first number of finger touches and the second number of finger touches comprises the first number of finger touches and the second number of finger touches.
5. The method of claim 3 , wherein the manner of receiving the first number of finger touches and the second number of finger touches comprises a location on the touch-sensitive screen at which at least one of the first number of finger touches and the second number of finger touches are received.
6. The method of claim 3 , wherein the manner of receiving the first number of finger touches and the second number of finger touches comprises a touch pressure on the touch-sensitive screen at which at least one of the first number of finger touches and the second number of finger touches are received.
7. The method of claim 3 , wherein the manner of receiving the first number of finger touches and the second number of finger touches comprises a timing of receipt of the first number of finger touches or the second number of finger touches.
8. A method for entering data to a data entry device comprising at least one computer processor and a touch-sensitive screen, comprising:
the touch-sensitive screen sensing a first input comprising at least one finger touch;
the touch-sensitive screen sensing a release of the first input;
the at least one computer processor determining a first number of finger touches in the first input;
the touch-sensitive screen sensing a second input comprising at least one finger touch;
the touch-sensitive screen sensing a release of the second input;
the at least one computer processor determining a second number of finger touches in the second input;
the touch-sensitive screen receiving a third input comprising at least one finger touch;
the touch-sensitive screen sensing a release of the third input;
the at least one computer processor determining a third number of finger touches in the third input; and
after a predetermined period of time in which the touch-sensitive screen does not sense a touch, the at least one computer processor automatically calculating a sum of at least the first number of finger touches, the second number of finger touches, and the third number of finger touches, wherein the sum represents a value in an authentication code.
9. A data entry device comprising:
a touch-sensitive screen;
a memory; and
at least one computer processor;
wherein:
the touch-sensitive screen senses a first input comprising at least one finger touch;
the touch-sensitive screen senses a release of the first input;
the at least one computer processor determines a first number of finger touches in the first input;
the touch-sensitive screen sensing a second input comprising at least one finger touch;
the touch-sensitive screen sensing a release of the second input;
the at least one computer processor determining a second number of finger touches in the second input; and
after a predetermined period of time in which the touch-sensitive screen does not sense a touch, automatically calculating a sum of at least the first number of finger touches and the second number of finger touches, wherein the sum represents a value in an authentication code.
10. The data entry device of claim 9 , wherein the at least one computer processor rejects the first input or the second input in response to the first input or the second input, or the sum of the first input and the second input being invalid.
11. The data entry device of claim 9 , wherein the touch-sensitive screen senses multiple touches at a plurality of locations.
12. The data entry device of claim 9 , wherein a manner of receiving the first number of finger touches and the second number of finger touches is part of the authentication code.
13. The data entry device of claim 12 , wherein the manner of receiving the first number of finger touches and the second number of finger touches comprises the first number of finger touches and the second number of finger touches.
14. The data entry device of claim 12 , wherein the manner of receiving the first number of finger touches and the second number of finger touches comprises a location on the touch-sensitive screen at which at least one of the first number of finger touches and the second number of finger touches are received.
15. The data entry device of claim 12 , wherein the manner of receiving the first number of finger touches and the second number of finger touches comprises a touch pressure on the touch-sensitive screen at which at least one of the first number of finger touches and the second number of finger touches are received.
16. The data entry device of claim 12 , wherein the manner of receiving the first number of finger touches and the second number of finger touches comprises a timing of receipt of the first number of finger touches or the second number of finger touches.
