Systems and methods for authentication code entry in touch-sensitive screen enabled devices

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 at least one computer processor uses the first number of finger touches to identify a first portion of an authentication code;
• the touch-sensitive screen senses, within a predetermined period of time from the release of the first input, a second input comprising at least one finger touch;
• the touch-sensitive screen senses a release of the second input;
• the at least one computer processor determines a second number of finger touches in the second input;
• the at least one computer processor uses the second number of finger touches to identify a second portion of the authentication code;
• the at least one computer processor calculates 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 the authentication code.

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 at least one computer processor using the first number of finger touches to identify a first portion of an authentication code;
• 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 at least one computer processor using the second number of finger touches to identify a second portion of the authentication code;
• the touch-sensitive screen sensing an entry gesture;
• and
• in response to the sensing of the entry gesture, the at least one computer processor 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 the authentication code.
