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

A method for entering authentication value data to a data entry device that comprises at least one computer processor and a touch-sensitive screen, comprising:

• the touch-sensitive screen sensing a plurality of contacts with the touch-sensitive screen;
• the touch-sensitive screen sensing an entry gesture on the touch-sensitive screen;
• the at least one computer processor determining a number of touches sensed by the touch-sensitive screen in a period between the sensing of the plurality of contacts with the touch-sensitive screen and the sensing of the entry gesture;
• and
• the at least one computer processor using the number of touches to represent a value in an authentication code.

A data entry device for receiving authentication code data, comprising:

• a touch-sensitive screen;
• a memory;
• and
• at least one computer processor;
• wherein:
• the touch-sensitive screen senses a control touch on the touch-sensitive screen;
• the touch-sensitive screen senses a release of the control touch from the touch-sensitive screen;
• the at least one computer processor determines a number of first touches sensed by the touch-sensitive screen in a period between the sensing of the control touch and the sensing of the release of the control touch;
• and
• the at least one computer processor uses the number of first touches to represent a value in an authentication code.
