System and method of secure data entry

Abstract

A computational device having a user interface is disclosed, the user interface enables a user to securely enter data into the computational device. In particular, the user interface may include a user input portion and a user output portion. The user input portion may be partitioned into a number of input zones, each having a data value associated therewith that when engaged by a user causes the data value associated with the engaged input zone to be provided as input to the computational device.

         22 . A method of securely receiving user input at a computational device, the method comprising:
 detecting a first user pinch gesture at a user input of the computational device, the first user pinch gesture having a first size;   correlating the first user pinch gesture to a first selection based on the first size of the first user pinch gesture;   detecting a second user pinch gesture at the user input of the computational device, the second user pinch gesture having a second size that is different from the first size; and   correlating the second user pinch gesture to a second selection based on the second size of the second pinch gesture.   
     
     
         23 . The method of  claim 22 , further comprising:
 conditioning the first selection and second selection as input data for the computational device; and   transmitting the input data to an authentication module for comparison with authentication data.   
     
     
         24 . The method of  claim 23 , wherein the authentication module is contained within the computational device. 
     
     
         25 . The method of  claim 22 , further comprising:
 determining, for the first user pinch gesture, a first value of a user input parameter of interest;   determining, for the second user pinch gesture, a second value of the user input parameter of interest; and   determining an average value of the user input parameter of interest based, at least in part, on the first and second values of the user input parameter of interest.   
     
     
         26 . The method of  claim 22 , further comprising:
 altering a size of an input zone for the user input based on either the first size or the second size.   
     
     
         27 . The method of  claim 22 , further comprising:
 altering a space between input zones between the first user pinch gesture and the second user pinch gesture.   
     
     
         28 . A computational device, comprising:
 a user interface including a user input portion and a user output portion;   a processor; and   a computer-readable medium coupled to the processor, the computer-readable medium including instructions configured to enable the processor to detect a first user pinch gesture at the user input portion then correlate a size of the first user pinch gesture to a first input, determine a first data value corresponding to the first input, cause the first data value to be displayed via the user output portion, detect a second user pinch gesture at the user input portion then correlate a size of the second user pinch gesture to a second input, wherein the size of the first user pinch gesture is different from the size of the second user pinch gesture, determine a second data value corresponding to the second input, cause the second data value to be displayed via the user output portion, determine that a user has discontinued the second user pinch gesture, and in response to determining that the user has discontinued the second user pinch gesture, condition the second data value as input data for the computational device.   
     
     
         29 . The device of  claim 28 , further comprising a communication interface configured to transmit the second data value to a networked device. 
     
     
         30 . The device of  claim 28 , wherein the user output portion is physically separated from the user input portion such that the data values displayed via the user output portion are not viewed through the user input portion.
