Abstract
A method for inputting an access code via temporal variations in the amount of pressure applied to a touch interface is disclosed. The method facilitates the input of access codes such as passwords, personal identification codes, and the like in a manner that is indiscernible (via either sight or sound) to third parties thereby reducing the possibility that the access codes may be copied or stolen and used a third party to gain unauthorized access to a system or function.
Claims45
A method for inputting a code by temporally varying the amount of pressure applied to a touch interface wherein the code may be used to enable a function, the method comprising the steps of
- sensing temporal variations in pressure applied to the touch interface;
- encoding the sensed temporal variations in pressure to generate a single code based on the sensed pressure over the temporal period;
- and
- comparing the generated code with a stored code template to determine if the generated code and the code template match within a predetermined tolerance.
A program of instructions storable on a medium readable by an information handling system for causing the information handling system to execute steps for inputting a code via a touch interface of the information handling system, the steps comprising:
- sensing temporal variations in pressure applied to the touch interface;
- encoding the sensed temporal variations in pressure to generate a single code based on the sensed pressure over the temporal period;
- and
- comparing the generated code with a stored code template to determine if the generated code and the code template match within a predetermined tolerance.
An information handling system, comprising:
- a processor for executing a program of instructions on the information handling system;
- a memory coupled to the processor for storing the program of instructions executable by the processor;
- and
- a digitizer pad coupled to the processor for sending temporal variations in pressure applied thereto;
- wherein the program of instructions configures the information handling system to input a code via temporal variations in the amount of pressure applied to the digitizer pad.
An information handling system, comprising:
- means for executing a program of instructions on the information handling system;
- means coupled to the executing means, for storing the program of instructions executable by the executing means;
- and
- means, coupled to the executing means, for sensing variations in pressure applied to a digitizer pad;
- wherein the program of instructions configures the information handling system to input a code via temporal variations in the amount of pressure applied to the digitizer pad for inputting a password.
