Patent

CA 2571450

A secure input system and method are provided for protecting data transmitted between an input device such as a keyboard and a destination device such as a personal computer (PC). A first secure module is used for intercepting data transmitted by the keyboard to the PC, and the first secure module operates on the data to produce a protected output. A second secure module is used for receiving the protected output from the first secure module and returning the protected output to its original form. The original form of the data may then be forwarded by the second secure module to the PC for use thereby. The system enables a secure communication channel between the keyboard and the PC without requiring additional drivers or software to configure the PC to accept such protected data.
