METHOD FOR SECURING COMMUNICATION BY SELECTING AN ENCODING PROCESS USING A FIRST COMPUTER BASED UPON ABILITY OF A SECOND COMPUTER AND DELETING THE PROCESS THEREAFTER

A method of enhancing network security is provided for a communication session initiated between a first computer and a second other computer. From the first computer to the second computer in communications therewith a process for securing communications therebetween is transmitted. One such process is a biometric characterisation process for characterising fingerprints. The process is for execution on the second computer and is selected to be compatible therewith. Communications from the second computer to the first computer are secured using the transmitted process on the second computer and using, on the first computer, a compatible process to the transmitted process. The host computer can modify or replace the process or data particular to the process before each session, during a session, or at intervals.
