The invention's features include a switchboard, a centralized security interface, which interacts with a location recognition device at each remote location. Security is provided by secure and easily changeable location recognition device initialization, the transmission of a unique location security code from each location recognition device to the switchboard, and location recognition device immobility through the use of volatile memory. Unauthorized computer system access is prevented by a switchboard access protocol that uses a relationship between location security codes and personal identification codes to limit specific computer system users to specific remote locations and to lock-out, from computer system access, any remote location or analog thereof that the switchboard determines is being used by a hacker or other unauthorized user.Other References
