Abstract
A system is disclosed for controlling intelligible access to secured files by means of a user-memorized password in combination with a user-associated passport record. The passport record takes on two forms, one when it is physically secured within the workstation and a different second form when the passport record is in-transit. Log-in privileges are granted after a presented passport record passes a number of tests including digital signature authentication, and the ability to extract two different encrypted keys from the passport record. The in-transit record does not carry one of those two keys.
