Latest Patents
One of Johnson's latest patents focuses on access security control. This invention describes a system for access control, wherein a control card is presented to a control means. If the control card is authenticated, then access is gained. If it is not authenticated, access is not gained, the control card is retained, and an alarm may be sounded. The control card contains at least two means: (1) machine-readable indicia identifying the card, and (2) a random pattern of micro spots. This pattern is derived by direct copying, such as by a focused laser beam, from one of a plurality of different patterns retained in a bank of such micro patterns. Each micro pattern is identified by, and selectable in accordance with, different unique indicia, identical with the machine-readable indicia on the cards. In use, the control card is introduced into the control means, and the indicia are read. A master micro pattern corresponding to the indicia is selected from the bank. The card micro pattern and master micro pattern are compared. If the comparison is okay, the card is authenticated.
