Electronic secure key lock in
cooperation with a central
information system
System of checking the secure distribution of personnel. It is a hardware system
which collaborating with the corresponding software, checks and allows or not
the passage of personnel inworking or domestic places. There are three solutions
given for same problem. The key for the certification is the information that
is contained on a simple telephone card. A group of data constitutes the 104
bits of the ROM. An another group of data is the picture that exists on the card.
We can check the luminous energy that goes through the holes punched in the body
of the card or read the photograph that exists on it. Both sides of the card
are scanned each one in a different way. One with a dot-to-dot scanning and one
with a lens and a high-resolution optic reader. All this system can function
in a network, or stand alone in the case where we simply want to make a lock
for our house. Using only the card to unlock the system is useless, because in
order to have someone access it needs keying the secure password.
