PC lock dongle - PIC16F628A
The PC lock device should have a lot of applications.
For example, the author implemented this lock at a friend’s Internet café.
Also, a small software company employs this versatile lock together with an OCX
incorporated into their software to prevent pirating and multiple software installations.
The author himself employs it on his PC’s to prevent his children from
giving him heart failure when they “accidentally” destroy valuable source code.
The software controlling the PC lock dongle is a resident utility, hiding
in the root of the operating system and waking up on startup. It also interfaces
with the PC lock dongle hardware via the serial port, exchanging data every second.
For the person that is fanatical about security of his or her files, this is
a cost effective solution.
