ABSTRACT:
A random noise generator is included in the drive circuit supplying power to a system indicator that emits optical signals. The random noise generator generates a random noise signal that is introduced into a signal input to the drive circuit so that data or covert channel information is not recoverable from the optical signals emitted by the system indicator.
