| Abstract: | A system or method for encryption of data includes a light source, a
random optical element and a light detection element. The light source is
arranged to transmit an input data signal to the random optical element.
The light source is incident on the random optical element such that the
input data signal is randomly scattered by the random optical element to
generate an image at on the detector disposed at an output of the random
optical element. The image received by the detector is applied to a
compressive sensing algorithm to generate a transfer function. The
transfer function defines a relationship between the input data signal
and the image to enable estimation and reconstruction of the input data
signal. |
