Abstract
In accordance with some embodiments, an apparatus for privacy protection is provided. The apparatus includes a random number generator providing a random number sequence. The apparatus also includes a key generator operable to receive the random number sequence and synthesize the random number sequence to generate a plurality of keys. The apparatus also includes a plurality of randomizing chains, each receiving a corresponding key from the key generator and providing a respective discrete random number sequence based on the corresponding key. The apparatus further includes output devices, each of which is connected to a respective randomizing chain to receive the respective discrete random number sequence and produces a respective output noise signal based on a function of the respective discrete random number sequence. The apparatus also includes interfaces mating the output devices with the input devices of a second device.
