Abstract:
A hash of signal is determining by dithering and scaling random projections of the signal. Then, the dithered and scaled random projections are quantized using a non-monotonic scalar quantizer to form the hash, and a privacy of the signal is preserved as long as parameters of the scaling, dithering and projections are only known by the determining and quantizing steps.
