Abstract:
1. A method of encrypting a set of data, the method comprising: generating an original set of data regarding a 3D input scene with multiple perspectives; generating a reference set of data; encoding the reference set of data; and combining the original set of data with the encoded reference set of data to generate an encrypted set of data; wherein the encoding of the reference set of data comprises phase encoding the reference set of data; wherein the phase encoding of the reference set of data comprises introducing a random phase into the reference set of data; and further comprising recording the encrypted set of data in a digital hologram; wherein the recording of the encrypted set of data in a hologram comprises recording the encrypted set of data in a hologram according to the equation: and wherein said φ is the encrypted phase and said A E (x,y) is expressed as is the encrypted amplitude.
