Abstract

We explore the possibility of communicating encrypted information using infrared metamaterials. We first describe our algorithm for encrypting a plain image in multiple cipher images, each corresponding to a different wavelength channel. Our scheme is designed so that an interloper will not be able to recover the image from the summed intensity or the individual channels. However, the intended recipient can easily reconstruct the image by performing a mathematical operation over the channels. We implement this scheme in a 4-channel infrared metamaterial and demonstrate image encryption and decryption.
