Abstract: Metasurfaces are a type of two-dimensional artificial microstructure material with subwavelength thickness, and their precise control ability over core optical parameters such as the phase, amplitude and polarization of light waves has demonstrated broad application prospects in the field of optical information processing. Holographic encryption technology records the light wave interference pattern of an object to achieve the encoding and encrypted storage of information. Its characteristics are large information capacity and high encryption security. Metasurface holographic encryption technology combines the excellent optical control performance of metasurfaces with the principle of holographic encryption. By designing specific metasurface structures, it achieves independent or coordinated phase modulation of light of different wavelengths and polarization states, thereby generating encrypted holographic images. This article introduces the use of metasurfaces to regulate electromagnetic waves of a single frequency band and a combination of bands, achieving hologram and information encryption. In the coming years, as nanofabrication technology continues to mature, we can look forward to the continuous emergence of new encryption algorithms and the in-depth advancement of interdisciplinary research. It is expected that holographic encryption technology based on metasurfaces will achieve significant breakthroughs in enhancing encryption capabilities, expanding application scope, and realizing system integration, providing more efficient and reliable solutions for the modern information encryption and security field.
