BARRERA-RAMIREZ, John Fredy. Information encryption using optical processing. Rev. acad. colomb. cienc. exact. fis. nat. [online]. 2022, vol.46, n.178, pp.68-89.  Epub 07-Set-2023. ISSN 0370-3908.  https://doi.org/10.18257/raccefyn.1597.

In this contribution, the most significant advances in the area of information encryption using optical processing are discussed with an emphasis on advances in noise reduction and elimination. The theoretical description of a compact encryption system and the results of its experimental implementation are presented. Additionally, the inclusion of personalized information containers to protect information and retrieve it free of noise is also explained evidencing the potential of the compact security system. Finally, the perspectives of the research area are presented.

Palavras-chave : Information encryption; Optical processing; Data protection; Noise-free retrieval.
