Securing information by use of digital holography

TLDR

The paper presents an information security method based on digital holography. Encrypted images and decryption keys are stored as digital holograms, allowing electrical decryption via the key hologram. The technique enables secure storage and transmission, with experimental results confirming its effectiveness.

Abstract

An information security method that uses a digital holographic technique is presented. An encrypted image is stored as a digital hologram. The decryption key is also stored as a digital hologram. The encrypted image can be electrically decrypted by use of the digital hologram of the key. This security technique provides secure storage and data transmission. Experimental results are presented to demonstrate the proposed method.
