Innovative Encryption System Using Holograms and AI - Science of the day Jan 30, 2025

Researchers have developed a groundbreaking optical encryption system that combines holograms and artificial intelligence to create, what they say is an uncrackable level of security. This innovative approach could significantly enhance the protection of digital currencies, healthcare data, communications, and more. The system encodes information as a hologram, which is then scrambled when sent through a small container of "turbulent media" like ethanol. A neural network is used to decrypt the information, generating a decryption key that can only be created by the owner of the encryption system.

The research team, led by Stelios Tzortzakis from the Institute of Electronic Structure and Laser, Foundation for Research and Technology Hellas, and the University of Crete, discovered that using holograms to encode a laser beam result in a completely and randomly scrambled beam and "the original beam shape could not be recognized or retrieved using physical analysis or calculation". This method provides a highly reliable encryption system, even in harsh conditions.

The researchers demonstrated the effectiveness of their system by encrypting and decoding thousands of handwritten digits and other shapes, achieving an accuracy rate of 90-95%. They plan to further develop the technology by adding additional levels of protection, such as two-factor authentication, and exploring cost-effective alternatives to expensive, high-power lasers.
