Area of Science:

• Optics and Photonics
• Information Security
• Data Storage Technologies

Background:

• Holographic data storage offers high density.
• Existing systems face challenges in balancing security and performance.
• Orthogonal-phase-code multiplexing (OPM) provides low crosstalk.
• Random-phase coding (RPC) enhances security but can increase complexity.

Purpose of the Study:

• To develop an encrypted holographic data-storage system.
• To integrate the security benefits of RPC with the efficiency of OPM.
• To maintain low crosstalk and minimal code storage requirements.

Main Methods:

• The proposed system combines OPM with a random-phase key.
• This hybrid approach leverages the strengths of both multiplexing techniques.

Main Results:

• The system achieves the security advantages of random-phase coding.
• It retains the low cross-talk performance characteristic of OPM.
• The solution minimizes code storage requirements.

Conclusions:

• The integrated system provides a robust solution for secure holographic data storage.
• This approach enhances data security without compromising storage efficiency or data integrity.
• The developed system represents a significant advancement in secure optical data storage.
