Area of Science:

• Optics and Photonics
• Computational Imaging
• Information Security

Background:

• Digital holographic microscopy (DHM) is advancing biological research with 3D imaging capabilities.
• Secure storage and retrieval of large digital hologram datasets present challenges for cloud computing.
• Existing methods may lack efficiency or robust security for managing multiple encrypted holograms.

Purpose of the Study:

• To propose a novel scheme for secure and efficient storage and retrieval of multiple encrypted digital holograms.
• To leverage phase encoding multiplexing and binary phase masks for data security and access control.
• To enable independent management of encrypted hologram groups within a cloud environment.

Main Methods:

• Utilizing phase encoding multiplexing to combine multiple encrypted digital holograms.
• Employing binary phase masks as unique keys for hologram decryption and retrieval.
• Applying Hadamard matrices for their orthogonality properties to ensure independent data management.

Main Results:

• Demonstrated a secure method where encrypted holograms are accessible only with the correct binary phase mask key.
• Showcased the independent storage, retrieval, and management of multiplexed hologram groups.
• Verified the effectiveness of Hadamard matrix orthogonality in preventing interference between hologram sets.

Conclusions:

• The proposed scheme offers a secure and efficient solution for managing encrypted digital holograms in cloud services.
• Independent data operations (search, add, remove) are achievable without impacting other hologram groups.
• This method facilitates the scalable and secure handling of increasing volumes of 3D imaging data.
