Summary
This study introduces a robust encryption method for 2D/3D objects using dual-plane digital holography. The dual-channel encryption ensures security, making reconstructed objects unrecognizable without both correct phase keys.
Area of Science:
- Optics and Photonics
- Information Security
- Computer Vision
Background:
- Digital holography offers advanced 3D imaging capabilities.
- Secure encoding of sensitive 2D/3D data is crucial in various applications.
- Existing encryption methods may have vulnerabilities.
Purpose of the Study:
- To develop a robust encryption method for 2D/3D objects.
- To enhance security by utilizing dual-plane in-line digital holography.
- To create a system resistant to unauthorized decryption attempts.
Main Methods:
- Employed a dual-plane in-line digital holography technique.
- Recorded two in-line digital holograms at distinct planes.
- Applied independent double random phase encryption to each hologram using mutually exclusive channels.
Main Results:
- The encryption method demonstrated high robustness against attacks.
- Reconstructed objects remained unrecognizable even with up to 75% of correct phase keys.
- Signal-to-Noise Ratio (SNR) and Mean Squared Error (MSE) metrics validated system security against blind decryption.
Conclusions:
- The proposed dual-channel holographic encryption method provides enhanced security for 2D/3D objects.
- The system effectively prevents unauthorized reconstruction, even with partial key information.
- Quantitative analysis confirmed the method's robustness and parameter sensitivity.
