Overview

This research demonstrates high visual fidelity in embedding secret medical data, suggesting robust data security in healthcare.

Key Points

  • The system achieves high visual fidelity with PSNR greater than 30 dB, ensuring clear medical images.
  • Evaluation scenarios confirm low data loss with a Bit Error Rate of approximately 0 across various conditions.
  • By integrating role-based access control, the system allows secure validation for doctors while safeguarding patient data.
  • Significant configurations resulted in a PSNR of 33.01 dB, proving the effectiveness of the proposed encryption method.
