Unleashing 5D Chaos: Elevating and Securing High-Resolution Polarized Medical Imaging

Polarization and encryption play a crucial role in enhancing the security and quality of medical images. Polarization techniques help in improving image contrast, which is particularly beneficial in imaging modalities like optical coherence tomography and endoscopy. This enhances the clarity of critical medical images, aiding in more accurate diagnoses. Additionally, polarization-based imaging can be used to differentiate between healthy and diseased tissues, improving the efficiency of medical examinations. On the other hand, encryption ensures the confidentiality and integrity of medical images, which is vital for patient privacy. As medical images are transmitted over digital networks, encryption protects them from unauthorized access and cyber threats. Various encryption techniques, such as chaotic encryption, phase grating, and cyclic coding, can be employed to secure medical images without compromising their quality. Combining polarization with encryption can further enhance security by using polarization-sensitive encoding methods. This approach provides an additional layer of protection, making it difficult for attackers to retrieve or manipulate sensitive medical data.In this paper, we proposed a novel method of enhancing high-resolution medical images using polarization by eliminating glare. These polarized images are encrypted using a 5D Chaotic map in the next process. The combination of polarization and a 5D Chaotic map provides excellent encryption of the high-resolution medical images. By comparing with other methods, we proved that our techniques provide better results compared with some existing methods. Additionally, this is a fast process as it takes only 25ms to complete the entire process.
