Researchers at the University of East Anglia have created an encryption method aimed at securing medical images for the NHS, enhancing protection against cyber threats. The system addresses vulnerabilities by securing individual images like X-rays and MRIs, even if hospital network defenses fail.

By leveraging chaos theory, it generates unpredictable cryptographic patterns that resist unauthorized access. The method can encrypt and decrypt images in two to four seconds, suitable for clinical environments. Pilot testing with NHS partners will assess its real-world performance and integration with current systems, aiming to safeguard patient data and improve healthcare cyber resilience.
