Abstract Medical images possess significant importance in diagnostics when it comes to healthcare systems. These contain confidential and sensitive information such as patients’ X-rays, ultrasounds, computed tomography scans, brain images, magnetic resonance imaging. However, the low security of communication channels loopholes storage systems hospitals or medical centres put these at risk being accessed by unauthorized users who illegally exploit them for non-diagnostic purposes. In addition improving systems, image encryption is a popular strategy adopted ensure safety against access. this work, we propose lightweight cryptosystem based on Henon chaotic map, Brownian motion, Chen’s system encrypt with elevated security. The efficiency proposed proved terms histogram analysis, adjacent pixels correlation contrast homogeneity energy NIST mean square error, entropy, number changing rate, unified average intensity, peak signal noise ratio time complexity. experimental results show that approach can achieve desired level encrypting image-based information.
