MEDICAL IMAGES AND ITS SECURITY USING CHAOTIC AGORITHM

摘要

Medical images are most an important role of many diseases to proper diagnosis. Medicalimages are essential for many diseases diagnosis, disease progress monitoring, injuries identification, etc.The medical images are recorded by using X-ray images, CT-scan images, MRI- scan images, etc.Therefore, the security of medical images is important and inferior. However, the importance of securityof medical images is paramount to avoid mishandling moreover; the conventional cryptographic algorithmsare unable to provide robust security. Hence, an innovative algorithm has been developed to provide robustsecurity to medical images to avoid mishandling. Further security improvement for medical image todeveloped an algorithm of making a simple and effective chaotic system by using a difference of the outputsequences of two same existing one-dimension (1D) chaotic maps. Simulations and performance evaluationsshow that the proposed system is able to produce a one-dimension (1D) chaotic system with better chaoticperformances and larger chaotic ranges compared with the previous chaotic maps. The innovativealgorithms have been addressed several conventional methods limitation.
