Data Security Management Scheme Based on Editable Medical Consortium Chain
Secure management of medical data is crucial for ensuring the security of patient privacy and effectively conducting medical treatments and related research.However,most existing medical data management solutions have the problems of low transparency,inadequate sharing and fail to secure patient privacy.By designing an editable blockchain model with a"main-side"chain structure,a secure and accountable healthcare data management scheme for healthcare consortium chain is proposed.Its main chain stores current information about the patient's electronic medical record,while the side chain records historical proof of modification,enabling the transparency and traceability of data management.Introducing chameleon hash function,secret sharing and verifiable signature technology,only verified system administrators of healthcare organizations are able to construct the com-plete trapdoor,which ensures the correctness and security of the medical data modification process.Security analysis and related experiment simulation show that,the proposed scheme performs well in computational overhead and communication load,as well as storage efficiency,which demonstrates its effectiveness and feasibility.
