Protecting Medical Data Over Cloud using an Effectual Authentication Model

Abstract

Abstract- Tele-medicine provides better on-demand service from various places. This technology is modelled to get rid of the distance based barriers and to enhance service accessing process in various rural communities. With cloud computing advancements, Medical based on-demand services (MoDS) in tele-medicine system are offered by Cloud Service Providers (CSP). CSP associates patients and medical personalities from various places with fidelity and confidentiality. However, healthcare data outsourcing over public cloud offers certain novel confronts on security. Even though, attribute based encryption process provides flexible access control, huge amounts of subscribed or unsubscribed patients are connected with cloud based medical services; offering membership management is expensive. Here, Secure-MoDS based protocol (S-MoDS) is anticipated to acquire dynamic authorization and authentication with improved efficiency and flexibility for medical services over telemedicine system. Subsequently, when patients intend to change their ordering service, it does not require any parameter updating for those patients. Here, a secure authentication mechanism has been constructed for distributed tele-medicine system that attempts to update patients’ private key separately. As well as, multiple authorities are involved to handle this system even in real time environment. However, private healthcare data, distributed database that are placed in cloud should show protection integrity. This may eliminate accidental misdiagnosis from inappropriate electronic health records that are circumvented by malicious users of internal cloud. Here, simulation is performed in MATLAB environment. The anticipated S-MoDS provides better trade off in contrary to prevailing attribute based encryption model in key generation and protocol performance.
