Abstract: Portable well-being (Mobile-Health) has developed as anotherpatient driven model which permits continuous accumulation of patientinformation by means of wearable sensors, collection and encryption of thisinformation at cell phones, and afterward transferring the encoded informationto the cloud for storage and access by human services staff and doctors. In anycase, proficient and adaptable sharing of encoded information has been anextremely difficult issue. In this project, we propose a Lightweight Sharableand Traceable (LiST) secure versatile wellbeing framework in which tolerantinformation are scrambled end-to-end from a patients cell phone to informationclients. Rundown empowers productive catchphrase hunt and fine-grained get tocontrol of encoded information, underpins following of double crosser’s whooffer their look and access benefits for money related pick up, and permitson-request client denial. Rundown is lightweight as in it offloads the majorityof the substantial cryptographic calculations to the cloud while justlightweight operations are performed toward the end client gadgets. We formallycharacterize the security of LiST and demonstrate that it is secure withoutirregular prophet. We likewise direct broad examinations to get to theframeworks execution. In this system, DROPS methodology, divide a file intofragments, and replicate the fragmented data over the cloud nodes. Each of thenodes stores only a single fragment of a particular data file that ensures thateven in case of a successful attack, no meaningful information is revealed tothe attacker. The attribute authorities (AAs) are responsible for performinguser legitimacy verification and generating intermediate keys for legitimacyverified users
