In this paper, the system proposed a Lightweight Sharable and Traceable (LiST) secure framework in which tolerant information is scrambled end-to-end from a patient’s cell phone to clients. In this system, a sensor attached on the patient body to collect all the signals from the wireless sensors and sends them to the base station; they are able to sense the heart rate, blood pressure and so on. This system can detect the abnormal conditions, issue an alarm to the Patient and send an SMS/E-mail to the physician. The main advantage of this system in comparison to previous systems is to reduce energy consumption and security. In this system, DROPS methodology divides a file into fragments and replicates the fragmented data over the cloud nodes. Each of the nodes stores only a single fragment of a particular data file that ensures that even in case of a successful attack, no meaningful information is revealed to the attacker. The attribute authorities (AAs) are responsible for performing user legitimacy verification and generating intermediate keys for legitimacy verified users.
