Abstract

Currently the popularity of wearable devices is on the increase and along with the development
of clouds and cloudlet technology, there has been an ever-increasing need to provide better
medical care. The processing sequence of medical data primarily includes data collection, data
storage and data sharing, etc. Traditional healthcare system often requires the delivery of medical
data to the cloud, which involves users’ sensitive information. Practically, medical data sharing
is a critical and challenging issue. In this paper, a novel healthcare system with de-duplication is
proposed and implemented incorporating the flexibility of cloudlet. The functions of cloudlet
include privacy protection, data sharing and de-duplication. Firstly, the Number Theory Research
Unit (NTRU) method is used to protect data during transmission of user’s body data collected
from wearable devices to the Cloudlet . Those data will be transmitted to nearby cloudlet in an
energy efficient fashion. Secondly, a new trust model to help users to select trustable partners
who want to share stored data in the cloudlet is presented. The results demonstrate the
effectiveness of the proposed scheme.
