An implementation of privacy security for PHR framework supporting u-healthcare service

PHR is protected from being viewed without your consent or authorization. Therefore the security technology must be used by the system who offers PHRs. Security of health records primarily encompasses privacy and confidentiality. In this paper, we implemented PHR's privacy and confidentiality within the layered components of our PHR framework and then evaluated the performance of our implementation. Our implementation stores securely XML-based personal health records using XML security, created on a local machine and by using the owner's certificate and then placed on a repository server, and permits access to selected records only by the authorized users. According to the experimental result, our effort for the security cost reduction is more required because the security cost is about 73% of the total cost.
