It allows the patients to create, manage, control and share their health information with other users like their family, friends and also the health care providers. In recent days, a PHR service is to be hosted by third-party cloud service provider’s to enhance its performance. There have been privacy issues while outsourcing patient’s health data to cloud servers, that is not only because cloud providers 8, but due to an enormous number of cloud data issues happened in lat few years. In this paper, we use blowfish algorithm in order to avoid these security issues. An elevated scale of patient’s privacy is guaranteed.
