Cloud Computing In Health Care Data{2}

by Jorge R
The topic of my article is about implementing cloud computing into personal health care. The author explains that personal health records are (PHR) has increased in the recent years, this allows the patient to create, manage and control their personal health records through the internet. Using the internet has made it possible to easily access their data. Using the internet to access their personal files has made it possible for the patient to share their data to an health care provider, family members, and friends. Due the high cost of building and maintaining a PHR server companies have started to outsource to a third party cloud server. There is great debate over using these services due to privacy concerns and personal health records that are being exposed to unauthorized parties. A method to try and combat these issues is to ensure the patients have access to their files and an encryption process from the user to the cloud server. In order to ensure proper encryption from server to patient and vice versa, the article suggest on using a novel patient centric framework to a set of mechanisms for data access control. This ensures proper security measures when using a semi trusted cloud server. To achieve fine gain and scalable data access for PHRs the author suggests using (ABE) encryption measures to encrypt the patient’s files. This article does a good job when analyzing and explaining different measures in trying to ensure the highest level of security for the customers.

This article relates to the class because it shows what measures are needed to keep customer files safe when using an outsourced server. I would still want to see what other measures are implemented today to ensure better and higher security levels. A question that I ask myself is do we really want other people to handle our sensitive data, are the high cost a better solution in order to keep our files save. As a patient I don’t feel comfortable having other people looking at my sensitive medical records.
