Security of Personal Bio Data in Mobile Health Applications for the Elderly

Abstract

Mobile devices used for heath can be used anywhere including homes or offices, thanks to their mobility and portability. Moreover since they are used for monitoring bioinformation as well as medical services in hospital, there is an increasing possibility of the leakage of personal bio data, which in turn increases the possibility of spoofing that data. Therefore, it is critical to establish countermeasures for privacy protection. More specifically, there is an increasing need for secure transmission of personal bio data between mobile health applications and health servers which archive personal bio data. Thus in this study, the authors implemented a system which transmits personal bio data (e.g. blood pressure, blood pressures and weight, etc.) to the server safely without saving it in the mobile devices using MD5 and Spritz. To verify the security of the implemented system, the authors spoofed data and succeeded in detecting all spoofed data.
