Security challenges associated with big data in health care system

Abstract

The way organisations handle, evaluate and leverage information in any sector has essentially altered with big data. Healthcare is one of the most promising fields where big data can be used to create a change. In this paper, as applied to the healthcare industry, we surveyed the state-of-the-art security challenges in big data, assessed how security issues arise in the case of large healthcare data, and discussed ways to address them. We concentrated primarily on the lately suggested anonymization and encryption techniques, their strengths and constraints, and envisaged future directions for studies.
