Privacy Issues & Security Techniques in Big Data

Big Data, as the name suggests is a process of collection of information in a very large amount and storing it in a multidimensional database of various organizations and thereby performing Analytical operations on it to increase their efficiency and enhance their ability of decision making. Strategies can be made using this technology which uses real time using Big Data Analytics.

Also, in case if any on sanctioned user intends to cheat the organization with the valuable data stored at the database of the organization, the it can be detected at the instant it happens and so suitable measures can be taken against that unsanctioned user. Despite of having so many advantages, it has some limitations also. One of the main issues of concern of this technology is Privacy security. This paper focuses on identifying the threats related to data privacy information stored on the database of the organization and access control systems.
