A STUDY ON SECURITY OF BIG DATA STORED ON CLOUD PLATFORMS

Adhitya Rajagopalan

Abstract: Big Data is a field of work that is growing on a daily basis. There is a need to understand what it means, and its interpretation from a technical perspective. An insight into this could be provided by studying the Philosophy of Big Data [1]; the definitions and meanings regarding data that is ‘big’ in volume, velocity and variability. Cloud Computing is an upcoming service/platform that allows users to store their data online and reduces the need to invest in physical infrastructure that would be necessary to store the data locally. As the need for Big Data increases, so does the necessity to keep it secure. Data security, especially on the cloud, is a major challenge posed to specialists and the development of a cloud service that understands the threats posed to it and take counter-active measures to ensure the security of data stored on it is of utmost importance. This paper analyzes what Big Data and Cloud Computing are about, how large volumes of data are stored on the cloud platform and the security measures that are being followed, the encryption schemes like the Advanced Encryption Standard (AEN), Homomorphic Encryption, and Attribute Based Encryption.

Keywords: Big Data, Cloud Computing, Encryption Schema, Data Security
