Abstract

Abstract: Technologyis enhancing each and every day especially in the field of InformationTechnology and data is very momentous elements. Due to the reasons such as therapid growth and spread of network services, mobile devices, and online userson the Internet leading to a remarkable increase in the amount of data. Almostevery industry is trying to cope with this huge data. Big data phenomenon hasbegun to gain importance. However, it is not only very difficult to store bigdata and analyse them with traditional applications, but also it haschallenging privacy and security problems. So we proposed system will classifythe files in two main categories i.e. Hot files and Cold files. To avoidbottleneck at server end the replicas of hot file will created and stored on differentservers. This accession is drafted to magnify privacy protection scope withinliquid ate time constraints. Proposed approach aims to selectively encrypt dataand use privacy classification methods under timing constraints.
