AN APPROACH TO SAFEGUARD PRIVACY AND INTEGRITY OF DATA STORAGE IN MOBILE CLOUD COMPUTING

Abstract

Mobile cloud computing is a combination of mobile computing and cloud computing that provides a platform for
mobile users to offload heavy tasks and data on the cloud, thus, helping them to overcome the limitations of their mobile
devices, where data processing and storage can happen away from mobile device Although, cloud storage brings
convenience to mobile users, at the same time brings the certain risk to the security of their data as the user will have to
surrender the control of their data. Due to storing data on cloud there is an issue of data security, integrity and
confidentiality. To ensure the security of user's data in the cloud we propose an effective mechanism for data integrity and
confidentiality. The enhanced mechanism provide flexible security using different algorithms with key variation (depending
on sensitivity of file), Hash function (dynamic verification), CRCs for checking network transmission error and Group
policy providing low cost, less communication overhead and better security to the data stored on the mobile cloud.
