A SURVEY OF SECURE CLOUD STORAGE MECHANISM: CHALLENGES AND ITS SOLUTIONS

Cloud storage has been a boon for many organizations and the individuals as it reduces the burden of safety and security of their data, in addition to minimizing the investment for infrastructure. Every cloud service provider offers not only the storage service but it also extends to preserve the data privacy and security. The inherent mechanism that many cloud service providers implement is n-backup by which the client is guaranteed for data recovery in the case when the original copy of data is damaged or lost. However, for each of the backup copy, it is evident that more storage space is required. In this digital big data era, industry is experiencing the data explosion hence more space and infrastructure would become a necessary need for the service providers. In this paper, a study is conducted on various cloud storage mechanisms, challenges and identified the gaps. Finally, possible solutions are mentioned which is a need for the present cloud storage scenario.
