Cloud Data Leakage, Security, Privacy Issues and Challenges: Review.

Cloud Computing services are widely expanded all over the world because of it comfort and reliable services offered to the user on demand. The majority of the users who are using different pervasive devices are directly or indirectly dependent on the cloud services. The consumer data stored at vendor end has lot of security concerns. However, cloud vendors offer many cloud-computing mechanisms explore the data leakages are challenging issues to be addressed in various levels. This paper presents the systematic investigation of data leakages, which occur in cloud services. In our study we present systematic analysis of (i) data leakages in cloud environment, (ii) security issues related to cloud environment, (iii) cloud security mechanisms and finally we present the challenges in cloud security that need proper solutions [ABSTRACT FROM AUTHOR]
