ABSTRACT

In recent years use of Cloud computing in different mode like cloud storage, cloud hosting, cloud servers are increased in industries and other organization as per requirements. While considering the power, stability and the security of cloud one can’t ignore different threats to user’s data on cloud storage. Sourcing and untrusted cloud servers, the data access control become a challenging issue in cloud storage systems. Existing access control schemes are no longer applicable to cloud storage systems, because they either produce multiple encrypted copies of the same data or require a fully trusted cloud server. Malicious user at cloud storage is become most difficult attacks to stop. In proposed system we are implementing the concept of multiple cloud storage along with enhanced security using Attribute Based Key Based Policy (ABKBP) encryption techniques where rather storing complete file on single cloud system will split the file in different chunks then encrypt and store it on different cloud and the meta data required for decrypting and rearranging a file will be stored in metadata management server. Because of security issues in cloud computing, many big organizations worldwide enable to use cloud storage services. In this review paper we are aiming to present review of security issues in cloud storage systems, different methods, advantages, challengesetc.
