An Efficient Data Sharing and Retrieval Method for Cloud Computing

Abstract

now a days mobile devices can use cloud for data Access and manipulation without knowing overhead of local data management this may lead to leakage of sensitive data. Major disadvantage is to provide security for the user data , so this leads to concern for the user to access cloud computing. Lot of Research work carried out to provide security to user data over cloud computing, However these solutions are not resolve issues of mobile cloud computing due to constrained resource in mobile devices[2]. To overcome these issues, proposed methodology efficient data sharing and retrieval method, provide secure access control terminology using attribute based encryption in cloud platforms, as well as by using lazy-revocation technique will reduce user revocation cost
