Secure Sharing Of Related Organization Records in Cloud Computing

Cloud computing has emerged as one of the most influential paradigms in the IT industry in recent years. Since this new computing technology requires users to entrust their valuable data to cloud providers, there have been increasing security and privacy concerns on outsourced data. Several schemes employing attribute-based encryption (ABE) have been proposed for access control of outsourced data in cloud computing. The proposed scheme is not only achieves scalability due to its hierarchical structure, also inherits flexibility and fine-grained access control in supporting compound attributes of ASBE. This method is used to access the single dataset or local dataset from the cloud computer. In proposed system, data interoperation systems integrate information from different local sources to enable communication and exchange of data between them. A common model for these systems involves a global representation of the local data, which acts as a mediator for translating queries and conveying data to and from these sources using the global-as view approach. In addition, global resource employs multiple value assignments for access expiration time to deal with user revocation more efficiently than existing schemes. It formally proves the security of global resource based on security of the ciphertextpolicy attribute-based encryption (CP-ABE) scheme and analyzes its performance and computational complexity.
