Till now almost all the cloud data which is collected from remote locations is stored in the centralized storage medium, there are a lot of security issues that takes place in the centralized data storage. It is facing with a lot of problems like no proper data authentication and data authorization present in the networks. Hence we try to utilize the new principle known as data de-centralization in which the storage and access permission will lie in the individual departments rather than in the cloud server. In this proposed paper we try to use a third party global identifier in order to verify the key permissions which is granted by the data owner and this will be generating the keys for the data users who try to request the data. In this proposed thesis we try to develop a new scheme by adding a global identifier like Attribute Authority (AA) for providing access keys for the data users who wish to access the sensitive information from the cloud server. In this proposed work we try to construct Composite Order Bilinear Groups scheme for providing access facility for the data users and provide more security for the sensitive data. By conducting various experiments on our proposed model, our result clearly tells that our proposed system is very efficient to access the data in a de-centralized manner by using a global identifier.
