A Secure Data Distribution and JAR Authentication in Cloud Storage Systems

Cloud computing enables highly scalable services to be easily consumed over the Internet on an as-needed basis. A major feature of the cloud services is that users’ data are usually processed remotely in unknown machines that users do not own or operate. While enjoying the convenience brought by this new emerging technology, users’ fears of losing control of their own data (particularly, financial and health data) can become a significant barrier to the wide adoption of cloud services. To address this problem, we propose a Decentralized information accountability framework. We propose a logging mechanism along with user’s data and policies. Whenever a user logs into the system, then a log record will be generated and those log records will be stored in a JAR (Java Archives) file. We propose a single JAR which has two functionalities like matching policies and providing/decrypting the file if that policy is matched. One more approach we are providing ABE technique which creates attributes and ensures security for user’s related information. In addition to this we proposed a JAR signer tool used for signing and verification of JAR file. We provide extensive experimental studies that demonstrate the efficiency and effectiveness and the proposed approaches.
