Research On Multi-User Data Sharing Service Based On Object Storage

Existing Object Storage providers generally use signature as data file access credential, and AWS Signature method is widely recognized as a standard security notion. However, most of the Object Storage service suffer from the disadvantages of weak data sharing security, which has severely impeded the daily usages of cloud storage users. In this paper, we propose a new framework, which called Multi-user Data Sharing Scheme (MDSS), bases on Object Storage for the security of sensitive personal data in data sharing. For the sake of data security, permission authentication algorithm is added to AWS Signature method. In addition, this scheme can solve the problem of real-time synchronization of multi-machines data and fine-grained data sharing strategy creation.
