An Accountability Scheme for Cloud Storage Leakage

Abstract

With the rapid development of information technology, the privacy and security of cloud data is the problem that the cloud users are facing, when cloud data is leaked, the responsibility is hard to judge, it is easy for cloud storage server to shift responsibility away. The article proposes an accountability scheme, which is to store the information of cloud storage server on the data and then encrypt it multiple times. It is a great way to determine the responsibility of cloud storage server for data leakage. At the same time, the scheme can realize the integrity verification of cloud data.
