Data Integrity on Remote Storage for On-line Co-working

Nowadays, the cloud computing have engulfed not only the IT industry but also the general publics all around the world. Our daily life is now full of various cloud services such as Gmail or Google Document. Although the cloud services can provide on-line platforms for co-working between a group of collaborators, trust is always a hesitation for a user to adopt cloud services. In this paper, we aim at the integrity issue for on-line co-working and seek for a proper solution. We develop a framework to enable the remote data integrity verification for on-line co-working scenarios. In addition to provide a framework, we also show the feasibility of our framework by providing a concrete example.
