Towards Shared Ownership in the Cloud

Abstract

Cloud storage platforms promise a convenient way for users to share files and engage in collaborations, yet they require all files to have a single owner who makes unilateral access control decisions. Therefore, Project on Towards Shared Ownership in the Cloud existing clouds are agnostic of the notion of shared ownership. In a lot of collaboration this can be a significant limitation because, for example, one owner can delete files and revoke access without consulting the other collaborators.

We then propose Project on Towards Shared Ownership in the Cloud two possible instantiations of our proposed model of shared ownership. Our first solution, called Commune, relies on secure file dispersal and collusion-resistant secret sharing to ensure that all cloud access grants require the support of an agreed owners threshold.

Conclusion

Even though existing cloud platforms are used as shared repositories, they do not support any notion of shared ownership. We consider this a severe limitation as contributing parties can not jointly decide how their resources are used. We introduced a novel concept of shared ownership in this paper and described it through a formal model of access control, called SOM. Then we propose two possible instantiations of our proposed model of shared ownership.
