Oruta Privacy-Preserving Public Auditing for Shared Data in the Cloud

Oruta: Privacy-Preserving Public Auditing for Shared Data in the Cloud With cloud storage services, it is commonplace for data to be not only stored in the cloud, but alsoshared across multiple users. However, public auditing for such shared data – while preserving identityprivacy – remains to be an open challenge. In this paper, we propose the first privacy-preservingmechanism that allows public auditing on shared data stored in the cloud. In particular, we exploit ring signatures to compute the […]
