Mini project centers in chennai , 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 unilaterally makes access control decisions( embedded project centers in chennai ). Existing clouds are, thus, agnostic to the notion of shared ownership. This can be significant limitation in much collaboration because, for example, one owner can delete files and revoke access without consulting the other collaborators. In this paper, we first formally define a notion of shared ownership within a file access control model( arduino project centers in chennai ). We then propose two possible instantiations of our proposed shared ownership model. Our first solution, called Commune, relies on secure file dispersal and collusion resistant secret sharing to ensure that all access grants in the cloud require the support of an agreed threshold of owners( embedded project centers in chennai ). As such, Commune...
