Abstract:
Affordable access to large online hard disks via the Internet has emerged by the continuous evolving of public and private storage clouds. However, difficulties arise as soon as users of such storages want to employ services from different cloud providers simultaneously, e.g., for collaboration among institutions that use different storage providers or for distribution of data backups. The reasons for this are dissimilar user accounts and incompatible access methods. This contribution describes a solution to that problem that does not need additional middleware to achieve the goal of unified authentication, authorization (AA) and access except WebDAV, which is an open standard. Our method is based upon a dynamic localization of the user by means of a world-wide unique user name. The solution is thus suitable for implementing federations of storage clouds in which multiple organizations can jointly provide a unified access to file systems that are distributed across the Internet.
