	abstract     = {In this paper we present Tamias, a new distributed storage system. Tamias has identity and privacy at its core and builds upon it to bring fine-grained sharing features, delegation and revocation. It is can be used upon any lowlevel distributed storage that has full encryption outside the client. An identity is defined by a public-key that is circulated by the user among other users to introduce himself. In such a situation, introduction is an important step, and out-of-band is always going to be the safest bet. However, we also defined several optional in-band introduction mechanisms. Users can publish information about themselves, solicit other users with a self-introduction, and recommend users they trust to a third party. Finally, using public-key cryptography mechanisms, they can establish secure communication channels that allow to share objects safely within the Tamias storage system. Such a storage is a key piece of technology required by anyone who is privacy conscious, wants to make private online backups, or who is generally worried about Cloud-like online systems taking away their personal data.},
