Abstract: Public Clouds offer a convenient way for storing and sharing large amounts of medical data. Nevertheless, using a shared infrastructure raises significant security and privacy concerns. Even if the data are encrypted, the data owner should share some information with the Cloud provider, in order to enable the latter to perform access control; given the high sensitivity of medical data, even such limited information may jeopardize enduser privacy. In this paper we employ an access control delegation scheme to enable the users themselves to perform access control on their data, which are stored in a public Cloud. To selectively provide access to these data without sacrificing their confidentiality we rely on encryption: our system encrypts data before storing them in the Cloud and applies proxy re-encryption so as to encrypt data separately for each (authorized) user.
