Abstract
Subscriber (user) data is encrypted and stored in a service provider cloud in a manner such that the service provider is unable to decrypt and, as a consequence, to view, access or copy the data. Only the user knows a user-specific secret (e.g., a password) that is the basis of the encryption. The techniques herein enable the user to share his or her data, privately or publicly, without exposing the user-specific secret with anyone or any entity (such as the service provider).
