Immutable Views -- Access control (to your information) for masses

There are a lot of on going efforts in the research community as well as industry around providing privacy-preserving and secure storage for personal data. Although, over time it has adopted many tag lines such as Personal Information Hub [12], personal container [8], DataBox [4], Personal Data Store (PDS) [3] and many others, these are essentially reincarnations of a simple idea: provide a secure way and place for users to store their information and allow them to provision who has access to that information. In this paper, we would like to discuss a way to facilitate access control mechanism (AC) in the various "personal cloud" proposals.
