Abstract
This paper introduces guaranteed data lifetime, a novel system property ensuring
that sensitive data cannot be retrieved from a system beyond a specified time. The
trivial way to achieve this is to "reboot"; however, this is disruptive from the
user's perspective, and may not even eliminate disk copies. We discuss an alternate
approach based on state re-incarnation where data expiry is completely transparent
to the user, and can be used even if the system is not designed a priori to provide
the property.
