TightLip: Keeping Applications from Spilling the Beans

TightLip: Keeping Applications from Spilling the Beans (presented with demo)

Managing the permissions of any shared space is challenging, even for highly skilled computer users. This task is particularly daunting for untrained PC users, for whom access control errors are routine and can lead to damaging privacy leaks. A 2003 usability study of the Kazaa peer-to-peer file-sharing network found that many users share their entire hard drive with the rest of the Internet, i...

Clustering and Information Sharing in an Ecology of Cooperating Agents or How to Gossip without Spilling the Beans

Many future applications for advanced software agents imply distributed computation involving sensitive or private data. Most efforts to date have assumed that privacy may be traded away in order to distribute the computation, or assume that the only viable choices for users are to entrust their data completely to a third party, or not at all. This research, still very much in progress, is inte...

Reaching Your Goals without Spilling the Beans: Boolean Secrecy Games

Inspired by the work on Boolean games, we present turnbased games where each of the players controls a set of atomic variables and each player wants to achieve some individual goal in such a way that the other players remain unaware of the goal until it is actually achieved. We present definitions of winning such games with hidden goals for different non-cooperative settings, and discuss in whi...

Frappé: Functional Reactive Programming in Java

Functional Reactive Programming (FRP) is a declarative programming model for constructing interactive applications based on a continuous model of time. FRP programs are described in terms of behaviors (continuous, timevarying, reactive values), and events (conditions that occur at discrete points in time). This paper presents Frappé, an implementation of FRP in the Java progamming language. The...
