In this paper, we present a privacy control mechanism called PDE (Privacy Data Envelope) allowing users to protect their privacy sensitive content travelling over social and communication networks. Our solution is based on privacy policies expressed by the user and associated with his content. This approach makes use of a decentralized architecture carried(More)
Complying with security and privacy requirements of appliances such as mobile handsets, personal computers, servers for customers, enterprises and governments is mandatory to prevent from theft of sensitive data and to preserve their integrity.

This demonstration illustrates the concept of Privacy Data Envelopes (PDE) where each piece of information identified by the user as privacy-sensitive is embodied (or "enveloped") into a data structure that in addition to the initial raw data carries privacy-related properties and policies. We show a scenario where such envelopes cross the boundaries of(More)
