This paper introduces the concept of Secure Spaces, one step ahead of Smart Spaces, on information security. We define Secure Spaces as physically isolated environments in which any resource is completely protected from its unauthorized objects with respect to information security. In other words, only if inside them, any information resource is completely protected from being accessed by its unauthorized visitors, and any visitor is completely protected from being exposed to her unwanted information resources. To build such a secure Smart Space, we propose a formalized model and architecture for space entry control based on its dynamically changing contents such as its visitors, physical information resources, and virtual information resources via its embedded output devices.
