In public spaces, there are a number of different contents such as visitors, physical information resources, and virtual information resources via their embedded output devices. Therefore, the author might unexpectedly enter the public spaces that have our unauthorized contents and/or unwanted characteristics. The author’s previous papers have introduced the novel concept of “Secure Spaces”, physical environments in which any visitor is protected from being pushed her unwanted information resources on and also any information resource is always protected from being accessed by its unauthorized visitors, and the model and architecture for space entry control and information access control based on their dynamically changing contents. Aiming to build more flexible Secure Spaces, this paper proposes an extended model for context-aware query control and search control based on how preferentially a virtual information resource should be outputted in a Secure Space as well as spatial entry control based on whether a virtual information resource should be granted or denied to be outputted in a Secure Space.
