Ability-based expression control for secure spaces

Abstract

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, we might unexpectedly enter the public spaces that have our unauthorized contents and/or unwanted characteristics, i.e., they are not always secure and safe. To solve this problem, my previous work has introduced the 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 not only spatial entry control but also Ability-Based Expression Control according to how preferentially a virtual information resource should be outputted in a Secure Space where shared by visitors with perceptibility and understandability of the virtual information resource's content and expression.
