Smart, Secure and Sustainable Home: A Socio-Technological Perspective

This paper explores the integration of information technology into homes, focusing on the social aspects of smart, secure, and sustainable living. It presents a proposed approach that includes the use of ontology, policy, and mediator concepts to address privacy, security, and sustainable interaction. The proof of concept includes the Protune framework, which features a trust management language, declarative metalanguage, negotiation procedure, and ontology-based techniques.

  3. Outline • Introduction • Problem Description • Proposed Approach • Proof of Concept • Conclusion

  4. Introduction • Introduction of Information Technology in the house. • Smart • Secure? • Sustainable?

  5. Problem Description • Home as a Social Place • Not well studied • Technical Constraints and Opportunities • House dynamic social place • Burden of access control decisions • Non-intrusive interaction

  6. Grounding Scenario • Joanne is 75 and lives by herself. • Accident. • Establishing communication with daughter Helen fails. • Contact EMTs and provide relevant information. • EMT use provided information to provide prompt help upon arrival.

  7. Proposed Approach

  8. Ontology • Need to model social context • Location • Identity • Time • Activity • Need to ground privacy & security in social context

  9. Policy • A policy is a collection of relational statement or rules about concepts defined in the ontology. • Example: • In case of emergency, contact family member. If contact is not established, escalate by contacting emergency medical services. • Disclose medical records only to trusted medical providers. • Supports sustainable interaction between individuals, while maintaining security and privacy

  10. Mediator • Model interactions as negotiations • Burden of sustainable interaction (conflicts)

  11. Proof of Concept • Protégé, OWL-DL, SUMO • The Protune framework features: • a trust management language supporting (possibly user-defined) actions • an extensible declarative metalanguage for driving decisions about information disclosure • a parameterized negotiation procedure, that gives a semantics to the metalanguage and provably satisfies some desirable properties for all possible metapolicies • general ontology-based techniques for smoothly integrating language extensions • advanced policy explanations in order to answer why, why-not, how-to, and what-if queries

  12. Ontology

  13. Conclusion • Technological developments bring ubiquitous computing into the home. • Complex social structures may hinder deployment of technology. • We hope to fully implement and deploy our framework within the lumenHAUS, to further gain insight.
