On human-centred security: A new systems model based on modes and mode transitions
Edwin J Beggs, John V Tucker, Victoria Wang
We propose an abstract conceptual framework for analysing complex security systems using a new notion of modes and mode transitions. A mode is an independent component of a system…
Analogue-digital systems and the modular decomposition of physical behaviour
E. J. Beggs, J. V. Tucker
We take a fresh look at analogue-digital systems focussing on their physical behaviour. We model a general analogue-digital system as a physical process controlled by an algorithm…
Analogue-digital systems with modes of physical behaviour
Edwin Beggs, John V. Tucker
Complex environments, processes and systems may exhibit several distinct modes of physical behaviour or operation. Thus, for example, in their design, a set of mathematical models…
Formalising Surveillance and Identity
Victoria Wang, John V. Tucker
Surveillance is a social phenomenon that is general and commonplace, employed by governments, companies and communities. Its ubiquity is due to technologies for gathering and proce…
On the Role of Identity in Surveillance
Victoria Wang, John V. Tucker
Surveillance is a process that observes behaviour, recognises properties and identifies individuals. It has become a commonplace phenomenon in our everyday life. Many surveillance…
