A framework for the lived experience of identity

Abstract

This paper presents a framework for the design of human-centric identity management systems. Whilst many identity systems over the past few years have been labelled as human-centred, we argue that the term has been appropriated by technologists to claim moral superiority of their products, and by system owners who confuse administrative convenience with benefits for users. The framework for human-centred identity presented here identifies a set of design properties that can impact the lived experience of the individuals whose identity is being managed. These properties were identified through an analysis of public response to 15 historic national identity systems. They capture the practical design aspects of an identity system, from structural aspects that affect the flow of information - Control Points, Subject Engagement, Identity Exposure, Population Coverage--to the metrical aspects that considers how information is used and perceived--Expert Interpretation, Population Comprehension, Information Accuracy, Information Stability, Subject Coupling, Information Polymorphism. Any identity system can be described in terms of these fundamental properties, which affect individuals' lived experience, and therefore help to determine the acceptance or rejection of such systems. We first apply each individual property within the context of two national identity systems--the UK DNA Database and the Austrian Citizen Card, and then also demonstrate the applicability of the framework within the contexts of two non-government identity platforms--Facebook and Phorm. Practitioners and researchers would make use of this framework by analysing an identity system in terms of the various properties, and the interactions between these properties within the context of use, thus allowing for the development of the potential impacts that the system has on the lived experience.
