Abstract

In the digital age where Human Computer Interaction is creating large and entirely unique digital footprints, online accounts and activities can prove to be a valuable source of information that may contribute to verification that an asserted identity is genuine. Online social contextual data – or ‘Digital identities’ -- pertaining to real people are built over time and bolstered by associated accounts, relationships and attributes. This data is difficult to fake and therefore may have the capacity to provide proof of a ‘real’ identity. This paper outlines the design and initial development of a solution that utilizes data sourced from an individual’s digital footprint to assess the likelihood that it pertains to a ‘real’ identity. This is achieved through application of machine learning and Bayesian probabilistic modelling techniques.

Highlights

  • As individuals spend increasing amounts of time interacting online, the line between their physical lives and their digital lives is becoming increasingly blurred

  • Digital footprints map and record the activities that substantiate each individual’s online life. This automated trail logs the habits, interests, events, relationships and communications that are intertwined with an individual’s physical life. It combines this information with metadata to produce an entirely unique blend of information that has the capacity to prove that you possess a true identity

  • The digital age has witnessed a significant rise in identity theft, where perpetrators use the identities of others to essentially violate the law (Spalevic,& Ilic, 2017)

Summary

Introduction

As individuals spend increasing amounts of time interacting online, the line between their physical lives and their digital lives is becoming increasingly blurred. Digital footprints map and record the activities that substantiate each individual’s online life This automated trail logs the habits, interests, events, relationships and communications that are intertwined with an individual’s physical life. It combines this information with metadata to produce an entirely unique blend of information that has the capacity to prove that you possess a true identity. The digital age has witnessed a significant rise in identity theft, where perpetrators use the identities of others to essentially violate the law (Spalevic,& Ilic, 2017) This is an important issue, as fake identities present terrorists and criminals with the opportunity to commit various types of crime, while concealing their true identities (Kean, et al, 2004).
