TAPESTRY:A Blockchain based Service for Trusted Interaction Online
We present a novel blockchain based service for proving the provenance of
online digital identity, exposed as an assistive tool to help non-expert users
make better decisions about whom to trust online. Our service harnesses the
digital personhood (DP); the longitudinal and multi-modal signals created
through users' lifelong digital interactions, as a basis for evidencing the
provenance of identity. We describe how users may exchange trust evidence
derived from their DP, in a granular and privacy-preserving manner, with other
users in order to demonstrate coherence and longevity in their behaviour
online. This is enabled through a novel secure infrastructure combining hybrid
on- and off-chain storage combined with deep learning for DP analytics and
visualization. We show how our tools enable users to make more effective
decisions on whether to trust unknown third parties online, and also to spot
behavioural deviations in their own social media footprints indicative of
account hijacking.Comment: Submitted to IEEE TSC Special Issue on Blockchain Services, May 201
