TAPESTRY: A De-Centralized Service for Trusted Interaction Online

Abstract

We present a novel de-centralised 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.

Revealing Cumulative Risks in Online Personal Information: A Data Narrative Study

“…More seriously, perpetrators of intimate partner violence may go to great lengths online to track down their victims (survivors) through their digital traces across multiple platforms, in order to continue their abusive behavior [35]. Examples of tools developed to harvest digital traces include a Blockchain-based application that enabled people to establish others' trustworthiness [82], and a tool that combined online dating site posts with fitness tracker information to reveal where people lived, whether they lived alone, and when they were at home or out exercising -information that was subsequently exploited by stalkers [20]. Using Facebook profiles, Bachrach et al [8] were able to infer people's Big Five Personality traits.…”

Blockchain and Beyond: Understanding Blockchains Through Prototypes and Public Engagement

“…HCI and particularly design-led researchers have also sought to understand the opportunities and implications of blockchain technologies in speciic domains, such as: education [123], charity and philanthropy [44,45,102], identity management [23,34,35,154], supply chains and transport [51,77,78,115,136], shared commons and civic participation [25,39,96].…”

Building A blockchain-based decentralized digital asset management system for commercial aircraft leasing

“…Data curation in general (Heiss et al, 2019), and particularly in the case of legal compliance and liability (Arribas et al, 2020) demands the inclusion of off-chain actors and/or agents. Therefore, the reliability and trustworthiness of these actors should be further analyzed (Yang et al, 2020).…”
