In this paper we report our study involving an early prototype of TAPESTRY, a service to support people and businesses to connect safely online through the use of a Machine Learning generated visualization. Establishing the veracity of the person or business behind a pseudonomized identity, online, is a challenge for many people. In the burgeoning digital economy, finding ways to support good decision-making in potentially risky online exchanges is of vital importance. In this paper, we propose a Machine Learning method to extract temporal patterns from data on individuals’ behavioural norms in their online activity. This monitors and communicates the coherence of these activities to others, especially those who are about to disclose personal information to the individual, in a visualization. We report findings from a user trial that examined how people accessed and interpreted the TAPESTRY visualization to inform their decisions on who to back in a mock crowdfunding campaign to evaluate its efficacy. The study proved the protocol of the Machine Learning method and qualitative insights are informing iterations of the visualization design to enhance user experience and support understanding.
