  When pieces from an individual's personal information available online are
connected over time and across multiple platforms, this more complete digital
trace can give unintended insights into their life and opinions. In a data
narrative interview study with 26 currently employed participants, we examined
risks and harms to individuals and employers when others joined the dots
between their online information. We discuss the themes of visibility and
self-disclosure, unintentional information leakage and digital privacy
literacies constructed from our analysis. We contribute insights not only into
people's difficulties in recalling and conceptualising their digital traces but
of subsequently envisioning how their online information may be combined, or
(re)identified across their traces and address a current gap in research by
showing that awareness is lacking around the potential for personal information
to be correlated by and made coherent to/by others, posing risks to
individuals, employers, and even the state. We touch on inequalities of
privacy, freedom and legitimacy that exist for different groups with regard to
what they make (or feel compelled to make) available online and we contribute
to current methodological work on the use of sketching to support visual sense
making in data narrative interviews. We conclude by discussing the need for
interventions that support personal reflection on the potential visibility of
combined digital traces to spotlight hidden vulnerabilities, and promote more
proactive action about what is shared and not shared online.
