  As people across the world become increasingly aware of how their privacy is
compromised in this digital era, the field of Privacy Enhancing Technologies,
or PETs, has boomed. The first workshop on Privacy Enhancing Technology was in
2000, then called the "Workshop on Design Issues in Anonymity and
Unobservability." By 2007, the workshop had ballooned into a full symposium. In
2015, the first issue of the Proceedings on Privacy Enhancing Technologies
journal was published. This year in 2019, there were 4 volumes of Proceedings
on Privacy Enhancing Technologies published, containing a total of 66 papers.
Of these papers, we identified 14 which specifically describe PETs that have
been newly developed or utilized in a new way. We focused on 3 papers that
seemed to have widespread use cases. Some of these use cases, however, include
criminal activity. While heavily focused on adversarial actions and capability,
much of security research does not focus on or consider the social science and
motivations behind bad actors. We believe that this is a critical factor to
consider when working on the problem of cybercrime. In this paper, we will
analyze some of the cutting edge PETs and the potential risks associated with
them from the lenses of computer science and criminal justice. We argue that
the continued development of privacy enhancing technology contributes to the
global rise of cybercrime.
