 Another fundamental question is whether, given the future (and even current) level of informational connectivity, it is feasible to protect privacy by trying to hide information from parties who may use it in undesirable ways. Gutwirth &amp; De Hert (2008) argue that it may be more feasible to protect privacy by transparency – by requiring actors to justify decisions made about individuals, thus insisting that decisions are not based on illegitimate information. This approach comes with its own problems, as it might be hard to prove that the wrong information was used for a decision. Still, it may well happen that citizens, in turn, start data collection on those who collect data about them, e.g. governments. Such “counter(sur)veillance” may be used to gather information about the use of information, thereby improving accountability (Gürses et al. 2016). The open source movement may also contribute to transparency of data processing. In this context, transparency can be seen as a pro-ethical condition contributing to privacy (Turilli &amp; Floridi 2009).
