M.C. McGrath gave a talk at re:publica 2015 about how metadata from secret surveillance programs and their operators that are published online can be used to monitor the monitors in a sousveillance approach. The talk discusses how the same entities conducting secret surveillance also provide open data about their work, and this data could potentially be utilized to create oversight of surveillance programs in a tactic called "watching the watchers". The transparency toolkit website is also summarized as providing tools to analyze surveillance and human rights issues using open data and free software.

Secret surveillance programs have metadata too. The same people and companies that operate secret surveillance
programs also publish details about their work on the open internet. We can use this data to watch the watchers.
