Just been watching the latest in the “Rebel Geeks” series on Al Jazeera. Today the episode was called “A Bigger Brother” <http://www.aljazeera.com/programmes/rebelgeeks/2015/12/bigger-brother-151216102151145.html>, centred around the use of an open-source Android app called CameraV. The aim of this app is to record video along with a whole heap of corroborating metadata (GPS coordinates, local wi-fi networks etc) to make the footage credible enough, in particular proof enough against accusations of tampering, to be used as evidence in court. This is particularly important where the video is documenting crimes committed by people in positions of power and trust, such as the police. They used a nice term for this: “sousveillance” (watching done by ordinary people from below), as compared to the more usual “surveillance” (watching by those in privileged positions from above). One interesting comment made in the program was that the phone needs to look like it is not capturing video while the app is running, because in a place like Rio De Janeiro, the cops will grab phones away from people who they think are filming them. I did some digging around on GitHub, and found that this app is part of the Guardian Project, and they have a whole bunch of other useful-looking tools related to encryption, privacy and so on <https://github.com/guardianproject> They also have a website <https://guardianproject.info/>.
