This open-source Android app helps protect the identity of subjects in human rights videos. ObscuraCam detects faces automatically (you can select any it misses) and then offers various options to obscure them, including blurring with pixels and erasing completely. The app also deletes metadata such as location and camera type. These features grew out of a conference session on mobile tools and human rights and a subsequent hack day that outlined early features.
