ObscuraCam is an Android application that allows you to obscure faces or objects in photos or videos to keep certain information private. It allows you to black out or pixelate certain areas of an image. You can also reverse pixelate, so that only the person is visible and the background becomes blurred. The application also allows you to remove telltale metadata such as GPS location, phone make and model, and author information. It was developed in partnership between human rights video organisation Witness.org and the Guardian Project.
