    This is a great idea, but there should be two things made sure:

    – Obfuscation of the app itself, because investigators may get warned if they find this app on a users device.
    – Security for the sender. There should be no way to forward the image with the full metadata unencrypted, as this would be dangerous for the photographer. In the hurry of a editorial office a copy may be published online with all data. There could be a second app which shows both data, but will not export them together.

      Thank you for the feedback, Werner. Those are both excellent points. We are generally working on App Obfuscation for all of the apps we developed, and that will extend to InformaCam. As for the second point, there is currently no point where we create a version of the photo or video with the unencrypted data in it. We have a tool for analysis and visualization of the data once it is extracted, but from that point, it has only been received by a trusted party.

    “signs each bundle of data with the user’s public key.”

    This should read “private key”. The public key is – as the name implies – available to everyone, so that would not work as an authentication of the original source.

      Ah, yes Kai. Thanks for finding the mental typo. Will fix it!

    Great idea! One thing to keep in mind: It is not particularly difficult for criminals or secret services to falsify location-data (on Android you can even enable fake positions in the developer options, which you can detect in your App though). If a device has been modified with a custom rom (or is connected to a modified bluetooth gps) it is almost impossible to detect if the location is correct or not. Have you thought about aggregating data from different persons in the same location in order to check the trustworthiness of the footage?

      We are actually partnering with a project at UC Berkeley called Rashoman, which is working on visualization of aggregated media: http://automation.berkeley.edu/rashomon/

      We are also definitely aware of the many ways you can fake input data into an Android device, and are working to defend against them. We appreciate you highlighting a few of these here!

    Is there an expected release date for this?

    Can’t say enough good things about InformaCam, and the other privacy products at The Guardian Project. Thank you for your efforts and look forward to seeing what App comes next. Keep up the good work!! Darren Chaker
