Of the fakes: Some NGO:s are vetting film material to tag specific ones as credible evidence of e.g. states behaving badly. They compare time of day to known weather patterns, cross reference previous film to see if something has been reused etc.

- mirimir 9y agoThat's a good idea, for sure. But all that stuff can be faked too. And the most resourceful players will have the best fakes.
- zimpenfish 9y agoI don't even think you need "the best fakes" these days - just have your press secretary flat out deny that something happened. If any reporters push back, stop asking them questions and/or block them from your briefings. Works for a fair few countries.
- TeMPOraL 9y agoA possible solution to some of the problems would be creating (and for official videos, requiring) a chain of trust, enforced by strong crypto, starting at the original recording device and ending at the viewer's display. Some trusted parties would also probably have to vouch for the start of the chain, too. That basically sounds like the dream world of DRM people, though.
- mirimir 9y agoDRM I don't like. But authentication to reporter, recording device, etc would certainly be useful. Plus proof of integrity. Maybe also cross-linking chains of trust with nearby devices. So devices corroborate each other.
- throwaway2048 9y agoThe people in a position of power are already in the best position possible to abuse a root of trust like that. Look at the TLS x509 PKI, its a total complete mess. This is not a workable solution.
- honestoHeminway 9y agoTrying to sell decentralized systems to people who are afraid to loose control, are we?
- Udik 9y agoWhat would definitely work is a blockchain. It would definitely make sense at least for reliably timestamping video recordings.
- eru 9y agoOnly if you also publish your video (or a hash of it) at the same time.
- beagle3 9y agoThere's an analog hole here ... what's to stop me using a trusted camera/chain/everything to take picture of an 8K screen with a fake image? (Canon had a "trusted" model as such. It was broken, IIRC by elcomsoft, shortly after release).
- wffurr 9y agoOr a Potemkin village.
- allendoerfer 9y agoA camera that shoots 360°, saves coordinates and date, would make it harder.
- beagle3 9y agoHow could it tell coordinates in either space or time? non-military-grade GPS is spoofable (not really easy yet, but easier by the day) and GPS signal is rarely available inside a building (and sometimes just under an awning or cloudy days, or near skyscrapers - GPS in NYC is horrible; mobile phone GPS are as reliable as they are because they take cell towers and wifi into account). The important point is " making it harder " - but how hard is hard enough depends on the party in question, and for many important ones, the simple answer is "not hard enough".
- eru 9y agoWidespread high quality evidence will make the fakes costlier to produce. Even resourceful players have ultimately limited resources. http://tvtropes.org/pmwiki/pmwiki.php/Main/DystopiaIsHard http://tvtropes.org/pmwiki/pmwiki.php/Main/DystopiaIsHard
