The problem...
Verifying eye witness videos
Rick Turner
News outlets don't have a quick way to verify the eye-witness videos they receive.
But the footage is just
too juicynot to air and share
This leads to a lot of footagewhich is labelled 'unconfirmed'but gets broadcast anyway...
An example:
'Hamas using childrenas human shields'
It has more than 100,000 viewsIt was widely shared on social mediaIt was shown by national news outlets
But it wasn't reliable.The footage was shot in SyriaIt was shot it February
How can we use
technologyto fix the issue?
crowdsourcecredibility
'Shazam'the scene
Here's thetechnical bit...
There are two typesof data in a video:media & meta-data
meta-data
meta-dataGPS informationmdtacom.apple.quicktime.location.ISO6709
meta-dataChronological informationmdtacom.apple.quicktime.creationdate
meta-dataDevice informationmdtacom.apple.quicktime.model
(An iPhone in these examples)
media
media SoundThe audio recorded
mediaVideoThe frames recorded
So we comparethe meta-dataacross the sources(there has to be more than one source for this to work)
And matchor 'shazam'the audio & video
Similarities in the audio and video of multiple videos are found automatically, and the videos are synced automatically.
...so if key points in the video & audio analysis match up...
...and all themeta-datamatches too
...then the videosmust verifyeach other
Some other(less depressing)possible uses
Twitter!** follow @Rick_Turner �
What if we could takeall of those thousands oftweeted photosfrom a sporting event
work outwhere they were takenusing the same technique
And take a virtual tour of
le tour
on a virtual mapwith the same pixel and geolocation matching tech
The possibilitiesare huge!
