This is multi-layered problem with no simple answers but many comments here touch on solutions, note there will not be 1 solution. Here are a couple of concepts I know are being worked on
- Secure Data at the Source -
Public Created - I have seen some demo's of phone apps that put video and pictures from phone directly on the blockchain with gps, time stamps etc.. Also have heard of dongles being added to phones
Professionally Created at Device - have read about hardware getting processors to secure data directly on the blockchain at the device.
Created at Editing Software - This could be connected to the identity of the original on the blockchain and then the edited version has notes with it and added to the blockchain as an edited version of the first.
Security cameras for Customs and Border Patrol are getting blockchain capabilities added per this quote - " Factom (blockchain) has integrated their technology into two brands of cameras used by CBP at border locations to ensure data collected from these cameras is tamper proof" - http://www.activecyber.net/dhs-st-lays-out-a-broad-yet-innov...
IoT Devices - This micro processor can be added to an IoT (raspberry pi and the like) device and secure data the source - https://iot-sas.tech/
Professionals (media) and citizens can then have proof of what and when they created the video and potential a certification can be added in manor and tool for others to check the video is in fact the original.
None of the above completely solves the issue but with implementing these and having standards the public can start to trust what they are watching is authentic.
A friend actually built it but from my understanding, it is built for when IoT devices needed to share data outside their internal business. For example, an IoT device in a container gets moved from a warehouse to a 3rd party trucking company. The trucking has an IOT device and the two devices transmit data between them and some get sent back to a database. I may not be doing this justice.
The DOE is funding potential solutions, saw this earlier this week
