Comment on Anon predicts the future
alekwithak@lemmy.world 4 days agoI like webghost0101’s Idea:
[…] a blockchain linked video camera where metadata of footage gets written into the chain to combat fake news and misinformation.
The goal would be to create a proof and record of original footage, to which media publishers and people who share can link towards to verify authenticity/author.
If the media later gets manipulated or reframed you would be able to verify this by comparing it to the original record.

blockchain is a totally useless extra bit glued on there. All the real evidence will be the cryptographic signatures added by the hardware manufacturer (which can be faked, but requires extracting the keys from the “security chip” in the camera which may be very difficult)

Yeah, the interface between the analog reality and its digital representation will always be the weak point. But, such a scheme could at least mean that whatever reality is going to be represented at least needs to be decided relatively quickly after the moment has passed, rather than it being possible to create whatever video helps the most well after the fact.
Like if someone is trying to frame someone of some crime, with video authentication, they need to create and authenticate a video based on when they want the supposed crime to occur. Without it, they could find out when their target has alibi gaps and just target that time after the fact.
Though another bit on reality’s side is corroborating with other nearby cameras. If my camera says you walked onto my property at 8:00 and left at 8:30, there should be nearby cameras I don’t own that pick you up before and after those times. Every camera that has an angle should pick it up. Though advantage goes to those with many cameras, since real footage or fake, they’d be better able to create a longer narrative and dispute conflicting narratives.
