Police investigation remains open. The photo of one of the minors included a fly; that is the logo of Clothoff, the application that is presumably being used to create the images, which promotes its services with the slogan: “Undress anybody with our free service!”
Thats why we need Blockchain Technology…
Check Blockchain Camera for example: https://github.com/sv1sjp/Blockchain_Camera
Abstract:
Blockchain Camera provides an easy and safe way to capture and guarantee the existence of videos reducing the impact of modified videos as it can preserve the integrity and validity of videos using Blockchain Technology. Blockchain Camera sends to Ethereum Network the hash of each video and the time the video has been recorded in order to be able validate that a video is genuine and hasn't been modified using a Blockchain Camera Validation Tool.How exactly does that prevent someone from uploading a fake video?
The point is to know the time that a video has been uploaded as well as the previous and next videos from it for uses as security cameras, accidents in cars etc to be able to trust a video. (More information can be found on paper).
It won’t, you’ll just be able to verify a source
Not even that. It only allows you to verify that the source is identical to (the potentially wrong information) that was claimed at the time of recording by the person adding that information to the block chain. Blockchain, as usual, adds nothing here.
it can add trust. If there’s a trusted central authority where these hashes can be stored then there’s no need for a blockchain. However, if there isn’t, then a blockchain could be used instead, as long as it’s big and established enough that everybody can agree that the data stored on it cannot be manipulated
but false, nonconsensual nudes are not collectible items that need to have their authenticity proven. they are there to destroy peoples’ lives. even if 99% of people seeing your nude believe you it’s not authnetic, it still affects you heavily
of course not, but that’s not what this comment thread is about. It’s about this:
that’s where it can be very useful to store a fingerprint of a file in a trusted database, regardless of where that database gets its trust from
sure, but again: why woudl anyone like to do that with consensual or nonconsensual nudes?
that is not what this comment thread is about
It proves that the video could not have been created at a later time.
yeah but the problem is mere existance of tools allowing pornographic forgery, not verifying whether the material is real or not
How is that better than an immutable database where you guarantee trust simply by gettin your own public hash receipt for the database every time you introduce a new item? Why obfuscate things by riding the “Blockchain” hype bandwagon?
Who manages and guarantees that immutable database?
A nonprofit with multiple synchronized copies of the database and you can get your own copy, synchronize, fork it if you have the space, like a GitLab repository. Remember this is not for secure transactions and to prevent double-spending like a currency. It’s just an additive database. You don’t need to overkill with a blockchain.
Can you name a nonprofit you’d trust to manage court admissable evidence? How do you resolve differences that can pop up when forks don’t agree?
Look, Git exists and image or document registration in an official onine database is Git diffs with less functionality because you can’t remove previous commits: you just append new lines. This is a solved problem. If you’re trying to solve a double-spend problem, then you need more than that, but it’s overkill for your problem.
PS: maybe I’m oversimplifying it, but here’s more discussion on this:
https://stackoverflow.com/questions/46192377/why-is-git-not-considered-a-block-chain
https://stackoverflow.com/questions/59509764/is-git-distributed-or-decentralized
I know it’s frowned on to modify the history of a remote branch, and I haven’t done much research on it because of that, however I’m fairly certain you can modify the history.
So…who hosts the gitlab/GitHub server that you’d trust to never manipulate the git history?
You still haven’t answered my question of which nonprofit you’d think everyone would agree with should host such a service.
There are examples like DNS or the Mozilla foundation or all sorts of repos. Due to the receipt system you can verify if the commit history has been tampered with (your image has been removed from the database or edited). For court documents each court could host its own database where checksums are verified periodically, by “oracles”.
Are you suggesting that these folks be in charge of maintaining the database? Seems like a very techbro solution. I personally wouldn’t trust them to be responsible for all court admissable evidence because that’s nowhere near their wheelhouse, but I do know of their positive track record. Good luck convincing the layperson to trust them.
What do you mean? What receipt system? Afaik that’s not a gitlab feature.
And who would these oracles be, and how do you resolve differences?
I don’t want to only ask questions, without contributing to the discussion myself, so I’ll say the following.
I suspect your answer to how to resolve differences would be that the majority of databases that agree would be considered the “truth”. How very… block chain.
And as far as finding a solution that everyone would trust, what if it were truly decentralized, across citizens or even the world, like… a block chain. No one organization would be in a position to edit anything.
I’m not saying it’s the only solution, far from it. I’m just saying that while things like NFTs for art are dumb, there actually are a few applications where the features of a block chain actually fit quite well, and keeping of immutable, objective public records definitely strikes me as one of them.
