Facebook announced a ban on fake video or audio on Monday. For example, a video claiming that US President Donald Trump declared war against Russia must be a fake video because he has not yet done so.

Facebook said that if the editing of the video is beyond the normal adjustment range, it will delete the video to prevent the video from misleading someone into thinking that someone has said something they did not say. In addition, it will delete the content superimposed on the video through machine learning algorithms designed to look real.

If the video is considered to be fake, Facebook will send it to one of its content reviewers, such as the Associated Press or Agence France-Presse, and employees will review it. "this policy does not apply to content that imitates or satirizes, or videos edited simply to omit or change the order of words," it wrote. "

Maybe Facebook can solve this problem through technical means.

The products of some blockchain companies can solve this problem from the source. Amber Video, for example, can encrypt all data captured using its application and record "fingerprints" on the blockchain in real time, so video can always be traced back to its source.

Amber Video claims that even if the video is spliced into several different clips, the source of the video can be traced. The five-minute news video said: there may be 20 sound clips and 15 B-roll shots. [using Amber Video's software], each of these elements will maintain its fingerprint throughout the release process, "Amber Video CEO Shamir Allibhai said in a November statement.

If the video is tampered with, you can easily mark the video as fake. "you don't have to trust anyone," Allibhai said.

But for now, although Facebook is worse at detecting fake news than algorithms, Facebook insists on using old-fashioned manual censorship.
