A hot topic in the news this week is new technology that allows someone with the right software to fake a video of a person saying something he didn't say. Experts warn how this technology will not only lead to lots of fake news, but will dilute the trustworthiness of real videos.
The DLT/blockchain can provide a partial solution by authenticating a video or audio (or image) in real time by writing periodic hashes of the data to the ledger, providing a time-stamped verification of the content. Videos with this verification will be more reliable and harder to fake because you can at least confirm the approximate time the recording was created.
Ideally, one would have an instant link to the net to write in real time. One easy use case would be dashboard cams writing ever minute a hash of the video that has been recorded. Another is security cams. Another is software apps that you use when you want to film an encounter with police or a store clerk. One could also embed the ID of the device and other data to further authenticate the recording.
Iota is a very good solution for this because it offers potential rapid transactions, without charge and that can be used by small devices like security cameras and cell phones.
If anyone has any suggestions to improve upon this idea or can see reasons why the dlt-signature-timestamp would not be reliable, please post your thoughts below.
