I’m using a blockchain because it’s currently the most practical Byzantine Fault Tolerant (BFT) network available for timestamping the Initialization Vector and final hash. If you …

Largely true, although submitting timestamp hashes to the blockchain is probably the easiest bit. "Camera looking at a monitor": While that might be simpler in some setups, it does…

Thank you! It is indeed a little like a signature based on proof-of-projection. As they say, once you have a signature, you have a most of a cryptosystem. I've been experimenting w…

I've developed a novel approach to creating tamper-evident video via cryptographic feedback loops between projectors and cameras. The process works as follows: 1. A projector displ…

A real solution is to create privacy-preserving proofs regarding the state of a timestamped cryptographic feedback loop in projector-camera systems. It's trivial to add incoming im…

In my opinion, yes. I posted elsewhere on this thread to spam my project, which is to derive an initialisation vector from a blockchain (or other interlocutor), derive a projection…

A sample dataset is downloadable at truthbeam.eth over IPFS. In its basic form the Truth Beam mechanism comprises a video projector and global shutter camera with an exposure time …
