If you know the MD5 hash of 60 minute movie and you have the clip of it between 5th and 6th minute...how long would it take with current computing power to generate full movie from that knowledge?
You couldn't. One minute of movie and a single MD5 hash aren't enough to reproduce an entire movie, because movies don't all have distinct hashes.
you missed my point here.
Basically what i meant was to keep generating MD5 hashes until an file has been generated which has identical "video data" between 5th and 6th minute.
Given that you would get same MD5 hash from the 5th and 6th minute of generated video aswell as the MD5 hash for the original 5th and 6th minute was.
Thus "reverse" hashing the whole movie from only 1 minute of data.
Sure it wouldn't be efficent in any possible way...but is there any "probability" math that could be done on that subject?
In MY theory you could store movies just by storing their MD5 hash and 5 seconds of footage...given that you have near-unlimited computing power.
But i might be missing an important point somewhere that totally wrecks this theory, and that's also why i made this topic.
