Anyone else notice that Dropbox globally indexes files? If you upload a large file already elsewhere on their servers (Linux distro ISO, scene-made TVRip or DVDRip, etc), it "uploads" instantly, and will begin downloading immediately on your other linked Dropbox machines. Makes me wonder how hard it is to download a file by hash (via the Linux client, parts of which are open-source), without having the file, or how e…
The good news for video pirates is: -- Every time a video is encoded, it hashes differently. So a studio could find a torrented file and find people downloaded that exact copy, but they couldn't just ask for every copy of a show. -- If this became a problem, you could toss some random metadata on a file and it would hash differently. Or zip a file/program with a text file containing a guid. Etc.
Really? Even with the exact same source file and exact same codecs/methodology? Why is that, is there an "encoding time" metadata field or something?
