I can create a torrent. But how do I insure none of my computer's personal information and identifiers are saved on that file? I dont want me to be found out if someone opens the file and somehow can see I'm the one who created it.

In other hand, how do the pirates create and upload media into torrents while protecting themself from being found out?

Thank you for your answers. I forgot that the computer I use for this purpose is Linux. I was worried with Windows, so use Linux on a spare laptop for this activity. Worry with metadata and those personal identifiers.

I use exiftool for images, but it does not work with MKV. I can try Ffmpeg to see if any metadata comes back. But I worry not just for metadata. But also same for any other parameter that is in the file itself. Metadata is outside, might be other identifiers encoded in the file. The two things are my big worries.

I try hex editor some other person posted, but don't know how to read it.

Thank you for your help.

https://superuser.com/q/441361 for ffmpeg metadata clear.

This command only print readable string opposed to hex edit. Could use tool like sed or perl to replace, but might corrupt file (for example if metadata part of checksum for some data). Note sed and perl need escape some special character because use regex.

strings file.mkv
sed 's/badstring//' file.mkv

hex dump is all raw data from file as hexadecimal number, not much readable. Except for raw string, which strings is better tool for.

Metadata define as all data that is not file data (in this case video), so you talking about metadata. Again, can infer some metadata from video data, but not enough to identify pc. Metadata like encoder version, timestamp when was recorded, recording device/software. Ffmpeg strip all except encoder.
