DIGITIZED as NEW VERSION
- the tracking number of a file is usually used to track the from and use for, built-in many editor software, here say the number is the id active not by user(and don't know), which is a bad thing for personal privacy.
- id most used for classification, and classification is only used to output different results, then world are no longer objective and become smaller.
- here is the id insert example:
- meta hack
- write id at specific non-functional block positions in the file, such as specific blocks for PNG, JPG. or as meta data for movie file.
- replace the codec minor version as id, most decoder check that the major version is compatible and work fine.
- use specific nanoseconds or milliseconds at several specific time frames of video or audio to form numerical numbers or data.
- content hack, anti-edit
- in specific frame, implantation of very insignificant chromatic aberration data in a specific channel of a image, usually low-brightness-possibility the blue channel.
- data as color put in video image first line, in 1080p video this just 0.5 line at border for 0.03 second, user won't notice at all.
- modify some important(never got cut) frames, add XOR data in the middle of the right(may resize but never got cut), because it is only XOR data so very short, it indicates the correction value after the color of the fixed position of the current frame image is combined into the data.
- embed id at a specific time in the audio, on example 48KHz audio has 48000 * channels * bits of data per second, and modifying the value of some of these samples does not tell the difference at all.
- these are just a few examples, no one can identify them all. v2mixer never have tracking number(never here doesn't count the 3rd codec, such hardware acceleration).
- unlike the self-evidence mentioned above, many video sties have signature scanning part by part as content-id to warning repeat, but also can't use for prove, that may you post to siteA but auother guy copy to siteB.
- anywhy, to prove that you are the author, keep the original material, this is the best way.
