Where? What Software? What Archive?
So many photos of peoples lock screens with clearly visible faces...
Am I not understanding your question? It's one system - and either their archives are public on purpose, or their endpoints are simply unsecured.
I worked alongside the lost&found office at an old job, we just had a spreadsheet and a book...
Anyway the /lost+found link would be its inode number, I think. And then you could recover it after fsck had relinked it into the hierarchy. It would have to put them there, because it had no idea what pathname it had used when it was a real file.
