Re: [projectvrm] Watermarking personal data

[sylvain willart < >]

I heard a presentation on this very subject at a conference a year ago. It was done by INRIA researcher (INRIA is a national research institute just like CNRS). The person who was giving the speech was Ioana Manolescu ( http://pages.saclay.inria.fr/ioana.manolescu/ ).

For what I understood, it was about metadata. She seemed to say it was possible to write metadata in a way it could not be (easily) erased, so one could follow the "trail" of the data. But frankly, I didn't dig too deep in that issue.

Until the data remains on my side and I have a request from an external company to access it  or there is a mandatory Meta data flag into databases and data exchange platforms that indicates the source and destination of the data exchanged, to my knowledge, there are no solutions to that problem today.
