The next era of digital trust
will be about proving origin
Having secured the origin of physical objects, PROOFTAG Digital is now developing ways to establish the origin of information in a world where AI can make false content appear believable and stolen data can enable convincing impersonation.
DATA PROTECTION
Generative AI makes falsehoods increasingly plausible, while stolen data can be turned into a means of impersonation. This white paper proposes strengthening digital proof around a central requirement: proving the origin not only of what is transmitted, but also of the request itself.
This bilateral proof of origin applies to both the sender and the requester, while distinguishing their identity, authorisations, the intended recipient and the purpose of the exchange. It complements authentication, integrity, electronic signatures, traceability and provenance, without replacing them.
For more than twenty years, PROOFTAG has protected the origin of physical objects using the Bubble Tag™, an observable and measurable physical singularity. PROOFTAG Digital is now preparing to extend this expertise to information by exploring a physical-digital proof of origin. The ambition is to strengthen trust through a verifiable physical origin, without claiming to certify the truth of the content or unnecessarily exposing personal data.
