B.A.T. — Bureau des Affaires Temporelles. Written in 1988, published by Ubi Soft in 1989: one of the studio's first major successes. I co-wrote it — and I am the sole author of all its artwork. I was twenty.
Copied, diverted through the grey market as far as Taiwan. Neither the author nor the publisher could follow an object once released into the world. The technology did not exist.
It exists today.

You own it: impossible to prove where the object comes from, or that it is yours. You create: the work circulates and gains value — without you.
And now, you own nothing at all. Music, films, games: you are no longer sold a work, you are sold a revocable licence to access. A title disappears from a catalogue — character, universe, hundreds of hours: gone.
The first generation with nothing to pass on.
Fortunes change hands
on proof that does not hold.


Seal · recognise · bind · transmit.
No cloud, no middleman.
For the author, sealing a work's origin: dated, located, signed. The protocol provides three exposure modes — Anonymous · Identified · Hybrid (identity revealable at will).



At handover, the deed is signed by both parties with a qualified electronic signature — the same value as a handwritten signature in court.
RELICKEEPER is not a gadget: it is the tool for a real private-treaty transaction. European eIDAS framework (qualified signature) · designed model.

Verified identity (Stripe Identity) + qualified electronic signature (Yousign, eIDAS): proof of authorship that is dated, named and enforceable, sealed onto the work.
The certificate does not “grant” copyright — it is its strongest proof (French IP Code · Berne Convention). Public mode · designed model.

RELICKEEPER holds only one key out of three — all three are required. Digital sovereignty: your data stays in France, on your devices, never on a foreign cloud — and it works offline. Lost card ? 24 words restore everything. The same standards as banks and governments · designed model.


RELICKEEPER starts in entertainment, where the team has 40 years of contacts. Our gallery relickeeper.art shows the tech for real — and sells it.
We don't bring yet another tech to luxury. We add a memory to the objects fans already love.
The works are co-created — and that is precisely the demonstration: the protocol records who created, when, and with which tools. In the age of AI, origin is not declared, it is proven.
