About
A registry for work that needs to be believed.
TataTech seals documents and digital presence with an instant fingerprint, so a creator can show that a piece of work existed, unchanged, at a known moment — and anyone can check it without an account.
Sealed, not promised
Every record carries a SHA-256 fingerprint computed in your own browser. The registry stores the hash, never a copy of your private work.
Anyone can check
Each seal has a short verification code, a QR code and a public page, so a client, a gallery or a stranger can confirm a file in seconds.
Members in the open
Creators hold a public member code and a profile in the directory, so the work and the person behind it can be found in the same place.
What TataTech does
You upload a file or name a web address, and TataTech computes a fingerprint of it — a SHA-256 digest produced in your browser. The fingerprint, a title, the details you choose to publish and the time of sealing become a certificate with a short verification code. The file itself stays private; only the fingerprint is public.
From then on, anyone holding a copy can compare it against the sealed fingerprint on the public verify page or in the Proofs directory. If the two match, the copy is the same work that was sealed. If they differ, something changed after the seal — and the page says so.
Who it is for
Independent artists, designers, illustrators, photographers, writers and small studios who hand work to clients, enter open calls, license images or pitch for commissions. It is equally for the people on the other side of that exchange: clients and institutions receiving creative work who want a cheap, quick way to confirm that what they were sent is what was signed off.
Members hold a tier that sets a monthly fingerprint allowance, appear in the public registry under a member code, and can refer other creators through the affiliate programme.
Who builds it
TataTech is built and run by the small independent team behind tatatech.digitalexpert — designers and engineers who work on trust and provenance tools for creative businesses. The same people answer the support mail, review membership requests and handle revocation requests, so the registry stays accountable to the members who use it.
Security and privacy are part of the build rather than an add-on: fingerprints are computed in the browser, documents are stored privately, and every public record shows exactly what it does and does not prove.
