When we digitise a primary source - a document, a photograph, an object - we capture more than the image. We also record how it was made: when it was captured, with what device and software, and by which institution. That information is bundled with the file and sealed with a digital signature.

Because the seal is calculated from the exact content of the file, any later change - even a single altered pixel - breaks it. That is what "tamper-evident" means: you cannot quietly edit a credentialled file without the change being detectable.

This follows C2PA, an open, international standard for content provenance and authenticity. It is the same approach used across journalism and media to tell genuine material from manipulated or synthetic copies. It is open and vendor-neutral, so anyone can verify a credential with public tooling - they do not have to take our word for it.

An archive, library, gallery or museum exists to be trusted. Researchers, courts, journalists and the public rely on what we hold being a faithful record of the original. In a world where images and documents can be convincingly altered or generated, that trust can no longer be assumed - it has to be demonstrable.

Content credentials let us demonstrate it. Every digitised item can be checked back to the moment of capture, independently and without contacting us. This turns our collection into a verifiable anchor for truth: a fixed point that other people can measure a suspect copy against.

It also protects you. If a file claiming to come from us has been altered, the credential will reveal it. If a file genuinely came from us, the credential will confirm it. Either way you are not left guessing.

هناك ثلاث طرق للتحقق، اعتمادًا على ما يتوفر لديك أمامك. لن تحتاج أبدًا إلى حساب، ولن نرى أو نحفظ أي شيء تتحقق منه.

بما أنك تستخدم أي أداة، فإن النتيجة تعود كواحد من ثلاثة نتائج بسيطة.

نظراً لاستخدامه لمعيار C2PA المفتوح، لن تكون مقيداً بأدواتنا أبداً - يمكن لأي شخص التحقق بشكل مستقل من أي من اعتمادات المحتوى الخاصة بنا باستخدام برامج C2PA العامة.
