A signature attached to a content attesting to its origin and integrity, to authenticate the true rather than detect the fake.
Cryptographic provenance designates the technologies that attach to an image, a video or a document a signature certifying its origin and integrity, and allowing the content to be traced back to its source. Faced with AI-augmented fraud, it embodies a change of paradigm, reversing the burden of proof by requiring a content to be natively authenticated rather than exhausting oneself proving it false. This approach recognises that detecting the fake is a race lost in advance, the generator always having a head start over the detector. It nonetheless supposes shared standards and an ecosystem of trust that no insurer can build alone, as well as a transformation of practices, the policyholder having to capture their evidence through certified applications.
A certified application signs the photograph of a damage at the moment of its capture, cryptographically attesting to its authenticity, which spares the insurer from having to prove it was not fabricated.
