Apertrue

Apertrue proves that a photo or video is authentic: captured by a real camera or generated by a declared AI tool, and not tampered with since. It does this without revealing who took it, where it was taken, or what device was used. It does this using zero-knowledge proofs: mathematical proofs that verify a statement is true without revealing the underlying data. The cryptography runs entirely in your browser. Nothing sensitive ever leaves your device. The aggregated proof is verified on Aztec. Aztec is a privacy-preserving blockchain. Your proof is verified inside a private function. The result is an encrypted note that only you can read. No one else can see what you verified or link it to your identity.
