# Humark

> Humark issues the Pulse Signature, a biometric attestation that a specific human, using their own biometrics, signed a specific work at a specific time. A biological defense system for creators against AI scraping and identity erosion. Operated by AU-SVRN under an editorial-independence charter.

Humark binds a creator's biometric signal to the files they produce, mints a Pulse Signature attestation that travels with the work, and gives publishers, marketplaces, and audiences a verifiable answer to one question: did a specific human attest to this? The Pulse Signature is a cryptographic seal stitched to C2PA content credentials and to an append-only registry. The biometric signal stays on the creator's device; the registry stores only the public attestation. Humark is pre-launch as of 2026; the iOS mobile app, the REST API v1, and the editorial layer at /articles are live.
