Inspect content evidence locally

Cryptographically inspect C2PA image provenance manifests and uncover invisible zero-width Unicode telemetry. Strict local client-side computation — zero bytes transmitted.

$ All verification operations execute locally in WebAssembly. Network transmission, telemetry trackers, and third-party scripts are completely disabled on this route.

Mathematical Security Guarantees & Boundaries

What Local Verification Cryptographically Proves

  • Presence and syntactic integrity of an embedded C2PA claim manifest
  • Mathematical validity of cryptographic digital signatures against local public keys
  • Precise byte-level offsets of zero-width, bidi, joiner, tag, and hidden Unicode characters

What Local Verification Cannot Determine

  • Whether content is synthetic AI vs human-created in the absence of signed provenance
  • Whether an uncredentialed image has undergone malicious pixel alteration
  • Vendor authenticity without an established root certificate authority trust chain
  • Statistical token-distribution or proprietary model watermarks without reference keys
