A-Tag™ · Proof a file was made in human

Did a human make this?

…and protecting the copyright of online creators.

Human provenance across digital content. A-Tag™ marks what a real, present person (not a bot) uploaded, created, or published — signing a file with physiology, so authenticity travels with the content. The user can also tag files already present on their mobile device. A-Tag™ is a fully NIST compliant encryption product. A-Tag™ is fully auditable, stored on the blockchain, resists compression from all online posting & can be verified by the recipient.

How it works

Copyright for creators, signed by physiology.

As a person captures or decides to upload content, A-Tag™ reads their neuromuscular micro-vibrations and binds a unique, encrypted, physiological signature to that moment.

Three steps — a living human-mark waveform, sealed inside a certificate, then verified intact at the endpoint.

Capture

During ordinary creation, A-Tag™ senses human micro-vibrations from the device.

Sign

A physiology-derived tag is computed on-device and bound to the content. This crypto-tag is computed according to NIST standards.

Verify

Anyone can later check the unique tag to confirm a real human takes responsibility for the content.

What you get

Trust in the age of synthetic media.

  • Proof of human copyright at the point of capture or upload
  • On-device signing via physiology
  • A portable tag that travels everywhere with the content and stored on the blockchain (Polygon)
  • An app for users to prove they are behind their content
  • SDK / API for creation tools and platforms
Use cases

Where provenance matters.

Newsrooms & journalism

Mark original footage and reporting as human-captured, defending against synthetic fakes and manipulated media.

Creator platforms

Let creators prove their work is human-made, distinguishing it from AI-generated uploads at scale.

Legal & evidentiary records

Establish that documents, photos, and statements were produced by a present human, strengthening their evidentiary weight.

Marketplaces & listings

Verify that reviews, listings, and submissions come from real people, not content farms or bots.
