About SureMark Digital™

Since 1991, a pioneering series of papers and patents, written with Dr. Stuart Haber and Dr. Scott Stornetta, laid the foundation for Bitcoin and other digital currencies. Considering the growing specter of deepfakes and declining public trust of information found online, we have developed SureMark Digital ID™ to enable people to be able to tell the difference between genuine and AI deepfaked media.

No-one can stop deepfakes from being created, but a digital credential from SureMark Digital applied to all of the media you post will make it easy for the public to tell the difference between your legitimate content and fake media created to attack your reputation.

Whether you’re applying for a SureMark Digital ID or following a SureMark Digital ID™ holder, our hope is that our collective efforts will diffuse the destructive nature of AI Deepfakes and limit their influence!

Assert your identity.

Claim your content.

Control the narrative.

Disarm the deepfake.
