What Is Image Immunization?

Most photos travel further than the person in them expects. Once an image is posted, it can be copied, and today it can also be fed into AI tools that learn to recreate or reuse the way someone looks. Eterna Image Immunization (EIP) is Eterna's proprietary pre-publication image protection technology, developed through Eterna's internal research and development and currently under validation, designed to help reduce the risk of deepfake creation, AI identity replication and unauthorized likeness reuse by preparing an image before it's published.

The simple version

Normal image → publication → possible AI reuse. That's the path most photos take today: a photo is taken, it's shared or published, and from that point on it can potentially be picked up and reused by AI systems without the person's knowledge.

EIP's approach: authorized image → pre-publication protection → publication. EIP is applied before the image goes out, at the point its owner authorizes it for use, so the protection is already in place by the time anyone else sees it.

A simple analogy

Think of it like a watermark, but invisible and aimed at machines instead of people. A visible watermark tells a person where an image came from without changing what they see in it. EIP is designed to work the same way for AI systems: the image looks completely normal to a person, while becoming harder for common AI systems to reuse or identify from.

Who this is for

• Public figures, whose images circulate widely and can be targeted for impersonation.
• Executives and founders, whose photos appear in press, investor and company materials.
• Creators, who share images across platforms with limited control over reuse.
• Students and families, for everyday photos, not just high-profile cases.
• Organizations, protecting images of the students, staff or members they represent.

What this isn't

EIP isn't a guarantee that an image can never be misused, and it isn't a replacement for Eterna's existing detection and response services. It's designed to be an additional layer, applied earlier, alongside the protection Eterna already provides.

Where this is going

EIP is currently undergoing continued validation. Protection effectiveness may vary across systems, transformations and use cases.
