Who’s in the Ad?

Every ad knows which ad it is. Not who’s in it. Commercials have carried a standard identifier for decades. Ad-ID tells the supply chain which ad ran. EIDR tells it which program ran around it. Neither says who is on screen: the athlete, the actor, the voice, the face the campaign was built on. That’s the gap HAND fills. For brands, agencies, ad tech platforms and measurement companies, it means talent attribution checked against a persistent, public record.

Every ad with a real person’s likeness in it needs an answer to who’s in it?

Not a pivot.
A long game.

Before HAND existed, its founder was working on the same problem from the advertising side.

2010 – 2018
CIMM’s TAXI initiative (Trackable Asset Cross-Platform Identification) brought content and ad identification together: register programs with EIDR, register ads with Ad-ID, and keep both IDs with the asset wherever it goes.
2018
SMPTE, working with CIMM, published the Open Binding of Identifiers standards, OBID and OBID-TLC (ST 2112-10 and ST 2112-20).
February 15, 2019
An ATSC 3.0 field trial in the Phoenix area broadcast EIDR IDs and Ad-IDs over the air to commercially available smart TVs.
December 2019
HAND founder Will Kreth, who represented EIDR at CIMM through TAXI and TAXI Complete, co-authored a peer-reviewed paper on the work.
William Kreth and Francois Modarresse, “A New Method for Effective Quantitative Audience Measurement,” SCTE•ISBE Journal of Digital Video, Vol. 4, No. 1 (December 2019), pp. 5–19.

TAXI showed that content and ads could be identified together across the chain. It never named the people in them. HAND is the missing third ID.

The rules just changed.
For ads, specifically.

Synthetic performers, disclosed
In effect since June 9, 2026: ads that use an AI-generated synthetic performer must say so.

When an ad features a real person’s licensed likeness rather than an invented one, the people buying, clearing and running it need a way to tell the difference. A consented, resolvable record of who that person is gives them one.

We proved it in the file.
Next, at the ad call.

IBC 2024 carried HAND IDs through the file and the playback chain, end to end. Advertising runs on ad servers and the ad call. That’s the next proof, and it’s a co-funded one. Partners bring a live ad server or measurement stack, engineering time, and a share of the cost. HAND brings the registry, the IDs and the consent records. Both sides walk away with results they can show their own buyers.
