Likeness consent registries and APIs compared

Yes, there are registries and APIs you can query for likeness consent before generating a real person's face or voice, but they do different jobs. Some answer before you generate, some hold a person's declared wishes, some find deepfakes that are already out there, and one is a provenance standard for labelling output. None is a government registry, none grants right of publicity, and not being listed anywhere is not consent.

Which tool for which job

They end up in the same table, but they answer different questions.

Rightis

Official site
What it does

A public registry of what a rights holder allows, requires approval for, or refuses for their face, voice and persona. On top of it you sign a licence and log the uses made under it.

Who it is for

People register themselves, and some holders are managed by their agency. Lookups answer only for people who chose to be listed. The ones asking are developers building generation features and AI agents.

How you check before generating

Returns a decision for the described use and a next_action. Even allowed is not free use: it leads to a licence request.

Cost

Registering, searching and requesting a licence are free. A fee applies when a licence is signed. The keyless public endpoints are rate limited.

Who runs it

A private service run by The Backers Inc.

RSL Media, Human Consent Registry

Official site
What it does

A public registry where a person declares how AI may use their name, image, voice and movement. The choices are allowed, allowed with terms, and prohibited.[1][5]

Who it is for

Individuals register themselves, and agents, guilds and managers can register through an approved pathway, according to press reports. Reports describe it as open to people in the US or EU.[4][5]

How you check before generating

Declarations are made machine readable through the Human Consent Standard (HCS), an extension module to Really Simple Licensing (RSL). Each person gets an identifier (HCSI) and records are published in bulk through HCS sitemaps. A licence server path for dynamic authorisation is to be specified in the final spec. The spec is a draft dated 2026-08-08.[2][6]

Cost

Free for individuals registering on their own behalf. Press reports note that AI companies are not required to check it and compliance is voluntary.[1][4][5]

Who runs it

Run by a public benefit nonprofit (Human Consent Foundation). RSL Media was co-founded by Cate Blanchett and launched in June 2026. rslmedia.org redirects to humanconsent.org.[1][4][3]

Loti

Official site
What it does

A likeness protection service that tracks a person's face and voice across the internet and helps take unauthorised content down. For generative AI it offers Interchange, for licensed use of protected likenesses.[7][8]

Who it is for

Everyone, and public figures such as actors, musicians and athletes. The home page lists IP protection for developers as coming soon.[7]

How you check before generating

Interchange takes two API calls. Before generating you submit the prompt and Loti identifies protected likenesses, checks the generation rules and, if approved, returns a price estimate. After generating you submit the output for final approval. Authentication is an x-api-key header.[8][9]

Cost

Tracking your face and voice is described as free. Interchange returns a price estimate for each approved generation and records a billing event on final approval.[7][8]

Who runs it

Not found in public materials.

Vermillio, TraceID

Official site
What it does

TraceID monitors for use of name, image, likeness and IP, manages takedown requests on the rights holder's behalf, and manages licence terms and payments. It uses proprietary fingerprinting to detect IP in altered or AI generated content.[10][11]

Who it is for

Creators, studios, talent and music labels. It has a partnership with the talent agency WME.[10][12]

How you check before generating

Not found in public materials.

Cost

Not found in public materials.

Who runs it

Raised a $16 million Series A led by Sony Music in March 2025.[11][12]

C2PA, Content Credentials

Official site
What it does

An open technical standard for establishing the origin and edits of digital content. Content Credentials carry that record. It answers where and how a piece of content was made, not whether a person allowed the use of their likeness.[13]

Who it is for

Publishers, creators and consumers of content.[13]

How you check before generating

Not found in public materials.

Cost

Not found in public materials.

Who runs it

Its steering committee includes Adobe, Amazon, BBC, Google, Meta, Microsoft, OpenAI, Sony and TikTok, among others.[13]

What none of them does for you

  • Not registered is not cleared. Likeness rights and the right of publicity exist without registration, so absence from a registry only means that registry has no record.
  • A registry tells you what a holder has said. It does not replace a legal judgement, and this page is not legal advice.
  • One person may be listed in several places. Checking before generation, finding misuse and labelling output are different jobs, so they can be used together.

Frequently asked questions

Is there an API to check likeness rights?
Yes. Rightis has a keyless public decision API, a keyed check API, and an SDK and CLI on npm. Send a Rights ID and a described use, and it returns a decision and a next action. Loti's Interchange also offers an API that authorises a prompt before generation. Both are summarised on this page with sources.
How do I check consent before generating a real person's face or voice?
Check whether the person allowed this use, requires approval, or refused it, and check training separately. Allowed still means you request a licence, and refused means you do not generate. If the check fails, treat the person as not cleared.
If a person is not in any registry, can I use their likeness?
No. Likeness rights and the right of publicity exist without registration. Absence from a registry means that registry has no record, not that you have permission. Ask the person or their representative directly.
How is Rightis different from RSL Media's Human Consent Registry?
The Human Consent Registry is a nonprofit registry where people declare allowed, allowed with terms or prohibited, published through the machine readable Human Consent Standard (a draft). Rightis answers the same question through a keyless API with a decision and a next action, and adds licences and a usage log on top. A person may be in both, so checking both is reasonable.
Does C2PA tell me whether a person consented?
No. C2PA is a provenance standard that records where and how content was made. Use it to label what you generate, and check consent separately with a registry or the person.
