This is great for anyone creating original content published on the net. Far more powerful than the standard © copyright symbol, it registers and declares you as the irrefutable owner of your work.

What if a PDS became more than a repository for posts? We propose using AT Protocol as a creator-controlled publication layer for declaration metadata describing digital works, making rights, provenance, and other trusted metadata independently verifiable and easier to discover.

REPORT on copyright and generative artificial intelligence – opportunities and challenges www.europarl.europa.eu/doceo/docume...

Making digital signatures a standard practice for creators will take some time, but we're getting there. – First, we had to establish the ISO standard for the content fingerprinting / pHashing, because signing cryptographic hashes doesn't work for long form content. ISCC solves that. @liccium.com 1/

Boris@bmann.ca · 5mo ago

Yes.

Content use, monetisation, trust, and transparency start with robust, open, standardized content identification – without robustly identifiable digital assets, attribution, licensing, and compliance cannot be reliably automated or enforced across systems. ISCC (ISO 24138) provides the foundation.

Entire communities of media and tech professionals are debating content provenance, rights and metadata, PIDs – yet often without addressing the basic question: what asset are we even talking about? ISCC (ISO 24138) addresses this "Asset-Vergessenheit" by providing the reference to the file.

Excellent! This is the way. – @liccium.com is providing content-based IDs / fingerprints (ISCC codes) to that ecosystem allowing authentic and original digital media to be digitally signed by self-sovereign accounts (DIDs) – or synthetic content to be properly labeled.

Introduction | Liccium

docs.liccium.com

Third parties, such as AI model providers, can identify the user intent only by having access to the media assets by generating the ISCC, matching nearest neighbours and resolving the manifest. – We presented our approach at the IETF conference on AI control.

How it works: ISCC codes are generated from text or other media assets in blobs, the user intent is added to form a manifest, which is digitally signed and publicly declared on federated registries. Verifiable credentials bind did:key, did:plc and other attestations to provide proper attribution.

With @liccium.com we are working on a way to bind rights and metadata ("intend") to the actual content, resp. The content-derived ISCC (ISO 24138). These declarations may include AI preferences: tdmai.org. Your RFC could becime a Liccium plugin.

We have changed the handle to @liccium.com. – DNS verification is a fairly simple, efficient and secure way to establish trust in handles and posts. For this reason, we use DNS verification as one method to ensure this level of attribution for content declarations on Liccium.com.

A publisher/repository could bind this information/update to the ISCC and make a public declaration. Then it this update for one version could potentially reach a user for all versions.
