Liccium Innovations
Trust begins with a signature
Instant verification
Users and platforms can cryptographically verify claims, attribution, the integrity and authenticity of the content and metadata.
Secure metadata binding
Liccium enables creators and rightsholders to inseparably bind public and verifiable claims to their content. – Rights and metadata will travel with the content.
Fingerprints on Federated Registries
Resolvable, verifiable, and transparent by design
Liccium enables creators and media organisations to issue signed declarations that bind ISCC fingerprints to rights, metadata, and identity credentials. These declarations are published to federated registries – resolvable, verifiable, and open by design.
TDM·AI
Creators can declare AI preferences for their content in a standardised and verifiable way – binding their opt-out declarations to the fingerprint of their works.

Built on open standards and specifications
Every Liccium building block is based on an open, published specification – some already ratified as international standards, others emerging through W3C and IETF. Together they let you identify content, prove authorship, and declare rights in ways that stay verifiable and interoperable beyond any single platform.
ISO – ISCC
ISCC is a content-derived identifier generated directly from a media file, standardised as ISO 24138:2024. The ISCC combines cryptographic and similarity-preserving hashes, so content can be identified and matched across file formats and minor modifications – without a central registry or manually assigned numbers.
W3C – Verifiable Credentials
A digital identity layer based on the W3C Verifiable Credentials data model. X.509 certificates and verifiable credentials authenticate the source of each declaration, so attribution and authorship claims can be verified independently – pseudonymously if preferred.
W3C / IETF – AI Training Preferences (opt-out)
Asset-based, machine-readable opt-out declarations for text and data mining. Reservations are bound to the content itself rather than a web location, so a rightsholder's opt-out travels with the asset. The approach follows the W3C TDM Reservation Protocol (TDMRep) and the IETF AI Preferences (AIPREF) work – both still emerging specifications rather than ratified standards. Liccium will align its declarations with the IETF vocabulary as it is finalised.
