AURA — Open Proof and Provenance Standard for Digital Assets

Open standard for verifiable proof of origin for human, hybrid and AI-generated works
AURA-STANDARD v1.1.0 — published open standard for review, interoperability work and controlled pilots

What is AURA?

AURA is an open proof and provenance standard for digital assets. It provides a verifiable way to document origin, integrity, timestamped declarations, rights-related signals and independent verification in AI-related environments.

AURA establishes technical facts. It does not determine legal ownership, originality, infringement, liability or actual AI use. Legal qualification remains for institutions, auditors, regulators or courts.

Standard, Pilot and Verifier

AURA is the open standard.
AUTHENTICA / LockDNA is the first pilot implementation.
AURA-VERIFIER is the independent verifier.

AUTHENTICA is a pilot implementation and is not the standard itself.

Scope & Principles

Origin proof at creation: origin is declared and anchored when the work is produced
Cryptographic guarantees: verifiable integrity (hash) and tamper-resistant timestamps
Open architecture: separation between the AURA standard and independent implementations
Tool-agnostic design: no proprietary platform, vendor, model provider, repository host or software assistant is required
Designed for European frameworks: copyright, AI regulation, TDM opt-out, cultural sovereignty

AURA is non intrusive and does not modify the digital asset.

What AURA Does (and Does Not Do)

AURA Does

Define a structured, machine-readable AURA Manifest for origin, rights and integrity
Enable independent verification of origin and timestamps
Expose transparency signals for AI training and TDM rights
Allow optional references to file-native multimodal signatures

AURA Does Not

perform content recognition or fingerprinting
maintain any fingerprinting database
embed code, watermarking or DRM inside files
analyse the content of the work
make decisions about licensing or remuneration
decide legal ownership, infringement or liability

AURA provides a verifiable technical artefact. Law, audit, regulator or court decide legal qualification.

Canonical schemas

AURA manifest v1.0.0 — frozen canonical schema
AURA manifest v1.1.0 — reference_anchor and prior_evidence evolution
v0.1 material is retained as legacy / superseded public draft

The manifest does not require access to the content itself.

Governance

AURA is published as an open standard (AURA-STANDARD v1.1.0). Future governance may evolve toward an open, transparent and multi-stakeholder process inspired by recognized open standardization practices.

Key principles:

No single company owns or controls AURA
No single platform, vendor, institution, model provider or repository host controls AURA
Implementations remain independent if they comply with the published specification
Discussions occur in writing and transparently
The Charter of Independence prevails over any future governance model

AURA is designed for long-term institutional governance without capture by a single actor.

Why Europe Needs AURA

The European Union has a strategic mandate to protect:

cultural diversity
copyright and authorship
transparency of rights management
lawful use of works in the AI era

With generative AI, large-scale datasets and automated transformations, origin has become a foundational issue.

AURA provides:

verifiable proof of origin for human, hybrid and AI-generated works
machine readable transparency for AI training and dataset use
cross border interoperability between platforms, CMOs and institutions
auditability and technical traceability compatible with EU law

AURA does not replace existing regulations; it provides the technical layer that enables their implementation.

Interoperability

AURA complements does not replace:

ISRC / ISWC
DDEX metadata frameworks
C2PA (content authenticity)
National copyright registries

AURA focuses on origin declaration, manifest integrity and rights-reservation signals. It complements content-authenticity systems without replacing them.
