Strengths

  1. AgeKey offers privacy-preserving reusable proof-of-age tied securely to user devices.
  2. AgeKey supports interoperability across platforms while minimising tracking through consent-based revocable credential sharing.
  3. Opale.io exemplifies orchestration-enabled architecture, integrating multiple providers without exposing personally identifiable information.

Summary of Results

AgeKey showed technical promise and privacy alignment but lacked broad testing, integration and adoption, limiting its system-level readiness and maturity.

IMPORTANT UPDATE

Opale.io was acquired by k-ID in Autumn 2025 and its technology now operates under the OpenAge Initiative. OpenAge provides a secure and privacy preserving credential system based on AgeKeys, enabling users to save an age proof and reuse it across participating platforms and Age Assurance Providers in about 3 seconds. The underlying double anonymous approach originally designed by Opale.io is maintained and now deployed at scale in France, Italy, the UK, Australia, and other markets.
More information about the initiative is available on openageinitiative.org, and anyone can create and test an AgeKey directly on agekey.org.

Full technical documentation is available on docs.agekey.org.“

Privacy Policy

In addition to the structured Practice Statements, the Trial also reviewed publicly available Privacy Policies for all participating providers. This formed a key part of the Trial’s ethical due diligence and helped assess how well declared practices aligned with actual documentation and observed system behaviour.

Practice Statement

Practice Statements are formal documents submitted by participating providers, outlining how their systems function and how they claim to meet specific expectations under international and domestic standards. They offer providers an opportunity to articulate their system’s design in their own words — similar to a ‘statement of practice’ or ‘system disclosure’ used in certification and compliance contexts.

Interview

As part of the Trial’s commitment to transparency and accuracy, the team prepared a written summary of each vendor interview, capturing key points regarding system design, functionality and implementation claims. These summaries were shared with participants for review, allowing them to check, verify and suggest corrections where necessary.

Test Report

Individual Vendor Test Reports were developed for each participating provider. These reports formally document the results of the functional, usability and security evaluations carried out during the Trial and are intended to support public understanding, regulatory scrutiny and future conformity assessment or certification processes.
