GBG

VENDOR CASE STUDY

GBG offers a real-time, multi-layered age verification system combining document checks, facial biometrics, credit agency data and liveness detection. Their solution includes in-person verification options and supports facial age estimation for users aged 6+, without retaining personally identifiable information (PII), making it suitable across multiple regulated sectors.

Strengths

Highly accurate and fast, even under low lighting and varied image conditions in real-world testing environments. Flexible integration with client systems via APIs and SDKs, enabling easy deployment at scale.

Summary of Results

GBG performed well in live testing, demonstrating strong accuracy and fraud detection capabilities. It was especially effective in online gambling and retail sectors. However, guidance for relying parties was limited, creating a risk of privacy misconfiguration. The system is TRL 9, with ISO-aligned privacy and data minimisation features.

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.
