The EUDI Wallet is Coming: Strategies for Biometric Security
Content
The digital transformation of Europe has reached an apex moment. With the entry into force of the European Digital Identity Regulation in May 2024, the clock is ticking toward a unified digital identity ecosystem. By 2026, every EU Member State must offer a European Digital Identity (EUDI) Wallet to its citizens. By 2027, major private sector services, from banks to large online platforms, must accept it.
For governments and enterprises, this is not just a compliance deadline; it is a shift in how trust is established online. The success of the EUDI Wallet hinges on one critical factor: security. In an era of generative AI and industrial-scale fraud, how do we ensure that the person holding the digital wallet is the legitimate owner?
The answer lies in next-generation biometrics capable of bridging the gap between security and interoperability.
The Timeline: A Race Against Synthetic Fraud
The schedule set by the European Commission is ambitious. Following the adoption of the technical specifications in late 2024, Member States have 24 months to roll out their certified wallets.
● By 2026 (Member States): Every EU nation must provide at least one digital identity wallet to its citizens. This wallet must meet the "Level of Assurance High" standard, requiring the toughest security protocols available.
● By 2027 (Private Sector): Under Article 5f, private "Relying Parties" are legally required to use Strong Customer Authentication (SCA), such as banks, telecoms, and transport services for identification.
● Very Large Online Platforms (VLOPs): Tech giants designated as VLOPs (like Amazon or Facebook) are also mandated to accept the wallet to ensure user privacy and age verification.
Reliable and more secure, face biometrics is arguably the preferred method of authentification for the wallet. However, this rollout coincides with a drastic escalation in the threat landscape. The democratization of AI tools has led to a surge in synthetic identity fraud, with deepfake attacks occurring every five minutes in 2024. Fraudsters are attacking the verification process using sophisticated Injection Attacks and Presentation Attacks.
For the EUDI Wallet to achieve its goal of LoA (Level of Assurance) High, the biometric binding mechanism must be impregnable.
The Two Fronts of Defense: PAD and IAD
To secure the EUDI Wallet ecosystem, "good enough" biometrics are not sufficient. The Architecture and Reference Framework (ARF) and emerging standards like ETSI TS 119 461 mandate a rigorous, multi-layered defense.
1. Defeating Presentation Attacks (PAD)
The first line of defense is Presentation Attack Detection (PAD). This protects against "spoofs" presented physically to the camera, such as high-resolution photos, video replays on tablets, or 3D masks.
The global benchmark here is ISO/IEC 30107-3. To act as a reliable gatekeeper for the EUDI Wallet, a biometric solution must be independently certified to Level 2 (proving resistance against sophisticated artifacts).
2. Defeating Injection Attacks (IAD)
In an Injection Attack, the fraudster bypasses the camera entirely. Using virtual camera software or emulators, they "inject" a digital deepfake directly into the application's data stream.
Traditional liveness detection often fails here because the injected video stream can be mathematically perfect.
This is why the EU has pioneered a new standard: CEN/TS 18099. This technical specification defines the requirements for detecting biometric data injection. Oz is certified by BixeLab under the standards of CEN/TS 18099.
For a wallet issuer or a relying party (like a bank), complying with eIDAS 2.0 means ensuring your biometric vendor is ready for both threats.
The Interoperability Challenge: Cross-Border Trust
One of the core promises of the EUDI Wallet is cross-border interoperability. A student from Portugal must be able to use their wallet to rent an apartment in Berlin; a French citizen must be able to open a bank account in Spain.
This requires a standardized approach to biometric verification. If every country uses a different proprietary standard, friction will destroy adoption. The use of Passive Liveness is emerging as the preferred standard for ensuring this interoperability without sacrificing user experience.
Unlike "active" liveness, which requires users to perform specific gestures that creates friction, Passive Liveness works in the background. It offers a fluid experience that is universally accessible, crucial for meeting the EU's target of 80% citizen adoption by 2030.
Preparing for 2027: A Roadmap for the Private Sector
For Relying Parties, especially banks, telecoms, and Very Large Online Platforms (VLOPs), the mandate to accept the EUDI Wallet by 2027 is a call to action.
Organizations should not view this merely as a regulatory burden. Integrating the EUDI Wallet offers a massive opportunity to reduce the cost of Know Your Customer (KYC) processes. By accepting a government-vetted digital identity, businesses can offload the heavy lifting of identity proofing to the wallet issuer.
Strategic Steps for Preparation:
● Audit your Biometric Stack: Does your current onboarding flow protect against injection attacks? If your vendor isn't testing against CEN/TS 18099 criteria, you are vulnerable to deepfakes.
● Prioritize NFC: For the highest level of security, combine facial biometrics with NFC chip reading of physical documents. This ensures the source data is cryptographically signed by the issuing state.
● Adopt Passive Liveness: To ensure your service is accessible to all EU citizens, regardless of tech-savviness or physical ability, move away from intrusive active liveness challenges.
If your biometric stack today cannot demonstrably stop injection attacks, you will not meet LoA High — even if you pass audits on paper.
Conclusion: Building a Fortress of Trust 🔒
The EUDI Wallet is set to become the gold standard for digital identity globally. But a wallet is only as secure as the lock that protects it.
At Oz Forensics, we understand that compliance is just the baseline. True security requires staying ahead of the threat. That is why our technology is rigorously tested to meet the highest global standards, including ISO 30107-3 for presentation attacks and advanced protocols to detect injection attacks and deepfakes.
As Europe moves toward 2026, the organizations that succeed will be those that build their digital infrastructure on a foundation of verifiable, certified biometric trust.
If your organization relies on digital onboarding, now is the time to stress-test your biometric security. Contact Oz Forensics to learn how our NIST-ready and ISO-certified solutions can prepare your organization for the EUDI Wallet era.
