The Future of Age Verification: Your Face Never Leaves Your Device

Age verification requirements are becoming mandatory across multiple jurisdictions. The focus has shifted from whether platforms implement age checks to how they handle biometric data and whether collection is necessary. Over 30 age assurance regulations are currently active globally. In the UK, the Online Safety Act mandates rigorous age verification measures, with restrictions on under-16 access to social media set for implementation in 2027. Australia enforced similar rules in December, while Brazil’s Digital ECA became effective in March 2026. In the U.S., half of the states now require some form of age verification.

Facial age estimation has emerged as a practical solution for compliance. It eliminates the need for government-issued IDs or database queries, making it accessible for users without documentation. Incode’s data indicates that this method is chosen by 80% of users in regulated markets over alternative approaches. However, it requires capturing facial data, a process that raises privacy concerns.

Server-based age estimation poses significant risks. The Identity Theft Resource Center reported 3,322 data breaches in the U.S. in 2025, a 79% increase over five years, with supply-chain breaches doubling during the same period. Consumer surveys reveal 63% of individuals are deeply concerned about biometric data collection. Meanwhile, fraud techniques are evolving rapidly. Incode observed a surge in agentic fraud, where AI-driven attacks accounted for 3% of attempts in 2024, rising to 40% by early 2026, with projections exceeding 90% within 18 months.

On-Device Age Estimation: Verifying Age Without Transmitting Biometric Data

Incode’s latest solution processes facial age estimation and passive liveness detection directly on the user’s device. This approach ensures that facial data is never transmitted or stored. Platforms can meet global age assurance standards without requiring users to share their face with external servers.

Privacy by policy versus privacy by architecture

Industry practices often rely on privacy policies to outline data handling procedures. However, these are legal documents that do not provide technical safeguards against breaches or insider threats. In contrast, privacy by architecture embeds security into the system’s design, ensuring sensitive data remains inaccessible. If facial data is never transmitted or stored, it cannot be intercepted or stolen.

A $100 million investment in on-device solutions

Incode allocated funds to enhance on-device processing capabilities, advance research in privacy-preserving technologies, and expand engineering resources. The first product under this initiative, On-Device Age Estimation, launched in July 2026, marking the first time the company’s models operate entirely on the user’s device.

Key components of the solution

The system employs two models on the user’s device: facial age estimation and passive liveness detection. These analyze the user’s face locally, without sending data to servers. Only the verification outcome—whether the user meets the age threshold—is transmitted. If the check fails, alternative methods are offered. To enable this, Incode reduced model sizes using knowledge distillation, a technique where smaller models mimic the accuracy of larger ones. This allows the system to run efficiently on standard devices without specialized hardware.

Since data is processed locally, neither Incode nor platform operators can access biometric information.

Server-side safeguards for session integrity

While on-device processing prevents data exposure, it cannot fully eliminate session tampering, such as injected camera feeds or manipulated devices. Incode’s server-side layer analyzes session metadata—timing, device characteristics, and connection details—to detect anomalies. This data does not include facial information but ensures fraud detection and compliance. Incode’s security framework has demonstrated 99% spoof detection accuracy against deepfakes, injection attacks, and replay attempts. It has identified over 1 million face-related attacks on its platform in 2026.

Collaborative fraud prevention without data sharing

The second phase of Incode’s initiative addresses data sharing between institutions. Traditional methods of pooling fraud data create centralized vulnerabilities. Instead, Incode integrated technology from Identiq, which enables organizations to share fraud signals without exposing customer data. This approach avoids central data repositories and third-party brokers.

Industry adoption and compliance standards

Incode’s solution aligns with multiple regulatory frameworks, including SOC 2 Type 2, ISO/IEC 27001, HIPAA, FedRAMP, and the Age Check Certification Scheme. The company has processed over 7 billion trust checks and now offers a product that keeps biometric data on devices while maintaining robust fraud detection.

Regulatory and user demands are reshaping age verification practices. As laws expand and privacy expectations grow, the industry must balance compliance with data protection. Incode’s approach represents a shift toward systems where user privacy is embedded in design rather than reliant on post-hoc policies.
