BioID

BioID offers a specialized facial recognition service designed to secure your digital identities through advanced liveness detection. You can integrate their technology into your existing applications to ensure that the person behind the screen is a real, living human rather than a photo, video, or mask. This helps you prevent identity theft and unauthorized access without requiring specialized hardware, as it works with standard cameras on smartphones and computers.

The platform is built with a strong focus on privacy and data protection, adhering to strict GDPR standards. You can use it for various scenarios including remote onboarding, multi-factor authentication, and self-service password resets. By offloading the complexity of biometric processing to their cloud service, you can implement high-assurance security features quickly while maintaining a smooth experience for your end users.
