Biometric Sensor

Biometric sensors are a mechanical or electronic technology that captures biometric data (i.e. the face, palm print, or iris) digitally in a way that can be turned into a biometric template. 

So for example, the biometric sensor for the face is a device’s camera. For fingerprints, it is a fingerprint pad/sensor. For the voice, it’s a microphone. 

Biometric technologies such as face matching, liveness detection, and advanced AI techniques compare the biometric template against the user that is asserting their identity to determine if it is the right person (not an impostor) and a real person (not a presented spoof). Additionally, iProov Genuine Presence Assurance® technology creates a one-time biometric to ensure the authentication process is happening in real-time (not a digital injection attack using a replay of a previous authentication or synthetic video such as a deepfake).

Some types of biometric sensor require more specialized hardware than others. For example, face biometrics only require a device with a user-facing camera – which a large section of the population has access to given the momentous rise in smartphone usage. Other types, such as fingerprint biometrics, require specialist technology like fingerprint readers, which are only available to those with certain hardware or specific smartphone, tablet, or laptop models. 

That is why iProov uses the face for biometric verification and authentication. It only requires a user-facing camera and has been built with the user at the heart of our design principles. The end result is an inclusive, convenient, and easy-to-use process, which is highly secure. Additionally, the face is unique in the way that it can be verified against a government-issued identity document, (such as a passport or driver’s license), or a trusted online database.
