## Biometric Identity Verification

Biometric identity verification is a security technology that uses unique biological traits, such as facial geometry or fingerprints, to confirm a user's identity during the onboarding process. In digital asset trading, this is often combined with liveness detection to ensure that the person behind the screen is physically present and not using a spoofed image or video.

This technology provides a high level of assurance, significantly reducing the risk of identity theft and fraudulent account creation. By integrating biometrics, platforms can satisfy stringent Know Your Customer requirements while providing a frictionless experience for legitimate users.

The process involves capturing a live image, converting it into a digital template, and comparing it against government-issued identification documents. This adds a layer of physical-to-digital authentication that is difficult to bypass.

As security threats in the crypto space evolve, biometric verification has become a standard tool for protecting platforms and their users. It is a key component of modern digital trust architecture.
