Worldcoin saga turns spotlight on Kenya's data privacy challenges

Biometrics is a way to identify people using unique physical traits. It involves technology that can recognise things like fingerprints, face shape, voice, or even how someone walks. This technology is often used for security, like unlocking phones with a fingerprint or face, or at airports to confirm someone's identity.
