Overview
Biometric data refers to the unique physical and behavioral characteristics that can be used to identify individuals, such as fingerprints, facial recognition, and voice patterns. This data is increasingly being used in various fields, including security, healthcare, and finance, with companies like Apple, Google, and Amazon investing heavily in biometric technologies. However, the use of biometric data also raises concerns about privacy and security, with experts like Edward Snowden and Bruce Schneier warning about the potential risks of mass surveillance and data breaches.
