Biometric data collection refers to the process of gathering unique physical or behavioral characteristics from individuals for the purpose of identification and authentication. This method leverages traits such as fingerprints, facial recognition, iris patterns, or voice patterns to create a digital representation of a person, allowing for secure access to systems and information. The use of biometric data collection is gaining traction in various fields, including security, marketing, and healthcare, due to its potential to enhance data security and streamline user interactions.
