Biometric data definition

Biometric data is information about a person that can be used to identify them based on their unique physical features. There are many unique identifiers, but facial features, fingerprints, and voice are most often used for identifying someone.

Biometric data use cases

  • Everyday authentication. Our smartphones use our facial features and fingerprints to identify us for anything from unlocking the device to making a payment.
  • Physical access. Some offices, gyms, and other members-only institutions use fingerprint scanners to identify a person and grant them access.
  • Law enforcement. Government agencies use surveillance cameras and face recognition technology to track criminals and suspects. In some countries, it is also used for tracking and monitoring regular people.

Biometric data protection

A person can’t do much to protect their biometric data other than being very mindful of who they trust their information with. It’s important to make sure the companies you give your biometric data to have strong security measures in place to fend off cybercriminals and prevent data leaks. Your fingerprint is not a password and can't be easily changed. While it’s a great way to secure your banking account, consider using a PIN number or a regular password for your social media accounts.
