Data 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.
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.
