Researchers ranked 96 countries by their collection and use of biometric data. 

Biometrics are gathered and stored as part of international travel, banking, law enforcement, healthcare tracking, and general surveillance by governments.

The worst offenders from a privacy perspective were:

1. China
2. Costa Rica
3. Iran
4. United States, Uganda, United Arab Emirates, Bangladesh, Philippines, and Saudi Arabia (a 6-way tie for 4th place)

The danger with biometrics is that once any government or entity has them, they might be able to track your activities for the rest of your life. Biometric markers are chosen for accuracy and longevity. There is no reset or reissuance. 

If a cybercriminal obtains it, they may attempt to impersonate you or validate transactions with your identity! Privacy matters.

Stay safe online.
