What ethical concern does "biometric data" raise?

The ethical concern that biometric data raises primarily revolves around the potential for identifying individuals without their consent. Biometric data includes unique physical characteristics such as fingerprints, facial recognition, and iris scans, which can be used to identify individuals in a variety of contexts. The use of such sensitive information often occurs without the individual's explicit permission, leading to significant privacy issues.

This lack of consent is particularly troubling because individuals may not be aware that their biometric data is being collected or how it will be used, stored, or shared. This raises questions about autonomy, privacy rights, and the potential for misuse of such data, making it a pressing ethical issue in the broader discussion about data privacy and security.

Other options present concerns related to biometric data as well, such as storage challenges or accuracy issues, but the core ethical dilemma hinges on the violation of consent and personal privacy.
