In comments to the Transportation Security Administration, EPIC urged the agency to consider alternatives to expanding the collection of biometric identifiers for the TSA Pre-Check application. EPIC explained the potential for biometric identifiers to be used for purposes other than determining eligibility for Pre-Check and the substantial personal privacy risks for applicants if the databases associated with Pre-Check were compromised. EPIC also proposed privacy enhancing alternatives, such as limiting the storage of biometric identifiers or providing information on how to have information removed from databases associated with Pre-Check. EPIC routinely highlights the risks of large, overbroad government databases and the privacy risks inherent in the collection of biometric information.
