Through a Freedom of Information Act lawsuit, EPIC has obtained a report from Custom and Border Protection, which evaluated iris imaging and facial recognition scans for border control. The "Southwest Border Pedestrian Field Test" reveals that the agency program does not perform operational matching at a "satisfactory" level. In a statement to Congress earlier this year, EPIC warned that biometric identification techniques are unreliable and lack proper privacy safeguards. EPIC is pursuing related documents for the use of biometrics at airports. EPIC has extensively litigated airport screening techniques, including EPIC v. TSA (concerning body scanner modifications) and EPIC v. DHS (concerning full body scanner radiation risks).
