implementation of a biometric entry-exit tracking system for all travelers to the United States,

CBP Data Privacy Standards
CBP has issued Privacy Impact Assessments (PIA) documenting each new phase of biometric
testing and deployment. The most recent PIA from November 2018 is a comprehensive
document describing how CBP promotes data privacy and appropriate data collection practices,
including:
• Opt-out provisions: U.S. citizens who do not wish to submit to facial photo capture
pursuant to these processes may request alternative processing, which typically involves
a manual review of their travel documents by a CBP officer (CBPO).
• Deletion of U.S. citizen photos: Once a match is made and notated in the appropriate
systems, U.S. citizens’ photos are retained for no more than 12 hours, then deleted. CBP
retains only a confirmation of the crossing and the associated biographic information.
No photos of U.S. citizens are retained under this process.
• Routine testing: CBP regularly tests its facial matching algorithms to ensure high
performance and maximize match rates while reducing the risk of false positives.
Throughout this process, CBP has designed the tests in order to assess whether the
process generates the same results across all demographics, including differences in skin
tones.
• Prohibitions on additional uses: CBP’s business requirements do not permit its private
sector partners to retain or share the photos captured at the boarding gate. CBP shares
the facial images of in-scope travelers within DHS, but does not share U.S citizens’
biometric data with any other external federal entity. CBP may share information with
federal, state, and local authorities for law enforcement, judicial proceedings,
congressional inquiries, audits, and other lawful purposes; CBP updates its notices for
any new uses.
• Notifications to travelers: CBP provides notice to travelers at the designated ports of
entry through both physical and either LED message boards or electronic signs as well as
verbal announcements in some cases to inform the public that CBP will be capturing the
photos for identity verification purposes, and that U.S. citizens may currently request
alternative processing from a CBPO, should they wish to opt-out of the biometric
process. In addition, CBP’s public notices notify travelers that CBP will retain the photos
in secure DHS IT systems, with the exception of photos of U.S. citizens, which are not
retained unless linked to an enforcement record. When CBP operates in conjunction
with approved partner organizations, the public is informed that the partner is collecting
the biometric data in coordination with CBP. Upon request, CBPOs provide individuals
with a tear sheet with Frequently Asked Questions (FAQ), opt-out procedures, and
additional information on the particular demonstration or program, including the legal
authority and purpose for inspection, the routine uses, and the consequences for failing
to provide information.
