A number of airlines, airport authorities and cruise lines may opt to leverage their own technology in partnership with CBP to facilitate identity verification. In compliance with CBP’s business requirements, these industry partners deploy their own camera operators and camera technologies meeting CBP’s technical specifications to capture facial images of travelers and use the Traveler Verification Service (TVS) facial comparison service for identity verification. Each camera must be connected to the TVS via a secure, encrypted connection. While the photo capture process may vary slightly according to the unique requirements of each participating airline, airport authority or cruise line, the IT infrastructure supporting the backend process remains the same.
Under the CBP partner process as implemented in CBP’s business requirements, CBP does not allow its approved partners to retain the photos they collect under this process for their own business purposes. These partners must immediately purge the photos following transmittal and identity verification through the TVS. Each CBP's partner's IT system must allow CBP to audit compliance with these requirements. 
 If approved partners elect to capture photos with their own cameras for their own business purposes under a separate process, these partners must provide a separate public notice, such as signage, which does not link that particular process to CBP.
