This bill, titled the "Realigning Mobile Phone Biometrics for American Privacy Protection Act," aims to significantly restrict the Department of Homeland Security's use of specific facial recognition mobile applications. It mandates the Secretary of Homeland Security to develop standards within 30 days, prohibiting the use of apps like Mobile Fortify and Mobile Identify, or their successors, except for identification purposes strictly at ports of entry . The legislation further prohibits the Department from sharing these applications with any other federal, state, local, tribal, or territorial agencies, and requires their removal from most Department information technology, including remotely disabling them on non-Department IT. A key provision requires the immediate destruction of any biometric data, such as images or fingerprints, of United States citizens captured by these applications prior to the new standards' implementation, and mandates destruction within 12 hours for data collected at ports of entry.
