An anonymous reader shares a report: Immigration and Customs Enforcement (ICE) does not let people decline to be scanned by its new facial recognition app, which the agency uses to verify a person's identity and their immigration status, according to an internal Department of Homeland Security (DHS) document obtained by 404 Media. The document also says any face photos taken by the app, called Mobile Fortify, will be stored for 15 years, including those of U.S. citizens. The document provides new details about the technology behind Mobile Fortify, how the data it collects is processed and stored, and DHS's rationale for using it. On Wednesday 404 Media reported that both ICE and Customs and Border Protection (CBP) are scanning peoples' faces in the streets to verify citizenship. "ICE does not provide the opportunity for individuals to decline or consent to the collection and use of biometric data/photograph collection," the document, called a Privacy Threshold Analysis (PTA), says. A PTA is a document that DHS creates in the process of deploying new technology or updating existing capabilities. It is supposed to be used by DHS's internal privacy offices to determine and describe the privacy risks of a certain piece of tech. "CBP and ICE Privacy are jointly submitting this new mobile app PTA for the ICE Mobile Fortify Mobile App (Mobile Fortify app), a mobile application developed by CBP and made accessible to ICE agents and officers operating in the field," the document, dated February, reads. 404 Media obtained the document (which you can see here) via a Freedom of Information Act (FOIA) request with CBP.Read more of this story at Slashdot.
