A Notice of Proposed Rulemaking has been published by the Department of Homeland Security authorizing a significant increase in biometric information that U.S. Citizenship and Immigration Services, Customs and Border Protection and Immigration and Customs Enforcement would be able to collect.
The government redefines biometric to include behavioral characteristics along with biological characteristic that can be used to identify someone. And it outlines new types of biometrics that they plan to authorize themselves to collect.
