The Homeland Security Presidential Directive HSPD-12 called for new standards to be adopted governing the interoperable use of identity credentials to allow physical and logical access to Federal government locations and systems. The Personal Identity Verification (PIV) standard for Federal Employees and Contractors, Federal Information Processing Standard (FIPS 201), was developed to establish standards for identity credentials. It describes technical acquisition and formatting specifications for the biometric credentials of the PIV system, including the PIV Card1 itself. It enumerates procedures and formats for fingerprints and facial images by restricting values and practices included generically in published biometric standards.
