San Francisco has passed the first facial recognition ban by a major U.S. city. But tech firms and businesses are beginning to fight back against laws that could restrict biometric authentication.

The release of the guide comes in advance of the Securing Federal Identity 2019 conference and is designed to distill findings from a NIST special publication on the use of PIV for physical access control in the government enterprise.

The iPhone maker recently has moved to facial recognition technology, following larger trends, but the new patent seems to indicate other biometric authentication possibilities, including a possible renewed focus on fingerprint.

The prestigious industry recognition takes place in June at the 2019 SIA GovSummit in Washington, D.C. The Women in Biometrics Awards, now in its fifth year, is accepting nominations for the 2019 program through June 1.

The facial recognition technology from IDEMIA beat out a large group of other vendors’ technology in a recent NIST trial— and the win comes as biometrics take more of a role in all facets of authentication.

One of the most expensive and cumbersome parts of a secure ID implementation is the proofing of employees prior to credential issuance. For government credentials issued by federal agencies and contractors, the identity proofing process can now be managed remotely rather than via in-person interviews.
