Delivering authentication to FIDO protocol from mobile devices

Digital identity and cybersecurity firm Queralt has been awarded by the United States Patent and Trademark Office (USPTO) with two new patents.

The patents describe a new, streamlined method for bridging trusted mobile digital identities with online registration and authentication.

Queralt developed the new technologies under the supervision and guidance of the U.S. Department of Homeland Security’s Cyber Security Division (CSD).

The efforts were aimed at addressing the lack of interoperability between CSD’s systems used to manage Personal Identity Verification (PIV) cards, and mobile authentication.

Queralt’s technology integrates Public Key Infrastructure (PKI) identity verification with FIDO authentication processes, which can include biometrics.

FIDO UAF authentication is made contingent upon the successful verification and validation of a derived credential, or x.509 certificate, which is stored on a mobile device.

In other words, Queralt’s solution binds the digital certificate of a specific identity document to the user’s account, enabling FIDO registration and authentication only if the identity is verified.

As a direct consequence of this, the identity trust established within the mobile device provides a strong assurance that the user is who they claim to be.

According to Queralt, the new patents come at a time when passwordless device authentication protocols are increasingly being deployed across a variety of industries.

“With increased global momentum in issuing trusted mobilized personal identities,” said Queralt’s Co-founder Michael Queralt, “the technology is well-positioned to bridge trusted digital identity, whether centralized or decentralized and its validation to the registration and authentication to online services in a private and secure manner.”
