T Stamp Inc (NASDAQ:IDAI, EURONEXT:AIID), doing business as Trust Stamp, announced that the United States Patent and Trademark Office has allowed its patent application for the "Interoperable Biometric Representation" framework, an innovation that enhances privacy and security while addressing a major challenge in biometric interoperability.
“This patent not only resolves interoperability issues but also operates within a privacy-preserving, tokenized domain,” Trust Stamp chief science officer Dr Norman Poh said.
“These privacy-secured IT2 tokens allow users to obtain and compare biometric data from multiple sources without risking vendor lock-in, a problem that has long plagued the industry and hurt customers.”
Biometric identification and verification are widely used, but differences in proprietary data formats prevent seamless compatibility across systems, limiting adoption and locking users into specific vendors, the company noted in a statement.
Trust Stamp's framework overcomes this by converting biometric data into a universal, privacy-secured format, enabling recognition and validation across platforms without requiring changes to existing vendor processes.
The system also integrates Privacy Enhancing Technology (PET) through its irreversibly transformed identity tokens (IT2), allowing biometric matching without storing or exposing sensitive data.
Facial biometrics gap
Scott Francis, Trust Stamp chief technology officer, highlighted the significance of the technology.
“Interoperability in facial biometrics is non-existent today, and this patent addresses that gap,” Francis said.
“First, it allows biometric samples from different vendors to be compared by converting their templates into a common format.
"Second, it provides an open-format/open-weight neural network solution that approved vendors can use directly to generate face templates that are compliant with the format, eliminating the need for proprietary conversions.”
