Trust Stamp has filed a patent application with the US Patent and Trademark Office for its biometric tokenization technology.
The company’s Stable IT2 system is designed to turn a subject’s face biometrics into a cryptographic token, which is then used for authentication. All subsequent authentication sessions revolve around comparisons of the cryptographic token, ensuring that the underlying biometric data is not shared, or even stored.
In a statement announcing the filing for USPTO: 63/611,799, Trust Stamp explained the binding process that is central to Stable IT2, which entails the combination of a cryptographic key with biometric data in order to produce “sketch and helper data that can be stored anywhere, including on edge wallets, mobile devices, or a distributed ledger.”
This refers to advanced privacy-preserving methods used in biometric authentication. The “sketch data” is a transformed version of the original biometric data (ie. a facial image), which retains essential features for identification but cannot be reverse-engineered to reveal the individual’s actual biometric information. The “helper data” assists in the verification process, ensuring accurate matching without compromising the original data’s security.
This approach enhances privacy and security by ensuring that the actual biometric data is neither exposed nor stored, thus protecting against potential data theft or misuse.
“This tokenized matching is not only secure but also highly efficient, providing quick and accurate identity verification,” says the company’s Chief Science Officer, Norman Poh.
Founded in 2016 in Atlanta, Georgia, Trust Stamp has gained prominence in the field of secure digital identity and authentication, leveraging artificial intelligence and advanced cryptographic techniques. The company’s rise to prominence is marked by its commitment to creating solutions that balance robust security with strict data privacy, catering to a growing global demand for secure yet user-friendly identity verification technologies. Trust Stamp achieved a Nasdaq listing near the start of 2022.
In recent months, the company has been in the news for its ‘alternatives to detention’ solutions, including a location-tracking wearable that is designed to look like consumer smartwatch.
