T Stamp Inc (NASDAQ:IDAI, EURONEXT:AIID), doing business as Trust Stamp, has received a Notice of Allowance for an additional patent by the United States Patent and Trademark Office (USPTO) related to its AI-powered, tokenized-identity products, the company announced.
The patent, titled “Systems and processes for lossy biometric representation," expands the IP protection around the company’s biometric hashing technology used for subject identity verification.
The technology uses neural network processing and pseudorandom matrix multiplication to generate anonymized vector representations of biometrics that can be compared to one another for verifying a subject’s identity.
The anonymized vector representations are considered “lossy,” meaning not all information from the original biometric is included in the anonymized vector representation. Generating lossy representations allows for enhanced security when dealing with a subject’s sensitive biometric data, while still allowing for the anonymized vector representations to be compared to one another with a degree of certainty high enough for identity verification, the company said.
This latest notice follows a similar USPTO Notice of Allowance received in April that covered three patent applications, the company said.
“This latest Notice of Allowance marks an important win and significantly enhances the IP around our AI-based authentication technology,” chief science officer Norman Poh said in a statement. “With over 30 patents now issued, allowed, or pending, over the last seven years our team has developed a highly defensible IP position that is now being productized across an ever-growing range of use cases.”
Trust Stamp has integrated the identity verification processes from this patent into its Irreversibly Transformed Identity Token (IT2) technology, which uses AI to generate an identity token rather than relying on biometric templates. The token cannot be reverse-transformed to recover the original data.
“The IT2 represents an evolution of biometric authentication that provides the subject with an exceptional level of security, while greatly enhancing the utility of the original biometric capture,” Poh said. “These capabilities have clearly differentiated Trust Stamp in the market, and industry feedback has been extremely positive, resulting in a rapidly growing commercial sales pipeline.”
