Trust Stamp Announces Notice of Allowance for New U.S. Patent Related to its Artificial Intelligence (AI) Based Biometric Authentication Technology

Trust Stamp the Privacy-First Identity Company providing AI-powered trust and identity services used globally across multiple sectors, announced that it has received a Notice of Allowance for an additional patent by the United States Patent and Trademark Office related to its AI-powered, tokenized-identity products.  This Notice of Allowance follows three additional patent applications announced.

The patent, titled: “Systems and processes for lossy biometric representation,” expands the IP protection around the Company’s innovative biometric hashing technology used for subject identity verification.  Through neural network processing and pseudorandom matrix multiplication, the technology in the patent generates anonymized vector representations of biometrics that can be compared to one another for verifying a subject’s identity.  These anonymized vector representations are “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.

Trust Stamp has integrated the identity verification processes from this patent into its Irreversibly Transformed Identity Token technology – a privacy-first solution that replaces the storage and use of biometric templates with an irreversibly transformed identity token, or IT², generated by AI.  The use of AI allows Trust Stamp to provide users with the benefits of biometric-derived authentication without losing control of or sharing their original biometric data.  The IT cannot be reverse-transformed to recover the original data and thus offers a privacy-protecting methodology to enjoy the benefits of biometric-based authentication without the dangers of storing biometric templates.

Dr. Norman Poh, Trust Stamp’s Chief Science Officer, commented, “This latest Notice of Allowance marks an important win and significantly enhances the IP around our AI-based authentication technology.  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. 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.  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.”
