T Stamp Inc (NASDAQ:IDAI, EURONEXT:AIID) (dba Trust Stamp) announced it was granted another provisional patent to add to its portfolio of AI-powered identity services.
The company was issued a patent titled "Semi-Supervised Or Unsupervised Biometric Person Recognition" by the US Patent and Trademark Offices, it said in a statement.
This latest provisional patent adds to the company's portfolio, which already includes eighteen utility patent issuances. Moreover, Trust Stamp currently has an additional fourteen patent applications awaiting consideration.
Trust Stamp’s chief science officer, Norman Poh, highlighted the distinction between traditional biometric systems' two phases—biometric enrollment and biometric authentication—where human characteristics like face, voice, iris, or fingerprints are employed for secure identification.
According to Poh, biometric enrollment involves linking biometric features to an individual's identity, while biometric authentication compares stored features with present ones. Poh introduces a novel biometric system that breaks from this conventional approach. This system continuously learns and blurs the line between enrollment and authentication, allowing every authentication to potentially unveil new identity insights.
Unlike supervised biometric systems with explicit enrollment phases, this innovation operates in a semi-supervised or completely unsupervised mode, marking a departure from established practices.
Poh called the innovation “extremely impactful.”
“Among many benefits, it can track the gradual changes in the appearance of individuals over time without requiring them to re-enroll. This alleviates the need to perform periodic re-enrolments wherever this technology is so implemented,” Poh said.
The company is already working with a major financial services client to carry out biometric deduplication, Poh added.
