If you are new to the identity space, this is where you will want to be in June (for some definition of “be”). This year I am going to block the entire agenda in my calendar months in advance,so I can spend more time in whatever social contexts the universe will allow!

We must put the control of critical risks — privacy, accessibility, inclusion, and diversity — at the center of our attention. These risks are too often left as afterthoughts in biometric identity systems. 7th in a series for TBW '21 https://t.co/FMFDdwtIKS

DNA is far more accurate than any other biometric modality, including conventional fingerprints, facial recognition, iris scans, and voice recognition. But the risks are high (and complex) regarding privacy and consent. 6th in a series for TBW '21 https://t.co/zZpiSCbpKy

Voice recognition is the exercise of matching a specific speaker’s voice to a unique digital representation as a means of identity authentication. But voice is a combination of physiological and behavioral biometrics. 5th in series for TBW '21 https://t.co/8vSFOOMgbB

The iris is considered to be the most reliable ocular biometric trait. Iris images are typically acquired using sensors that operate in the near-infrared (NIR) spectrum. 4th in series for TBW '21 https://t.co/wSljXp4n5K
