I’ve been compiling a list (April 2 update here) of PAD 3 conforming solutions, or biometric solutions (so far only face) that satisfy a high level of presentation attack detection (liveness detection). This satisfaction is determined by independent testing bodies such as BixeLab, iBeta, Ingenium, and Tüvit.
While nosing around, I found one other entity that performs these assessments: the Swiss Biometrics Center of the Idiap Research Institute.
The SBC’s attestation letters can be found here, including PAD Level A and PAD Level B conformance letters for entities such as Mobai and Identy.
No PAD Level C attestation letters yet.
