Can I ask what country?

I have put some thought into behavioral biometrics and I think they are a futile path. (Maybe still interesting to study though.) Behavioral metrics are an irrivocable, unhidable key that requires invasive surveillance to read. Verification is an arms race that wastes resources where only tyrants and sophisticated criminals win, while users and system integrity are collatoral damage. I am afraid this approach will be popular for exactly these reasons, however. You might be able to do valuable work exposing these flaws, though I am not sure how well that would go for your academic career.

for data leak risk sake, it sucks bad, like not as bad as genome sequence leak bad, but still for businesses and data exchanges, this is just sensors that already gather this data, which is not being taken advantage of and not being turned into profit at the end of the day, you are nothing more than a convertable data asset that can be converted to money
