Regarding biometric data, it is just data. Given that various actors have undeniable access to all data that is possible to be stored on every computer, since all commercially available chipsets are compromised at the factory, I strongly urge folks to ensure that such biometric data they control is not provided to those actors.

Chrome is designed to funnel data to Goolag. Goolag wants a monopoly on that data, and Chrome therefore impedes other actors, but Goolag having your data is probably worse than almost any other malicious actor gaining it, due to Goolag's technical competence and influence over government and other institutions.

There simply isn't such a thing as a secure computer. It's just ones and zeroes, and competent code is able to affect digitial systems through every I/O channel. Some actors can be excluded by cryptographic means, but script kiddies aren't the greatest threat extant to victims of compromised computers. State actors, extranational corporations, and similar institutions bear far greater, even existential risks, to such victims.

Lights shone on external LEDs on computers, on the vehicle lights of cars with onboard computers, sounds played into speakers, DNA scanned by computers used to automate the process of gel electrophoresis, and every other I/O channel potential to computers have provably been shown to be effective vectors for malicious software.

A bad actor can use your biometric information when it is acquired in many ways, and if that actor is compromised, they can simply abandon that identity and move on. You can't. You are trapped by your biometric data. You can't abandon it or alter it.

Don't make it available to bad actors if you can prevent it.

Thanks!
