Who has your biometric information? Privacy vs Convenience

I understand your concern and I actually think at least being aware is a good idea. Fingerprints don’t bother me, and I have the TSA pre check, but we try not to use listening devices (Alexa, audio tv remote, etc) in our home. It’s not about paranoia, it’s an active choice not to freely give our information to data harvesters, who use it to target ads. They can pay me if they want that information. 

I have Global Entry. I didn't even think anything about the facial recognition or the fingerprints. It was worth it to me for the ease of re-entry.

While it would be extremely difficult to change your fingerprints permanently, they do change on a temporary basis at times due to illness or injury. If you had your prints taken during a time when you had a temporary change, your fingerprints would look different at a later date. They might still have enough points to match your "real" fingerprints, but not necessarily. Getting them updated periodically would catch any changes.

My mother has to get printed every so many years because she receives some state money as my disabled brother's caregiver. I think it's every five years. One year, they told her she had no prints! It's not uncommon for older people to have trouble getting prints due to changes in skin texture, but she actually had no ridges on two of her fingers. She had been doing a lot of cross-stitching that year for a huge standing nativity scene, and based on the way she held the rough cross-stitch fabric, she thought that might have been why those two fingers were missing their ridges--she had just worn them away.

Anyway, she had to go back six months later and get printed again, and this time she had fingerprints.

Who know that little old ladies who cross-stitch could look like criminals trying to evade the law LOL.

Same. We have global entry. I also had to be fingerprinted years ago for my teaching license.

I draw the line at DNA tests, though. I don’t worry much about government making me the enemy (though perhaps these days I should), but I do worry about our for-profit healthcare system excluding people or raising rates based on genetic predisposition to certain conditions. And I don’t really want any long lost relatives contacting me, either.

I don't think anyone has my fingerprints... the only thing I had face recognition / location services on was the timeclock app I used when we were working from home, because it HAD to be done like that.

I use location services for maps sometimes, but I try only to do that when I'm using the app. I don't like that my phone keeps tabs on me.

My job requires an iris scanner to get into a highly secure facility. I am enrolled in live scan as well, and I've been fingerprinted for my job. I am not concerned about it. I don't engage in any shady activities that would make me think my iris fingerprint or my actual fingerprints could be used against me.

You are wrong about the genetic testing. I hate that argument "I doubt anyone thought..." YES, some of us did think...and we decided to do it anyway.
I've said this before, if my DNA helps catch a relative who is a rapist or a murderer or a terrorist, then good. I'm all for it. Criminals deserve to be caught.
If I was that relative who submitted their DNA that got the Golden State Killer caught, I'd be ecstatic about it.

If they use my DNA and develop some new drug that helps people - good, I'm all for that too, and if the pharmaceutical industry make billions of dollars from it - I also don't care...because it isn't about the money, if at the end of that road there are real people who benefit, then that's what matters.
I can't do the research myself, I don't have the knowledge or skills to develop a new drug, or vaccine or cure for something, but if someone else can do it and my DNA is a part of that process, then I'm happy for that to happen, and no, I don't think I need (nor would I want) any of that money.

I will admit I skimmed through this thread because I have to go get dinner started... But, why would it be a problem for "the government" to have my fingerprints? I've had fingerprints taken when I joined the Peace Corps, and when I went to work at the State Department, and when I took a job with my county so I could work in the schools, and probably somewhere else along the way that I've forgotten. 

And if you have a driver's license, never mind a passport, then "the government" has all sorts of information about you.  

I've worked in insurance, banks and schools. They all gave my fingerprints. I use and depend of my phone, computer, gps and Alexa daily.

I am not overly concerned, there's no way to avoid it living a modern life.

I did genetic testing last year to look for cancer genes (thankfully everything came back negative!), and I was assured that data would remain protected. I have no desire to do a commercial test, where I pay to have my genetic material bought and sold to anyone with a big enough pocketbook. I also have no desire to discover any unknown relatives in my family - I have enough family drama as it is!

Lol, I didn't even know we could check that. Ours would be boring also. And I also had an argument with Alexa where I told her she was stupid since she couldn't find the music I was asking for.

I'm guessing its to make sure you are who your badge says. I could see someone who looks a lot like you steal your identity, and try to get away with impersonating you. If they had to give their fingerprints it would flag that they aren't the person who they are saying they are. So its not really making sure you are you but that someone isn't saying they are you. (hope that made sense)
