Having worked for a company that used the fingerprint technology in its security system, I managed a look under the hood, so to speak. For the technology to work, a live finger with a blood flow is required. The readers measure the blood flow pattern just under the surface of the skin as masked by the spirals and whorls in your print. A 3D copy of your finger just isn't up to the job.
Besides, if you are concerned about using a cell phone with fingerprint security, get something else.
The difficult may take time, the impossible a little longer.

First paranoia is a survival skill.
Second techies wanting to make a fast buck could develop systems to make and customize the gloves to sell to criminals.
Lastly I work for the government and evil intent is not the problem. It is the ineptitude of managers that sets us up for such major disasters as the OPM hack. Your finger prints are now in the hands of criminals and foreign agents.

25 years of federal law enforcement made me understand that if you think someone is out to get you, you are more often right than wrong.
I have next to no knowledge of 3D printing. I will be very surprised though if someone doesn't do a finger print hack soon.

See, I think that very lack of evidence that hackers are exploiting fingerprint scans demonstrates that they are indeed not being sent to the CIA/NSA/IRS, etc. Because, you know, zero day.

What a great idea!..but probably not. On a related note, I've just looked up an IP that was trying to hack my FTP server last night and it resolves back to northern Virginia! Hmmm....

You are not paranoid if it is true...

What you should be really paranoid about is what information is being sent back to the maker of your cellphone and your data provider.
It's already been shown they're tracking users and collecting the data.
At least NSA/CIA (for the present, at least) don't consider everything about you a marketable commodity. They actually like to keep that stuff to themselves.
And if whatever it is was made in china - well, you know what they say "Abandon ye all hope who enter".
So - much as you were about spy agencies, I think your paranoid episodes should be spent worrying about big businesses.

What finger are you sending to the NSA?
Just curious...

If they haven't already thought of doing it, you've just given them the idea.

Just cause you're not paranoid doesn't mean they're not after you.

I'm not sure why I would care.
Someone else having an image of my fingerprint doesn't open my bank account. Doesn't authorize my credit card.
I can't think of anything for which my fingerprint image is used.

As opposed to what "they" already know (or could find out) about you from your financial transactions, online presence (facebook, linkedin, twitter, CP postings... etc.), phone records, texts, tax returns, voter registration records, school transcripts, ad infinitum.
I ask you, what further erosion of privacy could having your fingerprint (or iris scan, or hand geometry, or palm print, or voice pattern, or face image) possibly amount to?

Fingerprint scanners on phones and keyboards don't take very good fingerprints. they are good enough to distinguish between the phone owner and a random sample most of the time. That's all they have to do.
If the NSA wants your prints, they just send the FBI (because NSA doesn't have field offices within the United States) to break into your home or car or office without a warrant and take 'em. Warrants are for wimps. They can always fake up probable cause later to get new prints for the forensic record.

Better question.... Why would Apple/Google/Microsoft engage in an activity that, if discovered, would severely damage their credibility, lead to multi-million dollar lawsuits, and possibly result in some executives going to jail --- all for the benefit of some third-party organization? How would they keep the 100s is developers/QA testers/executives quiet about an obviously illegal activity? How would they keep the transmission of the data secret for the hackers and security pros carefully monitoring every package transmitted, looking for flaws?
Truth,

Even better:
Hackers have already learned how to harvest your fingerprint from your cell phone or tablet if it has fingerprint recognition installed. even if you don't use it.
If someone steal your password you can get another. But you can't get new fingerprints.

BS. That Chaos Club so-called "hack" is in practical terms nonsense. Because it's completely impractical to perform the "hack" for a random person. The "hack" required physical access to the phone itself.
You leave your fingerprints EVERYWHERE. I don't need to steal them off your phone if I REALLY REALLY want them. Like off the glass of your phone, for example.

wow. thanks for the kindly curse words
one notes how often its possible to access other devices on your android without physical acccess. Matter of time.

No. I work in the fingerprint sensor industry. I'm not aware of any such program. It would undermine people's faith in the integrity of the system. Plus data is usually encrypted when stored or transmitted anyways.

Of course.... they also send them to the Illuminati, the Priori of Sion (formed by those darn Elders), the Super Saiyan and to a special account of the Guardians of the Galaxy.
This all happens in real time. No wonder it takes so much time to actually log in using Touch Id.

They don't need to send data to the NSA, the NSA can simply hack their servers and steal it.
