More Details on How the Touch ID Fingerprint Sensor Works

The ring doesn't apply anything to the finger, it is just used as a "switch" to enable the sensor. The sensor then reads the fingerprint at that point.
But since the whole thing is capacitive, there's nothing really to focus. The frequencies for any RF being emitted by the capacitive grid are too low. Optical lenses can't focus them.
How so, and what do you propose as a better alternative? To me it seems every bit as secure as a pass word but more convenient, which probably will make more people use it.
So you have nothing specific in mind, well it's better than nothing I think we can agree on.
They can use your finger against your will, they can't use your password unless you give it to them.
I am getting a kick out of all the mugging, finger chopping scenarios. Most thefts are likely grab and run. And for those where getting into the phone is critical, my guess is putting a gun to someone's head and asking for the pass code (if not using the scanner), will likely work as well. The pass code is no more secure. Further, one can now lock up and wipe their phone, making it unsellable.
You have no clue how anything works do ya? Maybe you are being intentionally dense and I missed the "//s"

There are innumerable kinds of secrets. To name a few: a secret series of letters, numbers, and symbols, or perhaps a secret way of touching your phone, or a secret noise, etc. It doesn't really matter what it is (given that the device can sense it), so long as it requires knowledge only the user has.
Complicated procedures leads to simple pass words like 1234 or no pass word at all which we were told represented about half of the iPhones. A security measure needs to be adapted to what is protected, for example it makes no sense to spend $100 to protect $10.
I was thinking the same thing. I assume it is just a matter of time before this is added in.

Maybe it's a security issue, i.e. Apple don't trust third-party apps not to share that sensitive information. So what I think will happen is Apple will need to develop an API that lets third parties use the authentication mechanism without actually getting access to any of the fingerprint sensor data. But to develop that API takes time and will probably be a feature for iOS 8 (along with allowing iCloud Keychain access, though for that one maybe we'll see it in a point update). We know they were already rushing to finish iOS 7 as it is, pulling people off people from the OS X team, and trying to get the iPad version of iOS ready in time. Some speculated the iPad version would be delayed. So the best hypothesis is they didn't have time.
Extreme jealousy is a byproduct of fear and insecurity. The kind of jealousy that disrupts your life and the lives of the people you claim to love. We can't always feel confident and secure with our lives and loves. Life would be boring and predictable if we were. That's the last thing a couple needs after a few years of marriage. Let's face it, a lot of married couples stay together mainly for the sake of their children. At least that's what some studies have shown.
Pulse and heat detectors don't work when the finger is cold and the blood has withdrawn, anyway.
Instead, AuthenTec patented a couple of different spoof detectors. One is a skin impedance checker (still spoofable) and the other looks for too large a variation in overall variable detection parameters for the particular user.
It's 500 DPI, which is 250,000 antenna sensors per square inch. Edit: 500 DPI is the NIST and FBI standard for fingerprint capture and recognition.
By "3D", I think people were referring to the fact that it measures a bit below the skin surface. See diagram below.
That's what Apple's website says, but if it's an RF sensor, then the ring is almost certainly the transmitter, so of course touching it would trigger a response in the central sensor.
Something I didn't see mentioned is what happens if it cannot read your finger, or if you choose swipe to unlock. I would guess you can alternatively use your PIN.
If so, then the reader is just a convenience item, not a real security feature... and people can still goof up by using 1234 as a PIN

I don't think that is correct. Look at the original patents from AuthenTec.
Why would they have had to add a stainless steel ring to the phone if it was just a switch to tell the sensor to turn on? Makes zero sense.
This worries me. One day Apple will be forced to upload and send fingerprint data to our government to track citizens and terrorists.
And your password and Id for iCloud and a way to make sure you don't have time to change them before he does, assuming he even considers that you turned on activation lock.
If somebody chops off your finger, can they use it to unlock your iPhone?
That is not a joke but a serious question.
I have been involved with the development of enterprise fingerprint access scanners. Installations were mostly buildings or wings of buildings for restricted access. Demographically, a lot of there installations are in "developing" countries where they don't trust lower class individuals with keys be it mechanical or electronic. Many workers have sold keys they were given for more than the job they are working in the facility.
But yes, there have been situations where fingers have been cut off with sheers for unauthorized access to a facility. I don't know of any domestic US cases but it has happened in South American countries. Issue is that unless keep the finger refrigerated or frozen, the flesh undergoes necrosis where the fingerprint deforms and the minutiae point pattern does not match that of the living finger.
IMO, we are going to see less than expected adoption of this fingerprint access. Also, I'm sure some bastards will start-up urban legends about fingers cut off by attackers to access an iPhone. I'm not planning to use the fingerprint scanner at all and keep with the PIN codes.
Also, the solution that has a lot better approach is a Bluetooth 4.0 key fob like the Unikey Kevo and the Proximo. Let them rip off your iPhone. If they didn't get the fob elsewhere on you, can't get access.
Biometrics such as fingerprint scanning is a very double edged sword. The question to keep on asking is was your body intended to have that function?
You use a standard passcode if your job requires gloves.

Right now. Best to get the bugs out before they start creating profiles, letting other apps use it etc.

I would love to see stats on how many stolen phones are muggings versus grabbed out of hands, pickpockets, snatched off tables or out of cars
Good.....
thieves deterrent.....better than that?....A small electrical discharge when unauthorized people intends to access your iPhone.....

I'm hoping that thieves won't go to the extreme of finger chopping. After all, right now if your phone is password/code protected they usually just plug it into iTunes and reset. Why deal with the hassle of cutting off someone's finger?
On a potentially more realistic scenario - several years ago, I was involved in a skiing accident where I nearly destroyed my right hand. It was banadaged for nearly two months. I realize that one can put many fingerprints into the iPhone so that the left or right thumb, fingers, etc can be used. My question is this - suppose I run into a scenario where my fingerprint is not available. Like the bandage situation. Will there be a backup way to enter a password or pass code? I saw on the video that when in iTunes it said "scan fingerprint" but there was also an option to enter password. Will this be available for phone unlocking as well?
