Huh. I guess they  do do things differently from Apple.

You missed the key part about Samsung pledging to cover any money stolen because of the fingerprint scanner. So swap phones with a friend. That's how easy it is.

Also for both the iPhone and this, that procedure is not ever going to happen in the wild, to create a fake fingerprint. It's hardly even hacking. It's putting up a copy to scan. Though these days everything even tangentially related to computers is called hacking by the media.

Simple way to protect your fingerprint from being captured from your phone screen and used against you.

Use a different finger for the scan than you do to normally touch the screen.  Pinky for the reader, index to text.

You mean one factor authentication where you leave said factor literally everywhere you touch isn't secure? Nawww.
 
2014-04-16 12:20:30 PM
I'd just as soon skip using the fingerprint reader altogether

Can''t Samsung come up with something new? Apple did it six months ago so they must copy it?

At least the S5's flaw won't have you driving off a cliff or into a lake.

Which is an uncharacteristically cool corporate move.

so his spoof is basically identical to what every single "spy" movie does to spoof the finger print scanners and has done for the last 30 years.??

seriously?  these finger print scanner people never thought to maybe try the stuff they use in movies?

FTFA: "For someone who has medium-resolution pictures of their fingerprints in databases around the world (or even pre-made spoofs lying around the office) like I do, the attack is already very practical"

Why would you do this??
 
2014-04-16 12:47:28 PM
Anyone that links only a fingerprint to an important online account is an idiot. That the device even allows this is going to cost Samsung a lot of money. I'm ok with that.
 
2014-04-16 12:48:57 PM
I love how this is supposed to be "easier" to hack then the drawing from dot to dot authentication.

I think I know all my friends Androids drawing authentication "codes", and I don't even try. You can shoulder surf it about a mile away. Would be much easier than to get someones fingerprint.
 
2014-04-16 12:51:24 PM
I think this is why Apple didn't allow third parties to connect to the fingerprint authentication. Because even if you unlock the phone you still can't use that to use apps that authenticate you separately.

BizarreMan: Use a different finger for the scan than you do to normally touch the screen. Pinky for the reader, index to text.


Pinkys don't often contain enough of an individual print to be able to use, which is why a lot of fingerprint software (including ones on laptops) have you do every finger *but* the pinky.

Replay attacks are a common weakness in ALL biometric identification techniques. If the device taking the reading is not physically secured against the attacker, replay is inevitable.

Regardless of who made it, if you're going to use your phone to access your bank information, you better treat your phone like a device that you use to access your bank information.

That said, using something as easily disregarded or lost as a mobile phone to satisfy inherence in authentication schemes is just plain stupid.

It's fun watching the open source zealots respond by arguing that open source protects us from stuff like Heartbleed...when it's what led to Heartbleed. It's like arguing with religious nuts...
 
2014-04-16 01:06:12 PM
Article i read said they used the same thing on the Apple phone and it works the same which isn't suprising.  Everyone remember the Mythbusters episode where they used these sensors and even a copier printout of a fingerprint worked.  Not sure why everyones all over fingerprint crap now.

Well you can do it differently. Apple only uses it to unlock your phone. This article suggests that other apps use it for authentication. (maybe that's not right but that's what it makes it sound like.)

Well since the source is open, it allows all sorts of things to wander in. I left my kitchen windows open once, and in the morning I had all sorts of bugs!

And you don't have to use it for banking if you don't want the option is there.  If you are worried this could happen to you then don't set it up.  I mean some super secret spy might lift a trace fingerprint then make a mold of your finger to steal the $50 in your paypal account that paypal/samsung will give you right back.

I would pefer fingerprint login for other apps over username/password.  I'm not tinfoil on head worried about this hack.

Open source means you have a lot of people looking over the code so that people can find flaws and fix them not exploit them, duh.

This is why you use two-factor authentication for financial accounts. How fast do you really need access to these things?

Well I was explaining to you only that it might be the same technology but the implementation is different. So it's not the same, like you said. I said nothing about which is better or what you may prefer.

geez relax.

What bugs me is you can't turn off the display of failed attempts. It shows clearly the failed swipe pattern and makes it easier to then guess the real pattern IMHO.
Why can't I turn it off? What is the point of showing me my failed attempt?

So what stops people from looking at the code looking for exploits and not reporting them like was done with Heartbleed?

You know that did happen right?

If someone drove off a cliff, or into a lake because of a map flaw in an iPhone, then Apple did a favor for us and removed them from the gene pool.

CSB:

I was deploying a new a new Dell laptop with a fingerprint scanner to one of our executives, and was
explaining how to work it, and she got this evil grin on her face.

"You mean I can use any finger?"

"Yes, ma'am."

I think y'all can guess which finger she decided to register.

As to alternative biometrics, we could have ear scanners, or go the PARANOIA route and tattoo
everyone's tongues at birth.
