Sony's New Personal Fingerprint Scanner 130
MelloDawg writes: "This article at SecurityWatch.com describes Sony's new fingerprint verfication device that fits in your wallet and uses public key infrastructure." Of course, if the prints are never transmitted and the scanner is personalized for each user, it seems like Sony'd like everyone to have his own scanner -- how convenient.

From the linked site: It contains USB drivers for Windows(R) 98 and 2000 and there is a serial cable available for use with Windows NT(R) systems.
Shouldn't be too much trouble to interface to Linux through the serial option for now (though it does load the system more than USB - and we'll have USB support soon enough.)
Also from the site: Sony is working with Entrust Technologies and I/O Software Inc., to allow them to develop specific software applications and is also actively looking to work with other software providers in the infosec field
It's unlikely that they will be providing open-sourced drivers at first (Sony haven't really "jumped on the open source bandwagon" yet) but with Linux becoming more popular all the time, it's likely that demand will convince them to build drivers.
They'll almost certainly be building drivers for various UN*X systems because, despite Microsoft's efforts to push NT, there are many large institutions which will pay megabucks to have a more secure way of authenticating users that just works! The weakest link in most security is the users themselves, and the pathetic passwords most people choose.
Fingerprint assisted password protection would be much stronger, and I doubt Sony will restrict themselves to a single OS manufacturer if they're getting so many companies to write drivers.

Veridicom's fingerprint scanner has a Linux driver (Score:1)
Their USB product is just a scanner. Think of it as a minature flat bed scanner that works on direct finger contact with a postage stamp size chip.
They have their own Linux driver and user-level program that writes PGM files. Looking at their protocol I was able to write a program that worked with Scyld's "Univeral bulk USB driver" in just a few hours, so it works with 2.2, and you don't even need special kernel level support beyond the standard add-on USB package.
The product that is comparable to the announced Sony product is the serial port version, with an internal matcher. One mode of operation is to download a few hundred bytes of encoded fingerprint info. The device returns e.g. "28 of 35 points match", which might be good enough for a gas purchase but not good enough to authorize a major funds transfer.
The claim is that these devices can detect living from dead tissue. I don't doubt that is true in controlled cases, but it's probably mostly PR when the device is set up to scan cold, dry finger and still work with warm, wet digits. Even so, it's easier to just kill someone and take their wallet than to cut off their fingers and leave them alive.

Annother important point when talking about biometrics is the fact that your finger doesn't change much.

What's to say that an unscrupulous organization won't record your fingerprint scan and replay it to other machines, or use it to create a prosthesis that can mimic your finger in any way that is important for the scanners (I think they determine live/deadness by the conductivity of the tissue, which is a measurement you would have)
These scanners could go a long way towards addressing this. Each user could have their own, trusted, scanner that merely unlocks a crypto key(s) on board that are actually used to authenticate. If the hardware was open enough so you could trust is this could be a very good thing.

No, the problem is that, if someone steals your device, it is very likely to be COVERED in your fingerprints - after all, you handle the damned thing. all they need do is use a child's fingerprint kit to lift one intact print on sticky-tape, transfer it to the sensor, and they have unlimited access to your key.

Since the average slashdot reader is more likely to read a topic up at the 3-5 level, those who have been modded down are not getting the attention they really deserve. And, if the topics are knocked down just because they are offtopic, it becomes even worse. How is one supposed to bring an issue to the attention of the community if there is no place to do so?

And what about people with no eyeballs? There are plenty of ways to identify someone biometrically. Perhaps a quick X-ray shot of someone's facial bone structure that would uniquely identify them? After all, you could lose finger or go blind, but you don't see many people walking around without facial bones. In the horrible event that yours were traumatically injured, you could go to an identity verification place and have the ID system recalibrated to your new facial structure.

Further, the unique user position required to operate the Glansprint Scanner affords an excellent opportunity for punitive actions to be automatically taken against an individual attempting to fraudulently gain access to the secured system. Repeated attempts to circumvent the Glansprint Scanner would therefore be rendered impossible.

The one thing I have seen that might be slightly secure is a card that you input a numeric key into. This generates a key that you use as the password. This password is basically a one-time pad key. Once you use it it cannot be used again. The password only stays visible for a few seconds, less than 30 seconds I believe. After that you have to input your passkey again.
Until there is a safe and accurate ability to verify a person passwords are about the best we will get. But even still passwords can be cracked or interigated out.
Biometrics (Score:1)
Biometrics as an authentication scheme has been in the literature as far back as the the 50s. The US Department of Defense has spent very large $DOLLARAMMOUNTS on the subject. Recently, thanks to Moore's Law, the processor power to actually implement some of these ideas have become generally availble. Additionally, it has long been recognized that a single token is insufficient for access authentication. Bought groceries on your debit card recently? You need the physical access to the card (finger, eye?) plus a Personal Identification Number (PIN). Two tokens. We may get to the point that three tokens are necessary, but I'd be suprised to see it in my lifetime.
From Sony I want two things: 1) A white paper dealing with exactly how what they are selling works, for peer review purposes. (Sony is all about selling a better solution, so explaining the base method should have zero impact. Speed counts.)
2) The asurrance that Sony and the entities that it sells its solution to will not violate the privacy of the individuals who end up using the technology proposed.
Oh well. New sound card. Life is good.

Prevents only casual attacks (Score:3)
This device (and most of biometrics) is a fraud and merely security through obscurity. Once someone figures out how the card works, then it should be fairly trivial to build a device which opens the card up and grabs your public and private keys.
With PGP and GPG, there's a passphrase to prevent having physical access to the device instantly revealing the private key. You can't really do this with fingerprints (or other biometrics) since the fingerprint cannot be used as a key. The digital image of your fingerprint varies from impression to impression so the device has to ask itself "is this close enough to Alice's finger?" instead of using it as a key.
Even if they could use the fingerprint as a key (perhaps some abstract description of the fingerprint which doesn't vary much), then all you need is a sample of the fingerprint which is fairly easy to obtain. It doesn't even need to be off a live finger - any tests in the device for heat or circulating blood can be bypassed since they can exist only as physical prevention mechanisms, not mathematical mechanisms.
The only really legitimate use of biometrics is if you have secured hardware with trusted guards (i.e., real people) watching that you don't mess with the hardware and that you really are presenting your actual finger or retina. And even this shouldn't be trusted for very important things unless you have several guards at each machine, all resistant to bribes.
Biometrics on a card would prevent only very unsophisticated attacks from people unfamiliar with the cards. If your attackers won't have physical access to your card, then using PGP or GPG without a passphrase is just as secure and more convenient.

Seriously, though: for code-based systems (burglar alarms etc.) you can often have a `duress' code. If someone puts a gun to your head and tells you to shut off the alarm, you type that code. The alarm pretends to shut off - in reality, it calls the police, silently.
Better still, you could rotate a couple of code between being `valid' and `duress' - 2378 would genuinely shut the alarm off on Monday, Wednesday, Friday, while 7826 shuts it off on the other days. Enter one of these codes on the wrong day, it acts as a duress code.

Just like if you take two copies of PGP and compare them, you've got my secret key? The secret key is encrypted remember - the card doesn't know it. Only the card in conjunction with your (live) finger knows your secret key. If they've managed to steal your finger without you noticing, you have bigger problems than your ATM balance...
2) Someone steals your scanner which not only has your public key, but your private key as well, and you've lost your copy altogether.
Essentially a DoS attack... Yes, this would mean you'd have to revoke your old key pair and generate a new one. This will always be possible, though, unless you memorise your keypair and have total recall - or everyone stores their keys on a central server, so an administrator can give you another copy of your key. There's probably nothing to stop you having more than one of these cards, though (a bit tricky securely duplicating the keypair, but it could probably be done.)
The `attack' you describe would work perfectly well if this system were based on security through obscurity (CSS, anyone?). It isn't (I hope) - like PGP etc., it just relies on actually being secure. Perhaps we should patent idea that in case Microsoft try it? Nah - they'll just stick to FUD, lies and videotape ;-)

Re:Smartkey PGP? (Score:2)
> Lock the key, not with a passphrase, but with a unique hash from the biometric data;
You can't generate a consistent hash from a biometric - two readings will never be exactly the same and in cryptographic applications a single bit error will render the hash useless.
Instead, biometrics are compared by a pattern-matching engine that can tolerate some errors. This means that your private key will actually be stored in plaintext inside the token and you must rely on physical tamper-resistance to protect it.
> Only real problem would be if you damaged the fingerprint - and there is no reason why the key can't be stored ten times, one per digit.
The real problem is not a damaged fingerprint - it's a damaged or lost token. You must have some kind of recovery mechanism for this case and, naturally, it will also cover the less common case of an injured finger.

Depends on what you call a "casual attacker" (Score:2)
A quote from the article you are linking to:
"Biometrics are powerful and useful, but they are not keys. They are useful in situations where there is a trusted path from the reader to the verifier."
In this case there is a trusted path from the reader to the verifier because they are both inside the same tamper-resistant pacakge (no, not tamper-proof, there is no such thing).
"Trusted" is always a relative term and depends on the resources available to your opponent. If your opponent is a foreign government then even secure (breakable) hardware and (bribable, killable) guards may not be enough.
I don't know how many casual attackers have access to a focused ion beam workstation and the knowledge required to operate it and try to crack a multilayer tamper-resistant chip. See this article [cam.ac.uk] for more information about the techniques used to crack smartcards. Remember that this device is thicker and more expensive than a smartcard and could theoretically provide much better tamper resistance.
Correctly applied biometrics can let you have some security even when facing intentional misuse. I'd rather have access to my medical information protected by this kind of biometric token rather than a password that will end up on a post-it note on the secretary's monitor or a smartcard that will be "shared" because it is not tied to a specific person. Experience has shown that most people will bypass security in every imaginable way. Biometrics can help enfore an organization's security policy under these conditions.
Personally, I will stick to my passphrases (6 words, at least 2 of them not in any dictionary...)

However, what concerns me is whether or not this type of thing will be actually allowed for use by the U.S. government. Since everyone has his or her own unique fingerprint -- after all, the police use fingerprints to identify suspects -- that means there must be a lot of different factors and variables that go into a fingerprint. Doesn't that mean that a fingerprint has too many "bits" of information and couldn't be uploaded under current export restrictions?
It's sad to see the United States government is holding back technological progress by attempting to impose its own short-sighted laws on the rest of the world. I'd love to have a personal fingerprint scanner -- how about you, Bob Dole?
