MojoKid writes "Consumer and business-class computer security has clearly become more sophisticated over the years.
Recent advances in recognition technology have brought forth new capabilities, like what can be found in Toshiba A305 series notebooks. Toshiba's Face Recognition software allows you to log in to the system simply by having your face properly recognized by the integrated webcam during Windows startup. Of course, the system's TrueSuite Access Manager also allows you to do the same, only using your fingers and the integrated fingerprint reader. However, TrueSuite goes a step further with the fingerprint reader, also allowing you to log in to Web sites, applications, and networks as well by using just your fingerprints."

Otherwise, if the "bad guys" have access to your machine, you're Pwn3d. Demos have been done using pictures of people to fool facial recognition software.
Of course, if an owner has cosmetic surgery or a really nasty accident, it's the owner who'll get locked out of the machine. If they want to use biometric ID for anything but security theater, they need it as part of at least two-factor authentication. . . meaning "something you know" (i.e., a password) or something you've got (e.g. an RFID token key)

It'd be great to have computers with stereo vision... With so many computers now coming standard with pinhole webcams, surely they don't cost too much. You could place one webcam at each top corner of the screen and then the computer would be able to produce a 3-D image of its environment.
Now you have to get a 3-D model of the person's face instead of just a photo.
This whole thing could be really bad. Imagine someone that just underwent massive facial trauma. Now, not even their computer likes them.

Yes and no. For someone buying a laptop and then making regular use of this technology, it's absurd, or at least little more than a toy when viwed from a security perspective. On the other, we all seem to be heading to a future where computers are, or least behave, in a more personal manner, so in that sense, this technology is, for lack of a better word, a really cool idea.
Then, consider that the world around around us is demanding increased security and is thus subject to increased surveillance and control. That's true from the CCTV cameras monitored by law enforcement, to the folks at your local DMV or voting precinct trying to prevent fraud, to the liquor store owner checking his store while he's at home. It's a fair assumption that with increasing interest in these technologies, we'll see a corresponding increases in research and development, which will, in the end, lead to widespread usage of whatever technology wins out, whether that's iris scans, fingerprints. forearm barcode tatoos, DNA, faces, or a combination of any of the above. If you took a vote on which approach people want, I doubt anyone would say "It's more passwords and PINs for me!".
If it becomes possible to replace every lock and key with some sort of recognition software, would you complain, or tout all the benefits? Or if you could save tax dollars by replacing local security on the streets and Home Depots everywhere with similar software, would you view that a good or bad idea?
Let's face it, the above scenarios aren't very likely, at least in the short term. We're still working on voice recognition. For now, however, it doesn't mean we can't have fun playing with Toshiba laptops.

Biometric ID has it's bad points, and certainly, in the most secure settings, you'll probably want to make sure you have contingencies for these. But these are not notebooks designed for the FBI, they are designed for the security conscious business user.
With that in mind, suppose, today, that a criminal was sitting before you with a knife, threatening to cut off your fingers one by one if you did not give him your notebook password. Are you really willing to sit there and tell me that you would rather have your hands butchered than give up your text-based password?
If someone was really willing to go to lengths like cutting your fingers off, then they probably have all sorts of incentive to do all sorts of awful things. I'm not sure Biometric security appreciably changes the situation for 99.9% of users.

That's where plausible deniability tech comes in. You'd give the criminal an alternative password which works but decrypts a dummy disk instead.
Though, the same technique could work for fingerprints. One finger gives you the real files, another gives you the dummy. Though testing for this isn't that hardm as there are only 10 to check.

That's the problem. People believe that these things are secure enough for the security conscious business user. Laptops are stolen all the time, whether for corporate espionage purposes or for resell value. The thing most people don't realize is that you don't have to cut someone's finger off to use their fingerprint on common scanners. There are many ways (the gummy bear technique) to fake a person's finger and print for these cheap fingerprint scanners.

It's not a realistic scenario; if you were sitting beside a criminal then they could just force you to put your fingers onto the finger print reader (no amputation required). In general, a criminal would not even need your actual fingers, but just your finger prints.
I would suppose that the computer algorithm would probably just need the md5 hash of the finger prints.

Well, you obviously base your argument on false presumption that a criminal has immediate access to you and the notebook at the same time, same place.
However, if this is not true (e.g. they stole the notebook first and hidden somewhere, then discovered the need for the fingerprint and got to you - the owner), they are very likely to cut off your finger whether you're willing to cooperate or not. It's simply so much easier to move around the city with a cut off finger than with a kidnapped person (or corps

It is important to note that both fingerprint and face-recognition technologies are not foolproof--there are a number of known, low-tech means of circumventing them. As such, depending on how secure access to your system, data, and Web sites needs to be, you might want to think twice before relying on these alternatives to typewritten passwords.
Right! Such as presenting it with a photo of the owner. Or using one of several well-known techniques to lift a fingerprint from somewhere (the computer itself?) and create a fake finger.
Why isn't this kind of "security" generally laughed at by the consumers?

Exactly. This is crap. The sooner that people learn that biometrics are largely unique, but rarely private (I can take a picture of you in the street, or lift your fingerprint from anything you touch), the sooner we'll stop trying to build security systems around it.
Add to that the whole non-revocation of credentials bit inherent in biometrics, and suddenly smart cards and passwords seem a whole lot more practical. Guess they're just not sexy enough any more.

Thinkpads have done this for at least two years already. The password manager app even has a plugin for Firefox. Mind you, I disabled it almost immediately because it adds an addition, out-of-place "Save this password?" prompt to every ever remotely passwordy prompt in Windows, IE, or Firefox.
But the functionality is there, and has been for some time. I hope these TrueSuite guys don't genuinely think they've got something new.

Rubbish. Without full disk encryption, laptops today are as vulnerable as they were 15 years ago. If anything they're *more* vulnerable nowadays, simply because we store more on them, keep them connected to the net all the time, and more people are using them.
Gimmicks like fingerprint readers and face recognition are worthless if someone steals your machine. Simply boot knoppix, mount the fat/ntfs partition and copy all that juicy data right off the drive. In fact this happened to a high-profile person recently - someone recovered Adrian Sutil's (F1 driver) discarded hard disk and tried to get money off him in exchange for not publishing his photos and emails.
Face recognition is probably good fun to try out in the store and maybe help sell a few machines. But disk encryption and strong passphrases are inconvenient and require a bit of work, so nobody uses it.
