Disney World Collecting Fingerprints
cvd6262 writes "Disney World is now requiring all visitors to have their index and middle fingers scanned to gain entrance to the park. This started for season pass holders, but is now required for everyone." From the article: "'I think it's a step in the wrong direction,' Civil Liberties Union spokesman George Crossley said. 'I think it is a step toward collection of personal information on people regardless of what Disney says.'"
With that aside, WHO CARES. You cannot be uniquely identified by your hand geometry, it simply reduces the chance that you are using someone elses pass.
Seems like I go through this every time a biometric security thing comes up on /.
There are three fundimental ways to identify yourself for access:
Something you have.
Something you know.
Something you are.
Something you have would be a physical token that can't be copied, at least not easily. A smartcard would be a good example. Someone has to physically steal it from you to use it, and you are likely to notice it's absence and alert the proper people. However the problem is that it can be stolen, or lost and thus used.
Something you know would be a password or PIN code. It's an ID stored in your head. The advantage is you don't have to carry it around and can't lose it. The problem is if someone finds it out, they can use it without you ever knowing it's been compramised.
Something you are is of course a physical trait. The good thing is that can't be stolen or anything. Problem is what you are changes, and can't be measured precisely anyhow and thus can be spoofed.
Now, real security comes from using 2 or three of these. Since their problems are different, moving to more than one makes it much harder to compramise security. If all that is required to get on a system is a password, all an intruder needs to do is find out the password and they are in. If, however, it takes a password, smart card, and fingerprint they have to find out the password, steal the card, and obtain and make a fake finger, all before any of this is noticed and access can be revoked.
So, in the case of Disneyland, they are maoving from 1-factor (somthing you have) to 2 (something you have and something you are). Even if someone steals your card, they have to build a fake hand (it's checking hand geometry, not fingerprints) and use it unnoticed. However the real aim is to prevent peopel from shaing their cards. It's easy to give away a token, much harder to make a convincing fake hand and not get caught.
So biometrics are NOT worthless unless they are the only security. When used as an augmentation to one or both of the other methods of security they make it that much harder for someone unauthorized to gain access.
