[citation][nom]mrmez[/nom]Yeah, not convinced.Still think the biometric scan idea is the best.Devices will have built in sensors, automatically detecting unique biometric signatures and automatically unlocking.Either that or implant an RFID tag in your scrotum which locks your device when you stop masturbating[/citation]
No, no, and no.
Biometrics are *not* the solution for security. They can be *used* for security, but only as part of a two- or three-factor identification check. Biometrics by themselves are not secure. Also, you have two problems specific to biometrics:
1) Biometrics, by virtue of their "sci-fi", "ooooh, high-tech" factor, have many people fooled into thinking they are impossible to fake. Therefore, there will be a real tendency to tie someone to their biometrics. As in, your fingerprint is used to validate your identify in Belize to withdraw all the money from your account, there will be a tendency to assume it really was you in Belize withdrawing that money (even if you were in Los Angeles at the time).
2) Once a part of your body is copied, whether your face, fingerprint, or retina, it's rather difficult to get a new one. So, what happens when everything depends on your fingerprint being read but your fingerprint is being used by thieves with their high-tech, fingerprint-reader fooling gummy bears?
In any case, there are some things that can easily be done to improve security significantly:
1) Limit the number of password attempts. If someone fails the attempt, say, 5 times, introduce a time-delay and/or require additional verification. This essentially breaks all attempts at brute-forcing.
2) Stop using stupid, easily guessable/obtainable bits of personal verification for ID checks. Your mother's maiden name, your dog's name, the name/age/birthday of you or anyone you know; crap like this has to go.
3) STOP MASKING PASSWORDS, FFS. It reduces security by making users choose passwords that are easier to type, and increases support costs from people who get frustrated and have to reset their password (and then reset their password with the aforementioned low-security ID checks of personal information). How often are you seriously worried about someone looking over your shoulder (nevermind that they could just as easily look at what keys your fingers are hitting), anyway? And you can easily include a checkbox to mask the password if it's an actual concern.
4) Use passPHRASES instead of passWORDS. Easier to remember, harder to crack. This one is a no-brainer, really.
