Above is by a "maintainer of eCryptfs" noting that we would otherwise leave our passwords on everything we touch and without option when that password is compromised. I wonder though, is there a biometric facet that can surmount the bar of unreplicable uniqueness? Contact lenses can fool iris scanners. Perhaps we should make a dental impression sensor?
Unique? Maybe. Unreplicable? I can't imagine so, we're all just a bunch of molecules. At some point in the perhaps-not-too-distant future, we will likely have very sophisticated brain-scanning technologies, and combined with advances against biometric methods, basically any form of authentication will be useless. I have absolutely no idea how to get around this, and can only hope that our society has advanced enough…
Synopsis: an evil government steals the private thoughts and passwords of its citizens, most of whom are unaware of the threat. A few paranoid individuals come up with increasingly bizarre biometric passwords, but the government has secretly approved unauthorized (and speedy) cloning to bypass these protections.
Finally, the freedom fighters use the government's own technology against it, replicating the president's bio-metrics in order to shutdown and disclose the program.
No meaningful political change occurs.
