2009-02-20 23:40:15 Dustin Kirkland  ecryptfs-utils: statusexplanation Hi, thanks so much for the bug report. I've been thinking about this quite a bit lately. I'm going to have to mark this "won't fix" for now. The prevailing opinion from security professionals is that fingerprints are perhaps a good replacement for usernames. However, they're really not a good replacement for passwords. Consider your laptop... How many fingerprints of yours are there on your laptop right now? As such, it's about as secret as your username. You don't leave your password on your spacebar, or on your beer bottle :-) This wikipedia entry (although it's about Microsoft Fingerprint Readers) is pretty accurate: * http://en.wikipedia.org/wiki/Microsoft_Fingerprint_Reader So, I'm sorry, but I don't think we'll be fixing this for now. :-Dustin

That said, someone else may have a really good reader and want to use it, and I'd have to agree with Roger that just because I, Dustin and other security professionals don't find them useful for passwords, that doesn't mean they shouldn't be supported, if those interested want to put in the work. Combining a fingerprint reader with other authentication mechanisms can make things more secure. Eg, the fingerprint (something that uniquely identifies you), with a password (something you know) and a smart card/usbkey (something you have) would offer quite strong protection (not to mention rather severe usability issues). In this scenario an attacker needs to obtain three different tokens, which is likely more difficult than two and certainly more than just one.

At this point, I'm marking this bug 'Triaged', which should be a marked upgrade from 'Won't fix' ;-) For the reasons that I've previously mentioned (I don't have a fingerprint reader, and wouldn't use one even if I did), I personally won't be implementing this. However, as my cohort Tyler says, if someone comes forward with a good, working, tested patch, I would certainly merge support into the eCryptfs upstream codebase. It should be quite possible to implement, as a generic PKCS-11 token within the existing eCryptfs key module framework. :-Dustin
