We have a number of different concepts related to "fingerprints" on this site:
- Physical fingerprints, e.g. for use in biometric authentication.
- Fingerprinting software (and hardware?), i.e. trying to determine what software or what version is running by observing it's behaviour.
- Fingerprinting users, alá the Panopticlick. Note that this is different from the above point, in that it aims to identify a specific instance of the software, and not just a specific software.
There might be more categories. For instance, I am not sure where this question would fit in. Anyway, our tags do not match these concepts very well:
fingerprint (63 questions):
In information security, a fingerprinting algorithm uniquely identifies the hardware, software or data. Just as human fingerprints uniquely identify people for practical purposes. This fingerprint may be used in penetration tests or for vulnerability management.
fingerprinting (92 questions):
Gaining information about current version of an application or operating system in order to find a vulnerability.
os-fingerprinting (17 questions)
How could we sort this out? Here are a few thoughts, but I will leave it to the answers to outline full solutions:
- There should probably be a specific tag for physical fingerprints. I know, there is biometrics, but that is a very broad area.
- Since the word "fingerprint" is ambiguos, we should avoid it in tag names without qualifiers. E.g. there could be software-fingerprinting and biometric-fingerprint, but no fingerprint.
- I think 2 and 3 should probably be separated in different tags, but I am note sure how to do that or what the proper terminology is.
