The one context where I've seen something like this that I thought was interesting was in an online MOOC. Presumably it would be trivial to give your account credentials to someone else in order to have them pass a quiz/test on the platform for you, or to write our essay. They used something similar to match the typing pattern compared to some other sample that had been taken when identity was verified off-band, so then in subsequent submissions of writing samples in the platform, they could have more confidence that it was submitted by the original student.
