Open the original (DOI 10.1155/2013/408280)- What it measures
- The survey reviews published keystroke dynamics research from the past three decades. This passage sits in its list of disadvantages of the method, next to its advantages.
- What it does not show
- A review of earlier studies, not a new test. The sentence is general, and it does not give an error rate. It is the survey's own summary of the field in 2013.
