- What it is
- A 1990 article in Communications of the ACM, by Rick Joyce of AT&T Bell Labs and Gopal Gupta of James Cook University, that proposes using the timing between keystrokes to verify a user's identity and reports trial results.
- How much weight it carries
- Peer-reviewed and widely cited in the keystroke biometrics literature. The full text is behind a paywall, so this record uses the abstract only; the trial sample size and error rates are not in it.
Facts taken from this source
- Joyce and Gupta's 1990 abstract describes the stream of latency periods between keystrokes as a unique digital signature.
