AdmitOne's Security Scout can tell users apart based on the way they type keystrokes when logging into an account. This is a form of biometric password checking, and we've seen the same kind of approach applied to writing signatures. Online, there's another benefit: it helps identify password sharing. According to Venture Beat:
The only way most companies can detect account sharing now is if multiple people try to log into one account at the same time from different locations. But AdmitOne uses a combination of the keystroke identification, the digital fingerprints of the computer used, and the Internet Protocol (IP) address of the Internet connection used to access the account.
The story says:
The Security Scout software needs 12 keystrokes to recognize a user. On those keystrokes, the software records 47 different measurements. Among the important measurements are "dwell time," or the amount of time someone holds down a key and "flight time," or the time between keystrokes. Security Scout then presents the data on the account sharing in a graphical way.
AdmitOne's big advantage is that it works without needing any specialised hardware.
