The behavioral biometric of keystroke dynamics uses the manner and rhythm in which an individual types characters on a keyboard or keypad. [ 13 ] [ 14 ] [ 15 ] The user's keystroke rhythms are measured to develop a unique biometric template of the user's typing pattern for future authentication. [ 7 ]
Keystroke dynamics, or typing dynamics, is the obtaining of detailed timing information that describes exactly when each key was pressed and when it was released as a person is typing at a computer keyboard for biometric identification, [32] similar to speaker recognition. [33] Data needed to analyze keystroke dynamics is obtained by keystroke ...
The origins of keystroke inference attacks can be traced back to the mid-1980s when academic interest first emerged in utilizing various emanations from devices to deduce their state. While keystroke inference attacks were not explicitly discussed during this period, the declassified introductory textbook on TEMPEST standards, NACSIM 5000 ...
The keystroke-level model consists of six operators: the first four are physical motor operators followed by one mental operator and one system response operator: [5] K (keystroke or button press): it is the most frequent operator and means keys and not characters (so e.g. pressing SHIFT is a separate K operation). The time for this operator ...
[2] [3] [4] Many organizations, including governments, publish and share their datasets. The datasets are classified, based on the licenses, as Open data and Non-Open data. The datasets from various governmental-bodies are presented in List of open government data sites. The datasets are ported on open data portals.

Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, [1] [2] typically covertly, so that a person using the keyboard is unaware that their actions are being monitored. Data can then be retrieved by the person operating the logging program.
A keystroke sequence like STO 4 2 (store the currently-displayed number into memory 42) would be encoded as 42 42. In this case the first 42 is the key code for the STO key, but the second 42 is not a key code, but a memory register number. The calculator knows to interpret it as such because that's what has to follow the code for the STO key.
