Keystroke Dynamics keypress latency dataset

This sample set is based on the typing records of different physicians typing evolutive summaries of their patients in a production environment during a time period of one week. This is not an always-typing task, sometimes they must edit text. Arrow keys are recorded too. The file is formatted in JSON. Due to physician-patient privacy issues the key codes had been removed only leaving the set in this scheme:

{ud:latency_array,dd:latency_array,du:latency_array,uu:latency_array}

where latency_array are random shuffled integer arrays representing the time in milliseconds between two events of the type up (u) or down (d). So for example “dd” is the latency between the pressing of a key and a second one (as in shift+t).
