The KBOC16 database
The KBOC16 database is part of the KBOC competition, an official competition of The IEEE Eighth International Conference on Biometrics: Theory, Applications, and Systems (BTAS 2016) organized by ATVS Biometric Research Group.
The database consists of keystroke sequences from 300 subjects acquired in four different sessions (5 samples per session including genuine and impostors) distributed in a four month time span. Thus, three different levels of temporal variability are taken into account: (1) within the same session (the samples are not acquired consecutively), (2) within weeks (between two consecutive sessions), and (3) within months (between non-consecutive sessions).
Each session comprises 5 case-insensitive repetitions of the subject’s name and surname typed in a natural and continuous manner (case insensitive). Mistakes (and backspace) are not permitted. The time (in milliseconds) elapsed between consecutive key events (press and release) is provided as keystroke dynamics sequence.
There are two types of sequences: 1) Genuine sequences: typed by the owner of the password and 2) Impostor sequences: typed by other users (different to the owner) who try to spoof the system. The number of genuine and impostor samples per user varies (this information remains sequestered).
