The impact of database quality on keystroke dynamics authentication

“…Fig. 1 shows the results of this comparison where the flight-to-dwell importance (ratio of corresponding weights for distance [7]) is presented in horizontal axis. Fig.…”

“…Partial distances for two given samples were calculated using Manhattan distance (for corresponding dwells and flights). Both flight and dwell times are important and if we take only one of them into account, the rate of proper classification decreases significantly, as the authors presented in [7].…”

Advances in the Keystroke Dynamics: The Practical Impact of Database Quality

“…The authors' latest approach [8] was to calculate initial weights for all expected key events. However, during tests with Keystroke Dynamics -Benchmark Data Set it turned out that the classification results are better with the use of the former algorithm [7]. The possible explanation of this phenomenon is given in section 5.…”

“…Both flight and dwell are important as the authors presented in [7]. In the previous experiments the authors had determined the best p ratio value as 0.7.…”

“…In [5] voice, hand geometry and face image are used together. This paper is organized as follows: section 2 describes state of the art in keystroke dynamics, section 3 presents two databases: database KDS created by the authors and Keystroke Dynamics -Benchmark Data Set [6] database available online, section 4 presents briefly the fundamentals of the authors' classification approach to keystroke dynamics (for details please refer to papers [7]- [9]), section 5 presents classification results and problems related to database quality regarding keystroke dynamics, finally section 6 concludes the paper.…”
