A new multi-template selection algorithm for keystroke dynamic identity authentication
LI Fu-xian · Computer Engineering and Science · 2014
Sample collection and the establishment of the template are crucial for keystroke dynamic identity authentication systems.So far,the single template systems cannot decrease the false reject/accept rate(FRR/FAR)into the reasonable range.The multi-template method is introduced into the keystroke authentication,and then a new multi-template selection algorithm is proposed to balance the FRRand FARafter the most/least authentication probability algorithm is presented.Experiments are done to compare the proposed algorithm with the GMMS,and the factors that can influence the authentication results are analyzed.At last,the advantage of multi-template system is also shown,compared with the single-template authentication systems.
