The invention belongs to the field of user
identification technology, and particularly relates to a user
identification system based on keystroke rhythms and an identification method thereof. The method comprises the following steps: acquiring and analyzing all keystroke rhythms after a user logs into a
system to obtain the confidence degree of the current login user, and judging whether the identity of the current login user is legal according to the confidence degree of the user; and meanwhile, performing continuous identity
verification for the user to judge whether the
current user is a legal user, and performing permission
verification for the user again when the confidence degree of the user is lower than a preset early warning threshold. According to the user
identification system based on the keystroke rhythms and the identification method thereof disclosed by the invention, the identity of the user can be identified through keystroke
rhythm data of the user, the user does not need to carry out other
authentication behaviors during identification, the user experience can be improved through the fully transparent identification of the user, the operations of the user cannot be affected, a continuous
identification scheme is adopted to perform uninterrupted identification and
authentication for the identity of the user, and thus the ability of the
system to
resist illegal intrusions can be enhanced, and the security of the
system can be effectively improved.
