Claim 19:
20. A system comprising:
a user interface logon portal configured to receive a user logon request for authentication;
at least one of an identity store and a multifactor authentication check logic circuit configured to check parameters of the user logon request to determine authenticity; and
a context check logic circuit including
a profile builder logic circuit configured to build a user logon profile with a plurality of user logon features gathered during at least one successful attempted user logon, and determine a logon feature novelty score for each of the plurality of user logon features based on a number of user logon feature events over a total number of user logon events,
a logon score logic circuit configured to receive a user logon request for authentication and extracting current user logon features associated with the user logon request, retrieve corresponding logon feature novelty scores of the current user logon features from the user logon profile based on the extracted current user logon features, and determine a first distance function for the corresponding logon feature novelty scores of the current user logon features, and
a failed logon score logic circuit configured to build a failed logon attempt database with a plurality of failed user logon features corresponding to a plurality of failed user logon attempts, determine a failed logon feature novelty score for each of the plurality of failed user logon features based on a number of failed user logon feature events over a total number of failed user logon events, extract the failed logon feature novelty scores corresponding to current user logon features, and determine a second distance function for the corresponding logon feature novelty scores of the current user logon features,
wherein the system is configured to determine to one of allow or deny the user logon request based on at least one of the first distance function and the second distance function.
