Abstract:
1. A method of performing authentication of a user, the method comprising: receiving, by an authentication device, values of a set of predictors from an electronic device local to the authentication device; generating a risk score based on the values of the set of predictors, the risk score being indicative of a likelihood that the user is an authorized user that the user asserts to be; and sending the risk score to an authentication server located remote from the electronic device, the authentication server being configured to provide an authentication result based on the risk score, the authentication result indicating whether the user is the authorized user that the user asserts to be; wherein the set of predictors includes values of a set of attributes and a value of an identifier of the authorized user; wherein the risk score includes a naïve Bayes model that is based on i) the values of the set of attributes and ii) the value of the identifier of an authorized user; and wherein generating the risk score includes producing a probability of the user being the authorized user; wherein producing the probability of the user being the authorized user includes:
