Abstract
A computer implemented method of access control for a user device having at least one component for determining behaviors of the user. The method including accessing a first machine learning classifier trained based on at least one prior behavior of the user using the device, the classifier classifying user behavior as compliant or non-compliant. The method further including, in response to a determination that a subsequent behavior is classified as non-compliant, accessing a second machine learning classifier trained based on at least one prior behavior of the user using the device where the prior behavior is classified as non-compliant by the first classifier. The method further including, in response to a determination that the subsequent behavior is classified as non-compliant by the second classifier, requesting a credential-based authentication of the user and constructively training one of the machine learning classifiers based on the credential-based authentication result.
