Abstract: A technique to control access to computer network resources at a computer facility permits a user to interact with the computer facility through a computer node of a network, wherein the user interaction comprises language learning responses submitted to the computer facility through the computer node, and a user authentication process is performed to determine if the permitted user interaction is authorized. The user authentication process is performed with user authentication information that is obtained by the computer facility during the permitted user interaction and also with user authentication information that is extracted from the user's language learning responses. In this way, user authentication occurs without intruding into the utilization of the computer facility.
