Abstract
A method and system for optimizing segregation between human-operated clients and machine-operated clients accessing computing resources are provided. The method comprises receiving, from a client, an authentication request, wherein the authentication request is received in response to a redirect request sent from a remote server to the client; dynamically selecting at least one authentication challenge from a plurality of different authentication challenges; sending the at least one generated authentication challenge to the client; determining whether a notification call is received from the client during a predefined time interval; and upon receiving the notification call during the predefined time interval, confirming that the client passes the authentication challenge, wherein a client that passes the authentication challenge is a human-operated client.
