Abstract

A system and method for preventing web scraping which includes receiving a request between a web client and a web server for the web client to receive web content. A client side language script is injected into a response to be sent to the requesting web client, wherein the client side language script contains an event listener to detect a keystroke and/or a mouse movement at the web client. Information is collected from the client side language script relating to whether the keystroke and/or the mouse movement were detected. The web client is selectively allowed to access the web server to receive the web content based on the collected information.
