Abstract: A system and method for monitoring usage or user behavior when using resources over a network, e.g., a behavioral information of a web user browsing web pages on selected web sites is provided. The behavioral information is stored and is available for further analysis. When a user visits a web site, the user is given an option to download and install an agent program. The agent program monitors the user's behavior on selected web sites and uploads the behavioral information to a server. The server collecting the information is typically not related to the web sites being monitored. The behavioral information is provided from the agent to the server with a least amount of intrusion on the user device resources and at the same time protects the user identity and privacy. The behavioral information may be provided to any entity interested in knowing user's behavior on a selected list of web sites.
