In a geo-blocking scheme, the user’s location is calculated using geolocation techniques, such as checking the user’s IP address against a blacklist or whitelist; the result of this check is used to determine whether the system will approve or deny access to the content. The term is most commonly associated with its use to restrict access to premium multimedia content on the internet, such as films and television shows, for legal reasons—most prominently for copyright and licensing reasons. There are other uses for geoblocking, such as blocking malicious traffic or to enforce price discrimination.
