Abstract
The present invention provides a method and system for location-based digital rights management. Digital rights for protected content are restricted to a specific location or region by specifying the approved location of the consuming device within the license. This allows the content owner to specify the geographic locations/regions at which the protected content may be consumed. The device obtains its location from a location entity which is then evaluated against the location constraint within the license. If the device is within the location constraint then the content may be accessed. Acquiring the location of the device before allowing access to certain content helps in preventing a user from accessing a protected document in an area which is considered a prohibited location as defined within the license.
