A METHOD FOR UNIQUELY IDENTIFYING A PERSONAL COMPUTING DEVICE TO PREVENT THE ABUSE OF TRIAL PERIODS IN A DIGITAL MEDIA CONTENT SERVICE

摘要

The present invention provides a method for uniquely identifying a personal computing device in order to determine whether that device is, for example, entitled to a trial period in a digital media content service. The invention is a method for uniquely identifying a computing device, comprising the steps of: using a tool to read or construct a unique identifier for the device, the tool being a browser plug-in that is programmed to read or construct the unique identifier from one or more Microsoft Windows® management instrumentation sources and is programmed to provide that unique identifier to a remote digital media service.
