A technique for uniquely identifying devices without explicitly provided device or user identifying information in a networked client-server environment, e.g., the Mobile Internet, in which content is downloaded from a server to a device browser executing at a client device, and using static XML markup tags embedded in the content in a manner transparent to a user situated at the device browser, derives a globally unique device identifier. Device identifying information is captured and maintained in a device profile database associated with a globally unique device identifier. Specifically, mark up code embedded into a referring content page effectively downloads software from a distribution server, and then instantiates the software in the client device browser. The software transparently and dynamically inserts an Internet address request to a device identification management system. The device identification management system selects a device profile associated with a previously detected request from the device and retrieves its globally unique identifier from a database of all profiles for all previous devices requesting unique device identifications. If a matching profile is not found in the database, the device identifying information associated with the request is entered as a new device profile along with a globally unique identifier associated with that specific device in the database. The globally unique identifier is delivered back to the device or external systems for their own use, e.g., mobile Internet advertising management systems.
