Abstract
Embodiments herein provide a server including a memory and an electronic processor. The server includes a UDID database. The electronic processor is configured to receive an identification request regarding a currently-observed user device having a first set of attributes associated with the currently-observed user device. The first set of attributes includes an IP address of the currently-observed user device. The electronic processor is further configured to generate an IP hardened UDID associated with the currently-observed user device based on the first set of attributes, and store the IP hardened UDID in the UDID database. The generation of the IP hardened UDID compensates for changes in the IP address of the currently-observed user device over a period of time.
