Disclosed are systems and methods for implementation of a rolling key to identify systems inventories. One method may include receiving, by a processing device of an inventory server from a client system, a key and a key component, wherein the key component comprises a random string of characters generated by the client system to uniquely identify the client system; identifying, using the key as an identifier, the client system in an inventory database of the inventory server; transmitting an acknowledgement to the client system that the client system has been identified in the inventory database and that the inventory server received the key component, the acknowledgement to cause the client system to store the key component as part of a new key used to identify the client system; and storing the key component, wherein storing the key component causes a modification of the key used to identify the client system.
