Systems, devices, apparatuses, and methods are described for providing robust RFID security and secure targeted information dissemination. Randomized identifiers for RFID tags associated with products for sale are read by readers of user devices having their own randomized identifiers. Information relating to the products is provided to the user devices by information retrieval systems without exposing information related to the user device or a user thereof. Information security is provided through the use of the randomized identifiers that act as proxies or surrogates for users and user devices. Based on the products and associated RFID tags read by the user device, a retailer or manufacturer provides targeted advertising and sales incentives to the user device through the information retrieval system.
