System and Method for Randomization for Robust RFID Security

摘要

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