Abstract
A routing system that can receive, decode, and route messages from electronic tracking tags made by different manufacturers and issued by different tag issuers. Tracking tags may be placed on items that are shipped or stored, and wireless messages from the tags may be used to track the items and their status. The system enables a site to use a single gateway that obtain messages from heterogeneous tracking tags; the gateway forwards messages to the routing system for processing. The system may access a tag manufacturers database that contains a descriptor of the messages from each manufacturer's tags, and a tag registrations database that lists tags associated with each tag issuer. The system supports tag messages with encrypted contents and with tag identifiers that are rotated to prevent malicious tracking, and it may check message integrity to detect modification of the message after it is sent from the tag.
