Systems and Methods for Fraud Prevention, Supply Chain Tracking, Secure Material Tracing and Information Encoding Using Isotopes and Other Markers

摘要

Encoding information in a material using a material tracing system includes storing information to be encoded in the material, generating a number based on the information, determining an amount of at least one tracer to be incorporated into the material corresponding to the number, and incorporating the determined amount of the at least one tracer into the material. Decoding information encoded in the material includes measuring an amount of the at least one tracer, in some embodiments after tracer activation, determining a number corresponding to the measured at least one tracer, and decoding the number to obtain information associated with the material. A material tracing system is also provided.
