Low cost RFID real lightweight binding proof protocol for medication errors and patient safety.

An Institute of Medicine Report stated there are 98,000 people annually who die due to medication related errors in the United States, and hospitals and other medical institutions are thus being pressed to use technologies to reduce such errors. One approach is to provide a suitable protocol that can cooperate with low cost RFID tags in order to identify patients. However, existing low cost RFID tags lack computational power and it is almost impossible to equip them with security functions, such as keyed hash function. To address this issue, a so a real lightweight binding proof protocol is proposed in this paper. The proposed protocol uses only logic gates (e.g. AND, XOR, ADD) to achieve the goal of proving that two tags exist in the field simultaneously, without the need for any complicated security algorithms. In addition, various scenarios are provider to explain the process of adopting this binding proof protocol with regard to guarding patient safety and preventing medication errors.
