| Abstract(in English) | Real-space things often make groups. Confirmation of a group is usually referred to as grouping proof. In this paper, a grouping proof method which does not require an external verifier and data-base access is proposed. The proposed method leverages the read and write functionality of RF tag. A hash number is derived from unique ID of an RF tag. The exclusive OR operation of the hash numbers in a group yields a group ID, which is written into each RF tags memory. With the group ID we can identify unexpected involvement of things. We also can detect and identify missing object (RF tag) using a hierarchical group coding. The probability of the false-positiveness is mathematically evaluated. The practicability and required time to make a group and confirmation are also evaluated with an HF RFID system. The confirmation of a group of five tags requires about 0.03 second, which shows the practicability of the proposal. |
