Abstract
In recent years, RFID (Radio Frequency Identification) technology seems to have been more widely accepted. However, there are still some weaknesses of RFID technology, such as low reading rate, data security and the privacy issue, deployment of antennas, problems in handling large amounts of data generated by the tags, reader collision, and failed in the presence of metal and liquid based products ... etc. This thesis developed a RFID Information Platform to handle mass data and try to solve the reader collision problem which may result in low reading rate, moreover, to deal with the data security problems.
In the aspect of the data transmission security, AES (Advanced Encryption Standard) algorithm is employed for the encryption of tag. The transmission protocol of this platform is designed by imitating Secure Socket Layer (SSL) handshake protocol. RSA (Ronald Rivet, Adi Shamir and Leonard Adleman) and AES encryption/decryption algorithms are applied simultaneously for considerations of security and efficiency. The security mechanisms are proposed for the supply chain management. Subsequently, an anti-collision policy called Event-driven reader scheduling (EDRS) is proposed in this thesis. A comparison of EDRS and existing collision avoidance policies (TDMA, Colorwave) was made based on the simulation results. There is a nice outcome of EDRS which is according to the concerned area (workspace) to avoid reader collision.
The security issue and reader collision problem of RFID system are taken into account. Through the integration of web-services, the developed information platform is more flexible and secure. This information platform supports the adapters for 2.45GHz/915MHz/13.56MHz/530KHz readers. In addition, 915MHz reader supports active/passive tags which follow the standards of ISO and EPC. Collected fault data can be diagnosed through the web-service we constructed. SVM (Support Vector Machine) is used for fault diagnosis. Besides, General message passing platform provides various ways of message passing such as Web-Site, SMS, e-mail, videoconference, GPRS and XML…etc. Diagnosing server can send active warning notification to engineers or related staffs for troubleshooting.
