Dependable data management in the IoT traceability system

Abstract

The IoT traceability system based on RFID asks the high reliability of the data management, each data item is valuable and indispensable. A RFID based organic food traceability system is introduced in this paper, and some deepgoing discussion about data reliability is given on the following three segment, the data collection, data uploading and data management. RFID encryption and other techniques are used to improve the data legality in the data collection segment. The uploading task is designed as a standalone process to enhance the stability of data uploading, and the data will be kept in the terminal reader device for several days to deal with the server disaster. The data managed in the server is physically deleting prevented as the user may do the misoperation, and the backup server can further improve the data dependability.
