| Summary: | 碩士 === 國立東華大學 === 資訊工程學系 === 97 === The distinct property of Radio Frequency dentification (RFID) is the ability to easily and silently track. This property is the basis on which many applications using RFID are developed. However, with the silent tracking ability comes the privacy problem. Recently, a RFID-enabled warranty service information system (RWSIS) was
proposed to provide warranty service for both consumers and companies, and to simultaneously avoid unauthorized tracking. RWSIS uses two tags on the product and the warranty card and still allows the illegal tracking of warranty tag (the tag stuck on the warranty card). It is very unlikely that the consumer will carry product together with warranty card together unless it is for repairs, and one may use an on/off switch or non-removable shielding device on the warranty tag to avoid tracking. In this thesis, we adopt the two-dimensional (2D) barcode instead of warranty tag to solve the privacy tracking issue. An attacker needs physical access to read the 2D barcode on the warranty card, and thus wireless scanning from unauthorized readers is moot. Also, the 2D barcode can carry information in addition to storing the required security parameters, reader identifiers and random numbers, which are also utilized by our proposed RWSIS.
