TL;DRAbstract

With the promotion by the government and enterprises, Quick Response Code (QR-Code) has gained increasing popularity in Taiwan and expanded its applications to various aspects. The main function of QR-Code is to store various types of data and enable users to access the stored data using code readers. However, the easy access to QR-Code through code readers brings up the issue of security control of sensitive materials. There have been various encryption mechanisms proposed for QR-Code, but so far the encrypted QR-Code can only provide the same set of data to all users. Based on the Direct Sequence-Code Division Multiple Access(DS-CDMA) concept, this study developed a novel encryption mechanism which can identify different users and provide different sets of data according to user’s identity. In addition, we use QR-Code medical identification as our the actual application cases. The role different between on of doctors, nurses, and so on. According to the various roles require differen
