Utilizing 2D barcodes, many applications such as logistics management, information exchange and identification can be realized. Recently, Taiwan government and industry sectors are striving to promote 2D barcodes related research. Consequently, more and more manufacturers apply 2D barcode technology to the operation of business and factories and good remuneration has been returned.
The 2D barcode has the properties of security and not easy to forge itself because the embedded information cannot be decoded directly. Nevertheless, perfect security is not guaranteed to someone who is familiar with 2D barcode technologies. Information hideaway is indispensable in storing the message in 2D barcode.
In our research, the cryptology has been integrated with 2D barcode technology. RSA algorithm of public- key cryptology has been employed into RSA QR Code to fulfill a guide system. This method can not only enhance the security of the information but also provide diversified services. While 2D barcode technology has been applied in the exhibit exposition or illustration, the intellectual property rights or illegal copy problems can be avoided. Moreover, multiple level accesses to the information can be achieved. We believe such a mechanism can make 2D barcode application more widespread.
