Quick response codes or QR codes are increasing their popularity as they appear in more places in the todays scenario. Quick Response Codes can be considered as physical hyperlinks that give the ability to users to access information, share messages and authenticate the documents. Apart from marketing, QR Codes have been also adopted in different areas such as the on-line payments. As the usage of QR codes is increasing day by day care must be taken while designing the QR code so that there arent any issues regarding its security and privacy. In this paper we have proposed a technique known as 2 level QR code which consists of two layers of security provided to the QR code. The first level is known as public level and the second level is known as private level. We will be using Reed Solomon algorithm. Our two level architecture is capable enough to provide ample security and privacy as far as private message sharing and document authentication are concerned. In this paper we have studied various state of the art existing techniques of designing QR code along with their comparison with the our proposed 2 level QR code technique.
