Now a days, most of peoples are working with smart devices with the digital data for their regular survive in the world. The QR codes are use to store the digital data in form of black and white modules. QR codes are use in many applications related to security, academics, marketing etc. Now, peoples are well aware with this technology and they are use QR codes for various purpose. The QR codes are known at worldwide and getting popularity to use smart phones by the peoples. These are type of optics labels and only read by machines. The human-being can not access the data from QR code without using smart applications for scanning the code. There are static and dynamic QR codes and create by using code generators. The QR codes are gives the link to get information about particular subject. If data is important then user can use QR code to store that data with various other techniques. Hence another user cannot access data without having authority. There is a new system of QR code use for data security purpose. That is called two level QR code, because it is having two parts to store data. One part is for public data and it is generated by standard process. It can be reads by any application which is standard QR code reader. The second part of QR code is for private data and it will generates using Reed-Solomon algorithm and visual cryptography. Using these methodologies time requirement of process is become less, because it is automates the combination of textured patterns. These patterns are replaces the black modules of the QR code. Because of using texture patterns, there will be increase storage capacity of the QR code. Data security is main focusing concept for our proposed approach and for that key is used with private QR code to decode the data.
