The QR is short for Quick Response. They can be read quickly by a cell phone. They are used to piece of information from transitory media and put it in to your cell phone. Every QR code consists of number of black square and dots which represent certain piece of information. In this paper represent an new rich QR code that has two storage level and can be used for document ownership i,e authentication. The two level QR code has a public and private storage level. The public storage message is stored in the standard QR code, using the classical generation method. The private storage level make by replacing Black module by specific textured pattern. The information encoded using q-ary code with error correction capacity. This method is not only increases the storage capacity of the code, but also recognize the original document from a copy. The document ownership is due to the sensitivity of used patterns to print and scan P&S process. The second- level used the pattern recognition method for read the information can be used in private message sharing and ownership i,e authentication scenario. It is based on maximizing the correlation value between P&S degraded pattern and reference pattern. The storage capacity can be expressively improved by the increasing the code alphabet q. The also storage capacity increases the using increasing the textured pattern size. It also highlights of using this new rich QR code for document ownership.
