Document Authentication using Two Level QR Code

The quick response (QR) code was designed for storage information and high-speed reading applications. In projected QR code authentication a pair of level storage is used, that facilitate to verify original content in QR code. Our projected work uses public and private storage level of document storage. Inside the general public level, same commonplace QR code storage level is explored; which can be legible to any QR code legible device. The private level is created by replacement the black modules by specific rough patches kind cowl image. It consists of knowledge encoded victimization q-r code with misreckoning correction capability. Q-R code will increase the storage capability of the QR code, but in addition to verify the initial document from a reproduction. This authentication is as results of the sensitivity of the used patches to the print-and-scan technique. Steganalytic formula is not ostensibly to defeat our steganographic approach. Third, the reversible capability heritable from our theme provides utility that allows recovery of the availability texture. We have a tendency to tend to weave texture synthesis technique into steganography for concealing secret in image.
