ABSTRACT
The technique reversible data hiding with the application associated with the Quick Response codes. QR codes are random patterns, which can be commonly observed on the corner of posters. The goal of QR codes aims at convenience oriented applications for mobile phone users. People can use the mobile phone cameras to capture QR code and corresponding to the QR code can be accessed instantly. To develop Quick Response Codes are a type of two-dimensional matrix barcodes used for encoding information. It has become very high storage capacity. The present QR is a combination of strong encryption algorithm and data hiding in two stages to make the entire process extremely hard to break. Here, the secret message is encrypted first and hide it in a QR Code. The QR code is that carry meaningful information in the vertical direction as well as the horizontal, hence the two-dimensional term. By carrying information in both directions, QR code can carry up to several hundred times the amount of data carried by an ordinary bar codes. With the aid of our reversible data hiding technique, the QR codes can be hidden into the original image, and considerable increase in embedding capacity can be expected. Then, the QR code could get vanished and the original image would be recovered to retain the information conveyed therein.
