A REVIEW ON STEGANOGRAPHY AND DATA HIDING IN QR CODE

Abstract

In comparison to 1D barcodes, a two-dimensional matrix is regarded as a Quick-Response (QR) code which is a programme that contains a vast quantity of data. QR codes offer quick scanning, omnidirectional reading, and a variety of other benefits, such as error correction. Barcode scanners can readily reveal the content of QR codes. In reality, however, gratified QR apps could contain confidential information, like an electronic-ticket or an electronic-coupon. To safeguard quick response essence from unauthorized users or scanners, it should be password protected. We'll look at QR codes and different sorts of QR barcode steganography mechanisms in this article.
