Data Security Using Colored Image Embedding In Qr Code
Abstract
QR Code is generated with insertion of a color image into it with minimal probability of detection errors. With
standard decoding applications these insertions of vital information using QR code into color codes are possible. This
insertion takes benefits of the support of QR readers against interruption of image luminance moreover, the vital information
in QR code bits are transformed into the luminance values of the image which is colored. Then, Multiresolution halftoning
masks algorithm uses for the selection of modified pixels and nonlinear programming techniques with which pixel of the
images are transformed into luminance level, to reduce the visual distortion of the QR image. Here a QR code with colored
image is proposed with new multiresolution technique to offer improved memory efficiency and to minimize processing
time.
