Data Security Using Colored Image Embedding in QR Code

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, multi-resolution half-toning 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.
