Keeping confidential data and hiding it from unauthorized people has become a real challenge nowadays, cryptography play a major role for secured data transfer. Quick Response Code (QR Code) are tow-dimensional barcodes that encode data. QR code can be used in many fields such as business, marketing, educations, information security, authentication etc. They are able to encode information in both row and column direction, thus able to encode Large amount of information. In this paper, a suggested cryptography technique Depend on Quick Response code (QR code), this technique encrypts secret message by using Advanced Encryption Standard algorithm (AES), then hide secret message in Quick Response code, and is saved as black and white image. Arnold transform was then applied to the Quick Response Code, which performs the scrambling operation by alteration the pixel Placements of an QR code image randomly, finally the Encrypted Arnold transform image is then decomposed into five coefficients using the Shearlet transform, Shearlet have been applied to image for enhancement. results of the experiment show that the proposed method has more security and enhances the confidentiality.
