It is a special type of barcode that can encode information like numbers, letters, and Japanese characters. Decorating QR Codes such they are more attractive and stylish is simple as they are just a graphic. Now, decorating QR Codes has been taken by some artists to a level of an art as a trick for good selling. Some decorative means will not affect QR Code readability. In this study, we propose a mechanism which associated the QR Code decoration and data hiding technique to hide some private or secret message and preserve the code readability. The embedding technique with decorating QR Code is different from traditional image data hiding on seeking purposes for high capacity and low distortion. It just decides where the decorating patterns occur for secret message to embed. In addition, QR Codes include error correction, people can accurately read the message equipped on them by QR reader. As the customization and personalization in marketing and manufacturing, the embedded secret message on decorating QR Codes can protect the authorization about the products to customers. This authorization mechanism is high applied and worth to develop. Finally, the experimental results of the proposed method show the efficiency of its.
