Image Hidden Technique Using QR-Barcode

In this paper, QR(Quick Response) bar code and image processing techniques are used to construct a nested steganography scheme. There is a lossless data embedded into a cover image. The lossless data is text that is first encoded by the QR barcode; its data does not have any distortion when comparing with the extracted data and original data. Since the extracted text is lossless, the error correction rate of QR encoding must be carefully designed. We found 25% error correction rate is suitable for our goal. After simulation, it is evident that our scheme is robust to JPEG attacks.
