| Outline of Final Research Achievements |
In this research, we propose a reversible steganography technique and apply it to image tampering detection and recovery. The proposed method achieves a flexible and secure image transmission by combining a watermarking technology and a channel coding scheme. From our simulation results, we show that tampering can be detected using images of various resolutions. In addition, the proposed method can extract copyright information from the received image and restore the original image without quality degradation.
