| 摘 要： | 针对数字化图像文档因随着数字相机像素质量的提升而变大，使其在网络传输过程中耗费更多传输时间的问题，提出了一种结合JPEG (Joint Picture Experts Group)数据压缩的可逆式隐藏技术，运用该技术可缩短影像传输的时间并且在影像传输的同时可传达隐藏的秘密数据.实验结果证明，文中所提技术可成功实现具有压缩的可逆式数据隐藏.

| Abstract: | The size of digital image file will be increased or become larger along with the digital camera’s quality.So,it will spend a lot of transmission time when the digital image is transmitted.In order to speed up the transmission rate and enhance the image’s security,this paper proposed a robust reversible data hiding method based on JPEG image.According to our experiments,it will be able to reduce the image transmission time and keep good secure lever at the same time by using this technology. |
