What's more, we also study some key techniques and realization difficulties of image authentication in-depth, including referent block to help tamper localizing, sign bit adjustment for binary encoding, mean quantization improvement, diagonally extension to help tamper localizing, and discard isolated error point to tolerate incidental distortion. These techniques can be used for good reference to the development of image authentication technique.

此外，我们还对数字图像鉴别的一些关键技术和实现难点进行了深入研究，主要包括有：参考点辅助定位技术、二值编码中的符号处理技术、均值量化方法的改进技术、对角扩展和去除孤立点技术等，这些技术的研究都对数字图像鉴别技术的发展具有很好的借鉴意义。
