：本文描述了一种基于LSB 扩展的图像自嵌入方法。该方法在使用LSB 数据隐藏的同时，对图像的高层位

平面采用无损数据嵌入方法，将图像的压缩信息与认证信息嵌入到图像自身中。-This paper presents a method of image self-embedding, which is based on the extension of LSB data hiding

method. When LSB embedding method was used in data hiding, reversible hiding method was applied in higher bitplanes

as an addition of LSB embedding capacity
