摘要

提出了一种基于小波域的图像认证方案。在选定的子带系数的大小是根据位平面数据确定的。从该数据生成图像特征，然后将其签名为数字签名。签名可以嵌入到主机映像中，也可以单独发送。该特性只有256字节。该方案可以有效地进行图像认证。

A new image authentication scheme using bit plane feature of wavelet coefficient

This paper proposes a new image authentication scheme, which is done in the wavelet domain. A magnitude of coefficient in selected sub-bands is determined in terms of bit plane data. An image feature is generated from this data and then signed to be a digital signature. The Signature can be embedded into host image or separately send. The feature is only 256 bytes. With the proposed scheme, image authentication can be performed effectively.
