问题描述:
我需要一个可以在图像中嵌入不可见标记(不是大文本信息,最大 256 字节)的程序.但是我找不到一个好的库(使用任何语言,最好是 c/c++).找了很多文献,没有源码.
I need a program that will embed an invisible mark (not big text info, 256bytes max) in an image. But I could not find a good library (in any language, better if c/c++). I found a lot of literature, but no source code.
我找到了一个资源但该程序是为 NetPBM 格式编写的.
I found one resource but that program is writtem for NetPBM format.
需要的方法不是LSB,或者concating等
The needed method is not LSB, or concating etc.

Have a look at steghide, an open-source steganography program that supports JPEG.
