Multimedia Security
1. Control access such that only the right people can access to the multimedia content
2. Prevent illegal duplications
3. Authenticate the multimedia content are from the true sender (prevent impersonation and faked media distribution)
4. Images (Photo), Graphics, audio (music and song) and video can be protected by digital watermark
5. Watermark system makes use of the fundamental property of the human visual system/human auditory system – a visual (or audio) stimulus is less noticeable if superimposed over another large stimulus. Thus digital watermark make use of such properties in human perception and watermark can be added to media by noise masking/distortion masking techniques.
A. Visible Watermark
Visible watermark and copyright information can be added directly to the image.
多媒体安全
1. 通过只有能正确输入密码的人才能获得进入多媒体内容的权利来控制通道；
2. 防止非法复制；
3. 证实多媒体内容是来自真实的发令者(防止假借和伪造的媒介发行)；
4. 数字式水印可以保护图象(相片), 图表, 音像(音乐和歌曲)以及录影；
5. 水印系统利用人类视觉系统及人类听觉系统的特性-如果附加的超过其他的大激励，则视觉（或听觉）激励就显得不那么明显了。数字式水印正是利用了这种人类感觉特性，同时水印可以通过噪声掩蔽以及变形掩蔽技术加到媒介中。
