中文摘要：

传统的信息加密是通过置乱信息的内容来隐蔽信息,使秘密信息被人看不懂,这反而暴露了信息的重要性,容易受到攻击。相反,信息隐藏不仅隐匿信息的内容,而且隐蔽信息的发送者、接收者,甚至隐匿秘密信息的存在,这比信息加密更安全。

英文摘要：

Information encrypting tries to hide the contents of a message,that is,the message is scrambled so that it can not be understood,which however indicates the messages important,so that it can be easily attacked.In contrast,information hiding,is to conceal the fact that a message and its sender,its receiver or its existence are hidden so that it can not be seen,so it is safer than information encrypting.
