摘要
根据软件水印原理,软件水印可以应用于验?证软件版权所有。其方法是将软件版权信息作为水印内容,以可执行文件作为嵌入载体。在分析可执行文件各节结构存在一定程度的空余存储空间之后,可以利用这些空余空间或者构造空余空间,将水印信息经过加密并设计通用的策略嵌入其中。同时修改可执行文件的相关特征数据,以实现嵌入水印的隐蔽性。嵌入的水印密文可以被提取并解密,从而声明软件版权。
According to the principle of Software Watermarking,It can be applied to validate the software copyright reserved. The method is that the information of software copyright is converted to watermarking and embedded into the executable file which is regarded as carrier. When analyzing that the executable file exists some free storage space,the watermarking can be encrypted and embedded universally and strategically into these free space which can as well be constructed. At the same time the relevant data of characteristics of the executable file should be modified in order to achieve the invisibility of watermarking embedded. The watermarking can be extracted and decrypted in order to state the software copyright.
