Changying Sun · Computer Knowledge and Technology · 2010
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.
