Weak software watermark method used for software configuration management

Abstract

The invention provides a novel fragile software watermarking method for software configuration management. The basic thought of the method is to fully utilize the frangibility of software watermarking to identify the version alteration of software and take watermarking information as an evidence of version identification and retrieval. The method comprises the following steps of: firstly, grouping program codes; secondly, generating various groups of code program information according to various groups of the program codes; thirdly, splicing the groups of the code program information to obtain integral program information; fourthly, splicing the integral program information, author information and time information to obtain final watermarking information; and finally embedding the watermarking information into a first code line containing a program start character of a first group of programs and a final code line containing a program end character of a final group of programs in a write file mode to obtain a program containing the watermarking information. The proposal can effectively overcome and solve the disadvantages and problems existing in the prior software version control method in the software configuration management, and can also be applied to technology such as software tamper resistance and content authentication at the same time.

Description

technical field [0001] The invention belongs to the field of computer science and technology, and relates to technologies such as software engineering, coding theory, computer algorithm, cryptography and computer program design, and in particular to software watermarking technology and software version control technology. Background technique [0002] As a new research field, software watermarking has received more and more attention from the industry. Scholars at home and abroad have paid more and more attention to the research of software watermarking. Compared with media watermarking such as images, software watermarking has more practical significance and can It will bring huge economic benefits to my country's informatization construction. With the rapid development of information technology and Internet technology, the software industry is facing great development opportunities, but also faces many challenges. But the following side effect is that the digital products ...

Problems solved by technology

[0017] (1) It is not automatically known that someone has modified a certain part of the program (or document);

[0018] (2) Due to some special reasons, the content of the local program code (or document) has changed, but the version has not changed, so it cannot be submitted normally

As a result, the program has changed, but the version number of the program has not changed, so that the new program cannot be submitted normally;

[0019] (3) Due to some special reasons, the local program code has not changed, but the version number of the program has changed abnormally;

[0020] (4) When the project situation is more complicated, this technology correctly controls the version number, and the overhead is very large
