Problems solved by technology
[0004] The current detection methods have a good effect on the identification of code plagiarism, which can identify which codes are plagiarized, but there is also a defect, that is, the influence of the propagation of the identification software code cannot be removed
For example, there is a software A that is very popular and was first developed, and is referenced by many other software. If software B references software A, and software C also uses software A, then the current homology detection method may not only It is reported that B references software A, and it may also report that B also references software C, but in fact, software A is the final result that should be found, which will cause redundancy or false positives in the detection results

The embodiment of the invention provides a software homology detection method and device, equipment and a storage medium. The method comprises the steps of obtaining at least one code file of to-be-detected software; performing fingerprint calculation on each code file to obtain first fingerprint information corresponding to each code file; for the first fingerprint information corresponding to each code file, determining whether second fingerprint information the same as the first fingerprint information exists in a database or not, the database storing a plurality of code files and fingerprint information corresponding to each code file, and at least one code file not belonging to the database; if second fingerprint information the same as the first fingerprint information exists in thedatabase, determining a target code file according to a code file corresponding to the second fingerprint information, and the target code file being the earliest source file of at least one code file; and determining the homology of the software corresponding to the target code file and the to-be-detected software. According to the embodiment of the invention, the software homology detection precision can be improved, and the false alarm rate is reduced.
Description
technical field [0001] The embodiments of the present application relate to the technical field of computer software, and in particular to a software homology detection method, device, equipment and storage medium. Background technique [0002] Source code (also called source program) refers to an uncompiled text file written in accordance with a certain programming language specification, which is a series of human-readable computer language instructions. There are many identical or similar code fragments in the source code of a software system, these code fragments are called clone codes, and they have homology. Software homology detection refers to detecting whether there are code fragments that are the same as or similar to other software in the source code of the tested software, so as to serve as an important basis for whether the software is reused or plagiarized. [0003] Common source code homology detection methods include text similarity and functional similarity...
