Graduation design is generally checked, which is a measure taken by the school to ensure students' independence and innovation. The specific methods of duplicate checking may vary from school to school, generally in the following ways:

Through the network duplicate checking system: schools usually buy or use some network duplicate checking systems, such as Turnitin, extraction detection, and HowNet duplicate checking, which can detect whether there is plagiarism in papers. If you use online maps, these systems compare them with other documents in the database. If the similarity is too high, it will be regarded as plagiarism.

Manual inspection by professionals: Some schools will arrange professionals to conduct manual inspection of graduation design. These professionals usually have relevant professional background and rich experience, and can judge whether there is plagiarism in graduation design.

Pass the questions in the defense: During the defense, the teacher may ask questions about some details and viewpoints in the graduation project. If your graduation project is plagiarized, you may not be able to answer these questions.

If you use online maps, you may improve the duplicate checking rate, but as long as you indicate the source when quoting, or you use pictures in the public domain, then this is not plagiarism. In any case, plagiarism is immoral, which will not only affect your academic reputation, but also lead to serious consequences, such as cancellation of your degree and expulsion from school. So, please make sure that your graduation project is original and legal.
