Paper duplicate checking system mainly detects the content of papers and the degree of repetition of published papers, and mainly examines the ideas and formats of papers. The author's statement belongs to irrelevant content, and the repetition rate is not calculated if the signed author does not repeat it. But if the format is wrong, it may also be counted as repetition rate. Some schools or disciplines may have regulations that require statements to be included in papers. Students need to carefully check the duplicate checking rules of the school and abide by them.

Please note that different schools and different disciplines may have different requirements for paper duplicate checking. Please read carefully and abide by relevant regulations, and be sure to use formal duplicate checking systems, such as HowNet, paperfree and papertime, to prevent papers from being leaked or sold.
