Ultra-privilege detection of papers is a technology used to determine the true author's identity of a text or a paper, aiming at identifying the author's identity hidden in the text, especially in the case of anonymity or forgery.

In the academic and publishing fields, ultra-authority detection can be used to detect academic misconduct, such as plagiarism, ghostwriting, misappropriation of other people's research results and so on. By analyzing the language features, style and vocabulary usage of the text, we can identify the author's unique writing style and characteristics, thus helping to identify the real author of the paper.
