Of course, uploading someone else's degree thesis is an infringement (unless you discuss it with the author of the thesis and the other party agrees). This responsibility must be borne by you, and Baidu does not bear this responsibility. After all, you uploaded the document, Baidu is only responsible for checking the quality and typesetting of the document, and the copyright issue is not his consideration. Moreover, Baidu Library also shows that the uploaded documents are at your own risk. Therefore, you should be extra careful when uploading documents.
