1. Collecting evidence: Students can first collect evidence to prove that the first draft of the paper has indeed been leaked, such as keeping records of emails, text messages or other correspondence with tutors and members of the defense committee, or having other materials to prove the existence of the first draft of the paper.
2. Contact with relevant parties: Students can contact the school, state the situation to the school and provide relevant evidence. Students can ask the school to investigate this matter and take appropriate measures to safeguard their rights and interests.
3. Consultation with legal professionals: Students can consult lawyers or legal professionals to understand their legitimate rights and interests and feasible rights protection measures. Lawyers can help students evaluate the situation and provide corresponding legal advice according to the specific situation.
4. Protect personal information: Students can take some measures to protect their personal information to avoid further damage. For example, students can limit the scope of sharing personal information or the first draft of a paper and try to avoid spreading it to others.
Please note that the above suggestions are for reference only, and the actual situation may be different due to different regions and legal systems. When students face similar situations, it is best to consult local legal professionals to get accurate legal advice.
