<![CDATA[As digital applications continue to expand across various fields, the importance of reliable electronic data evidence and an efficient notary system has become even more prominent. The improper handling of electronic data not only affects the fairness of judicial proceedings but also poses threats to the legitimate rights and interests of individuals and organizations. This paper analyzes the characteristics of notarial system in different countries through comparative research method, elaborates in detail the situation of EU and China in electronic data evidence legislation, and carries out a comparative analysis of the similarities and differences between the Chinese and European legislation. It is found that the notarization system of civil law countries is characterized by strong state intervention, high authority of notarial acts, and wide scope of application; while the notarization system of common law countries is relatively flexible, with simple procedures but limited authority. EU legislation on electronic data evidence is centered on the General Data Protection Regulation (GDPR), which is detailed and has strong extraterritorial effect in protecting personal data rights. China has actively constructed a legal framework for electronic data evidence, focusing on combining it with national development strategies and reflecting Chinese characteristics while safeguarding data security and privacy. Based on this, the article puts forward suggestions in terms of technological upgrading, legislative optimization, professional development of personnel and international cooperation, with the aim of promoting the development of the notary system in the era of electronic data, and facilitating the effective use and protection of electronic data evidence.]]>
