1. Foreword

1.1. Research background

The study of the legal boundary of data protection is an important and practical subject. With the rapid development of the Internet, big data and artificial intelligence technology, data protection has become a hot issue of global concern. The Chinese government attaches great importance to data protection, and has issued a series of laws and regulations to strengthen data security protection. This paper will discuss this issue in detail, in order to provide a useful reference for the study of the legal boundary of data protection. The legal boundaries of data protection need to be clearly defined. The legal boundary of data protection refers to which actions are legal and which actions are illegal in the process of data processing. The study of the legal boundary of data protection is of great significance for the formulation and improvement of data protection laws and regulations. In China, the legal boundary of data protection mainly involves the following aspects:
Protection of personal privacy rights. Personal privacy right is the core issue of data protection. In China, the right to personal privacy is protected by law, and no one can be infringed upon by any organization or individual. Therefore, the personal privacy rights must be fully respected and protected when processing the data. Legitimacy of data collection. Data collection is the premise of data protection. Only legal data collection can ensure data security. In China, data collection must comply with laws and regulations, follow the principles of legality, legitimacy and necessity, and must pass through the consent of the collected person [1]. Legitimacy of data use. Data use is an important link of data protection. Only only legitimate data use can ensure data security. In China, the use of data must comply with laws and regulations, follow the principles of legality, legitimacy and necessity, and must be authorized by the data controller. Security of data storage. Data storage is the key link of data protection. Only by ensuring the security of data storage can data leakage be prevented. In our country, data storage must comply with laws and regulations, follow the principles of safety and reliability, and must take necessary security measures. Legitimacy of data sharing. Data sharing is an important part of data protection. Only legal data sharing can ensure data security. In China, data sharing must comply with laws and regulations, follow the principles of legality, legitimacy and necessity, and must pass through the consent of the data controller and the shared person.
In conclusion, the legal boundaries of data protection are a complex and challenging subject. In China, the legal boundary of data protection mainly involves the protection of personal privacy right, the legitimacy of data collection, the legitimacy of data use, the security of data storage, the legitimacy of data sharing and so on. In order to better protect the data security, the Chinese government should strengthen the research on the legal boundary of data protection, formulate and improve the relevant laws and regulations, and strengthen the supervision of data processing activities. At the same time, data controllers and controlled persons should also strengthen self-discipline, enhance the awareness of data security protection, and jointly maintain data security [2].

2. The basic concept of data protection

2.1. Definition of data protection

Data protection is an increasingly concerned topic in today’s society. With the continuous development and popularization of Internet technology, the security issues of personal privacy information, important data and sensitive data have also become increasingly prominent. Therefore, data protection has become an important global issue, and governments and enterprises have formulated corresponding laws and policies to protect data security. This paper will explore in detail the definition of data protection and its legal boundaries. Data protection refers to the legal, safe and effective management and protection of the collection, storage, use, transmission, and disclosure of personal privacy information, important data and sensitive data [3]. Among them, personal privacy information refers to the personal identity, address, phone number, email and other personal identity information, important data refers to the national security, social stability, economic development has important influence of data, sensitive data refers to the national security, social stability, public interests, etc.
In terms of data protection, there are several legal boundaries to consider as described below:
Legitimacy of the data collection. Data collection must comply with the provisions of laws and regulations, and must be carried out with the consent of the collected person or as stipulated by law. For example, when collecting personal privacy information, the recipient must be informed of the use of the information and not beyond the necessary scope.Legitimacy of data use. The use of data must comply with the provisions of laws and regulations, and must be carried out with the consent of the user or stipulated by law. For example, after collecting personal privacy information, it must be used in accordance with the prescribed purpose and period, and shall not be leaked, tampered with, damaged, etc. Legitimacy of data transmission. Data transmission must comply with the provisions of laws and regulations, and must be carried out with the consent of the transmitted person or under the circumstances prescribed by law. For example, in the transmission of important data, the necessary security measures must be taken to prevent data leakage, tampering, damage, etc. Legitimacy of data disclosure. Data disclosure must comply with the provisions of laws and regulations, and must be conducted with the consent of the disclosures or the law. For example, when disclosing personal privacy information, the disclosed person must be informed of the use and protection measures of the information, and must not beyond the necessary scope. Technical boundaries of data protection. The technical boundary of data protection refers to what technical measures should be taken to ensure the security of data in the process of data protection. For example, when collecting personal privacy information, encryption technology should be used to ensure the confidentiality of information, and secure storage technology should be used to ensure the integrity of important data. Data protection is an important issue in today’s society, and its legal boundaries need to be fully considered. In terms of data protection, we must abide by the provisions of laws and regulations, and take the necessary technical measures to ensure the security of the data, so as to maintain the security of personal privacy information, important data and sensitive data [4].

2.2. The importance of data protection

The importance of data protection is increasingly prominent in the current society, which involves national security, social stability and citizens’ rights and interests. In the digital age, data has become an important resource of increasing value. However, the importance of data protection also means that data must be protected while being restricted and controlled, which involves the legal boundary of data protection. This paper will discuss the importance of data protection in detail, and focus on analyzing the legal boundary issues of data protection. Data protection is related to national security. In the digital age, data has become an important strategic resource with an increasing value. Therefore, the security of the data protection has become an important issue of national security. If the data is leaked or maliciously attacked, it will lead to the disclosure of state secrets, damage to economic interests and other problems, thus posing a threat to national security. Therefore, the issue of the legal boundary of data protection must be fully valued. Data protection is related to social stability. In the digital age, data has become an important social resource, and its application scope is increasingly extensive. However, the abuse and improper use of data can also pose a threat to social stability. For example, the use of personal privacy information for fraud, the use of false data for false publicity and other behaviors, will pose a threat to social stability. Therefore, the issue of the legal boundary of data protection must be fully valued. Data protection concerns citizens’ rights and interests. In the digital age, data has become an important civil right, and its application is increasingly extensive. However, the abuse and improper use of data can also violate civil rights. For example, the use of personal privacy information for illegal tracking and the use of false data for illegal investigation will infringe on citizens’ rights and interests. Therefore, the issue of the legal boundary of data protection must be fully valued. The legal boundary issue of data protection needs to be fully valued. In the digital age, the protection of data involves national security, social stability and civil rights, and its importance is self-evident. Therefore, the corresponding laws and regulations must be formulated to effectively protect and manage them. At the same time, it is also necessary to strengthen the research on the legal boundary issue of data protection to improve the legal level of data protection [5].

2.3. Basic principles of data protection

Data protection is an increasingly important issue in today’s society, involving personal information, privacy, security and other aspects. To ensure the validity and legitimacy of data protection, the basic principles of data protection are crucial. This paper will detail the basic principles of data protection and focus on the principles of legality, necessity, purpose specificity and minimum harm. The principle of legality refers to the compliance with relevant laws and regulations in the collection, processing and storage of data. This principle is the basis of data protection and a basic requirement for data processors to follow. The principle of legality requires that the data processor obtain prior consent of the individual with the collected data and comply with relevant laws and regulations, such as the EU General Data Protection Regulation (GDPR), during data processing. The principle of necessity means that in the collection, processing and storage of data, there must be clear, specific and legitimate purposes, and must ensure that the processing and use of data do not cause harm to personal privacy. The principle of necessity requires that the data processors must reasonably and appropriately process and use the data, and must take the necessary measures to protect personal privacy. The principle of necessity is the core of data protection and the basic requirement that data processors must abide by. The purpose-specific principle is ensuring in collecting, processing, and storage that data processing and use is limited to the original purpose and that it must not be abused or used for other purposes. The purpose-specific principle requires that the data processors must reasonably and explicitly process and use the data, and must take the necessary measures to prevent the abuse or improper use of the data. The minimum harm principle is that the necessary security and protection measures must be taken to collect, process and store data to minimize the risk of data leakage, destruction or loss. The minimum damage principle requires that the data processors must take the necessary security measures, such as encryption, access control, etc., to protect the confidentiality, integrity, and availability of the data. The minimum damage principle is the key to data protection and a basic requirement that data processors must follow.
In conclusion, the basic principles of data protection include the principles of legality, necessity, purpose specificity and minimum harm. These four principles complement each other and form the basis and core of data protection. Data processors must strictly abide by these principles, ensure the legitimacy and security of data processing activities, and protect personal privacy and data value [6].

3. The legal framework for data protection

3.1. Overview of China’s data protection legal system

With the rapid development of technologies such as the Internet, big data and artificial intelligence, the protection of personal information has become an important global issue. The Chinese government attaches great importance to data protection, and has gradually established a complete set of legal system for data protection.
First of all, China’s data protection legal system mainly includes the Network Security Law, the Personal Information Protection Law and other laws and regulations. Among them, the "Network Security Law" is China’s first law specifically for network security issues, clarifying the basic principles, basic tasks and basic systems of network security, providing a legal basis for data protection work. The "Personal Information Protection Law" provides detailed provisions on the protection of personal information, including the collection, use, storage, deletion of personal information and other links, to protect the legitimate rights and interests of personal information. Secondly, China’s data protection legal system also includes a series of departmental regulations and normative documents. For example, the relevant provisions in the Cyber Security Law involve data security, cross-border data transmission, data backup and recovery, and many other aspects. In addition, the implementation of the Personal Information Protection Law also requires governments at all levels and relevant departments to formulate corresponding implementation rules and specific operational norms, and further clarify the specific requirements of data protection work [7]. In addition, China’s data protection legal system also includes the coordination of international law and domestic legislation. In the context of globalization, China’s data protection legal system needs to be in line with international laws and draw lessons from the advanced international experience. At the same time, it should also take into account the actual situation of domestic data protection and formulate a legal system for data protection in line with national conditions. In general, China’s data protection legal system has formed a complete set of legal system, providing a strong legal guarantee for the data protection work. However, with the development and application of new technologies, the data protection legal system also needs to be constantly improved and adjusted to meet the new data protection needs.

3.2. Overview of the international data protection legal system

Data protection is one of the important legal issues facing today’s society, which involves the collection, storage, use, transmission and protection of personal information. The International Data Protection Legal System is an important legal framework designed to protect personal privacy and data security. This section will detail an overview of the international data protection legal system, including the laws and regulations included in the international data protection legal system and its reference significance for global data protection.
The international data protection legal system includes the EU General Data Protection Regulations (GDPR), the California Consumer Privacy Act (CCPA) and other laws and regulations. Among them, the GDPR is a data protection law enacted by the European Union, which came into effect on 25 May 2018, and aims to protect the privacy rights and data security of EU citizens. The GDPR stipulates the collection, use, storage, transmission and deletion of personal data, and sets strict standards and procedures for data protection. The implementation of GDPR has had a profound impact on global data protection, and provides a useful reference for other countries and regions to formulate data protection laws. CCPA is A data protection law enacted by California that came into effect on November 1,2018, aiming to protect the privacy rights and data security of California residents. CCPA provides for regulations on the collection, use, sharing and sale of personal data, and sets up strict standards and procedures for data protection. The implementation of CCPA has had a positive impact on global data protection, and provides a useful reference for other countries and regions to formulate data protection laws [8]. In addition to the GDPR and CCPA, the international data protection legal system also includes other laws and regulations, such as the European Convention on Human Rights (ECHR), the European Privacy Directive (GDPR), etc. The ECHR is a data protection law enacted by the European Court of Human Rights and sets out the basic principles and standards for personal privacy and data protection. The GDPR is a data protection law enacted by the European Commission, which stipulates the collection, use, storage, transmission and deletion of personal data, and sets strict standards and procedures for data protection. These laws and regulations provide a useful reference for global data protection.
The international data protection legal system includes the EU General Data Protection Regulations, the California Consumer Privacy Law and other laws and regulations, which provides a useful reference for the global data protection. These laws and regulations provide a useful reference for global data protection, help to protect personal privacy and data security, and provide a useful reference for other countries and regions to formulate data protection laws [9].

3.3. The development trend of the legal framework for data protection

With the rapid development of digitalization and informatization and the advancement of globalization, data has become an important factor of production and strategic resource. Data protection has become a global issue, countries are strengthening data security protection, protect the privacy of citizens. The development trend of the legal framework for data protection mainly includes the following aspects:
Strengthen data security protection: Data security protection is the core content of the legal framework of data protection. In the current context of digitalization and informatization, data security problems are becoming more and more prominent, such as hacker attacks, data leakage, data abuse and so on. Therefore, strengthening data security protection is an important trend in the development of the legal framework of data protection.
Improve the legal system for data protection: The development of the legal framework for data protection needs to be continuously improved and strengthened. Countries should, according to their own actual conditions, formulate and improve the legal system of data protection, strengthen the supervision and management of data protection, and improve the efficiency and effect of data protection. At the same time, international cooperation on data protection should be strengthened to promote the establishment and improvement of the global legal system for data protection.
Strengthen the awareness of data protection: The awareness of data protection is an important factor in the development of the legal framework of data protection. In the context of digitalization and informatization, people are more and more dependent on data, and pay more and more attention to data protection. Therefore, the publicity and popularization of data protection awareness should be strengthened to improve the public’s awareness and understanding of data protection, so as to promote the development of the legal framework of data protection [10].

4. Strengthen the research on data protection technology

Data protection technology is an important support for the development of the legal framework of data protection. Under the background of digitalization and information, the research and application of data protection technology is more and more important. Countries should strengthen the research and development of data protection technologies to improve the efficiency and effect of data protection, so as to promote the development of the legal framework of data protection. To sum up, the development trend of data protection legal framework mainly includes strengthening data security protection, improving the legal system of data protection, strengthening data protection awareness, strengthening data protection technology research and other aspects. Only by strengthening data protection can we effectively protect citizens’ privacy and promote the development and progress of society.

4.1. Research status of the legal boundary of data protection

Research on data protection legal boundaries originated in Europe and originated from concerns about legal issues such as personal information and privacy. In the information age, data has become an important factor of production, and its protection problem has gradually attracted people’s attention. With the rapid development of the Internet, big data, artificial intelligence and other technologies, the way, scope and quantity of data are used have changed greatly, which brings new challenges and problems to data protection. The main contents of the legal boundary research of data protection include the laws and regulations of data protection, the technical means of data protection, and the ethical and legal issues of data protection. Among them, laws and regulations are the basis of data protection, involving personal information protection Law, data Protection Law, network security Law and other laws and regulations. These laws and regulations provide legal basis and norms for data protection, and provide guidance and guarantee for the implementation of data protection. In addition, the technical means of data protection is also an important part of the data protection legal boundary research. With the increasing importance of data protection, the technical means of data protection have also been widely concerned and applied. For example, data encryption, data desensitization, data watermark and other technical means, can effectively protect the privacy and security of data, prevent data leakage and abuse. The ethical and legal issues of data protection are also the important contents of the legal boundary research of data protection. The ethical and legal issues of data protection involve personal privacy, commercial secrets, public interest and so on. In the process of data protection, the interests of all parties are needed to be balanced to ensure the rational use and protection of the data. At the same time, it is also necessary to strengthen the legal supervision, strengthen the law enforcement of data protection, and improve the level of legal guarantee of data protection.
In short, the legal boundary research of data protection is a research topic involving multiple fields and multiple levels, which needs to comprehensively consider multiple factors of law, technology, ethics, and business. With the increasing importance of data protection, the legal boundary research of data protection has also received more and more attention and research. In the future, with the continuous development and progress of data protection technology, the research of data protection legal boundary will continue to deepen and improve.

4.2. Main contents of the research on the legal boundary of data protection

It is an important research field, involving many aspects, such as data classification, cross-border data transmission, and data security. This paper will discuss in detail from these aspects. Data classification is an important part of the study of data protection legal boundary. Data classification refers to the process of classifying and managing data in order to better protect data security and privacy. Data classification needs to take into account the sensitivity, use and storage location of the data, so as to take corresponding protection measures. In terms of data classification, the data subject has the right to choose whether to disclose its personal information, and has the right to request the modification and deletion of its personal information. At the same time, the data controller has the responsibility to ensure that the data classification and protection of the data comply with the relevant laws and regulations [11].
Cross-border data transmission is also an important part of the legal boundary research of data protection. With the development of globalization, the cross-border transmission of data has become an irreversible trend. However, the cross-border transmission of data also poses many legal and security issues. Cross-border transmission of data requires compliance with relevant data protection laws and regulations, including the rights and obligations of data subjects, the responsibilities and obligations of data controllers, and the legality and security of cross-border data transmission, etc. In addition, the cross-border transmission of data also needs to consider the will and consent of the data subject, as well as the relevant laws and regulations. Data security is also an important part of data protection legal boundary research. Data security refers to measures taken to protect data from access, tampering, theft, and destruction by unauthorized personnel. Data security needs to take into account the storage, transmission, processing and use of data, and needs to take corresponding technical and security measures [12]. In terms of data security, the data subject has the right to require the personal information to be protected, and has the right to require the personal information to be modified and deleted. At the same time, the data controller has the responsibility to ensure the security and privacy of the data and take necessary security measures to prevent data leakage and attacks. It is an important research field, involving many aspects, such as data classification, cross-border data transmission, and data security. Data classification needs to consider factors such as the sensitivity, use and storage location of the data, so as to take corresponding protection measures. Cross-border transmission of data requires compliance with relevant data protection laws and regulations, and takes into account the will and consent of the data subject, as well as relevant laws and regulations. Data security requires the corresponding technical and security measures to protect the data from unauthorized personnel access, tampering, theft, destruction and so on.

4.3. Methods and techniques of legal boundary research of data protection

With the improvement of data protection awareness and the continuous progress of technology, the research on the legal boundary of data protection will also continue to develop, and the future research will develop in the direction of data classification, data cross-border data transmission, data security and so on. Data classification is an important direction for the future data protection legal boundary research. Data classification refers to the classification, classification, identification and management of data to meet the requirements of data security and privacy protection. Data classification can help enterprises and organizations to better manage and protect their data, and reduce the risk of data leakage and abuse. In the future, the research on data classification will be more thorough, involving the standards, methods, technologies and other aspects of data classification [20]. Cross-border data transmission is another important research direction. With the development of globalization, cross-border data transmission is becoming more and more common, but it also brings problems such as data security and privacy protection. In the future, the research on cross-border data transmission will pay more attention to the transmission rules, security mechanism, privacy protection and other issues, so as to ensure the security and legitimacy of cross-border data transmission. Data security is an important direction of the future data protection legal boundary research. Data security means to protect the data from unauthorized access, leakage, damage and other risks. As the problem of data security becomes increasingly prominent, the research of data security will become more important. In the future, the research on data security will pay more attention to data security technology, security strategy, security supervision and other issues, in order to improve the level of data security.
In the future, the research of data protection will develop towards data classification, data cross-border transmission, data security and other directions. The in-depth research of these research directions will help to improve the legal framework of data protection, guarantee the security and legitimacy of data, and promote the development of data science.

7. The conclusion

The study of data protection legal boundary refers to the balance between data protection and privacy protection, exploring the legitimacy and rationality of data use and protection, as well as the legal and regulatory framework of data security protection. In this area, the rights and responsibilities of data users and the legal restrictions and provisions for data protection are needed to be considered. The study of data protection legal boundary is of great significance to the data protection practice in China. With the development of Internet and big data technologies, data collection, storage, use and transmission have become increasingly important, and research on the legal boundaries of data protection can help us better understand the legal and regulatory framework of data use and protection and how to balance the interests between data users and data protection agencies. In the future, it is necessary to strengthen data security protection and improve the data protection legal system. Data security is one of the core issues in the legal boundary research of data protection. With the frequent occurrence of data leakage and attacks, data security protection measures, such as encryption, access control and data backup. At the same time, it is necessary to strengthen the improvement of the legal system of data protection, such as formulating stricter laws and regulations, strengthening data protection supervision and enhancing the public’s awareness of data protection.
