## 2 Literature Review  
In recent years, scholars in the fields of Information Science and Library Science and Medical Informatics in China and abroad have carried out a series of studies on privacy disclosure intentions and behavior, mainly focusing on mobile applications, social media, e-commerce, and Internet medical services. (1) Mobile applications. The research in this scenario mainly focuses on analyzing the influencing factors of mobile application user privacy disclosure willingness and relevant information behaviors. From the perspective of emotional attitude, [PERSON] et al. proposed the concept of \"privacy fatigue\" and believed that the privacy disclosure willingness of mobile application users is affected by a combination of privacy fatigue, privacy concerns, and user personal characteristics [24]. Scholars such as [PERSON] found that user internal satisfaction (such as entertainment, escapism) and social satisfaction (such as social communication) also affected their willingness to disclose private information [25]. In addition, [PERSON] and other scholars investigated the privacy policy of mobile applications. Their research showed that certain mobile applications continue to track and share private user data when they are not in use, which clearly violates the privacy policy provided to users and would have a negative impact on user privacy disclosure behavior [26]. (2) Social media. Certain scholars analyzed the influencing factors of social media user privacy disclosure willingness and behavior from different perspectives. [PERSON] et al. conducted research from the perspective of information systems and concluded that the system quality, service quality, and information quality of social networking sites have a positive impact on user willingness to disclose personal location-related information (PLRI) [27]. From the perspective of sociology, [PERSON] et al., [PERSON] et al., and other scholars analyzed the privacy disclosure willingness of social networking site users with social exchange theory and trust theory. Factors such as trust in social networking sites and other social networking site users, potential social rewards, and the \"supportive atmosphere\" constructed by online social support such as emotion, information, respect, etc., had a positive impact on user willingness to disclose private information [28; 29]. Scholars such as [PERSON] and [PERSON], [PERSON] et al., and [PERSON] et al. found that users' perceived usefulness, perceived enjoyment, perceived risk, and platform rewards all affect social media user willingness to disclose private information [30; 31; 32]. On the other hand, scholars such as [PERSON] et al. explored the behavior patterns and formation mechanism of the privacy disclosure behavior of social media users. They defined two behavioral modes, i.e., voluntary sharing and mandatory provision. Voluntary sharing refers to the active personal privacy disclosure behavior of users, which is mainly affected by positive factors such as perceived benefits, social network scale, and personalized services. Mandatory regulations refer to platformsthat force users to disclose personal information, which is mainly affected by negative factors such as age, privacy policy, and perceived risk [33]. (3) E-commerce. Various scholars have attempted to develop technical solutions to resolve the contradiction between user data collection and user privacy protection in e-commerce companies. [PERSON] et al. designed an information technology solution called the \"negotiation, active-recommendation privacy policy application\", and confirmed, through experiments, that the program could help companies resolve the contradiction between user data collection and privacy protection, reduce user privacy concerns, and increase user willingness to disclose privacy and actual disclosure behavior [34]. Various scholars also analyzed the potential influencing factors of e-commerce user privacy disclosure behavior.
