Abstract: The rapid advancement of information technology has led to the widespread adoption of mobile healthcare services, greatly enhancing the convenience of medical experiences. However, this progress has also posed a significant challenge to user privacy security. Addressing these challenges, this study employs evolutionary game theory to explore the behavioral strategies and evolution for users, mobile healthcare service providers and the government. Specifically, it aims to reveal their interactions and influences in terms of privacy protection. To begin with, this study theoretically analyzes the optimal strategies for users, service providers and the government. Subsequently, numerical simulations are conducted to assess the impact of various factors on strategy selection and create three insights.
Firstly, in the digital age, users must heighten their awareness of personal information and privacy security. When utilizing service platforms, users must remain vigilant to the risks of personal information leakage and take proactive measures, such as reporting to the government and assisting in governance, upon privacy infringement. This proactive approach to rights protection not only safeguards individual interests but also contributes to the societal privacy protection mechanism. Furthermore, the rights protection behavior of users can serve as an inspiration for others to join the actions, collectively defending lawful rights. Notably, user behavior significantly influences government regulatory strategies. If users relinquish their rights, the government may resort to passive regulation, leading to ineffective containment of privacy leakage issues. Conversely, active rights protection by users can strengthen government regulation, thereby better ensuring privacy security.
Secondly, when service providers are inclined to adopt strategies that could result in data leakage, users become more cautious and are likely to engage in rights protection actions. The combined effects of user rights protection and government regulatory strategies increase the risk of service providers penalized for privacy breaches. Consequently, service providers, considering the legality and compliance of their actions, may prefer to choose the lower-risk ‘data self-use’ strategy. In the digital era, data security is a crucial component of corporate competitiveness. Service providers must ensure that their data management and protection capabilities adequately safeguard user privacy. Effectively controlling privacy leakage risks not only enhances user trust but also prevents legal and financial repercussions. Therefore, ‘data self-use’ emerges as a pivotal strategy for service providers in the competitive market.
Lastly, when users tend to abandon their rights, the government may adopt a passive regulatory stance, allowing service providers to exploit regulatory gaps and leak data. To address this, the government should motivate users to actively protect their rights and participate in regulation and governance. One effective approach is to establish reward mechanisms that encourage users to report privacy leaks. Enhancing regulatory efficiency is crucial to constraining service provider behavior, making them more inclined to opt for the ‘data self-use’ strategy. Additionally, the government’s regulatory costs also affect its strategy choices. As regulatory mechanisms improve, the costs of active regulation decrease, prompting the government to favor active regulation. To ensure effective protection of user privacy rights, the government should continuously evaluate and adjust its regulatory strategies.
