Research on Evolutionary Game Strategy of Digital Platform Privacy Protection Behavior Driven by Blockchain Technology
The digital platform provides a free and open online service space for people to communicate and share information.However,due to the contradiction between privacy disclosure and privacy security,the privacy of users is severely challenged in the process of mining user information.If personal privacy is leaked,it will cause immeasurable damage and inconvenience to the users,and the platform will also suffer reputation loss and economic losses.It is difficult for traditional technologies to effectively solve the problems of data security sharing and information backtracking on digital platforms.Blockchain has the characteristics of asymmetric encryption,distributed ledger,immutable,and information traceability,which can meet the growing requirements of data privacy protection on digital platform.Therefore,the transformation from the digital platform with traditional model to the platform model driven by blockchain technology will be a breakthrough to solve the contradiction between the frequent privacy disclosure incidents and the continuous awakening of people's privacy awareness.This paper uses evolutionary game theory to consider digital platforms and users separately with regarding digital platform operators and user groups as two game decision-making subjects.Meanwhile,taking into account government regulation factors and the assumption of evolutionary game bounded rationality,the paper constructs the privacy protection behavior policy models of the platform and users in the blockchain environment and the traditional environment respectively,analyzes the dynamic evolution process of the optimal choice of the privacy protection behavior strategy of the two parties.In addition,Matlab software is used to conduct numerical simulation experiments in order to explore the optimal decision-making strategy selection of the digital platform and users'respective privacy protection behaviors.The key findings of this paper show that the choice of the optimal strategy of the two parties in the privacy protection game is closely related to the total cost of privacy protection,the additional benefits obtained by the platform using blockchain,the added benefits of users,the value benefits of users,the total loss of privacy disclosure,the loss bearing coefficient of the platform,the trust level of users on the platform and the intensity of the government's regulatory penalties,etc.When the above related parameters change,the following three evolutionary stable strategy combinations could be generated:{ choose traditional approach for privacy protection,do not disclose private information },{ choose traditional approach for privacy protection,disclose private information } and { choose blockchain for privacy protection,disclose private information}.Furthermore,through numerical simulation analysis,the research conclusion includes:the platform's strategy selection is affected by the cost,loss and benefit of the use of blockchain technology;the user's strategy selection is influenced by both the actual benefits and actual losses of blockchain use;the intensity of the government's regulatory penalties will affect the digital platform's choice of blockchain use strategy.The research innovation contributions of this paper are the followings:the paper combines the perspectives of technology and management in order to explore the management problem driven by technology.It not only extends the traditional game theory model which adds the blockchain application scenario but also expands the boundaries of the related fields of blockchain related to the privacy protection behavior of digital platform.The main management implications include:blockchain technology can effectively reduce the input cost of platform privacy protection and positively improve the revenue.It can effectively reduce the potential risk of platform privacy disclosure and improve the privacy protection efficiency.It can reasonably improve the revenue from user privacy disclosure and enhance the user stickiness of the platform.It can give full play to the government's regulatory restraint role and effectively enhance the government's social influence.The research results of this paper can provide theoretical model reference for relevant researchers,and also provide decision-making reference for platform enterprises and government.
