个人云存储用户的信息隐私感知威胁及应对策略研究

Research on Personal Cloud Storage Users'Information Privacy Perceived Threats and Coping Strategy

[目的/意义]泛在信息环境下,云内的共享性、个性化服务过程及泛在接入使得用户的隐私威胁不断加大,探索用户感知威胁的削弱因素及应对策略,将有助于解析泛在信息环境下用户自身复杂的信息保护行为,促进云存储服务的进一步发展和规模化应用。[方法/过程]结合心理学中的乐观偏差及应对理论,基于削弱因素——感知威胁——应对策略的研究逻辑,从乐观偏差、使用经验、官方认证3个维度分析对云存储用户感知威胁的不同影响,并验证乐观偏差对感知威胁到应对策略的调节作用。通过在线问卷调查,采用偏最小二乘法对结构模型进行估计。[结果/结论]研究发现,使用经验、乐观偏差负向影响感知威胁,而官方认证的作用并不显著。此外,乐观偏差会负向调节感知威胁与问题应对之间的关系,但不会影响其与情绪应对的关系。研究结果可有助于揭示云储存用户感知威胁与应对策略的发生规律及内在机理,并为云服务提供商的风险管控以及国家工信部门的监管政策提供建议和参考。

[Purpose/significance]Under ubiquitous information environment,the sharing of the cloud,personalized service process and ubiquitous access increase the privacy threat of users.Exploring the weaken factors on perceived threats of personal cloud storage users and their coping strategies will help to analyze users'complicated information protection action,and promote the further development and large-scale application of cloud storage services.[Method/process]Drawing upon the optimism bias and coping theories in psychology,based on the research logic"weaken factors→perceived threat→coping",we analyzed different influences on perceived threat of 3 factors(i.e.,optimism bias,prior experience and the official certification),and verified the moderating effect of optimism bias between perceived threats and coping behavior.Through the online questionnaire survey,we tested the model with the partial least square method.[Result/conclusion]The results reveal that prior experience and optimistic bias negatively affect perceived threat of cloud storage users,while official certification does not play a significant role.Besides,optimistic bias will be negative to adjust the relationship between perceived threat and emotion-focused coping,but will not affect the relationship between perceived threat and emotion-focused coping.The results help reveal the law and internal mechanism of personal cloud storage users'perceived threats and coping strategy,and provide advices and references for risk control of the cloud service providers and regulatory policies of Industry and Information Technology Ministry.
