面向用户数据共享决策和理解的有效差分隐私通信

Towards Effective Differential Privacy Communication for Users' Data Sharing Decision and Comprehension

Aiping Xiong, Tianhao Wang, Ninghui Li, Somesh Jha

摘要:

差分隐私通过在聚合级别(DP)或个体级别(LDP)上扰乱数据来保护个体的隐私。我们报告了四个在线人类受试者实验,研究在健康应用程序数据汇集设置中使用不同方法向外行传达差分隐私技术的影响。实验1和实验2考察了当给予不同的DP或LDP描述时,参与者对低敏感和高敏感个人信息的数据披露决策。实验3和实验4揭示了参与者数据共享决策背后的原因,并考察了参与者对这些DP或LDP描述的主观和客观理解。当显示的描述,解释的含义,而不是DP或LDP技术的定义/过程,参与者表现出更好的理解,并表现出更多的愿意与LDP比DP共享信息,表明他们的理解LDP的更强的隐私保证相比DP。

英文摘要:

Differential privacy protects an individual's privacy by perturbing data on an aggregated level (DP) or individual level (LDP). We report four online human-subject experiments investigating the effects of using different approaches to communicate differential privacy techniques to laypersons in a health app data collection setting. Experiments 1 and 2 investigated participants' data disclosure decisions for low-sensitive and high-sensitive personal information when given different DP or LDP descriptions. Experiments 3 and 4 uncovered reasons behind participants' data sharing decisions, and examined participants' subjective and objective comprehensions of these DP or LDP descriptions. When shown descriptions that explain the implications instead of the definition/processes of DP or LDP technique, participants demonstrated better comprehension and showed more willingness to share information with LDP than with DP, indicating their understanding of LDP's stronger privacy guarantee compared with DP.
