Study finds releasing individual ballots in elections exposes less than 0.2% of voters' choices.
《科学进步》的一项新研究审查了在选举中公布个人选票的隐私风险。 A new study in Science Advances examines the privacy risks of releasing individual ballots in elections. 研究人员分析了2020年亚利桑那州马里科帕县的选举结果,发现公布个人选票将暴露不到选民选择的五分之一,而目前按选区报告总结果的方法则保护了99.95%的选民身份。 Analyzing the 2020 Maricopa County, Arizona, election, researchers found that releasing individual ballots would expose less than a fifth of a percent of voters’ choices, while the current method of reporting aggregate results by precinct protects 99.95% of voters' identities. 该研究强调在显示投票选择方面风险很小,但指出,更积极的数据发布不会大大增加接触风险。 The study highlights a small risk in revealing vote choices but suggests that more aggressive data releases do not significantly increase exposure.
