我们系统地回顾了在国家公共卫生统计与信息系统协会（NAPHSIS）列出的基于web的数据查询系统中发布汇总数据所采用的统计披露控制技术。对每个基于web的数据查询系统进行检查，以确定(1)是否采用了任何类型的细胞抑制，(2)是否使用了次级细胞抑制，以及(3)是否可以计算抑制的细胞计数。每个系统花费的时间不超过30分钟。在审查的35个系统中，超过一半（n= 18）未观察到抑制；在2个地点观察到低于阈值的计数；抑制值在9个站点恢复。六个网站有效地抑制了小计数。这项调查揭示了在包含敏感公共卫生数据的数据查询系统中使用的保护措施存在重大缺陷。许多系统没有使用任何披露控制，而且绝大多数使用的系统不一致或不充分地部署了它。
We systematically reviewed the statistical disclosure control techniques employed for releasing aggregate data in Web-based data query systems listed in the National Association for Public Health Statistics and Information Systems (NAPHSIS). Each Web-based data query system was examined to see whether (1) it employed any type of cell suppression,(2) it used secondary cell suppression, and (3) suppressed cell counts could be calculated. No more than 30 minutes was spent on each system. Of the 35 systems reviewed, no suppression was observed in more than half (n= 18); observed counts below the threshold were observed in 2 sites; and suppressed values were recoverable in 9 sites. Six sites effectively suppressed small counts. This inquiry has revealed substantial weaknesses in the protective measures used in data query systems containing sensitive public health data. Many systems utilized no disclosure control whatsoever, and the vast majority of those that did deployed it inconsistently or inadequately.
