他们对我了解多少？在线行为档案的内容和关注点
What do they know about me? Contents and Concerns of Online Behavioral Profiles
摘要：
数据聚合器收集有关个人用户的大量信息，并创建详细的个人在线行为档案。行为概况通过改进产品和服务使用户受益。然而，他们也对用户隐私、收集做法的透明度和个人资料中数据的准确性提出了关切。为了提高透明度，一些公司允许用户访问他们的行为资料。在这项工作中，我们调查了用户的行为配置文件，利用这些访问机制。使用面对面访谈（n=8），我们分析了配置文件中显示的数据，引起用户的关注，并估计配置文件的准确性。我们通过在线调查（n=100）证实了我们的访谈结果。为了评估提高透明度的说法，我们将个人资料中显示的数据与公司拥有的用户数据进行了比较。超过70%的参与者对信用和健康信息等敏感数据的收集、详细程度以及如何使用这些数据表示担忧。我们发现，简介中显示的数据与公司拥有的数据之间存在很大差距。大量的配置文件是不准确的，高达80%的不准确性。我们讨论公共政策管理的影响。
英文摘要：
Data aggregators collect large amount of information about individual users and create detailed online behavioral profiles of individuals. Behavioral profiles benefit users by improving products and services. However, they have also raised concerns regarding user privacy, transparency of collection practices and accuracy of data in the profiles. To improve transparency, some companies are allowing users to access their behavioral profiles. In this work, we investigated behavioral profiles of users by utilizing these access mechanisms. Using in-person interviews (n=8), we analyzed the data shown in the profiles, elicited user concerns, and estimated accuracy of profiles. We confirmed our interview findings via an online survey (n=100). To assess the claim of improving transparency, we compared data shown in profiles with the data that companies have about users. More than 70% of the participants expressed concerns about collection of sensitive data such as credit and health information, level of detail and how their data may be used. We found a large gap between the data shown in profiles and the data possessed by companies. A large number of profiles were inaccurate with as much as 80% inaccuracy. We discuss implications for public policy management.
