论文摘要
从历史上看，出生日期（DOB）被认为是私人信息，可以安全地用于身份验证，但是近年来已经向广泛的公众共享转变。在这项工作中，我们表征了现代社交媒体用户如何在线公开分享生日愿望的方式。在45天的时间里，我们收集了超过280万的推文，希望生日快乐，向724K Twitter帐户收集。对于50k帐户，他们的年龄很可能被提及透露他们的DOB，而10％的人受到保护。我们的发现表明，大多数公共和受保护的账户似乎都接受了他们的生日和DOB，即使他们的朋友在网上揭示了他们的生日，即使他们没有在个人资料上列出。我们通过一项调查进一步补充了我们的发现，以衡量对DOB披露问题的认识以及人们如何思考分享不同类型的生日相关信息。我们的分析表明，在线向他人提供生日愿望被认为是庆祝活动，许多用户对此非常满意。该观点与在安全性中使用DOB在身份验证过程中不再被视为最佳实践的安全性趋势相匹配。
Date of birth (DOB) has historically been considered as private information and safe to use for authentication, but recent years have seen a shift towards wide public sharing. In this work we characterize how modern social media users are approaching the sharing of birthday wishes publicly online. Over 45 days, we collected over 2.8M tweets wishing happy birthday to 724K Twitter accounts. For 50K accounts, their age was likely mentioned revealing their DOB, and 10% were protected accounts. Our findings show that the majority of both public and protected accounts seem to be accepting of their birthdays and DOB being revealed online by their friends even when they do not have it listed on their profiles. We further complemented our findings through a survey to measure awareness of DOB disclosure issues and how people think about sharing different types of birthday-related information. Our analysis shows that giving birthday wishes to others online is considered a celebration and many users are quite comfortable with it. This view matches the trend also seen in security where the use of DOB in authentication process is no longer considered best practice.
