从身份验证问题到公共社交事件：Twitter上生日分享的特征
From an Authentication Question to a Public Social Event: Characterizing Birthday Sharing on Twitter
摘要：
出生日期（DOB）历来被认为是私人信息，可以安全地用于身份验证，但近年来已经转向广泛的公共共享。在这项工作中，我们描述了现代社交媒体用户如何在网上公开分享生日祝福。在45天的时间里，我们收集了超过280万条祝72.4万个Twitter账户生日快乐的推文。对于5万个账户，他们的年龄可能会透露他们的出生日期，10%是受保护的账户。我们的调查结果显示，大多数公共和受保护的帐户似乎都接受他们的生日和DOB被他们的朋友在网上透露，即使他们没有在他们的个人资料中列出。我们通过一项调查进一步补充了我们的发现，以衡量人们对DOB披露问题的认识以及人们如何看待分享不同类型的生日相关信息。我们的分析表明，在线给别人生日祝福被认为是一种庆祝活动，许多用户对此感到非常舒服。这种观点与安全领域的趋势相吻合，在安全领域，在身份验证过程中使用DOB不再被认为是最佳实践。
英文摘要：
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.
