社交媒体中的隐私:识别,缓解和应用

Privacy in Social Media: Identification, Mitigation and Applications

Ghazaleh Beigi, Huan Liu

摘要:

社交媒体的日益普及吸引了大量的人每天参加许多活动。这会产生大量丰富的用户生成数据。这些数据为研究人员和服务提供商提供了研究和更好地了解用户行为的机会,并进一步提高个性化服务的质量。发布用户生成的数据有暴露个人隐私的风险。社交媒体中的用户隐私是一个新兴的任务,近年来引起了越来越多的关注。这些作品从两个不同的角度研究了社交媒体中的隐私问题:识别漏洞和减轻隐私风险。最近的研究表明,用户生成的数据对两种一般类型的攻击,身份披露和属性披露的脆弱性。这些隐私问题要求社交媒体数据发布者在发布之前通过对用户生成的数据进行净化来保护用户的隐私。因此,已经提出了各种保护技术来匿名化用户生成的社交媒体数据。有大量的文献从许多角度对社交媒体中的用户隐私进行了研究。在本次调查中,我们回顾了社交媒体中用户隐私的主要成就。特别是,我们审查和比较国家的最先进的算法方面的隐私泄漏攻击和匿名化算法。我们从社交媒体的不同方面概述了隐私风险,并将相关工作分为五组:1)图形数据匿名化和去匿名化,2)作者身份识别,3)个人资料属性泄露,4)用户位置和隐私,以及5)推荐系统和隐私问题。我们还讨论了社会化媒体中用户隐私问题的开放问题和未来的研究方向。

英文摘要:

The increasing popularity of social media has attracted a huge number of people to participate in numerous activities on a daily basis. This results in tremendous amounts of rich user-generated data. This data provides opportunities for researchers and service providers to study and better understand users' behaviors and further improve the quality of the personalized services. Publishing user-generated data risks exposing individuals' privacy. Users privacy in social media is an emerging task and has attracted increasing attention in recent years. These works study privacy issues in social media from the two different points of views: identification of vulnerabilities, and mitigation of privacy risks. Recent research has shown the vulnerability of user-generated data against the two general types of attacks, identity disclosure and attribute disclosure. These privacy issues mandate social media data publishers to protect users' privacy by sanitizing user-generated data before publishing it. Consequently, various protection techniques have been proposed to anonymize user-generated social media data. There is a vast literature on privacy of users in social media from many perspectives. In this survey, we review the key achievements of user privacy in social media. In particular, we review and compare the state-of-the-art algorithms in terms of the privacy leakage attacks and anonymization algorithms. We overview the privacy risks from different aspects of social media and categorize the relevant works into five groups 1) graph data anonymization and de-anonymization, 2) author identification, 3) profile attribute disclosure, 4) user location and privacy, and 5) recommender systems and privacy issues. We also discuss open problems and future research directions for user privacy issues in social media.
