在本文中，我们提出了一个联邦在线社交网络（OSN），专注于用户隐私和数据的可用性。所有用户内容都在最终用户设备上加密和解密，从而对OSN提供商隐藏内容。通过采用新颖的别名方法并使用用于相互友谊建立的安全算法，对OSN提供商隐藏社交图。用户名被映射到朋友特定的别名，这减少了提供程序通过分析这些标识符可以收集的信息量。用户相互进行身份验证，而不会向潜在的攻击者透露他们的身份。所提出的系统允许独立OSN提供商之间的用户交互。为了提高数据的可用性，我们使用了一个复制方案，它不会危及社会图的混淆。我们的方法不同于现有的作品，主要是由社会图混淆与复制相结合。
In this paper we propose a federated online social network (OSN) which focuses on user privacy and data availability. All user content is encrypted and decrypted on end-user devices, hiding the content from the OSN providers. The social graph is hidden from the OSN provider by employing a novel aliasing approach and using secure algorithms for mutual friendship establishment. Usernames are mapped to friend-specific aliases, which reduces the amount of information a provider can gather from analyzing these identifiers. Users authenticate to each other without revealing their identities to a potential attacker. The proposed system allows for user interactions between independent OSN providers. To improve data availability we use a replication scheme which does not jeopardize the obfuscation of the social graph. Our approach differs from existing works mainly by the social graph obfuscation in combination with replication.
