摘要 针对社交发现服务中的隐私保护问题,提出一种位置隐私保护社交模型。通过将用户数据分成索引消息和数据消息,使得地理坐标和位置数据解耦,引入多授权中心环境下的属性基加密方法(attribute based encryption,ABE)对索引消息进行加密,位置数据由对称加密后上传,两者分别保存在索引服务器和数据服务器的个人存储空间上。分析表明,模型支持陌生成员发现和群组管理功能,灵活性高,能够保护用户的社交隐私数据,可以很好地用于社交发现服务。

英文摘要 This paper proposed a social discovery service model aimed to protect location privacy. The model divided user’s data into index message and data message in order to separate location coordinates from location data, adopted multi-authority attribute based encryption method to encrypt index message and encrypted location data by symmetric encryption method. The analysis indicates that the model is both flexible on supporting stranger discovery and group management, and good at protecting social privacy, so it can be applied very well to social discovery service.
英文关键词 social network; location-based service(LBS); privacy protection; attribute-based encryption
