智慧城市下基于属性加密的隐私数据保护

A privacy protection scheme based on attribute encryption in smart cities

智慧城市中涉及的数据涵盖了人们的个人信息、位置数据、交通数据等敏感信息。为了满足智慧城市中的数据共享和隐私保护需求,结合属性基可追踪加密技术,为智慧城市的隐私数据保护提供一种新的解决方案并详细介绍了方案的构成。根据属性来细粒度地控制不同用户对数据的访问权限,有效提高隐私数据的安全性。

The data involved in smart cities covers sensitive information such as people’s personal information,location data,and traffic data.In order to meet the needs of data sharing and privacy protection in smart cities,this paper provides a new solution for privacy data protection in smart cities with attribute-based traceable encryption technology and introduces the composition of the solution in detail.According to attributes to fine-grained control of different users to the data access rights,effectively improve the security of private data.
