基于数据敏感性的大数据访问控制模型研究
Research on Big Data Access Control Model Based on Data Sensitivity
摘要
Abstract
Recent growth in big-data is raising security and privacy concerns. Traditional access control models cannot provide dynamic access control to massive data. In view of the data security problem of Hadoop platform, a content sensi-tivity based access control model is proposed. The model enhances access control policies by harnessing the data context, usage patterns, and data sensitivity. The proposed model evaluates data sensitivity with minimal user intervention and adjusts access control strategies based on changes in data sensitivity caused by data set additions and deletions. Experi-mental results show that the proposed model is capable of enforcing access control policies on non-multimedia data sets with minimal overhead and overcomes the disadvantage on lacking of security about existing access control model in Hadoop platform.关键词
