公共云环境下的多租户数据隐私研究
Research on multi-tenant privacy preservation in public cloud environ-ment
摘要
Abstract
Considering the problem of unauthorized access and malicious attacks in multi-tenant application, a Multi-Tenant Privacy Protection Model(MTPPM)is presented using the lossless decomposition theory of relation database. The model can classify the least attributes according to attribute privacy constraint, and process the data with different anonymization approaches, and then achieve the balanced distribution through the disturbance of the data. It could also solve the problem of private information retrieval to protect user privacy by applying reconstruction method on the data. The theoretical analysis and experimental results show that the new model can provide efficient data privacy protection, and consider the requirements for the user under the trusted third party.关键词
