一种基于VCG机制的差分式隐私服务定价机制
A Pricing Mechanism of Differential Privacy Service with VCG Mechanism
摘要
Abstract
Data has many characteristics like various kinds,large quantity,high increment speed and low value density under the environment of big data.Meanwhile,computing resources can be wasted if all the privacy data be protected by the same kind of protection level.Therefore,privacy data must be protected in a hierarchical way.Since differential privacy is a strictly mathematical defined privacy preserve model which quantifies the level of privacy preserve based on probability theory,its parameter ε can be used to rank the levels of privacy preserve.A hierarchical privacy preserve service model has been proposed under the hypothesis that there already exists certain rank of the privacy preserve levels.The hierarchical service pricing mechanism in the model is composed of VCG mechanism and optimal matching theory,which make reasonable prices of every rank of services for users to choose reasonably.The prices for six levels of privacy preserve service have been established with this proposed mechanism.The results of analysis show that the pricing mechanism in the model proposed has widen the gap among all the six levels to fulfill the hierarchical privacy preserve service and to balance the allocation of social resources.关键词
