Abstract

The invention discloses a privacy protection method orienting data sharing. The privacy protection method comprises the following steps of sending a sharing request to a data owner by a requester; selecting a shared data set by the data owner, carrying out estimation and judgment on the requester according to a trust model, and calculating privacy information content of the selected shared data set; judging whether the requester can obtain the shared data set according to a trust estimation result, and if not, selecting data from an alternative bank to replace the shared data set until the data can be shared. Therefore, the user-centered privacy protection method based on trust and replacement is realized, the privacy data safety is protected and the data sharing availability is improved in data sharing application.

Description

technical field [0001] The invention relates to a privacy protection method data storage system, in particular to a privacy data protection method for application in data sharing, which belongs to the field of computer security. Background technique [0002] With the continuous development of the information age, the exchange of information between different departments and regions has gradually increased, and the development of computer network technology has provided a guarantee for information transmission. Realizing data sharing can enable more people to use existing data resources more fully, reduce duplication of data collection, data collection and corresponding costs, and focus on developing new applications and system integration. But at the same time, in network data sharing applications, from the perspective of privacy protection, entities do not want to share all data with each interactive entity, but selectively share it. [0003] The currently widely used meth...
