Abstract
Blockchain is an effective solution for data sharing. The usual practice is to write metadata and the hash of raw data to the blockchain. This design does not take the confidentiality of metadata into account. The data provider wants to freely decide whether to share data through the data applicant’s search conditions, without exposing what data they have. This paper presents a Cross-Domain data security sharing model called DUMPLING, which is based on consortium blockchain. It achieves trusted data transaction evidence and privacy protection search. Analysis shows that the system has good security and efficiency.
