Abstract

In a distributed digital identity system, there are various types of credential storage entities. With the development and popularization of distributed digital identities, data silos have emerged among multiple credential storage entities. To break this dilemma, this paper designs a distributed digital identity private sharing method based on an efficient Random 1-out-of-n OT extension protocol. The method uses the data obfuscation algorithm constructed by Permutation-based Hashing to design a two-party private data sharing protocol, which outputs the intersection of private data sets to the two parties. After experimental analysis, on a scale of ten million data, this method can better meet the needs of the real world.
