Big data oriented ownership confirmation method

Abstract

The invention discloses a big data oriented ownership confirmation method. An ownership confirmation process comprises an initialization phase, a sampling challenge phase and an ownership confirmation result chaining phase. The initialization phase comprises the steps that a certificate authority CA finishes signing various participating entity public key certificates of a network system, a data source provider P finishes selecting a signing key pair and an encryption key pair, blocking data and generating data block authentication information, and a third party ownership confirmation center T finishes authenticating block chain ownership registration commercial network B. The sampling challenge phase comprises the step that the third party ownership confirmation center T finishes sampling and authenticating data blocks. The ownership confirmation result chaining phase comprises the step that the block chain ownership registration commercial network B finishes registering an ownership confirmation result. The ownership confirmation method is the big data oriented ownership confirmation method based on the third party ownership confirmation center and a block chain, and the data ownership definition fairness and the completeness and credibility of the ownership result can be effectively ensured.
