Data Security System And Data Security Method Based On Block Chain

摘要

The present invention relates to a blockchain-based data security system and a blockchain-based data security method. The blockchain-based data security system of the present invention stores the generated data, encrypts the data, and stores a local storage capable of decrypting the encrypted data. A data distribution determining unit which determines data to be distributedly processed according to a first setting condition among the data stored in the local storage, and A data operation module including a data division unit for dividing the data determined by the data dispersion determination unit into at least a first dispersion division data and a second dispersion division data; And A first distributed storage connected to the data operation module and the Internet communication network to store the first distributed data and allowing a portion of the first distributed data to be shared, the second distributed storage connected to the data operation module and the Internet communication network. And a second distributed storage for storing the divided data and allowing some of the data connected to the first distributed divided data to be shared with the second distributed divided data. In addition, the blockchain-based data security method of the present invention generates data, encrypts the data, and stores the data in a local storage, wherein the data stored in the local storage is distributed according to a first setting condition. (C) dividing the data determined in step (B) and (B) into at least first and second distributed data according to a second set condition; (D) storing the first distributed divided data in the first distributed storage and the second distributed divided data in the second distributed storage; and the first distributed divided data stored in the first distributed storage and the second distributed storage. (E) sharing some data of the second distributed partitioned data.
