Abstract
Data centric storage with network as the carrier is vulnerable to external attacks, resulting in data loss and tampering. We propose a method of tamper proofing for block chaining data without centralization and centralization. According to the technology principle of bitcoin block chain, the network data information is protected by block chain encryption technology, and the security of high information tamper resistant is realized. A block chain data storage algorithm based on hash table is hereby proposed, which can get enough address sp ace to save all the data, and make block chain form a time sequence to achieve the safe transmission of data. The research results show that the data protection method has very high tamper resistance ability because of the high security of encrypted digita l block chaining technology. The block chain implements the value transfer without relying on centralized organization.
