Problems solved by technology

[0003] The data in the existing blockchain is usually uploaded to the blockchain by merchants or manufacturers. As a vulnerable party, users cannot fully participate in the entire life cycle of data in the chain. For users, there are still blind spots in data management

Embodiment 1

[0041] Embodiment 1 of the present application provides a data management method based on blockchain technology, such as figure 1 As shown, it is applied in security hardware, and the method specifically includes the following steps:

[0042] Step 110. Before leaving the factory, the secret security hardware stores the public-private key pair generated according to the product serial number. The private key is stored in the secret security hardware and cannot be exported, and the public key is used as the generated address; or the secret security hardware only stores the key pair generated according to the product serial number private key, the private key is stored in the security hardware and cannot be exported;

[0043]Before leaving the factory, the software system or encryption device produced in a safe environment generates a public-private key pair according to the unique product serial number burned by the encryption hardware, and the public-private key pair is importe...

Embodiment 2

[0059] Embodiment 2 of this application provides a data management method based on blockchain technology, which is applied in smart contracts, such as image 3 As shown, each smart contract is deployed on a blockchain node of the blockchain network. According to the characteristics of the blockchain, each blockchain node is related to each other, so that when a customer connects to one of the blockchain nodes through the UI software interface, Smart contracts on all blockchain nodes can be accessed when the smart contract on the blockchain node is opened.

[0060] Such as Figure 4 As shown, the data management method based on block chain technology specifically includes the following steps:

[0061] Step 410, in response to receiving the address sent by the manufacturer's system background, the smart contract saves the address, generates security data, and sets enabling conditions for the security data;

[0062] After the customer purchases the security hardware, the securi...

Embodiment 3

[0079] Embodiment 3 of the present application provides a data management system based on blockchain technology, including security hardware, customer terminals, smart contracts, and smart contracts in other blockchain nodes in the blockchain network;

[0080] The secret protection hardware executes the data management method based on blockchain technology as shown in Embodiment 1;

[0081] The smart contract executes the data management method based on blockchain technology as shown in Embodiment 2, and sends corresponding data processing instructions to other smart contracts through the blockchain network after performing data operations;

[0082] The customer terminal is connected to the security hardware and the smart contract, as the transmission medium for the data transmission between the security hardware and the smart contract, and provides a UI software interface, and realizes the data of the security hardware and the smart contract in the blockchain node by operating...

Abstract

The invention discloses a data management method, device and system based on a block chain technology. The system comprises password protection hardware, a customer terminal, an intelligent contract and intelligent contracts in other blockchain nodes in a blockchain network. The encryption hardware comprises a key storage module, an export module and a signature module; the intelligent contract comprises an address import module, a verification module and an operation notification module; and the customer terminal is connected with the password protection hardware and the intelligent contractto achieve data interaction between the password protection hardware and the intelligent contract in the blockchain node. According to the method, a private key in cryptographic hardware is used as averification key for data management, so that the data security is ensured; and an address generated by a factory public key is used for ensuring that customers participate in the full life cycle of data management, so that the publicity and transparency of the data are further realized.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a data management method, device and system based on blockchain technology. Background technique [0002] Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "retaining traces throughout the process", "traceable", "open and transparent", and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects. [0003] The data in the existing blockchain is usually uploaded to the blockchain by merchants or manufacturers. As a disadvantaged party, users cannot fully participate in the entire life cycle of the data in the chain. For users, there are still blind spots in data management. Contents of the inven...
