Problems solved by technology

[0009] (1) The existing methods of participating in data privacy protection in the form of software and hardware integration mostly stay at the stage of data storage and hash chaining, and truly combined with blockchain technology to conduct credible privacy and security calculations is still exist challenges
[0010] (2) The existing method of using cryptography to solve the privacy protection problem in the process of data use, the data input into the smart contract from the external connection has not been processed and verified, and the source lacks credibility; the ownership registration process of the data subject is complicated and cumbersome, and The traditional solution lacks a chain of evidence, making it difficult to trace the source
[0011] (3) The existing method of using cryptography to solve the problem of privacy protection in the process of data use, users are using private data without knowing it, and it is difficult for the data subject to control their own data; in the process of multi-party joint computing, the data is easy to Leakage, and there are problems of fraud and unreliability in the joint calculation process
[0012] (4) Most of the current blockchain projects carry out data results on the chain, which cannot guarantee the safety and reliability of the calculation process, resulting in a decrease in the trust of the consensus process
[0013] (5) Blockchain nodes bring inconvenience to the deployment of nodes, increase the threshold for joining the blockchain, and cannot improve services and benefits for those who do not understand the network or blockchain, hindering the actual promotion of the blockchain
[0014] (6) The existing method of initiating transactions by calling the smart contract interface deployed on the blockchain through the user's own input data cannot guarantee the credibility of the data source
Although there are currently oracle contracts that can help smart contracts collect external data outside the chain, it still cannot guarantee whether the external information source is credible
[0015] (7) Existing solutions are generally centralized management, leading to privacy leakage, data control and other issues
Data is easily leaked during the multi-party joint calculation process, and there are problems of fraud and unreliability in the joint calculation process
In addition, most of the current blockchain projects carry out data results on the chain, which cannot guarantee the safety and reliability of the calculation process, resulting in a decrease in the trust of the consensus process

Embodiment 1

[0109] Aiming at the problems existing in the existing technology, the present invention provides a solution, hardware equipment, devices, and edge terminals based on block chain chips, software and hardware integration for data right confirmation, encrypted storage, and private data security multi-party computing. Improve privacy protection during data transfer and use.

[0110] Blockchain anonymous computing hardware (platform) is an integrated product of blockchain software and hardware developed for data authentication, secure storage, joint computing and trusted execution under the background of data sharing and use. The present invention proposes a blockchain-based trust computing model, and relies on cryptography (such as secure multi-party, zero-knowledge proof, etc.) technologies to realize the manageability, usability and verifiability of data under privacy protection. At the same time, the present invention provides users with a trusted distributed plaintext computi...

Embodiment 2

[0165] Blockchain anonymous computing hardware can realize the integration of software and hardware, and realize trusted collection of data sources, encrypted storage, verification of rights, and joint use. The blockchain anonymous computing hardware has a built-in node public and private key and a node startup program, and can build a private blockchain chain or connect to a blockchain (Ethereum) network with one click.

[0166] In one embodiment, such as Figure 5 Shown is the general process of data collection and processing by the blockchain anonymous computing hardware. The blockchain anonymous computing hardware is embedded with IoT chips, which can collect automation data, status data, and file data through technologies such as wireless networks (WIFI, 4G / 5G), sensors, wired connections, and radio frequency identification. In addition, the node is embedded with a GPS chip, which can realize the location tracking of the data source. The block chain anonymous computing ...

Embodiment 3

[0182] Blockchain anonymous computing hardware can perform secure privacy computing between data owners and data demanders. In one embodiment, such as Image 6 Shown is the joint calculation process between the data owner and the data demander. Through blockchain anonymous computing hardware, data owners and data demanders can conduct secure joint computing under the condition of protecting the privacy of data subjects.

[0183] Before describing the specific process of calculation, the initialization description is given first. As described in the first aspect of the summary of the invention, the following process will be sent to the blockchain network in the form of a transaction, which will be consensused by other nodes. The data address generated by the box for this data calculation is 0xdata_x, the count of this calculation is initialized to 0, the dataRoot is empty, the balance is empty, and the proofChain is initialized as the head node of this calculation process, wh...
