Description
Technical Field
The embodiment of the invention relates to the field of block chains, in particular to a data isolation type sharing method, device, terminal and system based on block chains.
Background
The blockchain is a cryptographically concatenated transaction record (also called a block) that is cryptographically concatenated and protected in content. Each tile contains the cryptographic hash of the previous tile, the corresponding time stamp, and transaction data (typically represented by a hash value computed using the merkel tree algorithm), such a design makes the tile contents tamper-resistant. The distributed account book connected in series by the block chain can effectively record the transaction by two parties and permanently check the transaction. In which the concepts of data isolation and data sharing are involved.
The data isolation is to use the blockchain system to isolate two data interaction parties, so that a user cannot directly contact and use source data information provided by a data producer, and can only indirectly access processed data provided by the data producer through the blockchain system. Direct contact between two parties in the data sharing process is isolated, privacy and ownership of data are protected, and use value is provided for users. The core purpose of the invention is to realize data sharing under the condition of data isolation under the condition of protecting data privacy and ownership.
Data sharing refers specifically to the sharing of the use value of data owned by the data producer. On the premise of realizing data isolation based on a block chain system, a data producer indirectly shares data by issuing a data report generated based on source data processing, so that a user obtains the use value of the data.
The scheme for improving the efficiency in the data sharing process exists in the current block chain technology, which mainly embodies the solution of data sharing and intercommunication among closed individuals, and realizes the sharing of data which can not be tampered among non-mutually trusted nodes based on the block chain technology. For example, the invention with application date of 2018, 5/2 and publication number of CN108599969A, entitled "method and apparatus for sharing data in blockchain", and the invention with application date of 2018, 5/16 and publication number of CN108632292A, entitled "method and system for sharing data based on federation chain" are all solutions for implementing data sharing. However, on this basis, there are many problems with the direct sharing of source data between nodes:
first, direct sharing of source data is not conducive to protecting data privacy. Particularly in a distributed network system, the risk of data leakage is increased by directly sharing data, and the willingness of data producers to share data is reduced.
Second, direct sharing of source data is not conducive to maintaining the rights of the data producer. Direct sharing of source data can make transactions between data producers and users non-sustainable, and users can recycle or resell source data to other users after obtaining the source data through a single transaction. This data sharing mode is not conducive to the producer obtaining continuous benefit from data sharing, and also reduces the data producer's willingness to share data.
Furthermore, source data based sharing schemes limit the scalability of the system. Particularly, if data is directly shared in the blockchain system, not only a large amount of storage space is occupied, but also more bandwidth is occupied in the process of uploading and downloading the data, which is not beneficial to the expansion and maintenance of the system and limits the application of the system in the real society.
The above description of the discovery process of the problems is only for the purpose of assisting understanding of the technical solutions of the present invention, and does not represent an admission that the above is prior art.

sending the first order to a second terminal through a second node, receiving a data sample sent to the second node by the second terminal, broadcasting the data sample to all nodes except the second node, wherein the second node is a node corresponding to the second terminal in a block chain, and the data sample comprises source data collected by the second terminal in advance;
processing the first order and the data sample by all nodes except the second node to generate a second order, and broadcasting the second order to the second node;
after the second order is sent to the second terminal through the second node, receiving an encrypted data report sent to the second node by the second terminal, and broadcasting the encrypted data report to all nodes except the second node;
sending the encrypted data report to the first terminal through the first node.
2. The method of claim 1, wherein prior to said broadcasting said data sample to all nodes except said second node, said method further comprises:
verifying the data sample corresponding to the first order sent by the second terminal;
broadcasting the checked data sample to all nodes except the second node.
3. The method of claim 1, further comprising:
and generating an order identification serial number which is uniquely corresponding to the second order according to the second order.
4. The method of claim 1, wherein prior to said broadcasting said encrypted data report to all nodes except said second node, said method further comprises:
electing a billing node for the encrypted data report by the second node;
storing the encrypted data report into a block according to the accounting node;
all nodes in a block chain synchronize encrypted data reports in the block.
5. A data isolation type sharing method based on a block chain is characterized by comprising the following steps:
receiving user demand information by a terminal;
the terminal generates a first order according to the user demand information and sends the first order to a first node, wherein the first node is a node of the block chain corresponding to the terminal;
and the terminal receives the encrypted data report sent by the first node, decrypts the encrypted data report and acquires encrypted content.
6. A data isolation type sharing method based on a block chain is characterized by comprising the following steps:
receiving a first order sent by a second node;
generating a data sample corresponding to the first order according to the first order and pre-collected source data, and sending the data sample to the second node;
receiving a second order sent by the second node;
and arranging the collected source data according to the second order to generate a data report, encrypting the data report and sending the encrypted data report to the second node.
7. The device is characterized by comprising a blockchain and a processor, wherein the blockchain comprises a plurality of nodes, a first node is a node of the blockchain corresponding to the first terminal, and a second node is a node of the blockchain corresponding to the second terminal;
the first node is used for receiving a first order sent by a first terminal and sending an encrypted data report to the first terminal;
the second node is used for sending a first order and a second order to the second terminal;
the processor configured with processor-executable operational instructions to perform the method steps of any of claims 1 to 4.
8. A terminal, characterized in that the terminal comprises a processor configured with processor-executable operational instructions to perform the method steps of claim 5.
9. A terminal, characterized in that the terminal comprises a processor configured with processor-executable operational instructions to perform the method steps of claim 6.
10. A blockchain based data-isolated sharing system, characterized in that the system comprises the apparatus of claim 7, the terminal of claim 8 and the terminal of claim 9.
