Embodiment 1

[0088] Combine below Figure 1A The shown system introduces a data sharing method provided by the embodiment of the present application. The present application takes the first node to share data with N nodes as an example, wherein the second node is one node among the n nodes. In the introduction When n nodes obtain the shared data (ie, the target data in the embodiment of the present application), the second node is taken as an example for illustration. It should be understood that the above-mentioned first node, n nodes and second nodes are all nodes in the blockchain network, such as Figure 3A As shown, this data sharing method can be implemented by Figure 1A As shown in the system implementation, specifically, the method includes some or all of the following steps:

[0089] S11: The first node receives a sharing request for the target data, and the sharing request is used to request to share the target data with n nodes in the blockchain network, where n is a positive i...

Embodiment 2

[0118] Combine below Figure 1B The system shown introduces another data sharing method provided by the embodiment of this application. In this method, ordinary nodes do not have the authority to upload data to the blockchain network, and their proxy nodes complete the upload. This application takes the first node to share data with n nodes as an example to illustrate, wherein, the second node is one of the n nodes, and n nodes are introduced to obtain the shared data (that is, in the embodiment of this application, the target data) is described by taking the second node as an example. It should be understood that the first node, the n nodes, the first proxy point, the second node, and the second proxy node are all nodes in the blockchain network, such as Figure 3B As shown, this data sharing method can be implemented by Figure 1B As shown in the system implementation, specifically, the method includes some or all of the following steps:

[0119] S21: The first node sends...

Abstract

The embodiment of the invention discloses a data sharing method and a related device, equipment and system. The data sharing method comprises the following steps of: sharing data, the first node or the proxy node of the first node receives a sharing request for indicating to share the target data to n nodes in the blockchain network, generates a first multiple signature address according to the public keys of at least n nodes, and encrypts the target data through the first multiple signature address to obtain first transaction data; and then, uploading the first transaction data to a blockchain network, and after receiving the first transaction data, the n nodes decrypt the first transaction data according to at least i private keys included in the private keys of the at least n nodes to obtain target data. According to the method, a fair and supervisable data sharing mode is provided, the data sharing process is transparent and fair, and the safety of the shared data can be improved and protected.

Description

technical field [0001] The present invention relates to the field of Internet technology, in particular to the field of data processing technology, and in particular to a data sharing method and related devices, equipment and systems. Background technique [0002] Between various government departments or between various departments of the company, and between various employees in each department, the data is isolated from each other. If an employee wants to share data with multiple employees in other departments, the member who needs to initiate the data sharing needs to send the shared data to the designated multiple employees one by one, or upload the shared data to the shared network disk on the Internet. Send the access link of the data in the network disk to the designated multiple employees. These implementation methods are unsupervised, and the access link can be copied, causing other people outside the designated multiple employees to also obtain the data, and the ...
