Embodiment approach 1

[0066] Embodiment 1: The data operation rule may adopt at least one of the following: addition, subtraction, multiplication, division, or a combination of addition, subtraction, multiplication, and division. Preferably, the more complex the data operation rules, the better.

Embodiment approach 2

[0067] Embodiment 2: A set of encryption and decryption algorithms can be used for the data operation rules, and the encryption and decryption algorithms can encrypt and decrypt the statistical data to be processed.

[0068] The block chain-based data statistics method described in any of the above also includes verifying each client to verify whether it participates in data statistics, and if it participates, it will perform statistics according to the aforementioned steps; if it does not participate, it will be considered that the client's Pending stats are zero. In this way, the number of participating data statistics clients can be adjusted at any time, the non-participating clients can be skipped, and the next client can continue without restarting, which greatly reduces the number of transactions.

[0069] This embodiment also provides a block chain-based data statistics device, including:

[0070] at least one processor; and,

[0071] a memory communicatively coupled ...

Abstract

The invention discloses a data statistics method and device based on a block chain, and a medium. The method comprises the following steps: acquiring random data generated by a management end, encrypting the random data by adopting a public key of a first user end to obtain a random data ciphertext, and sending the random data ciphertext to the first user end; acquiring a first statistical result,encrypting the first statistical result by adopting a public key of a second user side to obtain a first statistical result ciphertext, and sending the first statistical result ciphertext to the second user side; obtaining a second statistical result, encrypting the second statistical result by adopting the public key of the management end to obtain a second statistical result ciphertext, and sending the second statistical result ciphertext back to the management end; and obtaining a final statistical result, and uploading the final statistical result to the data statistical block chain. According to the method disclosed by the invention, the data of each party can be counted while the data of each party on the blockchain is kept secret, so that the data of each party achieves an effect of being available and invisible.

Description

technical field [0001] This application relates to the technical field of blockchain applications, in particular to a blockchain-based data statistics method, equipment, and media. Background technique [0002] In the digital economy era, data is the core asset of an enterprise, and data encryption protection is one of the effective means to protect enterprise assets. However, in the data life cycle link, the confidentiality of the data statistical processing process has not been well resolved due to technical and other reasons. [0003] In the past, in order to keep the statistical processing process of data confidential, enterprises often controlled the data and the statistical calculation process of the data under their own control, that is, the data and the statistical calculation process of the data were all in the unified security domain within the enterprise. , so as to protect the confidential data of the enterprise and ensure that there will be no problems such as ...
