Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.
It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the conditions under which the present invention can be implemented, so that the present invention has no technical significance, and any structural modification, ratio relationship change, or size adjustment should still fall within the scope of the present invention without affecting the efficacy and the achievable purpose of the present invention. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.
The block chain-based data supervision method, the block chain-based data supervision system, the block chain-based data supervision medium and the supervised terminal realize effective supervision of data of the supervised party through the cooperation of the supervising party and the supervised party based on the block chain and the encryption algorithm, avoid leakage of data privacy and have high practicability. The blockchain is a shared database, and the data or information stored in the blockchain has the characteristics of being unforgeable, having a trace in the whole process, being traceable, having a transparent public property, having a collective maintenance property and the like. Based on the characteristics, the block chain technology lays a solid 'trust' foundation, creates a reliable 'cooperation' mechanism, and is particularly suitable for the application scene of data supervision of the invention.
As shown in fig. 1 and fig. 2, in an embodiment, the block chain-based data policing method of the present invention is applied to a supervised terminal, and includes the following steps:
and step S1, forming a block chain alliance with the supervision terminal.
Specifically, in the invention, the supervising terminal and the supervised terminal form a block chain alliance to realize the storage of data based on the block chain technology.
Step S2, processing the supervision data of the supervised terminal into a hash value, and performing uplink.
Specifically, the supervision data such as the service data in the supervised terminal is subjected to Hash (Hash) processing, and uplink processing is performed on the obtained Hash value. Through uplink processing, data is under the joint monitoring of a monitoring party and a monitored party; the data is endowed with non-tamper property through the characteristics of the block chain, so that the authority of the data is ensured.
The hash process is to convert an input of an arbitrary length into an output of a fixed length by a hash algorithm, and the output is a hash value. This transformation is a kind of compression mapping, i.e. the space of hash values is usually much smaller than the space of inputs, different inputs may hash to the same output, so it is not possible to determine a unique input value from a hash value. Therefore, the hash value is just a meaningless string, and the supervisory data cannot be decrypted reversely, i.e., the supervisory data is still not exposed. But if the supervision data is tampered with, both the supervision terminal and the supervised terminal can know, so that the authenticity and the validity of the supervision data can be ensured.
And step S3, operating a supervision sandbox provided by the supervision terminal on the own network of the supervised terminal to generate a supervision result of the supervision data based on the supervision sandbox.
Specifically, the supervision terminal provides the supervision sandbox to the supervised terminal. And the supervised terminal runs the supervision sandbox on the own network to supervise and process the supervision data. In this process, the supervised terminal has no knowledge of the logical one of the supervision sandboxes. But the supervision sandbox can be effectively prevented from transmitting any data outwards due to the adoption of the own network of the supervised terminal. That is, the supervising terminal cannot acquire any data of the supervised terminal, and data privacy is protected. Therefore, in the invention, the supervising terminal grasps the rule, and the supervised terminal grasps the data, and both sides cannot independently decide or predict the execution result, thereby embodying the maximum fairness and fairness.
Preferably, during the execution of the supervision sandbox, whether the supervision data is tampered or not is verified based on the block chain node of the supervised terminal, so that the data of the supervised terminal is not possibly tampered.
And step S4, submitting the supervision result to the supervision terminal.
Specifically, the supervised terminal uploads the supervision result obtained by the supervision sandbox to the supervision terminal, so that the supervision terminal can obtain the supervision result.
Preferably, when submitting the supervision result to the supervision terminal, the supervision result is encrypted first, and then the encrypted supervision result is submitted to the supervision terminal. Therefore, although the supervision result is generated at the supervised terminal, the supervised terminal cannot change the supervision result without obtaining the supervision result. The supervision terminal can obtain the final supervision result only after decrypting the encrypted supervision result.
The block chain based data supervision method of the present invention is further described by the following specific embodiments.
In the prior art, national banks and national libraries of China have supervision and control responsibilities for centralized payment and received business of various commercial banks. In a traditional working mode, in order to consider the data privacy of a commercial bank, people banks send specialized personnel to the commercial bank site to extract data in a sampling mode for comparison, and then find out whether the business is in compliance. However, this method is inefficient and prone to errors, and the sampling method may result in some non-compliant services being spoofed and over-screened, and thus not being able to perform full screening.
By adopting the block chain-based data supervision method, the personnel and the commercial banks can form a alliance chain, then the commercial banks perform Hash chain connection on the supervision data, the personnel can deploy own supervision sandbox programs in the commercial banks, and the supervision results are submitted by the commercial banks. So rely on, whole supervision process becomes off-site by the scene, and the electronization is replaced by manual, can cover the total data moreover, and the accuracy promotes greatly, and the execution efficiency will also improve greatly.

The submitting module 34 is connected to the supervising module 33, and is configured to submit the supervising result to the supervising terminal.
The structures and principles of the composition module 31, the processing module 32, the supervision module 33, and the submission module 34 correspond to the steps in the block chain-based data supervision method one to one, and therefore are not described herein again.
In an embodiment of the present invention, the monitoring module 33 is further configured to verify whether the monitoring data is tampered with based on the block link point of the monitored terminal during the execution of the monitoring sandbox.
In an embodiment of the present invention, when the submitting module 34 submits the monitoring result to the monitoring terminal, the monitoring result is encrypted first, and then the encrypted monitoring result is submitted to the monitoring terminal.
