Fig. 1 is a schematic view of a scenario of a data processing method based on blockchain storage according to an embodiment of the present disclosure, where as shown in fig. 1, the scenario includes a first secure computing node deployed at an authority, a second secure computing node deployed at an energy data center, a data authorization system of an energy user, and a blockchain system. The first secure computing node may comprise a background server or a cluster of servers located at an authority.

The blockchain node may also send an authorization query credential to a second secure compute node deployed in the energy data center, where the authorization query credential is used for the second secure compute node to query authorization information in the blockchain system.

In fig. 1, the first secure computing node may send an energy usage data query request for the energy usage party to the second secure computing node based on the certified authorization information and the received authorization success information, so as to query the energy usage data of the energy usage party in the energy data center. After receiving the energy use data query request, the second security computing node queries the authorization information in the block chain system according to the authorization query certificate so as to judge whether the first security computing node has the authority to acquire the energy use data. And after determining that the first safe computing node has the authority to acquire the energy use data, sending the energy use data to the first safe computing node. In fig. 1, after receiving the energy usage data of the energy consumer, the first secure computing node performs risk control on the resource pre-paid amount of the energy consumer in combination with the auxiliary wind control data for performing risk control on the resource pre-paid amount of the energy consumer.

In the scenario shown in fig. 1, the authorization authority may acquire the energy usage data of the energy user in a block chain verification and authorization manner, and perform risk control on the resource pre-payment amount of the energy user in combination with the energy usage data, so that the authority may acquire enough data of the energy user as much as possible, and accuracy of performing wind control on the energy user by the authority is improved.

A data processing method based on block chain storage is described below from the perspective of the first secure computing node.

Fig. 2 is a schematic flowchart of a data processing method based on block chaining verification according to an embodiment of the present disclosure, where the flowchart is applied to a first secure computing node and executed by the first secure computing node, and as shown in fig. 2, the flowchart includes:

and S206, acquiring auxiliary wind control data for performing risk control on the resource prepayment amount of the energy user, and performing risk control on the resource prepayment amount of the energy user according to the auxiliary wind control data and the energy use data.

In the data processing method based on block chain storage certificate in the embodiment of the description, the authority can be authorized to acquire the energy usage data of the energy user from the energy data center in a block chain storage certificate and authorization mode, so that the authority performs risk control on the resource pre-payment amount of the energy user by combining the energy usage data, the authority can acquire enough data of the energy user as far as possible, and the accuracy of the authority performing wind control on the energy user is improved.

In step S202, the first secure computing node sends an energy usage data query request for the energy usage party to the second secure computing node based on the authorization information of the energy usage data of the energy usage party stored in the blockchain system. The method comprises the following steps:

(a1) Acquiring authorization success information which is issued to an authority after the block chain system stores the authorization information of the energy use data of the energy user; the authorization success information indicates that the energy source using party authorizes the energy source using data of the energy source using party to an authority;

(a2) And sending an energy use data query request aiming at the energy user to a second safety computing node deployed in the energy data center according to the authorization success information.

Specifically, after a user of the energy source user authorizes the energy source usage data of the energy source user to the authority through the data authorization system, authorization information is stored in the block chain system, and after the block chain system stores the authorization information, authorization success information is issued to the authority, for example, authorization success information is issued to a first safety calculation node of the authority. The content of the authorization success information indicates that the energy usage party authorizes the energy usage data of the energy usage party to the authority.

The authorization success information may carry identification information of the energy user, so that the first secure computing node can obtain the authorization success information conveniently. The first safety computing node obtains the successful authorization information, analyzes the content of the successful authorization information, and sends an energy use data query request aiming at the energy user to the second safety computing after determining that the content of the successful authorization information indicates that the energy user authorizes the energy use data of the energy user to an authority, so that the energy use data query request is sent after the authorization of the energy user is ensured, the success rate of data query is improved, and the legal use of the energy use data is ensured.

In this embodiment, the first secure computing node and the second secure computing node are both in a multi-Party secure computing (MPC) platform, and both the first secure computing node and the second secure computing node are nodes in the multi-Party secure computing platform. Based on the multi-party secure computing technology, data transmitted between the first secure computing node and the second secure computing node are in a ciphertext form, so that the security of the data processing process is ensured. Based on this, in step S202, the first secure computing node sends an energy usage data query request for the energy consumer to the second secure computing node, which is specifically: the first secure compute node sends an energy usage data query request for an energy consumer in the form of a ciphertext to the second secure compute node. Correspondingly, in step S204, the obtaining, by the first secure computing node, the energy usage data of the energy user returned by the second secure computing node according to the energy usage data query request specifically includes: and the first safety computing node acquires the energy use data of the energy user in the form of the ciphertext returned by the second safety computing node according to the energy use data query request.

In the data transmission process, the second secure computing node may decrypt the energy usage data query request in the form of the ciphertext based on a decryption algorithm predetermined by the multi-party secure computing platform, and the first secure computing node may decrypt the energy usage data in the form of the ciphertext based on a decryption algorithm predetermined by the multi-party secure computing platform.

Because the first safe computing node and the second safe computing node are both nodes in the multi-party safe computing platform, data transmitted between the first safe computing node and the second safe computing node are both in a ciphertext form, including but not limited to an energy use data query request in the ciphertext form and energy use data in the ciphertext form, so that the safety of data communication between the first safe computing node and the second safe computing node is ensured, and the data transmitted between the first safe computing node and the second safe computing node cannot be illegally cracked by a third party.

After the first secure computing node of the authority mechanism obtains the energy usage data of the energy user, step S208 is executed to obtain auxiliary wind control data for performing risk control on the resource pre-payment amount of the energy user, and according to the auxiliary wind control data and the energy usage data, the resource pre-payment amount of the energy user is subjected to risk control.

In this embodiment, the authority may be a financial institution such as a bank, the energy may be electric energy, the energy using party may be a power consumption enterprise, the energy data center may be a power grid center, the resource may be a loan or virtual digital currency, and the resource budget amount may be a loan amount or a virtual digital currency amount.

Accordingly, the energy usage data of the energy user includes, but is not limited to, electricity usage data of the energy user, and the electricity usage data of the energy user includes at least one of electricity consumption data, electricity fee payment data, arrearage data, and electricity stealing data.

Wherein the power consumption data comprises at least one of: daily power consumption data, monthly power consumption data, annual power consumption data, daily average power consumption data, monthly average power consumption data, annual average power consumption data, monthly power consumption ranking in the industry, annual power consumption ranking in the industry, monthly average power consumption data in the industry, and annual average power consumption data in the industry.

In this embodiment, the auxiliary wind control data includes, but is not limited to, at least one of tax payment data, sales data, and business invoice data of the energy consumer. The auxiliary wind control data may also include business traffic data of the energy consumer with other enterprises or units.

In step S208, performing risk control on the resource budget limit of the energy user according to the auxiliary wind control data and the energy usage data, including:

(b1) Determining a first confidence coefficient that the energy user belongs to a specified industry according to the energy use data, and determining a first capacity scale of the energy user;

(b2) According to the auxiliary wind control data, determining a second confidence coefficient that the energy user belongs to the designated industry, and determining a second capacity scale of the energy user;

(b3) And performing risk control on the resource pre-payment amount of the energy user according to the first confidence coefficient, the first capacity scale, the second confidence coefficient and the second capacity scale.

Wherein the designated industry may include manufacturing.

In the act (b 1), a first confidence that the energy consumer belongs to the manufacturing industry may be determined based on the electricity consumption data of the energy consumer. For example, a threshold corresponding to the monthly average power consumption of the energy user is preset, if the monthly average power consumption of the energy user in the last half year is smaller than the threshold, a first confidence that the energy user belongs to the manufacturing industry is determined to be 0, if the monthly average power consumption of the energy user is greater than or equal to the threshold, a difference between the monthly average power consumption and the threshold is calculated, a value of a first confidence that the energy user belongs to the manufacturing industry is determined according to the difference and a value of a first confidence corresponding to a preset difference, and the larger the difference is, the larger the first confidence is, the more likely the energy user belongs to the manufacturing industry is indicated.

In the act (b 1), the first capacity size of the energy consumer may be determined based on the power consumption data of the energy consumer. For example, the correspondence between different monthly average power consumptions of the energy consumers and different first capacity scales is preset, and the first capacity scale can be represented by a large scale, a medium scale and a small scale, so that the first capacity scale of the energy consumers is determined according to the monthly average power consumptions of the energy consumers and the preset correspondence, and the larger the monthly average power consumption is, the larger the first capacity scale is, and the larger the first capacity scale is, the more likely the energy consumers belong to the manufacturing industry.

In act (b 2), a second confidence level that the energy consumer belongs to the manufacturing industry may be determined based on the auxiliary wind control data of the energy consumer. For example, a first quantity of finished equipment which can be purchased by a user and a second quantity of raw materials which can be purchased are obtained according to material purchasing data of the energy user, a second confidence coefficient of the energy user is determined according to a ratio between the first quantity and the second quantity and a corresponding relation between a preset ratio and the second confidence coefficient, wherein the smaller the ratio, the larger the second confidence coefficient is, the more likely the energy user belongs to the manufacturing industry.

In the act (b 2), the second capacity scale of the energy consumer may be determined according to the auxiliary wind control data of the energy consumer. For example, the second capacity scale of the energy user is determined according to the quantity of the equipment generated by the energy user per year reported to the relevant department, the second capacity scale can be represented by a large scale, a medium scale and a small scale, and the larger the second capacity scale is, the more likely the energy user belongs to the manufacturing industry.

In the action (b 3), the risk control is performed on the resource pre-payment amount of the energy user according to the first confidence level, the first capacity scale, the second confidence level and the second capacity scale. In one embodiment, the risk control of the resource budget limit of the energy consumer according to the first confidence level, the first capacity scale, the second confidence level and the second capacity scale includes: and determining the risk level of the resource pre-payment amount of the energy user according to the first confidence coefficient, the first capacity scale, the second confidence coefficient and the second capacity scale.

Specifically, a risk level calculation formula may be preset, and the risk level of the resource prepayment amount of the energy consumer may be determined by the formula. For example, the risk level = 1/((first confidence + second confidence) × first coefficient + (first capacity scale + second capacity scale) × second coefficient), i.e., the risk level is equal to (first confidence + second confidence) × first coefficient + (first capacity scale + second capacity scale) × reciprocal of the second coefficient. In the formula, the first coefficient and the second coefficient are preset coefficients. In the formula, the risk level is inversely proportional to the first confidence level, the second confidence level, the first capacity scale and the second capacity scale, and the risk level of the energy user is smaller as the energy user is predicted to belong to the manufacturing industry more likely through the first confidence level, the second confidence level, the first capacity scale and the second capacity scale.

In another embodiment, the risk control of the resource budget amount of the energy consumer according to the first confidence level, the first capacity scale, the second confidence level and the second capacity scale includes: and according to the first confidence coefficient, the first capacity scale, the second confidence coefficient and the second capacity scale, determining the risk level of the resource pre-payment amount of the energy user, and according to the risk level of the resource pre-payment amount of the energy user, evaluating the resource pre-payment amount of the energy user to obtain the resource pre-payment amount corresponding to the energy user.

Specifically, first, the risk level of the resource prepayment amount of the energy consumer is calculated by the risk level calculation formula.

And then, generating an authorization query credential corresponding to the authorization information according to the hash value, wherein the authorization query credential comprises the hash value. For example, the hash value is used as an authorization query credential. When the authorization information is stored in the blockchain system, the storage format can be 'hash value of the authorization information-authorization information', so that when the blockchain system receives the authorization query certificate, the blockchain system can query according to the hash value of the authorization information to obtain the authorization information. After the block link node generates the authorization query credential, the authorization query credential is sent to the energy data center, for example, to the second secure computing node.

The foregoing description of specific embodiments has been presented for purposes of illustration and description. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims can be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain a corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD) (e.g., a Field Programmable Gate Array (FPGA)) is an integrated circuit whose Logic functions are determined by a user programming the Device. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually manufacturing an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development, but the original code before compiling is also written in a specific Programming Language, which is called Hardware Description Language (HDL), and the HDL is not only one kind but many kinds, such as abll (Advanced boot Expression Language), AHDL (alternate hard Description Language), traffic, CUPL (computer universal Programming Language), HDCal (Java hard Description Language), lava, lola, HDL, PALASM, software, rhydl (Hardware Description Language), and vhul-Language (vhyg-Language), which is currently used in the field. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be regarded as a hardware component and the means for performing the various functions included therein may also be regarded as structures within the hardware component. Or even means for performing the functions may be conceived to be both a software module implementing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
