Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without any creative effort shall fall within the protection scope of the present specification.
In order to better understand the inventive concept of the present application, a service supervision system according to an embodiment of the present specification is first introduced. As shown in fig. 1, the traffic policing system includes a plurality of service nodes. Each service node is provided with a front-end device 1, a database server 2 and an application server 3.
The service nodes can exchange data with each other, and data transmission between the service nodes is realized. Specifically, a block chain 4 may be formed between the service nodes, all the service nodes have peer-to-peer rights, and each item of data is sent to each node in the system. In specific implementation, the data may be sent to a certain number of adjacent nodes, so that other nodes receive the data and then forward the data to the adjacent nodes according to a certain rule, and finally, each node can receive the transaction information.
The head-end 1 may be a device capable of interacting with a user. For example, the front-end device 1 may display a corresponding operation interface through the PC display and the mobile display screen 5, and acquire data input by the user based on the operation interface. The front-end device 1 may perform data transmission with the database server 2, so as to send data to the database server 2 for data storage, or perform data forwarding based on the database server 2.
The database server 2 is mainly used for storing various data, including data sent by the front-end device 1 and the application server 3, or data acquired through data communication between the front-end device and the application server in the service supervision system.
The application server 3 is mainly responsible for processing data, for example, for the de-signing of the digital signature to verify the security of the data, and also can verify the service data through the supervision data. The application server 3 communicates with the database server 2 primarily to store data to the database server 2.
Based on the above service supervision system, a service supervision method based on a block chain in the embodiment of the present specification is introduced. The execution subject of the block chain-based service supervision method is the service supervision system. As shown in fig. 2, the block chain based traffic policing method may include the following specific implementation steps.
S210: the front-end equipment receives service data input by a user.
The service data may be related data that the user is involved in processing the service, and is used to introduce information about the user, service, and the like.
In some embodiments, in the case that the current scenario is for auditing loan authority of a person or institution, the business data may also be at least one of user identity information, user property information, user collateral information, application loan information. The user identity information can be information which can determine the user identity, such as the identity card number of the user, the user name, the birth year and month, the institution code and the like; the user asset information can be information of assets affiliated to the user, such as asset types, asset amounts, asset specific affiliations and the like; the user collateral article information can be information of articles which can be used for collateral by the user in the business, such as the value and the type of the collateral articles; the loan application information may be records of past applications of the loan by the user, including the type of the loan application, the amount of the loan application, and the like. The above examples are only described as a few specific examples of the service data, and in practical applications, other contents may be selected as the service data according to needs, which is not limited to this.
In some embodiments, the front-end device corresponds to a display screen, and may be configured to display a corresponding input interface of a user, so that the user inputs corresponding service data based on the input interface. In practical application, other manners may also be adopted to obtain the service data, which is not described herein again.
S220: the front-end equipment encrypts the service data by using a private key to obtain a digital signature.
After the front-end device obtains the service data, the service data can be encrypted by using a private key to obtain a digital signature. After the digital signature is sent to the receiver, the receiver can use the corresponding public key to sign off the digital signature so as to verify the service data and ensure the accuracy of the received data.
The specific manner of obtaining the digital signature by encryption may be set according to the requirements of the actual application, and is not described herein again.
In some embodiments, the front-end device may obtain the service digest data from the service data after receiving the service data, and then encrypt the service digest data by using a private key to obtain a digital signature. Since the whole service data may have a large data volume, directly encrypting the service data may consume a large amount of time and resources, and thus, the time and resources consumed in the encryption process may be reduced by extracting the service digest data.
In the above embodiment, preferably, the service digest data may be obtained by performing a hash operation on the service data. Of course, other access rules may also be used to obtain the service summary data according to the service data, which is not described herein again.
S230: and the front-end equipment sends the service data and the digital signature to the database server.
After the front-end device obtains the service data and the data signature, the front-end device may send the service data and the digital signature to a database server to perform subsequent steps.
S240: and the database server sends the service data and the digital signature to the application server.
After obtaining the service data and the data signature, the database server may send the service data and the digital signature to the application server to perform subsequent steps.
In some embodiments, while forwarding the service data and the digital signature, the database server may first store the service data and the digital signature in its own storage medium, so as to achieve a backup effect on the service data and the digital signature.
S250: and the application server verifies the service data based on the digital signature.
After receiving the digital signature, the application server may decrypt the digital signature by using the public key, and compare the decrypted result with the service data to determine whether the service data is modified or lost.
The public key may be a public key, such that the application server can directly utilize the public key to effect decryption. Under the condition that the public key corresponds to the private key of the front-end equipment, the public key can verify the digital signature, the possibility that other users forge the digital signature is also avoided, and the safety of user data is guaranteed.
Based on the implementation manner in step S220, if the application server extracts the service summary data for the service data when constructing the digital signature, the application server may also process the service data in a simultaneous manner when performing the verification, so as to obtain the service summary data, and then compare the digital signature after being de-signed with the service summary data, so as to implement the verification of the service data.
S260: and in the case of passing the verification, the application server stores the service data into the block chain.
If the comparison result between the data after being signed off and the service data is determined to be in accordance with the verification condition according to the comparison, the service data is normal, and the service data can be stored in the block chain. Because the block chain is maintained by all the service nodes together, the data on the block chain can be transmitted to other service nodes by one service node, so that all the service nodes can quickly and effectively acquire corresponding service data, and the service data is favorably utilized to carry out service auditing and processing.
The specific data storage process may refer to corresponding descriptions in the service supervision system, and will not be described herein again.
S270: the database server sends the supervision data to the application server.
The database server may send the corresponding administration data to the application server. The supervision data may be corresponding data corresponding to the user for evaluating the user and the service to be performed. In some embodiments, the regulatory data may include at least one of transaction information, deposit correspondence limit information.
Transaction information may be used to refer to past transaction data for the user, such as information about transaction time, transaction type, transaction outcome, etc. The deposit information may be used to refer to a deposit provided by the user for the transaction to ensure the validity and controllability of the transaction. The limit information corresponding to the deposit can be used for referring to the loan amount corresponding to the deposit used in the service, so that the service supervision can be realized more conveniently.
In practical applications, other types of supervision data can be used for convenience of supervision, and are not limited to the above examples, and are not described herein again.
S280: the application server calculates a supervision result corresponding to the traffic data based on the supervision data.
After the application server acquires the supervision data, the application server can calculate a corresponding supervision result by using the supervision data. And the supervision result is used for representing an auditing result aiming at the business.
In some embodiments, a traffic size limit may be calculated based on supervision data, and the traffic size limit may be compared with the traffic data, and if the traffic data does not exceed the traffic size limit, the supervision result of the traffic data may be determined to be a normal supervision result. And if the service data exceeds the service scale limit, determining that the supervision result of the service data is an abnormal supervision result, and otherwise, determining that the obtained supervision result is a normal supervision result.
Specifically, the total loan amount of the financial institution and the total repayment amount of the financial institution are calculated according to the loan information of the financing guarantee institution and the repayment information of the financial institution in the original transaction information, the loan balance of the financing guarantee institution in the financial institution is obtained through calculation, the loan scale is obtained by corresponding the loan balance and the payment guarantee fund to the loan limit parameter mu, the loan scale is processed according to the comparison result, and the result is registered in the information storage module.
To illustrate by using a specific example, as shown in fig. 3, the application server includes an intelligent contract execution module, which includes an information processing module 331, an intelligent contract module 332, and an intelligent contract operation module 333.
First, the information processing module 331 reads the CashDept deposit paid by the financing security institution at the financial institution from the information storage module, and the cooperative loan issuance amount (Loanamt [ i ] of the financing security institution]＝{LoanAmt[1],LoanAmt[2],LoanAmt[3],...,LoanAmt[i]}), financial institution repayamut [ n ] repayment amount]＝{RepayAmt[1],RepayAmt[2],RepayAmt[3],...,RepayAmt[n]And pushing to an intelligent contract module. Then the intelligent contract module 332 receives the information pushed by the information processing module, recognizes the information as a partner institution qualification judgment application and pushes the information to the intelligent contract operation module; and receiving information of the intelligent contract operation module and pushing result information to the information storage module. And updating the state of the mechanism with the abnormal state as 'active exit', not allowing the execution of the deposit application with the active exit state, locking the operation of the mechanism deposit account, and not allowing the cooperative mechanism to carry out the transfer-out transaction. Finally, the intelligent contract operation module 333 receives the information sent by the intelligent contract module, accumulates the cooperative loan issuance amount of the financing guarantee institution, and calculates the loan total amount
Accumulating the repayment amount received by the financial institution to calculate the total repayment amount
Subtracting to obtain the institution loan residueThe amount of LoanBal ═ totaloamamm-TotalRepayAmt. Comparing the loan balance with the predicted loan size, i.e. LoanBal<Returning to normal if CashDept. mu. and LoanBal>CashDept mu, then returning an exception, and returning the result to the intelligent contract module.
S290: the application server sends the supervision result to the database server.
After the supervision result is obtained, the application server may send the supervision result to the database server to implement the subsequent steps.
S2100: the database server stores the supervision results.
After receiving the supervision result, the database server can store the supervision result into a database of the database server, so that the supervision result can be conveniently called in the subsequent process.
In some embodiments, the database server, upon receiving the supervision result, may determine whether the supervision result is a normal supervision result or an abnormal supervision result. And storing the supervision result when the supervision result is an abnormal supervision result. If the monitoring result is a normal monitoring result, the monitoring result is not processed so as to optimize the allocation of the storage resources.
In some embodiments, after storing the supervision result, the database server may further send the supervision result to the front-end device, so that the front-end device displays the supervision result, and a user can intuitively obtain a processing condition of the service of the user. The specific display mode may be, for example, display through a preset interface, or display through a voice or text form, which is not limited to this.
Based on the above description of the embodiment and the scenario example, it can be seen that, after receiving the service data, the front-end device may construct a digital signature for the service data, so as to ensure the authenticity of the data. And after the database server forwards the service data and the digital signature to the application server, the application server performs signature release verification on the digital signature. After the verification is passed, the service data can be stored in the block chain, so that each node in the service supervision system can effectively acquire the data stored in the block chain. Thereafter, the database server may send the supervision data to the application server, so that the application server calculates a corresponding supervision result, and sends the supervision result to the database server to store the supervision result. By the method, the communication among the service data is effectively realized, the data security is ensured, and the data of different organizations can be conveniently and effectively acquired when the service is supervised and audited, so that the service processing efficiency is improved, and the use experience of a user is improved.

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 the 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), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. 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 making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. 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 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.
From the above description of the embodiments, it is clear to those skilled in the art that the present specification can be implemented by software plus the necessary first hardware platform. Based on such understanding, the technical solutions of the present specification may be essentially or partially implemented in the form of software products, which may be stored in a storage medium, such as ROM/RAM, magnetic disk, optical disk, etc., and include instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to execute the methods described in the embodiments or some parts of the embodiments of the present specification.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the system embodiment, since it is substantially similar to the method embodiment, the description is simple, and for the relevant points, reference may be made to the partial description of the method embodiment.
The description is operational with numerous first or special purpose computing system environments or configurations. For example: personal computers, server computers, hand-held or portable devices, tablet-type devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like.
This description may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The specification may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
While the specification has been described with examples, those skilled in the art will appreciate that there are numerous variations and permutations of the specification that do not depart from the spirit of the specification, and it is intended that the appended claims include such variations and modifications that do not depart from the spirit of the specification.
