The present disclosure relates to the technical field related to data processing, and in particular, to a management method, apparatus, and system for improving ticket transaction security.

Background technique

The commercial draft is issued by the drawer, and the entrusted payer unconditionally pays the determined amount to the payee or the holder's bill on the specified date. The bill itself must be stamped with a valid seal before it can be circulated.

Commercial bill of exchange is one of the main types of bills, with both payment settlement and short-term financing functions, meeting the payment needs of enterprises, broadening financing channels, reducing financial expenses, improving the payment service level of commercial banks, strengthening asset and liability management, and enriching central bank currency. Policy instruments have a very important role to play.

In recent years, with the continuous improvement of China's financial electronic level and the improvement of financial infrastructure, in the bill business, bank drafts, bank drafts and checks have been electronically implemented to varying degrees, and the safety and efficiency have been greatly improved. However, relatively speaking, the electronic pace of commercial bills is lagging behind, and its business processing basically adopts traditional manual and paper methods, with low efficiency and high risk, which is not conducive to the further development of commercial bills. Since 2005, although some domestic commercial banks have actively explored and tried on the electronic use of electronic bills and electronic bills, the lack of a unified centralized bill registration mechanism and cross-bank trading platform has greatly restricted business development.

With the development of domestic bill business and bill market, how to unify, credibility and high efficiency of electronic commercial bills is the core issue to be considered. At present, many financial enterprises and units have proposed to establish a unified electronic commercial bill of exchange information management service platform that receives, stores and sends electronic commercial bills of data data, and provides services related to electronic commercial bills currency payment and fund liquidation behavior, relying on network and computer technology. To solve these problems. However, the current public network environment and storage mechanism are not very sound, and there are problems such as information fraud and loss.

The Electronic Commercial Draft System is built and managed by the People's Bank of China. It provides services related to electronic commercial money order currency payment and fund liquidation behavior, and provides paper commercial money order registration inquiry service and commercial money order transfer discount public quotation service. Business processing platform.

The electronic commercial bill of exchange business processing function module is the core module of the electronic commercial bill of exchange system. The electronic commercial bill of exchange business processing functions mainly include:

1. Answer (the other party sends a telegram (short for electronic commercial bill of exchange), how to sign);

2, holding a ticket inquiry (how to query holding the bill);

3. Prompt payment (how the ticket holder withdraws the ticket after the bill expires);

4, discount (the bill is not expired, the ticket holder is eager to recover the money how to operate);

5. Endorsement (how to transfer the electricity ticket to others);

6, ticketing (how to send a ticket to the other party);

7. Status of the bill (by the enterprise online banking to answer, issue, endorse, prompt the status of the bill during the payment operation).

However, the prior art has the following disadvantages: trader (system trader, system participant or user) and commercial bill of exchange information have low integrity and transparency, may have problems such as trade background fraud, and have high transaction risk; if cyber attack Or the storage is abnormal, the information is falsified, lost, etc.; the transaction process is not standardized, the record is incomplete, there is a phenomenon that the electronic commercial bill of exchange endorsement is discontinuous, one ticket is more sold; multiple complex audits are required, the review is difficult and the cost is high, and the efficiency is low. The transaction process relies too much on intermediaries.

Therefore, there is a need for a new management method, apparatus and system for improving the security of ticket transactions.

Detailed ways

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be embodied in a variety of forms and should not be construed as being limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more complete and complete, To those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In addition, the drawings are merely schematic representations of the present disclosure and are not necessarily to scale. The same reference numerals in the drawings denote the same or similar parts, and the repeated description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily have to correspond to physically or logically separate entities. These functional entities may be implemented in software, or implemented in one or more hardware modules or integrated circuits, or implemented in different network and/or processor devices and/or microcontroller devices.

First, some of the terms mentioned in the present disclosure will be explained.

Block Chains: Blockchains are new application models for computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. The so-called consensus mechanism is a mathematical algorithm for realizing trust and acquiring rights between different nodes in the blockchain system. Blockchain - the original blockchain - is a decentralized database that contains a list of blocks, with continuously growing and well-organized records. Each block contains a timestamp and a link to the previous block: the design blockchain makes the data untamperable - once recorded, the data in one block will be irreversible.

Consortium Block Chains: A plurality of pre-selected nodes are designated as billers within a group, and the generation of each block is determined by all pre-selected nodes (pre-selected nodes participate in the consensus process). Other access nodes can participate in the transaction, but the accounting process is essentially (essentially managed accounting, just become distributed accounting, how many pre-selected nodes, how to determine the biller of each block becomes the blockchain The main risk point), anyone else can use the blockchain open API (Application Programming Interface) for qualified queries.

The characteristics of the blockchain include:

Decentralization: Due to the use of distributed accounting and storage, there is no centralized hardware or management organization, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance functions in the whole system. .

Openness: The system is open. In addition to the private information of the parties to the transaction being encrypted, the data of the blockchain is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface, so the whole system The information is highly transparent.

Autonomy: Blockchain adopts consensus-based specifications and protocols (such as a set of transparent and transparent algorithms) to enable all nodes in the entire system to exchange data freely and securely in a trusted environment, so that the "people" want to trust Become a trust in the machine, and any human intervention does not work.

Information cannot be tampered with: once the information is verified and added to the blockchain, it is stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the block The data stability and reliability of the chain is extremely high.

Anonymity: Since the exchange between nodes follows a fixed algorithm, the data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is valid), so the counterparty does not need to open the identity to let the other party generate itself. Trust is very helpful for the accumulation of credit.

The blockchain core technologies include:

The first one is called the distributed ledger, which means that the transaction accounting is completed by multiple nodes in different places, and each node records the complete accounts, so they can all participate in supervising the legality of the transaction, and they can also jointly testify. Unlike traditional centralized accounting schemes, no single node can record accounts separately, thus avoiding the possibility of a single biller being controlled or being bribed to account for false accounts. On the other hand, since there are enough billing nodes, in theory, unless all nodes are destroyed, the accounts will not be lost, thus ensuring the security of the account data.

The second is called asymmetric encryption and authorization technology. The transaction information stored in the blockchain is public, but the account identity information is highly encrypted and can only be accessed if the data owner authorizes it, thus ensuring the data. Security and personal privacy.

The third is called the consensus mechanism, which is how to reach a consensus among all the accounting nodes to determine the validity of a record. This is both a means of identification and a means of preventing tampering. The blockchain proposes four different consensus mechanisms that apply to different application scenarios and strike a balance between efficiency and security. Taking Bitcoin as an example, the proof of workload is used. Only when the accounting node of the whole network exceeds 51% is controlled, it is possible to forge a record that does not exist. This is basically impossible when there are enough nodes to join the blockchain, thus eliminating the possibility of fraud.

The last technical feature is called smart contracts, which are based on these trusted, non-tamperable data that can be automated to execute some predefined rules and terms. In the case of insurance, if everyone's information (including medical information and risk-generating information) is authentic, it is easy to automate claims in some standardized insurance products. A smart contract is a set of commitments defined in digital form, including agreements on which contract participants can execute these commitments.

Distributed: Distributed computing is a computer science that studies how to divide a problem that requires a very large computational power into many small parts, then distributes those parts to many computers for processing, and finally combines these calculations. Get up to get the final result. Distributed network storage technology is the decentralized storage of data on multiple independent machines. The distributed network storage system adopts a scalable system structure, which utilizes multiple storage servers to share the storage load and locates the storage information by using the location server, which not only solves the bottleneck problem of the single storage server in the traditional centralized storage system, but also improves the reliability of the system. Sex, usability and scalability.

API: The application programming interface is a predefined function that provides the ability for applications and developers to access a set of routines based on a piece of software or hardware without having to access the source code or understand the details of the internal workings.

Discount: Discount means that after the forward draft is accepted, the holder of the bill is transferred in the discount market before the bill has not expired. After the deductor deducts the discount interest, the ticket will be paid to the behavior of the person or the bank purchase will not expire. Bill business.

Endorsement: Endorsement refers to the behavior of the ticket holder to record the relevant matters and sign the bill on the back of the bill of exchange or on the sticky note for the purpose of transferring the bill of exchange right or granting a certain bill of exchange rights.

Acceptance: that is, promised redemption, is an act of the payer signing on the bill of exchange indicating that he promises to assume the payment obligation in the future when the bill of exchange expires. The acceptance act only occurs in the relevant activities of the forward draft. Promissory notes, cheques and demand drafts are unlikely to be accepted.

In step S110, user information management and membership authentication are performed based on the blockchain technology.

Among them, the Block Chain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology and infrastructure of Bitcoin. A blockchain is a string of data blocks generated using cryptographic methods. Each block contains information about a bitcoin network transaction for verifying the validity of its information (anti-counterfeiting) and generating the next block. In a narrow sense, a blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and cryptographically guaranteed non-tamperable and unforgeable distributed ledgers. Broadly speaking, blockchain technology uses blockchain data structures to validate and store data, use distributed node consensus algorithms to generate and update data, and use cryptography to ensure data transmission and access security, using automated scripts. The code consists of a smart contract to program and manipulate data in a completely new distributed infrastructure and computing paradigm. Blockchain design is a protection measure, such as (applied) to a highly fault-tolerant distributed computing system. The blockchain makes mixing consistency possible. This makes the blockchain suitable for recording events, headlines, medical records and other activities that require data collection, identity management, transaction process management and provenance management.

4. The system generates a blockchain electronic commercial bill of exchange and assigns a unique identifier;

5. Publish information to other nodes.

For specific implementation, reference may be made to the description of FIG. 5 below.

In step S230, the transaction process security is improved.

In the embodiment of the present invention, the improving the security of the transaction process may further include the following steps:

1. Develop business processes;

2. Docking legal and regulatory authorities;

3. Record transaction status and bill status;

4. Publish information to other nodes.

For specific implementation, reference may be made to the description of FIG. 6 below.

FIG. 4 schematically illustrates a flow chart for improving user security in an exemplary embodiment of the present disclosure. As shown in FIG. 4, the improving user security may include the following steps.

In step S211, when the user performs system registration, the user type is determined and the user information is acquired.

In this step, user information is obtained: when the user performs system registration, the user fills in the registration information and submits the registration application, first determines the user type, and if it is XX (for example, an e-commerce platform), the supplier displays its qualification information to the user for confirmation. If not the XX supplier, guide the user to submit qualification information. The user information is then saved and the member number is assigned to the user.

In step S212, the member management service of the blockchain is invoked to guide the user to generate the local public/private key.

In this step, the user is assigned a unique identifier (the unique identifier here is the same as the member number of the above step S211, and is consistent with each other): the member management service of the blockchain is invoked through the member management API interface to provide the system trader with The member registration function guides the user to generate a local public/private key.

It should be noted that the registration information in step S211 is to register basic information at the management system level, the registration function in step S212 is to provide a blockchain registration service for the user, and the blockchain has a member management service, and the local service is generated through the service. Public/private key used to log in to the system.

In step S213, the identity authentication, the credit information reference, and the temporary audit group review and evaluation.

After reviewing the user and its registration information into the audit stage in this step, the user is reviewed and rated. The main audit methods may include: identity authentication, credit information reference, and temporary audit group audit evaluation results. Among them, the identity authentication is mainly to verify the identity of the user, check whether the information submitted by the user and the uploaded document information are true; the members of the temporary audit group are selected from the members of the audit group according to the domain and industry of the user, and the temporary audit group comprehensive user credit information. The information and trade background are reviewed and evaluated, and the results of the consensus review are given. Users can be granted different system privileges based on different ratings.

The rating result (or the audit result) may include, but is not limited to, a high-quality user (direct transaction authority), a general user (a transaction authority after applying for authorization), a high-risk user (a transaction authority cannot be), and the like.

In step S214, the data encryption public key/private key is allocated, the user information and the audit result are written into the blockchain and the user admission information is issued to other nodes.

In this step, the user information is written/recorded to the blockchain: the data encryption public key/private key is assigned, the user information and the audit result are written into the blockchain and the user admission information is issued (the user access information here is only the user) Admission notices this information) to other nodes.

It should be noted that the local public/private key in step S212 is used to encrypt the user information, and the data encryption public key/private key allocated in step S214 is used to encrypt the data, instead of being the user. Information encryption.

FIG. 5 schematically illustrates a flow chart for improving ticket security in an exemplary embodiment of the present disclosure. As shown in FIG. 5, the improving ticket security may include the following steps.

In step S221, the system receives the transaction request issued by the user and performs user qualification verification, and receives the user commercial money order information after verification.

In this step, the bill is verified, for example, a commercial bill source: the system receives the transaction request issued by the user and performs user qualification verification, and after receiving the verification, receives the user bill, such as commercial bill of exchange information.

In step S222, a temporary audit group is formed by screening from the audit group members according to the field, region, and the like of the bill.

In this step, the (temporary) audit team is formed (the audit team is extracted from the expert group, not fixed): the audit rating work is carried out by the temporary audit team, and the members of the temporary audit team are based on the field of the bill (the company can be issued according to the bill) Industry division), geographical area, etc. are composed of members of the audit team.

In step S223, an audit model may be formed according to the adjustment of the basic model provided by the system.

In this step, an audit model is built: the audit model can be adjusted based on the underlying model provided by the system. Among them, the basic audit model can include basic financial information, production and operation, financing, bank loans and credit status, and the weight of each item can be adjusted. The base model can include all the options, and then assign the weight ratio reasonably. Based on this, the partial weight ratio can be adjusted to 0 according to actual needs, and the weight can be ignored.

In step S224, the model evaluation results of the members of the interim review team are weighted and averaged to obtain an audit score.

The review score is performed in this step. For example, the model evaluation results of the members of the interim review team can be combined and weighted averaged to arrive at a final rating result. Among them, the weighted average calculation method may be: rating score (or audit score) = (model score per item * weight);

In step S225, the merchant ticket content and the audit score are written into the blockchain.

In this step, the trade ticket information is written to the blockchain (here, it can refer to all the information on the trade ticket (short for commercial draft)): after reviewing the rating, the trade ticket content and the rating result are written into the blockchain, and the generation zone is generated. Blockchain electronic commercial money orders and assign unique identifiers; and issue trade ticket information to their nodes. The business ticket information and the rating result are written into the blockchain database, and then the electronic commercial bill of exchange template is configured on the front end, and each stored information record is captured by the application, which is an electronic commercial bill of exchange.

FIG. 6 schematically illustrates a flow chart for improving the security of a transaction process in an exemplary embodiment of the present disclosure. As shown in FIG. 6, the improving transaction process security may include the following steps.

In step S231, the business expert configures the business rules on the smart contract service according to the corresponding business logic.

In this step, the business rules are configured: the transaction process relies on the intelligent contract service of the blockchain, and the business expert configures the business rules on the smart contract service according to the corresponding business logic, and stores them in the blockchain contract state storage.

In step S232, the legal and regulatory regulatory agency is docked, and the legal and regulatory supervision model is configured to influence the whole process of the transaction behavior.

In this step, the transaction process is regulated by law: docking legal and regulatory authorities, configuring legal and regulatory supervision models, affecting the whole process of transaction behavior, and solving the legality of basic transactions. For example, first set up several models according to the scope of laws and regulations, and point out the keywords, then search the transaction information according to the keywords, and the search results match the model.

In step S233, the system trader initiates a transaction request through the transaction initiation API, and invokes different smart contract services depending on the transaction type.

In this step, the intelligent transaction is realized: the system trader initiates the transaction application/request through the transaction initiation API of the blockchain, and calls different smart contract services according to the transaction type (for example, acceptance, discount).
