Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Before describing the technical scheme of the embodiment of the present invention, the nouns related to the embodiment of the present invention are first described.
1. Blockchain techniques: also known as the distributed ledger technique, the blockchain originally originates from bitcoin and is a general ledger of all transactions maintained by each node in the bitcoin network, consisting of a series of blocks linked back and forth, each of which records a number of transfer transactions.
Ca: the digital certificate authority (Certificate Authority, CA) is a key element of the security of the whole online electronic transaction, and is mainly responsible for generating, distributing and managing the identity authentication digital certificates required by all entities participating in the online transaction. All parties to electronic transaction must have legal identity, namely, a digital certificate authentication center structure issues a digital certificate, and all parties to the transaction must check the validity of the digital certificate of the other party in all links of the transaction, thereby solving the problem of user trust.
3. Summary algorithm: the main characteristic of the message digest algorithm is that the encryption process does not need a key, and the encrypted data cannot be decrypted, and the same ciphertext can be obtained only by inputting the same plaintext data through the same message digest algorithm. The message digest algorithm has no key management and distribution problems and is suitable for use on a distributed network.
4. Blockchain layer: the blockchain layer referred to herein is a layer of encapsulation of fabric java sdk using spring boot, providing the functionality to interact with fabric networks and application layers.
5. Transaction systems such as bond issuing systems: and the upper layer of the block chain layer performs main business logic processing and interacts with the fabric network through the block chain layer.
The inventors found that: the advantages of the blockchain mainly embody decentralization, consensus and tamper resistance, but the blockchain is not suitable for storing large data, and the data storage of the traditional IT financial transaction system is not a problem, but tamper resistance is difficult for key information, namely: because the blockchain is different from the mechanism of the traditional transaction system, the blockchain can realize the decentralization and has the characteristics of consensus and tamper resistance, but the blockchain is extremely difficult to realize a plurality of functions of the traditional transaction system, such as the storage and transmission of large data quantity, and the functions of the traditional transaction system are rich, but are difficult to ensure in the aspects of data credibility and tamper resistance. Therefore, the inventor provides a block chain-based bond issuing data storage and verification processing scheme, the scheme utilizes the tamper-proof characteristic of the block chain to ensure that the data of a transaction system is truly and credible, namely the scheme provided by the embodiment of the invention combines the block chain issuing data storage and verification processing scheme and the block chain-based bond issuing data storage and verification processing scheme and the system solve the problems.
In particular, for transaction systems with multiple different parties, one of the important issues is how to ensure that the data of the party is truly valid and not tampered with. The invention ensures the true and reliable data based on the good consensus and tamper-proof characteristics of the block chain system. Data of a transaction system is generally stored in a system construction party, and the data is stored and modified opaque to other participants, but the data and the data can be well combined by using a blockchain, and the participants all hold digital certificates issued by the CFCA so as to confirm legal identity of the participants on the blockchain, and information is shared through the blockchain. Although the blockchain can be decentralised, the storage of the data is not strong, so the inventor stores the data of the traditional transaction system on the blockchain in a summary mode, provides verification for the party with right adaptation, and still stores the source data on the system building party.
The blockchain-based bond issuance data storage and verification processing scheme is described in detail below.
FIG. 1 is a flow chart of a blockchain-based bond issuance data storage processing method according to an embodiment of the present invention, wherein bond issuance participant nodes form a blockchain network, as shown in FIG. 1, and the method includes the steps of:
Step 101: the bond issuing participant node receives the data storage request in the bond issuing process and sends the data storage request to the first processing module; the data storage request comprises target storage data;
step 102: the method comprises the steps that a first processing module detects whether target storage data belongs to preconfigured uplink type data in a summary mode; when the target storage data is determined to belong to the uplink type data, storing the target storage data and the corresponding search key identification into a system constructor database, processing the target storage data according to a preset abstract algorithm to obtain corresponding abstract information, and sending the search key identification and the abstract information to a first block chain module;
step 103: the first block chain module sends the search key identification and abstract information to a block chain network; the summary information is used in providing data verification for bond issuing parties.
The block chain-based bond issuing data storage processing method provided by the embodiment of the invention ensures the safety and reliability of important and sensitive data in the bond issuing process, and reduces the storage pressure and the guarantee performance of the block chain.
The following describes in detail the steps involved in the bond issuing processing method according to the embodiment of the present invention with reference to fig. 2.
In specific implementation, as shown in fig. 2, the product issued by the bond based on the blockchain in the embodiment of the present invention is divided into a front-end presentation layer (which may be implemented by using the layer to receive a data storage request in the bond issuing process, receive a data verification request in the bond issuing process, etc.), a background service logic layer (which may include a first processing module and a second processing module mentioned below), a connection blockchain layer (which may be implemented by using the layer to send a search key identifier and summary information to the first blockchain module, send a data verification request to the second processing module, feedback the verification result to a bond issuing participant node, etc.), a blockchain sdk layer (which may be a first blockchain module and a second blockchain module mentioned below), a blockchain bond issuing system (which may be a bond issuing data storage and a verification processing scheme in the embodiment of the present invention) and then send the received front-end request to the background service logic layer, and the background service logic layer finally calls the blockchain layer through the connection blockchain layer sdk.
The bond issuing processing scheme based on the block chain provided by the embodiment of the invention mainly comprises the following steps:
1. The blockchain system is built, the participants can log in and use the same, the participants use certificates held by the participants as login certificates, and the transaction information on the blockchain is disclosed to all the participants.
2. Which data is configured to be ultimately stored in summary encrypted form on the blockchain. For example, after the issued bond has been transferred to an archiving state, it is necessary to store the sales information (target stored data) on the blockchain in a digest manner.
3. When the system transaction is finished, and the confirmation data is not modified any more, besides normal access to the database, digest encryption is also required for the data (target storage data). For example, before data is saved, whether the data needs digest encryption or not is obtained from a configuration table (whether the target storage data belongs to pre-configured data which needs to be uplink in a digest mode or not) and the configuration table is configured with the required digest encryption and the fields.
4. The summary information is sent to the blockchain system through the blockchain link layer together with the search key information (search key identification) to realize information uplink. The summary information is a character string generated by encrypting the summary of the data detail information (source data, i.e., target storage data), and the search key (search key identification) is a number associated with the detail information.
5. The blockchain information (abstract information and search key identification) is used as verification standby, normal condition data are fed back to a user from a database, and when the user needs to verify the reality of the data and is not modified, the abstract (abstract information) of the data can be searched from the blockchain through the search information (search key identification) and is compared with the abstract information (calculated abstract information) generated by the data acquired by the database.
In particular, the blockchain system (which may include a blockchain network formed by nodes of bond issuing participants) interfaces with the transaction system (which may include a first processing module and a second processing module), and may include a first blockchain module and a second blockchain module, and may perform information interaction. The transaction system discloses a digest encryption algorithm (digest algorithm) of the transaction data for use by bond issuing participants to verify data, and there is transaction and compensation between the transaction system and the blockchain system.
In specific implementation, the bond issuing process mainly comprises the following steps:
1. user login: the user logs in through the Internet browser, the user name, the password and the verification code are verified and then log in the system, and the system displays corresponding content and operation authority according to the user role.
2. Preparation for release: in this step, the functions related to the issuing preparation stage of the bond are mainly completed, and include functions such as bond creation, group establishment, issuing file management, bond announcement, and purchase requisition performed in the system by users such as a issuer (issuer) and a bookkeeping manager (manager). In one embodiment, the bond issuing party node may comprise: issuer nodes, manager nodes, sponsor nodes, underwriter nodes, etc.
3. Bond purchase: the method mainly completes the related functions of the buying stage of the bond, including the functions of filling in and uploading buying information in the system by users such as underwriters (underwriters), investors (investors) and the like, monitoring real-time buying conditions in the system by users such as issuers, bookkeeping managers and the like, determining the actual issuing scale and the like.
4. Bond distribution: the relevant functions of the bond selling stage are mainly completed, including the functions of a bookkeeping manager for adjusting the selling result, a distributor for confirming the selling result, a distributor for filing the bond, and the like.
The front end is accessed through a browser, accesses the Internet, the business logic layer is used for realizing the processing of business functions, and the database storage is also carried out on the layer; meanwhile, when the pre-configured data such as key transaction data is stored in a summary mode, the data is also stored in the blockchain after being encrypted by a summary algorithm. For example, the embodiment of the invention is used in a publisher archiving link, and after the bond distribution is finished, the publisher can archive the results. Taking archiving operation involved in the bond issuing process as an example, the bond issuing data storage processing scheme based on the blockchain provided by the embodiment of the invention is described, and correspondingly, for convenience of understanding, the bond issuing verification processing scheme based on the blockchain is also described.
1) When the user logs in, the service layer verifies the legality through the user name, the password and the short message verification code information, then the block link port is called to check the legality of the certificate of the organization where the user is located, after the user passes through the block link port, the user logs in successfully, and the content of the corresponding role can be displayed on the page.
2) The issuer clicks the archiving operation on the page, the request (the data storage request during the archiving operation) is sent to the business logic layer through the HTTP protocol, namely, the data storage request in the process of issuing the bond is received, the data storage request is sent to the first processing module (business layer), the business layer firstly sets the bond to the final state (i.e. the archiving state, and the record cannot be changed any more later), and the bond information can click to inquire the distribution detail information list of each institution.
3) The business layer uses the bond ID as a search key (the search key identifier may be a bond identifier), forms a character string of the sales details list information (key transaction data) associated with the bond in a manner of recording one line each, stores the character string in a local database (stored in a system builder database), and stores the target storage data and the corresponding search key identifier in the system builder database.
4) Converting the character string into base64 code, and then calculating MD5 value (abstract information), namely detecting whether the target storage data belongs to preconfigured uplink type data in an abstract mode; when the target storage data is determined to belong to the uplink type data, the target storage data is processed according to a preset abstract algorithm to obtain corresponding abstract information, interface service provided by a blockchain connecting layer is called, namely, a search key identifier and the abstract information are sent to a first blockchain module, the connecting layer calls a blockchain through an SDK interface provided by the blockchain, and the previous information (the search key identifier and the corresponding abstract information) is written into a blockchain intelligent constraint, namely, the search key identifier and the abstract information are sent to a blockchain network.
5) The user of the institution (any bond issuing participant) inquires the archived bonds through the inquiry interface provided by the blockchain layer, namely, the data verification request in the bond issuing process input by the user is received, and the display mode is that the bond ID (search key identification) and the MD value (abstract information) corresponding to the associated sale record are displayed, namely, the abstract information is acquired from the blockchain network according to the search key identification.
6) The front-end page provides an interface for inquiring the distribution detail character string, namely, a user is allowed to check the distribution detail character string, and MD5 calculation can be performed after base64 transcoding is performed on the information, namely, target storage data is acquired from a system construction side database; and processing target storage data according to a preset abstract algorithm, calculating to obtain corresponding abstract information so as to verify information, namely comparing the calculated abstract information with abstract information obtained from a blockchain network, and obtaining a verification result according to a comparison result. The verification result may then be fed back to the bond issuing party node through a second blockchain module.
