Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Before describing the technical solutions of the embodiments of the present invention, first, terms related to the embodiments of the present invention are described.
1. Block chaining techniques: also known as distributed ledger technology, the blockchain is originally derived from bitcoin, is a general ledger of all transactions maintained by each node in the bitcoin network, and is composed of a series of blocks linked back and forth, with a certain number of transfer transactions recorded in each block.
2, CA: the digital Certificate Authority (CA) is a key link for security of electronic transactions on the whole network, and is mainly responsible for generating, distributing and managing the identity authentication digital certificates required by all entities participating in online transactions. All parties of electronic transaction must possess legal identities, namely, a digital certificate authentication center structure issues a digital certificate, and all parties of transaction need to check the validity of the digital certificate of the other party in all links of transaction, so that the problem of user trust is solved.
3. And (3) abstract algorithm: the main characteristic of the message digest algorithm is that no key is needed in the encryption process, the encrypted data cannot be decrypted, and the same ciphertext can be obtained only by inputting the same plaintext data and performing the same message digest algorithm. The message digest algorithm has no key management and distribution problem, and is suitable for use in distributed network.
4. Block chain layer: the blockchain layer mentioned herein is a layer of encapsulation of the fabric java sdk with spring boot, providing functionality to interact with the fabric network and application layer.
5. Transaction systems such as bond issuing systems: the upper layer of the block chain layer carries out main business logic processing and interacts with the fabric network through the block chain layer.
The inventor finds that: the advantages of the blockchain mainly include 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 the tamper resistance is difficult to achieve on key information, namely: because the blockchain is different from the mechanism of the traditional transaction system, the blockchain can realize decentralization and has the characteristics of consensus and tamper resistance, but the functions of the traditional transaction system, such as storage and transmission of large data volume, are extremely difficult to realize, and the functions of the traditional transaction system are abundant, but are difficult to ensure in the aspects of data credibility and tamper resistance. Therefore, the inventor proposes a block chain-based data storage and verification processing scheme for bond issue, which utilizes the tamper-resistant property of the block chain to ensure the authenticity and credibility of the data of the transaction system, i.e. the scheme provided by the embodiment of the invention combines the two schemes, and stores the summary information of the important data of the transaction system onto the block chain by using an irreversible summary algorithm, thereby solving the above problems.
In particular, for a transaction system with multiple different parties, an important issue is how to ensure that the data of the system construction party is real, valid and not tampered. The invention ensures the authenticity and reliability of data based on the good consensus and tamper-proof characteristics of the blockchain system. Data of a transaction system is generally stored in a system construction party, while the data is opaque to storage and modification of other participants, but the data and the data can be well combined by using a blockchain, and the participants both hold digital certificates issued by CFCA to confirm the legal identities of the participants on the blockchain and share information through the blockchain. Although the blockchain can be decentralized, the storage of the data is not strong, so that the data of the traditional transaction system is stored on the blockchain in a summary mode, the verification is provided for the authority-adaptive participant, and the source data is still stored on the system builder.
The data storage and verification processing scheme for bond issuance based on block chain will be described in detail below.
Fig. 1 is a schematic flow chart of a data storage processing method for bond issuance based on block chain in an embodiment of the present invention, where nodes of bond issuance participants form a block chain network, as shown in fig. 1, the method includes the following steps:
step 101: the nodes of the bond issuing participator receive data storage requests in the bond issuing process and send the data storage requests to the first processing module; the data storage request comprises target storage data;
step 102: the first processing module detects whether target storage data belongs to pre-configured data needing to uplink 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 retrieval key identification into a system builder database, processing the target storage data according to a preset abstract algorithm to obtain corresponding abstract information, and sending the retrieval key identification and the abstract information to a first block chain module;
step 103: the first block chain module sends the retrieval key identification and the abstract information to a block chain network; the summary information is used for providing data verification for the bond issuing participants.
The method for storing and processing the bond issuance data based on the block chain ensures the safety and reliability of important and sensitive data in the bond issuance process, reduces the storage pressure and ensures the performance of the block chain.
The steps of the method for processing issuance of bond according to the embodiment of the present invention will be described in detail with reference to fig. 2.
In specific implementation, as shown in fig. 2, the product issued by the bond based on the blockchain according to the embodiment of the present invention is divided into a front-end presentation layer (which can be implemented by receiving a data storage request during bond issuance, receiving a data verification request during bond issuance, etc.), a background business logic layer (which can include the first processing module and the second processing module mentioned below), a connection blockchain layer (which can be implemented by sending the retrieval key identifier and the summary information to the first blockchain module, sending the data verification request to the second processing module, feeding back the verification result to the bond issuance participant node, etc.), a blockchain sdk layer (which can be the first blockchain module and the second blockchain module mentioned below), a blockchain layer (blockchain network), and a blockchain bond issuance system (which can be the bond issuance data storage module in the embodiment of the present invention), Check processing scheme) receives the front-end request and sends the front-end request to the background logic layer, and the background service logic layer finally calls the blockchain layer by connecting the blockchain layer to the access blockchain sdk layer.
The bond issuance 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, all the participants can log in for use, the participants use the certificates held by the participants as login certificates, and the transaction information digest on the blockchain is disclosed for all the participants.
2. Which data needs to be finally stored on the blockchain in a digest encrypted manner is configured. For example, after the issued bonds have been converted to an archived state, the distribution information (target stored data) needs to be stored in a block chain in a digest manner.
3. When the system transaction is finished and the confirmation data can not be modified any more, in addition to normal access to the database, the data (target storage data) also needs to be subjected to digest encryption. For example, before data is saved, whether the data needs to be encrypted in a summary manner is obtained from a configuration table (whether the target stored data belongs to pre-configured data needing to be linked in a summary manner), and the configuration table is configured with fields needing to be encrypted in a summary manner.
4. And sending the summary information and the retrieval key information (retrieval key identification) to a blockchain system through a blockchain connection layer to realize information uplink. The digest information is a character string generated by digest encryption of 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 block chain information (abstract information and retrieval key identification) is used as check backup, data in normal conditions are fed back to a user from a database, and when the user needs to check the reality and the non-modification of the data, the data abstract (abstract information) can be searched from the block chain through the retrieval information (retrieval key identification) and compared with the abstract information (calculated abstract information) generated by the data acquired by the database.
In implementation, the blockchain system (which may include a blockchain network formed by nodes of bond issuing participants) has an interface (which may include a first processing module and a second processing module) with the transaction system (which may include a first blockchain module and a second blockchain module), and can perform information interaction. The trading system discloses a digest encryption algorithm (digest algorithm) of the trading data for the bond issuing participant to verify the data, there being trade and compensation between the trading 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, and logs in the system after the user name, the password and the verification code are verified, and the system can display corresponding content and operation permission according to the role of the user.
2. Preparing for issuance: in this step, functions related to the preparation stage of issuing the bonds are mainly completed, and the functions include functions of creating bonds, building a sales group, managing issuing documents, posting bonds, and prompting for purchase requests by users such as issuers (issuers) and bookkeeping managers (managers) in the system. In one embodiment, the bond issuing participant node may comprise: issuer nodes, manager nodes, investor nodes, underwriter nodes, and the like.
3. Bond procurement: the system mainly completes related functions of the debt procurement stage, and comprises functions of filling and uploading procurement information in the system by users such as underwriters (underwriters) and investors (investors), monitoring real-time procurement conditions in the system by users such as distributors and bookkeeping managers, determining actual issue scale and the like.
4. Bond distribution: the method mainly completes related functions of the distribution stage of the bond, and comprises the functions of adjusting the distribution result by a bookkeeping manager, confirming the distribution result by a distributor and finishing the distribution, filing the bond by the distributor and the like.
The front end is accessed to the internet through a browser, the service logic layer is used for realizing the processing of service functions, and the database storage is also carried out on the layer; meanwhile, when the pre-configured data needing to be abstracted, the chain type data such as the key transaction data is stored in the blockchain after being encrypted by an abstraction algorithm. For example, embodiments of the present invention use a publisher archiving link, where after the bond distribution is completed, the publisher archives the results. The data storage and processing scheme for bond issuance based on block chains provided by the embodiment of the present invention is described by taking the filing operation involved in the bond issuance process as an example, and accordingly, for ease of understanding, the processing scheme for bond issuance verification based on block chains is also introduced.
1) When a user logs in, firstly, the service layer verifies the legality through the information of a user name, a password and a short message verification code, then, a block link interface is called to check the legality of a certificate of a mechanism where the user is located, and after the user logs in successfully, the content of a corresponding role is displayed on a page.
2) An issuer clicks filing operation on a page, a request (a data storage request during the filing operation) is sent to a business logic layer through an HTTP protocol, namely, the data storage request in the process of issuing the bond is received, the data storage request is sent to a first processing module (a business layer), the business layer firstly sets the bond to be in a final state (namely, a filing state, and the record cannot be changed any more afterwards), and bond information can be clicked to inquire a distribution detail information list of each organization.
3) The business layer uses the bond ID as a search key (a search key identifier, namely the search key identifier can be a bond identifier), forms a character string by recording the distribution detail list information (key transaction data) associated with the bond in a row manner, 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, then calculating MD5 value (summary information), namely detecting whether the target stored data belongs to pre-configured data needing to link the chain type in a summary 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, an interface service provided by a block chain connecting layer is called, namely, a retrieval key identifier and the abstract information are sent to a first block chain module, the connecting layer calls a block chain through an SDK interface provided by the block chain, the previous information (the retrieval key identifier and the corresponding abstract information) is written into an intelligent constraint of the block chain, and the retrieval key identifier and the abstract information are sent to a block chain network.
5) The method comprises the steps that an organization (any bond issuing participant) user inquires archived bonds through an inquiry interface provided by a block chain layer, namely, a data verification request in the bond issuing process input by the user is received, the display mode is the bond ID (retrieval key identification) and the MD value (summary information) corresponding to the associated distribution record, namely, the summary information is obtained from a block chain network according to the retrieval 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, the information can be subjected to MD5 calculation after base64 transcoding, and target storage data are obtained from a system builder database; and processing the target storage data according to a preset abstract algorithm, calculating to obtain corresponding abstract information, checking the information, namely comparing the calculated abstract information with the abstract information obtained from the block chain network, and obtaining a checking result according to the comparison result. The verification results may then be fed back to the bond issuing participant node by the second blockchain module.
