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 the technical solutions of the embodiments of the present invention are described, terms related to the embodiments of the present invention are described first.
The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in the blockchain system.
Blockchain design is a protective measure, such as (applied to) highly fault-tolerant distributed computing systems. Block chains enable mixed consistency. This makes the blockchain suitable for recording events, titles, medical records and other activities requiring the inclusion of data, identification management, transaction flow management and provenance management.
The block chain has the advantages that credit related information can be automatically recorded by means of a program algorithm and stored on each computer of the block chain network, and the block chain is transparent, non-falsifiable and low in use cost. The commercial bank may store and share the customer's credit information at the financial institution in encrypted form.
The inventor finds that: the existing verification mode and means mainly comprise that each system or product establishes a verification module and collects and stores related data, repeated construction exists, a large amount of data is repeated, standards are not unified, and the like. In addition, in the currently popular face-sweeping mode, due to the fact that products of various companies are different, points for acquiring data are different, algorithms are different, data are different, and if products of different companies are purchased among financial institutions and different systems of the financial institution, the same function can be repeatedly built and multiple sets of data can be generated, and verification cost is high.
In view of the above technical problems and the technical problems mentioned in the background art, the inventor proposes a service processing and verification method, system and verification node scheme based on a block chain, which adopts a block chain technology to realize various verifications in the financial industry such as the banking industry, and optimizes the verification method in the whole system; the big data analysis is added, the original simple password error, fake face-sweeping and the like can only be simply stopped in the bank, the application of a credit investigation system and the like is expanded, and the social security is improved and guaranteed. Specifically, a verification mode of the block chain is adopted, and the technical characteristics based on the block chain are suitable for various verification requirements of the current banking industry:
autonomy: the blockchain adopts a specification and a protocol (such as a set of public and transparent algorithms, for example, the method provided by the embodiment of the invention) based on the consistency of negotiation, so that all nodes in the whole system can freely and safely exchange data in a distrust environment, the trust of people is changed into the trust of machines, and any human intervention does not work.
The information is not falsifiable: once the information is validated and added to the blockchain, it is permanently stored, and unless more than 51% of the nodes in the system can be controlled simultaneously, the database modifications at the individual nodes are invalid, and therefore the data stability and reliability of the blockchain is extremely high.
Anonymity: because the exchange among the nodes follows a fixed algorithm, the data interaction is not required to be trusted (the program rule in the block chain can judge whether the activity is effective or not), and therefore, a counterparty does not need to generate trust by the counterparty in a public identity mode, and the method is very helpful for accumulating credit.
The service processing and verifying method, system and verifying node scheme are described in detail below.
Fig. 1 is a schematic flow chart of a service processing method based on a block chain in an embodiment of the present invention, where the method is applied to a system, and nodes of service processing participants form a block chain network; the service processing participant node comprises: the system comprises a plurality of different types of service handling clients, a verification device and at least one service handling system node; the authentication device comprises a plurality of authentication nodes, a plurality of authentication modes and user authentication data corresponding to each authentication mode are pre-deployed on each authentication node, as shown in fig. 1, the method comprises the following steps:
step 101: when receiving a service handling request of a user, each type of service handling client initiates a verification request and sends the verification request to a block chain network; the verification request comprises a user identifier, a verification mode identifier and corresponding user identity verification data to be verified;
step 102: each verification node searches for pre-deployed user identity verification data corresponding to the user identification and the verification mode identification from pre-deployed identity verification data according to the user identification and the verification mode identification sent by the service handling client through the blockchain network, compares the searched pre-deployed user identity verification data with the to-be-verified user identity verification data to obtain a comparison result, and sends the comparison result to the blockchain network;
step 103: a preset main verification node in the plurality of verification nodes obtains a verification result according to the proportion and the preset threshold value of the comparison result sent by the plurality of verification nodes through the block chain network, and sends the verification result to the block chain network;
step 104: and at least one service processing system node determines whether to continuously process the service processing request sent by the service processing client through the block chain network according to the verification result sent through the block chain network.
Compared with the prior art, the block chain-based service processing method provided by the embodiment of the invention optimizes the service handling verification method, reduces the verification cost, improves the verification safety and reliability, and further improves the service processing safety and reliability.

Meanwhile, for a product (service handling client) needing checking, the required checking of the block chain verifying device can be applied in real time through technical requirements of interface configuration, corresponding interface standard, encryption and the like, and a checking result is returned.
Step 101 is described next.
In specific implementation, the service handling and related verification mentioned in the embodiment of the present invention may include: the bank teller logs in the system, authorizes, and system managers log in the maintenance system and the like to verify the identity, and the client needs to input a password or a fingerprint, scan a face, check an iris and the like to confirm the identity and then transact business and the like when coming from the bank. From the above, verification involves parts internal and external: the interface is contained in the bank for business personnel, system operation and maintenance personnel and the like in the bank; the external aspect generally refers to clients, enterprises, co-workers with a cooperative relationship and the like handling business.
In particular, the products mentioned in fig. 2 may be ATMs, smart counters, safe deposit boxes, mobile banking, internet banking, etc.
In specific implementation, the user identifier may be a name, a number, and the like of the user, and the verification pattern identifier may be a number, and may be, for example, 001: a fingerprint verification mode; 002: a face recognition verification mode; 003: iris verification mode, etc. The user authentication data to be authenticated may be feature data obtained in real time in a user selection authentication mode, for example, if the user selects a face recognition authentication mode, the user authentication data to be authenticated may be face feature data of the user obtained in real time.
Third, next, the above step 102 is introduced.
In specific implementation, the pre-deployed authentication data may be a relational table, where the table includes all user identifiers, multiple authentication mode identifiers, and the pre-stored user authentication data corresponds to each authentication mode identifier. And after receiving the user identification and the verification mode identification, the verification node searches the user identification and the verification mode identification in the relation table, compares the searched pre-deployed user authentication data with the user authentication data to be verified to obtain a comparison result, and sends the comparison result to the block chain network.
Fourth, next, for convenience of understanding, the above step 103 and step 104 are introduced together.
In specific implementation, the main verification node may be preset, or a plurality of verification nodes may vote.
In an embodiment, the step of sending, by a preset master verification node in the multiple verification nodes, the verification result to the blockchain network according to the ratio and the preset threshold value of the comparison result sent by the multiple verification nodes through the blockchain network being consistent may include:
the main verification node receives comparison results sent by a plurality of verification nodes through a block chain network; determining a proportion of the plurality of comparison results that are consistent (e.g., ninety percent of the comparison results from the verification nodes are consistent); when the proportion that the comparison results are consistent is determined to exceed a preset threshold (for example, eighty percent), obtaining a verification passing result; sending the verification passing result to a block chain network;
the determining, by the at least one service processing system node, whether to continue processing the service transaction request sent by the service transaction client through the blockchain network according to the verification result sent through the blockchain network may include:
and when receiving the verification passing result sent by the blockchain network, at least one service processing system node processes the service processing request sent by the service processing client terminal through the blockchain network.
In specific implementation, the scheme of obtaining the verification result further improves the reliability of verification.
Fifth, next, some further preferred embodiments are presented.
In one embodiment, the service processing method based on the block chain may further include: the main verification node sends a verification result to the big data platform system; and the big data platform system is used for analyzing the verification result and sending the user information which is determined to have abnormal verification according to the analysis result to the credit investigation system.
In specific implementation, the verification result of the big data platform system can be analyzed, for example, the service can be analyzed for auditing (data delivery), customer behavior analysis (for example, the verification mode used by a certain customer, the verification habit, trend, etc. of the customer in the latest row), and abnormal verification analysis, for example, whether the service is stolen or not, etc.
When the block chain verification device is implemented specifically, data is led into a big data analysis platform system in batches, data analysis is carried out according to business requirements, data analysis materials are provided for all other systems, and for verification that abnormity is judged, agent information can be led into a credit investigation system according to rules (such as malicious use verification, stealing of other person information and the like), so that great contribution is provided for the safety of the whole society.
In one embodiment, the service processing method based on the block chain may further include: each verification node regularly receives updated user identity verification data sent by the input platform system; and updating the user authentication data which is pre-deployed on each authentication node according to the updated user authentication data.
After the block chain verification device is formed, the subsequent verification data is called by the product and is preposed, and the verification data is input into the block chain verification device through the verification data entry platform, so that the verification accuracy is further improved.
In summary, the technical scheme provided by the embodiment of the invention reduces the repeated development of the bank verification module, repeatedly shares data between products and systems, saves the verification cost and improves the safety and reliability of verification. Meanwhile, analysis of big data is achieved, and information needed by customer behaviors and the like is effectively extracted.
