Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart illustrating a financial monitoring method according to an embodiment of the present invention, which is applicable to tracking and monitoring financial transactions, and the method can be executed by a financial monitoring apparatus. As shown in fig. 1, the method specifically includes the following steps:
When people perform illegal transactions, in order to cover the illegal behaviors, transaction requests are generally required to be forwarded by nodes in the blockchain network for multiple times and are finally transmitted to a target node, so that when financial transactions are supervised, transaction tracing needs to be performed on each node in the blockchain network, the target node is determined, and financial supervision is performed on the target node. A client node is added in a block chain, a worker can initiate a transaction from a client, a probe is deployed in the client node, namely the client node can be a probe node, and the probe node can acquire transaction information of each node in a block chain network. That is, probe nodes are deployed on the public link, and the probe nodes can collect transaction information of each server node in the public link network by using a node discovery mechanism in the public link technology.
The staff may preset one or more seed nodes from the plurality of nodes, for example, the staff may analyze each server node in advance, search for a suspicious node, use the suspicious node as a seed node, and use the suspicious node as a node that may perform illegal transactions. With the seed node as the initial node for the transaction request, the transaction request may be first issued to the seed node by the client node. The client node acts as a probe node and requests transaction information from the seed node, which may include the user account number of the transaction initiator, the time when the transaction request was received, the size of the received data packet, etc. After receiving the transaction request, the seed node can forward the transaction request in the blockchain network, the node receiving the transaction request can forward the transaction request again until the last node does not forward the transaction request, the node receiving the transaction request finally is a target node, and the target node is a node needing to be supervised. Through recursive acquisition, the probe node finally obtains the transaction information of each node receiving the transaction request in the public link network and the transaction link of the transaction request, and the forwarding process among the server nodes is the transaction link from the seed node to the target node of the transaction request.
In this embodiment, optionally, the obtaining, by a probe node disposed in the blockchain network, a transaction link of the transaction request from the seed node to the target node and transaction information of any node in the transaction link includes: sending a transaction request to a preset seed node through a client, and acquiring transaction information of the seed node based on probe nodes deployed in a block chain network; judging whether the first-order neighbor node exists in the seed node, if so, sending a transaction request to the first-order neighbor node by the seed node, and acquiring transaction information of the first-order neighbor node through the probe node; judging whether a first-order neighbor node has a second-order neighbor node, if not, determining the first-order neighbor node as a target node, and the transaction information of the first-order neighbor node as the transaction information of the target node; and determining a transaction link from the seed node to the target node of the transaction request according to the node forwarding sequence of the transaction request in the block link network.
Specifically, the staff member sends a preset transaction request from the client node to one seed node, for example, the transaction request may be a transfer request. The method comprises the steps that a probe is deployed in a client node, the client node is deployed in a block chain network, namely the client node deployed in the block chain network can be used as the probe node, and when a client sends a transaction request to a seed node, the client node serves as the probe node to acquire transaction information of the seed node. For example, the probe node may obtain the content of the transaction request received by the seed node, the user account number of the transaction initiator, the time when the transaction request is received, the size of the received data packet, and the like. Each node in the blockchain corresponds to a unique user account number which can be used for initiating a transaction. Each server node in the blockchain network may be connected to each other to form a network topology. Each node can determine its own neighbor node according to the connection sequence, for example, if the node a is connected to the node B, and the node B is connected to the node C, then the node a is an upper node of the node B, the node B is a neighbor node of the node a, the node B is an upper node of the node C, and the node C is a neighbor node of the node B.
After the seed node receives the transaction request, whether the seed node has a neighbor node or not is determined, and the neighbor node of the seed node is a first-order neighbor node. And if so, forwarding the transaction request to the first-order neighbor node by the seed node. After the first-order neighbor node receives the data packet of the transaction request, the probe node acquires the transaction information of the first-order neighbor node. The probe node can determine a transmission process of the transaction request forwarded from the seed node to the first-order neighbor node according to the transaction information of the seed node and the first-order neighbor node. After the first-order neighbor node receives the transaction request, whether the first-order neighbor node has a neighbor node of the first-order neighbor node can be judged, and the neighbor node of the first-order neighbor node is a second-order neighbor node. If the first-order neighbor node does not exist, the first-order neighbor node is determined to be the last node, namely the first-order neighbor node is the target node of the transaction request, the transaction object of the transaction request is the user of the first-order neighbor node, and the transaction information of the first-order neighbor node is the transaction information of the target node. The probe node acquires the transaction information of each node and determines the forwarding sequence of the transaction request among the nodes. And obtaining a transaction link of the transaction request from the seed node to the target node according to the forwarding sequence. The transaction link is a path of the transaction request between nodes, for example, the transaction request starts from the client, passes through the seed node first, and then passes through the target node, and completes the transaction. The beneficial effect of the arrangement is that the transaction link of the transaction request can be obtained by deploying the probe node, the target node which finally receives the transaction request is determined, the transaction request is convenient to track, the target node is supervised, the intermediate nodes are prevented from being supervised, the target node is omitted, and the efficiency and the precision of financial supervision are improved.
In this embodiment, optionally, after determining whether the first-order neighbor node has the second-order neighbor node, the method further includes: if the first-order neighbor node has a second-order neighbor node, the first-order neighbor node sends a transaction request to the second-order neighbor node, and transaction information of the second-order neighbor node is acquired through the probe node; and judging whether a third-order neighbor node exists in the second-order neighbor node, if not, determining the second-order neighbor node as a target node, and the transaction information of the second-order neighbor node as the transaction information of the target node.
Specifically, after the transaction request is sent to the first-order neighbor node, whether the first-order neighbor node has a second-order neighbor node is determined. If the second-order neighbor node exists, the first-order neighbor node forwards the transaction request to the second-order neighbor node, and the probe node acquires the transaction information of the second-order neighbor node. And judging whether the second-order neighbor node has a neighbor node, wherein the neighbor node of the second-order neighbor node is a third-order neighbor node, if not, determining the second-order neighbor node as a target node, and the transaction information of the second-order neighbor node is the transaction information of the target node. The transaction link of the transaction request is that the transaction request is sent to the seed node from the client node, forwarded to the first-order neighbor node by the seed node, and forwarded to the second-order neighbor node by the first-order neighbor node, so as to complete the transaction. If the third-order neighbor node exists, the second-order neighbor node sends the transaction request to the third-order neighbor node, the probe node acquires the transaction information of the third-order neighbor node and judges whether the fourth-order neighbor node exists in the third-order neighbor node or not until the transaction request is sent to the target node. The beneficial effect who sets up like this lies in, can traverse each neighbour node, and the accurate target node of finding avoids the node to miss, practices thrift manpower and time, improves the efficiency and the precision of financial supervision.
The probe node establishes a topological graph of the monitoring network around the seed node, continuously collects transaction information in the monitoring network, and public link transactions are transmitted in a network layer in a flooding mode, namely the seed node firstly forwards a transaction request to a neighbor node, and then the neighbor node continuously forwards the transaction request to the own neighbor node. And repeating the steps until the transaction request is transmitted to the target node in the public chain network, so as to trace the source of the transaction of the node.
And step 120, acquiring the equipment information of the equipment IP receiving the transaction request through a data flow probe deployed in the local area network.
After the transaction request is forwarded on the transaction link, the traffic analysis function of a DPI (Deep Packet Inspection) device and a web crawler are deployed to obtain device information associated with the transaction request in the local area network, for example, the local area network may be a metropolitan area network, a data traffic probe may be deployed in a machine room of an operator to obtain the device information of the transaction request, and the device information may be information of a device IP that has received or forwarded the transaction request. The transaction information can be obtained through keywords in the transaction request, the device IP which receives the transaction request is determined, and the data packet of the transaction request received by each device IP is obtained. By analyzing the data packet, the time when each device IP receives the data packet, the size of the data packet, and the like can be obtained. Each device IP corresponds to a unique user account which is consistent with the user account in the block chain link point. The device information of the transaction request may include an IP address of the device that received the transaction request, a time at which the transaction request was received, a user account number at which the transaction request was received, a size of the received data packet, and the like.
And step 130, determining a target device IP corresponding to the target node based on a preset information comparison condition according to the transaction information and the device information so as to realize supervision on the target device IP.
After the transaction link and the transaction information of the transaction request in the blockchain and the device information in the local area network are obtained, the transaction information and the device information can be compared, and the transmission sequence of the transaction request among the device IPs is determined according to a preset information comparison condition. And determining the equipment IP corresponding to the target node according to the sequence of the equipment IP transmission transaction requests. And taking the equipment IP corresponding to the target node as the target equipment IP, and finishing the tracking of the target equipment IP. The staff can perform financial supervision on the target device IP, for example, the staff can perform comprehensive analysis on the transaction data of the target device IP to determine whether there is illegal behavior such as high-frequency transaction or large-amount transaction, thereby realizing the supervision on the target device IP.
In this embodiment, optionally, the transaction information includes a user account of a transaction initiator of the node, and the device information includes a user account of a transaction initiator of the device IP; correspondingly, according to the transaction information and the device information, based on the preset information comparison condition, determining the target device IP corresponding to the target node, including: comparing the user account in the transaction information of the target node with the user account in the IP equipment information of any equipment; and if the user account in the equipment IP equipment information is consistent with the user account in the target node transaction information, determining that the equipment IP is the target equipment IP corresponding to the target node.
Specifically, the user account is an account for a user to initiate a transaction, and each server node receives one user account when receiving a transaction request, for example, the seed node sends a transaction request to the first-order neighbor node, and the first-order neighbor node may receive the user account of the seed node as a transaction initiator. For another example, if the first IP sends a transaction request to the second IP, the second IP can obtain the account of the transaction initiator of the first IP. And acquiring the transaction information of each node in the probe node, acquiring the user account of the transaction initiator of each node, and acquiring the user account of the transaction initiator of each equipment IP address in the local area network. And comparing the user account number of each node with the user account number of each equipment IP address, determining a transaction link of the transaction request in the local area network according to the transaction link and the user account number of the node, namely sequencing the equipment IP addresses according to the transaction link of the node, determining the IP address of the transaction request transmitted from the IP address of the seed node to the target node, and determining the equipment IP corresponding to the target node. Or directly searching the user account in the transaction information of the target node, and searching the user account consistent with the user account of the target node from the device information of the device IP, wherein the device IP corresponding to the user account is the target device IP. The method has the advantages that the public chain account has IP address anonymity, only the virtual account address can be identified after the target node is determined, the actual service IP address bound by the virtual account address cannot be determined, and the practical effect on supervision cannot be achieved. The real IP address of the target node in the local area network can be obtained through the user account of the transaction initiator, and block chain project supervision of financial application is achieved.
In this embodiment, optionally, after determining a target device IP corresponding to the target node based on a preset information comparison condition according to the transaction information and the device information, the method further includes: and acquiring historical transaction information of the IP of the target equipment, and auditing the historical transaction information according to a preset transaction supervision rule.
Specifically, after the target device IP address corresponding to the target node is determined, historical transaction information of the target device IP address is obtained. Transaction supervision rules are set in advance, for example, keywords of illegal transactions are set. And searching whether the transaction containing the key words exists in the historical transaction information or not according to transaction supervision rules, and if so, determining that the illegal transaction exists in the IP of the target equipment, thereby realizing the examination and verification of the historical transaction information. For example, the maximum value of the transaction amount may be set, whether the historical transaction amount of the target device IP exceeds the maximum value of the transaction amount is determined, and if yes, it is determined that the target device IP has a behavior of large-amount transaction. The method has the advantages that any transaction information of the IP of the target equipment can be audited, the manual auditing process is reduced, and the efficiency and the precision of financial supervision are improved.
Based on a node protocol identification technology of a block chain P2P (Peer-to-Peer, Peer-to-Peer network), and combining technologies such as a web crawler and data traffic acquisition and analysis, bidirectional result tracing is performed on transactions on the chain and data in a local area network, namely, the source and the final destination of funds among accounts are traced, an actual IP address and a topological graph in the transaction process are determined, and penetrating supervision is realized.
According to the technical scheme of the embodiment, the transaction request is sent to the seed node through the block chain, and then the seed node gradually sends the transaction request to the last target node. And obtaining the transaction information of each node and the transaction link of the transaction request among the nodes according to the probe nodes deployed in the block chain. And acquiring the actual communication process of the transaction request in the local area network through the data flow probe, namely determining the equipment information of the transaction request received. And comparing the transaction information with the equipment information, determining that the equipment IP corresponding to the target node is the target equipment IP, and supervising the transaction on the target equipment IP. The problem that in the prior art, the transaction request cannot be automatically tracked is solved, manpower and time are saved, the transaction of the IP of the target equipment is supervised by determining the IP of the target equipment, and the efficiency and the precision of financial supervision are improved.
Example two
Fig. 2 is a flow chart of a financial monitoring method according to a second embodiment of the present invention, which is further optimized based on the second embodiment. As shown in fig. 2, the method specifically includes the following steps:
The transaction information may include the time when the node receives the transaction request, and the device information may include the device IP address when the transaction request is received and the time when the device IP receives the transaction request. If the transaction information and the device information do not include the user account, the time when each node receives the transaction request may be compared with the time when each device IP receives the transaction request. And determining the equipment IP corresponding to each node according to the time of receiving the transaction request. And sequencing the equipment IPs according to the transaction link of the transaction request in the blockchain network to obtain the communication process of the transaction request in the local area network. And obtaining the equipment IP corresponding to the target node according to the sequencing of the equipment IPs. Or directly comparing the time when the target node receives the transaction request with the time when the device IP receives the transaction request, and searching the target device IP corresponding to the target node. In the process of comparing the receiving time, if the time when only one device IP receives the transaction request is consistent with the time when the target node receives the transaction request, the device IP is determined to be the target device IP. The beneficial effect of the arrangement is that under the condition that the account number of the user cannot be known, the IP of the target device can be determined through the receiving time of the transaction request, the transaction can be tracked, the flexibility and the efficiency of financial supervision are improved,
in this embodiment, optionally, the transaction information includes a size of a data packet received by the node; the device information includes the size of a data packet received by the device IP; correspondingly, after comparing the time when the transaction request is received by the target node with the time when the transaction request is received by any device IP, the method further comprises the following steps: if the time that at least two equipment IPs receive the transaction request is consistent with the time that the target node receives the transaction request, comparing the size of the data packet received by the target node with the size of the data packet received by the at least two equipment IPs; and determining the device IP with the size consistent with the size of the data packet received by the target node in the at least two device IPs as the target device IP corresponding to the target node.
Specifically, the transaction information may further include a size of a data packet received by the node, and the device information may further include a size of a data packet received by the device IP. After the comparison of the receiving times, it may happen that the time for receiving the transaction request by the multiple device IPs is the same, for example, the device information includes the device information of the multiple transaction requests, that is, when the device information of the transaction request is obtained, the device information of other transaction requests may also be obtained. Different transaction requests may be initiated at the same time, and the device IP corresponding to the node cannot be determined by the receiving time of the transaction request. In order to further screen the device IPs, the size of the data packet received by each device IP may be obtained, and the size of the data packet received by the device IP is compared with the size of the data packet received by the node. For example, if there are two device IPs that receive the transaction request at the same time as one node receives the transaction request, the sizes of the data packets received by the two device IPs and the size of the data packet received by the node are respectively compared. And determining the device IP which is consistent with the size of the data packet received by the node from the two device IPs, and determining the device IP as the device IP corresponding to the node. The time when the target node receives the transaction request can be directly compared with the time when each device IP receives the transaction request, and if a plurality of device IPs which are consistent with the time when the target node receives the transaction request exist, the target device IP can be directly determined from the device IPs. The method has the advantages that the IP of the target equipment is screened according to the time and the size of the data packet, and the determining precision of the IP of the target equipment is improved. In step 220, transaction information of other transactions may appear, and through secondary screening, the device IP related in other transaction processes can be prevented from being used as the target device IP, so that the accuracy of financial supervision is effectively improved.
