Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention.
As shown in fig. 1, the sensitive information monitoring system for a blockchain network of the present invention includes: a supervision system 200, and a blockchain network 101, a blockchain network 102 supervised by the supervision system. Moreover, the supervision system 200 implements supervision of sensitive information by interacting with nodes of each supervised blockchain network.
In the invention, the monitoring system 200 mainly provides online sensitive information analysis and identification service, and can realize sensitive information analysis and identification of transaction data generated in a blockchain network by configuring a sensitive information filtering library (comprising sensitive keywords, sensitive information characteristics and the like) and an identification algorithm (such as semantic identification, fuzzy matching and the like); for the means for realizing the sensitive information analysis and identification, the adjustment or the improvement can be carried out according to the content, the data form and the like of the transaction data of the chain under supervision, and the details are not repeated here.
Specifically, taking a block link point 1011 in the block link network 101 as an example, before performing a chain uplink operation on transaction data, the block link point 1011 sends a sensitive information detection request to the monitoring system 200, and determines whether to perform the chain uplink operation according to a detection result response of the monitoring system 200 to the transaction data; if the detection result response indicates that the transaction data contains sensitive information, canceling the uplink action; and after the uplink action is cancelled, reporting the transaction data to the supervision system 200 to record violation content.
As shown in fig. 2, the method for supervising sensitive information in a blockchain network according to the present invention is further illustrated by taking the full flow of supervised chain registration and sensitive information detection as an example based on the system architecture shown in fig. 1.
The supervised chain is accessed to the supervision system 200, and after registration and approval, the rear part can have the authority to interact with the supervision system 200. Namely, a manual application registration channel provides information such as a server public network IP address, a service request URL (domain name: port number or IP: port number), a public key of a block link point and the like.
After the registration approval is passed, the monitoring system 200 generates a corresponding app key and allocates the app key to the registered blockchain. Specifically, the monitoring system 200 performs access control in a manner of app + signature, and may also confirm an access entry of the monitored chain in a manner of setting an IP white list.
To ensure that the supervisory system 200 is able to fully supervise the chain of custody, a heartbeat mechanism is also established between the supervisory system 200 and the chain of custody. That is, the node of the block chain needs to periodically send a heartbeat detection request to the monitoring system 200, and receive a heartbeat detection result response of the monitoring system 200; if the heartbeat detection result responds to the indication node disconnection, the uplink operation is suspended. Therefore, sensitive information detection of some transaction data can be avoided from being missed due to disconnection of the block chain node and the monitoring system.
Before executing a business data uplink action, sending a sensitive information detection request to a monitoring system 200, and determining whether to execute the uplink action according to a detection result response of the monitoring system 200 to the business data; and if the detection result response indicates that the transaction data contains sensitive information, canceling the uplink. Specifically, the sensitive information detection request comprises an app key and a signature; wherein the Appkey is distributed by the supervisory system to the registered blockchain, the signature being generated based on a node private key of the blockchain network.
Maintenance updates, such as updates to the sensitive information filter base or optimization of the recognition algorithm, are performed from time to time in view of the sensitive information analysis and recognition services provided by the regulatory system 200. Therefore, the invention realizes the polling of all the block data on the monitored block chain by issuing the polling command through the monitoring system 200, and avoids certain sensitive information which cannot be identified before maintenance and update from being written into the block chain.
Specifically, the block link point 1011 receives the polling instruction issued by the monitoring system 200, and sends a polling request to the monitoring system 200 according to the polling instruction, so as to detect the sensitive information of each block data on the block chain. Meanwhile, the block link point 1011 receives a control instruction issued by the monitoring system 200, and masks or filters the block data containing the sensitive information on the block chain according to the control instruction. The management and control instruction issued by the monitoring system 200 is generated by the monitoring system according to the detection result of the sensitive information of each block data on the block chain. In practice, the block link point 1011 masks or filters the block data in the following manner: block data is prohibited from being queried or called.
Meanwhile, after the block link point 1011 masks or filters the corresponding block data, the illegal transaction content containing the sensitive information is also reported to the monitoring system 200. In order to avoid frequent polling requests of the supervision system, which causes the supervised blockchain network to consume a large amount of resources for responding to the polling instruction, a threshold value is set on a node of the supervised blockchain network, and only one active polling task is received at most within the threshold value time.
When the routing inspection task is executed on the node of the supervised block chain network, the quantity of block data needing sensitive information detection is configured through yml; if some block data detection fails in the polling task, timing processing is performed on the block data with the detection failure, and after all the block data of the block chain are processed, a message of the completion of the execution of the polling task is fed back to the monitoring system 200.
As shown in fig. 3, in another aspect of the present invention, there is also provided a block link point apparatus 1011 including:
the request module is used for sending a sensitive information detection request to the monitoring system before the uplink action of the transaction data is executed;
the acquisition module is used for acquiring the detection result response of the monitoring system to the transaction data;

Further, the sensitive information detection request sent by the request module comprises an Appkey and a signature; wherein the Appkey is distributed by the supervisory system to the registered blockchain, the signature being generated based on a node private key of the blockchain network.
In one embodiment, the request module is further configured to send a heartbeat detection request to a monitoring system; the acquisition module is used for acquiring the heartbeat detection result response of the monitoring system; the uplink action control module is used for controlling uplink actions according to the heartbeat detection result response of the monitoring system; and if the heartbeat detection result responds to the indication node disconnection, stopping executing the uplink action.
