Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
Fig. 1 shows a block chain supervision method based on cross-chain of the present invention, which is suitable for supervising chain nodes, and includes the following steps: s1: registration requests for a number of chains of custody are received. S2: the state of the connections between the chain of custody and the several chains of custody is verified. S3: and receiving report information sent by the managed chain before the block chain data is stored and uplinked. S4: and (4) checking the reported information to determine whether sensitive words are contained in the reported information. S5: and when the supervision chain detects that the reported information contains the sensitive words, the reported information is stored, and warning information is sent to the corresponding supervised chain. S6: and receiving a processing result of processing the block chain data sent by the chain under supervision. By the block chain supervision method based on the cross-chain, all supervised chains can be subjected to penetrating supervision by the unified supervision chain, supervision rules are unified, and supervision behaviors and results are stored. The above steps are specifically described below.
For step S1: registration requests for a number of chains of custody are received.
The public transparent executable characteristic of the intelligent contract is utilized to register and permit the authority of the supervised chain. Specifically, a plurality of chain of custody are registered through an intelligent contract running on the chain of custody, and the registration information of each chain of custody is stored in the chain of custody. And the authority of each chain to be monitored is set, so that each chain to be monitored can only check own information on the chain to be monitored, and the information safety is ensured. Wherein the registration information includes: company code, company name, blockchain name, access address, and port number. The company code is a social uniform identification code of the company. The blockchain name is the name of the blockchain of the current level registration. It will be appreciated that a company may operate several different services, corresponding to different block chains. Each blockchain is assigned a name that distinguishes the different blockchains under the same company name. The chain of custody can be connected into the chain of blocks registering the registration by accessing the address and port number.
Further, in the present invention, the chain of custody stores the company code as a key, and the company name, the blockchain name, the access address, and the port number as value-composed key-value pairs in the custody user database. The data structure of the company code as key is mapping data structure, and the data structure of the company name as value, the blockchain name, the access address and the port number is struct data structure. The data structure in the form of key value pairs can be used for quickly searching the registration information of a certain company under the condition of knowing the unique identifier, the behavior belongs to random reading, and the efficiency can be improved by using the data structure. value is used as an information field of an enterprise, a company is attached with specific attributes, and the struct data structure meets conditions in consideration of expansibility in the enterprise.
For step S2: the state of the connections between the chain of custody and the several chains of custody is verified.
After the chain under supervision is registered by the registration in step S1, the chain under supervision accesses the chain under supervision through the registered access address and port number. And the monitoring chain sends heartbeat detection signals to the monitored chain at regular time to judge whether the monitored chain is normally connected or not. And if the connection is abnormal, informing the monitored chain to perform manual intervention processing. And under the condition of normal connection, the supervision chain judges the activity degree of the supervised chain according to the returned data of the supervised chain on the heartbeat detection. The data returned by the heartbeat detection comprises block information and transaction summary information.
For step S3: and receiving report information sent by the managed chain before the block chain data is stored and uplinked.
During the operation of the chain under supervision, when a transaction occurs in the blockchain, the chain under supervision needs to store and chain up blockchain data corresponding to the transaction. And sending the report information to the supervision chain before the supervised chain stores and uplinks the block chain data. The reported information comprises the unique identification of the block chain data and the transaction content. The unique identifier is a number corresponding to the blockchain data and is a unique identification code of the blockchain data. The transaction content is the content needing to be linked up at this time.
For step S4: and checking the reported information to confirm whether the reported information contains sensitive words.
Specifically, a sensitive word bank is stored in the supervision chain, the reported information and the keywords in the sensitive word bank are automatically compared and matched, and whether the block chain data of the transaction contains sensitive words or not is identified. And when the sensitive word is not matched, the supervision chain returns confirmation information to the corresponding supervised chain, and the supervised chain carries out uplink on the block chain data.
For step S5: and when the supervision chain detects that the reported information contains the sensitive words, the reported information is stored, and warning information is sent to the corresponding supervised chain.
When the matching result of step S4 shows that the reported information contains a sensitive word, the chain of custody first stores the reported information and sends the warning information to the corresponding chain of custody. Wherein the alert information includes a risk level. The risk level depends on the level of matching to sensitive words. Specifically, when the supervision chain detects that the reported information contains the sensitive word, the chain linking and the certificate storing are carried out on the reported information to generate a hash, and the generated hash can be used for tracing the detection behavior of the sensitive word of the supervised chain.
For step S6: and receiving a processing result of processing the block chain data sent by the chain under supervision.
The supervised chain receiving the warning information processes the block chain data trying to store the uplink at this time and sends the processing result to the supervisory chain, the supervisory chain can be right the supervised chain processing result is reported to carry out the uplink storage and generates a hash, and the generated hash can be used for tracing the detection behavior of the sensitive words of the supervised chain, so that the supervised chain is prevented from being repudiated.
Specifically, the supervised chain analyzes the blockchain data of the current attempted storage uplink to determine whether to continue to store the uplink. When the uplink is selected to be abandoned, the uplink storing operation on the block chain data is cancelled, and first processing result information of the abandoned uplink is sent to the supervision chain, wherein the first processing result information comprises the unique identifier and the abandoned uplink mark. And when the continuous uplink is selected, performing uplink storage operation on the block chain data, and sending second processing result information of the continuous uplink to the supervision chain, wherein the second processing result information comprises a unique identifier, a continuous uplink mark and transaction detailed information, and the transaction detailed information is added with detailed transaction content on the basis of the transaction information. The transaction detail information includes transaction information, a transaction initiator account, a transaction receiver account, a transaction type, a transaction production time and the like.
For the transaction with the risk of the sensitive word, the operator of the chain under supervision first judges whether canceling the transaction has a large influence on the current service, if the influence is not large, the operator can choose to terminate the transaction, and the corresponding block chain data cannot be linked up. In this case, the chain of custody sends the first processing result information to the chain of custody. It will be appreciated that in some cases, terminating a current transaction may have a significant impact on the traffic of the chain of custody. And in order to not influence the normal operation of the service, the monitored chain party selects to continue the transaction, stores the block chain data uplink in the block chain, and sends second processing result information to the monitoring chain.
Preferably, the supervisor chain receives the second processing result information of the continuous uplink sent by the supervised chain, stores the second processing result information, and sends a supervision instruction to the supervised chain to perform shielding processing on the sensitive words in the block chain data of the uplink. Since the blockchain is a decentralized service application, it is necessary to say that a management instruction is commonly recognized to each node on the supervised chain to achieve decentralized management, and therefore, a basic intelligent contract is adopted here, that is, a management intelligent contract is generated when the blockchain system is started.
Further, the chain of custody checks the result of the masking processing after sending the command of custody. The verification method can be set according to actual needs. In this embodiment, the check is performed by accessing the sensitive word that arrives at the policing instruction next on the chain of custody. If the shielding is successful, the verification is passed, and if the shielding is not successful, the verification is not passed, and manual intervention is carried out.
It will be appreciated that sensitive information may exist in the content that the chain of custody has previously been linked up when the thesaurus in the chain of custody for storing sensitive words is updated. Therefore, when the word bank for storing the sensitive words in the supervision chain is updated, the supervision chain sends the patrol inspection instruction to the plurality of supervised chains, and each supervised chain receives the patrol inspection instruction and then performs scanning detection on all the data which are linked up again to identify the sensitive words in the linked-up data. And after the scanning detection is finished, the monitored chain sends the scanning detection result back to the monitoring chain. And if the sensitive information is found after rescanning detection, shielding the detected sensitive information.
