Detailed Description
The invention is described in detail below with reference to the drawings and the specific embodiments.
As shown in fig. 1, the block chain supervision method based on cross-chain of the present invention is suitable for a supervision chain node, and comprises the following steps: s1: a registration request is received for a number of chains under supervision. S2: the connection state between the chain of custody and the number of the chain of custody is verified. S3: and receiving report information sent by the chain of custody before storing and uploading the blockchain data. S4: and checking the reported information to determine whether the reported information contains sensitive words. S5: and when the chain of custody detects that the report information contains the sensitive word, the report information is stored, and warning information is sent to the corresponding chain of custody. S6: and receiving a processing result which is sent by the chain of custody and is used for processing the blockchain data. Through the block chain supervision method based on the cross chain, the unified supervision chain can carry out penetration supervision on all the supervised chains, unified supervision rules and store supervision behaviors and results. The above steps are specifically described below.
For step S1: a registration request is received for a number of chains under supervision.
Registration and permission admission are performed on the chain of custody by using the public transparent executable characteristics of the intelligent contract. Specifically, several chains under supervision are registered by means of an intelligent contract running on the chain under supervision, and registration information of each chain under supervision is stored in the chain under supervision. And the authority of each chain under supervision is set, so that each chain under supervision can only check own information on the chain under supervision, and the information security is ensured. Wherein the registration information includes: company code, company name, blockchain name, access address, and port number. The company code is a social unified identification code of the company. The blockchain name is the name of the blockchain registered at the current level. It will be appreciated that a company may operate several different services, which correspond to different blockchains. Each blockchain is assigned a name that distinguishes between different blockchains under the same corporate name. The chain of custody may be connected into the blockchain of registration by access addresses and port numbers.
Further, in the present invention, the chain of custody stores company codes as keys and company names, blockchain names, access addresses, and port numbers as value constituent key pairs in the monitoring user database. The data structure of the company code as the key is a mapping data structure, and the data structure of the company name, the blockchain name, the access address and the port number as the value is a struct data structure. The data structure in the form of key value pairs can quickly find out the registration information of a certain company under the condition of knowing the unique identification, and the behavior belongs to random reading, so that the efficiency can be improved by using the data structure. value is taken as an information field of a company, the company is attached with a specific attribute, and the expansibility of the company is considered, so that the struct data structure meets the condition.
For step S2: the connection state between the chain of custody and the number of the chain of custody is verified.
After registering the chain of custody through step S1, the chain of custody accesses the chain of custody through the registered access address and port number. And the chain of custody sends heartbeat detection signal to the chain of custody at regular time and judges whether to connect with the chain of custody normally. And if the connection is abnormal, notifying the chain to be regulated to perform manual intervention treatment. Under the condition of normal connection, the chain of custody judges the activity degree of the chain of custody according to the return data of the chain of custody to 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 chain of custody before storing and uploading the blockchain data.
The chain of custody needs to store and uplink the blockchain data corresponding to the transaction when the transaction occurs in the blockchain during operation. Before the chain of custody stores and uploads the blockchain data, reporting information is sent to the chain of custody. Wherein the reported information includes a unique identification of blockchain data and transaction content. The unique identifier is the number corresponding to the blockchain data and is the unique identification code of the blockchain data. The transaction content is the content which needs to be uplink at this time.
For step S4: and checking the reported information to determine whether the reported information contains sensitive words.
Specifically, the chain of custody stores a sensitive word stock, automatically compares and matches the reported information with keywords in the sensitive word stock, and identifies whether the blockchain data of the transaction contains the sensitive word. When the sensitive word is not matched, the chain of custody returns confirmation information to the corresponding chain of custody, and the chain of custody uplinks the blockchain data.
For step S5: and when the chain of custody detects that the report information contains the sensitive word, the report information is stored, and warning information is sent to the corresponding chain of custody.
When the matching result in the step S4 shows that the report information includes a sensitive word, the chain of custody first stores the report information and sends the warning information to the corresponding chain of custody. Wherein, the warning information contains a risk level. The risk level is dependent on the level of matching to the sensitive word. Specifically, when the chain of custody detects that the report information contains the sensitive word, the chain of custody is carried out on the report information to generate a hash, and the generated hash can be used for tracing the detection behavior of the sensitive word of the chain of custody.
For step S6: and receiving a processing result which is sent by the chain of custody and is used for processing the blockchain data.
The chain under supervision who receives warning information processes the chain of block data who tries to store the chain of block this time and sends the processing result to the chain of supervision, chain of supervision can report to be processed the result of chain of supervision and report and go on chain of supervision and deposit the certificate and generate the hash, and the hash of formation can be used to the traceability of chain of supervision sensitive word detection action, prevents chain of supervision repudiation.
Specifically, the chain under supervision analyzes the blockchain data that is attempting to store the uplink this time to determine whether to continue storing the uplink. When the discard of the uplink is selected, the storage of the uplink operation on the blockchain data is canceled, and first processing result information of the discard of the uplink is sent to the chain of custody, wherein the first processing result information comprises a unique identification and a discard uplink mark. And when the continuous uplink is selected, storing the blockchain data, and sending second processing result information of the continuous uplink to the chain of custody, 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 detailed information includes transaction information, a transaction initiator account, a transaction receiver account, a transaction type, a time of transaction production, and the like.
For transactions with sensitive word risks, the operator of the chain of custody first judges whether canceling the transaction brings great influence to the current service, if the influence is not great, the transaction can be selectively terminated, and the corresponding blockchain data cannot be uplink. In this case, the chain of custody transmits 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 chain of custody business. And the party of the chain of custody chooses to continue the transaction in order not to influence the normal operation of the service, saves the block chain data uplink in the block chain, and sends second processing result information to the chain of custody.
Preferably, after receiving the second processing result information of the continuous uplink sent by the chain under supervision, the supervision link stores the second processing result information and sends a supervision instruction to the chain under supervision to mask the sensitive words in the block chain data of the uplink. Because the blockchain is an decentralized service application, the management and control instruction needs to be commonly recognized to each node on the monitored chain in order to realize the decentralized management and control, and therefore, the basic intelligent contract is adopted, namely, the management and control intelligent contract is generated when the blockchain system is started.
Further, the chain of custody also verifies the masking results after sending the management and control instructions. The verification method can be set according to actual needs. In this embodiment, verification is performed by accessing a sensitive word on the chain of custody that issues a management instruction. If the shielding is successful, the verification is passed, and if the shielding is unsuccessful, the verification is not passed, and the manual intervention is performed.
It will be appreciated that when a thesaurus update in the chain of custody is used to store sensitive words, sensitive information may exist for content that the chain of custody has originally been trained on. Therefore, each time the word stock for storing the sensitive words in the chain of supervision is updated, the chain of supervision sends a patrol instruction to a plurality of chains of supervision, and each chain of supervision carries out rescanning detection on all data which are already in the chain after receiving the patrol instruction, and the sensitive words in the chain of supervision data are identified. After the scanning detection is completed, the chain of supervision sends the scanning detection result back to the chain of supervision. And if the existence of the sensitive information is found after rescanning and detection, shielding the detected sensitive information.
