A proxy node is a concept used in blockchain networks. These networks typically employ a delegated rights-proving consensus mechanism that can be delegated to specific nodes that are responsible for validating transactions and generating new blocks.
Fig. 1 to fig. 3 are respectively a flowchart of a blockchain-based industrial internet identification information analysis method according to an embodiment of the present invention, a process of obtaining identification information analysis plaintext by a client in the blockchain-based industrial internet identification information analysis method according to the present invention, and a structural schematic diagram of a blockchain network in the blockchain-based industrial internet identification information analysis system according to the present invention.
The embodiment of the invention provides an industrial Internet identification information analysis method based on a blockchain, which comprises the following steps:
acquiring scanning information received by a scanning end, and generating a first information analysis request based on the scanned mark information and the identity information of the scanning end;
responding to the first information analysis request, and selecting one of a plurality of proxy nodes deployed in a blockchain as an analysis proxy node;
the analysis agent node performs segmentation recombination on the codes of the mark information in the first information analysis request according to a pre-stored segmentation dispatching rule to generate a second information analysis request, and converts the extracted data in a first characteristic section in the first information analysis request and a second characteristic section in the second information analysis request into first characteristic data and second characteristic data respectively, wherein the number of characters contained in the first characteristic section is equal to the number of characters contained in the second characteristic section, and the positions of the characters in the corresponding information analysis request are the same;
the analysis proxy node sends the first characteristic data to a first encryption node, and sends a first analysis request and a second analysis request to a second encryption node, wherein the first analysis request comprises the first information analysis request and the first characteristic data, and the second analysis request comprises the second information analysis request and the second characteristic data;
the second encryption node analyzes the first analysis request and the second analysis request into a first analysis plaintext and a second analysis plaintext respectively, and sends the first analysis plaintext and the second analysis plaintext to the first encryption node;
the first encryption node determines the attribute of the first analytic plaintext and the second analytic plaintext according to the first characteristic data and the first analytic plaintext and the second analytic plaintext;
and responding to the information analysis key input by the client, and determining whether the first analysis plaintext or the second analysis plaintext is to be sent to the client by the first encryption node according to the information analysis key and the attribute.
Referring to fig. 3, the parsing proxy node, the first encryption node, and the second encryption node are all selected from a plurality of proxy nodes deployed in a blockchain, and all belong to the same class of proxy nodes. The second encryption node comprises a plurality of analysis nodes, each analysis node has different analysis keys, and only the analysis request of the corresponding segment can be analyzed, but analysis results of other analysis nodes are recorded in the analysis node.
With continued reference to fig. 1 and 2, a method for selecting a resolution proxy node from a plurality of proxy nodes deployed in a blockchain includes:
and calculating a corresponding analysis grade according to the mark information and the identity information of the scanning end, and determining a corresponding proxy node type according to the analysis grade so as to select an analysis proxy node.
It can be understood that the detail degree of the analysis content obtained according to the identity information of the scanning end is different, for example, the analysis plaintext obtained by scanning the commodity identification on the scanning machine inside the manufacturer contains all commodity information, such as the production date, the production place, which production line, the raw material proportion, etc.; the resolved plaintext information obtained by the code scanning of the consumer only comprises the production date and the production place;
therefore, the resolution level of the scanning end in the manufacturer is higher than that of the scanning end used by the supplier/retailer, the proxy nodes with different levels are respectively selected as the resolution proxy nodes and correspondingly obtained resolution plain texts with different levels, for example, the scanning end in the manufacturer adopts the high-level proxy node as the resolution proxy node, the scanning end used by the supplier/retailer adopts the medium-level proxy node as the resolution proxy node, and the scanning end of the consumer adopts the low-level proxy node as the resolution proxy node.
Specifically, the pre-stored segment dispatch rules include:
dividing a first information analysis request into at least two split sections according to the mark information, and determining a generation method of the second information analysis request according to whether character strings with the same length exist between the split sections;
if at least two split segments have the same length character string, the positions of the split segments with the same length character string are exchanged to form the second information analysis request;
if character strings with the same length do not exist between any two split sections, selecting one split section of the first information analysis request to replace the content of the first information analysis request with a random character string with the corresponding same length;
wherein, the random character string is different from the content of the split segment corresponding to the exchange, and the content of the character strings corresponding to the two split segments with the same length of character string is different.
It can be appreciated that, for example, the first information resolution request is 105687023697102:
if the information is split into 105687023697102 according to the corresponding flag information, wherein the character lengths in the two split segments 10 and 70 and the two split segments 568 and 236 are the same, at least one group of the two split segments can be selected to be exchanged to obtain a second information analysis request, and the second information analysis request can be one of 70 568 10 23697102, 10 236 70 568 97102 or 70236 10568 9710 2;
if the character string is split into 105687023697102 according to the corresponding mark information, and there is no split segment with equal character strings, at least one split segment of the five split segments is randomly selected to be replaced by a random character string with the same length, such as 1 23 687023697102, 105687 0246 97102, etc.
With continued reference to fig. 1, when the first feature data and the second feature data are converted, converting the data in the first feature segment in the extracted first information analysis request into the first feature data according to a pre-stored data conversion rule, and converting the data in the second feature segment in the second information analysis request into the second feature data;
the data conversion rule comprises a first conversion rule and a second conversion rule, and the conversion method of the conversion rule comprises the following steps:
converting the characteristic segment into characteristic data by using the first conversion rule, and judging whether to use the second conversion rule according to the characteristic data conversion result converted by the first conversion rule;
if the converted first characteristic data and the second characteristic data are the same, judging that the characteristic segment is converted into the characteristic data by using the second conversion rule;
if the converted first characteristic data and the second characteristic data are different, judging that the second conversion rule is not used;
the conversion results of the first conversion rule and the second conversion rule on the same characteristic section are different.
Specifically, the first conversion rule is to sequentially sort the characters in the characteristic section according to the English initial letters of the characters, and the second conversion rule is to convert the character strings in the characteristic section into a binary writing method.
It will be understood that, if the first information analysis request is 012, the second information analysis request is 013, the selected first feature segment is 012, the second feature segment is 013, and the 012 and 013 are converted into zot and zot according to the first conversion rule by capitalizing English letters corresponding to each number, and then the first feature data zot and the second feature data zot are identical, the data conversion needs to be performed again by using the second conversion rule, that is, 012 and 013 are converted into 1100 and 1101 according to the binary method, and 1100 is set as the first feature data, and 1101 is set as the second feature data.
Specifically, the method for the second encryption node to parse the first parsing request and the second parsing request into the first parsing plaintext and the second parsing plaintext respectively includes:
the second encryption node segments the information analysis request based on the mark information, distributes the first analysis request and the second analysis request to a plurality of corresponding analysis nodes according to the number of segments, and distributes a segmented analysis key to each analysis node correspondingly;
and each analysis node analyzes the first analysis plaintext and the second analysis plaintext based on the segmentation analysis key, the first analysis request and the second analysis request respectively to form a corresponding first analysis plaintext and a corresponding second analysis plaintext, and sends the corresponding first analysis plaintext and the corresponding second analysis plaintext to the first encryption node.
It may be appreciated that, for example, the first information resolution request is segmented into 105687023697102, the second information resolution request is segmented into 10 236 70 568 97102, and the segments are divided into five segments, and then the segments are sent to the corresponding five resolution nodes respectively:
the first analysis node analyzes a first section of a first information analysis request and a first section of a second information analysis request, wherein the first section analysis result of the first information analysis request is recorded in a first analysis plaintext file of the other four analysis nodes, and the first section analysis result of the second information analysis request is recorded in a second analysis plaintext file of the other four analysis nodes;
the second analysis node analyzes a second section of the first information analysis request and a second section of the second information analysis request, wherein the second section analysis result of the first information analysis request is recorded in a first analysis plaintext file of the other four analysis nodes, and the second section analysis result of the second information analysis request is recorded in a second analysis plaintext file of the other four analysis nodes;
the processing mode of other analysis nodes is the same as the first analysis node and the second analysis node.
Specifically, the industrial Internet identification information analysis method based on the blockchain further comprises the following steps:
the first encryption node scans the contents of the first analytic plaintext and the second analytic plaintext respectively, and determines the attributes of the first analytic plaintext and the second analytic plaintext according to whether the first characteristic data are present at the corresponding positions of the analytic plaintext.
It can be appreciated that the previously obtained feature data may be a suffix, a header, or other place that corresponds to the parsed plaintext that may not affect the integrity of the parsed plaintext; if the first feature data 1100 is used as the suffix of the first feature plaintext, i.e. added behind the parsed information, 1100, or the first feature data 1100 is used as the title of the first feature plaintext, i.e. added with a title with the content of 1100 in the parsed information file; the second feature data is located at the same position as the first feature data.
Specifically, the contents of the first characteristic section and the second characteristic section are different, and if the contents of the selected first characteristic section and the selected second characteristic section are the same, the selection is performed again.
It will be appreciated that, for example, the first information resolution request segment is 105687023697102, the second information resolution request segment is 10 236 70 568 97102, and the first feature segment and the second feature segment are 9710, and the first feature segment and the second feature segment need to be re-selected to be different in content.
Specifically, the first encryption node selects to send an analysis plaintext of the corresponding attribute to the client according to the attribute of the information analysis key;
and the client determines the modification authority of the resolving plaintext according to the authority of the information resolving key and records the modification authority in an information log.
It can be understood that the second encryption node sends the first parsed plaintext and the second parsed plaintext to the first encryption node, the first encryption node selects the parsed plaintext having the same feature data to determine the parsed plaintext as the correct attribute, determines the other parsed plaintext as the error attribute, sends the parsed plaintext of the correct attribute to the client if the client inputs the correct parsed key during scanning, and sends the parsed plaintext of the error attribute to the client if the wrong parsed key is input.
In the implementation, the resolving plaintext of the correct attribute and the resolving plaintext of the error attribute can be correspondingly modified and the content in the authority range of the scanning end is saved, the modification record and the checking record are respectively recorded in the log, and if checking and modifying the resolving plaintext of the error attribute exist, the previous modification log is automatically popped up when the resolving plaintext of the correct attribute is checked next time.
Fig. 4 is a schematic structural diagram of an industrial internet identification information analysis system based on blockchain according to an embodiment of the invention.

the analysis request sending end is connected with the scanning end and used for sending an analysis request to the blockchain network;
