All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the present invention provides a technical solution: a data isolation transmission method of a data homonymous channel based on a block chain is characterized in that: the method comprises the following steps:
s1: a service person of a commission office operates on the block chain management platform according to a specific service instruction, applies for a block chain certificate and then fills in block chain certificate information;
s2: on the basis of the step S1, after receiving the block chain certificate application request and verifying that the certificate information is correct, the block chain network administrator may generate a block chain certificate and send the block chain certificate to the commission office operator through the block chain network, and after receiving the block chain certificate application request and verifying that the certificate information is correct, the block chain network administrator generates a block chain certificate and sends the block chain certificate to the commission office operator through the block chain network, so that the certificate identifier may be fragmented in the form of channels to clarify the data right of each channel, thereby implementing privacy protection of data on the chain and providing greater security in use;
s3: based on step S2, the blockchain network administrator may create a data channel with the same name by using the identifier of the blockchain certificate as the name of the data channel according to the blockchain certificate, and segment the data in the form of channel by using the identifier of the blockchain certificate as the name of the data channel, so as to clarify the data ownership of each channel, thereby implementing privacy protection of the data on the chain and ensuring higher security during use;
s4: based on step S3, the commission office attendant can invite other block-tied nodes to join the co-named data channel.
The block chain network comprises a plurality of channels with the same name, and the channels with the same name are all set with the same name according to the specific business name.
And the data flows in the channels with the same name are all proprietary data of specific services.
The access isolation is arranged on the homonymous channel, the access rejection limit is set for the block chain link point which is added into the homonymous channel, the access isolation is set on the homonymous channel, the access rejection limit can be set for the block chain link point which is added into the homonymous channel, the data logic storage isolation is realized, the privacy protection of data is realized, the access rejection limit is set for the block chain link point which is added into the homonymous channel, the data physical storage isolation is realized, and the stability of the data storage of the block chain system is improved.

Examples
1. Related department clerks apply for a chain winding certificate on the block chain management platform, and set a chain winding certificate identifier, for example, the chain winding certificate identifier of related department household is GongAnJu-HuJiKe, the identifier format is a department full spelling + a business full spelling, the identifier is divided by a middle marking line, the identifier is used as a mark of the certificate, and the mark is used as a channel name in the following process, and the uniqueness of the mark on the block chain is ensured by using the department full spelling + the business full spelling;
2. an administrator reviews the certificate application and generates a block chain certificate, wherein the block chain certificate is a certificate in a block chain system, and the uplink certificate is a block chain certificate used in uplink, which is not different in nature and is called less identically only in different application scenarios;
3. after the block chain certificate is generated, the administrator is responsible for taking the chain certificate as an identifier to create a channel with the same name;
4. the channel is a very important concept in a block chain system, is a private atomic broadcast channel which is divided and managed by a sequencing node, and aims to isolate the information of the channel, so that an entity outside the channel cannot access the information in the channel, and the privacy of transaction is realized; the current channel is divided into a system channel and an application channel, the sequencing node manages the application channel through the system channel, the transaction information of a user is transmitted through the application channel, and for a general user, the channel refers to the application channel; the channels are managed by the ordering service node, which is also responsible for ordering transactions in the channels. The block chain nodes establish and join the channel by sending transaction, and only after the channel is added, the data of the channel can be synchronized in the block chain nodes, so that the storage isolation of the data is realized, the logical storage isolation of the data is realized for different channels added by the same block chain node, and the physical storage isolation of the data is realized for different block chain nodes in the same block chain network because the different block chain nodes do not belong to different channels;
5. the related department clerks invite other block chain link points to join the channels with the same name of the uplink certificate identification so as to share data;
6. distributing uplink certificates for the data sources of the household registration departments by office workers of related departments;
7. when data are uplinked, the data are uploaded to a channel with the channel name of GongAnJu-HuJiKe by using a certificate marked by GongAnJu-HuJiKe; only nodes which are added with GongAnJu-HuJiKe channels have data of household registration departments of related departments, on the same server, data with different channel names exist in different data directories to realize soft isolation of the data, on different servers, as long as the servers are not added with the GongAnJu-HuJiKe channels, the servers do not have the data of the household registration departments of the related departments to realize soft isolation of the data, and the certificate identification names are taken as the channels to realize privacy protection of sensitive data.
The above-mentioned embodiments, objects, technical solutions and advantages of the present invention are further described in detail, it should be understood that the above-mentioned embodiments are only illustrative of the present invention and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
