Example one

Referring to fig. 1, an embodiment of the present invention provides a system for authentication, storage and instant query based on blockchain data, which includes a blockchain system 10 and a plurality of service systems 20; the block chain system establishes communication connection with a plurality of service systems through communication interfaces or communication protocols; the business system is deployed into each core enterprise;

the block chain system 10 is configured to receive a request issued by a core enterprise certificate, obtain enterprise information of a core enterprise, construct a uuid belonging to a current core enterprise based on the enterprise information of the core enterprise, and issue the uuid to a service system

The business system 20 is configured to perform hash algorithm encryption on the asset data and the business data belonging to the core enterprise to obtain encrypted target data; the business system is also used for storing the non-secret data and the target data which belong to the core enterprise as a whole into a database as packed data, and mapping the storage position of the database where the encrypted target data and the non-secret data (namely the packed data which does not need to be encrypted) are located to the uuid identifier in the corresponding enterprise information module of the core enterprise in the block chain system to realize data binding; the business system is also used for requesting a security token from the blockchain system, and after the security token is obtained, the business system adds the security token into a data head (head) of the packed data;

the block chain system 10 is further configured to receive the packed data sent by the service system after verifying that the security token is correct, and perform chain storage operation on the packed data; the hashcode returned by the uplink is stored in the service system.

In a specific technical scheme of the application, each core enterprise is internally connected with a plurality of sub-enterprise modules; the sub-enterprise module is used for firstly changing the asset data and the business data of the core enterprise, then sending the changed asset data and the changed business data to the business system of the core enterprise, and carrying out first audit verification on the business system of the core enterprise. After the core enterprise verifies and checks, the chain linking operation can be carried out; in the subsequent uplink operation process, the secondary verification such as encryption of the packed data of the core enterprise and application of the security token is further required, and the final uplink storage operation of the packed data can be performed only after the secondary verification is qualified.

In the specific technical scheme of the application, since the chain data of the block chain is traceable and not falsifiable, a very important problem in the existing application is how to guarantee the authenticity and credibility of the source data, that is, how to guarantee that the uplink data of an enterprise is based on the authentic trade background, rather than being forged or falsified.

The system comprises a business system and a block chain system, wherein the business system stores assets or business data, and the block chain system is the chain mapping of the business system. Considering that the prior blockchain system is not suitable for storing larger files, blockchain storage data is designed, different services are packaged into functional modules, the modules interact through interfaces and communicate with the outside, and the transaction modules select necessary key data according to the requirements of service and privacy protection, encrypt the data by adopting different encryption modes (mainly a Hash algorithm in the scheme), correspond to the unique code of an enterprise in the system and record the encrypted data on a blockchain.

Example two

Referring to fig. 2, correspondingly, a second embodiment of the present invention provides a method for authenticating, storing and instant querying based on block chain data, including performing the following push operation by using the system for authenticating, storing and instant querying based on block chain data:

step S100, a block chain system receives a request issued by a core enterprise certificate, acquires enterprise information of a core enterprise, constructs a uuid belonging to the current core enterprise based on the enterprise information of the core enterprise and issues the uuid to a service system; the only uuid distributed to the core enterprise by the business system is the uuid identifier; the uuid is also a public key of the core enterprise in the current business system;

s200, the business system carries out Hash algorithm encryption on the asset data and the business data belonging to the core enterprise to obtain encrypted target data; the business system also stores the non-secret data and the target data which belong to the core enterprise as packed data into a database, and then maps the storage position of the encrypted target data and the non-secret data (namely the packed data which do not need to be encrypted) in the database to the uuid in the corresponding enterprise information module of the core enterprise in the block chain system to realize data binding;

step S300, the business system requests a security token from the blockchain system, and after obtaining the security token, the business system adds the security token into a data header (head) of the packed data; after the block chain system verifies that the security token is correct, the block chain system receives the packed data sent by the service system and executes chain storage operation on the packed data;

in step S400, the hash code returned from the uplink in the block chain system is stored in the service system.

In the execution process of the step S100, the blockchain system receives a request for establishing a core enterprise credential, obtains enterprise information of a core enterprise, and constructs a uuid belonging to the current core enterprise based on the enterprise information of the core enterprise; the unique uuid distributed to the core enterprise by the service system is a uuid identifier; the uuid is also a public key of the core enterprise in the current business system;

it should be noted that, the above technical solution relates to the following initialization operation, that is, a request issued by a core enterprise certificate is received, enterprise information of a core enterprise is obtained, if the core enterprise is not registered, registration is required and data update is completed, the enterprise information is packaged as a main module, a unique uuid allocated to the core enterprise by the business system in the system is an identifier, and the uuid is also a public key of the core enterprise in the system. Core enterprise key = (uuid, core enterprise private key uuid _ sk); obviously, during operation, only the core enterprise can enjoy the authority of applying the uuid identifier, the subsidiary enterprises which are attached to the core enterprise do not have the authority, if the subsidiary enterprises want to change the uplink packed data, the subsidiary enterprises need to apply to the internal core enterprise, and uplink operation can be performed after the core enterprise verifies and audits the uplink packed data; in the subsequent uplink operation process, secondary verification such as encryption and security token application on the packaged data of the core enterprise is further required, and the final packaged data uplink certificate storage operation can be performed after the secondary verification is qualified.

During the execution of step S200, there may be a plurality of methods for packaging asset data and service data: under the condition that a core enterprise wants to keep business data and asset data secret, the business data and the asset data can be encrypted through a Hash algorithm and then mapped onto the data of the enterprise information module: data = (uuid, hash (asset/traffic)); if there is no special encryption requirement, the storage position of the service and asset data in the database can be directly mapped to the uuid: data = (uuid, database location (asset/business Data)).

Referring to fig. 3, in the process of executing step S300, the service system requests a security token from the blockchain system, and after obtaining the security token, the service system adds the security token into a header (head) of the packed data, specifically including:

step S310, a core enterprise sends a uplink request to a block chain system through a service system; the uplink request is also a security token application request;

step S320, the core enterprise signs the security token application request by using the private key to obtain signature information;

step S330, the uuid identification and the signature information of the core enterprise are sent to a block chain system for application; when the blockchain system judges that the uuid identification and the signature information of the current core enterprise are in a preset mapping relation, the blockchain system verifies and confirms that the current verification information is real information, and returns an issuing safety token to a service system of the current core enterprise;

step S340, after the business system where the core enterprise is located obtains the security token, the business system adds the security token into a data header (head) of the packed data.

Referring to fig. 4, in the process of executing step S300, the hash code returned by the uplink in the blockchain system is stored in the service system, which specifically includes:

step S410, the block chain system determines the running device of the current uplink certificate, and stores the hash code returned to the service system where the core enterprise is located in the service system after all the packaged data of the current core enterprise completes the uplink certificate.

Referring to fig. 5, after the hash code returned by the chain on the blockchain system is stored in the service system, the method further includes a process of the core enterprise starting to query the blockchain certificate. The core enterprise starts a processing process of inquiring the block chain certificate storage, and the processing process comprises the following steps:

step S510, after a business system where a core enterprise is located finishes block chain chaining, generating a two-dimensional code link through a hash code returned by the block chain chaining;

step S520, compressing the two-dimension code link into a short link, and converting the short link into a two-dimension code picture again;

and S530, attaching the converted two-dimension code picture to a two-dimension code picture corresponding storage module reserved by the digital certificate.

Referring to fig. 6, before step S200, the method further includes modifying the asset data and the business data of the core enterprise:

step S110, a business system where a core enterprise is located is provided with a plurality of sub-enterprise modules;

step S120, the sub-enterprise module firstly changes the asset data and the service data of the core enterprise, and then sends the changed asset data and the changed service data to a service system of the core enterprise;

and step S130, after the business system where the core enterprise is located passes the audit, executing step S200.

The system and the method for authenticating, storing and instantly inquiring data based on the block chain ensure the authenticity of uplink data to the maximum extent, thereby constituting linkage response of a core enterprise and supply chains of all small enterprises and ensuring the completeness and maturity of the supply chains. .
