FIG. 2 is a flowchart illustrating a method of generating information based on a blockchain, according to an exemplary embodiment.
As shown in fig. 2, in S202, the block link point receives first identity information of a first user.
In one embodiment, the first user may be, for example, a merchant user who may, for example, submit his first identity information in order to qualify itself for a higher degree of trust, as described above in the context. The first identity information may, for example, include information of the merchant may, for example, include: enterprise profile: such as nature of the enterprise, operating scope, time of establishment, registered funds, number of staff, location, floor space, etc. The first information may also include important information such as official seal of an enterprise. In the application, for safety, the enterprise information can also comprise key data for encrypting the enterprise information, for example, the enterprise can generate a private key by itself, and the public key, the enterprise information and certificates issued by other platforms or trusted qualification auditors can be used as first identity information.
In one embodiment, the first user may be, for example, an individual user, and the method of the present application is also applicable in situations where trusted confirmation of individual user information is required. For example, in a related industry such as finance, an individual user may, for example, use certificate information as the first identity information. The individual user submits the credential information for subsequent processing.
In one embodiment, the first user may be, for example, information of employee users in an enterprise, and the method of the present application is also applicable to a scenario in which trusted confirmation of employee user information is required. The staff user may, for example, use the relevant material such as the personal work certificate as the first identity information, and the staff user submits the relevant material such as the personal work certificate for subsequent processing.

In S204, second identity information of the first user is generated according to the first identity information encryption key and the encryption algorithm. The basic process of data encryption is to process the original file or data in plaintext according to a certain algorithm to form an unreadable code, usually called as ciphertext, so that the original content can be displayed only after the corresponding secret key is input, and the purpose of protecting the data from being stolen and read by illegal persons is achieved by the way. The reverse of this process is decryption, i.e., the process of converting the encoded information into its original data.
In one embodiment, the encryption algorithm comprises an encryption algorithm in a blockchain, which is a generic term of several technical solutions in nature, including peer-to-peer network transmission protocols, cryptographic encryption algorithms, distributed consensus mechanisms, and Nash balanced gaming designs. Based on the combination of the technologies, a reliable database with decentralization and trust removal can be realized, and an algorithm proving mechanism is used for guaranteeing traceable traceability, non-falsification and non-falsification of information recorded on a chain. The alliance blockchain refers to a blockchain of which the consensus process is controlled by a preselected node; for example, a community of 15 financial institutions, each running a node, and 10 institutions (2/3 confirmations) need to be obtained in order to validate each block. Blockchains may allow everyone to read or be limited to participants only, or walk a hybrid route, such as the root hash of the block and its API (application programming interface) to be exposed, which may allow the outside world to be used for a limited number of queries and to obtain blockchain state information. These blockchains may be considered "partially decentralised". The alliance chain adopts a multi-center mode, and the participant nodes are also preset and confirmed through a consensus mechanism. In the alliance chain, different from the public chain, authority setting and control can be performed, and the method has higher applicability and expandability. The encryption algorithm in the present application may be implemented, for example, by an encryption algorithm in a federated blockchain.

In one embodiment, the first user is an individual user who submits credential information for subsequent processing. And encrypting the first identity information through a preset encryption algorithm to generate second identity information of the user. When an individual user needs to prove his own credentials to other units or users, trusted authentication may be obtained in a particular platform, for example, by means of second identity information.
In one embodiment, the first user may be, for example, information about staff users in an enterprise, who may, for example, submit relevant material such as personal work certificates for subsequent processing. And encrypting the first identity information through a preset encryption algorithm to generate second identity information of the user. Where an employee user needs to prove his own work track to other units or corporate leaders, a trusted guarantee may be obtained, for example, through the second identity information.
In some embodiments, the first user may also be, for example, a user in other application scenarios, where the first user is not limited to being a person, and may also be, for example, some independent individuals, businesses, and public facilities, all objects for which trust authentication is required, as the first user in the present application. And encrypting the first identity information by a user in other application scenes through a preset encryption algorithm to generate second identity information of the user.
In S206, the first identity information is stored in a blockchain node.
In some embodiments, the first identity information and the second identity information are associated to obtain associated information; the second identity information is stored in a blockchain. After the first identity information is processed through blockchain related encryption, the generated second identity information can be associated with the first identity information through the blockchain.
In some embodiments, after the first identity information is associated with the second identity information, the second identity information is sent, for example, to a blockchain platform, or may be published, for example, to another qualification-capable platform.
According to the method for generating information based on the blockchain, disclosed by the application, the true identity of the user can be confirmed through a technical means, so that the user can quickly and accurately acquire the trusted authentication.

After the manual verification is passed, the e-commerce platform can issue certificates to enterprises.
In one embodiment, the enterprise has a certificate A issued by a trusted auditing organization, has a certificate B issued by a blockchain system, and the enterprise information comprises two certificates A and B, and can also comprise a private key signature S corresponding to the certificate A. The function of signature S is to prove the behaviour of the merchant in actively registering. (signature S may prevent merchants from becoming registered and merchant repudiation issues).
In S406, the enterprise information is stored into a block of a blockchain by a blockchain protocol, and signature information is generated. The e-commerce platform in the above step may, for example, store content such as certificates issued to businesses onto blockchains.
In one embodiment, storing the enterprise information into a block of a blockchain via a blockchain protocol and generating signature information includes: encrypting the enterprise information through a block chain protocol; and storing the enterprise information after encryption processing into the block.

In one embodiment, further comprising: acquiring signature information and update information of the commodity; determining a block in a block chain through the signature information; and storing the update information to the block by a blockchain process. When the enterprise information is changed, the block chain is applied for updating through the changed enterprise information. The updated enterprise information is linked to the updated enterprise information, and the updated enterprise information process can also be tracked and checked by a user in a blockchain mode.
In S408, commodity distribution information is generated from the commodity information and the signature information. Commodity release information is generated through commodity information and signature information, and can be released in the electronic commerce platform or other platforms with trusted cooperation with the electronic commerce platform. The user can obtain the data and signature information of the commodity by browsing the commodity information at the webpage end.
In one embodiment, a user may query enterprise information at the user's end through signature information. Multiple trusted e-commerce platforms or qualification verification platforms may also build trusted blockchain sites using respective certificates, for example. The user can consult from multiple parties to obtain the trusted and consistent information.
In one embodiment, further comprising: generating traceability information after the commodity is purchased; and sending the tracing information to a user terminal along with the commodity. For example, after the commodity is purchased, the traceability information is generated by commodity information, the signature information and purchaser information. The traceability information may be attached to the outer package of the minimum unit, or may be sent to the user along with an electronic bill or a paper bill of the commodity, or may be stored in a shopping record of the user, for example, but the application is not limited thereto.
In one embodiment, as in the enterprise information described above, there is a certificate a issued by a trusted audit authority, a certificate B issued by a blockchain system, and used in subsequent traceability, the user can find the merchant certificate a in the blockchain through the certificate B, and a signature S.
It should be clearly understood that the present application describes how to make and use specific examples, but the principles of the present application are not limited to any details of these examples. Rather, these principles can be applied to many other embodiments based on the teachings of the present disclosure.
According to the method for generating information based on the blockchain, when the blockchain system issues the certificate, the related information of the merchant can be extracted from various certificates uploaded by the merchant, so that the trouble that the merchant provides various information again is avoided, only the enterprise certificate A and the corresponding private key signature are provided during registration, and a large amount of labor cost is saved.
According to the method for generating information based on the blockchain, disclosed by the application, the true identity of the merchant can be confirmed through a technical means, so that the commodity sold by the merchant is more true and reliable, and the user experience is improved.
According to the method for generating information based on the blockchain, the registration process of merchants in the blockchain can avoid the problems of manual auditing business license, enterprise qualification and the like, and is suitable for business systems with less strict auditing requirements.
According to the blockchain-based information generation method, the blockchain system helps to verify the identity of the enterprise certificate holder, and after success, the blockchain self-applies for issuing the blockchain certificate of the manufacturer.
According to the method for generating information based on the blockchain, after a user buys goods, the user can look up the certificate of the merchant in the blockchain by checking the signature of the merchant, and then can trace back the real information of the merchant and the original certificate. The user verifies that the commodity is a user verification commodity signature and confirms the certificate B; the user verifies the merchant identity using certificate B, and the user can then find certificate a and signature S in the blockchain. Thereby confirming the merchant identity.
