Description
Technical Field
The invention belongs to the field of block chains and digital currency, and particularly relates to an identity authentication method based on non-homogeneous certificates, network equipment and terminal storage equipment.
Background
Identity authentication is also called verification and authentication, and means that the identity of a user is confirmed by a certain means. There are many methods for identity authentication, which can be basically divided into three categories: shared key based authentication, biometric based authentication, and public key encryption algorithm based authentication. The security of different identity authentication methods is high and low respectively, and the identity information of the user is controlled by a third party, the identity owner is not owned by the user, the transaction cannot be conducted freely, and the risk of tampering exists.
Non-homogeneous Token (NFT) is a digital property ownership based on block chains that has properties of being inseparable, irreplaceable, unique, verifiable, negotiable, tradable, and tradable. NFT is a concept corresponding to a homogeneous token (FT), also referred to as a non-homogeneous token, a heterogeneous token, a non-exchangeable token, a non-interchangeable token, and the like.
In the traditional identity authentication system, the identity information of the user, especially the right information, is managed by a third-party organization, is stored in a centralized server, is easy to be leaked and attacked, and the user cannot completely master the identity right information. In addition, the user often needs to manage different identity rights in different digital scenes, which brings inconvenience to the user, and privacy information is easily leaked in the authorization process, thereby causing the use of false information.
Disclosure of Invention
Aiming at the problems that the traditional identity authentication management is centralized and the identity rights and interests are difficult to trade independently, the invention provides an identity authentication method based on non-homogeneous general certificates, which realizes identity authentication by using the non-homogeneous general certificates stored on a block chain and realizes casting, distribution, transfer, inquiry and destruction of the non-homogeneous general certificates through intelligent contracts.

The present invention is further described with reference to the drawings and the detailed description, it should be noted that the specific implementation of the present invention is based on the present technology, and the detailed implementation procedures and implementation procedures are given, but the scope of the present invention is not limited by the present implementation examples.
As shown in fig. 1 and fig. 2, a casting and distribution flow chart of the identity authentication NFT, a service provider, that is, a coinage party, invokes an intelligent contract to perform initial casting of the NFT, a user purchases the NFT corresponding to the identity right, and the main steps of the intelligent contract or the service provider distributing the NFT for the purchasing user are as follows:
step 1.1, intelligent contract deployment and initialization, wherein intelligent contracts used for casting non-homogenization evidence-based NFT under different protocol standards are compiled and deployed on a supported public chain, a supported alliance chain or a supported private chain respectively, so that the intelligent contracts can inherit contract interfaces of an ERC-721 protocol, an ERC-875 protocol and an ERC-1155 protocol respectively according to different protocol standards, and various functions of casting, verifying, transferring and destroying the non-homogenization evidence-based NFT are realized.
In step 1.2, the service provider, i.e. the coinage party, calls an NFT casting function castTokens (Chain, ERC, NFTname, NFTnum, valitytime, NFTprice, paymentAddress) to cast the identity rights NFT. Wherein, Chain needs to be the block Chain specified in the block Chain list for casting the non-homogeneous certified NFT, defaulting to etherhouse; ERC is a protocol standard which is selected by a coinage party from ERC-721 protocol, ERC-875 protocol or ERC-1155 protocol and is used for specifying that the casting non-homogenization protocol NFT follows, and the ERC-721 protocol is defaulted to; NFTname is the name of the non-homogeneous certification NFT to be cast; NFTnum is the total number of non-homogeneous witness NFTs to be cast; validityTime is the expiration date of the non-homogenization certification NFT to be cast, defaulted to one year; NFTprice is the selling price of the non-homogeneous general evidence NFT chain to be cast; paymentAddress receives the money address for the coinage party.
Step 2.1, a user, namely a service demander, purchases the NFT through a chain pay-on-the-go manner, initiates a transfer to a service provider and provides an address toAddr for receiving the corresponding NFT:
step 2.1.1 user registers wallet address of block chain corresponding to NFT, including private key SK C Public key PK C Address A C )。
Step 2.1.2 the user submits his own chained identity to the service provider and uses the private key SK C Signing the message, the service provider passing the public key PK C The signature of the purchasing user on the message is verified to confirm the authenticity of the identity on the chain.
Step 2.1.3, a user initiates a full-amount transfer to a specific address according to the price NFTprice calibrated by a service provider, and takes a quadruple < Chain, ERC, NFTname, toAddr > as additional transfer information, wherein the toAddr is used for receiving a casting-successful non-homogenization general evidence NFT and defaults to be the address for initiating the transfer.
Step 2.2.2 the user purchases the identity rights from the service provider by means of a trusted downlinked payment and provides the address toAddr for receiving the corresponding NFT.
Step 3.1 the smart contract automatically distributes NFT to purchasing users:
step 3.1.1, if the intelligent contract receives the sufficient amount of money transfer of the user, the four-tuple information provided by the user is used as a parameter to call an NFT distribution function distributeTokens (Chain, ERC, NFTname, toAddr) to perform NFT casting, the NFT is sent to a toAddr address given by the user, and the effective period of the address is recorded. Wherein the meaning of parameters of Chain, ERC and NFTname is the same as that of step 1.2, and the meaning of the toAddr parameter is the address of a user receiving NFT; and if the intelligent contract does not receive the user full-amount transfer, refusing to distribute the non-homogeneous certification NFT to the user address.
And 3.1.2, the intelligent contract inquires a coinage party collection address corresponding to the distributed NFT, and transfers the received money to the coinage party collection address.
Step 3.2 optionally, the service provider may manually distribute the NFT to the user:
and 3.2.2, the service provider takes the toAddr and the related information of the band casting NFT provided by the user in the step 2.2.2 as parameters, and calls an NFT distribution function distributeTokens (Chain, ERC, NFTname, toAddr) to distribute the corresponding non-homogenization certification NFT for the user. Wherein the meaning of the parameters of Chain, ERC and NFTname is the same as that of step 1.2, and the meaning of the toAddr parameter is the address of the user receiving NFT
As shown in the flowchart of identity authentication NFT verification in fig. 3, a user can use the owned non-homogeneous certificate NFT to authenticate the corresponding identity interest information to enjoy the corresponding interest, and the main steps are as follows:
step 4.1 the user connects to the service provider web site using a wallet tool such as MetaMask.
Step 4.2 the user accesses a specific identity-specific service or section.
Step 4.3 user uses private key SK C The authentication request data is signed.
Step 4.4 the service provider website uses the user public key PK C Verifying the signature data, determining needed identity authentication NFT information according to service resources requested by a user, calling an intelligent contract to perform identity authentication, and specifying a user address validaddr to be authenticated and an NFT name NFTname to be authenticated:
step 4.4.1, the intelligent contract takes the parameters as input, calls an NFT verification function validatekeys (Chain, ERC, validateAddr, NFTname) to verify whether the specified address holds the specified NFT, if the specified NFT holds the specified NFT, performs step 4.4.2, and if the specified NFT does not hold the specified NFT, returns a verification failure message. Wherein the meaning of parameters of Chain, ERC and NFTname is the same as that of step 1.2, and the meaning of validaddr parameter is the address of the user to be verified.
Step 4.4.2 specifies that the address holds the specified NFT and the smart contract verifies that it contains the destroy token destroyed.
And 4.4.3, if the destruction mark Destored is not included, calling an NFT validity period query function valityVerification (Chain, ERC, NFTname, < NFTid >) by the intelligent contract to perform NFT validity period query, wherein the meanings of the parameters of Chain, ERC and NFTname are the same as those of the step 1.2, and the NFT number NFTid is an optional parameter.
Step 4.4.4 the NFT validity query function queries the validity of a specific NFT, and if the NFT is not expired, returns a verification success message; and if the NFT is expired, returning a verification failure message.
Step 4.4.5, if the service provider receives the verification success message, providing a specific service or opening a specific edition block for the user; and if the authentication failure message is received, refusing to provide the specific service or opening the specific block.
As shown in the flow chart of transferring identity authentication NFT in fig. 4, non-homogeneous certificates NFT held by users can be freely transferred:
step 5.1 user a obtains user B NFT donation receiving address toAddr.
Step 5.2, the user A transfers the held NFT to the NFT gifting receiving address toAddr by using a wallet tool such as MetaMask, and takes < Chain, ERC, NFTname, NFTid, toAddr > as additional information of the transfer.
Step 5.3, the intelligent contract takes the address fromacaddr of the user a and < Chain, ERC, NFTname, NFTid, toAddr > as parameter inputs and calls the NFT transfer function transferTokens (Chain, ERC, NFTname, NFTid, froaddr, toAddr) to transfer the specific NFT from the NFT to transfer to the receiving address toAddr. Wherein the meaning of the parameters of Chain, ERC and NFTname is the same as that of the step 1.2, and the meaning of the NFTid parameter is the NFT number.
As shown in the flowchart of querying the validity period of the identity authentication NFT in fig. 5, any user may query the validity period of any non-homogeneous general certificate NFT:
step 6.1 the querier performs validity period query on the specific NFT:
step 6.1.1, the inquirer obtains a block Chain Chain where the NFT to be inquired is located, a protocol standard ERC, the NFT name NFTname and the NFT number NFTid.
Step 6.1.2 the inquirer initiates NFT to carry out validity period inquiry and attaches quadruple < Chain, ERC, NFTname, NFTid > information.
Step 6.1.3, the intelligent contract calls an NFT validity period query function validyVerification (Chain, ERC, NFTname, < NFTid >) to perform validity period query on a specific NFT, query the validity period of the specific NFT, and the NFTid parameter can not be omitted, wherein the meanings of the Chain, ERC and NFTname parameters are the same as that in step 1.2.
Step 6.1.4 the NFT validity query function returns the specific NFT validity time and whether the message is expired.
Step 6.2 optionally, the inquirer can inquire the valid period of the NFT with the same name in batch:
step 6.2.1, the inquirer obtains a block Chain Chain where the NFT to be inquired is located, protocol standard ERC and NFT name NFTname.
Step 6.2.2 Inquiry person initiates NFT to inquire validity period, and attaches triple information of < Chain, ERC, NFTname >
And 6.2.3, calling an NFT validity period query function validatityvalidation (Chain, ERC, NFTname) by the intelligent contract to perform validity period query on the NFT batch with the same name, wherein the meaning of the parameters of the Chain, the ERC and the NFTname is the same as that in the step 1.2, and in addition, the NFT numbering parameter NFTid can be omitted in batch query.
Step 6.2.4 the NFT validity query function returns all NFT validity times, holder addresses and if expired messages of the same name.
As shown in the flowchart of destroying the identity authentication NFT in fig. 6, the user can freely destroy the non-homogeneous certificate NFT held by the user, and the main steps are as follows:
step 7.1 the user initiates an NFT destroy request accompanied by four-tuple information<Chain,ERC,NFTname,NFTid,fromAddr>Using the private key SK C The kill request data is signed. .
Step 7.2 Smart contracts receive user requests, use the user public Key PK C Verifying the signature data and checking whether the NFT holding address fromAddr is the address for initiating the destruction operation.
If yes, step 7.3 checks if the NFT already contains the destruction flag destroyed. If not, returning the message of unauthorized destruction.
Step 7.4, if the destroy mark destroyed is not included, calling an NFT destroy function destroyTokens (Chain, ERC, NFTname, NFTid, fromAddr) to execute NFT destroy operation, and inputting the attached < Chain, ERC, NFTname, NFTid, fromAddr > as parameters, wherein the meaning of the parameters of Chain, ERC, NFTname is the same as that in step 1.2, the meaning of the parameter of NFTid is the NFT number, and the meaning of the parameter of fromAddr is the user address holding the NFT to be destroyed. If the destroy mark is contained, a destroy failure message is returned.
