The identity authentication method based on the blockchain specifically includes the following steps S302 to S310.
S302, receiving a service request of a user, and obtaining authorization information of the user according to the service request.
the service request is a request sent to a server of a service provider when the user needs the service provider to provide a service for the user. In one embodiment, the service request carries authorization information for the user. In another embodiment, a server receives a service request of a user, sends an authorization request to a user terminal according to user terminal information carried by the service request, and receives authorization information fed back by the user terminal based on the authorization request. The authorization information may be a fingerprint of the user, a face image of the user, a randomly generated password, or the like. The server of the service provider can generate a two-dimensional code corresponding to the authorization request, the two-dimensional code can be posted in specific application scenes of the service provider, such as hotel lobbies, business halls and the like, and a user can automatically scan and upload authorization information through a jump interface of the two-dimensional code when needing to request service. The server may transmit the request to the user terminal when receiving the request transmitted from the user through the terminal. In one embodiment, a user scans a two-dimensional code provided by a service provider by using terminal equipment such as a functional mobile phone and a tablet, the terminal equipment jumps to an interface corresponding to the two-dimensional code, and the interface prompts the user to authorize to acquire personal information of the user, and the personal information is specifically used for what purpose. For example, when a user checks in a hotel, the user scans an authorization verification two-dimensional code provided by the hotel, and can know through a two-dimensional code skip interface, the authorization request object is the hotel, the authorized personal information is the identity information of the user, and the purpose is to check the identity validity of the user. For another example, when a user opens an account in a bank, the user scans an authorization verification two-dimensional code provided by the bank, and can know that the authorization request object is an opening bank, the authorized personal information is a user name, an identification number, a mobile phone number and the like, and the purpose is bank opening.
the authorization information is used for checking the personal information of the user in a block chain, the block chain comprises a series of blocks which are connected with each other according to the generated time sequence, once a new block is added into the block chain, the new block cannot be removed, and the recorded data submitted by the nodes in the block chain system are recorded in the blocks. The node having the data submission authority is a client of an authority for managing citizen information, such as a public security bureau, a police station, and the like. In order to protect the privacy of the personal information of the user, the user can request to store the personal information into the blockchain, so that the identity authentication can be completed only by authorization in various application scenes, and specific certification materials are not required to be provided. In an embodiment, a user may provide proof of identity material to an authority, which may include, in addition to identification card information, the user's fingerprint, image, name, gender, native place, mobile phone number, and the like. The authority verifies whether the identification material is accurate, if so, the result that the user has finished personal identification authentication is returned, and the identification material is uploaded to the block chain. In addition, when the identification material is verified to be accurate and correct, the authority can perform hash operation on the verified identification material to obtain a hash value, and the hash value is uploaded to the block chain.
In one embodiment, as shown in fig. 4, the process of writing user personal information into the block chain includes steps S402 to S404.
S402, receiving a registration request, using the user personal information carried by the registration request as registration data, generating a data block, and adding the data block to a block chain.
s404, performing consensus processing on the data blocks at each node of the block chain through a consensus mechanism.
The authoritative mechanism client serves as a node in the identity authentication block chain network, a block chain which is the same as other nodes is stored, the block chain is composed of a plurality of blocks, and the node can write user personal information into a block main body of the block chain to realize uplink of the user personal information and registration data.
In one embodiment, the process of writing block chain of user personal information includes: the method comprises the steps that a lease message is used as input data of a block chain, input information is verified, after verification is completed, the input information is stored in a memory pool, and a hash tree used for recording the input information is updated; and then, updating the updating time stamp to the time when the input information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can meet the following formula:
SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))＜TARGET
Wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits. When the random number meeting the formula is obtained through calculation, the input data can be correspondingly stored, and a block head and a block main body are generated to obtain the current block. And then according to a common identification mechanism, the node where the block chain is located respectively sends the newly generated blocks to other nodes in the identity authentication block chain network according to the node identifications of the other nodes in the identity authentication block chain network, the newly generated blocks are verified by the other nodes, and the newly generated blocks are added into the block chain stored in the newly generated blocks after verification is completed, so that the input data are written in. Wherein, other nodes for realizing the consensus are clients corresponding to other authorities. The server of the service provider can be used as a node to be added to the identity authentication blockchain network and establish connection with the identity authentication blockchain network, but the server of the service provider can only read data in the blockchain under the authorization of the authorization node.
s304, searching a target block corresponding to the authorization information from the block chain.
In an embodiment, a server of a service provider, acting as an identity-authenticated blockchain network node, may read blockchain data under the authorization of an authorization node of the blockchain. And when the server acquires the authorization information of the user, searching a target block corresponding to the authorization information from the block chain. The block chain is composed of a plurality of blocks, and the target block is a block in which the registration information of the user is stored.
In an embodiment, the storage content tag corresponding to the authorization information may be searched for according to the storage content tag of the block chain, and the block carrying the storage content tag is used as the target block.
In another embodiment, the authorization information is a feature value obtained by calculating the personal information of the user through a preset feature value encryption algorithm, and the feature value is compared with the stored feature value in the block chain in a traversing manner to obtain a target block containing the stored feature value which is the same as the feature value.
in order to ensure that the user authorization information is not attacked and leaked, when the user sends the authorization information, the authorization information can be encrypted to obtain a characteristic value. The storage characteristic value refers to a characteristic value obtained by encrypting each item of personal information of the user and stored in the block chain. Specifically, when writing user personal information into a block chain, an authority firstly records the user personal information according to whether a user corresponding to the user personal information is a registered user or not, and generates a key pair of the user according to the user personal information if the user is not registered, wherein the key pair comprises a private key and a public key, and sends the key pair to the user, and then stores the user personal information and the public key corresponding to the user in the block. In the searching process of the target block, the hash value corresponding to the authorization information is compared with the hash value stored in the block, and when the hash value identical to the hash value corresponding to the authorization information exists in the block main body of one block in the block chain, the block is the target block. In the data writing process, the same block contains a plurality of items of data of the same user, but the data of the same user is stored in the same block, and the identity authentication of the user can be carried out by finding the target block for storing the personal information of the user, so that whether the user meets the identity authentication requirement corresponding to the service request or not is determined.
S306, obtaining the registration data of the user corresponding to the authorization information from the target block.
In an embodiment, one tile may store registration data of multiple users, and the registration data of the users may be plaintext data or encrypted data. Firstly, according to the storage characteristic value matched with the characteristic value of the authorization information, a target user corresponding to the storage characteristic value is determined, during storage, various personal information can be associated, and the characteristic value of each personal information of the user can be obtained as long as the corresponding storage characteristic value is determined.
in one embodiment, as shown in fig. 5, acquiring the registration data of the user corresponding to the authorization information from the target block includes steps S502 to S506.
S502, extracting the private key carried in the authorization information.
S504, the private key is adopted to decrypt the storage characteristic value in the target block.
S506, the storage characteristic value which is decrypted successfully is used as the registration data of the user.
The registration data of the user is obtained by encrypting a public key in a key pair, and the private key can be used for decrypting the data encrypted by the public key when the private key and the public key form the key pair through the private key in the authorization information. For example, the characteristic value a is data encrypted by the public key of the user a, the characteristic value B is data encrypted by the public key of the user B, the public key of the user a is different from the public key of the user B, and only the characteristic value a can be decrypted by the private key of the user a to obtain plaintext information corresponding to the characteristic value a, and the decryption cannot be completed on the characteristic value B.
s308, when the authorization check is passed, calling the intelligent contract corresponding to the service request, executing the stated identity authentication logic by the intelligent contract, and obtaining the identity authentication result based on the registration data.
According to service constraint conditions of different service requests, corresponding intelligent contracts can be deployed in a blockchain in advance, and according to the type of the service request, the intelligent contracts corresponding to the type of the service request can be called from the blockchain. Specifically, the invocation may be implemented by redeploying the smart contract to set the corresponding identification. For example, the service constraint condition of the intelligent contract corresponding to the hotel check-in service is that the user is a legal user, and for example, the service constraint condition of the intelligent contract corresponding to the internet bar internet service is that the age of the user is more than 18 years. The intelligent contract corresponding to the service request is called, the intelligent contract executes the stated identity authentication logic, and when the intelligent contract executes the logic, the corresponding registration data is called for judgment through the triggering condition, so that the identity authentication result is obtained.
in one embodiment, the method further comprises executing the declared authentication logic by the smart contract, and obtaining the authentication result based on the registration data comprises: determining the user data attribute of target data to be called according to the identity authentication logic; searching and calling target data which accord with the user data attribute from the registration data of the user; when the target data meets the identity authentication logic, obtaining an identity authentication result that the user is a registered user and meets the service condition; and when the target data does not meet the service condition, obtaining an identity authentication result that the user is a registered user but does not meet the service condition.
the target data to be called is data for judging whether the data conforms to the identity authentication logic, and the user data attribute is specific attribute of the data, such as age, gender, name family and the like. And searching and calling target data which accord with the user data attribute from the registration data of the user according to the determined user data attribute, obtaining an identity authentication result that the user is the registered user and meets the service condition when the target data meet the identity authentication logic, and obtaining an identity authentication result that the user is the registered user and does not meet the service condition when the target data do not meet the service condition. In addition, when the target block corresponding to the verification information does not exist in the block chain, the identity authentication result that the user is not the registered user is obtained.
And S310, feeding back an identity authentication result.
in an embodiment, the identity authentication result may be fed back to the terminal of the service provider or the user terminal sending the service request, or may be sent to both the terminal of the service provider and the user terminal sending the service request.
According to the identity authentication method based on the block chain, the authorization information of the user is obtained according to the user request, the registration data of the user is searched through the block chain, the identity authentication of the user identity is realized through an intelligent contract corresponding to the service request, for a service provider, an identity authentication result is obtained, in the authentication process, the identity information of the user cannot be directly contacted, the real identity of the authorized user can be verified by utilizing the characteristic and privacy of the block chain data which are not easily tampered, the identity authentication result fed back by the block chain can be obtained or used only on the premise that the user is authorized, for the user, the user can be prevented from directly providing the identity information of the user for a merchant, and the problem that personal information of the user is leaked from the source is avoided.
In one embodiment, the service request is a hotel stay request; when the target data meets the identity authentication logic, after obtaining an identity authentication result that the user is a registered user and meets the service condition, the method further comprises the following steps: receiving hotel check-in data of a user; and generating check-in information according to the hotel check-in data and the authorization information, and writing the check-in information into the block chain.
when the user identity authentication is completed and the user meets the service condition of the hotel check-in request, the server receives hotel check-in data of the user, wherein the hotel check-in data specifically comprises a room number, check-in time and check-out time, the server generates check-in information according to the hotel check-in data and authorization information, and writes the check-in information into a block chain, wherein the block chain can be a block chain in a network with the identity authentication block chain or a block chain in other block chain networks, for example, a block chain in a hotel service data block chain network formed by clients of all hotels. The hotel check-in data and the authorization information of the user are synchronized to the block chain, so that the identity information of the user and the hotel check-in information are stored and shared in the whole block chain, when the user arrives at the hotel and checks in, the user does not need to register personal information again, and the safety of the personal information of the user is ensured.
in one embodiment, the hotel stay data includes a room number, a stay time, and a check-out time; generating check-in information according to the hotel check-in data and the authorization information, and writing the check-in information into the block chain, the method further comprises the following steps: generating a key pair carrying time conditions according to the check-in data and the authorization information, wherein the time conditions correspond to check-in time and check-out time; and pushing a first key in the key pair to an intelligent lock terminal corresponding to the room number, and pushing a second key in the key pair to a user terminal corresponding to the authorization information.
In order to avoid the situation that other users hold the users corresponding to the users to replace the users to stay in the hotel, after the identity information of the users is registered on the block chain, the users unlock the intelligent locks of the rooms by configuring keys, a first key in the key pair is pushed to an intelligent lock terminal corresponding to the room number, a second key in the key pair is pushed to a user terminal corresponding to the authorization information, and when the intelligent locks receive the encrypted data encrypted through the second key, the encrypted data are decrypted through the first key and verified.
In an embodiment, the application scenario of fig. 6 is taken as an example to describe the identity authentication method based on the blockchain in the present application.
The user provides identification material to the authority, which may include the user's fingerprint, image, name, gender, native place, mobile phone number, etc. in addition to the identification card information. The authority verifies whether the identification material is accurate, and if so, the result that the user has finished personal identification authentication is returned. In addition, when the identification material is verified to be accurate and correct, the authority can perform hash operation on the verified identification material to obtain a hash value, and the hash value is uploaded to the block chain. When a user performs a service such as transaction or check-in of a certain service, a service provider initiates an authentication request to the user to request the user to input identity information for authorization authentication. When a user receives a verification request, identity information is input, and hash operation is performed on the identity information to obtain a hash value. And the service provider uploads the obtained hash value to the block chain, and the hash value uploaded by the service provider is compared with the hash value stored in the block chain through the block chain to obtain a verification inquiry result. When the hash value of the user identification material is stored in the blockchain, the verification query result can be the user identification information without error. When the hash value of the user identification material is not stored in the blockchain, or the identification information provided by the user is incorrect, the verification query result may be that the identification information of the user does not exist. In one embodiment, to prevent information leakage when a user provides identification material to an authority, the authority may be checked to determine if it is a true and reliable authority.
