the certificate storing server 13 is used for acquiring the block link certificate storing request and first equipment information for sending the block link certificate storing request; performing a matching check on the first device information and the second device information; and storing the license information to the license block chain 11 when the first device information is matched with the second device information.
The evidence storage block chain can be a judicial alliance chain consisting of judicial institutions such as courtroom, arbitration department and notarization department, and is in communication connection with the evidence storage server and the request client through preset client equipment.
The requesting client may be, for example, a client installed on an electronic device such as a mobile phone, a computer, etc. used by the user to provide a user interaction interface. The request client can initiate a block link verification request through a data network, and can realize the functions of one-stop verification, verification checking and the like of a user through the connection of a verification server.
The certificate storage server is a central hub of the system provided by the embodiment of the application, is in butt joint with the request client of the front end and the certificate storage block chain of the background, can receive the certificate storage request initiated by the request client, and can analyze and check information such as the certificate storage request.
The first device in the embodiment of the present application may be, for example, an electronic device such as a mobile phone and a computer used by a user.
The block chain evidence storing request may be determined by the requesting client according to the content that actually needs to store the evidence. And the second device information may be obtained by the requesting client by initiating a verification request to the gateway device, and the like.
The second device information corresponds to the certificate information, and specifically, the second device information may be information of an electronic device that generates the certificate information, or the second device information may be information of an electronic device that generates a block chain certificate request including the certificate information.
In this embodiment, the first device and the second device may be the same electronic device.
The credential storage server may directly receive a block chain credential storage request sent by the requesting client through the first device. In addition, the certificate storing server may obtain the first device information by requesting the client, or the certificate storing server may also obtain the first device information for sending the block chain certificate storing request by using the gateway device or other devices.
In addition, the device information described in this embodiment may be information capable of characterizing the identity of the device, for example, the first device information may be a mobile phone number when the first device is a mobile phone, and the first device information may be an ip address of a computer when the first device is a computer. Of course, the device information may also be other forms of information capable of characterizing the identity of the device, such as a two-dimensional code form, a barcode form, or a picture form.

Or, the blockchain credential storage request received by the credential storage server may be forwarded by the gateway device, and the gateway device may determine, after receiving the blockchain credential storage request sent by the request client, first device information for sending the blockchain credential storage request, and then send the blockchain credential storage request and the first device information to the credential storage server.

In practical applications, the second device generating the credential information may be the same as the first device sending the block chain credential request. For example, the user generates the certificate storing information through the mobile phone a and sends the block link certificate storing request through the mobile phone a, and at this time, the first device information and the second device information are both the information of the mobile phone a. When the certificate storage server side carries out matching verification on the first device information and the second device information, whether the first device information is consistent with the second device information or not is judged, if yes, the first device information is determined to be matched with the second device information, and then certificate storage is executed.
In addition, the first device and the second device may be different devices. For example, the user generates the certificate information through the computer B, that is, the second device information corresponding to the certificate information is the information of the computer B. And then, the user sends a block link certificate storing request through the mobile phone C, namely the first device information is the information of the mobile phone C.
When the certificate storing server executes matching verification on the first equipment information and the second equipment information, whether the information of the computer B is matched with the information of the mobile phone C can be judged. Specifically, it may be determined whether the computer B and the mobile phone C belong to the same user, or whether the information of the account registered by the client in the computer B is consistent with the information of the account registered by the mobile phone C, or whether the information of the computer B is matched with the information of the mobile phone C is determined according to the matching information obtained in advance.
By the scheme provided by the embodiment of the application, the information of the second device corresponding to the certificate storing information and the information of the first device sending the block chain certificate storing request can be matched and checked, so that the device corresponding to the certificate storing information and the device sending the block chain certificate storing request are both known and authorized devices of a user. And further, the fact that the evidence information is not forwarded or tampered by equipment unknown and risky by a user before uplink is determined, and therefore safety of the evidence information before uplink is guaranteed.

After storing the certificate storing information in the certificate storing block chain, the certificate storing server may further store the corresponding first device information in the service block chain, so as to store the first device information and the corresponding certificate storing information in an associated manner.
Specifically, the certificate storing server may send the certificate storing related information and the first device information to the service block chain after storing the certificate storing information in the certificate storing block chain. The intelligent contract for realizing the evidence storing transaction on the service block chain can associate the evidence storing hash value of the service block chain with the evidence storing serial number on the evidence storing block chain, and associate the first evidence storing equipment information, so that the associated storage of the first equipment information and the evidence storing information is realized. The certificate storing block chain can effectively record the association relation between the certificate storing information and the first equipment.

The certificate storing client can store the certificate storing record to the service block chain through the certificate storing server, specifically, the certificate storing client can send the certificate storing record to the certificate storing server, and the certificate storing server forwards the certificate storing record to the service block chain, so that the service block chain stores the certificate storing record and the first device information in an associated manner.
Optionally, based on the system provided in the foregoing embodiment, the certificate storing server 13 is further configured to:

and verifying the target verification information according to the target verification record.
In this embodiment, the first device may generate a blockchain verification request in response to a user operation, and send the blockchain verification request to the verification server. The blockchain verification request includes target device information, which may be first device information used when verifying the target verification information. When the target authentication information is stored, the target authentication information and the corresponding target equipment information are stored in a correlated manner, so that the correlated target authentication record can be verified according to the target equipment information, and the target authentication information can be searched.
For example, the user sends a block link certificate storage request in advance through the mobile phone D, and performs certificate storage on the certificate storage information. After the certificate storage is completed, the certificate storage record of the certificate storage information and the corresponding first device information are stored in the service block chain. When a user generates and sends a blockchain check request through the mobile phone D, the verification storage server can analyze target equipment information in the blockchain check request, and determines a verification storage record corresponding to the target equipment information through the service blockchain, wherein the verification storage record indicates the verification storage time of the target verification storage information corresponding to the target equipment information and the height of the blockchain for storing the verification storage information, and the target verification storage information can be determined in the verification storage blockchain according to the verification storage time and the height of the blockchain, so that verification is achieved.
Optionally, based on the system provided in the foregoing embodiment, as shown in fig. 4, the service block chain includes a service storage node 41;

The specific flow can be that the user mobile phone sends a verification request to the gateway device, and the verification request reaches the certificate storage server after passing through the gateway device. The gateway device may be a user plane network element device in an operator network, and may acquire user device information including a mobile phone number and the like passing through the network element.
When the mobile phone number verification request passes through the gateway device, the gateway device can acquire the mobile phone number sending the request through a data network, the gateway device sends the acquired mobile phone number sending the block chain evidence storage request as first device information and the block chain evidence storage request to an evidence storage service terminal, the evidence storage service terminal analyzes the block chain evidence storage request and the first device information after receiving the block chain evidence storage request and the first device information, and the mobile phone number filled by the user and acquired by the gateway are compared to verify whether the two mobile phone numbers are matched.

The request client sends a mobile phone number verification request to the gateway equipment based on the indication of the evidence storage client, the gateway equipment acquires the mobile phone number of the client sending the verification request, and sends the acquired mobile phone number and the evidence storage data packet to the evidence storage server, so that the evidence storage server compares the mobile phone number of the evidence storage data packet with the mobile phone number acquired by the gateway to determine a matching verification structure.
And after the verification matching of the certificate storage server is successful, sending a mobile phone number verification passing mark to the certificate storage client on the certificate storage block chain.
The certificate storing client stores the certificate storing data packet on the certificate storing block chain and returns the certificate storing number to the certificate storing server.
The certificate storing server side returns the certificate storing number to the request client side, and meanwhile, the user is reminded that the block chain has strong association with the certificate storing number, and the certificate can be checked and exported jointly through the mobile phone number and the certificate storing number.
Preferably, the service block chain performs twice data chaining operations in the certificate storing process, firstly chains the certificate storing hash value of the service block chain, the corresponding relation of the certificate storing data packet and the specific data value, secondly stores the mobile phone number information of the certificate storing data packet in advance, and secondly chains the corresponding relation of the mobile phone number and the certificate storing hash value and the specific data value.

As shown in fig. 6, during the verification:
when the user needs to check the target equipment information, the user fills in the mobile phone number information on the request client and sends a block chain checking request to the gateway equipment.
And then, the gateway equipment acquires the first equipment information after receiving the blockchain checking request, and sends the acquired first equipment information and the blockchain checking request to a checking server.
And after receiving the blockchain checking request and the first equipment information, the verification storage server matches and verifies the mobile phone number filled by the user and obtained by analyzing the blockchain checking request with the mobile phone number obtained by the gateway.
And after the matching verification of the certificate storing server is successful, sending a mobile phone number verification passing mark to the request client.
And the request client sends the successfully verified mobile phone number to the service storage node through the authentication server, and the service storage node searches the authentication information related to the mobile phone number.
And the request client sends the deposit certificate number filled by the user to the service storage node through the deposit certificate server, and the node finds the deposit certificate record corresponding to the deposit certificate number from the screened deposit certificate information.
The service storage node is positioned to the specific block information, and the corresponding evidence storage time and the corresponding block height can be found, namely returned to the requesting client.
