The block chain-based data acquisition method provided by the embodiment of the application is explained in detail below.
FIG. 3 is a flowchart illustrating a blockchain-based data acquisition method that is implemented in the implementation environment shown in FIG. 1, the method's execution subject may be a business server of a business processing organization, according to an exemplary embodiment. Referring to fig. 3, the method may include the steps of:
step 301: and receiving a service processing request sent by the user terminal, wherein the service processing request carries the user identifier, the user face image and the first block identifier.
The user identifier may be used to uniquely indicate a user, for example, the user identifier may be user information such as name, gender, age, identification card number, and mobile phone number of the user, which is not specifically limited in the embodiment of the present application.
Wherein the first tile identifier is used to indicate a storage location of medical cost data of the user in the blockchain system, and may be used to uniquely indicate one tile in the blockchain system.
Wherein the business process is business transaction between the user and the business processing mechanism. For example, the business process may be medical insurance reimbursement, social security reimbursement, or personal credit evaluation, which is not limited by the embodiment of the present application.
As an example, when a user wants to perform business processing at a business processing facility after medical consumption at the medical facility, a business processing request may be sent to a business server of the business processing facility through a user terminal. For example, the user information, the first block identifier and the face image of the user can be shot in real time for uploading through the user terminal on a service processing page provided by a service server of the service processing mechanism.
For example, after the user performs medical consumption in the medical institution, if the user wants to cancel the medical fee in the medical insurance institution, the user terminal may fill in the user information such as name, gender, age, identification card number and the like and the first block identifier in the service processing page provided by the service server of the service processing institution, and the user is required to shoot the face image in real time for uploading.
It should be noted that, the first block identifier may be input by the user at the service processing interface, or may be stored in the user terminal in advance.
In order to judge whether the face image uploaded by the user is photographed in real time or not and whether the face image uploaded by the user is photographed for a real person or not, a camera of the user terminal can be turned on when the face image uploading operation is detected, the face image of the user is photographed in real time, and the user can perform actions such as blinking and shaking.
Further, medical cost data may be sent by the medical server to a data server of the medical facility, which then stores the medical cost data into a first tile on the configured blockchain, and sends a first tile identification of the first tile to the medical server.
In some embodiments, referring to fig. 4, the medical server sends medical fee data to a blockchain configured by a data server of the medical institution, the data server of the medical institution triggers the smart contract to perform data verification when the medical fee data is received, the medical fee data can be stored in a first block in the configured blockchain when the format of the medical fee data meets the requirements of the smart contract, the first block can be a newly generated block in the blockchain before the medical fee data is received, and a first block identification of the first block is returned to the medical server.
Alternatively, the first block may be generated based on the healthcare cost data after receiving the healthcare cost data and the first block identification of the first block may be returned to the healthcare server.
It should be noted that, the staff of the medical institution may obtain the first block identifier from the medical server and provide the first block identifier to the user, that is, the user may learn the storage location of the medical fee data in the blockchain.
As an example, when each block in the blockchain is generated, referring to fig. 5, when the node where the blockchain is located receives the medical expense data, the medical expense data is verified, after the verification is completed, the medical expense data is stored in the memory pool, and the hash tree for recording the medical expense data is updated; then, updating the update time stamp to the time of receiving the medical expense data, and trying different random numbers to calculate the characteristic value for a plurality of 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 eigenvalue algorithm used to calculate eigenvalues; version (version number) is version information of the related block protocol in the block chain; the prev_hash is the block header characteristic value of the parent block of the current block; the merkle_root is a characteristic value of input information; ntime is the update time of the update timestamp; the nbits is the current difficulty, is a fixed value in a period of time, and is determined again after exceeding a fixed period of time; x is a random number; TARGET is a eigenvalue threshold that can be determined from nbits.
Thus, when the random number meeting the formula is calculated, the medical expense data can be correspondingly stored to generate the block head and the block main body, and the current block is obtained. And then, the data server of the medical institution sends the newly generated blocks to other nodes in the blockchain system according to the node identification of the other nodes in the blockchain system, the other nodes verify the newly generated blocks, and the newly generated blocks are added into the stored blockchain after the verification is completed.
That is, after the medical expense data is stored in the blockchain corresponding to the medical server of the medical institution, the medical expense data can be broadcasted, so that the data stored on each node in the blockchain system is the same, that is, the data server of the medical institution can synchronize the medical expense data with other nodes in the blockchain system, so that the data server of the business processing institution also stores the same medical expense data.
As an example, the medical server of the medical facility may also upload the recharge data of the user's visit card, prescription practice data, inspection data, nutrition assessment data, etc. to the blockchain corresponding to the data server of the medical facility for storage.
Step 302: and sending a verification information acquisition request carrying the user identifier to a data server of the service processing mechanism.
After receiving the service processing request of the user terminal, the service server of the service processing mechanism may send a verification information acquisition request carrying the user identifier to the data server of the service processing mechanism so as to acquire the face image of the user corresponding to the user identifier, match the face image of the user stored on the block chain with the face image sent by the user terminal, and determine whether the face image of the user stored on the block chain and the face image sent by the user terminal are the same person.
As an example, to improve the accuracy of the verification, the image capturing timestamp of the user face image may be carried when the user face image is sent to the service server of the service processing organization. If the user face image also carries an image shooting time stamp, when the time difference between the time indicated by the image shooting time stamp and the current time is smaller than a time difference threshold value, a verification information acquisition request carrying a user identifier is sent to a data server of a service processing mechanism.
The time difference threshold may be set by the user according to actual needs, or may be set by default by a service server of the service processing mechanism, which is not limited in the embodiment of the present application.
That is, when the user face image also carries an image capturing timestamp, a time difference between the time indicated by the image capturing timestamp and the current time may be determined, and when the time difference between the time indicated by the image capturing timestamp and the current time is smaller than a time difference threshold, the image capturing time of the user face image may be considered to be closer to the current time, or the user face image may be considered to be an image captured in real time, and the verification information acquisition request carrying the user identifier is sent to the data server of the service processing mechanism.
As another example, when the time difference between the time indicated by the image capturing timestamp and the current time is greater than the time difference threshold, it may be considered that the image capturing time of the user face image is relatively far from the current time, not captured in real time, the authenticity of the user face image cannot be determined, and a message of failure of service processing may be sent to the user terminal.
In order to more accurately determine that the user triggering the service processing is the user corresponding to the user identifier, the user face image needs to be determined to be shot in real time, and therefore the application judges whether the time difference between the time indicated by the image shooting time stamp and the current time is larger than the time difference threshold value, and the follow-up operation is executed when the time difference is larger than the time difference threshold value, so that other users can be prevented from using the image of the user corresponding to the user identifier to impersonate the user triggering the service processing, and the safety of the service processing is improved.
As an example, the service processing request further carries image capturing information, where the image capturing information is used to indicate a capturing manner of a face image of the user. When the time difference between the time indicated by the image shooting time stamp and the current time is smaller than a time difference threshold value and the image shooting information indicates that the acquisition mode of the face image of the user is a living body identification mode shooting, a verification information acquisition request carrying a user identification is sent to a data server of a service processing mechanism.
In some cases, some users may take photos of other users to obtain face images of the other users, and then apply for service by using the face images of the users, that is, the user who is not the user corresponding to the face images applies for service, and at this time, a certain potential safety hazard may exist. Therefore, the service server may be required to carry image capturing information in the service processing request when the service is applied, that is, not only the user face image needs to be determined to be captured in real time, but also the user face image needs to be determined to be captured in a living body recognition mode, and only when the two conditions are determined to be met, the service server sends a verification information acquisition request carrying the user identifier to the data server of the service processing mechanism.
The user terminal may open the camera and perform living body recognition by blinking, panning, nodding, or the like when detecting that the user face image is uploaded, and may take a picture when the action collected by the camera corresponds to the instruction, collect the user face image, determine that the collection mode of the user face image is a living body recognition mode, and generate image capturing information for indicating the living body recognition mode when sending the user face image to the service server, and send the image capturing information and the user face image to the service server.
The received face image of the user can be determined to be an image of a person shot in real time instead of a photo in a living body recognition mode, so that other users can be prevented from impersonating the face image of the user by using the picture shot in advance by the user corresponding to the user identification, and the safety of service processing is further improved.
Step 303: and receiving a face verification card sent by a data server of the service processing mechanism, wherein the face verification card is obtained from a block chain by the data server of the service processing mechanism, and comprises a face image of a user corresponding to the user identification.
In some embodiments, when the data server of the service processing mechanism receives the authentication information acquisition request sent by the service server of the service processing mechanism, the data server of the service processing mechanism may acquire a face authentication card corresponding to the user identifier from the blockchain, and send the face authentication card to the service processor of the service processing mechanism.
The blockchain may store a correspondence between the user identifier and the face verification card, that is, the blockchain may store face verification cards of different users.
As an example, referring to fig. 6, according to the user identifier carried in the authentication information obtaining request, the data server of the service processing mechanism obtains, from the blockchain, a face authentication card with the latest uplink time in at least one face authentication card corresponding to the user identifier. The face verification card includes a face image of the user corresponding to the user identifier, for example, the face verification card may include a face image on an identification card of the user corresponding to the user identifier, or the face verification card may include a face image uploaded by the user corresponding to the user identifier.
That is, if the number of face verification cards corresponding to the user identifier is one, when receiving a verification information acquisition request sent by a service server of the service processing mechanism, the data server of the service processing mechanism may acquire the face verification card corresponding to the user identifier from the configured blockchain according to the user identifier carried in the verification information acquisition request; if the number of face verification cards corresponding to the user identification is multiple, when receiving a verification information acquisition request sent by a service server of the service processing mechanism, a data server of the service processing mechanism can acquire the face verification card with the latest uplink time in the face verification cards corresponding to the user identification from the configured blockchain according to the user identification carried in the verification information acquisition request.
As an example, the data server of the service processing mechanism may determine, according to the user identifier, a block of the face verification card corresponding to the user identifier, where in a normal case, one user identifier may correspond to one block, and one face verification card of one user may be stored in the block, or face verification cards of multiple users may be stored in the block. When only the face verification card corresponding to the user identifier is stored in the block, the face verification card in the block can be directly obtained; when the face verification cards of a plurality of different users are stored in the block, the face verification cards corresponding to the user identifications can be obtained.
As an example, when the number of face verification cards corresponding to the user identifier is one, the data server of the service processing mechanism may directly obtain the face verification cards; when the number of the face verification cards corresponding to the user identification is multiple, the data server of the business processing mechanism selects the face verification card with the latest uplink time in the face verification cards according to the uplink time corresponding to each face verification card in the face verification cards, and acquires the face verification card with the latest uplink time.
After the data server of the service processing mechanism acquires the face verification card based on the face identification, the face verification card can be sent to the service server of the service processing mechanism so as to facilitate the service server of the service processing mechanism to carry out the authenticity verification of the face image and confirm whether the user corresponding to the user identification applies for service processing.
Further, the user terminal may send a verification information storage request to a data server of the service processing mechanism, where the verification information storage request carries a face verification card, and after the data server of the service processing mechanism receives the face verification card, the face verification card and the uplink time of the face verification card are correspondingly stored in a second block on the configured blockchain.
That is, the user needs to store the face verification card in the configured blockchain in advance through the user terminal, after receiving the verification information storage request sent by the user terminal, the data server of the service processing mechanism triggers the intelligent contract to verify the face verification card carried in the verification information storage request, and when the face verification card carried in the verification information storage request meets the requirement of the intelligent contract, the face verification card carried in the verification information storage request and the uplink time of the face verification card are stored in the second block on the blockchain configured by the data server of the service processing mechanism.
As an example, after receiving the authentication information storage request, a second block may be generated based on the authentication information storage request, and the face authentication card carried by the authentication information storage request and the uplink time corresponding to the face authentication card are stored in the second block.
It should be noted that, because the user's identification card needs to be replaced once at intervals, or the face changes with time, the user can upload multiple face images to the blockchain configured by the data server of the service processing mechanism at different times through the user terminal.
Step 304: and when the face image of the user is matched with the face image in the face verification card, determining that the face image of the user passes verification.
In some embodiments, the service server of the service processing mechanism matches the face image of the user sent by the user terminal with the face image in the face verification card sent by the data server of the service processing mechanism, and determines whether the face image of the user passes verification, so as to verify the identity of the user.
As one example, when it is determined that the user face image does not match the face image in the face verification card, it may be determined that the user face image verification fails.
It should be noted that, the steps 302 to 304 may be used to implement the operation of verifying the face image of the user according to the user identifier.
Step 305: when the face image of the user passes the verification, a fee acquisition request carrying the first block identifier is sent to a data server of the service processing mechanism, and the fee acquisition request is used for indicating the data server of the service processing mechanism to acquire medical fee data on the first block corresponding to the first block identifier from the block chain.
As an example, when it is determined that the verification of the face image of the user passes, the service processing request may be considered to be initiated by the user corresponding to the user identifier, and service processing may be performed, and the service server of the service processing mechanism may send a fee acquisition request carrying the first block identifier to the data server of the service processing mechanism, where the fee acquisition request is used to instruct the data server of the service processing mechanism to return the medical fee data stored on the first block corresponding to the first block identifier.
As another example, the service server of the service processing authority may send a service processing failure message to the user terminal when it is determined that the user face image verification is not passed.
That is, when it is determined that the user face image verification fails, it may be considered that the service processing request is not initiated by the user corresponding to the user identifier, and there may be a potential safety hazard, and service processing cannot be performed, and the service server of the service processing mechanism may send a service processing failure message to the user terminal.
Step 306: and receiving the medical expense data sent by the data server of the business processing mechanism.
After receiving the fee acquisition request carrying the first block identifier, the data server of the service processing mechanism can determine the first block according to the first block identifier, acquire the medical fee data stored on the first block, and send the medical fee data to the service server of the service processing mechanism, and the service server of the service processing mechanism receives the medical fee data sent by the data server of the service processing mechanism.
As an example, since the data stored in the blockchain configured on each node in the blockchain system is the same, although the medical fee data is transmitted to the blockchain corresponding to the data server of the medical institution, the same data is stored in the blockchain corresponding to the data server of the business processing institution, and thus the data server of the business processing institution can acquire the medical fee data from the blockchain corresponding to itself and transmit the medical fee data to the business server of the business processing institution.
After the service server of the service processing mechanism receives the medical expense data sent by the data server of the service processing mechanism, the service processing can be performed for the user corresponding to the user identifier based on the medical expense data. In this way, since the medical fee data stored in the blockchain has the characteristic of being unable to be tampered, the service server of the service processing mechanism directly acquires the medical fee data from the blockchain through the data server of the service processing mechanism, and the accuracy of the medical fee data can be ensured.
In the embodiment of the application, when the service server of the service processing mechanism receives the service processing request carrying the user identifier, the user face image and the first block identifier sent by the user terminal, in order to check whether the user triggering the service processing request is the user corresponding to the user identifier, the service server can check the user face image according to the user identifier, and when the user face image passes the check, the user triggering the service processing request can be considered to be the user corresponding to the user identifier, so that the service processing request is safe, and at the moment, the service server can send a cost acquisition request carrying the first block identifier to the data server of the service processing mechanism so as to acquire medical cost data on the first block corresponding to the first block identifier from the block chain of the data server of the service processing mechanism. That is, the service server can acquire the medical expense data from the blockchain of the data server of the service processing mechanism after the user is successfully checked, and the medical expense data stored on the blockchain is difficult to tamper because the blockchain has the characteristics of non-tampering, traceability and the like, so that the problem that the accuracy of the service processing is affected by the inaccuracy of the medical expense data can be avoided.
Referring to fig. 7, fig. 7 is a flowchart illustrating a blockchain-based data acquisition method according to another exemplary embodiment.
As an example, the user terminal sends a verification information storage request to a data server of the service processing mechanism, the verification information storage request carries a face verification card, and the data server of the service processing mechanism stores the face verification card and the uplink time of the face verification card into a second block on the configured block chain; the medical server sends the medical expense data to the data server of the medical institution, the data server of the medical institution stores the medical expense data into a first block on the allocated blockchain, the first block identification of the first block is sent to the medical server, and then the first block is broadcasted in the whole network, so that the medical expense data is also stored in the blockchain allocated by the data server of the business processing institution.
As an example, when a user wants to perform service processing, the user terminal may send a service processing request to the service server, where the service processing request carries a user identifier, a user face image and a first block identifier, after the service server receives the service processing request, if the user face image carries an image capturing timestamp and image capturing information, when a time difference between a time indicated by the image capturing timestamp and a current time is smaller than a time difference threshold, and the image capturing information indicates that an acquisition mode of the user face image is a capturing mode of living body identification, send a verification information acquisition request carrying the user identifier to a data server of the service processing mechanism, after receiving the verification information acquisition request carrying the user identifier, the data server of the service processing mechanism acquires a face verification card corresponding to the user identifier from a blockchain according to the user identifier, when the number of face verification cards corresponding to the user identification is a plurality of face verification cards, acquiring the face verification card with the latest uplink time, transmitting the face verification card to a service server by a data server of a service processing mechanism, matching a face image in the face verification card with a user face image transmitted by a user terminal, determining that the user face image is verified to pass when the face image in the face verification card is matched with the user face image transmitted by the user terminal, transmitting a cost acquisition request carrying a first block identification to a data server of the service processing mechanism by the service server, wherein the cost acquisition request is used for indicating the data server of the service processing mechanism to acquire medical cost data on a first block corresponding to the first block identification from a block chain, after receiving the fee acquisition request, the data server of the business processing mechanism acquires the medical fee data in the first block corresponding to the first block identifier from the block chain, sends the medical fee data to the business server, and the business server receives the medical fee data.
In the embodiment of the application, when the service server of the service processing mechanism receives the service processing request carrying the user identifier, the user face image and the first block identifier sent by the user terminal, in order to check whether the user triggering the service processing request is the user corresponding to the user identifier, the service server can check the user face image according to the user identifier, and when the user face image passes the check, the user triggering the service processing request can be considered to be the user corresponding to the user identifier, so that the service processing request is safe, and at the moment, the service server can send a cost acquisition request carrying the first block identifier to the data server of the service processing mechanism so as to acquire medical cost data on the first block corresponding to the first block identifier from the block chain of the data server of the service processing mechanism.
