Detailed Description
In order to make the technical solutions in the present specification better understood, the technical solutions in one or more embodiments of the present specification will be clearly and completely described below with reference to the accompanying drawings in one or more embodiments of the present specification, and it is obvious that the one or more embodiments described are only a part of the embodiments of the present specification, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from one or more of the embodiments described herein without making any inventive step shall fall within the scope of protection of this document.
Referring to fig. 1, a system architecture in an application scenario where a target user status label scheme based on a blockchain is determined according to an embodiment of the present disclosure is shown, in which the system may include a user terminal 102 and at least one service terminal 104, and each of the terminals may access a blockchain network 106. In addition, in some cases, the system may further include an authentication terminal 108. The number of the user terminals 102 is not limited, and only one is illustrated in fig. 1. The user terminal 102 may specifically be a terminal used by a target user, or may also be a terminal used by a verification user. The service terminals 104 may be terminals capable of collecting basic information and behavior information of target users and processing the information, and the service terminals 104 may be clients of various APPs or hardware devices installed with APPs. The service terminal 104 may belong to an internet organization or a public system in a certain field, so that information of a target user can be collected from multiple angles in multiple fields, and a tag representing a state of the target user more accurately can be obtained through processing.
Example one
Referring to fig. 2, a schematic step diagram of a method for determining a target user status tag based on a blockchain provided in an embodiment of the present specification is shown, where the method is applied to the system shown in fig. 1, and specifically may include the following steps:
step 202: the user terminal sends a state label query request to the block chain, wherein the state label query request carries the identity of the target user.
In this embodiment, the user terminal may be a mobile terminal of the target user, such as a mobile phone of the target user or an electronic device such as an IPAD; or it may be some type of client installed on the mobile terminal of the target user. In summary, the target user uses its own terminal to send a status tag query request for determining its own status tag to the blockchain. Alternatively, the first and second electrodes may be,
the user terminal may also be a terminal device of a verification party verifying the target user, such as a detector or verification device; or a certain type of client used for verification installed on the terminal equipment of the verifier, namely, the verifier sends a state label query request for determining a state label of a target user to the blockchain by using a terminal of the verifier.
It should be understood that the identity of the target user may be an identity assigned by the regulatory authority to each user for characterizing the unique identity of the user. In the embodiment of the present specification, the identification may be an identification number or other valid certificate numbers, or may also be a mobile phone number after real-name system. In fact, the identity may also be a unique serial number defined and distributed on the blockchain, and the serial number may be formed by various characters alone or in combination, which is not limited in this specification.
Step 204: after monitoring the status tag query request on the block chain, the at least one service terminal marks the identity information of the target user according to the acquired data and uploads a marking result to the block chain, so that the marking result is collected and integrated to obtain the status tag of the target user, wherein the marking result cannot be identified to the privacy data of the target user.
When the service terminal monitors the status label query request, the service terminal queries data of a target user from locally acquired data based on the identification of the target user carried in the status label query request, marks the identity information of the target user according to the data of the target user, and then uploads a marking result to a block chain so as to collect and integrate the marking result subsequently to obtain the status label of the target user. The data acquired by the service terminal may include: basic information of the target user and behavior information of the target user, wherein the basic information may include: basic attribute parameters such as name, gender, age, occupation and the like; the behavior information may be various types of behavior data related to the target user's clothing and housing, including: travel track, shopping consumption record, visit record, community entrance and exit registration and the like. In this embodiment of the present specification, the service terminal may mark the identity of the target user by default according to the user information by using a rule agreed in an intelligent contract on the block chain, and a specific marking mode is not limited in this specification.
It should be understood that the marking result uploaded to the block chain by the service terminal cannot identify the privacy data of the target user. In a specific implementation, the tagging result cannot be used to identify the private data of the target user, and the following scheme may be adopted:
1. the marking result is presented in a scoring form or a form of answer to the question, and does not represent data information of any actual attribute, such as a specific score, wherein the score is represented in a numerical value or a letter form, and further, for example, represented by answer to the question such as "yes" or "no".
Based on the scheme 1, when the status label of the target user is obtained by summarizing and integrating the marking result, a summarizing and integrating rule in a deployed intelligent contract can be called specifically by a block chain, and the marking result is processed to obtain the status label of the target user. That is, the determination operation of the status label of the target user is performed on the block chain, and since the labeling result is presented in the form of a score, the risk of privacy disclosure is reduced. And then, after the user terminal monitors that the processing is completed, the user terminal can acquire the state label of the target user from the block chain.
2. The marking results are encrypted, and the block chain is only stored in public and cannot be directly read by block chain nodes and external media.
Based on the scheme 2, the status label query request also carries a public key in a public-private key pair locally generated by the user terminal; then, after monitoring the status tag query request in step 204, the at least one service terminal marks the identity information of the target user according to the acquired data, and when uploading the marking result to the block chain, specifically executes: after monitoring the state label query request, the at least one service terminal acquires a public key uploaded by the user terminal; and marking the identity information of the target user according to the acquired data, encrypting the marked result through the public key after signing the marked result, and uploading the signed result to the block chain.
An implementable approach, after a user terminal sends a status tag query request to a blockchain, the method further comprising: the verification terminal sends a verification request to a block chain, wherein the verification request carries the identity of the target user; and after monitoring a verification request corresponding to the target user, the user terminal encrypts a private key in the locally generated public and private key pair and sends the encrypted private key to the verification terminal, and uploads authority information granted to the verification terminal to a block chain. The user terminal can encrypt its private key by using the public key of the verification terminal, and then send the encrypted private key to the verification terminal.
The reason why the authenticator requests the uplink is to ensure that the authenticator requires user authorization each time the authenticator uses the user data, so that the user can recover the right of the user according to the authorization record once the related agency illegally uses the user data.
Furthermore, when the status label of the target user is obtained by collecting and integrating the marking results, the verification terminal can obtain the marking results related to the target user after monitoring the granted authority information; the verification terminal decrypts the marking result according to the received private key and verifies the signature; and after the verification is passed, the verification terminal processes the marking result according to a locally set summarizing and integrating rule to obtain the state label of the target user. That is to say, under the condition that the verification terminal participates, the verification terminal may obtain the marking result from the block chain, decrypt the marking result by using the private key of the user terminal, verify the signature, and summarize the marking result, thereby obtaining the status label. In the process, the information of the target user is transmitted in an encrypted manner, and the marking result on the block chain is stored in an encrypted manner all the time and cannot be read by the block chain link point, so that privacy disclosure is effectively avoided.
The summary integration rule may be an integration manner set by the verification terminal according to its own requirement, for example, the summary integration rule may be a weighted average or an integration manner according to other priority rating manners, which is not limited in this specification.
An implementable scheme, based on scheme 1 or scheme 2, before the user terminal sends the status tag query request, the method further comprises: and the at least one service terminal applies for qualification authentication to the supervision terminal, wherein the service terminal has the authority to upload the marking result to the block chain after the authentication is passed.
It should be understood that, after the status label referred to in the embodiments of the present specification is returned to the user terminal, the target user status can be shown in a simple graphical and/or textual manner, for example, a graphical color represents different statuses, or a text such as excellent-good-not-good represents different statuses.
In this specification embodiment, if a user or verifier has a doubt about a determined status label, the server may be requested to re-label by means of an offline complaint in order to re-determine the status label.
The following describes a detailed description of a scheme for determining a target user status label based on a block chain according to a specific example.
Assuming that the health code during an epidemic situation is taken as an example, the target user may be a specific individual, and the corresponding identification of the target user may be an identification card. The service terminal can be a server of the traffic APP or a server of the consumption APP. Referring to fig. 3, suppose a user wants to enter a company to work, but considering that an epidemic situation is serious and it is uncertain whether the user goes to an epidemic area or contacts a crowd in the epidemic area, in order to ensure the health of the company colleagues, all employees entering the company need to be subjected to health verification, at this time, the target user may be the user, the verification party may be a company guard, the service party may be various APPs for collecting and processing information, and assuming that the service party 1 and the service party 2 are more than two in an actual scene, a plurality of service parties may be marked simultaneously and generally may be service parties in different fields.
Because the scheme is realized based on the block chain, not all service parties can upload information to the block chain, so that the service party can actively apply for qualification authentication by the service party monitoring party, and only after the qualification authentication, the service party is qualified or authorized to send the information to the block chain. Wherein, the blockchain can be developed and maintained by a supervisor.
The determination of the health code for the hair may include the following process:
the donkey hide wool sends a query request to the blockchain through the mobile phone.
And after monitoring the query request, the service part 1 and the service part 2 acquire the public key of the mobile phone broadcast.
The server 1 and the server 2 respectively mark the identity information of the donkey hide.
And the server 1 and the server 2 encrypt the signed marking result through the acquired public key and upload the signed marking result to the block chain.
The verification sends a verification request to the blockchain.
After the donkey hide wool monitors the verification request through the mobile phone, the local generated private key is encrypted and then sent to the verifying party.
The Aroma uploads the authority information granted to the verifying party to the block chain through the mobile phone.
And after monitoring the granted authority information, the verifying party acquires a marking result related to the hair.
And the verifying party decrypts the marking result according to the received private key and verifies the signature.
And the verifier processes the marking result according to a locally set summarizing and integrating rule to obtain the health code.
Then, the verifying party can determine whether to pass the donkey hide wool according to the health code, and simultaneously, the health code can be directly sent to a mobile phone of the donkey hide wool, so that the donkey hide wool can see the health code of the donkey hide wool. If the hair considers the status of the health code feedback to be not in accordance with the actual condition of the hair, for example, the hair does not contact or go to an epidemic area, but returns a red code which is not good for representing the health condition, the hair can be used for complaint correction. The specific complaints can be either online or offline, or can be implemented by a blockchain.
Through the technical scheme, the information of the target user can be cooperatively acquired through a plurality of service parties and marked; the defects in the aspects of data integrity and dimensionality can be avoided without excessively and intensively disclosing the information of the target user to a service party, so that the accuracy of the state label is improved, and the privacy of the user is protected to a certain extent. In addition, considering that the state label is determined by a multi-party marking result, the problems of data counterfeiting or hiding, false reporting and the like can be effectively avoided, and the authenticity of the state label is improved.
