These terms are only used to distinguish one type of information from another. For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present specification.

Government administration, which typically includes the process of handling the lives of people by various government regulatory bodies, such as floating population management, social security medical insurance registration, deposit and withdrawal of public accumulation, deposit and withdrawal of accumulated points, and the like. In the traditional solution, the management department usually divides the sub-departments according to the specific project of the government affair treatment, which can make the staff in the sub-departments concentrate on a specific project in the government affair treatment without processing other affairs, thereby improving the specialization level of the government affair treatment and the single-piece treatment efficiency; moreover, the management department can also establish a government hall containing the reception windows of all the sub-departments, so that the time wasted by the people going to the sub-departments respectively is reduced.
For example, Zhang III is the due graduate of the work of the X city, and when the Ministry comes to the X city, the Ministry needs to handle temporary living procedures, social insurance procedures, talent subsidy procedures and the like.
Although the scheme can improve the handling efficiency of government affairs handling of the management department to a certain extent and shorten the time consumed by people for handling related businesses, the scheme is still a centralized system provided by the government management department in essence, and the safety and the transparency of the system still have space for improvement; for example, once a hacker invades, the services of all the sub-departments concentrated together may be affected, and there is a security risk; moreover, the computer system of the scheme is completely responsible for government administration departments, has poor disclosure transparency and is not beneficial to being supervised by the masses.
In this regard, the present specification proposes a distributed electronic government affair processing technical scheme, which performs identity authentication on citizens requesting government affair processing and each government affair processing platform based on a block chain and a decentralized identity mechanism, and performs decentralized identity validity check on the request and result of each government affair processing task.
When the government affair processing is realized, citizens requesting the government affair processing can use the client end butted with the block chain to send government affair processing requests to a government affair office platform which is also butted with the client end, and the government affair office platform can return the government affair processing results to the client end after the corresponding government affair processing is finished; the government affair processing request and the government affair processing result can carry decentralized identity signatures corresponding to the sender, and the party receiving the government affair processing request or the government affair processing result can carry out validity check on the government affair processing request or the government affair processing result by calling decentralized identity checking service provided by the block chain.
By applying the scheme, on one hand, in the government affair processing system, decentralized identities of citizens and government affair office platforms are managed and verified by block chains, and the block chains are distributed systems based on the cryptology principle and formed by a plurality of nodes and are difficult to attack and tamper, so that the safety of the government affair processing system can be improved compared with a traditional government affair hall.
On the other hand, in the process that the citizen requests the government affair office platform to perform government affair processing by using the client, the citizen and the government affair office platform use the corresponding decentralized identity to perform signature verification, so that the information sent by the citizen and the government affair office platform cannot be repudiated, and the transparency of the government affair processing system can be improved by the scheme.
The present specification is described below with reference to specific embodiments and specific application scenarios.
Referring to fig. 1, fig. 1 is a diagram illustrating an exemplary architecture of a block chain and decentralized identity based government affairs processing system; wherein, the system can comprise the following components:
the block chain 101 is used for managing decentralized identities of citizens and decentralized identities of government affair office platforms and providing decentralized identity verification service in the government affair management process;
the client 102 connected to the block chain is used for initiating a government affair processing request based on the decentralized identity of the citizen and calling the decentralized identity verification service of the block chain to carry out validity verification on the government affair processing result after receiving the government affair processing result;
and the government affair office platform 103 which is connected to the block chain is used for responding to the government affair processing request initiated by the client, carrying out corresponding government affair processing after calling the decentralized identity verification service of the block chain to carry out legality verification on the government affair processing request, generating a government affair processing result carrying the decentralized identity signature of the government affair office platform, and returning the government affair processing result to the client.
It should be noted that fig. 1 above only shows 1 client 102 and 1 government office platform 103, which is only an example for convenience of description; in the block chain and decentralized identity based government affair processing system described in this specification, the number of the above clients 102 and government affair office platforms 103 is not limited in this specification; for example, if the system supports 1000 citizens handling business simultaneously, the number of the clients 102 connected to the block chain 101 may reach 1000, and if the system supports social security registration, accumulation fund extraction, and multiple government affairs handling types, then multiple government affairs handling platforms 103 may exist in the system to support the multiple government affairs handling types.
The block chain 101 may include any type of block chain. The block chain technology, also called as distributed account book technology, is a technology in which a plurality of computing devices participate in accounting together and maintain a complete distributed database together; in general, blockchains have the characteristics of decentralization, public transparency, participation in database records by each computing device, and rapid data synchronization between computing devices. Blockchains are generally divided into three types: public chain (Public Blockchain), Private chain (Private Blockchain) and alliance chain (Consortium Blockchain). Furthermore, there may be a combination of the above types, such as private chain + federation chain, federation chain + public chain, and so on. In general, various types of blockchain properties may differ, and thus may be used to meet different technical requirements; for example, if the highest degree of decentralization is desired, a public chain may be selected; federation chains, etc., may be selected if desired to compromise decentralization and performance. In implementation, if the blockchain is in a form of a federation chain, the blockchain nodes forming the blockchain can be provided by various entities such as related management departments, common people, enterprises and the like respectively, so as to ensure that the block chain accounting right is relatively fair and reasonable; for another example, if the block chain is in a public chain form of an ether house, a general intelligent contract can be used for constructing related functions, and higher credibility is obtained; it can be seen that various types of blockchains are advantageous, and those skilled in the art can select the type of blockchain according to specific requirements without limiting the specific type of blockchain in the present specification.
It can be understood that the above block chain may interact with the outside through a block chain as a Service (BaaS) platform. Generally, BaaS platforms can provide flexible and customizable blockchain services to client-side computing devices connected to BaaS platforms by providing pre-written applications for activities that occur on the blockchain (such as subscription and notification, user authentication, database management, and remote updates). For example, in one example, where a client or a government office platform needs to communicate data with a blockchain, the BaaS platform may provide a service application such as MQ (Message Queue); a client or a government office platform connected with the BaaS platform can subscribe an intelligent contract deployed on a certain block chain in a block chain system connected with the BaaS platform, and a contract event generated on the block chain after triggering execution; and the BaaS platform can monitor the event generated on the block chain after the intelligent contract is triggered to be executed, and then adds the contract event into the message queue in the form of notification message based on the software related to MQ service, so that the client or the government office platform subscribing the message queue can obtain the notification related to the contract event.
The client 102 may be any client software capable of interfacing with the blockchain; in this specification, the main functions that the client may provide may include: acquiring input content of citizens, initiating a government affair processing request based on decentralized identity of citizens, calling decentralized identity verification service of a block chain to carry out validity verification on the government affair processing result, and the like; therefore, the present specification does not need to limit the specific form, and the application may be a conventional x86 executable application running on a desktop computer, a mobile application running on a mobile platform such as IOS and Android, a Web application based on a Web page, or a plug-in or applet embedded in another application, or the like. Different application forms can meet different requirements, for example, if the client is realized by adopting a Web application mode, the Web client does not need to be installed generally, and only equipment can normally access a network and render a webpage for execution, so that the convenience of the client can be greatly improved; for another example, if the client is implemented in the form of embedded software bound to hardware such as a specific business teller machine, the stability of the client can be greatly improved and abnormal situations that need to be considered in the operation and maintenance process can be reduced due to the fixed and safe operating environment. As mentioned above, the number of the clients 102 may be plural, in which case, the clients 102 may include various forms; for example, the system can comprise a mobile phone client to facilitate citizens to initiate government affair handling requests anytime and anywhere, and can also comprise a form of embedded software to facilitate citizens to be provided with services in a telephone booth, an automatic teller machine and the like.
The government office platform 103 may include software for digital office, such as social security registration system, real-name authentication system, etc.; in this specification, the government office platform interfacing with the blockchain may have functions of invoking a decentralized identity verification service of the blockchain to perform validity verification on the government affair processing request, performing government affair processing, generating and returning a government affair processing result carrying a decentralized identity signature of the government office platform, and the like; moreover, although the government office platform 103 has a different function from the client 102, it may be similar to the client 102; for example, the government office platform may be a conventional x86 executable application running on a desktop computer, a mobile application running on a mobile end platform such as IOS and Android, a Web application based on a Web page, or a plug-in or applet embedded in another application. The form of the government office platform can be selected by the person skilled in the art according to specific needs.
As mentioned above, the number of the government office platforms 103 can be plural, in this case, the plural government office platforms can also take different implementations; for example, in the case of an operator located in an office, the government office platform may be an x86 executable running on a desktop or a computer screen-adapted Web application; when the personnel in the relevant departments need to leave the office and arrive at the field to execute the official business, the government office platform of the mobile terminal App can be used, and the requirement of mobile office is met.
In the art, Decentralized IDentity (DID) is generally understood as an IDentity authentication mechanism that may contain identification and document, with global uniqueness, high availability resolvability and encryption verifiability. A decentralized identity may be said to be associated with a blockchain if the decentralized identity depends on a blockchain implementation. In implementation, a typical decentralized identity may be represented by the following character string:
did:example:123123123123abcabcabc
wherein, the did part is a system identification for indicating that the character string is a decentralized identity; the example part is a DID method identifier used for indicating the method on the block chain on which DID specifically depends; the 123123123123abcabc part is an identifier specified in the DID method, typically corresponding to a pair of public and private keys held by the individual whose identity corresponds to. The decentralized identity document may include an identity public key corresponding to the DID, a corresponding encryption algorithm, and other information, and may be used to verify the decentralized identity. For example, assuming that a user, zhang san sends a piece of information, which carries a signature of a decentralized identity and a DID identifier, other users can check the validity of the decentralized identity signature only by finding the decentralized identity public key of zhang san from the block chain according to the DID identifier, and if the check is passed, the sender of the information can be proved to be a person who holds the private key of zhang san of the user, that is, zhang san self.
The above block chain and decentralized identity based government affair processing system will be described from the flow point of actual government affair processing.
Because the government affair processing system is realized based on the block chain and decentralized identity, the expected government affair processing task can be completed only when the citizen and government affair office platform has decentralized identity in the government affair processing system based on the block chain and decentralized identity. Referring to fig. 2, fig. 2 is a flowchart illustrating a process for creating a decentralized identity according to the present disclosure; in an embodiment shown, for a citizen, a decentralized identity new establishment request of the citizen can be initiated to the block chain by the client 102, wherein the decentralized identity new establishment request of the citizen carries identity information input by the citizen; generating a first public and private key pair corresponding to the citizen; and responding to the new request of the decentralized identity of the citizen by the block chain, generating the decentralized identity of the citizen, and adding the public key in the first type of public and private key pair into the decentralized identity document of the citizen so as to deposit the certificate in the distributed account book of the block chain.
Similarly, in another embodiment shown, for the government affair office platform, a decentralized identity new establishment request of the government affair office platform can be initiated to the block chain by the government affair office platform, wherein the decentralized identity new establishment request of the government affair office platform carries identity information input by the government affair office platform; generating a second public and private key pair corresponding to the government affair office platform; and then, responding to a decentralized identity new establishment request of the government office platform by the blockchain, generating a decentralized identity of the government office platform, and adding a public key in the second type of public and private key pair into a decentralized identity document of the government office platform so as to store the certificate in a distributed account book of the blockchain.
As can be seen, the first public and private key pair corresponds to a citizen, and the second public and private key pair corresponds to a government affair processing task; this represents a point where decentralized identity is different from traditional documents, i.e., decentralized identity can label any entity with identity and is not limited to natural persons. It is understood that the decentralized identity of the first type is essentially the embodiment of the citizen identity in the government affairs processing system based on the block chain and decentralized identity, and is not necessarily bound to the client 102; however, one skilled in the art should also foresee that, in order to implement stricter access restrictions, the citizen identity may also be bound with the client, so as to implement the effect of one person for one machine and preventing fraudulent use.
It will also be appreciated that the process of creating decentralized identity is not necessarily a function provided by the block chain and decentralized identity based government affairs processing system of the present specification. If decentralized identities of clients and government office platforms are pre-configured in the blockchain, the basic government management functions can be realized even if the blockchain and decentralized identity based government management system does not provide the function of creating decentralized identities.
Referring to fig. 3, fig. 3 is a flow chart illustrating a single platform government affairs process according to the present disclosure; in this example, a government affair processing request carrying a decentralized identity signature of a citizen may be initiated by the client; the government affair office platform responds to the government affair processing request initiated by the client, performs corresponding government affair processing after calling the decentralized identity verification service of the block chain to perform legality verification on the government affair processing request, generates a government affair processing result carrying the decentralized identity signature of the government affair office platform, and returns the government affair processing result to the client; and finally, the client calls a decentralized identity verification service of the block chain to carry out validity verification on the government affair processing result, and if the result passes the validity verification, the government affair processing is finished.
For example, assuming that floating population a is a population newly entering a city, a house is found in the city, and the social declaration app is used to fill out the renting information, the renting information is stored on the blockchain 101 as data associated with the DID document of the floating population a, and if the floating population a applies for house accumulation extraction for relieving the house pressure, the house accumulation extraction is performed on the name of the house. In this case, after receiving the extraction request, the building department system may query the renting information of a through the block chain 101, perform DID signature verification on the information, after confirming the house renting information of a, match the renting information with the reason for the withdrawal application of the public deposit proposed by a, and after matching successfully, handle the service of withdrawing the public deposit for the building department system; the finished receipt can also prove to the floating population A that the processing task of the house accumulation fund extraction is finished in a similar DID signature verification mode.
Referring to fig. 4, fig. 4 is a flowchart illustrating an exemplary flow of a cross-platform government process; in some cases, the government affairs process to be applied by the citizen may require the participation of more than one relevant department, and in the related art, the citizen is generally required to run among a plurality of departments or windows, or cooperate with office software to perform information synchronization to complete the government affairs processing task across platforms. In an illustrated embodiment, the government office platform may include a front government office platform and a main government office platform; when the corresponding government affair processing is carried out on the main government affair office platform, a decentralized identity signature carried by the prepositive government affair data provided by the prepositive government affair office platform can be obtained and verified firstly; and if the verification is passed, further executing government affair processing of the main government affair office platform based on the preposed government affair data. By analogy, if three or more departments need to cooperate, the front government office platform and the main government office platform can be divided according to the sequence of business handling, for example, two front office platforms and one main government office platform, and then the scheme is executed.
For example, assuming that a floating population couple brings a child to go to school in a city, the school needs to meet the corresponding score entrance standard. The entrance point standard covers a plurality of data such as parental academic calendar, renting room information, membership information and the like, so that the couple can put forward service certificate handling applications in a plurality of government departments such as a residence and construction office, an education office and the like; after receiving the application, each department checks the digital identity of the member at the mouth, and after the check is passed, the department transacts the business certificate for the couple and signs the business certificate by using respective DID information; after the couple takes the business certificate, submitting the business certificate as preposed government affair data to a corresponding school, carrying out DID (do it yourself) label checking on the business certificate by the school through an education bureau system, and after the label checking is passed, transacting the business of entering school for the child according to the policy. Similarly, a successful admission receipt may also include the DID signature of the school's educational office system so that the couple may prove to others that the school indeed passed their children's admission application.
By applying the scheme, the cooperation of a plurality of government office platforms can be realized, under the premise of ensuring safety and reliability, citizens are not required to obtain paper certification documents, and the work efficiency is obviously improved.
In one embodiment, the government affairs result can be used for uploading the certificate. Specifically, in the block chain and decentralized identity based government affairs processing system, the government affairs office platform is further configured to: after a government affair processing result carrying a decentralized identity signature of the government affair office platform is generated, the government affair processing result is sent to the block chain; the block chain is further configured to: and acquiring the government affair processing result sent by the government affair office platform, and storing the government affair processing result in a distributed account book of the block chain.
In another illustrated embodiment, the government affairs processing results stored in the blockchain can be further arranged into a government affairs processing archive; specifically, the system for government affairs processing based on blockchains and decentralized identities may further include a digital identity archive platform docked to the blockchains, configured to group the government affair processing results stored in the distributed ledger of the blockchains according to the decentralized identities of the citizens, and generate government affair processing archives corresponding to the decentralized identities of the citizens according to the government affair processing results in each group. Business information handled by citizens is stored in the block chain, and people and object portrayal of the citizens is enriched. The relevant departments can create a complete digital identity profile for the citizen according to the information on the chain, and the profile can be updated in real time along with the social activities of the citizen. After the scheme is realized, the system is convenient for related departments to carry out tracing management according to personnel, and is also beneficial for citizens to supervise government affair treatment of the related departments.
Continuing to take the example that the floating population couples bring children to the city for learning, after the business of entering learning is successfully transacted, the digital identity archive platform can screen out the government affair processing results related to the couple according to the DID and arrange the government affair processing results into government affair processing archives; when the previous government affairs processing result needs to be presented later, the couple can be called by the DID identity.
The above description is directed to all embodiments of the block chain and decentralized identity based government affairs processing system. As can be seen from the foregoing embodiments, on the one hand, in the government affair processing system, decentralized identities of citizens and government affair office platforms are managed and verified by block chains, and since the block chains are distributed systems based on a cryptographic principle and composed of a plurality of nodes, the distributed systems are difficult to attack and tamper, and therefore, compared with a traditional government affair hall, the security of the government affair processing system can be improved. On the other hand, in the process that the citizen requests the government affair office platform to perform government affair processing by using the client, the citizen and the government affair office platform use the corresponding decentralized identity to perform signature verification, so that the information sent by the citizen and the government affair office platform cannot be repudiated, and the transparency of the government affair processing system can be improved by the scheme.
