Description

Block chain-based paper-electricity integrated certificate query method and system and storage medium

Technical Field

The invention relates to the technical field of internet information, in particular to a method, a system and a storage medium for inquiring a paper-electricity integrated certificate based on a block chain.

Background

The traditional anti-counterfeiting verification of paper certificates, official documents, certificates, vouchers and the like mainly comprises the step of comparing and identifying with a reserved seal by naked eyes to obtain a verification result of subjective identification. With the progress of scientific technology, the clone stamp can be completely copied by modern technologies such as high-definition scanning and laser engraving, and the copied stamp and the seal stamp stamped by the stamp cannot be identified by the traditional human eye comparison method.

In addition, in the use process of a large number of seal stamps stamped by certificates, official documents, certificates and certificates (hereinafter referred to as certificates), people who receive the certificates often do not reserve the seal stamp of the certificate, so that the authenticity of the certificates cannot be identified by comparison, people can only judge whether the seal stamp on the certificate is in compliance by experience and intuition to perform anti-counterfeiting verification, the verification result is unreliable, and the problem of 'three false' (false seals, false official documents and false certificates) is easily caused.

In order to solve the problem of 'three false', the prior art uses an electronic signature or an electronic seal instead of a paper certificate and a physical seal. For electronic seals, in the prior art, before issuing a certificate, information (text or image) of the certificate is generally issued on an official website of an issuing organization, so that people can inquire and verify the certificate from the official website according to information such as a letter number on a paper certificate, and the mode really has a certain anti-counterfeiting effect. However, this way of query validation is not convenient enough.

Therefore, how to realize authoritative, reliable, convenient and quick query and verification of the certificate in the using process is an urgent problem to be solved.

Detailed Description

The invention will be further explained and explained with reference to the drawings and the embodiments in the description. The step numbers in the embodiments of the present invention are set for convenience of illustration only, the order between the steps is not limited at all, and the execution order of each step in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.

As shown in fig. 1, the overall framework of the system of the present embodiment is: a voucher credit platform dominated and supervised by the government is built by adopting a alliance corporate chain technology, a main operator serves as a deposit and certificate transmission pipeline, and a credit alliance chain (hereinafter, referred to as a voucher chain) with judicial endorsement is formed by a plurality of authoritative organizations such as government departments, judicial departments, financial institutions or internet platforms and the like and participates in accounting together and stores electronic voucher data together.

The certificate chain carries out full-flow certificate storage on the electronic certificate based on the block chain, carries out multi-party maintenance on credible supervision and supervision of data by combining the block chain system, carries out supervision and monitoring in multiple links of data acquisition, data flow and data certificate storage, realizes regular monitoring through automatic rules, effectively enhances the credibility of data supervision work, and avoids centralized single-party risks.

Meanwhile, the certificate chain also takes electronic certificate storage as a core application scene, and based on an underlying network platform of the alliance public chain technology, internet application products and services such as trusted electronic certificate storage, convenient and fast checking, trusted resource publicity, personal data space, judicial evidence discharge, credit evaluation and the like are created.

Referring to fig. 2, based on the general architecture of the credential chain shown in fig. 2, the credential chain platform of the present embodiment has the following functions:

1. and (3) certificate storage: by combining the block chain technology and applying the characteristics of non-tampering, traceability and the like, the content and the forming time of the electronic data are cured in real time, the trueness and the justness of the certificate data are ensured, and the legal proof efficacy is given to the electronic data file. The universal code electronic seal is first used by each functional department of government and public service institution, when the certificate, official document, document and certificate are issued, the seal with machine-readable interface and digital enciphered signature is added, and the seal is photographed and scanned and stored in block chain, and if the information content is required to be enciphered, it can be enciphered or not.

2. Convenient examination: when the integrated paper and electricity voucher is used and a user needs to verify the authenticity of the voucher, the dAPP of the mobile terminal or the smart phone can be used for scanning the seal on the paper voucher to obtain an access key hidden on the seal, uploading the certificate chain, checking the validity, authenticity and integrity of the certificate signing and issuing, and obtaining original image-text information of the certificate when the certificate is stored at a second level. And the electronic certificates can be safely and conveniently shared to a third party through encrypted transmission by utilizing dAPP. The credible, safe and convenient certificate checking and sharing mode forms a favorable condition for thoroughly eradicating the social psoriasis problem of the certificates of 'three fakes' (false seals, false documents and false certificates) under the condition of almost one hand of mobile phone at present, assists in the national supervision of the certificates and the credits, and strengthens the credit construction.

3. Instant messaging: the block chain evidence-saving platform-based instant messaging dAPP (hereinafter referred to as dAPP) is different from other commonly used instant messaging tools (such as WeChat, QQ, Pan-Bao-Wang and the like), the identities of participating objects are credible, chat records can be selected to be uploaded to the certificate chain platform for evidence saving as digital evidence, disputes are avoided, and quick arbitration and approval can be performed when disputes occur. dAPP is an application layer interface of a certificate chain platform, and is a link and key for connecting a person and the platform. Information resources, data application and operation of the voucher chain platform are all completed through the voucher chain platform, and the voucher chain platform has the function similar to a resource browser. Meanwhile, dAPP is a manager of a user personal account and a data space, provides various practical functions and becomes a necessary tool for a user to feel at will. dAPP can also scan and check various certificates with ten thousand phase codes to identify true or false, and is a sharp tool for preventing and eliminating 'three false' (false official seal, false official document and false certificate). The dAPP can safely share various resources in the credential chain platform among dAPP users.

4. And (3) trusted resource disclosure: because the identity of an individual or an organization on a block chain certificate storage platform is authentic and credible by relying on the supervision class node of a government authority, based on the characteristics of repudiation prevention, tampering prevention and traceability of a block chain technology, the speaking content data of the individual or the organization (including a government department) on the certificate chain platform is linked and locked and cannot be changed, and the identity is permanently stored in the certificate chain platform, needs to be responsible for the own behavior and receives the time inspection. Thus, various information published on the blockchain evidence platform can be standardized, including information such as public notices, announcements, promotions, commitments, products, services, and the like. Because of the block chain technology, the right of the information resource distributed here is clear and the responsibility is clear. A "clean" internet can be implemented. The network platform based on the certificate chain is an internet space with controllable ownership and order, and has profound significance.

5. Personal data space: the natural people who rely on the natural people bank and have the identity authenticated can build personal main body data by themselves and quote and store the data accumulated in government affair service platforms, organizations and the like. On the basis of a certificate chain platform, the control right of personal data is owned by a person, but not owned by a centralized mechanism, and the legal data asset property of natural people is fully realized. In order to improve the interest and participation of the masses, the data of personal self-establishment of common certificates, certificates and the like is supported. For example, under the circumstance that the public cares about personal health at present, personal health files (issued by various medical and physical examination organizations) are particularly pushed out, health data (including medical cases and electronic images) cared about by people can be controllably, safely and conveniently used, and the services of reassurance, safety, convenience, efficiency and economy can be provided in the aspects of medical insurance reimbursement, insurance claim payment, remote medical treatment, personal health guidance and the like. The personal data space stores authenticated information, personal digital identity and submitted data, is a real and accurate data asset of a person, and provides important data support for constructing a personal contribution model, measuring and calculating the personal contribution, constructing a social credit system and the like. In the traditional big data application process, the problems of unclear data, low data application efficiency, nonstandard data service operation, substandard data security protection and the like generally exist. The establishment of the personal data space of the certificate chain platform can effectively solve the problems, really realize the high-efficiency management of personal data assets, the strict prevention and control of core data leakage and the sharing of data in various forms, and has the functions of promoting the accuracy, controllability and equalization of social public services.

6. And (3) judicial evidence obtaining: the voucher chain platform can not only issue a corresponding security certificate for each data record by butting a judicial appraisal center, but also obtain a judicial appraisal opinion book which accords with the national electronic data court scientific appraisal general method according to the requirement, so that the data evidence has the judicial effectiveness.

7. And (3) credit evaluation: the credit evaluation system is constructed by integrating the credit information of government and third-party credit investigation institutions through data exchange and sharing by using a block chain technology. In a credit evaluation system of a certificate chain platform, each piece of data is authenticated, private and real, so that the problems of data privacy disclosure, unknown ownership and the like in the past big data credit investigation are solved. The certificate chain does not combine data in various traditional concept big data credit, but every data on the platform is really existed, and every user has a corresponding natural person or legal person in reality. The identity on the platform is a truthful result, including certificates issued by authorities or identity information verified by government related authorities. As a 'trusted machine', the block chain technology reconstructs a traditional credit system, trust is manufactured by building mutual verification of bridges among distributed mass data, and credit is developed, so that the value exchange process is smoother, and the exchange cost is reduced. Meanwhile, the decentralized distributed account book technology of the block chain ensures the reality, safety and unchangeability of data. In a novel credit evaluation system constructed by using a block chain technology, all credit information is tied and chained on the internet and is interconnected and intercommunicated, so that a credible data ecology is provided for scenes such as government affair service, social management, commercial application and the like, and a better bottom layer support is provided for rapid development of emerging industries such as internet of things, artificial intelligence, mobile internet and the like.

The embodiment provides a paper and electricity integrated certificate block chain certificate storage method, which specifically comprises the following steps:

the certificate chain is a leading service platform based on a block chain technology and taking generation and convenient inspection of a paper-electricity integrated certificate as a core, aims to eliminate and prevent the phenomenon of three fakes (false official seal, false official document and false certificate) of the certificate, protects the user data asset ownership and information safety sharing, and creates a clean and credit interconnected network space.

Firstly, dividing the certificate into four privacy states:

red: the certificate can not be disclosed, namely the full text of the certificate can not be viewed, and only the hash value of the certificate can be seen.

Yellow: the disclosed certificate can be authorized, the authorized principal can see all information of the certificate, and the unauthorized principal can only see the hash value of the certificate. Only the issuer of the credential has the authorization rights of the credential.

Blue color: the voucher which can be viewed by scanning the ten thousand photo seal stamps can directly see the complete information of the voucher.

Green: the document can be opened and the complete information of the document can be seen directly or by scanning and reading the ten thousand-photo seal.

Secondly, uploading the non-government approved electronic seal or digital certificate user:

the certificate uploaded by a non-government approved electronic seal or digital certificate user (hereinafter referred to as a non-electronic seal user, including individuals and legal organizations) for the first time is green, namely, the certificate can be disclosed, but the certificate is in an untrusted state and does not meet the uplink condition. The uploading party needs to find the unit which has the certificate at that time in the platform, so that the uploading party can verify the authenticity of the certificate, the certificate can be marked as a trusted certificate state only when the verification is passed, and a non-homogeneous token is generated in a chain way; after the non-electronic seal user uploads the certificate, if the corresponding issuing unit of the certificate is not found, the issuing unit of the certificate can be invited to enter the platform through the self invitation code.

The non-homogeneous token in this embodiment means: each token is unique, possesses unique attributes, has a minimum unit of 1, and is not sub-divisible. Non-homogeneities are widespread in life, for example: artwork, pets, handicrafts, customized articles, etc., and may even be used to mark students in schools, medical and sick in hospitals, etc. The application scenes are very wide.

And a homogeneous token refers to: each token is identical in nature, interchangeable, subdivided into N shares, and similar to real life currencies, can fulfill all currency roles.

Thirdly, uploading the electronic seal or digital certificate approved by the government by a user:

the user of the electronic seal or the digital certificate (hereinafter referred to as the user of the electronic seal) approved by the government can upload the existing certificate of stock or add new certificate. Whether the certificate is stored or newly added, as long as the certificate is uploaded by an electronic seal user, the certificate is directly identified as a credible certificate and linked into a non-homogeneous token. The certificate is in yellow authority when initially uploaded, namely, only an electronic seal user, a certificate beneficiary, a principal or an authorized person who presents the certificate can see a complete report; subsequently, the user of the electronic seal can change the certificate into a red state, a green state or a blue state according to the requirement of the user or the requirement of the certificate entrustor or the beneficiary. In this embodiment: the blue state is set, and the certificate needs to be a paper-electronic integrated certificate, and can be verified by scanning a ten thousand photo signature.

Fourthly, uploading the electronic seal user encrypted by ten thousand phase codes approved by the government:

the universal code encryption electronic seal user (hereinafter referred to as universal code seal user) approved by the government adopts a special universal code block chain encryption electronic seal technology, so that when a paper-electricity integrated certificate is manufactured during creating the certificate, a high-performance block chain security encryption anti-counterfeiting tamper-proof technology is adopted, the certificate can be uploaded and directly identified as a credible certificate, and the certificate is linked to form a non-homogeneous token. The certificate is blue in authority when initially uploaded, namely, a complete certificate can be seen only by a user who has a ten thousand codes seal with the certificate and the ten thousand codes on the certificate stamp which is scanned by a smart phone, and other people cannot view complete information of the certificate from a certificate chain platform.

The embodiment also provides a trusted certificate query method, which specifically comprises the following steps:

the certificate of the certificate chain platform is based on the block chain technology, and the whole network is unique and credible, so that the certificate chain platform has high commercial value. The user can conveniently and quickly inquire the credible certificate on the platform, know the authenticity of the certificate and the credit condition of a certificate issuing unit, and realize the national supervision. The specific functions include:

firstly, scanning:

the electronic certificate is associated with the ten-thousand-photo signature on the paper certificate, a user can directly scan the ten-thousand-photo signature through a scanning function of the platform dAPP to obtain the associated electronic certificate and the information of a certificate issuing unit. The certificate associated with the ten-thousand-photo seal is consistent with the privacy state of the certificate on a certificate chain platform, namely when only the hash value of the certificate can be checked on the platform, the hash value of the ten-thousand-photo seal is scanned; when the full text of the certificate can be seen on the platform, the full text can also be seen after scanning.

Second, checking one for checking:

the user can use the inquiry function of the platform, and all the main bodies (legal organization and individuals) authenticated and disclosed by the platform can obtain the qualification information of the uplink of the main bodies and the credentials of the uplink (different privacy states show different) by inputting the name of the main body. If the full-text of the yellow privacy state certificate is to be checked, an authorizer is required to be found to apply for authorized checking. The query function can help the user to know the authentic and trusted subject information and the trusted quality assurance of the certificate.

Thirdly, a trusted data supervision entrance:

the voucher chain leaves a data interface for government agencies that can review quality data and do corresponding regulatory work and make policies. First, government agencies can obtain more authentic and trusted principal credit data, and urge the principal to standardize credentials. And secondly, government agencies can conveniently carry out certificate spot check and supervision on the main body in the platform at any time. After the subsequent voucher process is linked, the whole-course data of the voucher is public and transparent, and a supervision mechanism can monitor the quality of the voucher issuing main body in real time. The voucher chain is based on a platform voucher database, a visual full-platform data monitoring system is developed for the government, and a monitoring organization can conveniently know the conditions and the trends of the whole industry.

Fourthly, working steps:

the voucher linking platform using the block linking technology for voucher linking mainly comprises three steps: subject docketing, credential generation, and uplink retrospection. Through the three steps, the issuing body can complete the whole process of certificate authentication and trusts the credit guarantee to the certificate user and the related interest parties.

The working logic of the credential chain platform mentioned in this embodiment is as follows:

1. recording a main body:

the main body records as a preparation stage before uplink, the certification main body is allowed to access the certificate chain platform after certificate credit confirmation specified by the system, and all registration data and credit information of the main body become the certificate on the chain of identity authentication. The voucher, information, data and the like uploaded by the main body are associated with the main body and displayed after the system audits the voucher, the information, the data and the like.

2. And (3) generating a certificate:

after the certification main body passes the registration authentication, the credit grade, the associated certificate and the like are written into the certificate chain, the data are guaranteed not to be falsified by the block chain technology, the basic information of the certification main body is formed, the certification main body needs to further perfect the related data, and a foundation is laid for the next uplink tracing: the core business process comprises the following steps:

the certificate issuing main body uploads the certificate; the platform service node performs compliance validity detection on the certificate, uploads the certificate and generates a class erc721 token (non-homogeneous token); and logging in the certificate chain platform by the user to inquire the certificate.

3. Tracing uplink:

the tracing cochain is a cochain operation stage, the certificate issuing main body writes certificate data into the certificate responsibility main body, and the related supervision organization provides trust endorsement, so that the core content of the certificate credit tracing is formed, and the certificate beneficiary can be used as a trusting party to complete the association of the certificate credit data (including the certificate and the credit tracing) and the certificate interest related affairs or real objects, including the work of certificate inquiry code application, other certificate universal code association, data uploading and the like.

Fifth, platform role

The participation role of the certificate chain platform is mainly all the interest relevant parties on the certificate chain, including social public, individuals, organizations, government departments, enterprises, consumers, product production or sales factories (enterprises), service providers and government supervision organizations, and for easy understanding, the participation role is roughly divided into four categories according to the functions and functions: "supervisor", "publisher", "reviewer", "server".

1. A "supervisor":

the government department is a supervision manager of the platform, and can acquire platform data, spot check the certificates issued by the certificate issuer and trace the credit thereof. The government initiates and leads the establishment of city integrity alliance, and jointly establishes an industry standard, service industry development and leading construction of a certificate chain platform. The supervisor is responsible for supervising and managing the participants of the certificate chain platform, authenticating the identities of the publisher and the server, managing the authority, and supervising and managing the behaviors of the publishers and the servers on the platform. The device corresponding to the "supervisor" is a "supervisory node" device.

2. The "publisher":

whether the certificate is a personal or legal organization (including government organs and enterprises and public institutions), the certificate can be applied to a platform supervisor to become a certificate issuer when the certificate chain admission condition is met (for example, a personal issuer meets personal real-name authentication, a legal organization meets identity authentication, and electronic seals or digital certificates and supporting equipment approved by a government regulatory department are purchased). A personal "publisher" can publish personal credentials to the platform using a mobile terminal or smartphone. Corporate organizations "publishers" can publish credentials using dedicated credential publishing devices (both desktop and portable, purchased by "publishers"). The issuer who owns the desktop issuing equipment (the corporate organization) can become the service provider of the certificate chain (namely, the service provider of the certificate chain platform for packaging chain-up service, commonly called 'mining' earning points). The device corresponding to the "publisher" is a palm top computer (PDA) terminal or workstation.

3. "inspector":

whether the organization is a personal organization or a legal organization, the organization is naturally a 'checker', and can download and install a decentralized application program (dAPP) from a government official network or a certificate chain official network, and an upper certificate chain platform can 'check' the certificate information on the chain, and can 'scan' the ten thousand-code seal of the certificate in a paper form or an electronic image form to quickly check the certificate information. If the 'inspector' wants to participate in the information feedback and credit tracing of the certificate, the 'issuer' is required to apply for the certificate. The device corresponding to the "verifier" is a digital device that can connect to the internet and run a certificate chain decentralized application (dAPP), which are commonly used as a smart phone, a Personal Digital Assistant (PDA), a tablet computer (PAD), and a computer.

4. "server":

no matter the organization is a person or a legal person, the device which meets the service requirement of the voucher chain platform node is purchased and connected with the Internet, and the application is made to the platform supervisor, and the platform supervisor can become the platform server after the approval is obtained. Because the credential chain is a government-initiated and dominant alliance public chain, it is generally the case that the need to join a "server" team first joins a "credit alliance". Most of the cases, the platform technology developers of the certificate chain, the telecom operators providing network services, the data cloud service providers and the government affairs service data centers are the main force of platform 'service providers'. The device corresponding to the "server" is a "service node" device.

Sixthly, platform main equipment

1. The "client":

a service interface for the "publisher" to write blocks of credential data, to query credentials, and to submit blocks of data or query instructions to the "access server".

2. "supervision Server":

the system is used by a supervisor and is responsible for the identity confirmation and authority management of participants of the certificate chain platform.

3. "access server":

and receiving a data block or a query instruction from the client, and sending a data block or query instruction request to the distributed verification server.

4. "distributed authentication server":

by the consensus system, the data blocks are subjected to consensus verification, and when the block period is up, the verification server writes the verified data block set into the block chain.

5. "blockchain system":

and supporting data storage for the verification server to write verified data into a corresponding block chain.

The specific steps of the paper-electricity integrated certificate query method of the invention are described in detail as follows:

the query means that a user sets certain searching and seeking conditions and finds out what the user wants at a certain place or places.

The inquiry of the paper-electricity integrated certificate refers to that an inspector searches an original electronic certificate corresponding to the certificate on a certificate chain platform according to a universal code seal impression on the certificate, and the inquiry aims to verify whether the certificate exists on the certificate chain platform, whether the certificate is real and complete and whether the content is consistent. The paper-electricity integrated certificate forms a closed-loop system from generation, release and storage in a block chain to inquiry and sharing in the using process, and the purpose is achieved conditionally.

The method for inquiring the paper-electricity integrated certificate based on the block chain has the characteristics of convenience, rapidness, safety and credibility.

The method comprises the following specific contents:

firstly, generation of a paper-electricity integrated certificate:

the integrated paper and electronic certificate is produced by means of universal code technology, electronic seal technology and block chain technology, and has the electronic certificate identical to the paper certificate in content and enciphered and released to the block chain platform.

Checking the paper-electricity integrated certificate:

the seal positions of the paper and electricity integrated certificate are all covered with universal photo seal stamps. The digital signature contains the decryption key of the (secret) electronic certificate on the platform for extracting the certificate chain. As long as the identification of the ten-thousand-photo code on the paper or electronic certificate is clear, the content of the ten-thousand-photo code can be read by using a scanning function of the mobile phone dAPP, the secret certificate data is downloaded in an access certificate chain, and the original certificate information is obtained by decrypting the secret electronic certificate data by using the mobile phone dAPP, so that the safety, the reality and the credibility are ensured.

The checker scans the identification of the universal code on the certificate by using an intelligent terminal (a mobile phone or a palm computer with the functions of photographing and surfing the internet), reads the key value of the universal code on the identification of the certificate, extracts a corresponding secret certificate data block from a certificate chain platform by using index information in the key value of the universal code, decrypts by using a decryption key in the key value of the universal code to obtain an original electronic certificate, obtains an electronic signature of the certificate, and compares the consistency of the contents with the checker to obtain the judgment of the authenticity of the checked certificate.

Thirdly, the inquiry of the paper-electricity integrated certificate is convenient and safe:

1. the paper-electricity integrated certificate is stored on a certificate chain supported by a block chain technology, so that the certificate is real and credible.

2. The integrated paper and electronic voucher is stored in an encrypted state on the voucher chain, and staff of a service node on the voucher chain cannot see the content of the voucher, so that the safety is ensured; even if a worker wants to violently break the content of the decrypted voucher, the time consumed is long, and the worker cannot be worth after breaking the content, so that the safety is guaranteed.

3. Scanning a universal photo code on a certificate signature through an intelligent terminal (a mobile phone or a palm computer with the functions of photographing and surfing the internet), extracting corresponding secret certificate data on a certificate chain, downloading the secret certificate data to the intelligent terminal, wherein the data is data in an encrypted state in the transmission process, and the transmission safety can be ensured; in actual use, data transmission is encrypted by adopting an SSL (secure socket layer) protocol, so that the transmission safety is further ensured; the intelligent terminal decrypts the downloaded secret certificate data by using the key in the universal code key value to obtain the plaintext of the original certificate, so that the certificate is convenient, quick, safe, reliable and credible to inquire.

The invention relates to a method for inquiring a paper-electricity integrated certificate, which comprises the following steps of:

the invention provides different implementation steps according to the presentation mode of the integrated paper-electronic voucher.

Referring to fig. 3, a paper voucher of the paper-electricity integrated voucher is held by the 'inspector':

step 1: the checker judges whether the paper voucher held by hand has a ten-thousand-phase code seal impression, if so, the next step is executed, otherwise, the inquiry is stopped and quit.

It should be noted that the ten-thousand-phase code mentioned in the embodiment is substantially a code including key values and images, and those skilled in the art can designate the code by different names when designing the code, such as the eight diagrams code, the dot matrix code, etc., which are all within the protection scope of the ten-thousand-phase code of the present invention.

Step 2: the checker operates the intelligent terminal (the intelligent mobile phone or the PDA with the image acquisition function and the like which can be connected with the Internet) to start the decentralized application software (dAPP) of the certificate chain platform to align the seal of the paper certificate to be scanned.

And 3, step 3: if the dAPP successfully identifies the identification of the ten-thousand-photo code signature to obtain a key value of the ten-thousand-photo code, carrying out the next step; otherwise, the "reviewer" may choose to return to "step 2" or may choose to directly abandon, fail the query, abort the exit.

And 4, step 4: the intelligent terminal obtains a service interface of the certificate chain platform, inquires the access authority of the terminal from the access server according to the service interface, if the inquiry and verification authority of the terminal is effective, the next step is carried out, otherwise, the inquiry is failed, and the quitting is stopped.

And 5, step 5: and the intelligent terminal takes the index parameter in the ten-thousand-phase code key value as the parameter of the query certificate and sends the parameter to the access server.

And 6, step 6: and the access server extracts a corresponding secret certificate data block from a distributed database of the certificate chain according to the index parameter of the received inquiry certificate.

And 7, step 7: and the access server forwards the secret certificate data block to the intelligent terminal.

And 8, step 8: the intelligent terminal decrypts the secret certificate data block by using a decryption key in the universal code key value to obtain the original content of the certificate, namely an electronic paper format (PDF) certificate file subjected to electronic signature.

Step 9: the intelligent terminal verifies and signs the electronic paper format (PDF) certificate file, the result is displayed on a screen (a certificate issuer, issuing time, integrity verification and the like), and the original electronic certificate content is displayed at the same time.

Step 10: the examiner compares whether the paper certificate held by the opponent is consistent with the content displayed on the screen of the intelligent terminal, and if so, the next step is carried out; otherwise, judging the paper voucher to be a false voucher and quitting.

And 11, step 11: the "reviewer" may choose to save the credentials at the intelligent terminal or not.

Step 12: if the electronic certificate corresponding to the paper certificate is selected to be stored on the intelligent terminal, the storage forms are three: the identification method comprises the steps of printing a picture of a ten-thousand-photo code of a paper certificate, a key value of the ten-thousand-photo code and a certificate file in an electronic paper format (PDF). If the inquired electronic certificate is not stored, the inquiry is successful and quitting is performed.

Step 13: if a space-saving storage mode is adopted, the ten-thousand-phase code key values (including index parameters, decryption keys and the like of the inquiry certificates) of the electronic certificates are stored on the intelligent terminal, and the inquiry is successful and the terminal quits.

Step 14: if the storage mode convenient for offline (offline and non-networking) reference is adopted, the electronic paper format (PDF) certificate file is stored on the intelligent terminal, and the query is successful and quit.

Step 15: if the certificate photo needs to be stored for a specific purpose, the certificate is stored as a photo file on the intelligent terminal (the resolution setting can ensure that the requirement of re-identification of the ten-thousand-photo seal can be met later), and the inquiry is successful and the exit is finished.

Two, "the inspector" has saved the paper-electricity unification voucher in the intelligent terminal:

step 1: the checker operates an intelligent terminal (an intelligent mobile phone or a PDA and the like which can be connected with the Internet and has the image acquisition function) to start decentralized application software (dAPP) of the certificate chain platform and check the stored integrated paper and electricity certificates.

Step 2: if the stored certificate photo is a voucher photo, checking whether the photo album code seal is clear, if so, performing the step 5, otherwise, failing to inquire and stopping quitting.

And 3, step 3: if the picture of the code seal of the voucher is stored, checking whether the code seal of the voucher is clear, if so, performing the step 5, otherwise, failing to inquire and stopping quitting.

And 4, step 4: if the key value of the ten-thousand-phase code of the certificate (including the index parameter and the decryption key of the inquiry certificate) is stored, the step 7 is carried out, otherwise, the inquiry is failed, and the exit is stopped.

And 5, step 5: the checker manually operates the intelligent terminal to start the dAPP screen code scanning function, and manually operates to enable the ten-thousand-picture code seal on the screen to be at a proper position (the size and the center of the ten-thousand-picture code seal are at a proper position).

And 6, step 6: if the dAPP successfully identifies the identification of the ten-thousand-photo code signature to obtain a key value of the ten-thousand-photo code, carrying out the next step; otherwise, the "reviewer" may choose to return to "step 5" or may choose to directly abandon, fail the query, abort the exit.

And 7, step 7: the intelligent terminal obtains a service interface of the certificate chain platform, inquires the access authority of the terminal from the access server according to the service interface, if the inquiry and verification authority of the terminal is effective, the next step is carried out, otherwise, the inquiry is failed, and the quitting is stopped.

And 8, step 8: and the intelligent terminal takes the index parameter in the ten-thousand-phase code key value as the parameter of the query certificate and sends the parameter to the access server.

Step 9: and the access server extracts a corresponding secret certificate data block from a distributed database of the certificate chain according to the index parameter of the inquiry certificate.

Step 10: and the access server forwards the secret certificate data block to the intelligent terminal.

And 11, step 11: the intelligent terminal decrypts the secret certificate data block by using a decryption key in the universal code key value to obtain the original content of the certificate, namely an electronic paper format (PDF) certificate file subjected to electronic signature.

Step 12: the intelligent terminal verifies and signs the electronic paper format (PDF) certificate file, the result is displayed on a screen (a certificate issuer, issuing time, integrity verification and the like), and the original electronic certificate content is displayed at the same time.

Step 13: the 'inquirer' checks whether the certificate verification signature displayed on the screen of the intelligent terminal is normal or not, and if the certificate verification signature is normal and complete, the next step is carried out; otherwise, the certificate is judged to be a false certificate, the query is failed, and the exit is stopped.

Step 14: the "reviewer" may choose to restore the credential or not at the intelligent terminal.

Step 15: if the electronic certificate corresponding to the paper certificate is selected to be saved on the intelligent terminal again, the saving forms are three: the identification method comprises the steps of printing a picture of a ten-thousand-photo code of a paper certificate, a key value of the ten-thousand-photo code and a certificate file in an electronic paper format (PDF). If the inquired electronic certificate is not stored, the inquiry is successful and quitting is performed.

Step 16: if a space-saving storage mode is adopted, the ten-thousand-phase code key values (including index parameters, decryption keys and the like of the inquiry certificates) of the electronic certificates are stored on the intelligent terminal, and the inquiry is successful and the terminal quits.

Step 17: if the storage mode convenient for offline (offline and non-networking) reference is adopted, the electronic paper format (PDF) certificate file is stored on the intelligent terminal, and the query is successful and quit.

Step 18: if the certificate photo needs to be stored for a specific purpose, the certificate is stored as a photo file on the intelligent terminal (the resolution setting can ensure that the requirement of re-identification of the ten-thousand-photo seal can be met later), and the inquiry is successful and the exit is finished.
