Description

Technical Field

[0001] This application relates to the field of digital certificate technology, specifically to a digital certificate authentication method, terminal, system, and device for business cards. Background Technology

[0002] Traditional business cards, company brochures, event invitations, and promotional posters all display content through flat graphics and text. People can obtain relevant information through this two-dimensional information. For example, with existing ordinary business cards, after the information is designed, it is printed at a business card printing shop. Regardless of whether the information on the card is accurate, the printing shop will arrange for printing. When arranging the content of the business card, it is simply a matter of arranging some explanatory text on the card. This type of business card has the following problems: it is impossible to verify whether the holder and the owner of the business card are the same person. People often cannot be completely sure that the person holding the business card is the person described on the card. Even if the person holding the business card is the owner, it is impossible to verify the accuracy of the owner's information on the business card directly.

[0003] Therefore, how to solve the problem of the lack of security and reliability of information recorded in 2D graphic texts, and how to protect the rights and interests of owners of 2D graphic text information or recipients of content obtained from 2D graphic text information, are urgent technical problems that need to be solved. Summary of the Invention

[0004] The purpose of this application is to solve the technical problem that the information displayed on existing flat business cards lacks security and reliability. To this end, this application provides a digital certificate authentication method, terminal, system and device for business cards.

[0005] To address the aforementioned technical issues, this application provides a digital certificate authentication method for business cards. This method is applied to the company's corresponding user terminal, which is connected to a cloud-based public information platform.

[0006] Digital certificate authentication methods include:

[0007] The pedestrian terminal generates a digital certificate application based on the company registration information, and after being authenticated by the first certificate signer, signs the digital certificate application with the first time stamp and sends it to the cloud publicity platform for verification. The cloud publicity platform verifies the information of the first certificate signer and publishes it after the verification is passed.

[0008] The actor's terminal plans the business card information and limits the scope of rights based on the publicly announced application and registration digital certificate to form the actor's business card digital certificate. After being certified by the first certificate signer, the actor's business card digital certificate is signed with the second time stamp and sent to the cloud publicity platform for verification. After the verification is passed, it is publicized.

[0009] The perpetrator activates the digital certificate of their business card on their terminal and publishes it through a cloud-based public information platform;

[0010] The actor's terminal generates an invitation link for the executor's business card authentication digital certificate based on the publicized actor's business card digital certificate, and publishes it through the cloud public platform so that the executor's terminal can apply for the executor's business card digital certificate based on the invitation link;

[0011] The actor's terminal receives the digital certificate of the executor's business card sent by the executor's terminal through the cloud-based publicity platform. After confirming that the business card information and scope of rights of the executor's business card digital certificate are correct and after being certified by the first certificate signer, the executor's terminal is authorized to activate the digital certificate of the executor's business card and send it to the cloud-based publicity platform for verification and publicity. This allows the executor's terminal to activate the digital certificate of the executor's business card and, after verification through the cloud-based publicity platform, to be publicized. This confirms that the executor's terminal has the right to edit the business card information and completes the digital certificate authentication of the business card.

[0012] Preferably, the business card information includes text and image content, with the text content including fixed text and editable text, and the image content including the company logo.

[0013] Preferably, the steps for activating the executor's business card digital certificate on the authorized executor's terminal also include:

[0014] The actor's terminal authorizes the executor's terminal so that the executor's terminal can modify the business card information or customize the editable part of the business card information.

[0015] Preferably, the executor terminal includes a first executor terminal and a second executor terminal, with the first executor terminal managing the second executor terminal.

[0016] Preferably, the steps for verifying the information of the first certificate signatory by the cloud-based public disclosure platform include:

[0017] The actor's terminal stores the information of the first certificate signatory on the cloud-based public platform, forming a list of rights holders;

[0018] The actor's terminal sends the application for registration of digital certificate to the cloud publicity platform. The cloud publicity platform obtains the ID and public key corresponding to the actor's terminal based on the application for registration of digital certificate, and verifies it with the information of the first certificate signer in the list of rights holders stored locally on the cloud publicity platform. If the information matches, the verification is passed, and the cloud publicity platform publishes the application for registration of digital certificate.

[0019] The information of the first certificate signer includes the company name, the actor's name, the actor's terminal ID, and the public key.

[0020] Preferably, the invitation link for the digital certificate of the execution business card authentication, the digital certificate of the actor's business card, and the digital certificate of the executor's business card are in the form of hyperlinks or QR codes.

[0021] Another embodiment of the present invention provides a digital certificate authentication method for business cards. The digital certificate authentication method is applied to the executor terminal corresponding to the company, and the executor terminal is connected to the cloud-based public information platform.

[0022] Digital certificate authentication methods include:

[0023] The executor terminal applies for an executor business card digital certificate based on the invitation link for executor business card authentication digital certificate published on the cloud publicity platform, and applies to the actor terminal to modify part of the business card information. After verification by the second certificate signer, the executor business card digital certificate is signed with a third time stamp and sent to the cloud publicity platform for verification and publicity.

[0024] After receiving the authorization information sent by the actor's terminal through the cloud publicity platform, the executor's terminal activates the digital certificate of the executor's business card, and after verification through the cloud publicity platform, it is publicized to confirm that the executor's terminal has the right to edit the business card information and complete the digital certificate authentication of the business card;

[0025] Among them, the invitation link for the digital certificate of the executor's business card is formed by the actor's terminal based on the digital certificate of the actor's business card, and the digital certificate of the actor's business card is formed by the actor's terminal based on the application and registration of the digital certificate, which limits the rights and interests of the text content and image content of the business card information;

[0026] The information of the second certificate signer includes the company name, the executor's name, the ID of the executor's terminal, and the public key.

[0027] Another embodiment of the present invention provides a human terminal, comprising:

[0028] Processor, adapted to implement instructions; and

[0029] A computer storage medium suitable for storing multiple instructions, which are adapted to be loaded and executed by a processor to perform the steps of digital certificate authentication for a business card as described above.

[0030] Another embodiment of the present invention provides an executor terminal, comprising:

[0031] Processor, adapted to implement instructions; and

[0032] A computer storage medium suitable for storing multiple instructions, which are adapted to be loaded and executed by a processor to implement the aforementioned steps of digital certificate authentication for the business card.

[0033] Another embodiment of the present invention provides a business card digital certificate authentication system, the system comprising: a person terminal as described above, an executor terminal as described above, and a cloud-based public display platform for verifying and publicizing the application for registration of digital certificates, the person's business card digital certificate, and the executor's business card digital certificate;

[0034] The cloud-based public disclosure platform is connected to both the actor's terminal and the executor's terminal.

[0035] Another embodiment of the present invention provides a device in which a plurality of instructions are stored, the instructions being adapted to be loaded and executed by a processor to perform the steps of digital certificate authentication for a business card as described above.

[0036] This invention discloses a digital certificate authentication method, terminal, system, and device for business cards. After completing company registration through the actor's terminal, the actor plans and limits the rights and interests of the business card information, generates and activates a digital certificate for the actor's business card, and then affixes a QR code formed from the digital certificate to the business card. More personal information of the actor can be obtained through the QR code. This personal information is verified and publicized through a cloud-based platform and has the characteristic of being tamper-proof, ensuring the security and reliability of the business card information. The executor's terminal applies for an executor's business card digital certificate based on the invitation link generated by the actor's terminal. After obtaining authorization from the actor's terminal, the executor's business card digital certificate is activated, and a QR code formed from the executor's business card digital certificate is affixed to the physical business card. The recipient of the business card can obtain employee information that the executor has no right to modify through the QR code, gaining a deeper understanding of the employee's current position information. This invention limits the rights of company managers to the information on their subordinates' business cards. Employees must apply to their managers for authorization to modify or customize the information on their business cards, provided they have authorization. Modifications are only allowed on the editable portions of the information; employees only have the right to read it and cannot modify the rest. This ensures data security and reliability, preventing business card holders from tampering with employee information to defraud recipients. This not only solves the problem of insecure and unreliable business card information but also prevents infringement on the rights of the true business card owner, the company, or the recipient.

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Through the detailed description of the embodiments, a more in-depth and specific understanding can be gained of the technical means and effects adopted by this application to achieve its intended purpose. However, the accompanying drawings are for reference and illustration only and are not intended to limit this application.

[0052] Example 1

[0053] The method of this invention is based on the principle of digital certificate technology, which perfectly combines digital certificates and business card issuance to ensure that the data is tamper-proof and permanently valid. Under the decentralized architecture of digital certificates, the security of employee identity and company identity data is guaranteed, preventing criminals from impersonating business cards to commit fraud, infringing on the legitimate interests of the real business card owner or recipient, and causing the company to suffer property or reputational losses.

[0054] A digital certificate, also known as a public key certificate or identity certificate, is an electronic document that proves the ownership of a public key. Typically, a digital certificate includes the public key, the public key owner's identification information, and the digital signature of the issuing entity verifying the certificate's content. Authentication digital certificates build upon digital certificates by adding applicant information to the authentication business card, making them suitable for the field of printed and graphic products. The cloud-based public disclosure platform adopts a non-discriminatory disclosure mechanism, following a path of tamper-proof disclosure of rights and interests. It is a shared database where stored data or information possesses characteristics such as "unforgeable," "fully traceable," "traceable," "open and transparent," and "collectively maintained." Based on these characteristics, digital certificate technology lays a solid foundation of "trust" and creates a reliable "cooperation" mechanism.

[0055] This invention encrypts critical data on business cards during the application process. First, the cardholder encrypts the information using their corresponding key. Then, after verification by the certificate signer, the information is encrypted a second time using their corresponding key. Each encryption step involves publicly displaying the digital certificate on a cloud platform, ensuring data openness and transparency, thus preventing data tampering. Company managers have limited rights to subordinates' business card information. Authorization is required for specific sections of the card information; only after authorization can the manager modify or customize the information. Modifications are limited to editable sections; the remaining sections can only be viewed. The digital certificate is converted into a physical QR code and affixed to the business card. The recipient scans the QR code using an electronic device to access the cardholder's current employee information. This employee information can only be modified by company managers or administrative departments, ensuring data security and reliability. The cardholder cannot tamper with employee information to defraud the recipient. This not only solves the problem of insecure and unreliable business card information but also prevents infringement upon the rights of the true cardholder, the company, or the recipient.

[0056] The business card of the present invention can be replaced with other products containing graphic information, such as company brochures, event invitations, and promotional posters. By authenticating these products with digital certificates, recipients of the graphic information products can obtain secure and reliable data by scanning the QR code on the page.

[0057] This invention provides a digital certificate authentication method for business cards, such as... Figure 1 As shown, Figure 1 This is a flowchart illustrating an embodiment of the digital certificate authentication method for business cards according to the present invention. The digital certificate authentication method includes:

[0058] Step S101: The pedestrian, as the terminal, generates a digital certificate application based on the company registration information. After being authenticated by the first certificate signer, the application digital certificate is signed with the first time stamp and sent to the cloud publicity platform for verification. The cloud publicity platform verifies the information of the first certificate signer and publishes it after verification.

[0059] The actor is the company's legal representative or an assistant to the legal representative. The actor's terminal is the terminal device used by the actor to authenticate business cards, such as a smartphone, tablet, or laptop. The executor is a manager of a department within the company or an employee of the company. The executor's terminal is the terminal device held by the executor, such as a smartphone, tablet, or laptop.

[0060] The actor's terminal has a link propagation program installed. The executor's terminal triggers a start command through the executor's account, which then initiates the link propagation program's corresponding link, allowing interaction with the actor's terminal. The link propagation program can be installed on other terminals besides the actor's terminal; no restrictions are placed here. The cloud-based public disclosure platform communicates with both the actor's terminal and the executor's terminal.

[0061] An actor registers a company through their terminal and applies for a digital certificate based on the company registration information. If the actor is an assistant to the company's legal representative, they need to send the digital certificate to the first certificate signer for authentication. The first certificate signer verifies the company information and rights in the digital certificate and, upon confirmation, signs the certificate with their private key, indicating that the content of the digital certificate is correct. The first certificate signer, being the company's legal representative, can authorize the assistant to perform certain tasks; these tasks require confirmation from the company's legal representative to take effect. The digital certificate includes the actor's terminal ID, public key, company information, the scope of the actor's rights, and the first certificate signer's information, including the company name, the actor's name, the actor's terminal ID, and the public key. After the digital certificate is verified by the first certificate signer, they sign it with the actor's terminal private key, and the actor's terminal signs it with a first time stamp, sending it to a cloud-based public platform for verification. The first time stamp includes the time and location information of the actor's terminal signing. The user terminal stores the information of the first certificate signer on a cloud-based public platform, forming a list of rights holders. Upon receiving the application for a digital certificate, the cloud-based public platform obtains the user terminal's corresponding ID and public key, and verifies them against the first certificate signer's information stored locally on the cloud-based public platform. If the information matches, the verification is successful. If the verification is successful, it indicates that the application for a digital certificate has been authenticated by the first certificate signer, the application for a digital certificate has not been tampered with, and is reliable. The cloud-based public platform then publishes the application for a digital certificate. Once the application for a digital certificate has been verified, it means that the user terminal has completed company registration. The application for a digital certificate can take various forms, such as hyperlinks and QR codes. This invention uses a QR code as an example. After the user terminal completes the verification of the application for a digital certificate, it prints the application for a digital certificate to form a QR code digital certificate and publishes the QR code on the cloud-based public platform. Users can scan the QR code to obtain the content of the application for a digital certificate.

[0062] If the verification fails, the cloud-based public disclosure platform will return the application for registration digital certificate to the user's terminal and inform the user that the verification failed and the application for registration digital certificate is suspected of being tampered with. The user is requested to resubmit the correct application for registration digital certificate; otherwise, the application will not be publicized.

[0063] Step S102: The actor's terminal plans the business card information and limits the scope of rights based on the publicly announced application and registration digital certificate to form the actor's business card digital certificate. After being certified by the first certificate signer, the actor's business card digital certificate is signed with the second time stamp and sent to the cloud publicity platform for verification. After the verification is passed, it is publicized.

[0064] Step S103: The actor's terminal activates the digital certificate of the actor's business card and publicizes it through the cloud publicity platform.

[0065] After registering a company through a third-party terminal, the perpetrator creates a personal business card for the company's legal representative. Using the publicly disclosed digital certificate application on the terminal, the perpetrator plans and limits the scope of rights associated with the business card information. This information includes text and images, such as... Figure 2 As shown, Figure 2This is a business card structure according to an embodiment of the present invention. The text content includes fixed text and editable text. Fixed text includes company name, job title, company address, and company information. The fixed text is consistent with the company's business registration information; if the company's business registration information changes, the fixed text will also be modified accordingly. Editable text includes information such as name, mobile phone number, and email address. The editable text is synchronized based on the business card holder's real information. When company employees apply for business cards, they can fill in their personal information under the fixed text business card template, or customize their personal information. Alternatively, the user's terminal can complete the employee's personal information. Image content includes the company logo and a passport photo. Generally, the company logo is unchangeable, and the passport photo is the business card holder's passport photo. After the user plans the content of the business card information and defines the rights and interests of each item, a digital certificate for the user's business card is generated and sent to the first certificate signer. The first certificate signer confirms the information in the digital certificate. If the confirmation is correct, the first certificate signer signs the digital certificate with their private key and returns it to the user's terminal. The user's terminal signs the digital certificate with a second spatiotemporal stamp, which includes the time and location information of the user's terminal signing. The user's terminal sends the digital certificate of their business card to a cloud-based public platform for verification. Upon receiving the digital certificate, the cloud-based public platform obtains the user's terminal ID and public key, and verifies them against the information of the first certificate signer in the rights holder list stored locally on the platform. If the information matches, the verification is successful. If the verification is successful, it indicates that the digital certificate of the user's business card has been authenticated by the first certificate signer, has not been tampered with, and is reliable. The cloud-based public platform then publishes the digital certificate of the user's business card. Once the digital certificate of the user's business card is verified, it means that the user's terminal has completed the rights restrictions on the content planning of the business card information. The business card holder has clear restrictions on modifying the content of the business card; the holder can only modify or customize the content that they have the authority to modify. The digital certificate of the user's business card can take various forms, such as hyperlinks and QR codes. This invention uses a QR code as an example. After the user's terminal completes the verification of the digital certificate of the user's business card, it prints the certificate to form a QR code digital certificate and publishes the QR code through the cloud-based public platform. The user can scan the QR code to obtain the content of the digital certificate of the user's business card.

[0066] If the verification fails, the cloud-based public disclosure platform will return the digital certificate of the infringer's business card to the infringer's terminal and inform the infringer that the verification failed and the digital certificate of the infringer's business card is suspected of being tampered with. The infringer should resubmit the correct digital certificate of the infringer's business card; otherwise, the information will not be disclosed.

[0067] After the user's terminal completes the creation of the user's business card digital certificate, it activates the certificate and affixes a QR code generated from it to the physical business card. The activated certificate is then publicly displayed on a cloud-based platform. Upon receiving the business card, the recipient can scan the QR code using electronic settings to access the user's information and company information. As the company's legal representative, the user's image represents the company, acting as its promoter. Therefore, the recipient not only obtains the user's personal information from the business card but also accesses the company's website to learn more about its development and business.

[0068] Step S104: The actor's terminal generates an invitation link for the executor's business card authentication digital certificate based on the publicized actor's business card digital certificate, and publishes it through the cloud public platform so that the executor's terminal can apply for the executor's business card digital certificate based on the invitation link.

[0069] Step S105: The actor's terminal receives the digital certificate of the executor's business card sent by the executor's terminal through the cloud publicity platform, confirms that the business card information and scope of rights of the executor's business card digital certificate are correct, and after being certified by the first certificate signer, authorizes the executor's terminal to activate the digital certificate of the executor's business card and send it to the cloud publicity platform for verification and publicity, so that the executor's terminal can activate the digital certificate of the executor's business card and publicize it after verification through the cloud publicity platform, thus confirming that the executor's terminal has the right to edit the business card information and completing the digital certificate authentication of the business card.

[0070] After viewing the digital certificate of the actor's business card published on the cloud-based publicity platform through the actor's terminal, an invitation link for the digital certificate of the executor's business card authentication is generated. The actor triggers a start command for the link propagation program corresponding to the actor's terminal, which then initiates the link propagation program to spread the invitation link of the digital certificate of the executor's business card authentication to the executor's terminal. After viewing the invitation link of the digital certificate of the executor's business card authentication through the executor's terminal, the executor applies for the digital certificate of the executor's business card. That is, after obtaining the invitation link of the digital certificate of the executor's business card authentication, the executor fills in the personal information of the executor's business card authentication digital certificate invitation link according to their own employee information, such as the corresponding job level, name, mobile phone number, email address, and personal ID photo. After completing the information, the executor confirms the information to generate the digital certificate of the executor's business card, and signs it with the private key corresponding to the executor's terminal before sending it to the cloud-based publicity platform.

[0071] After receiving the digital certificate of the executor's business card, the cloud-based disclosure platform verifies whether the ID and public key corresponding to the executor's terminal are consistent with the ID in the digital certificate of the executor's business card. If the verification is successful, the platform will disclose the certificate and send it to the executor's terminal. If the verification is successful, it means that the digital certificate was issued by the corresponding executor and the business card information applied for by the executor is consistent with the information stored by the company. If the verification fails, it means that the digital certificate of the executor's business card may have been submitted by someone impersonating the executor. The cloud-based disclosure platform will return the digital certificate of the executor's business card to the executor's terminal and inform the executor to submit the correct application certificate.

[0072] The actor's terminal receives the digital certificate of the executor's business card sent by the executor's terminal through the cloud-based public disclosure platform. It obtains the relevant content of the digital certificate, confirms the accuracy of the business card information and scope of rights, and after verification by the first certificate signer, authorizes the executor's terminal to activate the digital certificate and send it to the cloud-based public disclosure platform for verification. After verifying the correctness of the actor's terminal's ID and public key, the cloud-based public disclosure platform publishes the executor's digital certificate to the executor's terminal.

[0073] After receiving the digital certificate of the executor's business card published on the cloud-based disclosure platform, the executor's terminal activates the digital certificate and affixes it as a QR code to the physical business card. The activated digital certificate is then published on the cloud-based disclosure platform. Upon receiving the business card, the recipient can access the holder's company and position information based on the displayed information. To find out if the holder is currently employed, has received significant honors or contributions, or has been promoted, the recipient can scan the QR code on the business card using an electronic device. This will take them to the company's employee information section, where they can access the holder's latest position information. If the holder has left the company, the employee information section will display a warning message such as "This employee has left the company and is no longer an employee of this company." If the business card holder is still employed and has achieved a promotion or other outstanding performance, the employee information section will display information such as the business card holder's career path and significant achievements. This allows the recipient to gain a deeper understanding of the business card holder. Furthermore, the business card holder cannot modify the content in the employee information section, increasing the reliability and security of the business card information and preventing criminals from using the business card to commit fraud.

[0074] Preferably, the invitation link for the digital certificate used to authenticate the business card is in the form of a hyperlink or a QR code. All digital certificates of this invention can be converted into physical QR codes. These QR codes can be affixed to a physical business card, allowing the recipient to verify the cardholder's personal information via the QR code. Based on the information presented by the digital certificate, the recipient can quickly obtain secure and reliable business card information, preventing fraudulent activities such as misuse of the business card.

[0075] In this embodiment, after the actor completes company registration through the actor's terminal, they plan and define the rights and interests of their business card information, generate and activate a digital certificate for the actor's business card, and then attach a QR code formed from the digital certificate to the business card. More personal information of the actor can be obtained through the QR code. This personal information is verified and publicized through a cloud-based platform and is tamper-proof, ensuring the security and reliability of the business card information. The executor's terminal applies for an executor's business card digital certificate based on the invitation link generated by the actor's terminal. After obtaining authorization from the actor's terminal, the executor's business card digital certificate is activated, and a QR code formed from the executor's business card digital certificate is attached to the physical business card. The recipient of the business card can obtain employee information that the executor has no right to modify through the QR code, gaining a deeper understanding of the employee's current position information. This invention limits the rights of company managers to the information on their subordinates' business cards. Employees must apply to their managers for authorization to modify or customize the information on their business cards, provided they have authorization. Modifications are only allowed on the editable portions of the information; employees only have the right to read it and cannot modify the rest. This ensures data security and reliability, preventing business card holders from tampering with employee information to defraud recipients. This not only solves the problem of insecure and unreliable business card information but also prevents infringement on the rights of the true business card owner, the company, or the recipient.

[0076] Example 2

[0077] Please refer to Figures 3-4 , Figures 3-4 This is another embodiment of the digital certificate authentication method of the present invention. The method includes:

[0078] 201: The actor's terminal starts the initialization program.

[0079] 202: Create an account for the actor, complete personal information, register a company, and apply for a digital certificate.

[0080] The actor terminal, cloud-based publicity platform, and executor terminal in this embodiment are the same as in Embodiment 1, and will not be described again here.

[0081] The user's terminal is equipped with an initialization program. The user's terminal initiates the initialization program via an initialization command. This program creates a user account based on the user's needs, completes the user's relevant information based on the account, registers a company, generates a digital certificate application, and submits the digital certificate application to the cloud-based public platform. The user's terminal automatically completes the company registration process through the initialization program. The digital certificate application includes the user's terminal ID and public key, and is signed with the user's terminal's private key to ensure secure transmission.

[0082] 203: Application for registration of digital certificate based on actor's account.

[0083] 204: The first certificate signer signs the application for registration of a digital certificate with their private key.

[0084] 205: Sign the application for registration of a digital certificate with the first time stamp.

[0085] 206: Submit an application to register a digital certificate.

[0086] After viewing the digital certificate application through their terminal, the user triggers a startup command on the corresponding initialization program. This command initiates the initialization program, which then propagates the digital certificate application to the cloud-based public disclosure platform. The cloud-based platform verifies the user's terminal's ID and public key before publishing the application, and the user's terminal receives the digital certificate application. If the cloud-based platform fails to verify the application, it returns the digital certificate application to the user's account, informing them of the verification failure and requesting them to modify and resubmit.

[0087] After receiving the digital certificate application from the cloud-based public platform, the actor's terminal retrieves the information within the digital certificate. Upon confirming the information is correct, it signs the digital certificate using its private key, indicating that the actor has verified the information. Following confirmation, the actor's terminal sends the proposed company digital certificate to the first certificate signer, who then re-verifies the information. The first certificate signer checks the company information and rights associated with the digital certificate. Upon confirmation, the first certificate signer signs the digital certificate using their private key, indicating the certificate's content is correct. The digital certificate includes the actor's terminal ID, public key, company information, the scope of the actor's rights, and the first certificate signer's information, including the company name, the actor's name, the actor's terminal ID, and the public key. After the first certificate signer verifies the digital certificate, they sign it using their private key, and the actor's terminal signs it with a first time stamp before sending it to the cloud-based public platform for verification. The first time stamp includes the time and location information of the signatory's terminal. If a problem occurs during the digital certificate registration application, the first time stamp can be used to trace all records during the certificate's generation period. All information about the actor's terminal is recorded in the first time stamp, allowing for quick location of the problem and identification of the responsible party. The actor's terminal stores the information of the signatory of the first certificate on a cloud-based public platform, forming a list of rights holders.

[0088] 207: Verify the information of the signatory of the first certificate.

[0089] 208: Public announcement of applications for digital certificate registration.

[0090] After receiving the application for a digital certificate, the cloud-based public disclosure platform obtains the ID and public key corresponding to the user's terminal and verifies them against the information of the first certificate signatory in the rights holder list stored locally on the cloud platform. If the information matches, the verification is successful. If the verification is successful, it indicates that the digital certificate application has been authenticated by the first certificate signatory, has not been tampered with, and is reliable. The cloud platform then publishes the digital certificate application. Once the digital certificate application is verified, it means that the user's terminal has completed company registration. The digital certificate application can take various forms, such as hyperlinks and QR codes. This invention uses a QR code as an example. After the user's terminal completes the verification of the digital certificate application, it prints the digital certificate application to form a QR code digital certificate and publishes the QR code through the cloud platform. Users can scan the QR code to obtain the content of the digital certificate application.

[0091] If the verification fails, the cloud-based public disclosure platform will return the application for registration digital certificate to the user's terminal and inform the user that the verification failed and the application for registration digital certificate is suspected of being tampered with. The user is requested to resubmit the correct application for registration digital certificate; otherwise, the application will not be publicized.

[0092] 209: The actor's terminal plans the business card information.

[0093] 210: The rights of the actor's terminal to the information on the business card are limited.

[0094] 211: Generate a digital certificate for the actor's business card based on the business card information.

[0095] 212: The actor's terminal verifies the business card information.

[0096] 213: Submit the verified digital certificate of the actor's business card to the first certificate signatory for confirmation.

[0097] 214: The first certificate signer signs the actor's business card digital certificate with their private key.

[0098] 215: Sign the digital certificate of the actor's business card with the second time stamp.

[0099] 216: Submit the digital certificate of the actor's business card.

[0100] After registering a company through the actor's terminal, the actor can create business cards for all employees of the company, including the legal representative, department heads, and ordinary employees. The creation of the legal representative's business card differs from that of some department heads and ordinary employees. When creating a personal business card for the company's legal representative, the actor uses the actor's terminal to plan and limit the scope of rights for the business card information based on the publicly disclosed digital certificate application. The business card information includes text and image content, and is the same as in Example 1, so it will not be repeated here. That is, except for the content involving business registration information, which cannot be customized, the rest of the content on the legal representative's business card can be modified according to actual needs. The rights of department heads' business card information are limited by the actor's terminal. After limiting the rights of the business card information, the actor's terminal generates a business card template. The template consists of two parts: a fixed, uneditable part and an editable part, which can be filled in by the actor's terminal or by the actor's terminal and then reviewed by the actor's terminal. Once approved, the business card information is created. The actor verifies the digital certificate of the actor's business card through the actor's terminal, and submits the verified digital certificate of the actor's business card to the first certificate signatory for confirmation.

[0101] The first certificate signer verifies the information in the digital certificate for the actor's business card. Once confirmed, the first certificate signer signs the digital certificate using their private key and returns it to the actor's terminal. The actor's terminal then signs the digital certificate using a second time stamp, which includes the time and location information of the signing. If a problem arises with the digital certificate, the second time stamp can be used to trace all records during its generation. All information about the actor's terminal is recorded in the second time stamp, allowing for rapid location of the problem and identification of the responsible party.

[0102] The actor's terminal sends the actor's business card digital certificate to the cloud-based public platform for verification.

[0103] 217: Verify the information of the signatory of the first certificate.

[0104] 218: Publicize the business card and digital certificate of the perpetrator.

[0105] After receiving the digital certificate of the actor's business card, the cloud-based disclosure platform obtains the ID and public key corresponding to the actor's terminal and verifies them against the information of the first certificate signer in the list of rights holders stored locally on the cloud-based disclosure platform. If the information matches, the verification is successful. If the verification is successful, it means that the digital certificate of the actor's business card has been certified by the first certificate signer, the digital certificate of the actor's business card has not been tampered with, and is reliable. The cloud-based disclosure platform then publishes the digital certificate of the actor's business card. When the digital certificate of the actor's business card is verified, it means that the actor's terminal has completed the rights and interests restrictions of the content planning of the business card information. The business card holder has clear restrictions on modifying the content of the business card. The business card holder can only modify or customize the part of the business card that they have permission to modify. The digital certificate of the actor's business card can take various forms, such as hyperlinks and QR codes. This invention takes the form of a QR code as an example. After the actor's terminal completes the verification of the digital certificate of the actor's business card, it prints the digital certificate of the actor's business card to form a QR code digital certificate, and publishes the QR code through the cloud-based disclosure platform. By scanning the QR code, the content of the digital certificate of the actor's business card can be obtained.

[0106] If the verification fails, the cloud-based public disclosure platform will return the digital certificate of the infringer's business card to the infringer's terminal and inform the infringer that the verification failed and the digital certificate of the infringer's business card is suspected of being tampered with. The infringer should resubmit the correct digital certificate of the infringer's business card; otherwise, the information will not be disclosed.

[0107] 219: The actor's terminal activates the actor's business card digital certificate.

[0108] 220: Verify the information of the first certificate signatory.

[0109] 221: Publicize the business card and digital certificate of the perpetrator.

[0110] After the user's terminal completes the creation of the user's business card digital certificate, it activates the certificate and sends it to the cloud-based public disclosure platform. Upon receiving the activated certificate, the platform obtains the user's terminal ID and public key and verifies them against the information of the first certificate signer in the rights holder list stored locally on the platform. If the information matches, the verification is successful. If the verification passes, it indicates that the user's business card digital certificate has been authenticated by the first certificate signer, has not been tampered with, and is reliable. The cloud-based public disclosure platform then publishes the certificate. Once the digital certificate is verified, it means the user's terminal has completed activation, and the certificate holder can create physical business cards for distribution. The digital certificate can take various forms, such as hyperlinks and QR codes. Taking a QR code as an example, after the actor's terminal completes the verification of the actor's business card digital certificate, the actor's business card digital certificate is printed to form a QR code digital certificate, and the QR code is publicized through a cloud public platform. By scanning the QR code with the terminal, the content of the actor's business card digital certificate can be obtained.

[0111] If the verification fails, the cloud-based public disclosure platform will return the digital certificate of the infringer's business card to the infringer's terminal and inform the infringer that the verification failed and the digital certificate of the infringer's business card is suspected of being tampered with. The infringer should resubmit the correct digital certificate of the infringer's business card; otherwise, the information will not be disclosed.

[0112] The perpetrator affixes a QR code generated from the digital certificate of their business card to the physical business card. After receiving the business card, the recipient can scan the QR code using electronic settings to obtain relevant information about the perpetrator and promotional materials about the company. As the legal representative of the company, the perpetrator's image represents the company's image and is equivalent to the company's promoter. Therefore, the recipient can not only obtain the perpetrator's personal information from the business card, but also access the company's website to learn more about the company's development and business information.

[0113] 222: Invitation link for executor's business card authentication digital certificate generated based on the actor's business card digital certificate.

[0114] 223: Start the link propagation process.

[0115] 224: Invitation link for digital certificate authentication of the dissemination executor's business card.

[0116] The actor's terminal generates an invitation link for the executor's business card authentication digital certificate through the actor's business card digital certificate published on the cloud-based public platform. The link can be in the form of a hyperlink or a QR code; this embodiment uses a QR code as an example. After the actor's terminal generates the invitation link for the executor's business card authentication digital certificate, a start command is triggered on the link propagation program corresponding to the actor's terminal. This start command initiates the link propagation program to spread the invitation link for the executor's business card authentication digital certificate to the actor's terminal.

[0117] 225: Create an executor account and apply for an executor business card digital certificate based on the executor business card authentication digital certificate invitation link.

[0118] 226: The executor fills in personal information to generate an executor's business card digital certificate.

[0119] 227: Submit the executor's business card digital certificate to the second certificate signatory for confirmation.

[0120] 228: The executor's business card digital certificate is signed by the second certificate signer with their private key.

[0121] 229: Sign the executor's business card digital certificate with a third time stamp.

[0122] 230: Submit the executor's business card and digital certificate.

[0123] The executor terminal creates an executor account. After receiving an invitation link for the executor's business card authentication digital certificate from the actor terminal through the executor account, the executor terminal obtains the actor's business card digital certificate information, fills in personal information according to the business card template, and forms the executor's business card digital certificate. In this embodiment, the executor terminal includes a first executor terminal and a second executor terminal. The first executor terminal is responsible for managing the second executor terminal; that is, the first executor is a partial manager, and the second executor is a partial manager responsible for managing subordinate employees. Each company has multiple departments, each managed by a manager. The manager's subordinates can be ordinary employees or team leaders. The first executor applies for their business card from the actor terminal, while the second executor applies for their business card from the first executor terminal. The application methods are largely the same, and the process of the second executor terminal applying for a business card from the first executor terminal will not be repeated here. Please refer to the method of the first executor terminal applying for a business card from the actor terminal. The difference is that the second executor terminal enters the business card application page through the executor's business card authentication digital certificate invitation link, and after completing the personal information, forms the executor's business card digital certificate. This digital certificate needs to be submitted to the second certificate signer for verification. The second certificate signatory is actually a responsible person, namely the department manager. The department manager needs to verify the digital certificate of the executor's business card submitted by the second executor's terminal, and check whether the content of the digital certificate of the executor's business card is the same as the real information of the second executor. Only after the verification by the second certificate signatory is passed can the second executor's terminal proceed to the next step. If the verification by the second certificate signatory fails, the second certificate signatory will return the digital certificate of the executor's business card to the second executor's terminal, notifying the second executor to modify the certificate. The information of the second certificate signatory includes the company name, the name of the executor, the executor's job level and permissions, and the ID and public key corresponding to the executor's terminal.

[0124] After the second certificate signer confirms the accuracy of the information in the executor's business card digital certificate, the second certificate signer signs the executor's business card digital certificate with their private key and returns it to the second executor's terminal. Upon receiving the executor's business card digital certificate, the second executor's terminal signs it using a third time stamp. This third time stamp includes the location information of the time the executor's terminal signed the certificate. If a problem arises with the executor's business card digital certificate, all records during its generation can be traced based on the third time stamp. All information of the executor's terminal is recorded in the third time stamp, allowing for rapid location of the problem and identification of the responsible party.

[0125] The executor's terminal sends the executor's business card digital certificate to the cloud-based public platform for verification.

[0126] 231: Verify the information of the signatory of the second certificate.

[0127] 232: Publicize the executor's business card and digital certificate.

[0128] 233: Submit the executor's business card and digital certificate.

[0129] After receiving the digital certificate of the executor's business card, the cloud-based disclosure platform obtains the ID and public key corresponding to the executor's terminal and verifies them against the information of the second certificate signer in the rights holder list stored locally on the cloud-based disclosure platform. If the information matches, the verification is successful. If the verification is successful, it means that the digital certificate of the executor's business card has been authenticated by the second certificate signer, the digital certificate has not been tampered with, and is reliable. The cloud-based disclosure platform then publishes the digital certificate of the executor's business card. Once the digital certificate of the executor's business card is verified, it means that the executor's terminal has completed the business card application. The content of the business card is filled in according to the permissions granted by the executor's terminal, clearly defining the scope of the executor's permissions. The digital certificate of the executor's business card can take various forms, such as hyperlinks and QR codes. This invention uses a QR code as an example. After the executor's terminal completes the verification of the digital certificate of the executor's business card, it prints the digital certificate of the executor's business card to form a QR code digital certificate, and publishes the QR code through the cloud-based disclosure platform. The content of the digital certificate of the executor's business card is obtained by scanning the QR code with the terminal.

[0130] If the verification fails, the cloud-based public disclosure platform will return the digital certificate of the executor's business card to the executor's terminal and inform the executor's terminal that the verification failed and the digital certificate of the executor's business card is suspected of being tampered with. The executor should resubmit the correct digital certificate of the executor's business card; otherwise, the information will not be disclosed.

[0131] 234: The actor's terminal verifies the business card information of the executor's business card digital certificate.

[0132] 235: Submit the verified executor's business card digital certificate to the first certificate signatory for confirmation.

[0133] 236: The executor's business card digital certificate is signed by the first certificate signer with their private key.

[0134] 237: Authorize the executor's terminal to activate the executor's business card digital certificate.

[0135] 238: Submit authorization information.

[0136] After receiving the digital certificate of the executor's business card from the cloud-based public disclosure platform, the actor's terminal obtains the employee information of the executor who applied for the certificate. It then verifies this information against the information stored in the system. In this embodiment, if the executor is the first executor, the digital certificate of the executor's business card, after being reviewed and approved by the actor's terminal, is submitted to the first certificate signer for confirmation. Once the first certificate signer confirms that the certificate is correct, they sign the digital certificate of the executor's business card using their private key, and the actor's terminal authorizes the executor's terminal to activate the digital certificate. If the executor is the second executor, the digital certificate of the executor's business card, after being reviewed and approved by the actor's terminal, authorizes the executor's terminal to activate the digital certificate. The actor's terminal then submits the authorization information to the cloud-based public disclosure platform.

[0137] 239: Verify the ID and public key corresponding to the actor's terminal.

[0138] 240: Publicize the executor's business card and digital certificate.

[0139] 241: Submit authorization information.

[0140] After receiving the authorization information sent by the actor's terminal, the cloud-based public disclosure platform verifies the ID and public key corresponding to the actor's terminal. Once the verification is successful, it sends the authorization information to the executor's terminal.

[0141] 242: Activate the executor's digital certificate on the executor's terminal.

[0142] 243: Submit the activated executor's business card digital certificate.

[0143] 239: Verify the ID and public key corresponding to the executor's terminal.

[0144] 240: Publicize the executor's business card and digital certificate.

[0145] After the executor's terminal completes the creation of the executor's business card digital certificate, it activates the certificate and sends it to the cloud-based public disclosure platform. Upon receiving the activated certificate, the platform obtains the executor's terminal's ID and public key and verifies them against the corresponding information in the rights holder list stored locally on the platform. If the information matches, the verification is successful. If the verification passes, it indicates that the executor's business card digital certificate has been authenticated by the first or second certificate signatory, has not been tampered with, and is reliable. The platform then publishes the certificate. Once the certificate is verified, the executor's terminal has completed activation, and the certificate holder can create physical business cards for distribution. The executor's business card digital certificate can take various forms, such as hyperlinks and QR codes. Taking a QR code as an example, after the executor's terminal completes the verification of the executor's business card digital certificate, the executor's business card digital certificate is printed to form a QR code digital certificate, and the QR code is publicized through a cloud public platform. By scanning the QR code with the terminal, the content of the executor's business card digital certificate can be obtained.

[0146] If the verification fails, the cloud-based public disclosure platform will return the digital certificate of the executor's business card to the executor's terminal and inform the executor's terminal that the verification failed and the digital certificate of the executor's business card is suspected of being tampered with. The executor should resubmit the correct digital certificate of the executor's business card; otherwise, the information will not be disclosed.

[0147] The executor's terminal generates a QR code from the executor's business card digital certificate and affixes it to the physical business card. The activated digital certificate is then publicly displayed on a cloud-based platform. Upon receiving the business card, the recipient can access the holder's company and position information based on the displayed details. To find information such as current employment status, significant achievements, and promotions, the recipient can scan the QR code to access the company's employee information section. This section displays the holder's latest job information. If the holder has left the company, a warning message such as "This employee has left and is no longer an employee of this company" will appear. If the holder is still employed and has achieved promotions or other outstanding performance, the employee information section will display their career path and significant achievements, providing the recipient with a deeper understanding of the holder. Furthermore, the holder cannot modify the information in the employee information section, increasing the reliability and security of the business card information and preventing fraudulent activities.

[0148] In this embodiment, the method first initiates an initialization process through the actor's terminal to form an actor's account. The actor's terminal completes company registration through this account and the cloud-based public disclosure platform. Based on the company registration information, a digital certificate for the actor's business card is generated, activated, and then publicized on the cloud-based public disclosure platform. After verification and public disclosure on the cloud-based public disclosure platform, the actor's business card information has the characteristic of being tamper-proof, making the actor's business card secure and reliable. The executor's terminal applies for an executor's business card digital certificate based on the invitation link generated by the actor's terminal. After obtaining authorization from the actor's terminal, the executor's business card digital certificate is activated, and a QR code of the executor's business card digital certificate is affixed to the physical business card. The permissions of the business card information are pre-defined to ensure the data security of the business card information. Utilizing the immutability of the digital certificate, not only is the problem of the lack of security and reliability of business card information solved, but also the rights and interests of the true business card owner, company, or business card recipient are prevented from being infringed.
