Description

Technical Field

[0001] This invention relates to the fields of information security carriers, cloud server interaction and ownership confirmation methods, and particularly to a method for confirming and transmitting ownership of private information. Background Technology

[0002] In scenarios involving the transmission of private information, the demands for information security, traceability, physical verification, and ownership confirmation are becoming increasingly prominent. Existing information carriers and related technologies face numerous technical challenges and cannot meet the needs of practical applications. Specific shortcomings are as follows:

[0003] 1) The QR code is exposed and can be viewed by anyone, so there is no data confidentiality.

[0004] 2) The content is pre-set by the manufacturer when you scratch off the code, and there is no strict distinction or location of the sender and receiver; 3) The lack of a clear real-name ownership confirmation mechanism makes it impossible to determine the unique identity of the information sender, and the information cannot be traced after it has been tampered with or sent under a false name; 4) The confidentiality mechanism is singular, either allowing only public transmission or only strictly private transmission, unable to switch flexibly according to the scenario, and unable to determine whether the information has been opened in advance through the physical structure. 5) Information transmission is mostly one-way, and it is not possible to flexibly set the recipient's reply permissions to adapt to the interaction needs of different scenarios; 6) Pure software-based private transmission solutions lack physical carrier support, making it impossible to achieve long-term sealing and public mailing, and there is no physical verification structure.

[0005] Currently, there is no technical solution that can deeply integrate a two-layer physical carrier with a cloud server to clearly achieve unique correspondence between the two codes, real-name authentication, flexible verification, physical verification, and scalable interaction. Summary of the Invention

[0006] The purpose of this invention is to provide a method for confirming ownership and transmitting private information. This method offers high security and flexibility in the transmission of private information, and is suitable for scenarios such as resume submission, postcards, greeting cards, private messages between couples, last words of the elderly, and will sealing.

[0007] To achieve the above objectives, the present invention provides a method for confirming and transmitting ownership of private information. The manufacturer creates an identification information layer covered with a scratch-off coating on a carrier substrate to form an information carrier. After obtaining the information carrier, the sender scratches off the coating and scans the identification information layer on the carrier substrate using a mobile terminal to access the cloud server, where ownership is confirmed and private information is entered. The sender then hands the information carrier to the receiver, who scans the identification information layer on the carrier substrate using a mobile terminal to access the cloud server and view the private information entered by the sender.

[0008] As a further improvement of the present invention, the identification information layer scanned and identified by both the information sender and the information receiver using their respective mobile terminals is the same third identification information layer, which is covered with a third scratch-off coating.

[0009] As a further improvement of the present invention, the identification information layer includes a first identification information layer and a second identification information layer that are independent of each other, both of which are disposed on the same carrier substrate; after obtaining the information carrier, the information sender scratches off the first scratch-off coating covering the outside of the first identification information layer, scans and identifies the first identification information layer through a mobile terminal to enter the cloud server, and then confirms the rights and enters private information; the information sender hands the information carrier to the information receiver, and the information receiver scans and identifies the second identification information layer through a mobile terminal to enter the cloud server and view the private information entered by the information sender.

[0010] As a further improvement of the present invention, after the information sender hands the information carrier to the information receiver, the information receiver needs to first scratch off the second scratch-off coating covering the outside of the second identification information layer, and then scan the second identification information layer through a mobile terminal to enter the cloud server and view the private information entered by the information sender.

[0011] As a further improvement of the present invention, after the information sender, as the first person to scan the code, enters the cloud server for the first time by scanning the first identification information layer through the mobile terminal, he submits personal identity verification information to the cloud server. After the verification is passed, the cloud server automatically completes the real-name ownership confirmation of the information sender and uniquely binds the information sender's identity information, mobile phone number and the first identification information layer and the second identification information layer of the information carrier.

[0012] As a further improvement of the present invention, after the cloud server automatically completes the real-name ownership verification of the information sender, the information sender selects the mobile phone number of the preset information recipient in the cloud server, enters it into the cloud server and saves it; after the information recipient scans and identifies the second identification information layer to enter the cloud server, he / she needs to enter the preset mobile phone number and complete the verification of the cloud server. Only after the verification is passed can he / she view the private information entered by the information sender in the cloud server.

[0013] As a further improvement of the present invention, the information sender can independently set whether the information recipient has reply permission through the cloud server; when reply permission is enabled, the information recipient can submit reply content through the cloud server after viewing the information. The reply content is uniquely bound to the identification information layer of the information carrier and is associated and stored by the cloud server. The information sender can view it at any time; when reply permission is disabled, the information recipient can only view the information and cannot submit a reply.

[0014] As a further improvement of the present invention, the private information entered on the cloud server is encrypted and stored by the cloud server to achieve information solidification and evidence preservation.

[0015] As a further improvement of the present invention, the identification information layer is one or any combination of QR code, mini-program code or alphanumeric code; the recorded private information is one or any combination of text, image, video, audio, and document.

[0016] Beneficial effects Compared with the prior art, the advantages of the method for confirming and transmitting ownership of private information in this invention are: 1. Since the manufacturer only produces the information carrier, and the private information is entered by the sender A, and the identification information layer is generated and uniquely matched by the cloud server, forgery, substitution, and miscoding can be prevented at the source, significantly improving security. This solution uses a physical information carrier (such as a card, postcard, greeting card, resume card, will card, etc.) and mobile terminal identification. When the sender A first receives the information carrier, they can determine whether the information carrier has been used by checking if the scratch-off coating on the identification information layer is intact, thus improving the security of information transmission. After receiving the physical information carrier, the recipient B can choose to access the cloud server to view the private information in a sufficiently private environment by scanning the identification information with a mobile terminal. It is not easy for a third party to read the private information, especially when the identification information layer includes independent first and second identification information layers.

[0017] 2. When both the information sender A and the information receiver B use their respective mobile terminals to identify the same identification information layer, this identification information layer can be viewed by multiple different information receivers B.

[0018] 3. By setting a scratch-off coating, the sender and receiver can check whether the corresponding identification information layer has been used by a third party by scratching off the integrity of the coating before using the information carrier for the first time.

[0019] 4. Creatively achieve deep collaboration between physical information carriers and cloud servers, clarify the input and output logic of cloud servers, and add access restrictions for non-first scanners. That is, when non-owners of information carriers scan the first identification information layer, only blank content and corresponding prompts are displayed, further strengthening the uniqueness of ownership and information security. This solves the problems of ambiguous cloud server functions, weak feasibility, and insufficient ownership protection in existing solutions. At the same time, by pre-generating a unique correspondence between the two codes through the cloud server, the forgery and replacement of identification information are prevented from the source, thereby improving the security of information transmission.

[0020] 5. The sender's real name and ownership are confirmed, and the cloud server records the entire operation process, enabling full-process traceability of information transmission. This solves the problems of existing carriers being unable to determine the unique owner and information being untraceable after being tampered with.

[0021] 6. It can flexibly preset the identity verification mechanism of the information recipient, supports switching between public viewing and strictly private viewing modes, and adapts to different scenarios such as resume submission, private messages, and wills, with high flexibility.

[0022] 7. The second scratch-off coating serves as a physical verification structure, allowing for a direct assessment of whether information has been opened beforehand. Combined with encrypted storage on the cloud server, this forms a dual security guarantee of "physical verification + cloud encryption," enhancing the security of private information transmission.

[0023] 8. The sender can flexibly enable / disable the recipient's reply permission through the cloud server, enabling free switching between one-way private transmission and two-way interaction, adapting to more use cases.

[0024] 9. The information carriers are diverse in form and simple in structure. The cloud server has clear input and output logic, can be repeatedly implemented, is easy to industrialize and promote, and has a wide range of applications.

[0025] The invention will become clearer from the following description, taken in conjunction with the accompanying drawings, which are used to explain embodiments of the invention. Attached Figure Description

[0026] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0027] Figure 1 This is one of the schematic diagrams illustrating the usage status of the information carrier in Example 1; Figure 2 This is the second schematic diagram of the information carrier usage status in Example 1; Figure 3 This is the third schematic diagram of the information carrier usage status in Example 1; Figure 4 This is a flowchart of the method for confirming and transmitting ownership of private information in Example 1; Figure 5 This is a schematic diagram of the information carrier usage status in Example 2. Detailed Implementation

[0028] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0029] Example 1 Specific embodiments of the present invention are as follows: Figures 1 to 4 As shown, an information carrier C specifically designed for transmitting private information includes a carrier substrate 1. The carrier substrate 1 has an identification information layer covered with a scratch-off coating. The identification information layer allows information sender A to scan and identify the information using a mobile terminal to access a cloud server, confirm ownership, and enter private information. It also allows information receiver B to scan and identify the information using a mobile terminal to access the cloud server and view the private information entered by information sender A.

[0030] Private information entered on the cloud server is encrypted and stored by the cloud server, achieving information solidification and evidence preservation. The identification information layer is one or any combination of QR code, mini-program code, or alphanumeric encoding. The entered private information can be one or any combination of text, image, video, audio, or document.

[0031] In this embodiment, the identification information layer includes a first identification information layer 2 and a second identification information layer 4, both of which are disposed on the same carrier substrate 1. The first identification information layer 2 is used by the information sender A to scan and identify using a mobile terminal, and the second identification information layer 4 is used by the information receiver B to scan and identify using a mobile terminal. The scratch-off coating includes a first scratch-off coating 3 and a second scratch-off coating 5, both of which are independent. The first scratch-off coating 3 completely covers the first identification information layer 2, and the second scratch-off coating 5 completely covers the second identification information layer 4.

[0032] The identification information layer can be a QR code, a mini-program code, or a combination of alphanumeric codes. This information carrier C is suitable for scenarios such as resume submission, public circulation, postcards, greeting cards, private messages between lovers, last words of the elderly, and sealing of wills.

[0033] Cloud server input / output instructions: 1. Input process (various types of data / instructions received by the cloud server) 1) Pre-generated input: Before printing the information carrier C, the cloud server pre-generates first identification information, second identification information, and their unique one-to-one binding relationship data as initial input data, which is synchronously stored in the cloud server's encrypted database. The manufacturer prints the first identification information layer 2 and the second identification information layer 4 on the carrier substrate 1, and covers the surface of the first identification information layer 2 with a first scratch-off coating 3, and the surface of the second identification information layer 4 with a second scratch-off coating 5, thereby producing the information carrier C.

[0034] 2) Identity Verification Input: After obtaining the information carrier C through purchase, information sender A sees that the first scratch-off coating 3 on the outer side of the first identification information layer 2 on the carrier substrate 1 has not been scratched off, indicating that no one has scanned the first identification information layer 2 before. Information sender A scratches off the first scratch-off coating 3 covering the outer side of the first identification information layer 2 and scans the first identification information layer 2 using a mobile terminal (e.g., a mobile phone) to access the cloud server. The cloud server receives the scanning request sent by the mobile terminal and the mobile phone number entered by information sender A. The cloud server sends an SMS verification code, and information sender A submits the verification code to the cloud server. The cloud service completes the real-name ownership confirmation.

[0035] 3) Information entry: After ownership confirmation is completed, the cloud server receives the private information content (including text, pictures, videos, documents, etc.) uploaded by the information sender A through the mobile terminal, as well as the mobile phone number of the information recipient B set by the information sender A (optional) and the information recipient B's reply permission setting instructions.

[0036] 4) Recipient Input: Information sender A hands information carrier C to information recipient B. Recipient B checks the integrity of the second scratch-off coating 5 on the surface of the second identification information layer 4 to determine if it has been used by someone else before. Recipient B first scratches off the second scratch-off coating 5 covering the outside of the second identification information layer 4, then scans the second identification information layer 4 with a mobile terminal to access the cloud server. Recipient B can then view the private information uploaded by information sender A (if information sender A has not preset a recipient's mobile phone number). If information sender A has preset a recipient's mobile phone number, the cloud server receives a scanning request from the mobile terminal. Recipient B needs to enter their mobile phone number (if a recipient is preset) and the corresponding SMS verification code to complete identity verification before viewing the private information uploaded by information sender A. If information sender A has enabled reply permissions, the cloud server can receive replies submitted by information recipient B.

[0037] 5) Permission operation input: The message sender A can send permission enable / disable commands to the cloud server via mobile terminal, and the message recipient B can send commands to modify / delete the mobile phone number, etc.

[0038] 2. Output process (various data / instructions fed back from the cloud server to the terminal / user) 1) Verification feedback output: For the identity verification operation of the information sender and information receiver, the cloud server outputs the verification result (pass / fail) to the mobile terminal. When it fails, the reason for failure is output at the same time (such as incorrect verification code, mismatched mobile phone number, etc.). 2) Ownership Binding Output: After the message sender completes SMS verification, the cloud server outputs a success message for ownership confirmation to the mobile terminal, and simultaneously outputs the binding information (the binding relationship between the message sender's mobile phone number and the carrier's dual identification information). 3) Information viewing and output: After the information recipient completes identity verification (if required), the cloud server outputs encrypted and stored private information to the mobile terminal, supporting normal display of various formats such as text, images, and videos; 4) Operation feedback output: For operations such as setting permissions for the sender, entering information, and deleting information, the cloud server outputs success / failure prompts to the mobile terminal; for operations such as replying to the recipient, it outputs success / failure prompts for reply submission. 5) Traceability data output: The cloud server can output the entire process operation record of the carrier to the information sender (including the time of information sender's confirmation of rights, information entry time, information recipient's viewing time, reply content submission time, etc.), which can be used for ownership tracing and dispute verification; 6) Error Prompt Output: When an error occurs, such as scanning failure, mismatch of recognition information, expired verification code, or insufficient permissions, the cloud server outputs the corresponding error prompt to the mobile terminal to guide the user to complete the correct operation; in particular, when a person who is not the first person to scan the first recognition information layer scans the code, blank content and the prompt "Not the owner of the information carrier, cannot view and input information" are output.

[0039] 3. Input / output coordination logic The input and output operations of the cloud server are in one-to-one correspondence, forming a complete data processing closed loop: pre-generated inputs correspond to binding relationship storage, identity verification inputs correspond to verification result outputs, information entry inputs correspond to information viewing outputs, and permission setting inputs correspond to operation feedback outputs, ensuring that every input has clear output feedback and every output has corresponding input support, thus guaranteeing the feasibility and stability of the technical solution.

[0040] The methods for confirming ownership and transmitting private information are as follows: Step 1: Information carrier preparation. The cloud server pre-generates a first identification information layer 2 and a second identification information layer 4 with a unique one-to-one correspondence. Both are printed on the carrier substrate 1, and then the first scratch-off coating 3 and the second scratch-off coating 5 are covered in sequence to complete the production of the information carrier. Step 2: The sender A scratches off the first scratch-off coating 3, scans the first identification information layer 2 through the mobile terminal, enters the mobile phone number on the mobile terminal, and after the cloud server receives the mobile phone number, it sends an SMS verification code to the number. The sender A submits the received SMS verification code to the cloud server to complete the verification. After the verification is successful, the cloud server automatically completes the real-name ownership confirmation of the sender A and uniquely binds the sender A's identity information with the carrier's dual identification information. Step 3: The sender A enters private information into the cloud server via a mobile terminal. After the information is entered, the cloud server encrypts, stores, and solidifies the evidence. Step 4: The sender A chooses whether to preset the recipient B's mobile phone number. If preset, the recipient B's mobile phone number is entered into the cloud server and saved; if not preset, proceed directly to Step 5. Step 5: The sender passes the carrier to the receiver, who checks the condition of the second scratch-off coating to determine whether the carrier has been opened beforehand. Step 6: Information recipient B scratches off the second scratch-off coating 5, scans the second identification information layer 3, and triggers the cloud server to perform identity verification (when the recipient is preset): If the information recipient B's mobile phone number is preset, the information recipient B enters the corresponding mobile phone number and receives the SMS verification code sent by the cloud server. After the verification is successful, the cloud server outputs private information content for the information recipient B to view. If the recipient B's mobile phone number is not preset, the recipient B can directly view the private information output by the cloud server after scanning the QR code. Step 7: The sender A can operate the cloud server via mobile terminal to enable or disable the recipient's reply permission: When enabled, the recipient B can view the message and submit a reply. The cloud server receives the message and binds it with the carrier's dual identification information for storage, which the sender A can view; when disabled, the recipient B can only view the message and cannot submit a reply. Step 8: The cloud server records the entire process of information sender A's rights confirmation, information entry, and permission settings, as well as information recipient B's viewing and replying, forming a traceable record for ownership verification and dispute resolution.

[0041] Application Case 1: Resume Submission (Public Viewing + Reply-On Mode) In this case, information carrier C is a resume card, carrier substrate 1 is a paper card, and the first identification information layer 2 and the second identification information layer 4 are both QR codes, printed on the surface of the resume card, and then covered by the first and second scratch-off coatings in sequence. The cloud server pre-generates these two QR codes and establishes a unique correspondence, and encrypts and stores the bound information.

[0042] The sender of the information (job seeker) is the first person to scan the QR code. They scratch off the first scratch-off layer 3, scan the first identification information layer 2 (the first QR code), and enter their mobile phone number. The cloud server receives this number and sends a verification code via SMS. The sender submits the received verification code to the cloud server for verification. Upon successful verification, the job seeker's identity is confirmed, and the cloud server uniquely binds the job seeker's mobile phone number to both QR codes. Subsequently, the job seeker enters their resume information (text, images, scanned certificates, etc.) into the cloud server via their mobile phone, selects "Do not preset recipient's mobile phone number," and enables the recipient B's reply permission. After completion, the job seeker submits the resume card to the recruiter (recipient B). Upon receiving the resume card, the recruiter checks that the second scratch-off layer 5 is intact, confirming it has not been opened beforehand. They then scratch off the second scratch-off layer 5 and scan the second identification information layer 4 (the second QR code). Without needing to enter a mobile phone number for verification, they directly view the resume information output by the cloud server. Meanwhile, recruiters can submit responses (such as interview notices or communication feedback) through the cloud server. The cloud server receives these responses and stores them linked to the dual QR codes on the resume card. Job seekers can view the responses output by the cloud server by scanning the first QR code. The cloud server records the entire process, including the job seeker's confirmation time, resume entry time, recruiter's viewing time, and response submission time, creating a traceable record.

[0043] This case study addresses the issue of limited information in traditional resumes, allowing job seekers to include a wide range of content such as project examples, video works, and program files.

[0044] Application Case 2: Private Messages Between Couples (Strictly Private + One-Way Transmission Mode) In this case, a private postcard is used as the information carrier. The first and second identification information layers are both mini-program codes, which are printed on the surface of the postcard and covered with a double-layer irreversible scratch-off coating. The cloud server pre-generates the two mini-program codes and binds them to a unique correspondence.

[0045] The sender (one partner) is the first to scan the code. They scratch off the first scratch-off layer (3), scan the first mini-program code, and enter their mobile phone number. The cloud server receives this number and sends a verification code via SMS. The sender submits the verification code to complete the cloud server's verification. Once verification is successful, ownership is confirmed. The sender then enters a private message, picture, etc., into the cloud server via their mobile phone, presets the recipient's (the other partner's) mobile phone number, enters it into the cloud server, disables the recipient's reply permission, and mails the postcard to the recipient. If other people scan the first mini-program code, because they are not the first person to scan and confirm ownership, the cloud server will output blank content and display the message: "Not the owner of the information carrier, cannot view or enter information."

[0046] After receiving the postcard, the recipient checks that the second scratch-off coating 5 is intact, confirming it hasn't been opened beforehand. They then scratch off the second scratch-off coating 5, scan the second mini-program code, enter their preset mobile phone number, and receive an SMS verification code from the cloud server. Once verification is successful, the cloud server sends a private message to the recipient, who cannot submit a reply. The cloud server encrypts and stores the sender's confirmation information, the message content, and the recipient's verification time, creating a traceability record to ensure the privacy and security of information transmission.

[0047] This case addresses the issue of privacy problems inherent in traditional mailing of couple greeting cards and postcards, where the content is written on the card and can be viewed by anyone.

[0048] Application Case 3: Sealing of an Elderly Person's Last Words and Wills (Strict Privacy + Unrepairable Mode) In this case, the information carrier is a rigid plastic will card, which is printed with a visible and shared QR code or mini-program code that can access the cloud server. The first and second identification information layers are both alphanumeric codes, printed on the surface of the will card and covered with a double-layer irreversible scratch-off coating. The cloud server pre-generates the dual codes and binds them to a unique correspondence, and stores them encrypted.

[0049] The elderly person (the sender), as the first person to scan the code, in the presence of a relative or lawyer, scratches off the first scratch-off coating 3, scans the visible, shared QR code or mini-program code that allows access to the cloud server, then enters the first alphanumeric code, and enters their personal mobile phone number on their mobile device. After receiving the mobile phone number, the cloud server sends an SMS verification code to that number. The sender submits the SMS verification code to complete the cloud server verification. After successful verification, the ownership is confirmed and bound. The elderly person then uses their mobile phone to record a witness video, their will, and the contents of their will (text, voice-to-text, video, etc.) to the cloud server. A designated relative's mobile phone number is preset as the recipient, reply permissions are disabled, and the will card is sealed and stored. If other people scan the first alphanumeric code, because they are not the first person to scan the code for ownership confirmation, the cloud server will output blank content to them and display the message: "Not the owner of the information carrier, cannot view or enter information."

[0050] After the elderly person passes away, relatives retrieve the will card, check that the second scratch-off layer 5 is intact to confirm it hasn't been opened beforehand, scratch off the second scratch-off layer 5, scan the visible, shared QR code or mini-program code that allows access to the cloud server, then enter the second alphanumeric code, enter the preset mobile phone number, and complete the cloud server SMS verification. After successful verification, the cloud server outputs the will content to the relatives. The cloud server records the entire process: the time of the elderly person's rights confirmation, the time of will entry, and the time of relatives' viewing. All information is encrypted, stored, and cannot be tampered with, serving as supplementary evidence for tracing the legitimacy of the will.

[0051] This solution addresses the issue of elderly people not wishing to have their wills made public before their death, allowing for confidential storage using this method.

[0052] Example 2 like Figure 5 As shown, the difference from Embodiment 1 is that the identification information layer on the carrier substrate 1 for both the information sender A and the information receiver B to identify using their respective mobile terminals is the same identification information layer, which is called the third identification information layer 7. The third identification information layer 7 is covered with a third scratch-off coating 6.

[0053] After receiving the information carrier C, sender A scratches off the third coating 6 and scans the identification information layer of the carrier substrate 1 using a mobile terminal to access the cloud server. There, A confirms ownership and enters private information. Sender A then hands the information carrier C to receiver B, who scans the identification information layer of the carrier substrate 1 using a mobile terminal to access the cloud server and view the private information entered by sender A.

[0054] Application Case 1: Structure of Creative Cards, Postcards, and Bookmarks In this case, a single-layer structure is adopted. The carrier substrate 1 is a postcard, bookmark, or cultural and creative card. A third identification information layer 7 and a third scratch-off coating 6 are set on the carrier substrate 1. The third identification information layer 7 can be a QR code. Taking a postcard as an example, the sender A scratches off the third scratch-off coating 6, scans the third identification information layer 7 with a mobile terminal, and enters a mobile phone number and verification code to complete the initial scan for ownership confirmation and information entry: text, images, videos, voice, etc. The sender A gives the postcard to a friend (recipient B), and recipient B scans the third identification information layer 7 again to view the information content. This structure is suitable for information sharing, souvenirs, and archiving scenarios, allowing traditional postcards, bookmarks, or cultural and creative cards to carry more personalized content.

[0055] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
