Description

Technical Field

[0001] This invention relates to the field of information transmission technology, and more particularly to a method for generating and targeted pushing personalized response content based on external requests in cross-domain information interaction. Background Technology

[0002] In cross-domain information publishing systems (such as those with physical isolation between internal and external networks and unidirectional transmission), the external network often needs to submit requests to the internal network, such as querying specific business data, requesting certain reports, or requesting the execution result of a certain command. Traditional systems rely on bidirectional network communication and can obtain processing status, personalized response content, and delivery success / failure confirmation through APIs / Sockets. However, in unidirectional channel systems (such as HDMI + unidirectional optical devices), the following problems exist: ACKs cannot be directly sent back, making it impossible to know whether the delivery was successful; personalized response content cannot be directly generated in response to external requests, requiring significant manual intervention; differentiated and customized content cannot be provided for different users / terminals; there is a lack of a correlation mechanism between request content, response content, and delivery confirmation; and the complete closed-loop process of request-response-delivery cannot be tracked. Summary of the Invention

[0003] To address the above technical issues, the first aspect of this application proposes a personalized response content generation and targeted push system based on external requests, which includes: an external network request generation module, a request parameter packaging module, a push receiving module, a local receipt generator, and a receipt upload module; an internal network content generation and review system, a receipt comparison and log manager; a first unidirectional transmission link, a second unidirectional transmission link, and a third unidirectional transmission link;

[0004] The request generation module is used to generate structured requests, which include user identity ID, access permissions, and request parameters;

[0005] The request parameter packaging module is used to serialize the request to form a link request ID, and send the processed request data to the first unidirectional transmission link;

[0006] The intranet content generation and review system is used to: receive request data from the first unidirectional transmission link and parse the request data; verify the user's access permissions based on the parsed user identity ID and locate the target terminal bound to it; automatically generate personalized response content based on the user identity ID, access permissions, and request parameters, and assign a unique delivery sequence number to the personalized response content; package the generated personalized response content and delivery sequence number, and encode them into a push package to adapt to the transmission requirements of the second unidirectional transmission link; and send the push package to the second unidirectional transmission link.

[0007] The push receiving module is used to receive push packets from the second unidirectional transmission link, restore the personalized response content for users to view, and extract the delivery sequence number;

[0008] The local receipt generator is used to generate a status receipt based on the reception result of the received push packet, and to encapsulate the status receipt to include the delivery sequence number.

[0009] The receipt upload module transmits the encapsulated status receipt back to the intranet via a third unidirectional transmission link;

[0010] The acknowledgment comparison and log manager receive the returned status acknowledgment and compare it with the originally generated delivery sequence number; based on the comparison result, a request execution report is generated.

[0011] The second aspect of this application proposes a method for generating and targeted pushing personalized response content based on external requests, the method comprising the following steps:

[0012] S1. Initiate a structured request, which includes the user's identity ID, access permissions, and request parameters;

[0013] S2. Serialize the request to form a link request ID, and send the processed request data to the first unidirectional transmission link;

[0014] S3. Receive request data from the first unidirectional transmission link and parse the request data;

[0015] S4. Based on the parsed user identity ID, verify their access permissions and find the target terminal information bound to them;

[0016] S5. Automatically generate personalized response content based on user identity ID, access permissions, and request parameters;

[0017] S6. Assign a unique delivery sequence number to each generated personalized response content;

[0018] S7. Package the generated personalized response content and delivery sequence number into a push package to adapt to the transmission requirements of the second unidirectional transmission link;

[0019] S8. Send the encoded push packet to the second unidirectional transmission link;

[0020] S9. The external network receives push packets from the second unidirectional transmission link, restores the personalized response content for users to view, and extracts the delivery sequence number;

[0021] S10. Generate a status receipt based on the reception result of the received push packet, and write the status receipt into the local link log of the external network;

[0022] S11. Encapsulate the status receipt to include the delivery sequence number, and transmit the encapsulated status receipt back to the intranet via the third unidirectional transmission link;

[0023] S12. Receive the status acknowledgment returned from the intranet, compare it with the originally generated delivery sequence number, and generate a request execution report based on the comparison result.

[0024] This invention achieves automated content generation and targeted push driven by external requests while maintaining physical isolation between internal and external networks and network protocol interruption. It also solves the technical problem of "unknown delivery status" in traditional one-way isolation systems and provides end-to-end observability and auditing capabilities.

[0030] The present invention will now be described by way of example with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Furthermore, the described embodiments are only some, not all, of the embodiments of the present invention.

[0031] refer to Figure 1 The diagram illustrates a structural block diagram of a personalized response content generation and targeted push system based on external requests, according to some embodiments of the present invention.

[0032] The system includes: an external network request generation module 10, a request parameter packaging module 11, a push receiving module 20, a local receipt generator 21, and a receipt upload module 22; an internal network content generation and review system 30, a receipt comparison and log manager 23; and a first unidirectional transmission link 12, a second unidirectional transmission link 19, and a third unidirectional transmission link 24.

[0033] The request generation module 10 is used to generate structured requests, which include user identity ID, access permissions, request parameters, and target terminal identifier.

[0034] User identities can be roles, organizations, or departments; access permissions can include permission scopes, such as accessible field levels and viewable report ranges; request parameters can include time ranges, business scopes, geographical regions, request types (daily reports, weekly reports, event information, risk alerts, data overviews), and usage scenarios (leadership dashboards, emergency alerts, equipment monitoring, data analysis). The final personalized content returned can include: data reports (with chart rendering), customized video clips / stitching, news feeds, text summaries, and AI-generated descriptions.

[0035] The request parameter packaging module 11 serializes the request to form a link request ID and signs the request data, and sends the processed request data to the first unidirectional transmission link 12.

[0036] The intranet content generation and review system 30 is used to perform the following steps S1-S8:

[0037] S1. Receive request data from the first unidirectional transmission link, parse the request data and verify its validity. If the verification passes, continue to perform the following actions; otherwise, end the process.

[0038] S2. Based on the parsed user identity ID, verify their access permissions and locate the target terminal bound to it. Since this step can be performed in real time, the structured request initiated by the request generation module 10 does not necessarily need to include the target terminal identifier.

[0039] S3. Automatically generate personalized response content based on user identity ID, access permissions, and request parameters.

[0040] S4. Assign a unique delivery sequence number (SeqID) to each generated personalized response content; this SeqID is bound to the link request ID, user identity ID, target terminal ID and timestamp, serving as the unique credential for subsequent tracking and confirmation.

[0041] SeqID is unforgeable, for example, by using a signature or hash function.

[0042] S5. Package the generated personalized response content with the SeqID and encode it into a push package to adapt to the transmission requirements of the second unidirectional transmission link.

[0043] According to further embodiments of the present invention, multiple personalized response contents can be constructed into an image frame in the order in which they are requested, with an index table placed at the frame header of the image frame. The index table records the SeqID corresponding to each personalized response content block, as well as the starting offset and length of that content within the image frame. The frame body structure then arranges each personalized response content block sequentially and closely. After an image frame is encapsulated, it is then pushed to the next stage. Figure 3 , Figure 4 and Figure 5 The diagrams illustrate the image frame structures containing personalized response content with multiple SeqIDs at several sequential moments according to some embodiments of the present invention. As shown, following the frame header, multiple blocks of personalized response content, located by an index table, are arranged closely together. Figure 4 As an intermediate moment in the image frame, it makes full use of Figure 3 and Figure 5 The SeqID1-SeqID3 transmission gap is used to transmit the content corresponding to the SeqID4-SeqID6 link request.

[0044] S6. Send the encoded push packet to the second unidirectional transmission link.

[0045] S7. Receive push packets from the second unidirectional transmission link, restore the personalized response content for the user to view, and extract the SeqID.

[0046] In cases involving the splicing of personalized response content with multiple SeqIDs, the push receiving module is also used to restore the image frame and splice the personalized response content corresponding to the same SeqID to form complete content.

[0047] According to some embodiments of the present invention, each piece of content is strictly bound to: the requesting subject (user / department), the specified target terminal (MAC / serial number / authorization file), the content access permission, and the security level. Therefore, each piece of content can only be decoded and read by the corresponding target terminal.

[0048] S8. Generate a status receipt based on the reception result of the received push packet, and write the status receipt into the local link log of the external network.

[0049] S9. Encapsulate the status receipt to include the SeqID, and transmit the encapsulated status receipt back to the intranet via the third unidirectional transmission link.

[0050] In some embodiments, the first and third unidirectional transmission links may be low-bandwidth data diodes or logical unidirectional channels implemented offline via methods such as QR code scanning or USB flash drive copying.

[0051] S10. Receive the returned status receipt, compare it with the originally generated SeqID, and generate a request execution report based on the comparison result.

[0052] The generated SeqID is compared with the original SeqID. Based on the comparison result, a request execution report is generated, including: if the SeqID matches and the status is successful, the interaction is marked as "completed"; if no status receipt is received within a timeout or the status receipt shows failure, an exception alarm or retry mechanism is triggered. Simultaneously, a full-link log including request, generation, push, and receipt is recorded.

[0053] refer to Figure 2 The diagram illustrates a detailed structural block diagram of a system according to further embodiments of the present invention. This diagram further refines the processing flow on the intranet side.

[0054] The system includes: an external network request generation module 100, a request parameter packaging module 110, a push receiving module 200, a local receipt generator 210, and a receipt upload module 220; an internal network request parser 130, a user / terminal binding management module 140, a personalized response content generation engine 150, a delivery sequence number generator 160, a content packaging and encoder 170, a content push scheduler 180, and a receipt comparison and log manager 230; and a first unidirectional transmission link 120, a second unidirectional transmission link 190, and a third unidirectional transmission link 240.

[0055] The request generation module 100 initiates a structured request, which includes the user's identity ID, access permissions, request parameters (such as time range, business type, etc.) and the target terminal identifier.

[0056] The request parameter packaging module 110 serializes the request to form a link request ID and sends the processed request data to the first unidirectional transmission link 120. The request data can also be signed here.

[0057] Data is pushed to the intranet via the first unidirectional transmission link 120.

[0058] A unidirectional transmission link (or unidirectional channel) refers to a physical channel that supports only unidirectional data flow. According to some embodiments of the present invention, a first unidirectional transmission link, a second unidirectional transmission link, and a third unidirectional transmission link may include: an electro-optical conversion unidirectional optical transmitter for converting electrical signals into optical signals; a unidirectional optical fiber; and an opto-optical conversion unidirectional optical receiver for converting optical signals back into electrical signals. This structure ensures unidirectionality at the physical layer. In this application, the electro-optical conversion unidirectional optical transmitter can convert electrical signals into optical signals, but cannot convert optical signals back into electrical signals; the opto-optical conversion unidirectional optical receiver can convert optical signals into electrical signals, but cannot convert electrical signals back into optical signals. Depending on the actual situation, there may be a video cable (such as an HDMI cable) or other connecting line before the electro-optical conversion unidirectional optical transmitter to connect the transmitter and the preceding component that transmits the electrical signal to it. Therefore, the unidirectional transmission link of the present invention also includes some necessary connecting lines. The unidirectional transmission link can also be any link that can realize physically unidirectional signal transmission.

[0059] The request parser 130 is used to receive request data from the first unidirectional transmission link 120 and parse the request data. In addition to the previously performed signature verification, this step also includes a validity check.

[0060] Request parser 130 can also reject requests that are malformed or have invalid signatures.

[0061] The user / terminal binding management module 140 verifies the user's access permissions based on the parsed user identity ID and locates the target terminal information bound to it. This ensures that subsequently generated content can only be accessed by authorized target terminals and users.

[0062] The personalized response content generation engine 150 automatically generates personalized response content based on the user's identity ID, access permissions, and request parameters. For example, it can generate specific data reports, render visual charts, or generate specific video clips based on the time range in the request parameters.

[0063] The delivery sequence number generator 160 is used to assign a unique delivery sequence number (SeqID) to each generated personalized response content. This SeqID is bound to the link request ID, user identity ID, terminal ID, and timestamp, serving as a unique credential for subsequent tracking and confirmation.

[0064] The content packaging and encoder 170 packages the generated personalized response content with the SeqID and encodes it into a push packet (e.g., encoded as a video stream signal or a specific proprietary protocol format) to adapt to the transmission requirements of the second unidirectional transmission link.

[0065] When a large number of terminals on the external network require different personalized response content at different request frequencies (e.g., content 1 is pushed every 10 seconds, content 2 every 20 seconds, and content 3 every 40 seconds), if the content push scheduler 180 sends the personalized response content to each request one by one via a unidirectional transmission link (e.g., an HDMI cable, an electro-optical converter connected to the HDMI cable, a unidirectional optical fiber, and an opto-optical converter), then 19,000 transmission operations would be performed every 2 minutes, resulting in huge overhead. Therefore, this application further proposes that the content packaging and encoder 170 is also used to construct multiple personalized response contents into an image frame according to the order in which they are requested, with an index table placed at the frame header of the image frame; the index table records the SeqID corresponding to each personalized response content block, as well as the starting offset and length of the content in the image frame; the frame body structure arranges each personalized response content block tightly in sequence. After an image frame is packaged, it is then pushed to the next stage.

[0066] Figure 3 , Figure 4 and Figure 5 The diagrams illustrate the structure of image frames containing multiple SeqIDs at several sequential moments according to some embodiments of the present invention. As shown, following the frame header, multiple blocks of personalized response content located by an index table are arranged closely together. Figure 4 As an intermediate moment in the image frame, it makes full use of Figure 3 and Figure 5 The SeqID1-SeqID3 transmission gap is used to transmit the content corresponding to the SeqID4-SeqID6 link request.

[0067] The content push scheduler 180 is responsible for managing the sending queue and pushing the encoded push packets to the external network through the second unidirectional transmission link 190.

[0068] The push receiving module 200 receives push packets from the second unidirectional transmission link 190, restores the personalized response content for the user to view, and extracts the SeqID.

[0069] When multiple personalized response contents are encapsulated in an image frame, the image frame will be restored here, and the personalized response contents corresponding to the same SeqID will be spliced ​​together to form complete content.

[0070] The local receipt generator 210 is used to generate a status receipt (e.g., SeqID=1001, Status=Success) locally based on the reception result of the received push packet, encapsulate the status receipt to include the SeqID, and write the status receipt to the local link log of the external network.

[0071] The receipt upload module 220 transmits the status receipt back to the intranet via the third unidirectional transmission link 240. In some embodiments, the third unidirectional transmission link may be a low-bandwidth data diode, or a logical unidirectional channel implemented offline via methods such as QR code scanning or USB flash drive copying.

[0072] The receipt comparison and log manager 230 receives the returned status receipt and compares it with the originally generated SeqID; based on the comparison result, it generates a request execution report. If the SeqID matches and the status is successful, the interaction is marked as "completed"; if no status receipt is received within a timeout or the status receipt shows failure, an exception alarm or retry mechanism is triggered. Simultaneously, the receipt comparison and log manager is responsible for recording a complete log chain including request, generation, push, and receipt.

[0073] Figure 6 A flowchart illustrating a method for generating and targeted push of personalized response content based on external requests according to some embodiments of the present invention is shown; as shown in the figure, the method includes the following steps:

[0074] S1. Initiate a structured request, which includes the user's identity ID, access permissions, and request parameters.

[0075] Request parameters can include, for example, time range, business type, etc.

[0076] S2. Serialize the request to form a link request ID and sign the request data, and send the processed request data to the first unidirectional transmission link.

[0077] S3. Receive request data from the first unidirectional transmission link and parse the request data.

[0078] S4. Based on the parsed user identity ID, verify their access permissions and find the target terminal information bound to them.

[0079] S5. Automatically generate personalized response content based on user identity ID, access permissions, and request parameters.

[0080] For example, it can generate specific data reports, render visual charts, or generate specific video clips based on the time range in the request parameters.

[0081] S6. Assign a unique delivery sequence number (SeqID) to each personalized response.

[0082] According to some embodiments of the present invention, the SeqID is bound to the link request ID, user identity ID, terminal ID and timestamp, serving as a unique credential for subsequent tracking and confirmation.

[0083] S7. Package the generated personalized response content with the SeqID and encode it into a push package to adapt to the transmission requirements of the second unidirectional transmission link.

[0084] According to further embodiments of the present invention, as described above, an index table can be constructed and placed in the frame header of the image frame. The index table records the SeqID corresponding to each personalized response content block, as well as the starting offset and length of that content within the image frame. The frame body structure then sequentially and closely arranges each personalized response content block. After an image frame is encapsulated, it is then pushed to the next stage.

[0085] Figure 3 , Figure 4 and Figure 5 The diagrams illustrate the structure of image frames containing multiple SeqIDs at several sequential moments according to some embodiments of the present invention. As shown, following the frame header, multiple blocks of personalized response content located by an index table are arranged closely together. Figure 4 As an intermediate moment in the image frame, it makes full use of Figure 3 and Figure 5 The SeqID1-SeqID3 transmission gap is used to transmit the content corresponding to the SeqID4-SeqID6 link request.

[0086] S8. Send the push packet to the second unidirectional transmission link.

[0087] S9. The external network receives push packets from the second unidirectional transmission link, restores the personalized response content for users to view, and extracts the SeqID.

[0088] S10. Generate a status receipt based on the reception result of the received push packet, and write the status receipt into the local link log of the external network.

[0089] S11. Encapsulate the status receipt to include the SeqID, and transmit the encapsulated status receipt back to the intranet via the third unidirectional transmission link.

[0090] S12. Receive the status acknowledgment returned from the intranet and compare it with the originally generated SeqID; generate a request execution report based on the comparison result.

[0091] If the SeqID matches and the status is successful, the interaction is marked as "completed". If no status receipt is received within a timeout period or the status receipt shows failure, an exception alarm or retry mechanism is triggered. Meanwhile, the receipt comparison and log manager are responsible for recording a complete log chain including requests, generation, pushes, and receipts.

[0092] Figure 7 A sequence diagram is shown for a method of generating personalized response content and targeted push based on external requests according to some embodiments of the present invention. As shown in the figure, the method includes:

[0093] 1. Submitting a structured request: An external terminal submits a request, which enters the intranet via a one-way channel from the outside to the inside.

[0094] 2. Intranet Processing: After receiving the request, the intranet sequentially performs user identity resolution / permission judgment, generates personalized response content (Report / Video / Info) based on parameters, and generates a delivery confirmation sequence number (SeqID).

[0095] 3. Push Packet: The intranet pushes the push packet (Content + SeqID) to the external terminal via the intranet-to-external one-way channel.

[0096] 4. Generate local receipt: After receiving the push packet, the external terminal generates a receipt status (SeqID, result) locally and writes the receipt status to the external network link log.

[0097] 5. Sending back receipts: Sending receipts (Ack) back to the intranet via a third one-way channel or offline methods (such as USB flash drive or CD).

[0098] 6. Confirm delivery result: The internal network receives the receipt, compares the sequence number with the status, and confirms the delivery result, thereby achieving quasi-two-way closed-loop confirmation.

[0099] Furthermore, for more details regarding the above process, please refer to the preceding sections. Figure 1-6 The descriptions provided will not be repeated here.

[0100] Through the above implementation methods, this invention achieves automated content generation and targeted push driven by external requests while maintaining physical isolation between internal and external networks and network protocol interruption. It also solves the technical problem of "unknown delivery status" in traditional one-way isolation systems and provides end-to-end observability and auditing capabilities.

[0101] It should be noted that, for ease of understanding, this application has broken down each step in the method and each module in the system in detail. However, those skilled in the art will understand that, depending on the actual implementation needs, each step and module can be further broken down or reorganized, and these are all within the scope of the present invention.
