Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method and apparatus for data interaction between a UAV PAD (Portable Android device) and a Web (World Wide Web) terminal and a server. Background Technology

[0002] This section is intended to provide background or context for the embodiments of the invention set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section.

[0003] In the field of data transmission and interaction between various drone devices and servers, existing technologies are computationally complex and resource-intensive. Publicly available algorithms are mostly implemented based on CPUs (Central Processing Units), resulting in low frame rates. In addition, some algorithms (such as the video stabilizer algorithm provided by NVIDIA) can cause abnormal image jitter after processing relatively stable input video footage, failing to meet the current needs of data interaction between various drone devices and servers. Summary of the Invention

[0004] This invention provides a method for data interaction between a drone PAD and a server, which reduces port usage, saves machine resources, and efficiently and conveniently enables data interaction between the drone PAD and the server, achieving secure data communication. The drone PAD successfully establishes a connection with the server via TCP (Transfer Control Protocol). This method is applied to the server and includes:

[0005] Receive the first authentication request sent by the drone PAD terminal. The first authentication request carries first parameter information, which includes a first signature.

[0006] Assemble the first parameter information to generate a second signature, and compare the second signature with the first signature; after the comparison is consistent, detect the drone's live streaming status based on the first parameter information; when the drone's live streaming status is live, generate a first token and send the first token to the drone's PAD terminal;

[0007] Receive private data information sent by the drone PAD, including a second token;

[0008] The second token is compared with the first token; if they match, the private data information is stored.

[0009] This invention also provides a device for data interaction between a drone PAD and a server, which reduces port usage, saves machine resources, and efficiently and conveniently enables data interaction between the drone PAD and the server, achieving secure data communication. The drone PAD successfully establishes a connection with the server via TCP. This device is applied to the server and includes:

[0010] The first receiving module is used to receive the first authentication request sent by the drone PAD after success. The first authentication request carries first parameter information, which includes a first signature.

[0011] The comparison and sending module is used to assemble the first parameter information to generate a second signature, and compare the second signature with the first signature; after the comparison is consistent, the drone live broadcast status is detected according to the first parameter information; when the drone live broadcast status is live, a first token is generated and the first token is sent to the drone PAD terminal;

[0012] The second receiving module is used to receive private data information sent by the drone PAD terminal, and the private data information includes a second token;

[0013] The comparison and storage module is used to compare the second token with the first token; after the comparison matches, it stores private data information.

[0014] This invention also provides a method for data interaction between a drone's web application and a server, which reduces port usage, saves machine resources, and efficiently and conveniently enables data interaction between the drone's web application and the server, achieving secure data exchange. The method involves the drone's web application successfully establishing a connection with the server via WebSocket. The method is applied to the server and includes:

[0015] Receive a second authentication request sent by the drone's web client. The second authentication request carries second parameter information, which includes a third signature and a third token obtained from the server after the drone's web client successfully logs in.

[0016] The system checks if the third token is valid. After confirming the validity of the third token, it assembles the second parameter information to generate a fourth signature and compares the fourth signature with the third signature. If the comparison matches, it checks the drone's live streaming status based on the second parameter information. If the drone's live streaming status is "live streaming", it checks if the drone and the server have completed TCP authentication. After confirming that TCP authentication has been completed, it forwards the second parameter information to the drone's PAD.

[0017] The system receives the response information assembled by the drone's PAD based on the second parameter information, authenticates the response information, and forwards the response information to the drone's web client for rendering after successful authentication.

[0018] This invention also provides a device for data interaction between a drone's web application and a server, which reduces port usage, saves machine resources, and efficiently and conveniently enables data interaction between the drone's web application and the server, achieving secure data exchange. The drone's web application successfully establishes a connection with the server via WebSocket. This device is applied to the server and includes:

[0019] The third receiving module is used to receive the second authentication request sent by the drone's web client. The second authentication request carries second parameter information, which includes a third signature and a third token obtained from the server after the drone's web client successfully logs in.

[0020] The detection and forwarding module is used to detect whether the third token is valid. After confirming that the third token is valid, it assembles the second parameter information to generate a fourth signature and compares the fourth signature with the third signature. After the comparison is consistent, it detects the drone's live broadcast status based on the second parameter information. When the drone's live broadcast status is live, it detects whether the drone and the server have completed TCP authentication. After confirming that TCP authentication has been completed, it forwards the second parameter information to the drone's PAD.

[0021] The authentication and forwarding module is used to receive the response information assembled by the drone PAD based on the second parameter information, authenticate the response information, and forward the response information to the drone web client for rendering after successful authentication.

[0022] This invention also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the above-described method for data interaction between the UAV PAD terminal and the Web terminal and the server.

[0023] This invention also provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the aforementioned method for data interaction between the UAV PAD and Web terminals and the server.

[0024] This invention also provides a computer program product, which includes a computer program that, when executed by a processor, implements the above-described method for data interaction between the UAV PAD terminal and the Web terminal and the server.

[0025] In this embodiment of the invention, compared with the prior art, after the drone PAD successfully establishes a TCP connection with the server, the server receives a first authentication request sent by the drone PAD. The first authentication request carries first parameter information, including a first signature. The server assembles the first parameter information to generate a second signature and compares the second signature with the first signature. If the comparison matches, the server detects the drone's live streaming status based on the first parameter information. If the drone's live streaming status is "live streaming," a first token is generated and sent to the drone PAD. The server receives private data information sent by the drone PAD, including a second token. The server compares the second token with the first token. If the comparison matches, the server stores the private data information. Thus, after the drone PAD establishes a TCP connection with the server and sends the first parameter information, the server performs multi-factor authentication. After successful multi-factor authentication, the server stores the private data information sent by the PAD. This not only reduces port usage and saves machine resources, but also efficiently and conveniently realizes data interaction between the drone PAD and the server, and achieves secure data interoperability.

[0026] In this embodiment of the invention, compared with the prior art, after the drone's web client successfully establishes a connection with the server via WebSocket, the server receives a second authentication request sent by the drone's web client. The second authentication request carries second parameter information, including a third signature and a third token obtained by the drone's web client from the server after successful login. The server checks whether the third token is valid. After confirming the validity of the third token, the server assembles the second parameter information to generate a fourth signature and compares the fourth signature with the third signature. If the comparison matches, the server checks the drone's live streaming status based on the second parameter information. If the drone's live streaming status is "live streaming," the server checks whether the drone and the server have completed TCP authentication. After confirming that TCP authentication has been completed, the server forwards the second parameter information to the drone's PAD. The server receives the response information assembled by the drone's PAD based on the second parameter information, authenticates the response information, and forwards the response information to the drone's web client for rendering after successful authentication. Thus, by adding multiple authentication methods—token verification, signature verification, and business logic verification—in the data interaction between the drone's web client and the server, not only is port usage reduced and machine resources saved, but data interaction between the drone's PAD and the server is also realized efficiently and conveniently, and secure data interoperability is also achieved.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0035] To address the technical problems existing in the prior art, this invention proposes a method for data interaction between a drone PAD and a server, which reduces port usage, saves machine resources, and efficiently and conveniently enables data interaction between the drone PAD and the server, achieving secure data exchange. Figure 1 This is a flowchart of the data interaction method between the drone PAD and the server in an embodiment of the present invention, as shown below. Figure 1 As shown, the drone's PAD successfully established a connection with the server via TCP. This method is applied to the server and includes:

[0036] Step 101: The server receives a first authentication request sent by the drone PAD terminal. The first authentication request carries first parameter information, which includes a first signature.

[0037] Step 102: The server assembles the first parameter information to generate a second signature and compares the second signature with the first signature; after the comparison is consistent, the server detects the drone's live streaming status based on the first parameter information; when the drone's live streaming status is "live streaming", the server generates a first token and sends the first token to the drone's PAD terminal.

[0038] Step 103: The server receives private data information sent by the drone PAD, which includes a second token.

[0039] Step 104: The server compares the second token with the first token; if they match, the server stores the private data information.

[0040] In one embodiment, the first parameter information further includes:

[0041] One or any combination of the following: drone serial number, timestamp in seconds, and fixed salt;

[0042] The first signature is generated based on one or any combination of the drone's SN (Serial Number), timestamp in seconds, and a fixed salt.

[0043] In practice, after the drone PAD successfully establishes a connection with the server via TCP, it sends a first authentication request to the server. This first authentication request carries first parameter information, including a first signature. Upon receiving the first authentication request, the server assembles the first parameter information to generate a second signature and compares it with the received first signature. If they match, the process proceeds to the next step; otherwise, it exits. The server uses the received first parameter information to check if the drone has applied for live streaming. If it confirms that the drone is live streaming, the process proceeds to the next step; otherwise, it exits. After successful authentication, the server generates a first token and returns it to the drone PAD. The drone PAD sends private data information to the server, including a second token. The server compares the second token with the first token. If they match, the server stores the private data information and forwards it later; otherwise, it exits.

[0044] In practice, after the drone PAD successfully establishes a connection with the server via TCP, it sends the first parameter information to the server. The first parameter information includes the first signature, as well as one or any combination of the drone SN, the timestamp in seconds, and a fixed salt. The first signature can be generated based on one or any combination of the drone SN, the timestamp in seconds, and the fixed salt.

[0045] Figure 2 This is an example diagram illustrating the detection of drone live streaming status based on the first parameter information in an embodiment of the present invention, such as... Figure 2As shown, in this embodiment of the invention, detecting the live streaming status of a drone based on the first parameter information may include:

[0046] Step 201: Based on the drone's serial number (SN), locate the live streaming record information stored on the server when the drone's PAD terminal applied for live streaming; the live streaming record information includes: drone SN and drone live streaming status;

[0047] Step 202: Determine the drone's live streaming status based on the live streaming record information.

[0048] In practice, after receiving the parameter information, the server compares the live streaming record information stored on the server when the drone PAD applied for live streaming with the drone's SN. If the drone's live streaming status is "live streaming", the next step is performed; otherwise, a verification failure is returned to the drone PAD.

[0049] In one embodiment, when the drone is in live streaming status, a TCP authentication token based on the drone's serial number (SN) is generated, and the mapping between the first token and the drone's SN is recorded.

[0050] In practice, the server generates a first token and a TCP authentication tag based on the drone's serial number (SN), and records the mapping between the first token and the drone's SN; the generated first token is sent to the drone's PAD for secondary verification between the drone's PAD and the server; the generated TCP authentication tag based on the drone's SN is used for secondary verification between the drone's web interface and the server; and the drone's PAD sends private data information to the server.

[0051] In one embodiment, the private data information further includes: drone flight control information and / or drone PAD terminal information.

[0052] In practice, after receiving the private data information, the server compares the second token in the private data information with the first token. If the comparison is consistent, it means that the drone SN corresponding to the first token exists, and that the drone's TCP authentication is successful. At the same time, it also means that the drone's communication with the server is secure and normal.

[0053] Figure 3 This is a flowchart of the data interaction method between the UAV web client and the server in an embodiment of the present invention, as shown below. Figure 3 As shown, after the drone successfully establishes a connection with the server via WebSocket on the web interface, the method includes:

[0054] Step 301: The server receives a second authentication request sent by the drone's web client. The second authentication request carries second parameter information, which includes a third signature and a third token obtained from the server after the drone's web client successfully logs in.

[0055] Step 302: The server checks whether the third token is valid. After confirming that the third token is valid, it assembles the second parameter information to generate a fourth signature and compares the fourth signature with the third signature. After the comparison is consistent, it checks the drone's live streaming status based on the second parameter information. When the drone's live streaming status is live, it checks whether the drone and the server have completed TCP authentication. After confirming that TCP authentication has been completed, it forwards the second parameter information to the drone's PAD.

[0056] Step 303: The server receives the response information assembled by the drone PAD based on the second parameter information, authenticates the response information, and forwards the response information to the drone Web client for rendering after successful authentication.

[0057] In practice, after the web client successfully establishes a connection with the server via WebSocket, it sends a second authentication request to the server. This request carries second parameter information, including a third signature and a third token obtained from the server after the drone's web client successfully logs in. Upon receiving the third token, the server checks its validity. If valid, it proceeds to the next step; otherwise, it exits. The server then assembles the second parameter information to generate a fourth signature and compares it with the received third signature. If they match, it proceeds to the next step; otherwise, it exits. The server checks if the drone is currently live-streaming. If confirmed, it proceeds to the next step; otherwise, it exits. Based on the received second parameter information, the server checks if the drone and server have completed TCP authentication. If confirmed, it proceeds to the next step; otherwise, it exits. The server forwards the second parameter information sent by the drone's web client to the drone's PAD. The drone's PAD receives the second parameter information, assembles it to generate a response, and sends it to the server. The server authenticates the received response. If authentication is successful, the server forwards the response to the drone's web client and renders it. Figure 4 This is an example diagram illustrating how the server detects the validity of a third token in an embodiment of the present invention. Figure 4 As shown in this embodiment of the invention, the server detecting the third token may include:

[0058] Step 401: The server retrieves the fourth token generated when the drone successfully logged in via the web interface;

[0059] Step 402: Compare the fourth token with the third token; if they match, the third token is confirmed to be valid.

[0060] In one embodiment, the second parameter information further includes:

[0061] Flight route request, pod request, UAV serial number, channel number, timestamp in seconds, fixed salt, or any combination thereof;

[0062] The third signature is generated based on one or any combination of the following: route request, pod request, UAV serial number, channel number, timestamp seconds, and fixed salt.

[0063] In one embodiment, detecting the drone live streaming status based on the second parameter information includes:

[0064] Based on the drone's serial number (SN), locate the live streaming record information stored on the server when the drone's PAD requested the live stream; the live streaming record information includes: drone SN and drone live streaming status;

[0065] The drone's live streaming status is determined based on the live streaming record information.

[0066] In one embodiment, the response information includes: flight path results, pod results, and a first token generated by the server and sent to the drone PAD when the drone is in live streaming status;

[0067] Authentication of response information includes:

[0068] Based on the first token in the response information and the recorded mapping between the first token and the drone SN, determine whether there is a drone SN corresponding to the first token;

[0069] After successful authentication, the response information will be forwarded to the drone's web interface for rendering, including:

[0070] Upon confirming the existence of a drone SN corresponding to the first token, the response information is assembled into the drone SN and forwarded to the drone web client for rendering.

[0071] Figure 5 This is a schematic diagram of the apparatus in the method for data interaction between the drone PAD and the server in an embodiment of the present invention, as shown below. Figure 5 As shown, the drone's PAD successfully established a connection with the server via TCP. The device includes:

[0074] The second receiving module 503 is used to receive private data information sent by the drone PAD terminal, the private data information including the second token;

The second authentication request carries second parameter information, which includes a third signature and a third token obtained from the server after the drone's web terminal successfully logs in.

[0087] The detection and forwarding module 602 is used to detect whether the third token is valid. After confirming that the third token is valid, it assembles the second parameter information to generate a fourth signature and compares the fourth signature with the third signature. After the comparison is consistent, it detects the drone's live broadcast status based on the second parameter information. When the drone's live broadcast status is live, it detects whether the drone and the server have completed TCP authentication. After confirming that TCP authentication has been completed, it forwards the second parameter information to the drone's PAD.

[0088] The authentication and forwarding module 603 is used to receive the response information assembled by the drone PAD terminal based on the second parameter information, authenticate the response information, and forward the response information to the drone web terminal for rendering after successful authentication.

[0089] In one embodiment, the detection and forwarding module 602 is specifically used for:

[0103] This invention also provides a computer program product, which includes a computer program that, when executed by a processor, implements the above-mentioned method for data interaction between the UAV PAD terminal and the Web terminal and the server.

[0104] In summary, in this embodiment of the invention, compared with the prior art, after the drone PAD successfully establishes a TCP connection with the server, the server receives a first authentication request sent by the drone PAD. The first authentication request carries first parameter information, including a first signature. The server assembles the first parameter information to generate a second signature and compares the second signature with the first signature. If the comparison is consistent, the server detects the drone's live streaming status based on the first parameter information. If the drone's live streaming status is "live streaming," a first token is generated and sent to the drone PAD. The server receives private data information sent by the drone PAD, including a second token. The server compares the second token with the first token. If the comparison is consistent, the server stores the private data information. Thus, after the drone PAD establishes a TCP connection with the server and sends the first parameter information, the server performs multi-factor authentication. After successful multi-factor authentication, the server stores the private data information sent by the PAD. This not only reduces port usage and saves machine resources, but also efficiently and conveniently realizes data interaction between the drone PAD and the server, and achieves secure data interoperability.

[0105] In this embodiment of the invention, compared with the prior art, after the drone's web client successfully establishes a connection with the server via WebSocket, the server receives a second authentication request sent by the drone's web client. The second authentication request carries second parameter information, including a third signature and a third token obtained by the drone's web client from the server after successful login. The server checks whether the third token is valid. After confirming the validity of the third token, the server assembles the second parameter information to generate a fourth signature and compares the fourth signature with the third signature. If the comparison matches, the server checks the drone's live streaming status based on the second parameter information. If the drone's live streaming status is "live streaming," the server checks whether the drone and the server have completed TCP authentication. After confirming that TCP authentication has been completed, the server forwards the second parameter information to the drone's PAD. The server receives the response information assembled by the drone's PAD based on the second parameter information, authenticates the response information, and forwards the response information to the drone's web client for rendering after successful authentication. Thus, by adding multiple authentication methods—token verification, signature verification, and business logic verification—in the data interaction between the drone's web client and the server, not only is port usage reduced and machine resources saved, but data interaction between the drone's PAD and the server is also realized efficiently and conveniently, and secure data interoperability is also achieved.

The device is applied to the server and includes: The first receiving module is used to receive a first authentication request sent by the UAV PAD terminal. The first authentication request carries first parameter information, which includes a first signature. The first signature is generated based on the remaining information in the first parameter information excluding the first signature. The comparison and sending module is used to assemble the first parameter information to generate a second signature, and compare the second signature with the first signature; after the comparison is consistent, the drone live broadcast status is detected according to the first parameter information; when the drone live broadcast status is live, a first token is generated and the first token is sent to the drone PAD terminal; The second receiving module is used to receive private data information sent by the drone PAD terminal, and the private data information includes a second token; The comparison and storage module is used to compare the second token with the first token; after the comparison matches, it stores private data information. The drone's web interface establishes a connection with the server via WebSocket. The third receiving module is used to receive the second authentication request sent by the UAV Web client. The second authentication request carries second parameter information, which includes one or any combination of the third signature, flight path request, pod request, UAV SN, channel number, timestamp in seconds, and fixed salt. The third signature is generated based on one or any combination of the flight path request, pod request, UAV SN, channel number, timestamp in seconds, and fixed salt. The third token is obtained from the server after the UAV Web client successfully logs in. The detection and forwarding module is used to detect whether the third token is valid. After confirming that the third token is valid, it assembles the second parameter information to generate a fourth signature and compares the fourth signature with the third signature. After the comparison is consistent, it detects the drone's live streaming status based on the second parameter information. When the drone's live streaming status is live, it detects whether the drone PAD and the server have completed TCP authentication. After confirming that TCP authentication has been completed, it forwards the second parameter information to the drone PAD. The authentication and forwarding module is used to receive the response information assembled by the drone PAD based on the second parameter information, authenticate the response information, and forward the response information to the drone web client for rendering after successful authentication.
