The embodiment of the present application also provides a data display method.

2, a first embodiment of the data display method of the present application is proposed. In the first embodiment, the execution subject of the data display method is a display terminal, and the data display method includes:

Step S10, obtaining preset data issued by the server;

The preset data here is specifically the data issued by the server received by the display terminal, specifically the data related to TV display (specifically, it may include the display data for the display terminal to display and the intermediate data required in the process of obtaining the display data by the display terminal. Wait). Specifically, the preset data can be the data distributed by the server currently received by the display terminal, or the feedback data received after the display terminal sends a data request to the server, or the display terminal from the server at any time before. Data obtained from the server. Therefore, the preset data can be obtained from the data sent by the server currently received by the display terminal, or the preset data can be obtained by inquiring locally on the display terminal.

Step S20, extracting target information and its corresponding digital signature in the preset data; the digital signature is obtained by encrypting the data digest of the target information sent by the server using the preset private key;

Target information specifically refers to information related to display data. The target information includes data address information corresponding to the display data and/or resource files corresponding to the display data; wherein, the data address information is used to obtain all The resource file; the resource file is used to parse the display data.

Among them, in the server, the server uses a preset algorithm to calculate the data digest of the target information it needs to send, and uses the preset private key to encrypt the calculated data digest to obtain a digital signature. After the digital signature is obtained, the corresponding target information is merged to form preset data. Among them, different target information corresponds to different digital signatures.

In the acquired preset data, the file type can be identified to separate the target information and its corresponding digital signature.

Step S30, verifying the target information according to the preset public key and the digital signature;

The preset public key here and the preset private key in the server are a key pair obtained through the same algorithm. The content encrypted by the preset private key can be decrypted by the preset public key paired with it. Based on this, a preset public key can be used to decrypt the digital signature, and the decrypted content can be used to verify whether the target information has been tampered with.

Specifically, referring to FIG. 3, step S30 may include:

Step S31: Decrypt the digital signature with a preset public key to obtain a first data digest; the first data digest is obtained by the server using a preset algorithm to process the target information sent by the server;

The first data summary here specifically refers to the target information that the server needs to send by using a preset algorithm to process it. The preset algorithm here is specifically a data digest algorithm, which can be RSA's MD5 algorithm, SHA-1 algorithm, and a large number of variant algorithms.

Step S32: Use the preset algorithm to process the target information to obtain a second data summary;

The preset algorithm here is the same algorithm as the algorithm for calculating the first data digest in the server. The target information is processed according to the same preset algorithm to obtain the second data summary.

Step S33: Determine whether the first data summary and the second data summary are consistent;

If they are consistent, perform step S34; if they are not consistent, perform step S35.

Step S34, it is determined that the verification of the target information is passed;

Step S35: It is determined that the verification of the target information fails.

Among them, since the first data summary and the second data summary use the same algorithm to perform the target information, as long as the target information is not tampered with during the server sending to the display terminal, the first data summary and the second data summary must be consistent. If the target information is tampered with during the server sending to the display terminal, the first data summary and the second data summary are inconsistent. Therefore, when the first data summary is consistent with the second data summary, it can be considered that the target information received by the display terminal is the same as the target information sent by the server, the target information is verified, and the display data corresponding to the target information can be displayed ; When the first data summary is inconsistent with the second data summary, it can be considered that the target information received by the display terminal is not the same as the target information sent by the server, the target information verification fails, and the display data corresponding to the target information is prohibited from being displayed .

Step S40: After the verification of the target information is passed, display data corresponding to the target information.

Passing the verification of the target information indicates that the target information has not been tampered with during the transmission from the server to the display terminal. Therefore, the display data corresponding to the target information can be displayed, and no illegal data will appear in the display data. Among them, when displaying the display data corresponding to the target information, there are different implementation steps depending on the type of the target information. When the display target information is the data address information corresponding to the display data, the corresponding data address is accessed according to the data address information Obtain display data for display. Among them, when accessing the corresponding data address according to the data address information to obtain the display data for display, accessing the corresponding data address according to the data address information to obtain the corresponding resource file and its corresponding digital signature, and save the resource file and its corresponding digital signature To the local, when there is a display demand, read the local resource file, parse the resource file to get the display data and display it. Further, when there is a display requirement, the local resource file and its corresponding digital signature can also be used as the above-mentioned preset data. After the resource file is verified according to steps S10 to S30, the resource file is parsed to obtain the display data. And display it. In addition, when the display target information is a resource file corresponding to the display data, the resource file can be directly parsed to obtain the display data.

A data display method proposed in an embodiment of this application obtains preset data issued by a server, extracts target information in the preset data and its corresponding digital signature, and uses the preset public key and digital signature to perform the target information Verification, the display data corresponding to the target information is displayed after the verification is passed. Since the digital signature is formed in the server, if the target information is tampered with during transmission, the public key and digital signature cannot pass the verification of the target information. When the target information is verified, it indicates that the target information has not been tampered with during transmission, and the display data corresponding to the target information is the data provided by the server, and there will be no illegal data, thereby ensuring the security and accuracy of the TV data display. Since most of the data transmitted by the server and the display terminal are large, the data display method in this implementation does not involve the decryption of the entire data, and does not take up a lot of decryption time. Instead, it uses a digital signature digest verification method, which only needs to decrypt the numbers. Signing and calculating the data digest can realize the verification of the target information, which has a high verification efficiency and ensures the safety and efficiency of the TV data display.

Specifically, in the first embodiment, after step S30, the method further includes: when the verification of the target information fails, prohibiting display of the display data corresponding to the target information, thereby further ensuring that illegal data will not be displayed.

Wherein, when the target information is the data address information used to obtain the resource file, the above method is used to verify the target information, which can prevent the data address from being tampered with during the transmission process and cause the display terminal to obtain the illegal resource file, and can ensure that the display terminal The required resource files can be obtained from the accurate data address. When the target information is a resource file used to parse the display data, it can prevent the resource file from being tampered with during the transmission process and cause the display terminal to obtain illegal display data, and ensure that the display terminal can obtain a display consistent with the resources provided by the server data. When the target information includes both the data address information used to obtain the resource file and the resource file used to parse the display data, it can be ensured that the entire process from obtaining the data address to obtaining the resource file based on the data address is performed by the display terminal. It will not be affected by illegal tampering, so as to further effectively ensure that the data displayed by the display terminal will not contain illegal data.

It should be noted that the target information is not limited to the above two kinds of data, and any display-related data transmitted by the server and the display terminal can also be processed according to the relevant steps in the embodiments of the present application.

Further, based on the first embodiment, a second embodiment of the data display method of the present application is proposed. In the second embodiment, the target information includes data address information corresponding to the display data. Referring to FIG. 4, the step S10 includes:

Step S11, sending data address request information to the server;

Specifically, when the user's preset instruction is detected during the operation of the TV, it can be determined that there is a need to update the display data; in addition, the display data here can specifically refer to the data related to the display terminal power-on display, such as power-on video and power-on video. Key data such as advertisement pictures, start-up icons, desktop page pictures, etc.; therefore, after the local start-up display data is used to complete the start-up, it can be determined that there is a need to update the display data to obtain new start-up display data from the server to overwrite the local start-up display data .

Specifically, device parameters such as the model of the display terminal and area information of the region can be obtained, a uniform resource locator (URL) is generated according to the device parameters, and the generated URL is sent to the server as the data address request information.

Step S12, obtaining feedback data based on the data address request information; wherein the feedback data is data generated by the server according to the data address request information and including the data address information and its corresponding digital signature;

After the server receives the data address request information, it parses the data address request information, can locate the display terminal that issued the demand, and determine the resource file required by the demand display terminal, and generate json containing the data address (URL link) of the resource file File, the generated json file is the data address information, the data digest of the json file is calculated using a preset algorithm, the calculated data digest is encrypted with the preset private key to obtain the digital signature corresponding to the data address information, and the digital The address information and its corresponding digital signature are combined and sent to the display terminal to form the feedback data here.

Step S13: Use the feedback data as the preset data.

In this embodiment, when there is a demand for the display terminal, the data including the data address information and the digital signature can be requested from the server by sending the data address request information, so that when the data address information is verified, the data address is obtained based on the data address provided by the server. Corresponding resource files to obtain the required display data, so as to ensure that the display data of the display terminal can be updated according to actual needs. At the same time, there will be no illegal data in the acquired data, so as to ensure the accuracy of the display terminal when displaying the data Sex and safety.

Wherein, in the second embodiment, after step S30, the method further includes: when the target information verification fails, sending corresponding prompt information to the server; returning to execute the request information for sending the data address to the server step. Send prompt information to the server so that the server can redeploy new resource files and signature files, and generate new data address information; then the display terminal sends the data address request information to the server again to ensure that the display terminal can obtain what it needs data.

Step S121: Perform domain name authentication on the feedback data;

When the feedback data domain name authentication is passed, the step S13 is executed; when the feedback data domain name authentication fails, it is forbidden to obtain the resource file based on the data address information.

Since the current TV data is generally transmitted using HTTP open text, it is safe to say, and HTTPS can encrypt data and ensure its confidentiality. The data transmitted based on the HTTPS protocol can undergo domain name authentication to identify whether the data has been tampered with during the transmission process. Where the domain name authentication is passed, it indicates that the data address request information was not intercepted during the transmission to the server. Therefore, combining domain name authentication and digital signature verification to double-authenticate the feedback data can further ensure the accuracy of the data address information in the feedback data. Thereby improving the accuracy and safety of data displayed by the display terminal. When the domain name authentication fails, it indicates that the data address request information is intercepted during the transmission to the server. Therefore, it is forbidden to obtain resource files based on the data address information to avoid obtaining illegal data.
