The embodiment of the invention provides a display system.
Referring to fig. 1, the display system includes a display terminal 100 and a server 200. The display terminal 100 is in data communication connection with the server 200. The server 200 may provide the display terminal 100 with display and operation related data required by the display terminal. In this embodiment, the server 200 is specifically a cloud server. The display terminal 100 may be embodied as a display device such as a television.
In an embodiment of the present invention, referring to fig. 1, a display terminal 100 includes: a processor 1001, such as a CPU, memory 1002, or the like. The memory 1002 may be a high-speed RAM memory or a non-volatile memory (e.g., a disk memory). The memory 1002 may alternatively be a storage device separate from the processor 1001.
As shown in fig. 1, a data display program may be included in the memory 1002, which is a readable storage medium. In the apparatus shown in fig. 1, the processor 1001 may be configured to call a data display program stored in the memory 1002, and perform operations of relevant steps of any one of the first to fourth embodiments of the data display method in the following embodiments.
In the embodiment of the present invention, referring to fig. 1, a server 200 includes: a processor 2001 such as a CPU, memory 2002, and the like. The memory 2002 may be a high-speed RAM memory or a non-volatile memory (e.g., a disk memory). The memory 2002 may alternatively be a storage device separate from the processor 2001 described previously. The processor 2001 is communicatively connected to the memory 2002.
As shown in fig. 1, a memory 2002 as a readable storage medium may include a data display program therein. In the apparatus shown in fig. 1, the processor 2001 may be configured to call a data display program stored in the memory 2002 and perform operations of relevant steps of any one of the fifth embodiments of the data display method in the following embodiments.
The embodiment of the invention also provides a data display method.
Referring to fig. 2, a first embodiment of a data display method of the present invention is provided. In a first embodiment, an execution subject of a data display method is a display terminal, and the data display method includes:
step S10, acquiring preset data sent by a server;
the preset data is specifically data sent by the server and received by the display terminal, and specifically data related to television display (specifically, the preset data may include display data for the display terminal to display and intermediate data required by the display terminal in the process of acquiring the display data). Specifically, the preset data may be data which is currently received by the display terminal and is automatically distributed by the server, or feedback data which is received after the display terminal sends a data request to the server, or data which is acquired by the display terminal from the server at any previous time. Therefore, the data sent by the server can be currently received by the display terminal to obtain the preset data, and the preset data can also be obtained by local query of the display terminal.
Step S20, extracting target information in the preset data and a digital signature corresponding to the target information; the digital signature is obtained by encrypting a data abstract of target information sent by the server by adopting a preset private key;
the target information specifically refers to information related to display data, and the target information includes data address information corresponding to the display data and/or a resource file corresponding to the display data; wherein, the data address information is used for acquiring the resource file; the resource file is used for analyzing to obtain the display data.
In the server, the server calculates the data summary of the target information required to be sent by the server by adopting a preset algorithm, and encrypts the calculated data summary by using a preset private key to obtain a digital signature. And after the digital signature is obtained, combining the corresponding target information to form preset data. Wherein, different target information corresponds to different digital signatures.
In the acquired preset data, the file type in the preset data can be identified so as to separate and obtain the target information and the corresponding digital signature.
Step S30, verifying the target information according to a preset public key and the digital signature;
the preset public key 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 matched with the preset private key. Based on the above, the preset public key can be adopted to decrypt the digital signature, and whether the target information is falsified or not can be verified according to the content obtained by decryption.
Specifically, referring to fig. 3, step S30 may include:
step S31, decrypting the digital signature by adopting a preset public key to obtain a first data abstract; the first data abstract is obtained by processing target information sent by the server by adopting a preset algorithm;
the first data summary specifically refers to that the server processes target information required to be sent by the server by using a preset algorithm. The preset algorithm is specifically a data summarization algorithm, and may be an MD5 algorithm of RSA corporation, an SHA-1 algorithm, a great number of variants thereof, and the like.
Step S32, processing the target information by adopting the preset algorithm to obtain a second data abstract;
the preset algorithm is the same algorithm as the algorithm for calculating the first data summary in the server. And processing the target information according to the same preset algorithm to obtain a second data abstract.
Step S33, determining whether the first data digest and the second data digest are consistent;
if they match, step S34 is executed, and if they do not match, step S35 is executed.
Step S34, determining that the target information passes verification;
step S35, determining that the target information verification fails.
The first data abstract and the second data abstract are carried out on the target information by adopting the same algorithm, so that the first data abstract and the second data abstract are necessarily consistent as long as the target information is not tampered in the process of sending the target information to the display terminal by the server, and the first data abstract and the second data abstract are not consistent if the target information is tampered in the process of sending the target information to the display terminal by the server. Therefore, when the first data abstract is consistent with the second data abstract, the target information received by the display terminal is considered to be the same as the target information sent by the server, the target information passes verification, and the display data corresponding to the target information can be displayed; when the first data abstract is inconsistent with the second data abstract, the target information received by the display terminal is considered to be different from the target information sent by the server, the target information is not verified, and the display data corresponding to the target information is forbidden to be displayed.
And step S40, after the target information passes the verification, displaying the display data corresponding to the target information.
The verification of the target information is passed, which indicates that the target information is not tampered in the process of transmitting the target information to the display terminal by the server, so that the display data corresponding to the target information can be displayed, and illegal data cannot appear in the display data. When the display target information is data address information corresponding to the display data, the corresponding data address is accessed according to the data address information to obtain the display data for display. When the corresponding data address is accessed according to the data address information to obtain the display data for displaying, the corresponding resource file and the corresponding digital signature are obtained according to the corresponding data address accessed by the data address information, the resource file and the corresponding digital signature are stored locally, when the display requirement exists, the local resource file is read, and the resource file is analyzed to obtain the display data for displaying. Further, when there is a display requirement, the local resource file and the corresponding digital signature may be used as the preset data, and after the resource file is verified according to steps S10 to S30, the resource file is analyzed to obtain display data and displayed. In addition, when the display target information is the resource file corresponding to the display data, the resource file can be directly analyzed to obtain the display data.
The invention provides a data display method, which comprises the steps of obtaining preset data issued by a server, extracting target information in the preset data and a digital signature corresponding to the target information, verifying the target information by adopting a preset public key and the digital signature, and displaying display data corresponding to the target information after the target information passes the verification. Because the data transmitted by the server and the display terminal are mostly large, the data display method does not involve decryption of the whole data, does not occupy a large amount of decryption time, adopts a digital signature abstract verification method, can realize verification of target information only by decrypting the digital signature and calculating the data abstract, has high verification efficiency, and ensures safe and efficient television data display.
Specifically, in the first embodiment, after step S30, the method further includes: and when the target information is not verified, prohibiting display of display data corresponding to the target information, thereby further ensuring that illegal data cannot be displayed.
When the target information is data address information used for acquiring the resource file, the target information is verified in the above mode, so that the situation that the display terminal acquires an illegal resource file due to tampering of the data address in the transmission process can be avoided, and the display terminal can acquire the required resource file from the accurate data address. When the target information is the resource file used for analyzing and obtaining the display data, the display terminal can be prevented from obtaining illegal display data due to tampering of the resource file in the transmission process, and the display terminal can be ensured to obtain the display data consistent with the resources provided by the server. When the target information simultaneously comprises the data address information for acquiring the resource file and the resource file for analyzing to obtain the display data, the display terminal can be ensured not to be influenced by illegal tampering in the whole process from the data address acquisition to the resource file acquisition according to the data address, and therefore the data displayed by the display terminal can be further effectively ensured not to contain illegal data.
It should be noted that the target information is not limited to the above two data, and any data related to display transmitted by the server and the display terminal may be processed according to the relevant steps of the embodiment of the present invention.
Further, a second embodiment of the data display method is provided based on the first embodiment. In the second embodiment, the target information includes data address information corresponding to the display data, and referring to fig. 4, the step S10 includes:
step S11, sending data address request information to the server;
specifically, when a preset instruction of a user is detected in the running process of the television, the updating requirement of the display data is judged to exist; in addition, the display data may specifically refer to data related to display of the display terminal when the terminal is powered on, such as key data of a power-on video, a power-on advertisement picture, a power-on icon, a desktop page picture, and the like; therefore, after the local startup display data is adopted to complete startup, the existence of the updating requirement of the display data can be judged, so that the new startup display data is obtained from the server to cover the local startup display data.
Specifically, the device parameters such as the model of the display terminal and the regional information of the area where the display terminal is located may be acquired, a Uniform Resource Locator (URL) may be generated according to the device parameters, and the generated URL may be sent to the server as the data address request information.
Step S12, obtaining feedback data based on the data address request information; the feedback data is generated by the server according to the data address request information and comprises the data address information and a digital signature corresponding to the data address information;
after receiving the data address request information, the server analyzes the data address request information, can locate a display terminal sending a demand, determines a resource file required by the demand display terminal, generates a json file containing a data address (URL link) of the resource file, takes the generated json file as data address information, calculates a data abstract of the json file by adopting a preset algorithm, encrypts the calculated data abstract by adopting a preset private key to obtain a digital signature corresponding to the data address information, and combines and sends the digital address information and the corresponding digital signature to the display terminal to form feedback data.
And step S13, taking the feedback data as the preset data.
In this embodiment, when the display terminal has a requirement, data including data address information and a digital signature may be requested from the server by sending the data address request information, so that when the data address information passes verification, a corresponding resource file is obtained based on the data address provided by the server to obtain the required display data, thereby ensuring that the display data of the display terminal can be updated according to the actual requirement, and meanwhile, the obtained data does not have illegal data, and ensuring the accuracy and the security of the display terminal when displaying the data.
In the second embodiment, after step S30, the method further includes: when the target information is not verified, sending corresponding prompt information to the server; and returning to execute the step of sending the data address request information to the server. Sending prompt information to the server so that the server can redeploy new resource files and signature files and generate new data address information; and then the display terminal sends the data address request information to the server again, so that the display terminal can acquire the required data.
Further, a third embodiment of the data display method is provided based on the second embodiment. In the third embodiment, referring to fig. 5, the step of sending data address request information to the server in step S11 includes:
step S111, sending the address request information to the server through an encryption transmission protocol;
the encrypted transport protocol here refers in particular to the HTTPS protocol.
Before step S13, the method further includes:
step S121, performing domain name authentication on the feedback data;
when the feedback data domain name authentication is passed, performing the step S13; and when the feedback data domain name authentication is failed, forbidding to acquire the resource file based on the data address information.
Security is compromised because current television data is typically transmitted using HTTP open text, whereas HTTPs can encrypt data and ensure its confidentiality. Data transmitted based on the HTTPS protocol may be subjected to domain name authentication to identify whether the data has been tampered with during transmission. The method comprises the steps that domain name authentication is passed, and the fact that data address request information is not intercepted in the process of being transmitted to a server is indicated, so that double authentication is conducted on feedback data by combining domain name authentication and digital signature verification, the accuracy of data address information in the feedback data can be further guaranteed, and the accuracy and the safety of display data of a display terminal are improved. When the domain name authentication is failed, the data address request information is intercepted in the process of being transmitted to the server, so that the resource file is forbidden to be acquired based on the data address information, and the illegal data is prevented from being acquired.
Further, a fourth embodiment of the data display method of the present application is provided based on the second or third embodiment. In a fourth embodiment, when the data address information is verified, the step of displaying the display data corresponding to the target information includes: extracting a data address in the data address information; acquiring a resource file and a corresponding digital signature thereof from a server according to the data address; the acquired resource file and the corresponding digital signature are used as the preset data, and the resource file is used as the target information; returning to the step of extracting the target information in the preset data and the digital signature corresponding to the target information, and verifying the target information according to a preset public key and the digital signature; when the resource file passes the verification, analyzing the resource file to obtain the display data; and displaying the display data.
