Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In order to make the technical solutions provided in the embodiments of the present application better understood and make the above objects, features and advantages of the embodiments of the present application more comprehensible, the technical solutions in the embodiments of the present application are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a flow chart of a data display control method provided in an embodiment of the present application is schematically shown, where the data display control method may be applied to a data display device, as shown in fig. 1, the data display control method may include the following steps:
it should be noted that, in the embodiment of the present application, if not specifically stated, the data display device refers to a display device having a display function, and particularly, the display device displays data having characteristics of relatively fixed content and long update period, which includes but is not limited to a transmission display type LED display screen (which may be referred to as a transmission display type LED display screen for short).
Step S100, when an uploading or configuration instruction aiming at target display data is received, based on the device identification information of the data display device and the target display data, and by using a target condition, generating first verification data associated with the data display device and the target display data.
In the embodiment of the application, the data display device provides a function of uploading or configuring display data, and an administrator can upload or configure the display data after passing the security identity authentication, wherein the display data includes but is not limited to video files, picture files or text information.
In the embodiment of the present application, the target display data does not refer to a fixed display data, but may refer to any display data uploaded or configured by an administrator.
When the data display device receives an upload or configuration instruction for target display data, the data display device may generate verification data (referred to as first verification data herein) associated with the data display device and the target display data by using a target condition based on the device identification information of the data display device and the target display data. In the embodiment of the present application, the uploading or configuring of the target display data may be understood as a time or a time period, and the time period may be any time period before the target display data is played, and the action of generating the verification data may be executed in the time period.
For example, the device identification information of the data display device may include, but is not limited to, one or more of CPU information, MAC (Media Access Control) network card information, and hard disk information of the data display device, which may uniquely identify the data display device.
For example, the preset algorithm in step S100 includes, but is not limited to, a digest algorithm (also referred to as a hash algorithm or a hash algorithm), a data signature algorithm, or the like; when the input parameters are the same, the output results calculated by the preset algorithm are the same; when the input parameters are different, the output results calculated by the preset algorithm are different, and the preset algorithm is a one-way algorithm.
For example, when the data display device generates the first verification data associated with the data display device and the target display data, the target display data and the generated first verification data may be saved respectively.
In one example, saving the first parity data may include:
and saving the first check data to a data safety area.
For example, in order to improve the security of the first verification data, when the data display device generates the first verification data, the first verification data may be saved in a preset data security area.
Illustratively, the data security zone may include, but is not limited to, an OTP (One Time Programmable) area, or a separate storage area where data is secured by encryption.
Step S110, when receiving a display data playing instruction, generating second verification data associated with the data display device and the display data to be played based on the device identification information and the display data to be played.
In the embodiment of the present application, the display data playing instruction may be triggered immediately or in a scheduled manner.
When the data display device receives the display data playing instruction, the data display device may generate verification data (referred to as second verification data herein) associated with the data display device and the display data to be played based on the device identification information of the data display device and the display data to be played.
In one example, the display data to be played may be locally saved display data.
For example, when the uploaded or configured target display data is received in step S100, the target display data may be saved, and when a display data playing instruction is received, the saved display data may be determined as display data to be played.
In another example, the display data to be played may be display data received in real time.
For example, when a display data playing instruction is sent to the data display device, the display data to be played may be sent to the data display device together, and when the data display device receives the display data playing instruction, the data display device may determine the received display data as the display data to be played.
It should be noted that, when the data display device generates the first check data and generates the second check data, the data display device needs to generate the first check data and the second check data under the same condition (which may be referred to as a target condition), for example, by using the same algorithm.
And step S120, comparing the first check data with the second check data. If yes, go to step S130; otherwise, go to step S140.
And step S130, playing the display data to be played.
Step S140, refusing to play the display data to be played.
In the embodiment of the application, it is considered that when the device identification information of the data display device for playing the display data or/and the display data to be played is tampered, the generated second verification data will be different from the first verification data based on the device identification of the device and the display data to be played.
Accordingly, after the data display device generates the second check data in the manner described in step S110, the second check data may be compared with the first check data generated in step S100.
And if the display data and the equipment identification information are the same, determining that the display data and the equipment identification information are not tampered, and playing the display data to be played by the data display equipment at the moment.
And if the display data and/or the equipment identification information are not the same, determining that the display data or/and the equipment identification information are tampered, and at the moment, refusing to play the display data to be played by the data display equipment, so that adverse effects caused by malicious display data playing are avoided.
It can be seen that, in the method flow shown in fig. 1, when display data is uploaded or configured, verification data is generated based on device identification information of the data display device and the uploaded or configured display data, and further, when display data needs to be played, the generated verification data is used to verify the device identification information and the display data to be played, and when the verification passes, the display data is played, and the display data and the data display device are bound by using the characteristics of fixed content and long update period of the display data played by the data display device, so that the specified display data is played on the specified data display device, and the accuracy and reliability of the display data played by the data display device are ensured.
In an alternative embodiment, referring to fig. 2, in step S100, generating first verification data associated with the data display device and the target display data based on the device identification information of the data display device and the target display data may be implemented by the following steps:
step S101, generating a first characteristic value based on the equipment identification information of the equipment.
And S102, generating first verification data based on the first characteristic value and the target display data.
For example, considering that the device identification information of the data display device is fixed and invariant, and the possibility that the device identification information is known by an illegal user is relatively high, in order to improve the reliability of the generated verification data, when the verification data is generated based on the device identification information and the display data, the device identification information may be processed first, for example, the device identification information is processed by using a specific algorithm, so as to reduce the possibility that the device identification information is known by the illegal user.
Accordingly, the data display device may generate a corresponding feature value (referred to herein as a first feature value) based on the device identification information of the device, and generate first verification data based on the first feature value and the target display data.
For example, the data display device may generate a first feature value using a first algorithm based on the device identification of the device, and generate second verification data using a second algorithm based on the first feature value and the target display data.
For example, the first algorithm and the second algorithm may be the same algorithm or different algorithms.
The first algorithm includes but is not limited to a digest algorithm or a data signature algorithm, etc.; when the input parameters are the same, the output results calculated by the first algorithm are the same; when the input parameters are different, the output results of calculation by using the first algorithm are different, and the first algorithm is a one-way algorithm.
Similarly, the second algorithm includes, but is not limited to, a digest algorithm or a data signature algorithm, etc.; when the input parameters are the same, the output results calculated by the second algorithm are the same; when the input parameters are different, the output results calculated by the second algorithm are different, and the second algorithm is a one-way algorithm.
In one example, the generating of the first verification data based on the first feature value and the target display data in step S102 may include:
and generating first verification data based on the first characteristic value, the target display data and the preset key.
For example, in order to further improve the reliability of the first verification data, when the first verification data is generated, the input parameter may include a preset key (referred to as a preset key herein) in addition to the first characteristic value and the target display data, that is, the data display device may generate the first verification data based on the first characteristic value, the target display data and the preset key.
As an optional embodiment, in an actual scene, there may be a case where an illegal user starts a new process in the data display device by means of trojan horse or the like to play the display data, so as to interfere with normal playing of the display data, and adds malicious data in the normal playing process of the display data, so that, in order to further improve the accuracy and reliability of the display data played by the data display device, the process information may also be used as an input parameter when generating the verification data.
In one example, referring to fig. 3, in step S102, generating first verification data based on the first feature value and the target display data may be implemented by:
and S1021, generating a second characteristic value based on the first characteristic value, the target display data and a preset key.
Step S1022 is generating a third feature value based on the progress information of the playback progress of the data display device.
Step S1023, generating first verification data based on the second feature value and the third feature value.
For example, to generate the first verification data, in one aspect, the data display device may generate a second characteristic value based on the first characteristic value, the target display data, and a preset key; on the other hand, a corresponding characteristic value (referred to as a third characteristic value herein) may be generated based on progress information (such as a progress name) of a playback progress (a progress for playing back display data, which may also be referred to as a host progress) of the data display apparatus.
Further, the data display device may generate the first verification data based on the second characteristic value and the third characteristic value.
It should be noted that, in this embodiment of the present application, specific implementation of generating, by the data display device, the second verification data based on the device identifier of the device and the display data to be played may refer to related implementation of generating the first verification data described in the foregoing embodiment, which is not described in detail in this embodiment of the present application.
As an optional embodiment, the verification is performed to avoid display data played by the display data during the playing of the display data by the data display device.
In one example, referring to fig. 4, after step S130, the following steps may be further included:
step S150, in the process of playing the display data by the data display device, generating third verification data associated with the data display device and the played display data based on the device identification information and the played display data at regular time.
Step S160, comparing the first verification data with the third verification data; and if the difference is not the same, controlling the data display equipment to stop playing the played display data.
For example, after the data display device plays the display data to be played, in the process of playing the display data, verification data (referred to as third verification data herein) associated with the data display device and the played display data may be generated based on the device identification information of the device and the played display data at regular time.
It should be noted that, in this embodiment of the present application, specific implementation of the data display device generating the third verification data based on the device identifier of the device and the played display data may refer to related implementation of generating the first verification data described in the foregoing embodiment, which is not described in detail in this embodiment of the present application.
When the data display device generates the third verification data, the third verification data and the first verification data may be compared.
If the two are different, the data display equipment is controlled to stop playing the played display data
If the two are the same, the playing of the display data is not changed.
It can be seen that, in the method flow shown in fig. 4, by verifying the device identification information and the display data during the display data playing process, it can be ensured that the playing can be stopped in time when the device identification information or/and the played display data are tampered, and the accuracy and reliability of the display data played by the data display device are further improved.
In an example, when the data display device determines that the first check data is different from the third check data, in addition to controlling the device to stop playing the played display data, the data display device may further perform an alarm process, such as sending an alarm message to a specified device by a wired network, a wireless network, or a mobile communication network, to prompt that the device has device identification information or/and a display data tampering event.
In order to enable those skilled in the art to better understand the technical solutions provided by the embodiments of the present application, the technical solutions provided by the embodiments of the present application are described below with reference to specific examples.

2. The main process generates a corresponding signature characteristic value (which may be referred to as a first signature characteristic value, i.e., the first check value) according to the process information of the main process, the device identification information of the transmission and display type LED display screen, and the display data.
For example, a specific generation flow of the signature feature value will be described below with reference to fig. 6, and details of the embodiment of the present application are not described herein.

4. And the main process detects a display data playing instruction.
5.

For example, when the main process determines that the second signature characteristic value is different from the first signature characteristic value, the main process may further perform alarm processing, and specific implementation thereof is not described herein again.
6. When the transmission and display type LED display screen system is started, a daemon process can be started, and the daemon process runs until the system is closed. In the process of playing the display data, the daemon process may generate a signature characteristic value (which may be referred to as a third signature characteristic value, i.e., the third verification value) in the manner in step 2 based on the process information of the host process, the device identification information, and the played display data at regular time, and compare the third signature characteristic value with the first signature characteristic value stored in the data security region, and if the third signature characteristic value is not consistent with the first signature characteristic value stored in the data security region, control the host process to stop playing the display data, and perform alarm processing.

2. the pre-stored watermark key (i.e. the above-mentioned preset key) is obtained from the data security zone.
Illustratively, the watermark key is a secure random number, and is stored in the data security area.

4. The process data feature value (i.e., the third feature value) is generated by using a digest algorithm based on the process information (e.g., the process name) of the host process.
5. Signature feature values (which may also be referred to as process and display data signature feature values) are generated using a digest algorithm based on the display data feature values and the process data feature values.
