The method and the device realize that the created new process is detected to be a screen recording process in the playing process, and the target multimedia data is stopped to be played. The method and the device prevent a user from privately recording the target multimedia data through the recording screen application installed on the terminal device in the playing process, and avoid leakage of the target multimedia data.
Referring to fig. 2, in an embodiment, the method for controlling the touch and talk pen includes the following steps:
step S10, in the playing process of the target multimedia data, when detecting that the terminal device creates a new process, acquiring first process information corresponding to the newly created target process;
in the prior art, in the process of playing a program by a terminal device, whether a user starts a screen recording program cannot be detected in time, so that the content of the program played by the terminal device is recorded.
The terminal equipment in the application comprises equipment such as a computer, a notebook computer and a mobile terminal, wherein the equipment can be used for installing a screen recording program to record the screen of the currently played multimedia data. In this embodiment, the terminal device is described by taking a mobile terminal (mobile phone) as an example.
The target multimedia data is the multimedia data of which the screen recording is forbidden in the playing process. It may be all multimedia data in the playing program, for example, multimedia data that is only provided with the viewing right in the playing program and is prohibited from being downloaded and propagated in any way, or the target multimedia data may be multimedia data that has obtained the viewing right after paying but has not been propagated by downloading, screen recording and the like.
In this embodiment, the manner of detecting that the terminal device creates the new process may determine, through an extension plug-in installed in the terminal device, whether the terminal device has the newly created process in the playing process of playing the multimedia data, and when it is determined that the newly created process exists in the terminal device, the newly created process is used as a target process, and first process information corresponding to the target process is obtained.
For example, when the mobile phone plays targeted multimedia data (the "Shouchuke's redemption"), and the user launches other applications (e.g., WeChat), the extension plug-in installed on the mobile phone determines through the API interface that a new process is currently being created.
It can be understood that, in this embodiment, when the user starts the playback program, the playback program first determines whether the current terminal device has installed the extension plug-in, and when it is determined that the terminal device has not installed the extension plug-in, sends a prompt message "please install the extension plug-in for preventing screen recording" in the terminal device, and provides the website information for downloading the extension plug-in the display interface of the playback program.
Step S20, sending the first process information to a server, wherein the server sends a screen recording prevention control instruction to the terminal equipment when determining that the target process is a screen recording process according to the first process information;
when the creation of a new process is detected in the playing process of the target multimedia data, the created new process is used as a target process, and first process information corresponding to the target process is obtained. The extension plug-in obtains the target process by detecting the newly started application program in the terminal equipment, and further obtains first process information of the target process. The information tuple of the process is { program name, process name, running platform }, and the process information sent to the server is information obtained by encoding the process through JSON. The format of the Json code is as follows: [ { "Program": String, "Process": String), "Platform": String },.
For example, the application program started by the user in the process of playing the target multimedia data is WeChat and KK screen recording, the extension plug-in determines that the terminal device creates a new process, and takes the new process as a target process, and the information tuple of the target process is { WeChat.exe, Windows8}, { KK video recorder, KK.exe, Windows8}, then the first process information of the target process is:
[{
"Program": minute letter ",
"Process":"WeChat.exe",
"Platform":"Windows8"
},{
"Program": KK recording screen ",
"Process":"KK.exe",
"Platform":"Windows8"
}]
and sending the obtained first process information to a server. Therefore, after the server side receives the first process information, whether a newly created target process of the terminal device is a screen recording process or not is determined according to the first process information, and when the target process is determined to be the screen recording process, a screen recording prevention control instruction is sent to the terminal device.
Optionally, after receiving the process information at the server, the server compares the received process information with stored preset process information, where the preset process information is the process information of the screen recording process acquired by the crawler module. And the server compares the preset process information with the received first process information. If the comparison is successful, determining that the target process is a screen recording process; and if the comparison fails, confirming that the screen recording process does not exist in the target process. And finally, sending corresponding instructions (a screen recording prevention control instruction and a playing environment safety instruction) to the terminal equipment.
Optionally, in this embodiment, before the terminal device sends the first process information to the server, the terminal device establishes a connection with the server, so as to implement normal communication between the terminal device and the server, so as to send the first process information to the server. The problem that the target multimedia data is recorded due to the fact that a screen recording process exists in the process that the starting of the terminal equipment cannot be accurately detected due to the connection fault is solved.
And step S30, receiving the screen recording prevention control instruction, and executing a screen recording prevention action corresponding to the screen recording prevention control instruction.
And when the terminal equipment receives that the target process confirmed by the server is a screen recording process, controlling the terminal equipment to stop playing the target multimedia data.
Specifically, in the embodiment, for example, in the process of playing the movie "the redemption of xiaoshen" (target multimedia data) by the terminal device, when detecting that the user records the screen for kk by clicking the application installed in the terminal device, the new process created by the terminal device is obtained by detecting the extended plug-in, and the new process is used as the target process. Further, an information tuple using the KK screen recording process as a target process is { KK video recorder, kk.exe, Windows8}, and corresponding first process information is:
{
"Program": KK recording screen ",
"Process":"KK.exe",
"Platform":"Windows8"
}
and sending the process information corresponding to the target process to a server, comparing the process information with the stored preset process information after the server receives the process information, and determining that the target process acquired in the playing process is a screen recording process when the comparison is successful. And sending a screen recording prevention control instruction to the terminal equipment.
And after the terminal equipment receives a screen recording prevention control instruction sent by the server, pausing playing of the target multimedia data and displaying prompting information of 'currently played content system recording screen' on a display interface so as to prompt a user to close the KK screen recording program.
Optionally, in this embodiment, the process currently running by the terminal device may be obtained when the user clicks the multimedia data for playing, and then the process information is sent to the server, and the server determines whether a screen recording process exists in the process currently running by the terminal device according to the received process information, and feeds back a confirmation result. And when the terminal equipment receives the confirmation result fed back by the server that the screen recording process does not exist, starting to play the target multimedia data. And when detecting that a new process exists in the playing process, the process is taken as a target process, and the obtained process information of the target process is sent to the server for confirmation.
