The method comprises the steps that when a new process is detected to be created by a terminal device in the playing process of target multimedia data, first process information corresponding to the newly created target process is obtained and sent to a server, wherein when the server determines that the target process is a screen recording process according to the first process information, a screen recording preventing control instruction is sent to the terminal device, the screen recording preventing control instruction is received, and screen recording preventing actions corresponding to the screen recording preventing control instruction are executed. The method realizes that the new process which is detected and created in the playing process is a screen recording process, and the playing of the target multimedia data is stopped. The target multimedia data is prevented from being privately recorded by a screen recording application installed on the terminal equipment in the playing process of the user, and leakage of the target multimedia data is avoided.
Referring to fig. 2, in an embodiment, the control method of the stylus includes the following steps:
step S10, when a new process is detected to be created by the terminal equipment in the playing process of the target multimedia data, first process information corresponding to the newly created target process is obtained;
in the prior art, in the process of playing a program by a terminal device, whether a user starts a screen recording program or not cannot be detected in time, so that the program content played by the terminal device is recorded.
In the application, the terminal equipment comprises equipment such as a computer, a notebook computer, a mobile terminal and the like which can be provided with a screen recording program to record the currently played multimedia data. In this embodiment, a mobile terminal (mobile phone) is taken as an example of the terminal device.
The target multimedia data is multimedia data of prohibiting recording during playing. It may be all multimedia data in the playback program, for example, only the viewing rights in the playback program are provided, multimedia data that is prohibited from being downloaded, spread in any way, or the target multimedia data may be the multimedia data that is obtained viewing rights after payment but not have been spread by downloading, recording, or the like.
In this embodiment, the method for 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 a new created process in a playing process of playing the multimedia data, and when determining that the terminal device has a new created process, take the new created process as a target process, and obtain first process information corresponding to the target process.
For example, when the mobile phone plays the target multimedia data (the "redemption of the Showcase") and the user starts other application programs (e.g., weChat), the extension plug-in installed in the mobile phone determines that a new process is currently created through the API interface.
It can be understood that in this embodiment, when the user starts the playing program, the playing program first determines whether the extension plug-in is installed in the current terminal device, and when it is determined that the extension plug-in is not installed in the terminal device, sends out a prompt message of "please install the extension plug-in for preventing recording" in the terminal device, and provides website information for downloading the extension plug-in a display interface of the playing program.
Step S20, the first process information is sent to a server, wherein when the server determines that the target process is a screen recording process according to the first process information, an anti-screen recording control instruction is sent to the terminal equipment;
When the creation of a new process is detected in the playing process of the target multimedia data, the creation of the new process is used as a target process, and first process information corresponding to the target process is acquired. The expansion plug-in obtains a target process by detecting a newly started application program in the terminal equipment, and further obtains first process information of the target process. The information tuples of the processes are { program name, process name, operation platform }, and the process information sent to the server is information obtained by encoding the processes through JSON. The format of the Json code is as follows: [ { "Program": string, "Process": string, "Platform": string } ].
For example, an application program started by a user in the process of playing target multimedia data is WeChat and KK screen recording, an expansion plug-in determines that a new process is created by a terminal device and is used as a target process, an information tuple of the target process is { WeChat, exe, windows8}, { KK video recorder, KK, exe, windows8}, and the first process information of the target process is:
[{
"Program": "WeChat",
"Process":"WeChat.exe",
"Platform":"Windows8"
},{
"Program": "KK screen",
"Process":"KK.exe",
"Platform":"Windows8"
}]
and sending the obtained first process information to a server. Therefore, after the server receives the first process information, the server determines whether the newly created target process of the terminal equipment is a screen recording process 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 equipment.
Optionally, after the server receives the process information, the received process information is compared with stored preset process information, wherein the preset process information is process information of a screen recording process acquired through the crawler module. 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; if the comparison fails, confirming that the screen recording process does not exist in the target process. And finally, sending corresponding instructions (an anti-screen recording 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 because the screen recording process exists in the process that the terminal equipment cannot be accurately detected due to connection faults is avoided.
Step S30, receiving the anti-recording control instruction and executing the anti-recording action corresponding to the anti-recording control instruction.
When the terminal equipment receives that the target process confirmed by the server is a screen recording process, the terminal equipment is controlled to stop playing the target multimedia data.
Specifically, this embodiment may be exemplified by that, in the process that the terminal device plays the movie "shoshenke's redemption (target multimedia data), when detecting that the user clicks the application installed in the terminal device to be a kk screen, a new process is created by the terminal device through detecting by the extension plug-in, and the new process is taken as the target process. Further, the information tuple taking the KK screen recording process as the target process is { KK video recorder, KK. Exe, windows8}, and the corresponding first process information is:
{
"Program": "KK screen",
"Process":"KK.exe",
"Platform":"Windows8"
}
and sending the process information corresponding to the target process to a server, and after the server receives the process information, comparing the process information with stored preset 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 an anti-screen-recording control instruction to the terminal equipment.
After receiving the anti-recording control instruction sent by the server, the terminal equipment pauses playing the target multimedia data, and displays the prompt message of 'currently playing content system recording on the display interface', so as to prompt the user to close the KK recording program.
Optionally, in this embodiment, when the user clicks the multimedia data to play, the process running in the current terminal device may be obtained, and further the process information is sent to the server, and the server determines, according to the received process information, whether a screen recording process exists in the process running in the current terminal device, and feeds back a confirmation result. And when the terminal equipment receives the confirmation result fed back by the server and the screen recording process does not exist, starting to play the target multimedia data. And when the new process is detected in the playing process, the process is used as a target process, and the process information of the target process is sent to the server for confirmation. Before playing, the security of the playing environment of the terminal equipment is determined, so that the security of the target multimedia data is improved.
In this embodiment, when it is detected that a new process is created by a terminal device during playing of target multimedia data, first process information corresponding to the newly created target process is obtained, and the first process information is sent to a server, where when the server determines that the target process is a screen recording process according to the first process information, the server sends a screen recording preventing control instruction to the terminal device, receives the screen recording preventing control instruction, and executes a screen recording preventing action corresponding to the screen recording preventing control instruction. The method and the device realize that whether the created new process is a screen recording process is detected in the playing process, and play is stopped when the new process is determined to be the screen recording process. The target multimedia data is prevented from being privately recorded by a screen recording application installed on the terminal equipment in the playing process of the user, and leakage of the target multimedia data is avoided.
