According to the method for setting the video playback permission and verifying the video playback permission, the application provides a preferred embodiment.
In a family, a camera 1 of a parent bedroom is connected to a video channel 1 of a video recording device, a camera 2 of a child room is connected to a video channel 2 of the video recording device, a parent account admin and a child account lily are respectively added to the video recording device, the account admin has the playback permission of the video channel 1, and the account lily has the playback permission of the video channel 2, so that the parent and the child can only view videos of the cameras in the rooms. Supposing that after a period of time, a hardware fault occurs in a video channel 1 of the video recording device, the parent camera 1 is switched to a video channel 2 of the video recording device, and the child camera is switched to a video channel 3, at this time, it is necessary to open the playback permission of the video channel 2 to the account admin, open the playback permission of the video channel 3 to the account lily, and close the playback permission of the video channel 2 to the account lily, after the video channel is switched, although the playback permission of the video channel 2 is opened by the account admin, no account admin exists in the permission index information of the history video file before the switching of the video channel 2, so that the switched account admin cannot play back the video file before the switching of the child room camera, and the privacy of the child can be well protected. Similarly, the account lily is stored in the history video file of the children room camera, so that even if the account lily of the children does not have the playback permission of the video channel 2 after the video channel is switched, the history video file of the children room camera 2 before the switching can be played back, and the problem that the history video permission cannot be effectively controlled after the video channel is switched in the using process of the camera is solved.
Further, in the case where the hard disk of the video recording apparatus 1 is removed and installed in the video recording apparatus 2, even if the account of the video recording apparatus 2 has playback rights of all channels, since the account, the playback password, and the login password on the video recording apparatus 2 are not included in the video recording file header rights index information on the hard disk, the video recording file on the hard disk cannot be played back on the video recording apparatus 2. Even if the video recording device 2 has the same account and the same first login password as those of the video recording device 1, since the serial number of the device is increased when the login password is calculated by using the MD5 on a different device, the correct login password cannot be calculated on the video recording device 2, and the video recording in the hard disk is effectively prevented from being illegally accessed.
In the method described in the application, the video files stored in the hard disk also include the authority index information in the index area in the video file header and the password information in the password storage space, and because the special file system cannot be read and modified in the third-party equipment, the problem that the authority index information and the password information of the hard disk video files are modified in the third-party equipment to obtain the video playback authority does not exist.
