Problems solved by technology

This method has the following problems: the password is fixed, and in order to ensure its security, it needs to be changed regularly. After changing the password, the client user needs to be notified manually, which is inconvenient to operate and has potential safety hazards.
Since the data is in plain text, as long as you get the data stream or file, you can play it through the player, which will lead to illegal access to sensitive data

Embodiment 1

[0029] Embodiment 1: the present invention proposes a kind of video data safe encrypted transmission method, it is characterized in that, comprises steps:

[0030] S1. The streaming media server randomly generates a first password, and uses the first password to encrypt key frames of video data to obtain a first encrypted key frame;

[0031] Encrypting only key frames reduces the workload of encryption, and videos without key frames cannot be played, and good encryption effects can still be achieved.

[0032] S2. The streaming media server uses a hardware encryption lock to encrypt the first password to obtain a first password encrypted file, uses a hardware encryption lock to encrypt the first encrypted key frame to obtain a second encrypted key frame, and the transmission includes the second encrypted key frame, The first password encrypts the file, uses the first password to encrypt the key frame of the video data to obtain the video data of the encryption algorithm algorit...

Embodiment 2

[0041] Embodiment 2: the present invention also provides a kind of video data safe encryption transmission system, comprises following unit:

[0042] The first encryption unit 100 for the streaming media server side to randomly generate the first password, and use the first password to encrypt the key frame of the video data to obtain the first encrypted key frame;

[0043]Encrypting only key frames reduces the workload of encryption, and videos without key frames cannot be played, and good encryption effects can still be obtained.

[0044] The second encryption unit 200 is used for the streaming media server to encrypt the first password to obtain the first password encrypted file by using the hardware dongle 600 , and to encrypt the first encrypted key frame by using the hardware dongle 600 to obtain the second encrypted key frame.

[0045] Using hardware encryption for the first encrypted key frame and the first password increases the security of the system. The random pas...

Abstract

The invention provides a video data security encryption transmission method. The video data security encryption transmission method is characterized by comprising the following steps: S1, a streaming media server randomly generates a first password, and encrypts a key frame of video data by using the first password to obtain a first encrypted key frame; and S2, the streaming media server encrypts the first password by using a hardware encryption lock to obtain a first password encrypted file, encrypts the first encrypted key frame by using the hardware encryption lock to obtain a second encrypted key frame, encrypts the key frame of the video data by using the second encrypted key frame, the first password encrypted file and the first password to obtain the video data of algorithm type information of an encryption algorithm of the first encrypted key frame. The video data security encryption transmission method provided by the invention has the beneficial effects that the first password is randomly generated and is periodically updated to ensure the security. By means of the hardware encryption of the random password, and the software encryption and the hardware encryption of the video data, the security is higher.

Description

technical field [0001] The invention relates to a data transmission method and system, in particular to a video data secure encryption transmission method and system. Background technique [0002] The existing streaming media server software uses a manually set password to encrypt and transmit video data when transmitting video data. When the video needs to be played on the client software, the password needs to be manually entered, and the real-time video stream or playback is played after the verification is passed. Historical footage. This method has the following problems: the password is fixed, and it needs to be changed regularly to ensure its security. After changing the password, the client user needs to be notified manually, which is inconvenient to operate and has potential safety hazards. [0003] The existing technology adopts the method of manually recording the historical password and the corresponding historical video file, and the historical video file c...
