Embodiment 1

[0072] The embodiment of the present invention provides a recording and broadcasting data processing method, which is applied in the transmission process of recording and broadcasting data, such as figure 1 shown, including the following steps:

[0073] Step S11, the recording server receives the playback request from the client.

[0074] Generally, the server database corresponding to the recording and broadcasting server stores a large amount of multimedia data and encryption keys corresponding to the multimedia data, and also stores data information such as file size, modification time, and data format corresponding to the multimedia data. When the client needs to play some multimedia data, it only needs to send a playback request to the recording server.

[0075] Step S12, the recording and broadcasting server determines the multimedia data and its corresponding encryption key requested by the client according to the playback request, wherein the multimedia data stored by...

Embodiment 2

[0106] An embodiment of the present invention provides a recording and broadcasting data processing device, such as Figure 4 As shown, it includes a receiving unit 21 , a determining unit 22 , a calling unit 23 and a first sending unit 24 . in,

[0107] The receiving unit 21 is arranged on the recording and broadcasting server, and is used for receiving the playback request of the client;

[0108] The determination unit 22 is arranged on the recording server, and is used to determine the multimedia data requested by the client and its corresponding encryption key according to the playback request, wherein the multimedia data stored by the recording server is ciphertext encrypted by a cryptographic device data, and the corresponding encryption key is the ciphertext key encrypted by the cryptographic device;

[0109] The calling unit 23 is used to call the cryptographic device, and utilize the cryptographic device to perform secondary processing on the multimedia data request...

Embodiment 3

[0129] The embodiment of the present invention provides a specific example of the above recording and broadcasting data processing method, including the following steps:

[0130] (1) Data upload (see Figure 6 )

[0131] 1. The multimedia data source transmits the multimedia data to the recording and broadcasting server;

[0132] 2. The recording and broadcasting server requests the cryptographic device to generate a symmetric key Key, and uses the Key to encrypt the multimedia data to obtain the ciphertext data EncData. At the same time, use the identification IDs of the recording server, run the SM9 encryption algorithm, encrypt the Key, and obtain the ciphertext symmetric key EncKey. The encryption device returns EncData and EncKey to the recording server.

[0133] 3. The recording and broadcasting server stores EncKey and file information in the database, and saves EncData to the storage medium, wherein the file information includes general information such as file size...

Abstract

The present invention relates to the technical field of recording and broadcasting, and discloses a recording and broadcasting data processing method and device. The method comprises the steps that: arecording and broadcasting server receives a play request of a client; the recording and broadcasting server determine multimedia data required by the client and corresponding encryption keys according to the broadcasting request, wherein the multimedia data stored in the recording and broadcasting server are ciphertext data after encryption processing by a password device, and the correspondingencryption keys are ciphertext secret keys after encryption processing by the password device; the recording and broadcasting server transfers the password device, employs the password device to perform secondary processing of the multimedia data required by the client and the corresponding encryption keys and obtains the multimedia data and the corresponding encryption keys after secondary processing; the recording and broadcasting server sends the multimedia data after secondary processing to the client. In the recording and broadcasting data transmission process, the plaintext is not fell to ensure the safety of the recording and broadcasting data in the transmission process and be not easy to be attacked by an intermediary.

Description

technical field [0001] The invention relates to the technical field of recording and broadcasting, in particular to a recording and broadcasting data processing method and device. Background technique [0002] Recording and broadcasting is to record the lecture or speaker's influence, sound and lecture notes into a standard network format in the form of hardware equipment in real time, and broadcast live simultaneously through the network and server, or save the content in the storage medium of the server after the lecture is over. In order to meet the user's subsequent requirements for obtaining and replaying from the storage medium of the server. [0003] With the continuous development of science and technology, recording and broadcasting technology has been widely used in the field of video conferencing. At present, recorded multimedia data is generally stored and transmitted in the following ways: 1. Use plain text to store multimedia data, and also use plain text to t...
