In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.

In order to improve the problem of poor video playing security caused by the fact that the video clip is not encrypted in the playing flow of the member video in the related art. The video playing method is safer, protected and high in quality, and ensures the safety of video playing, so that benefits of member video providers are protected, and better user experience is provided.

The video playing method provided by the disclosure is mainly applied to the intelligent terminal, can be particularly applied to video playing scenes in the intelligent terminal, can be particularly applied to scenes such as entertainment, education, news media and the like, and is not limited in the embodiment of the disclosure.

The video playing method provided by the present disclosure is described in detail below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a video playing method according to an embodiment of the present disclosure. As shown in fig. 1, the method is applied to a server, and the video playing method includes steps 101-104.

Step 101, responding to a video playing request sent by a client through a video playing interface, and checking a user login state and a user identity state of the client.

In the embodiment of the disclosure, the video playing interface is a network interface, which is acquired by the client through a video playing page triggered by a user and is used for realizing interaction between the client and the server. The video playing interfaces corresponding to different video playing pages may be the same or different, which is not limited in the embodiments of the present disclosure.

The video playing request refers to a request sent by a client to a server, and is used for requesting to play a video file or streaming media data.

The checking of the user login status and the user identity status of the client may be performed by a video playing service in the server. The user login state includes a logged-in state and a non-logged-in state, and the user identity state includes a member state and a non-member state.

Specifically, after receiving a video playing request sent by a client through a video playing interface, the video playing service of the server can check the user login state and the user identity state of the client so as to perform subsequent operations of video playing according to the user login state and the user identity state.

It can be understood that by checking the user login status and the user identity status of the client, it can be ensured that only logged in and qualified users can play the encrypted video file, thereby protecting the security of the video content and the rights and interests of authorized users.

Step 102, if the user login state is the logged-in state, processing the encrypted video file, and sending the processed complete video file to the client.

In the present disclosure, an encrypted video file is obtained by segment-encrypting a video file in a first format, which is obtained by transcoding a video file in an original format, and the encrypted video file includes a text playlist and a plurality of video clips corresponding to the text playlist.

In the embodiment of the disclosure, if the video playing service of the server detects that the user login state is the logged-in state, the encrypted video file is processed to obtain the processed complete video file. And sends the complete video file to the client.

The complete video file also comprises a determined key address and a token generated based on the token request of the client.

Step 103, in response to the token verification request sent by the client through the key address in the complete video file, verifying whether the token in the complete video file is valid.

In the disclosed embodiment, the key address refers to an interface address of the video key service, and the token verification request refers to a request for the video token service of the server to verify whether the token in the current complete video file is valid.

The Token may also be called Token, and in the application of video playing, the Token is a string of characters generated by the video Token service of the server, and may be used as a Token requested by the client. When the user logs in for the first time, the video Token service of the server generates a Token and returns the Token to the client. After that, the client only needs to carry the Token to request data, and does not need to carry the user name and the password again. Token's composition typically includes a user's unique identity, validity time, and signature (i.e., the first few bits of Token are compressed into a length of hexadecimal string by a hash algorithm).

In the present disclosure, the video token service of the server may specifically verify whether the current token is valid according to the validity time of the token.

Step 104, if the token is valid and the user identity state is a member state, acquiring a key of a storage device pre-stored in the server, and sending the key to the client through a key address, so that the client decrypts the complete video file through the key and plays a plurality of video clips in the complete video file.

In the embodiment of the disclosure, if the current token is verified to be valid according to the valid time of the token and the current user identity state is a member state, a key pre-stored in a storage device of a server is acquired and sent to a client through a key address.

The storage device of the server may refer to a cloud disk of the server. Yun Pan is a specialized internet storage tool, is a product of internet cloud technology, provides services such as information storage, reading and downloading for enterprises and individuals through the internet, and has the characteristics of safety, stability and mass storage. The cloud disk is used on the server, so that the data can be stored and managed more conveniently, and meanwhile, the safety and reliability of the data can be improved.

In summary, by the method provided by the present disclosure, the video file may be encrypted in segments, and a detection mechanism for a user login state and an identity state and a token verification mechanism are set, so that only an authorized user is ensured to play the video file, interception, downloading or pirating of content by an unauthorized user is avoided, and maintenance of copyright of the content is facilitated, thereby protecting security of the video content and rights of the authorized user, and ensuring that a content provider can reclaim creation and investment of the content provider.

Based on the embodiment shown in fig. 1, fig. 2 further shows a flow chart of a video playing method proposed in the present disclosure. Fig. 2 further defines steps 102 and 103 based on the embodiment shown in fig. 1. In the embodiment shown in fig. 2, step 102 includes step 202, step 203, and step 204, and step 103 includes step 205. As shown in fig. 2, the method comprises the steps of:

step 201, responding to a video playing request sent by a client through a video playing interface, and checking a user login state and a user identity state of the client.

In an embodiment of the present disclosure, a user login identifier and a user identity identifier of a client are obtained; respectively inquiring a user identification list pre-stored in a database according to the user login identification and the user identification; if the user login identification or the user identity identification is inquired in the user identity list, determining that the user login state is a logged-in state or the user identity state is a member state; if the user login identification or the user identity identification is not queried in the user identity list, determining that the user login state is an unregistered state or the user identity state is a non-member state.

In an optional embodiment of the present disclosure, the client may obtain, through a video playing page triggered by a user, an address of a video playing interface corresponding to a current food playing page. The client accesses the video playing interface through the address of the food playing interface and sends a video playing request to the video playing service of the server. And responding to the video playing request, the video playing service of the server acquires the user login identification and the user identity identification of the current client, queries a user identification list stored in a database, and determines the user login state and the user identity state of the current client according to the query result.

Step 202, if the user login state is the logged-in state, generating a token in response to the token request of the client.

In an embodiment of the present disclosure, if a video playback service in a server checks that a user login state is a logged-in state, a video token service of the server generates a token in response to a token request sent by a client.

Optionally, before step 202, the method further includes: receiving a video file in an original format, and triggering a transcoding task; transcoding the video file in the original format based on a transcoding command in the transcoding task to generate a video file in a first format; the method comprises the steps of carrying out segmented encryption on a video file in a first format through a secret key and an encryption algorithm, obtaining an encrypted video file, storing the encrypted video file into a storage device of a server, and obtaining the secret key under a transcoding task according to the encryption algorithm.

The method comprises the steps of encrypting a video file in a first format through a secret key and an encryption algorithm, obtaining an encrypted video file, and storing the encrypted video file into a storage device of a server, wherein the method comprises the following steps: and adding a preset label to the text play list in the video file in the first format, wherein the preset label comprises an encryption algorithm and a key address.

Specifically, in an alternative embodiment of the present disclosure, as shown in the schematic diagram of video encryption transcoding in fig. 3, a video provider uploads a video in a raw format to a video transcoding service of a server. Wherein the original format may be an mp4 format. A video provider refers to a content creator, media agency, individual user, or other entity that owns a video asset.

And triggering a transcoding task after the video transcoding service receives the video file in the original format, and requesting the video key service of the server to generate a key. The video key service generates a key according to an encryption algorithm and stores the corresponding relation among the video identification, the key identification and the key ciphertext. The encryption algorithm may be an AES encryption algorithm, and the key may be a random 128-bit AES key generated by the AES encryption algorithm.

The video transcoding service transcodes the video file in the original format to generate a video file in a first format, wherein the video file in the first format comprises a text play list and a plurality of video clips corresponding to the text play list. The first format may be M3U8 format, the text playlist may be a header of a video file in M3U8 format, and the plurality of video clips may be TS video clips.

The video key service uses the generated key to encrypt the video file in the first format in a segmented way to obtain an encrypted video file, and stores the encrypted video file to a cloud disk, namely a storage device of the server.

It should be noted that, before the encrypted video file is obtained, a preset tag (for example, "#ext-X-KEY" tag) may be added to the video file in the first format after the transcoding is completed, where the preset tag includes an encryption algorithm and a KEY address. I.e. the preset tag contains an encryption algorithm attribute ("METHOD" attribute) which may be designated as AES-128, and a key address attribute ("URI" attribute) which is the key address of the video key service.

Wherein M3U8 is a Unicode version of M3U encoded with UTF-8. Both the "M3U" and "M3U8" files are the basis for the HTTP Live Streaming (HLS) protocol format used by apple inc, which can be played on devices such as iPhone and Macbook.

The TS (Transport Stream) is a packaged format, which is all called MPEG2-TS. MPEG2-TS is a standard data container format for transmitting and storing audio and video, program and system information protocol data, and is mainly used in digital broadcasting systems such as DVB, ATSC and IPTV. Transport streams were originally designed for broadcast. Later, by adding 4-byte Time Code (TC) to standard 188-byte data packet, the data packet is converted into 192-byte data packet, and the 192-byte data packet is suitable for digital video cameras, video recorders and players

The advanced encryption standard (Advanced Encryption Standard, AES), also known as Rijndael encryption, in AES cryptography is a block encryption standard adopted by the federal government in the united states.

In addition, in the embodiment of the disclosure, if the login state is the unregistered state, a part of the video file of the encrypted video file is intercepted and sent to the client.

Specifically, if the login state is an unregistered state or the user identity state is a non-member state, a part of video file with a preset size is intercepted according to the video file with the current first format, and the part of video file is sent to the client, so that the client can directly play the part of video file. The preset size may be determined according to practical situations, and is not limited in the embodiments of the present disclosure.

Step 203, determining a key address in a preset tag in the encrypted video file, and adding the token to the encrypted video file to obtain a complete video file.

In the embodiment of the present disclosure, the KEY address ("URI" address) in the preset tag ("#ext-X-KEY" tag) is modified, so as to determine the KEY address in the preset tag in the current encrypted video file, and the token acquired in step 202 is added to the encrypted video file, so as to acquire the complete video file.

And step 204, transmitting the complete video file to the client.

In the embodiment of the present disclosure, the complete video file obtained in step 203 is sent to the client through the video playing interface.

Step 205, in response to the token verification request sent by the client through the key address, verifying whether the token is valid or not according to the valid time of the token.

In an embodiment of the disclosure, if the current time does not exceed the valid time of the token, determining that the token is valid; and if the current time exceeds the valid time of the token, determining that the token is invalid.

In an alternative embodiment of the present disclosure, a token authentication request sent by a client via a key address is received and in response to the token authentication request, it is verified whether the token is valid. The method specifically comprises the steps of comparing the current time with the effective time of the current token by acquiring the current time and the effective time of the current token, and determining that the token is effective if the current time does not exceed the effective time; if the current time exceeds the valid time of the token, then the token is determined to be invalid.

Step 206, if the token is valid and the user identity state is a member state, acquiring a key of a storage device pre-stored in the server, and sending the key to the client through a key address, so that the client decrypts the complete video file through the key and plays a plurality of video clips in the complete video file.

In the embodiment of the disclosure, if the token is valid and the checked user identity state is a member state, a key stored in the server cloud disk is queried and sent to the client, so that the client decrypts the encrypted video file through the key and plays the video clip in the encrypted video file.

In addition, in the embodiment of the disclosure, if the token is invalid or the checked user identity state is not the non-membership state, a verification error message is returned to the client at this time.

In summary, the present disclosure uses HLS encryption to ensure that member video content is effectively cryptographically protected, helping to maintain privacy rights for users, ensuring that only authorized members can access the content. Unauthorized users are prevented from intercepting, downloading or pirating the content, which is helpful for maintaining the copyright of the content, ensuring that the content provider can reclaim the creation and investment of the content provider, and protecting the rights and interests of members and the income sources of the content provider. Meanwhile, the video playing method can use the HTTPS protocol to transmit the encrypted video content and the secret key, so that the safety of data in the transmission process is ensured. This prevents data leakage and tampering, protecting the integrity of the user data. And the video playing method has wide compatibility, can play the encrypted video stream on various devices and operating systems, which means that members can watch contents on the devices selected by the members, and provides greater flexibility.

Fig. 4 is a flowchart of a video playing method according to an embodiment of the present disclosure. As shown in fig. 4, the method is applied to a client, and the video playing method includes steps 301 to 304.

Step 301, responding to a video playing page triggered by a user, and acquiring a video playing interface address corresponding to the video playing page.

Step 302, a video playing request is sent to a server through a video playing interface, and a complete video file sent by the server when the user login state is the logged-in state is received.

In step 303, the player of the client sends a token verification request to the server through a key address, so that the server verifies whether the token in the complete video file is valid, and the key address is obtained by analyzing the complete video file through the player.

In the embodiment of the disclosure, after receiving the complete video file sent by the server, the client sends the complete video file to the player, and the player obtains a key address by analyzing the complete video file and sends a token verification request to the server according to the key address.

Step 304, receiving the key sent by the server when the user identity state is the member state and the server verifies that the token is valid, and decrypting the complete video file through the key to play a plurality of video clips in the complete video file.

In summary, by the method provided by the present disclosure, the video file encrypted in segments can be decrypted and played, and a detection mechanism and a token verification mechanism for the user login state and the identity state are set, so that only authorized users can play the video file, unauthorized users are prevented from intercepting, downloading or pirating the content, copyright of the content is maintained, safety of the video content and rights of authorized users are protected, and content providers can be ensured to reclaim creation and investment.

If the user login state is the unregistered state or the user identity state is the non-membership state, part of the video files in the complete video files are intercepted as file resources of the trial viewing M3U8 and sent to the client.

If the user login state is the login state and the user identity state is the member state, a video token service (video token service) of the request server acquires a token (token), determines a key address ('URI' address) in an encrypted video file (complete m3u8 file resource), adds the token into the encrypted video file, acquires a complete video file, and sends the complete video file to the client;

after the client acquires the complete video file, the complete video file is transmitted to a player of the client, the player analyzes the complete video file after receiving the complete video file, acquires a key address in a preset tag in the complete video file, and requests the server to send a key according to the key address.

After receiving the key request through the key interface corresponding to the key address, the video key service in the server requests the video token service to verify whether the token is valid. If the token is invalid or the user identity state is a non-member state, returning verification error information to the client; if the token is valid and the user identity state is a member state, inquiring a corresponding key, and sending the key to the client for decrypting the complete video file and playing the video clip in the complete video file.
