In the technical solution provided in the embodiment of the present application, a device for implementing a function of a terminal device is a terminal device, and the terminal device is a mobile phone, for example, the technical solution provided in the embodiment of the present application is described.
In addition, in the scenario shown in fig. 1, the terminal device 2 may also access the internet 3 through an access network device, which is not shown in the figure. The access network devices include, but are not limited to: next generation base station (gbb) in 5G, evolved node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), home base station (e.g., home evolved node B, or home node B, HNB), Base Band Unit (BBU), transmission point (TRP), Transmission Point (TP), mobile switching center, base station in future mobile communication system, or access point in WiFi system, etc. The access network device may also be a wireless controller, a Centralized Unit (CU), and/or a Distributed Unit (DU) in a Cloud Radio Access Network (CRAN) scenario, or the access network device may be a relay station, an access point, a vehicle-mounted device, a terminal device, a wearable device, and an access device in a future 5G network or a network device in a future evolved PLMN network, and the like. Alternatively, the access network device may also be a router, a gateway, a switch, etc.
With the continuous development of electronic technology and internet technology, video data uploaded to the internet 3 by different content providers is more and more, and video data that the user 1 can select to watch is more and more abundant. However, in consideration of intellectual property protection of video data and a large amount of cost invested by content providers to produce video data, some content providers perform encryption protection on video data uploaded to the internet 3, and after a user 1 needs to pay for the encrypted video data, the terminal device 2 used by the user has the related authority to decrypt and play the video data, and then the video data uploaded by the content providers in the internet 3 can be played through the terminal device 2.
Therefore, a content provider needs to control encrypted video data uploaded to the internet so that a terminal device having an authority, which is used by a user who purchased the video data, can decrypt and play the encrypted video data; and a terminal device used by a user who has not purchased video data and has no authority cannot decrypt and play encrypted video data. In some technologies, an authentication server 31 and a content server 32 are provided in the internet 3, and the content server 32 can be used for storing and managing encrypted video data, and the authentication server 31 manages whether the terminal device has authority to decrypt and play the encrypted data, thereby realizing control processing of the encrypted video data.
For example, fig. 2 is a flow chart illustrating a processing method for encrypted video data in the prior art, and the method shown in fig. 2 can be executed by the terminal device 2, the authentication server 31 and the content server 32 in the system shown in fig. 1. The method comprises the following steps:
the content server performs an encryption process on the video data through step 1. In step 1, the producer 5 in the system shown in fig. 1 may produce the encrypted video data by using the terminal device 4 and upload the encrypted video data to the content server 32. Subsequently, the content server transmits information (e.g., a storage address) of the video data, encryption information (e.g., a key, a certificate (license), etc., used for encrypting the video data) to the authentication server through step 2, and the authentication server stores the received information.
The terminal device may request the authentication server to play the video data stored in the content server through step 3. Step 3 may also be referred to as play authentication, and may be used in the system shown in fig. 1, when the user 1 uses the terminal device 2 to play the video data stored in the content server 32, the terminal device 2 first needs to send an authentication request to the authentication server to request to play the video data stored in the content server 32.
The authentication server determines whether the terminal device has the right to play the video data through step 4. For example, in the system shown in fig. 1, if the user 1 does not purchase video data, the user 1 logs in a system of the terminal device 2 using information (account, password, etc.) of the user 1 or logs in an application program in the terminal device 2, and after the user is bound to the terminal device 2, the terminal device 2 does not have the authority to play the video data; if other users have purchased the video data, after the information of the user is bound with the terminal device 2, the terminal device 2 has the right to play the video data. In step 4, assuming that the authentication server determines that the terminal device 2 does not have the authority to play the video data, but the video content supports trial play (the trial play refers to that the terminal device can only play part of the video data, for example, the video data of the previous N minutes, where N is greater than 0), the authentication server returns address information of the video data to the terminal device through step 5, where the address information may be an IP address of a storage location of the video data in the content server.
Subsequently, the terminal device requests the content server to acquire video data, which may be a media stream requesting to acquire video data, through step 6 according to the address information of the video data fed back by the authentication server, and receives the video data sent by the content server through step 7. However, after the terminal device acquires the video data sent by the content server, if the terminal device determines that the video data is encrypted in step 8, decryption information (e.g., a key, a certificate (license), etc.) for decrypting the video data needs to be requested from the authentication server in step 9. The authentication server determines that although the terminal device has no authority to play the video data in step 10, the terminal device needs to perform trial play on the video data, and therefore, the authentication server sends decryption information of the video data to the terminal device in step 11.
Since the terminal device does not have the authority to play the video data, even if the decryption information of the video data and the address information of the video data are acquired, the terminal device performs play control on the played video data in step 12, performs trial play only for the first N minutes of the video data, and stops playing the video data after the trial play for the N minutes is completed, and prompts the user to purchase other video data.
Illustratively, fig. 3 is a schematic diagram of a display for viewing a play trial in the prior art, and fig. 4 is a schematic diagram of a display for prompting a purchase in the prior art; wherein, as shown in fig. 3, when the terminal device performs the trial play, the terminal device controls to play only the video data of the first 6 minutes in the video data, so that only the range of 6 minutes on the progress bar below the display interface allows the user to perform the dragging. And after 6 minutes of the trial play is finished, the terminal device prompts the user that the trial play has been completed and prompts the user to select whether to purchase the video data through the display interface as shown in fig. 4.
Subsequently, the user may purchase the video data through the terminal device, and the process of purchasing the video data is not limited in the present application. Then, after the terminal device determines that the user has purchased the video content, the authentication server may request to acquire the right to play the video data through step 13, and then the authentication server performs secondary authentication on the terminal device, and after determining that the user has purchased the video content, the right to play the video data may be allocated to the terminal device used by the user.
Finally, after having the right to play the video data, the terminal device continues to acquire the video data from the content server according to the address information of the video data acquired in step 5, for example, continues to acquire the media stream of the video data after the first N minutes, and decrypts and plays the acquired video data using the decryption information of the video data acquired in step 11.
In summary, as can be seen from the flowchart shown in fig. 2, in the video data processing technology in the prior art, if a terminal device requests an authentication server to play encrypted video data, the authentication server sends address information of the encrypted video data and decryption information of the encrypted video data to the terminal device, and the terminal device requests a content server to acquire the entire encrypted video data, and then controls playing of the encrypted video data. When the terminal equipment has the authority of playing the encrypted video data, the terminal equipment directly obtains the video data through the address information and can play the video data after decrypting the video data through the decryption information; when the terminal device does not have the right to play the encrypted video data, the terminal device needs to control that after the video data is acquired through the address information, the decryption is performed, the video data is tried to be played, and after the trying to be played is finished, the user is guided to purchase the video data to obtain the right to play the encrypted video data.
However, in the above process, even if the terminal device does not have the authority to play the encrypted video data, the terminal device receives the decryption information of the encrypted video data sent by the authentication server and stores the decryption information after requesting the authentication server to play the encrypted video data. At this time, there is a risk that the decryption information received and stored by the terminal device is maliciously attacked, unintentionally leaked, or stolen, and once the decryption information stored in the terminal device is acquired by some means, the terminal device without the authority to play the encrypted video can also decrypt and play the encrypted video data according to the decryption information. Therefore, the existing video data processing method is not beneficial to ensuring the safety of the encrypted video data, thereby reducing the safety performance of the encrypted video data.
The application provides a video data processing method and device, which are used for ensuring the safety of encrypted video data so as to increase the safety performance of the encrypted video data. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Fig. 5 is a schematic flowchart of a first embodiment of a video data processing method provided in the present application, where the embodiment shown in fig. 5 is executed by a terminal device, a first server, and a second server. The terminal device may have functions of controlling playing of video data, decrypting/decoding encrypted video data, and purchasing video data in cooperation with a user, and in this embodiment, the terminal device may be the terminal device 2 shown in fig. 1. The terminal equipment can perform playing control according to the return of the playing authentication device. If the scene is a trial-viewing scene, the client needs to limit the playable range according to the trial-viewing duration, and order is prompted when the playable range exceeds the range; the trial-and-watch period also supports the initiation of the order, and the playing can be continued from the breakpoint after the order. The first server may have functions of video data playing authentication, video data management, and management of video data purchased by a user, and the first server in this embodiment may be the authentication server 31 shown in fig. 1. The first server may also be referred to as a play authentication device, which is responsible for processing subscription and play authentication, returns relevant information of the client, such as a play address, a duration, a decryption certificate application parameter, and the like, according to a play authentication result, and may be used for playing video data. The second server may have functions of making video data, encrypting video data, and intercepting video data, and the second server in this embodiment may be the content server 32 shown in fig. 1. The second server can also be called a content production device, mainly completes production of video data, carries out content transcoding production according to whether the configuration supports trial viewing and trial viewing duration, and establishes the incidence relation between trial viewing content and the whole piece in metadata management; and finally, the video data is issued to the play authentication device.
Specifically, the video data processing method provided by this embodiment includes:
s101: the second server acquires the first video data.
Specifically, the second server in this embodiment is configured to store and manage the first video data, and then the second server first acquires the first video data in S101. The first video data may be unencrypted video data, e.g. the first video data may be a complete movie. The format of the first video data is not limited in the present application, and may be, for example, formats such as hls (http silver), dash (dynamic adaptive streaming over http), MP4(moving picture experts group 4), and the like.
Optionally, in S101, the second server may obtain the first video data uploaded to the second server by the producer of the video data through the device used by the producer, or the second server may further obtain the first video data from the internet according to an instruction of the producer. Alternatively, the second server may also obtain the first video data from a removable storage device such as a removable hard disk, a usb disk, a CD, or the like.
S102: the second server determines second video data from the first video data.
And after the second server acquires the first video data, determining second video data according to the first video data. The second video data described in this embodiment is used for the terminal device to perform the trial viewing and playing of the first video data. The trial playing means that for a terminal device which does not have the authority to play the first video data, the second video data is played first to attract a user of the terminal device to purchase the video data, so that the terminal device can acquire and play the first video data only after acquiring the authority to play the first video data.
Optionally, in this embodiment, the second video data is a part of the first video data. That is, the second video data determined in this embodiment is from the first video data, and when the length of the first video data is M minutes, the second video data includes N minutes of video data in the first video data, where 0 < N < M.
In one specific implementation, in S102, the second server may intercept the first N minutes of the first video data, so as to obtain second video data including the first N minutes of the first video data. Since the first video data is usually related to the slice and the key frame therein, if the second video data of the previous N minutes is mechanically intercepted, the deletion of the key frame in the second video data may be caused to affect the playing effect, and therefore, in order to ensure the playing effect of the terminal device, when the second server intercepts the first video data to obtain the second video data, the intercepted duration may also be slightly longer than the actually allowed N minutes. For example, for the first video data with the duration of 120 minutes, the second video data is obtained by intercepting the first 6 minutes.
In another specific implementation manner, in S102, the second server may further perform interception according to a specific location in the first video data, so as to obtain second video data including N minutes of a-b time in the first video data, where the a-b time may be a preset portion in the first video data or a portion designated by a producer. For example, the second server may intercept a portion of the first video data with more splendid content according to an instruction of a producer to obtain the second video data, so that the terminal device can attract a user of the terminal device when the terminal device performs a trial play on the second video data.
In another specific implementation manner, in S102, the second server may further sample the first video data sequentially at intervals of a preset number of frames, and the total sampling may intercept the second video data composed of frames with larger intervals for N minutes. The second video data obtained at this time is not continuous video data when played, but in the form of an interval sample, a preview of the first video data is realized by playing the second video data, so that the user can roughly determine what may be included in the entire first video data.
Optionally, in S102, the second server further performs encryption processing on the first video data without performing encryption processing on the determined second video data. The method for encrypting the first video data by the second device is not limited in the present application. For example, it may be a proprietary encryption method, or it may be a different Digital Rights Management (DRM) solution. The second device may determine the encrypted first video data and the unencrypted second video data after S102. Furthermore, the second video data that is not subject to encryption processing may also be referred to as a video "clear stream".
S103: the second server establishes an incidence relation between the first video data and the second video data.
Specifically, in S103, the second server establishes an association relationship between the first video data and the second video data determined in S102. In a specific implementation, the association relationship may be an association relationship between identification information of the first video data and identification information of the second video data, and the identification information may be, for example: name, duration, source, storage address, etc. of the video data. The association relationship may also be stored in the form of a table, a mapping table, or the like. Determining second video data according to the first video data through the mapping relation; alternatively, the first video data may be determined from the second video data by the mapping relationship.
S104: and the second server sends the information of the first video data, the information of the second video data, the encryption information of the first video data and the association relation to the first server, and the first server stores the information of the first video data, the information of the second video data, the encryption information of the first video data and the association relation.
Wherein the information of the first video data includes: address information, such as an IP address, of the first video data stored in the second server. The information of the second video data includes: address information, such as an IP address, of the second video data stored in the second server. The encryption information of the first video data includes: the first video data is encrypted by the key, and the second server sends the key of the first video data to the first server.
The second server sends the information of the first video data, the information of the second video data, the encryption information of the first video data and the association relationship determined in S103 to the first server in S104, and correspondingly, the first server receives the information sent by the second server and then stores the information.
In summary, through S101 to S104, the second server implements encryption processing on the first video data, obtains the second video data for trial playing according to the first video data, and sends the association information of the first video data and the second video data to the first server. After the subsequent terminal device requests the first server to play the first video data, the first server can feed back the first video data or the second video data to the terminal device according to whether the terminal device has the authority of playing the first video data. The process is described in detail below.
S105: the terminal equipment sends a playing request of the first video to the first server. The first server receives a playing request of first video data sent by the terminal equipment.
Specifically, after the second server acquires the first video data, and the first server acquires the information of the first video data, the information of the second video data, the encryption information, and the association relationship, the first server may perform play control on the first video data stored in the second server.
When the terminal device needs to play the first video data stored in the second server, the terminal device first sends a play request of the first video data to the first server through S105. And for the first server, receiving a playing request of the first video data sent by the terminal equipment.
Optionally, in this embodiment, the terminal device may send a play request of the first video data to the first server after determining that the user needs to play the first video data according to an instruction of the user using the terminal device. The playing request may carry identification information of the first video data, so that the first server determines, through the identification information, the first video data requested to be played by the terminal device. For example, if the identification information included in the play request sent by the terminal device to the first server is the name of movie a, the first server may determine that the first video data requested to be played by the terminal device is movie a according to the identification information.
S106: when the terminal equipment does not have the right of playing the first video data, the first server determines the address information of the second video data.
Subsequently, in S106, the first server determines whether the terminal device that transmitted the play request has the right to play the first video data. When the first server determines that the terminal equipment does not have the right of playing the first video data, the first video data is not sent to the terminal equipment immediately, and the address information of the second video data related to the first video data is determined according to the first video data and the stored association relation.
More specifically, if the association relationship is an association relationship between the identification information of the first video data and the identification information of the second video data, the first server may determine the identification information of the second video data according to the identification information of the first video data and the association relationship acquired in S105. And then, determining the address information of the second video data further according to the identification information of the second video data. Or, the association relationship may also be address information of the first video data and address information of the second video data, and after the first server determines the address information of the first video data requested by the terminal device, the first server further determines the address information of the second video data according to the association relationship.
Optionally, the authority in this embodiment is related to a user using the terminal device. The first server may determine whether the terminal device has the right to play the first video data through the identification information provided by the terminal device, or the first server may also determine whether the terminal device has the right to play the first video data through information corresponding to the terminal device stored in the first server.
For example, if the user a does not purchase the first video data, after the user a logs in the terminal device using the information (account, password, etc.) of the user a, the first server receives a playing request of the first video data sent by the terminal device, and may determine that the identification information corresponding to the user a stored in the first server is that the first video data is not purchased, and then the first server may determine that the terminal device does not have the authority to play the first video data. For another example, after the user B has purchased the first video data, and the user B logs in the terminal device using the information of the user B, the first server receives the play request of the first video data sent by the terminal device, and may determine that the identification information corresponding to the user B stored in the first server is the purchased first video data, and then the first server may determine that the terminal device has the right to play the first video data.
Optionally, a user of the terminal device may purchase the first video data through the second server, and after the user purchases the first video data, the second server may update the identification information of the user to the first server, so that after the first server receives a play request of the first video data, it can determine whether the terminal device has an authority to play the first video data according to the identification information of the user corresponding to the terminal device.
It should be noted that, in the present application, whether the first server has the right to play the first video data is processed for the first server, but a manner for the user to purchase the first video data is not limited, the user may purchase the first video data from a provider of the first video data through any transaction and payment manner, and after the user purchases the first video data, the terminal device used by the user has the right to play the first video data, and the right may be identified by the terminal device or identified by the first server; when the user does not purchase the first video data, the terminal device used by the user does not have the authority to play the first video data.
Optionally, in S106, if the first server determines that the terminal device has the right to play the first video data, after directly determining the first video data, the address information of the first video data may be sent to the terminal device.
S107: the first server sends the address information of the second video data to the terminal device.
Subsequently, the first server sends the address information of the second video data determined in S106 to the terminal device, and correspondingly, the terminal device receives the address information of the second video data sent by the first server. The address information may be a stored IP address of the second video data in the second server.
S108: and the terminal equipment sends a playing request of the second video data to the second server according to the address information. Correspondingly, the second server receives a playing request of the second video data sent by the terminal equipment.
The terminal device transmits a play request of the second video data to the second server according to the address information of the second video data received in S107.
S109: and the second server sends the second video data to the terminal equipment according to the playing request of the second video data. Correspondingly, the terminal equipment receives the second video data sent by the second server.
And the second server sends the second video data to the terminal equipment according to the playing request of the second video data.
S110: and the terminal equipment plays the second video data and can pop up prompt information, wherein the prompt information is used for prompting a user to purchase the first video data.
Specifically, after the terminal device acquires the second video data, since the second video data is not encrypted, the terminal device can directly play the second video data. And after the second video data is finished, prompting the user to purchase the first video data in a mode of popping up prompt information.
In summary, through S105 to S110, after the terminal device sends the play request of the first video data to the first server, the first server determines whether the terminal device has the right to play the first video data. If the terminal device does not have the authority of playing the first video data, the first server does not send the information of the first video data to the terminal device, but sends the information of the associated unencrypted second video data to the terminal device, so that the terminal device can directly receive and play the second video data. The second video data is part of the video data in the first video data and is used for realizing the trial viewing and playing of the first video data.
Therefore, in the above process, for a terminal device that does not have the authority to play the first video data, the address information and the decryption information of the first video data are not received, and the first video data is only viewed through the second video data. Therefore, the terminal equipment which does not have the authority of playing the first video data can not obtain and store the address information and the decryption information of the first video data, and the terminal equipment which does not have the authority of playing the first video data can be ensured not to directly and maliciously obtain the relevant information of the first video data stored in the terminal equipment by some means and then play the first video data. In the prior art, the risks that the address information and the decryption information of the encrypted first video data are maliciously attacked, unintentionally leaked or stolen and the like are reduced, so that the safety of the encrypted first video data is ensured, and the safety performance of the first video data is improved.
Optionally, in a specific implementation manner of the step S110, after the terminal device completes playing the second video data, or when the terminal device plays the second video data, the terminal device may prompt the user to purchase the first video data by popping up a prompt message; or, the terminal device may pop up a prompt message to prompt the user to purchase the first video data after detecting the preset action of the user. Fig. 6 is a schematic display diagram of a terminal device playing second video data according to the present application, and fig. 7 is a schematic display diagram of a terminal device prompting to purchase first video data according to the present application.
Specifically, in the example shown in fig. 6, when the terminal device plays the second video data, even if the duration of the second video data is less than the duration of the first video data, the terminal device in the present application may display the entire duration of the first video data on the progress bar below the display interface. For example, the duration of the first video data is 120 minutes, and the duration of the second video data is 6 minutes, when the terminal device plays the second video data, the lower progress bar is also displayed as the duration of the first video data being 120 minutes. At this time, the user may drag the progress bar, and after the terminal device detects that the user drags the progress bar to a preset action after 6 minutes, the terminal device may prompt the user to select whether to purchase the first video data through the display interface shown in fig. 7.
Therefore, in the specific implementation manner, since the terminal device without the play permission only plays the second video data but does not actually acquire the first video data, from the perspective of user perception experience, the duration of the first video data can be displayed to the user, so that the user can select the play progress through the progress bar, and further, the perception experience of the user is improved.
After the user determines to purchase the first video data through the display interface as shown in fig. 7, the user may continue to complete the purchase of the first video data through the terminal device. For example, after the user sends a purchase request to the first server or the second server (or another server for payment management set by the provider of the first video data) through the terminal device, performs mobile payment, and the like, the purchase of the first video data is completed. The terminal device used by the user has the right to play the first video data after purchase.
Alternatively, in the example shown in fig. 5, the terminal device used by the user may request the first server to acquire the right to play the first video data through S111 to implement the purchase of the first video data, then the first server allocates the right to play the first video data to the terminal device used by the user who purchased the first video data through S112, and then the corresponding terminal device acquires the right to play the first video data allocated to the terminal device by the first server through S112, so that the terminal device has the right to play the first video data. Alternatively, the distribution right may be that the first server modifies the identification information of the terminal device stored by the first server.
Subsequently, after having the right to play the first video data, the terminal device may send a play request of the first video to the first server again, and cause the first server to return the address information of the first video data to the terminal device, and implement playing. Specifically, as shown in fig. 5, the video data processing method provided in this embodiment further includes:
s113: the terminal equipment sends a playing request of the first video data to the first server. Correspondingly, the first server receives a playing request of the first video data sent by the terminal equipment.
S114: the first server judges whether the terminal equipment has the authority of playing the video data again, and at the moment, the first server determines the first video data because the terminal equipment already has the authority of playing the first video data.
S115: the first server determines that the terminal device can play the first video data through S114, and sends the address information of the first video data, which may be the stored IP address of the first video data in the second server, to the terminal device through S115.
S116: the terminal device sends a play request of the first video data to the second server according to the address information received in S115. Correspondingly, the second server receives a playing request of the first video data sent by the terminal equipment.
S117: and the second server sends the first video data to the terminal equipment according to the playing request of the first video data. Correspondingly, the terminal equipment receives the first video data sent by the second server.
S118: since the first video data is encrypted in this embodiment, the terminal device determines in S118 that the first video data is encrypted, and passes the result
S119: and sending a decryption request of the first video data to the first server, wherein the decryption request is used for requesting decryption information of the first video data from the first server. Correspondingly, the first server receives a decryption request of the first video data sent by the terminal equipment.
S120, after receiving the decryption request of the first video data through S119, the first server may determine whether the terminal device has the right to play the first video data again, and if so, after determining the decryption information of the first video data, the first server passes
S121: the first server sends decryption information of the first video data to the terminal device. Correspondingly, the terminal equipment receives the decryption information sent by the first server. The decryption information may be a key for encrypting the first video data or a certificate (license) for decrypting the first video data, and the key and the certificate may be used for decrypting the first video data.
S122: the terminal device decrypts the first video data acquired in S117 according to the decryption information acquired in S121, and finally realizes playing of the first video data.
It is understood that the above processes S113-S122 may also be executed by the terminal device, the first server and the second server as a separate embodiment, and then the terminal device has the right to play the first video data.
To sum up, through the processes of S111 to S122, after acquiring the playback permission of the first video data, the terminal device may request to play the first video data from the first server again, and request decryption information of the first video data; at this time, after determining that the terminal device has the right to play the first video data, the first server may send the address information of the first video data to the terminal device, and may send the decryption information of the first video data to the terminal device. Therefore, the terminal equipment which really has the authority of playing the first video data can acquire and use the address information and the decryption information of the first video data, the safety performance of the address information and the decryption information of the encrypted first video data is further improved, the encrypted first video data is not easy to acquire by the terminal equipment without the authority and has the risk of embezzlement, and the safety performance of the encrypted first video data is further ensured.
Fig. 8 is a schematic flowchart of a second embodiment of a video data processing method provided in the present application, where the embodiment shown in fig. 8 is executed by a terminal device, a first server, and a second server. The terminal device may have functions of controlling playing of video data, decrypting/decoding encrypted video data, and purchasing video data in cooperation with a user, and in this embodiment, the terminal device may be the terminal device 2 shown in fig. 1. The first server may have functions of video data playing authentication, video data management, and management of video data purchased by a user, and the first server in this embodiment may be the authentication server 31 shown in fig. 1. The second server may have functions of making video data, encrypting video data, and intercepting video data, and the second server in this embodiment may be the content server 32 shown in fig. 1. Specifically, the video data processing method provided by this embodiment includes:
s201: the second server acquires the first video data.
Specifically, S201 may refer to S101 shown in fig. 5, and the implementation manner and principle thereof are the same and are not described again.
S202: the second server encrypts part of the video data in the first video data.
Specifically, the second server performs partial encryption processing on the first video data after acquiring the first video data. In this embodiment, the encryption method of part of the video data in the first video data is not limited. In this embodiment, since part of the video data in the first video data is encrypted and part of the video data is not encrypted, the part of the first video data that is not encrypted can be used for the terminal device to perform the preview playing of the first video data when the terminal device does not have the decryption information of the first video data. The trial playing means that for a terminal device which does not have the authority to play the first video data, an unencrypted part of the first video data is played first to attract a user of the terminal device to purchase the video data, so that the terminal device can acquire and play the first video data only after acquiring the authority to play the first video data.
In a specific implementation manner, when the duration of the first video data is N minutes, and the encrypted part of the video data in the first video data may be the last N-M minutes in the first video data, in S102, the second server may encrypt the video data of the first N minutes and the video data of the last N-M minutes in the first video data without encrypting the video data. For example, in S102, the first server does not encrypt the first video data of 120 minutes in the first 6 minutes and encrypts the video data of 114 minutes later.
In another specific implementation, the second server may encrypt video data at a particular a-b time in the first video data, while video data other than the particular location is not encrypted. The a-b moments may be preset portions of the first video data or portions specified by the producer.
S203, the second server sends the obtained information of the first video data and the encryption information of the part of the video data of the first video data to the first server, and correspondingly, the first server receives and stores the information sent by the second server.
Wherein the information of the first video data includes: address information, such as an IP address, of the first time-frequency data stored in the second server. The encryption information of the first video data includes: an encryption mode for encrypting a portion of the video data in the first video data and/or decryption information for decrypting the first video data. For example, the second server encrypts part of the data in the first video data using the key, and the second server transmits the key to the first server.
In summary, through the above S201 to S204, the second server implements partial encryption processing on the first video data, and the obtained first video data can be used for trial play and sends information of the first video data to the first server. After the subsequent terminal equipment requests the first server to play the first video data, the first server can send the address information of the first video data to the terminal equipment, and send decryption information of the encrypted part of the video data in the first video data to the terminal equipment according to whether the terminal equipment has the authority of playing the first video data. The process is described in detail below.
S204: the terminal device sends a play request of the first video data to the first server,
specifically, after the second server acquires the first video data and the encryption information of the first video data, the first server may perform play control on the first video data stored in the second server.
When the terminal device needs to play the first video data stored in the second server, the terminal device first sends a play request of the first video data to the first server through S204. And for the first server, receiving a playing request of the first video data sent by the terminal equipment.
Optionally, in this embodiment, the terminal device may send a play request of the first video data to the first server after determining that the user needs to play the first video data according to an instruction of the user using the terminal device. The playing request may carry identification information of the first video data, so that the first server determines, through the identification information, the first video data requested to be played by the terminal device. For example, if the identification information included in the play request sent by the terminal device to the first server is the name of movie a, the first server may determine that the first video data requested to be played by the terminal device is movie a according to the identification information.
S205: when the terminal equipment does not have the authority of playing the first video data, the address information of the first video data is determined.
Subsequently, in S106, the first server determines whether the terminal device that transmitted the play request has the right to play the first video data. When the first server determines that the terminal device does not have the right of playing the first video data, only the address information of the first video data is sent to the terminal device, but decryption information of the first video data is not sent to the terminal device, so that the terminal device cannot decrypt the encrypted part of the first video data. The manner of determining whether the terminal device has the authority to play the first video data by the first server may refer to the record in S106, and is not described again.
Optionally, in S205, if the first server determines that the terminal device has the right to play the first video data, it is determined that the address information of the first video data and the decryption information of the first video data are sent to the terminal device.
S206, the first server sends the address information of the first video data to the terminal equipment.
Subsequently, the first server transmits the address information of the first video data determined in S205 to the terminal device, and correspondingly, the terminal device receives the address information of the first video data transmitted by the first server. The address information may be a stored IP address of the first video data in the second server.
And S207, the terminal equipment sends a playing request of the first video data to the second server according to the address information. Correspondingly, the second server receives a playing request of the first video data sent by the terminal equipment.
S208, the second server sends the first video data to the terminal equipment according to the playing request of the first video data. Correspondingly, the terminal equipment receives the first video data sent by the second server.
S209, the terminal device plays the unencrypted part of the first video data and can pop up prompt information, wherein the prompt information is used for prompting to purchase the partially encrypted first video data.
Specifically, after the terminal device acquires the first video data through S208, since part of the data in the first video data is encrypted, another part of the data is not encrypted, and the terminal device does not have decryption information of the encrypted part of the first video data, in S209, the terminal device can only play the unencrypted part of the first video data, thereby implementing a preview play of the first video data by the terminal device.
In summary, through S204 to S209, after the terminal device sends the play request of the first video data to the first server, the first server determines whether the terminal device has the right of part of the first video data. If the terminal device does not have the authority of playing the first video data, the first server sends the address information of the first video data to the terminal device, and does not send decryption information of the encrypted part in the first video data to the terminal device, so that the terminal device can only realize the trial playing of the first video data by playing the unencrypted part in the first video data.
Therefore, in the above process, for a terminal device that does not have the authority to play the first video data, although the address information of the first video data can be received, the decryption information of the encrypted portion in the first video data is not received, so that the terminal device cannot decrypt and play the entire first video data despite having the video data, and only can realize the trial play through the unencrypted portion in the first video data. Therefore, the terminal equipment which does not have the authority of playing the first video data can not obtain the decryption information which can not store the first video data, and the terminal equipment which does not have the authority of playing the first video data can not directly and maliciously acquire the relevant information of the first video data stored in the terminal equipment by some means and then play the information. In the prior art, the risks that the address information and the decryption information of the encrypted first video data are maliciously attacked, unintentionally leaked or stolen and the like are reduced, so that the safety of the encrypted first video data is ensured, and the safety performance of the first video data is improved.
Optionally, in a specific implementation manner of the step S209, after the terminal device finishes playing the unencrypted portion of the first video data, or when the terminal device plays the unencrypted portion of the first video data, the terminal device may prompt the user to purchase the first video data by popping up a prompt message; or, the terminal device may pop up a prompt message to prompt the user to purchase the first video data after detecting the preset action of the user. The content displayed on the display interface of the terminal device may refer to the embodiments shown in fig. 6 and fig. 7, and the implementation manner and principle thereof are the same, and are not described again.
Subsequently, after the user determines to purchase the first video data, the user may proceed to complete the purchase of the first video data through the terminal device. For example, after the user sends a purchase request to the first server or the second server (or another server for payment management set by the provider of the first video data) through the terminal device, performs mobile payment, and the like, the purchase of the first video data is completed. The terminal device used by the user has the right to play the first video data after purchase.
Alternatively, in the example shown in fig. 8, a terminal device used by a user may request the first server to acquire the right to play the first video data through S210 to implement purchase of the first video data, the first server allocates the right to play the first video data to the terminal device used by the user who purchased the first video data through S211, and the corresponding terminal device acquires the right to play the first video data allocated to the terminal device by the first server through S211, so that the terminal device has the right to play the first video data. Alternatively, the distribution right may be that the first server modifies the identification information of the terminal device stored by the first server.
Subsequently, after having the right to play the first video data, the terminal device may send a play request of the first video to the first server again, and make the first server return decryption information of the encrypted portion in the first video data to the terminal device, so that the terminal device can realize the play of all the first video data after decrypting the encrypted portion in the first video data. Specifically, as shown in fig. 8, the video data processing method provided in this embodiment further includes:
s212: the terminal device sends a playing request of the first video data to the first server, and correspondingly, the first server receives the playing request of the first video data sent by the terminal device.
S213: the first server judges whether the terminal equipment has the authority of playing the video data again, and at the moment, the first server determines the decryption information of the first video data because the terminal equipment already has the authority of playing the first video data.
S214: the first server sends decryption information of the first video data to the terminal device. Correspondingly, the terminal equipment receives the decryption information sent by the first server. The decryption information may be a key used for encrypting the partial data in the first video data, or a certificate (license) for decrypting the encrypted partial data in the first video data, and the key and the certificate may be used for decrypting the first video data.
S215: the terminal device decrypts the encrypted portion of the video data in the acquired first video data according to the decryption information of the first video data acquired in S215 to obtain the first video data, and finally plays the first video data.
To sum up, through the above-mentioned processes of S210-S215, the terminal device may request to play the first video data from the first server again after acquiring the play right of the first video data, and request the decryption information of the encrypted portion in the first video data; at this time, the first server may send decryption information of the encrypted portion of the first video data to the terminal device after determining that the terminal device has the right to play the first video data. Therefore, the terminal equipment which really has the authority of playing the first video data can acquire the decryption information of the first video data and decrypt the encrypted part in the first video data for playing, so that the safety performance of the address information and the decryption information of the encrypted first video data is improved, the encrypted first video data is not easy to acquire by the terminal equipment without the authority and has the risk of embezzlement, and the safety performance of the encrypted first video data is further ensured.
In addition, the way of partially encrypting the first video data in the first embodiment and the second embodiment of the present application may also be applied to a video sharing scene, and support an HTML5 page. When the first device shares the first video data with the second device by sending an HTML5 page, at this time, after the HTML5 page received by the second device requests the first server to play the first video data, the first server only returns address information of the second video data to the HTML5 page, so that the HTML5 page of the second device can request and play the second video data from the second server, and the second device without the right of playing the first video data can perform trial playing on the first video data through the second video data; subsequently, after the user of the second device subscribes to the first video data, the HTML5 page of the second device requests the first server to play the first video data, and the first server returns the address information of the first video data to the HTML5 page, so that the HTML5 page of the second device requests the second server to play the first video data. For a specific implementation, reference may be made to the embodiment shown in fig. 5, and the second device may be a terminal device shown in fig. 5, which is not described again. Or after the HTML5 page received by the second device requests the first server to play the first video data, the first server returns the address information of the partially encrypted first video data to the HTML5 page, so that the HTML5 page received by the second device can also perform trial play on the first video data by playing the video data which is not encrypted in the first video data. Subsequently, after the user of the second device subscribes to the first video data, the HTML5 page of the second device requests the first server to play the first video data, and the first server returns the decryption information of the first video data to the HTML5 page, so that the HTML5 page of the second device decrypts and plays the first video data. For a specific implementation, reference may be made to the embodiment shown in fig. 8, and the second device may be a terminal device shown in fig. 8, which is not described again. Therefore, when the video data processing method of the embodiment of the application is used in a video sharing scene, the compatibility of sharing the HTML5 can be realized, no limitation is imposed on a browser, no display is given to the type of a DRM solution, and the realization difficulty is low.
