Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The video playing method provided by the present disclosure may be applied to the application environment shown in fig. 1. The encryption client 102 interacts with a source station 104 in a Content Delivery Network (CDN) through a network, the source station 104 interacts with a CDN node 106 in the content delivery network through the network, each client 108 interacts with the CDN node 106 through the network, and a player is configured in each client 108 for video playing. Specifically, the encryption client 102 is configured to encrypt a video to be secured and upload the secured video and/or unsecured video to the source station 104. The source station 104 is configured to distribute the secure and/or unsecured video to the CDN nodes 106 such that the clients 108 can download the secure and/or unsecured video through the CDN nodes 106. When the video needs to be played, the player 110 reads the cached secure video and/or unsecure video from the client 108, and the client 108 sends the decryption key encrypted and stored in the picture file to the player 110. Next, the player 110 detects an encrypted identifier in the video to be played, and if it is detected that the encrypted identifier exists in the video, loads a decryption key matched with the encrypted identifier, and further decrypts the video according to the decryption key to obtain a decrypted video. If the video is not encrypted, the video can be directly played.
In another application environment, the encryption operation on the video to be encrypted can be implemented by using the server, and then, in combination with the last application scenario, as an adjustment, the encryption client 102 only needs to upload the video to be encrypted to the server, and then the subsequent encryption task is completed by the server. In yet another application environment, the encryption client 102 may be discarded, i.e. the encryption client 102 is not required to upload video, but the server directly reads its stored video data and encrypts the video to be kept secret. It can be understood that the video playing method provided by the present disclosure can be applied to various application scenarios, and the three application scenarios are also only exemplary, and the video playing method is not limited to the three application scenarios.
Fig. 2 is a flowchart illustrating a video playing method according to an exemplary embodiment, where the video playing method is used in a player, as shown in fig. 2, and includes the following steps.
In step S202, in response to a video playing instruction, the player detects an encryption identifier in a video to be played.
The player refers to software capable of playing video files stored in a digital signal form, and may also refer to an electronic device product having a function of playing the video files. Illustratively, the player may be an application embedded in the client.
Alternatively, the player is embedded in the client for example. First, before step S202, the client needs to download and cache a corresponding video from the server. When a video playing requirement is detected, the client sends the video to the player in response to the video playing instruction. The player will detect the encrypted identification in the video to be played. Wherein the encrypted identifier is used to distinguish between encrypted video and unencrypted video. Optionally, the format of the video is MP4 format.
In step S204, if the player detects that the video to be played has the encrypted identifier, the player loads a decryption key matching the encrypted identifier.
Specifically, if the player detects that the encrypted identifier exists in the video, the player first matches the corresponding decryption key, and loads the decryption key after the matching is successful. Alternatively, the decryption key may be sent by the client to the player so that the player can obtain the decryption key conveniently and quickly.
In step S206, the player decrypts the video to be played according to the decryption key, so as to obtain decrypted video data.
The decrypted video data may be understood as video data with the encryption identifier removed.
Specifically, after loading the decryption key, the player decrypts the encrypted video according to the decryption key, thereby obtaining decrypted video data. And then the player plays the video according to the decrypted video data.
In the video playing method, when a video playing requirement exists, the player firstly carries out encryption detection on the video to be played, and if the video is detected to be encrypted, the player acquires the decryption key to decrypt the video, so that the video can be played according to the decrypted video data. It can be understood that before the player plays the video, the video to be kept secret is still in an encrypted state, so that the video can be prevented from being stolen or leaked in advance, and the confidentiality and the safety of the video and related information before playing are improved.
In an exemplary embodiment, as shown in fig. 3, step S202 includes the steps of:
in step S2022, in response to the video playing instruction, the player acquires identification information of a video to be played.
In step S2024, the player detects the encrypted identification in the identification information.
The identification information is used for marking the attribute of the video resource. Optionally, the identification information may include a uniform resource identifier, uri. The encrypted identification may be integrated in the uniform resource identifier. The encrypted identification may be in a consistent identification format with the identification information, such as: the identification information adopts a character string format, so that the encrypted identification also adopts the character string format for the convenience of identification and analysis. Of course, the encrypted identifier may adopt an identifier format different from that of the positioning identifier, as long as the player can recognize the encrypted identifier and read the information therein, so as to complete the subsequent decryption process.
Specifically, when the player reads a video cached by the client, the player acquires identification information corresponding to the video, such as the video uri. Then, the player detects whether the identification information contains an encrypted identifier, and if the identification information contains the encrypted identifier, the player determines that the video is encrypted. And if the identification information is judged not to contain the encrypted identification, judging that the video is not encrypted. Optionally, as mentioned above, when the video uri is used for the encryption judgment, since the video uri is in the character string format, the encryption identifier is correspondingly in the character string format. It is understood that the character string corresponding to the encrypted identifier is substantially a substring in the character string corresponding to the video uri, so that once the player detects that the video uri includes the substring corresponding to the encrypted identifier, it can determine that the video uri is encrypted. The encryption mode realizes the encryption of the video by an external intervention means, and whether the video is encrypted can be judged by only detecting the external means when the video is encrypted and detected, so that the integrity of video information can be ensured.
For example, assume that an initial uri of a video is: http://192.168.1.100:8080/video/1. avi. To encrypt video, specific strings are used such as: sf540p as an encryption identifier, and added to the original uri, that results in encrypted video uri: http://192.168.1.100:8080/video/1.avi _ sf540p _. In this way, the player can determine that the video is encrypted as long as it detects that the video uri includes the specific character string of _ sf540 p-. On the contrary, if the specific character string of _ sf540 _ 540p _ is not detected in the video uri, it is determined that the video is not encrypted, and the player can play the video without decrypting the key.
In an exemplary embodiment, the method further comprises the steps of:
s203, in response to the video playing instruction, the player receives the decryption key sent by the client.
The decryption key is obtained by analyzing the image file stored by the client through the client, and the image file is the image file comprising the decryption key.
Specifically, before step S203, the client stores the decryption key in the picture file included therein. Further, in order to improve storage security, the client encrypts the picture file so that the decryption key is also in an encrypted state. Based on this, when the player determines that the video is encrypted, the required decryption key needs to be obtained from the encrypted picture file after the encrypted picture file is decrypted. Alternatively, the client may send the decryption key along with the video when sending it to the player. In addition, the client may also send the decryption key to the player after the player determines that the video is encrypted.
Optionally, the picture file may be a png file, a jpg file, a bmp file, or the like, and of course, may also be a picture file in other formats, which is not limited in this embodiment.
For example, taking the png file as an example, the png file is stored in the client, and the png file can be stored in an encrypted manner as a decryption key, for example, a carrier of the decryption key. Optionally, the picture encryption method may select a modified picture suffix name method, a compressed encryption method, and the like. As an example, the png file is securely encrypted by adopting a compression encryption mode. Furthermore, the png file can be packaged into an installation package corresponding to the client, so that the security of video storage can be improved by increasing the difficulty in acquiring the decryption key, and the video content is prevented from being leaked in advance.
In an exemplary embodiment, as shown in fig. 4, step S206 includes the steps of:
in step S2062, the player determines a video segment to be played in the video.
In step S2064, the player decrypts the video segment to be played according to the decryption key, so as to obtain a decrypted video segment.
In step S2066, the player plays the decrypted video segment and performs decryption on the video segment to be played next in parallel.
Specifically, before step S206, a plurality of video segments obtained by the video according to the preset division mode need to be encrypted by the encryption device, respectively, so as to obtain encrypted video segments, for example, 16 bytes are used as an encryption unit for encryption. Therefore, when the video is played, the player can also play according to the video clips, so that the video of any clip can be extracted to play, and the flexibility of video playing is improved. Before the player plays the video clip, the video clip to be played needs to be decrypted according to the decryption key, so as to obtain the decrypted video clip. For example, a decryption unit of 16 bytes, for example, of the video segment to be played is decrypted by the decryption key. Therefore, the effect of playing while decrypting can be realized, and the playing efficiency is higher.
Based on the same inventive concept, a video playing method is also provided, which is exemplified by the application of the method to the client 108. The method comprises the following steps:
in step S212, the client caches the video sent by the server.
Wherein the video comprises encrypted video and/or non-encrypted video. Specifically, the client receives the video sent by the server and caches the video in the client.
In step S214, in response to the video playing instruction, the client sends the cached video and the decryption key to the player, so that when the player detects that the encrypted identifier exists in the video, the player decrypts the video according to the decryption key to obtain decrypted video data.
When the playing requirement exists, the client responds to the video playing instruction and sends the cached video and the decryption key to the player. And when detecting that the encrypted identifier exists in the video, the player decrypts the video according to the decryption key to obtain decrypted video data, and then plays the video according to the decrypted video data.
In the video playing method, the encrypted video is cached in the client, so that the video to be kept secret cached by the client is still in an encrypted state before the player plays the video, and the confidentiality and the safety of the video and the related information before playing are improved.
In an exemplary embodiment, the video playing method further includes the steps of:
in step S222, the client reads the stored picture file containing the decryption key;
in step S224, the client parses the picture file to obtain a decryption key.
Specifically, before step S222, the client stores the decryption key in the picture file included therein in advance. Further, in order to improve storage security, the client encrypts the picture file so that the decryption key is also in an encrypted state. Furthermore, when the decryption key is needed, the client side decrypts the image file and then analyzes the image file to obtain the decryption key.
In this embodiment, by increasing the difficulty in obtaining the decryption key, the security of video storage can be improved, and video content is prevented from leaking in advance.
Further, in one embodiment, the picture file may be packaged in the client's installation package in advance, so that the picture file is downloaded along with other download resources when the client is downloaded. When the client side obtains the picture file, the compression packet needs to be decompressed first to obtain the picture file. It can be understood that, by adding the operation step of obtaining the picture file, the difficulty of obtaining the decryption key can be further increased.
It should be understood that although the various steps in the flow diagrams of fig. 2-4 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not limited to being performed in the exact order illustrated and, unless explicitly stated herein, may be performed in other orders. Moreover, at least some of the steps in fig. 2-4 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed in sequence, but may be performed in turn or alternately with other steps or at least some of the other steps.
