Detailed Description
The embodiment of the invention provides an information processing method and related equipment, which are used for reducing the loss of a video website by identifying the false playing of a video.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a flowchart of a possible information processing method provided in an embodiment of the present application specifically includes:
101. the server generates a first public and private key pair;
in order to improve the security of data transmission between the server and the client, the communication between the server and the client may be encrypted. In the embodiment of the invention, an asymmetric RSA encryption algorithm can be adopted to generate the public and private key pair, wherein when a client opens one video for playing each time, a pair of public and private key pairs can be regenerated, and the public and private key pairs of each video are ensured to be different.
Optionally, in the present invention, the server generates a first public and private key pair including a first public key and a first private key according to information of a current video being played by the client. The specific first private key can be generated by using a random number, the first public key calls an interface function of the RSA to generate a corresponding public key, the first private key and the first public key are in a unique pairing relationship, and the implementation mode for generating the first public and private key pair comprises the following steps:
step 1, generating random data;
Randdata＝rand()；
and generating a random data Randdata by calling a system function rand.
Step 2, generating an Md5 value of the current video as a first private key according to the Identification (ID) number and the random number of the current video;
ClientPrivatekey＝Md5.Create(Randdata+VideoId)；
where VideoId is used to indicate the ID number of the current video, it should be noted that the ID of the current video can be understood as the room number of each video.
The Md5 value of the random data and the ID number of the current video are calculated by calling the interface Md5.create of the Md5 function to splice together their Md5 values, resulting in the data of the first private key.
And 3, calculating the first public key.
ClientPublickey＝RSA.CreatePair(ClientPrivatekey)；
The first public key is generated by calling the generation pairing key interface RSA.
The final server thus generates a pair of first public key and first private key information.
102. The client generates a second public and private key pair;
when the server interacts with the client, the server firstly issues the information of the first public key of the server to the client. Meanwhile, the client generates a pair of second public and private keys in the manner of the server. The server generates a second private key according to the ID number of the current video, the user ID number (user ID, Uid) of the user and the random data, so as to ensure that the private keys of different clients playing different videos are different as much as possible. The concrete implementation is as follows:
step 1, generating random data;
Randdata＝rand()；
and generating a random data Randdata by calling a system function rand.
And 2, generating an Md5 value of the current video as a second private key according to the ID number, the Uid and the random number of the current video.
ServerPrivatekey＝Md5.Create(Randdata+Uid+VideoId)；
And calculating the Md5 value of the random number, the Uid of the user and the ID number of the current video by calling an interface Md5.Create of the Md5 function to splice together, thereby obtaining the data of the second private key.
And 3, calculating a second public key.
ServerPublickey＝RSA.CreatePair(ServerPrivatekey)；
The second public key is generated by calling the generation pairing key interface RSA.
So that the client generates information of the second public-private key pair.
At this time, after receiving the first public key issued by the server, the client sends the information of the second public key to the server.
103. The server and the client exchange public keys and generate a shared secret key;
the server and the client exchange respective public key information to generate a shared key, and it is understood that the shared key generated by the server and the client is the same value. It should be noted that, in order to ensure that the shared keys generated by the server and the client are the same value, the server and the client need to negotiate to determine a generation algorithm for generating the shared key according to the first public key and the second public key before generating the shared key.
The specific server and the client exchange public keys and generate a shared secret key as follows:
and step 1, exchanging public keys.
The server sends the first public key ServerPublinkey of the server to the client.
And the client sends the second public key ClientPublinkey of the client to the server.
And step 2, the client generates a shared secret key.
ShareKey＝RSA.CreateShareKey(ServerPublickey,ClientPrivatekey)；
And 3, the server generates a shared secret key.
ShareKey＝RSA.CreateShareKey(ClientPublickey,ServerPrivatekey)；
Since the generation factor and the generation algorithm are consistent, the values of ShareKey generated by the server and the client are consistent.
It should be noted that the client generates the shared key through step 2, and the server generates the shared key through step 3, and these two processes are not limited by a time sequence, that is, step 2 may be executed first, step 3 may be executed first, or executed simultaneously, and the specific details are not limited herein.
After the server and the client generate the shared secret key, the server and the client are encrypted or decrypted according to the shared secret key. Optionally, in this embodiment of the application, in addition to performing encryption or decryption processing by using an asymmetric RSA encryption algorithm, a Data Encryption Standard (DES) or another encryption algorithm may also be used, which is not limited herein.
104. The server adds verification information into each video of the live broadcast platform respectively;
for all videos of the live broadcast platform, the user uploads the produced videos to the server, the server verifies each video, and the watermark of the live broadcast platform is added into each video to prevent other platforms from stealing the video. After the video is added with the watermark, the server respectively adds the verification information into each video of the live broadcast platform, and the verification information does not influence the playing of the video and only plays a verification role, namely the verification information is used for identifying the client of the live broadcast platform.
It should be noted that the verification information added by the server in each video may be different, for example, the server may generate the verification information uniquely corresponding to each video according to the identification Information (ID) of each video; alternatively, the server may also generate a unique character string for each video, for example, randomly generate a 128-bit or 256-bit character string for each video, and use the character string as the corresponding verification information for each video. Therefore, the way in which the server generates the verification information is not limited herein.
105. The client obtains video information of a current video;
when a user watches a current video through a client, the client can download video information of the current video, wherein the video information of the current video carries verification information of the current video.
106. The client generates a client calculation result according to the verification information in the video information;
after the client obtains the verification information of the current video, the client calculates to obtain a client calculation result according to the verification information of the current video, and the specific implementation manner can be as follows:
Md5result＝md5.create(data+deviceid+token+time)；
the method comprises the steps that Md5result is used for representing a calculation result of a client, md5.create is an interface of an Md5 algorithm, data is verification information in a current video, deviceid represents a unique id of equipment of the client, and deviceid of each user is different; the token is issued by the server when the client logs in, and the time represents the current timestamp information of the client.
107. The client sends a client calculation result to the server;
and after the client calculates and obtains a client calculation result, encrypting the client calculation result according to the shared secret key, and sending the encrypted client calculation result to the server. In the embodiment of the present invention, an encryption algorithm, such as an Advanced Encryption Standard (AES) algorithm, may be used to encrypt the calculation result of the client, which is specifically implemented as follows:
encryptData＝Aes.Encrypt(Md5result，ShareKey)；
the encryptData is used for representing the encrypted client computing result, the Md5result is used for representing the client computing result, and the ShareKey is used for representing the shared secret key.
Optionally, in this embodiment of the present invention, steps 101 to 103 are optional steps, that is, the server and the client may not generate a shared key, and when the client encrypts the client calculation result, in addition to encrypting with the ShareKey, the client may also use a random number that is randomly generated by the server to the client each time the client logs in, so that a specific manner of encrypting the client calculation result by the client is not limited here.
108. The server receives the calculation result of the client according to the shared secret key;
and after receiving the encrypted client calculation result, the server decrypts the encrypted client calculation result to obtain the original client calculation result.
Specifically, the server may also perform a decryption operation on the encrypted client calculation result by using an AES algorithm, which is specifically implemented as follows:
Md5result＝Aes.decrypt(encryptData，ShareKey)；
therefore, the server receives the encrypted client computing result and decrypts the client computing result according to the shared secret key to obtain the original client computing result.
Correspondingly, when the client encrypts the client calculation result by using the random number randomly generated by the server for the client during each login of the client, the server also performs a decryption operation by using the random number randomly generated, and therefore, a specific manner of performing the decryption operation on the client calculation result by the server is not limited herein.
In addition, only the client of the live broadcast platform decrypts the verification information, and the clients of other non-live broadcast platforms do not know that a piece of verification information exists and how to calculate the calculation result of the client, so that the server can determine that the current video watching record is a false record when the client does not report the calculation result of the client.
109. The server generates a server calculation result according to the video data;
it should be noted that the server has the entire video content of the current video, so the server also performs MD5 calculation according to the calculation method of the client, thereby obtaining the server calculation result, and the specific method for obtaining the server calculation result is similar to that in step 106, and details thereof are not repeated here.
It should be noted that, the server generates the server calculation result through step 109, and the client generates the client calculation result through step 106, and these two processes do not have a specific timing relationship, that is, step 109 may be executed first, step 106 may be executed first, or the two processes may be executed simultaneously, and the specific process is not limited herein.
110. The server determines whether the calculation result of the client side is consistent with the calculation result of the server; if not, go to step 111; if yes, go to step 112;
after obtaining the client calculation result and the server calculation result, the server compares whether the client calculation result is consistent with the server calculation result, and if the client calculation result is inconsistent with the server calculation result, the step 113 is executed; if the client-side computation result is consistent with the server computation result, step 114 is executed.
111. The server determines that the record of the current video to be watched is a false record;
when the calculation result of the client is inconsistent with the calculation result of the server, which indicates that the calculation of the client has a problem, the record of currently watching the video is determined to be a false record, namely the current playing of the current video does not count within the watching times of the current video.
112. The server determines that the record currently watching the current video is a legal record.
When the calculation result of the client is consistent with the calculation result of the server, it can be considered that there is no problem in the calculation of the client, and the client plays the current video really, and then it is determined that the record of currently watching the video is a legal record, that is, the playing of the current video is counted in the watching times of the current video.
It should be noted that, in the embodiment of the present invention, in addition to identifying the spurious playback of the video by using the information processing method shown in fig. 1, the spurious playback of the video may also be identified by using the following method, for example:
mode 1: the server and the client may negotiate a shared key that is used to encrypt or decrypt communications between the server and the client. The server obtains video data such as random data Rdata, starting frame data startFrame, frame number NumFrames needing to be calculated and current timestamp information according to a current video played by the client; the server sends the video data to the client, so that the client performs calculation according to the video data to obtain a client calculation result, specifically, the client performs MD5 calculation on the video data according to the starting frame number of the current video and the frame number required to be calculated, and meanwhile, random data Rdata sent by the server is added during calculation, thereby ensuring that the finally calculated client calculation results are inconsistent even if the starting frame number and the frame number are the same. The concrete implementation is as follows:
md5result ═ Md5.create (video _ data + Rdata); wherein Md5result is used for representing the calculation result of the client, and video _ data is used for representing the video data from the starting frame to the frame number of the video; the Rdata is used for representing random data issued by the server. Therefore, the result data of the HASH, i.e. the calculation result of the client, is finally obtained through the md5 algorithm, and the client encrypts and sends the calculation result of the client to the server by using the shared key. The server receives a client calculation result sent by the client and decrypts the calculation result by using the shared key; and when the client side calculation result is different from the server calculation result, the server determines that the current video watching record is a false record.
Mode 2: the method includes the steps that acquisition information is obtained in a client periodically (the acquisition information comprises a watched video number, a unique uid of a user, opening time of a starting frame when a video is watched, a code rate of a current video, an FPS of a current video playing, hardware decoding of the video, software decoding, recording of a video watching state (whether errors occur or not, whether a pause phenomenon exists or not), watching duration of the video, and the total amount of downloaded video stream data in the whole watching duration), for example, the acquisition information is acquired every 1 minute by taking 1 minute as a boundary, and the acquisition information is reported to a server by using an encryption algorithm negotiated by the client and the server. Therefore, any third party platform that steals the video stream (the third party platform uses a general or third party platform's own video player) or does not watch the video will not have the capture information. Meanwhile, for hackers, the collected information in the text is the encrypted collected information (an encryption algorithm is encrypted by a shared secret key negotiated by a client and a server, and the encryption of the collected information depends on time and unique information of users, so that the collected information is forged by copying the data, the server can identify that the collected information is illegal by decrypting the collected information, and meanwhile, even if the collected information is intercepted, the hackers cannot acquire the shared secret key and cannot decrypt the collected information), so that the collected information is not easy to forge and intercept.
Furthermore, in order to interfere cracking or hackers, the data acquisition information of the plaintext can be reported regularly, the plaintext data acquisition mainly comprises part of information which is not particularly important, the aim is that the data acquisition information is plaintext, and hackers can easily find the data acquisition information, so that the hackers can identify the stealing behavior by reporting the data acquisition information of the plaintext according to the text. The data acquisition information may include unique ID information of the current user equipment, current viewing duration information, ID information of a currently viewed film, and current viewed video bitrate information. This data collection information is mainly used to disturb hackers.
It should be noted that, the video stream traffic data downloaded by the client end reported by the present invention can very well identify the behavior of the embezzlement, and when a video of, for example, 10 minutes is watched normally, the content of the video stream needs to be within a reasonable range of video traffic, and the video stream is illegal if the video stream is not within the range, and even if a hacker embezzles the embezzlement, the hacker needs to have a very large network bandwidth to swipe a large number of false watching times, so that the hacker has a very high cost. Therefore, the user who steals the video watching times can be well identified through the information in the text.
Mode 3: it will be appreciated that for a normal user, the frequency with which he or she simultaneously views video is limited. For hackers, in order to forge a large number of viewing records, they would need to swipe the viewing records a large amount to gain revenue. The client obtains verification data through a certain amount of calculation, wherein the calculation of the verification data consumes CPU resources of the client, so that when the client concurrently watches videos, a large amount of calculation needs to be performed concurrently to consume the CPU resources, the concurrent number is limited, and the behavior of refreshing watching times of the client can be prevented. For normal users, normal watching of one-time video does not affect users, and concurrent watching of a large number of videos has great influence, so that the cost is increased. How to design the algorithm can enable the client to have a certain amount of calculation to obtain the verification result, and the calculation cannot be bypassed, and meanwhile, the server can easily judge whether the result of the client is correct. The invention designs a set of algorithm to make the client have a certain amount of calculation, and the server is easy to identify the result of the client and does not consume the calculation resource of the server. First, the client and the server negotiate a shared key, and then the server generates a random string of 32 bits in length and a number of 0 s. These 2 data are eventually sent to the client. And encrypted with the previously negotiated shared key. After receiving the data of the server, the client decrypts the data of the server to obtain the random data character string and the number digit of 0 of the result data needing to be calculated. The client writes an algorithm to generate the result data needed by the server. The client side calculation includes that the unique device ID of the client side, the TOKEN data used when the client side logs in, the unique video ID watched at the client side currently, the random data issued by the server and the current system timestamp information are spliced together, and the random data of the client side is added to calculate the MD5 value, and the specific implementation mode is as follows:
md5result (devicid + Token + videoId + rdata + Time + clientRandData); wherein DeviceId is the device unique ID of the client; wherein, Token is the Token value when the client logs in the server; the videoId is the unique id of the video; rdata is random data issued by the server; the clientRandData is random data generated by the client. The HASH result data is finally obtained by the md5 algorithm, and the server will request the number of 0 at the beginning in the HASH result data calculated by the client. For example, it is calculated as "2013 dabcd6987abc 4523654123451263". Since the first bit of the result data is 2 instead of 0, the client needs to generate random data to calculate the MD5 value until the start bit is 0, so as to satisfy the requirement of the server. Therefore, the calculation amount of the client is the same as that of continuously generating random data and continuously calculating the MD5 value until the requirement of the server is met. The server may also adjust the computation amount of the client, for example, the greater the number of initial 0 s, the greater the computation amount of the client. Making client computation very complex. And after the client end completes the calculation of the result meeting the server, the result data and the data which the client end participates in the calculation are sent to the server. Then Md5result + DeviceId + Time + clientRandData are included. While other data includes the video unique ID and the token server itself has a record at login. The server verifies the client computing result. The client reports the result data meeting the server to the server, and the server checks according to the client data. Md5result (devicid + Token + videoId + rdata + Time + clientRandData); and judging whether the Md5result is consistent with that of the client or not, judging whether the initial number of 0 is satisfied or not, and if so, indicating that the result of the client is correct. And the server only needs to calculate the MD5 value once to know whether the result of the client is correct, because the client frequently calculates the MD5 value to obtain a proper random data clientrRandData, and the server knows the random data selected by the client from the result reported by the client, so that the server verification is simpler.
