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 invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
Referring to fig. 1, a flowchart of a possible information processing method according to an embodiment of the present invention 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 the embodiment of the present invention, 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 sends first indication information to the client;
after both the server and the client obtain the shared secret key, the server sends a first indication message to the client according to the shared secret key, wherein the first indication message is used for indicating the client to send the acquisition information of the current video played by the client to the server at intervals of a first preset period according to the shared secret key, namely the server encrypts the first indication message according to the shared secret key to obtain encrypted first indication information, and sends the encrypted first indication information to the client. In the embodiment of the present invention, an encryption algorithm, such as Advanced Encryption Standard (AES), may be used to perform encryption.
105. The client encrypts the acquired information according to the shared secret key to obtain the encrypted acquired information;
since the player of the video website is developed by the video website, if the player is a normal client, the player must be watched by the video player of the video website, and thus the normal client has the functions of receiving the video data of the server and decrypting the video data. Therefore, after receiving the first indication information, the client decrypts the first indication information according to the shared secret key to obtain the original first indication information.
And the client acquires the acquisition information of the current video played by the client once every a first preset period according to the first indication information, wherein the acquisition information includes but is not limited to one or more of the following information: the video number of the current video, the unique uid of the user, the opening time of the initial frame when the current video is watched, the code rate of the current video, the FPS of the current video playing, the hardware decoding and the software decoding of the current video, the state record (such as whether an error occurs or not, whether a pause phenomenon exists or not) of the current video watching, the watching time length of the current video or the total amount of the downloaded video stream data in the whole watching time length. The first preset period may be 1 minute, or 30 seconds, or 10 seconds, and the like, which is not limited herein. For example, when the first preset period is 1 minute, the client acquires the acquisition information every 1 minute.
After the acquisition information is acquired, the client side encrypts the acquisition information by using an encryption algorithm negotiated by the client side and the server through a shared secret key to obtain the encrypted acquisition information.
106. The client sends the encrypted acquisition information to the server;
and after the client side obtains the encrypted acquisition information, sending the encrypted acquisition information to the server, so that the server decrypts the acquisition information according to the shared secret key to obtain the original acquisition information.
107. The server sends second indication information to the client;
further, in order to interfere with cracking or hackers, the server sends second indication information to the client according to the shared secret key, wherein the second indication information is used for indicating the client to send the plaintext acquisition information of the current video to the server at intervals of a second preset period, that is, the server encrypts the second indication information according to the shared secret key to obtain encrypted second indication information, and sends the encrypted second indication information to the client. In this step, an encryption algorithm such as AES may also be used for encryption.
108. And the client sends the plaintext acquisition information to the server.
And after receiving the second indication information, the client decrypts the second indication information according to the shared secret key to obtain the original second indication information.
And the client acquires the clear text collection information of the current video played by the client once every second preset period according to the second indication information, wherein the clear text collection information may include some less important information, such as but not limited to one or more of the following information: the unique ID information of the current user equipment, the watching duration information of the current video, the ID information of the current video or the video code rate information of the current video. The second preset period may be 1 minute, or 30 seconds, or 10 seconds, and the like, which is not limited herein. For example, when the second preset period is 1 minute, the client acquires the plaintext acquisition information every 1 minute.
It should be noted that the purpose of collecting the plaintext collected information is to interfere with a hacker, and since the plaintext collected information is plaintext and is not encrypted, the hacker can easily find the plaintext collected information, so that the hacker can recognize the hacking behavior by reporting the plaintext collected information for the server.
Therefore, after the client acquires the plaintext acquisition information, the plaintext acquisition information is directly sent to the server.
109. The server determines whether the current video watching record is an illegal record according to the encrypted acquisition information;
and after obtaining the encrypted acquisition information, the server decrypts the acquisition information according to the shared secret key to obtain the original acquisition information. It should be noted that, if any third-party platform steals the video stream (the third-party platform uses a general or own video player) or does not view the current video, the acquisition information will not be available. Meanwhile, for hackers, the acquired information is encrypted acquired information, the encryption algorithm is encrypted by a shared secret key negotiated by a client and a server, the encryption of the acquired information depends on time and unique information of users, the acquired information is forged by copying the data, the server can identify that the acquired information is illegal by decrypting the acquired information, and even if the acquired information is intercepted, the hackers cannot acquire the shared secret key and cannot decrypt the acquired information, so that the hackers cannot forge and intercept the acquired information easily.
It should be noted that, when the collected information includes the video stream traffic data downloaded by the client, the behavior of the pirate is very well recognized, and for example, when a video of 10 minutes is watched normally, the video must be within a reasonable preset video traffic range, and is illegal if the video is not within the range, and even if a hacker performs the pirate, the hacker must 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.
In addition, if the server determines whether the current video watching record is an illegal record, the current video playing is not counted in the watching times of the current video; and if the server determines that the current video watching record is a legal record, the current video playing time is counted in the current video watching times.
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: for all videos of the video website, the user uploads the prepared videos to the server. The server firstly audits the video and adds the watermark of the video website into the video to prevent other websites from stealing the video. Therefore, in the invention, after the video is added with the watermark of the video website, a path of verification information is further added to the video, and the verification information is not played but only plays a verification role. And when inserting information, the invention makes the inserted information of each video different according to a certain algorithm. When the user terminal watches the video, the video content is downloaded, wherein the video content carries the verification information, only the player of the video website can decrypt the verification information, and the verification information is calculated to obtain a verification result and reported to the server. For other players of non-video websites, the player does not know that there is a piece of authentication information, and does not know how to calculate the authentication result, so that the server can identify and obtain the real watching times watched through the player of the video website.
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 0s, 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.
