The obfuscation rule file may be a table file, a text file, or a global variable in the server system program. The server may include at least one confusion rule file, different live broadcast rooms may use different confusion rule files, and preferably, different types of live broadcast room data in each live broadcast room use different confusion rule files. Different confusion rule files are adopted in different live broadcast rooms, and different confusion rule files are adopted in different types of live broadcast room data in the same live broadcast room, so that the difficulty of confusion resolution of the crawler can be improved.
The server may store the confusion rule files corresponding to different types of live broadcast data in each live broadcast by using a Map container, and specifically may store the confusion rule files by using Map < int, fontdata > mapFont, where the key int may be used to store a room number of the live broadcast, and the fontdata may be a structural body representing the confusion rule files. Illustratively, the fontdata structure may be defined as follows:
Struct fontdata{
String fontname1；
Int nData1[10]；
String fontname2；
Int nData2[10]；
String fontname3；
Int nData3[10]；
}；
the fontname can represent the file name of the confusion rule file, and each confusion rule file corresponds to a unique file name; the names of the fontname1, the fontname2 and the fontname3 can be the same or different, namely, the same obfuscation rule file can be selected, or different obfuscation rule files can be selected, and preferably, the three names are different, namely, different obfuscation rule files are selected; and the number of fontname is consistent with the number of data types of the live-air data, namely each data type corresponds to the file name of one confusion rule file, and the number of file names is not limited to 3. Wherein, nData can represent an obfuscated rule file, where the names of fontname1, fontname2, and fontname3 are the same, the obfuscated rule files nData1, nData2, and nData3 are the same, and where the names of fontname1, fontname2, and fontname3 are different, the obfuscated rule files nData1, nData2, and nData3 are also different.
In order to ensure that each obfuscating rule file corresponds to a unique file name, the file name may be obtained by calling a Fontname-md5. create (nData) statement, where the Algorithm for obtaining the file name is not limited to the MD5 Algorithm, but may also be other algorithms, for example, five algorithms of a Secure Hash Algorithm (SHA) family, which are SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512, or may be an MD4 Algorithm or a CRC32 Algorithm, and the like.
Illustratively, the contents of the obfuscation rule file nData may be specifically, 2038694751. Wherein 2038694751 are respectively corresponding to 0123456789. For example, if the obfuscated live broadcast data is 012, the corresponding correct live broadcast data is 203.
The concerned data of the live broadcast room can comprise the number of users and user information of other concerned users in the current live broadcast room; the fan data can comprise the number of users and user information and the like in the current live broadcast room, wherein the users are concerned by other users; the online watching number can be understood as the number of users who watch online when the live broadcast room is live broadcast, wherein the online watching number can be updated in real time; the received gift data may include the type of gift received, the number of each type of gift, etc., and the received gift data may also be updated in real time. When the live broadcast data types include at least two types, the encryption process of encrypting the obfuscated live broadcast data with a high security level once by using the obfuscated live broadcast data with a low security level in the adjacent security levels in step S120 may be performed.
Optionally, the obtaining of the live broadcast data and the obfuscating of the live broadcast data according to the obfuscation rule file include:
acquiring live broadcast room data through a data acquisition interface, wherein the type of the live broadcast room data corresponds to an enumeration element in a preset enumeration object; selecting a confusion rule file corresponding to the enumeration value of the enumeration element, and confusing the live broadcast data of the type corresponding to the enumeration element according to the confusion rule file, wherein the confusion rule file corresponding to the enumeration value of the enumeration element is replaced at preset intervals.
The method includes acquiring live broadcast data through a data acquisition interface, and specifically may be:
Int GetData(int nroomid,int type,int data){}；
wherein, GetData is the name of the data acquisition interface, which is used to represent the data acquisition interface, and the name of the data acquisition interface is not limited to GetData; the system comprises a live broadcast room, a plurality of live broadcast rooms, a plurality of network servers and a plurality of network servers, wherein the nromoid is a room number name of the live broadcast room and is used for representing the room number of the live broadcast room, the room number name of the live broadcast room is not limited to the nromoid, and the room number name of each live broadcast room is different; the type is the type name of the live broadcast data and is used for representing the type of the live broadcast data, and the type name of the live broadcast data is not limited to the type; the data is a live broadcast data name and represents live broadcast data, and the live broadcast data name is not limited to the data.
The live broadcast room data type corresponds to an enumeration element in a preset enumeration object, and specifically may be:
Enum dataType{
edataType_Focus
edataType_Fans
edataType_Noble
}；
the dataType is an enumeration object which can represent a data type contained in a live broadcast room; wherein, the edatatType _ Focus, the edatatType _ Fans and the edatatType _ Noble are enumeration elements in the enumeration object dataType; wherein, the edatatable _ Focus may represent a data type of the data of interest, the edatatable _ Fans may represent a data type of the fan data, and the edatatable _ Noble may represent a data type of the number of nobility of the live broadcast room (i.e., the number of users whose user ratings reach a preset rating among users who watch online in the live broadcast room). The number of the enumerated elements is consistent with the data types of the live broadcast data, namely each data type corresponds to one enumerated element, the number of the enumerated elements is not limited to 3, and the types of the live broadcast data are not limited to the three types. Wherein, the enumeration elements in the enumeration object have fixed enumeration values, the enumeration value of the first enumeration element is 0, the enumeration value of the second enumeration element is 1, and so on, that is, the enumeration values of edataType _ Focus, edataType _ Fans and edataType _ Noble are 0, 1 and 2, respectively. When the server acquires the data type of the live broadcast room, the enumeration value of the data type of the live broadcast room is acquired through the enumeration object immediately. By establishing the corresponding relation between the enumeration value and the confusion rule file nData in the map container, the corresponding confusion rule file nData can be searched in the map container according to the enumeration value, and the live broadcast data of the type corresponding to the enumeration element is confused according to the confusion rule file.
Illustratively, searching a corresponding confusion rule file nData in the map container according to the enumeration value, and obfuscating live broadcast data of a type corresponding to the enumeration element according to the confusion rule file, which may specifically be:
Map<int,fontdata>::iterator itr；
Itr＝mapFont.find(nroomid)；
Int nResult＝0；
If(type＝＝edataType_Focus){
nResult＝(*itr).nData1[data]；
}else if(type＝＝edataType_Fans){
nResult＝(*itr).nData2[data]；
}else if(type＝＝edataType_Noble{
nResult＝(*itr).nData3[data]；
}
Retrurn nResult；
the iterator itr is defined by Map < int, fontdata >: the iterator itr is used for searching the related information of the room number nromomid of the live broadcast room by the searching function mapFine (nromomid) of the Map container; wherein, a result data nResult is defined and used for storing a result value, namely the obfuscated live broadcast data; according to enumeration values corresponding to data types of the different live rooms, namely, edatatType _ Focus, edatatType _ Fans and edatatType _ Noble, different obfuscation algorithms nData can be adopted to obfuscate the data of the live rooms.
By setting the enumeration object, the enumeration value corresponding to the data type of the live broadcast can be obtained, the corresponding confusion rule file nData can be searched from the map container according to the corresponding relation between the enumeration value and the confusion rule file, and the live broadcast data of the type corresponding to the enumeration element is confused according to the confusion rule file. And the confusion rule files corresponding to the data types of the live broadcasting rooms in the live broadcasting rooms can be continuously updated every other preset time, so that the difficulty coefficient of the crawler for confusion resolution of the confusion data is improved.
S120, obtaining the security level corresponding to each live broadcast room data type, carrying out primary encryption on the obfuscated live broadcast room data with high security level by using the obfuscated live broadcast room data with low security level in the adjacent security levels, carrying out secondary encryption on the data subjected to primary encryption by using a preset shared key, and carrying out primary encryption on the obfuscated live broadcast room data with the lowest security level by using the preset shared key.
The security level corresponding to the data type of the live broadcast room can be preset in the server and can be modified according to the service requirement of the live broadcast platform. The method comprises the steps that the obfuscated live broadcast room data with high security level are encrypted once by using the obfuscated live broadcast room data with low security level in the adjacent security level, so that different types of live broadcast room data can be encrypted layer by layer from low to high in order, and the data cracking threshold can be improved by performing associated encryption on the different types of live broadcast room data.
Illustratively, if the live room data types include attention data nFocus, fan data nFans, and noble data nnable, the privacy level gradually increases. Encryption of the obfuscated live room data may be accomplished by:
KEY value acquisition.
HASH calculation of the obfuscated data of interest to obtain KEY1 value, which may be, for example, KEY1 ═ md5.create (nFocus); HASH calculation of the obfuscated fan data yields KEY2 value, which may be, for example, KEY2 ═ md4.create (nFans).
2. Data encryption is concerned after obfuscation.
The obfuscated data of interest is encrypted by using a preset shared key, which may be, for example:
EncryptnFocus＝Tea.Encrypt(nFocus,ShareKey)。
3. and encrypting the vermicelli data after confusion.
The obfuscated fan data is encrypted once by using the KEY1 value, which may be:
EncryptnFans＝Tea.Encrypt(nFans,KEY1)；
the data after the primary encryption is secondarily encrypted by using a preset shared key, for example, the following steps may be performed:
EncryptnFans2＝Blowfish.Encrypt(EncryptnFans,ShareKey)。
4. and encrypting the obfuscated noble data.
The obfuscated noble data is encrypted once with KEY2 value, which may be, for example:
EncryptnNoble＝Rc4.Encrypt(nNoble,KEY2)；
the data after the primary encryption is secondarily encrypted by using a preset shared key, for example, the following steps may be performed:
EncryptnNoble2＝IDEA.Encrypt(EncryptnNoble,ShareKey)。
the HASH Algorithm may be five algorithms of a Secure HASH Algorithm (SHA) family, namely SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512, or other algorithms, such as CRC32 Algorithm. The Encryption Algorithm may be a Tea Algorithm, a Blowfish Algorithm, or an International Data Encryption Algorithm (IDEA), or may also be an Advanced Encryption Standard (AES), a Data Encryption Standard (DES), a Triple Data Encryption Standard (Triple DES, 3DES), and the like, which is not limited herein.
And S130, encrypting the file name of the confusion rule file by using a preset shared key.
For example, the file names Fontname1, Fontname2 and Fontname3 of the obfuscated rule file are encrypted by using a preset shared key, which may specifically be:
encryptname1＝AES.Encrypt(Fontname1,ShareKey)；
encryptname2＝AES.Encrypt(Fontname2,ShareKey)；
encryptname3＝AES.Encrypt(Fontname3,ShareKey)；
similarly, the Encryption Algorithm may be a Tea Algorithm, a Blowfish Algorithm, or an International Data Encryption Algorithm (IDEA), or may be an Advanced Encryption Standard (AES), a Data Encryption Standard (DES), a Triple Data Encryption Standard (Triple DES, 3DES), or the like, which is not limited herein.
And S140, issuing the obfuscated and encrypted live broadcast data and the encrypted obfuscation rule file name to the client so that the client can determine the live broadcast data according to the data issued by the server.
Optionally, the sending the obfuscated and encrypted live broadcast data and the encrypted obfuscation rule file name to the client, so that the client determines the live broadcast data according to the data sent by the server, including:
and sending the obfuscated and encrypted live broadcast room data and the encrypted obfuscating rule file name to the client through long connection, so that the client decrypts the obfuscated and encrypted live broadcast room data and the encrypted obfuscating rule file name to obtain the obfuscated live broadcast room data and the obfuscating rule file name, and downloading the live broadcast room data corresponding to the obfuscated live broadcast room data in the obfuscating rule file corresponding to the obfuscating rule file name through an HTTP interface.
The long connection may be understood as that, after a webpage is opened, a Transmission Control Protocol (TCP) connection for transmitting HTTP data between the client and the server is not closed, and the client may continue to use the established connection when accessing the server again. The live broadcast room data is continuously updated data based on the real live broadcast situation in the live broadcast room, such as the number of people watching online, and therefore, the server can preferably adopt long connection when sending the live broadcast room data.
The client can interact with the server through two interfaces, namely a long connection interface and an HTTP interface, so that the safety of data in a live broadcast room can be enhanced.
Optionally, before acquiring live broadcast data, the method further includes:
the client generates a first public key and a first private key and sends the first public key to the server;
the server generates a second public key and a second private key and issues the second public key to the client;
the client generates a first shared key according to the first private key and the second public key;
the server generates a second shared secret key according to the second private key and the first public key;
the value of the first shared key is consistent with that of the second shared key, and the first shared key and the second shared key are respectively used as preset shared keys of the client and the server.
When a client logs in a server, the server generates a pair of public key and private key information, namely a second public key and a second private key, for the client; meanwhile, the client can also generate a pair of public key and private key information, namely a first public key and a first private key; the client and the server exchange respective public key information, namely the client sends the first public key to the server, the server issues the second public key to the client, the client generates a shared key according to the first private key and the second public key, the server generates the shared key according to the second private key and the first public key, and the two shared keys are consistent in value.
The client can use the random data to generate the first private key, and the first public key is obtained by using the first private key, so that different clients can be guaranteed to correspond to different private keys and public keys as far as possible, and the cracking threshold is improved. The step of generating the first public key by the client may specifically be as follows:
1. random data is generated.
RandData＝rand()；
A piece of random data RandData is generated by calling a system function rand.
2. Random data is used as a first private key.
ClientPrivatekey＝RandData。
3. A first public key is calculated.
ClientPublickey＝EccEncryption.CreatePair(ClientPrivatekey)；
The first public key is generated by calling an Elliptic Curve Cryptography (ECC) generation mating key interface eccencrypt. Besides ECC, other asymmetric algorithms can be used, such as Elgamal algorithm, knapsack algorithm, or RSA encryption algorithm.
When the server detects that the client logs in, the server also generates a second private key and a second public key according to the generation method of the first private key and the first public key, so that different clients are guaranteed to correspond to different private keys and public keys as far as possible, and the cracking threshold is improved. The step of generating the second public key by the server is specifically as follows:
1. generating random data
Randdata＝rand()；
And generating a random data Randdata by calling a system function rand.
2. The random data is used as a second private key.
ServerPrivatekey＝Randdata。
3. A second public key is calculated.
ServerPublickey＝EccEncryption.(ServerPrivatekey)；
The second public key is generated by calling the generating mating key interface eccen encryption of the Elliptic Curve Cryptography (ECC). Besides ECC, other asymmetric algorithms can be used, such as Elgamal algorithm, knapsack algorithm, or RSA encryption algorithm.
The client and the server respectively generate a shared key according to the first public key and the second public key, and the method specifically comprises the following steps:
1. the public keys are interchanged.
And the server sends the second public key ServerPublinkey to the client.
The client sends the first public key ClientPublinkey to the server.
2. The server generates a shared key.
ShareKey＝EccEncryption.CreateShareKey(ClientPublickey,ServerPrivatekey)；
3. The client generates a shared secret.
ShareKey＝EccEncryption.CreateShareKey(ServerPublickey,ClientPrivatekey)；
Wherein, the shared key generated by the server and the shared key generated by the client have the same value of 2 ShareKey. By sharing the key setting, the security of data transmission can be guaranteed.
According to the anti-crawling method for the data in the live broadcast room, the data in the live broadcast room are obfuscated, the obfuscated data are encrypted one time layer by layer according to the confidentiality grade of the data in the live broadcast room, and the obfuscated data are encrypted again by using the shared key, so that the data breaking strength of the live broadcast room can be improved, a crawler is prevented from crawling correct data in the live broadcast room, and the safety of the data in the live broadcast room is guaranteed.
Example two
Fig. 2 is a flowchart of a live broadcast data crawling method according to a second embodiment of the present invention, where this embodiment is applicable to a live broadcast data crawling situation, and the method may be implemented by a terminal, and may be implemented by software and/or hardware in the terminal.
Referring to fig. 2, the method for preventing the live broadcast data from being crawled comprises the following steps:
s210, receiving the obfuscated and encrypted live broadcast data and the encrypted obfuscating rule file name which are sent by the server through long connection;
s220, decrypting the obfuscated and encrypted live broadcast room data and the encrypted obfuscating rule file name to obtain obfuscated live broadcast room data and an obfuscating rule file name;
and S230, downloading live broadcast room data corresponding to the live broadcast room data after confusion in the confusion rule file corresponding to the confusion rule file name through the HTTP interface.
Optionally, decrypting the encrypted obfuscation rule file name includes: and decrypting the file name of the confusion rule file by using a preset shared key.
And the decryption algorithm used for decryption is consistent with the encryption algorithm used by the server for encrypting the confusion rule file. For example, when the server encrypts the confusion rule file, the encryption algorithm used is an AES algorithm, and the decryption algorithm used by the client to decrypt the encrypted confusion rule file name is also the AES algorithm, which may specifically be:
Fontname＝AES.Decrypt(encryptname,ShareKey)。
optionally, decrypting the obfuscated and encrypted live broadcast data includes:
decrypting the confused live broadcast room data with the lowest security level by using a preset shared key;
and carrying out primary decryption on the data subjected to secondary encryption by using a preset shared key, and carrying out secondary decryption on the data subjected to primary decryption with high security level by using the obfuscated live broadcast room data with low security level in adjacent security levels.
And the decryption algorithm used for decrypting the obfuscated live broadcast room data with the lowest security level is consistent with the encryption algorithm used when the server encrypts the obfuscated live broadcast room data with the lowest security level for one time. Illustratively, when the encryption algorithm adopted by the server to encrypt the obfuscated live broadcast room data with the lowest security level for one time is a Tea algorithm, the decryption algorithm adopted by the client to decrypt the obfuscated live broadcast room data with the lowest security level is also the Tea algorithm. Similarly, the decryption algorithm used for the primary decryption of the secondarily encrypted data is consistent with the encryption algorithm for the secondary encryption of the primarily encrypted data by the server by using the preset shared key.
The obfuscated live broadcast room data with the lowest security level can be used for carrying out secondary decryption on the primary decrypted data with the penultimate security level after primary decryption, and the obfuscated live broadcast room data with the penultimate security level can be obtained; similarly, the obfuscated live broadcast room data with the lowest security level from the penultimate end can be used for decrypting the primary decrypted data with the lowest security level from the penultimate end after primary decryption for the second time until all the obfuscated live broadcast room data are obtained, and decryption of the obfuscated and encrypted live broadcast room data is completed.
Illustratively, the data sent by the server and received by the client includes three types, namely primary encrypted interest data encryptnnocus, secondary encrypted fan data encryptnfas 2 and secondary encrypted noble data EncryptnNoble2, wherein the security level is gradually improved. Decrypting the obfuscated and encrypted live-room data may be accomplished by:
1. decrypting the once encrypted obfuscated attention data.
Decrypting the obfuscated data of interest by using a preset shared key may be, for example:
nFocus＝Tea.Decrypt(EncryptnFocus,ShareKey)。
KEY1 value acquisition.
HASH calculation is performed on the obfuscated attention data nCard to obtain a KEY1 value, which may be
KEY1＝Md5.Create(nFocus)。
3. And decrypting the twice encrypted confused vermicelli data.
The second encrypted data is decrypted by using the preset shared key, for example, the following steps are performed:
EncryptnFans＝Blowfish.Decrypt(EncryptnFans2,ShareKey)；
the KEY1 value is used to decrypt the data after the primary decryption for the second time, which may be:
nFans＝Tea.Decrypt(EncryptnFans,KEY1)。
KEY2 value acquisition.
HASH calculation is performed on the obfuscated fan data nFans to obtain KEY2 value, which may be, for example, KEY2 ═ md4.create (nFocus).
5. And decrypting the twice encrypted obfuscated noble data.
The second encrypted data is decrypted by using the preset shared key, for example, the following steps are performed:
EncryptnNoble＝IDEA.Decrypt(EncryptnNoble2,ShareKey)；
the KEY2 value is used to decrypt the data after the primary decryption for the second time, which may be:
nNoble＝Rc4.Decrypt(EncryptnNoble,KEY2)。
optionally, downloading live broadcast room data corresponding to live broadcast room data obfuscated in an obfuscation rule file corresponding to the obfuscation rule file name through an HTTP interface includes:
requesting a confusion rule file corresponding to the file name of the confusion rule file obtained by decryption through an HTTP interface; and inquiring the confusion rule file, and acquiring live broadcast room data corresponding to the confused live broadcast room data.
The client can interact with the server through two interfaces, namely a long connection interface and an HTTP interface, so that the safety of data in a live broadcast room can be enhanced.
Optionally, before the step S210, the method further includes:
the client generates a first public key and a first private key and sends the first public key to the server;
the server generates a second public key and a second private key and issues the second public key to the client;
the client generates a first shared key according to the first private key and the second public key;
the server generates a second shared secret key according to the second private key and the first public key;
the value of the first shared key is consistent with that of the second shared key, and the first shared key and the second shared key are respectively used as preset shared keys of the client and the server.
