Detailed Description
The embodiment of the application provides a method and a related device for obfuscating data, which are used for improving privacy and safety of live platform data.
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 method for obfuscating data according to an embodiment of the present application includes:
101. the live broadcast platform server groups the users in the live broadcast room to obtain a plurality of user groups;
for some live broadcast rooms with a large number of people, the number of people can cause too many messages, so that the users cannot watch live broadcast contents, and therefore the users can be grouped in the embodiment of the application. For example, the number of users greater than 2 ten thousand may be divided into 2 ten thousand groups, and if the number of users in the live broadcast room is 10 ten thousand or more, the number may be divided into at least 6 user groups.
The live broadcast platform server divides the users of the live broadcast rooms into groups to obtain a plurality of user groups, the user groups respectively correspond to the grouped live broadcast rooms, and gift information displayed in the grouped live broadcast rooms is different.
It should be noted that, in order to prevent a hacker from obtaining revenue data of a live broadcast room, in the embodiment of the present application, a user of each group can only receive gift information of the group, and viewers of other groups cannot view the gift information, so that a client corresponding to the user of the group cannot count all the gift information of other groups.
102. The live broadcast platform server determines repeated gift information according to a preset algorithm;
in addition, in this embodiment of the application, in order to prevent a hacker from obtaining all gift information by entering one audience for each group, the live broadcast platform server may determine the duplicate gift information, so that the duplicate gift information is displayed in at least two group live broadcast rooms, where the number of displays and the groups among which the display is performed, which is not limited in this embodiment of the application. Specifically, the manner in which the live platform server determines the repeated gift information includes: the live broadcast platform server judges whether the value of the gift information is greater than a value threshold value; and if so, determining that the high-value gift information is the repeated gift information so as to display the high-value gift information in each group of live rooms, wherein the high-value gift information is the gift information with the value larger than the value threshold value.
If the value of the gift information is smaller than the value threshold value, the live broadcast platform server acquires the type and the quantity of the small-value gift information, wherein the small-value gift information is the gift information with the value smaller than the value threshold value; the live broadcast platform server sorts the small-value gifts according to the gift value values and sequentially stores the small-value gifts into a gift array; the live broadcast platform server determines the repeated gift information and the grouped live broadcast rooms to which the repeated gift information is delivered according to the room number, the current date, the type and the number of the small value gift information and the gift arrays of all the grouped live broadcast rooms. It can be understood that the strategy of the application can be different for each room according to the room number of the grouped live broadcast room, so that a hacker can hardly know the rule; the types and the number of all the small-value gift information are acquired, so that the algorithm can be changed if new gifts and numbers are added, and more application scenes can be adapted; and at the current date, the number of days can be accurate, so that the algorithm of the method can be changed every day, and a hacker can difficultly find out the rule. In this embodiment, the specific algorithm may be as follows:
Seed＝sha-128.create(roomid+Time+Gifttype_array+giftnum)；
wherein Seed is used for representing Seed data, roomid is used for representing the room number of a grouping live room, Time is used for representing the current date, Gifttype _ array is used for representing a gift array, and giftnum is used for representing the number of small-value gift information. Therefore, based on the room number, the current date, the number of low value gift information, and the gift array, a hash value Seed may be calculated as Seed data for the subsequent selection of the type of gift and the number of deliveries.
It should be noted that Seed is 128 bytes of data, and the gift type of the repeated gift information can be determined by the following formula in this embodiment: gitfttype x ═ Gifttype _ array [ seed [ x-1 ]% giftnum ];
wherein Gitfttype x is used to indicate the gift type of the duplicate gift information, and Seed [ x-1] is used to indicate the xth bit data of Seed. The gift type can be selected from all gift types as the gift type of the repeated gift information through the formula for determining the gift types, the gift types are continuously changed each time the gift types are selected, the variability is better, and a hacker can hardly perceive the regularity to crack the gift.
For example, the first and second data of Seed may be selected as the type of duplicate gift information, i.e.,
Gitfttype1＝Gifttype_array[seed[0]％giftnum]；
Gitfttype2＝Gifttype_array[seed[1]％giftnum]；
in addition, in this embodiment, the last data of Seed may be used as the selection number, where the selection number is the number of types of the repeated gift information, and the calculation method may be as follows:
Selectnum＝seed[127]％giftnum；
where Selectnum is used to indicate the number of selections and Seed [127] is used to indicate the last bit of Seed.
After determining the gift type, the live broadcast platform server needs to determine which packets the repeated gift information is repeatedly sent in, wherein in this embodiment, the packets may also be determined by using Seed data, that is, a packet live broadcast room where the repeated gift information is delivered is determined, which is specifically implemented as follows:
Team y＝seed[y+100]％teamnum；
team y is used for representing each group of live broadcast rooms, and Team num is used for representing the total number of groups; when the Team y is not equal to the Team y +1, the live broadcast platform server determines that the Team y +1 is a grouping live broadcast room where the repeated gift information is delivered, so that the gift information with the gift type of Gitfttype x in the Team y is repeatedly displayed in the Team y + 1. For ease of understanding, for example, Team1 ═ seed [100 ]% teamnum, Team2 ═ seed [101 ]% teamnum; reselecting a packet if Team2 is equal to Team 1; if the Team2 is not equal to Team1, the selected gift type of Team1 is repeatedly transmitted at Team 2. In addition, in consideration of the fact that all the duplicate gift information cannot be transmitted to Team2, resulting in excessive gift information of Team2, the present embodiment calculates the gift type of the next duplicate gift information and determines whether the calculated value is in Seed, transmits the duplicate gift information to packet 2 if it exists, and does not perform duplicate transmission if it does not exist.
By the method, even if a hacker monitors the grouped live broadcast rooms of a plurality of groups, the gift messages received by the hacker have a plurality of repeated gift messages, so that the hacker cannot acquire accurate gift revenue data.
In addition, for the small-value gift information in one packet, when the number of gifts in the same time packet is large, the live broadcast platform server may consider discarding part of the small-value gift information, and the specific degradation may use a sliding window manner, for example, calculating the number of small gifts received in one second, setting the maximum number of gifts in one second, and discarding the small-value gift information if the number of small-value gift information exceeds the maximum number of small-value gift information received in one second. The specific algorithm is as follows: first, after receiving gift information, the value of the gift information is judged, if the gift information is high-value gift information, a discarding strategy is not adopted, and only low-value gift information adopts the discarding strategy. In this embodiment, a GiftLimit class is defined, a queue list is designed to store a time when gift information is received, the time is an integer value of time, and the type of the time can be uint64_ t, and then a member variable m _ nLimit storing a threshold value is defined to store the maximum gift number DanmuLimit issued by the live broadcast platform server, where the specific function is implemented as follows:
Class GiftLimit{
std::list<uint64_t>m_item_times；
size_t m_nLimit；
m_nLimit＝DanmuLimit；
and then redesigning interface information of the gift message degradation class. Firstly, acquiring the current time by calling a system function nowtime, storing the current time into a nowvariable, and judging whether the time number in the current queue is greater than a threshold value m _ nLimit or not; if the current time is less than the maximum threshold, the current time now is stored in the queue by calling the push _ back of the list, and the true is returned, which indicates that the gift information can be displayed currently, and the specific function is implemented as follows:
Figure BDA0002186499200000071
Figure BDA0002186499200000081
then, whether the current time and the time at the head of the queue are smaller than 1s, namely a threshold value of 1000ms is judged, if yes, false is returned, otherwise, a function DeleteOlderTime () is called to delete the time exceeding the threshold value of 1s in the queue, and the specific function is realized as follows:
if((now-m_item_times.front())<＝1000)
return false；}
DeleteOlderTime(now)；
}
it should be noted that, since the deletion interface DeleteOlderTime is defined above, in this embodiment, all time values that the time difference between the time in the queue and the time at the head of the queue exceeds a threshold, for example, 1s, need to be deleted, and a manner of implementing the deletion interface includes: writing a loop to traverse the queue, firstly defining an iterator std: list < element 64_ t: iterator iterer; then, the iterator is assigned as the starting iter of the queue, m _ item _ times, begin (); writing a for loop to traverse, judging whether the difference value between the time in the queue and the current time is greater than a threshold value 1000ms, if so, deleting the time from the queue through a deletion function m _ item _ time. If not, indicating that the time of the queue head is less than the threshold value, interrupting the circulation and directly returning, wherein the specific function implementation comprises the following steps:
Figure BDA0002186499200000082
wherein iter! End () represents whether it is the end of the queue.
In this embodiment, since too many gifts are received at the same time, the network performance or other device performance of the client may not handle too many gifts, so discarding part of the small gifts may not only improve the viewing experience of the user, but also prevent hackers from obtaining the quantity and value of all the gifts.
103. The live broadcast platform server determines a hacker client and generates false gift information;
in order to further enhance the interference on the data of the hackers, in the embodiment, the monitoring accounts and the clients of some hackers can be analyzed based on the characteristics of the live broadcast platform, so that some false gift information can be delivered to the clients of the hackers in the following period. The method for determining the hacker client by the live broadcast platform server comprises the following steps:
in order to obtain the income of the live broadcast platform, a hacker needs to log in a live broadcast room by a large number of account numbers, and the live broadcast platform server can search a large number of client sides corresponding to the account numbers under the same IP address by analyzing the IP addresses of the client sides of the account numbers to be used as the hacker client sides. Namely, the live broadcast platform server determines the IP address of each client of the live broadcast platform; if the number of the target clients with the same IP address is larger than a first threshold value, the live broadcast platform server determines that the target clients are hacker clients;
alternatively, the first and second electrodes may be,
for hackers to get all gift data of each live room of the live platform, an account must be entered in each live room, and an account must be within the live room for 24 hours each day that must last. For a normal user, when the main broadcast shows that the live broadcast room is a blank screen, normal audiences can quit the live broadcast room, accounts which do not quit and are online for 24 hours are suspicious accounts, and the client corresponding to the accounts is a hacker client. For normal users, the account numbers can be continuously switched to different live broadcast rooms for watching, the account numbers of hackers cannot be used for switching rooms, and once the rooms are switched, the gift messages are lost, the obtained gift messages are inaccurate, so that the hacker account numbers basically cannot have normal user behaviors such as room switching and the like. Namely, the live broadcast platform server determines the live broadcast room switching times and the online time length when each client of the live broadcast platform is online; and if the online time of the target client is greater than the second threshold and the live broadcast switching time is 0, determining that the target client is a hacker client.
Therefore, in the embodiment of the present application, there are various ways to determine the hacker client, and the details are not limited herein.
In addition, in order to make the income data acquired by hackers inaccurate, the live platform server can also generate false gift information for confusion. The specific implementation comprises the following steps: the method comprises the steps that an identification field is added in gift information and used for indicating whether the information is real gift information or false gift information, the identification field is pre-embedded in a code of a client before a client releases a version, after the client receives the gift information, the identification field of the gift information is judged firstly, if the information is the false gift information, the identification field is directly discarded without being displayed, and if the information is the real gift information, the identification field is displayed. In addition, in order to better conceal the identification field property, before the client releases the version, the live broadcast platform server negotiates with different clients to define a field, the negotiated identification fields of the different clients are different, and the identification field is modified every time a new client version is released, so that the live broadcast platform server needs to release different fields according to different client versions. For example, for windows7.0 version, the live platform server indicates whether the information is false through 1-bit field a, such as 1 indicating real gift information and 0 indicating false gift information; for windows8.0 version, the live platform server indicates whether or not there is false information through a 2-bit field B, e.g., 11 indicates real gift information and 00 indicates false gift information.
It will be appreciated that each modification of the identification field is to prevent a hacker from cracking the identification field and thereby circumventing the false gift message of this embodiment. If the hacker does not know that the false gift information is set, the total gift revenue obtained by the hacker client is an error.
104. The live broadcast platform server obtains the number of target gifts received by each group of live broadcast rooms within a preset time length, and determines a target delivery value corresponding to the number of the target gifts based on the incidence relation between the number of the gifts and the delivery value;
in the embodiment, after the hacker client is determined, false gift information is delivered to the hacker client, and the obtained revenue data of the hacker is wrong due to the false gift information obtained by the hacker client. In order to make the false gift information more authentic, the same false gift type and gift number may be delivered to hacker clients with the same IP address, so that the hackers are not easily aware of it. It can be understood that the false gift information is not easy to be found when the gift information is delivered in a large quantity, so that the live broadcast platform server can calculate the heat degree of the gift information, namely when the gift information received by the live broadcast room in a preset time length is greater than the initial delivery value of the false message, the false gift information is delivered to each client of the live broadcast room; and when the gift information received within the preset time length is smaller than the initial delivery value of the false information, the false gift information is not delivered to each client side of the live broadcast room.
In this embodiment, stepwise delivery multiples may be used, that is, the number of false gifts delivered is set to be different for each class, and in order not to generate regularity, a delivery range may be set and then a number may be randomly selected from the range data. The concrete implementation is as follows:
the live broadcast platform server obtains the starting Time and the current Time through a system function Time (), counts the number of received gifts from the starting Time, pauses the counting when the difference value between the current Time and the starting Time is preset Time length, and takes the number of the gifts counted when pausing as the number of target gifts, and the function implementation can be as follows:
firstly, obtaining a starting Time timestamp through a system function Time (), namely Uint64 timestamp ═ Time (); then setting a variable count for recording the number of gift messages, and initializing the variable count to 0, namely, intcount is 0; when receiving information, judging whether the information is gift information, if so, acquiring current of current time, calculating a difference elapse between the current time and the starting time, and if the elapse is greater than a preset time (such as 1000ms), restarting statistics, namely setting the starting time as the current time and setting the number of the current gifts as 0; if the elapse is less than the preset time length, when the received information is gift information, adding 1 to the value of the variable count until the elapse is equal to the preset time length, stopping the round of statistics, and performing the next round again. The function is implemented as follows:
Figure BDA0002186499200000101
Figure BDA0002186499200000111
wherein, message is used to indicate a message received, type is used to indicate the field type of the message, and gift is used to indicate that the message is gift information.
After counting the number of gifts received within a preset time, the live broadcast platform server determines the value range (num _ min, num _ max) of the target delivery value by the following formula:
num_max＝(count-A)n*k；
num_min＝(count-A)m*k；
wherein num _ max is used for representing the maximum value of the target delivery value, num _ min is used for representing the minimum value of the target delivery value, count is used for representing the number of target gifts, A, m and n are positive integers, A is a false message initial delivery value, n is larger than m, n is positively correlated with the number of the target gifts, and k is a constant used for representing a proportionality coefficient; in addition, different scaling factors may be set based on different live rooms. In practical application, if the number of target gifts in the live broadcast room is larger, the value of k may be smaller. For example, k may randomly take between 0.5 and 2 when count >500, and between 2 and 4 when 400< count < 500.
The value range of the target delivery value is obtained through the formula, the value range is positively correlated with the size of the target gift quantity exceeding the initial delivery value of the false message, namely, the larger the gift sending heat of the live broadcast room is, the more false gift information can be delivered, the more income data obtained by the hacker client can be confused, and the smaller the gift sending heat of the live broadcast room is, the less the delivered false gift information is, so as to avoid being doubted by the hacker client. Meanwhile, the value is randomly selected from the value range to serve as the target delivery value, so that a hacker is more difficult to find the rule, and the security threshold for acquiring the income data of the live broadcast platform is improved.
For the convenience of understanding, when the counted target gift number count is greater than 500, the smallest value of the target delivery value can be calculated by multiplying the square of the number of (count-500) by the scaling factor k, and the largest value of the target delivery value can be calculated by multiplying the cube of the number of (count-500) by the scaling factor k, which is specifically calculated as follows:
Switch(count){
Case count>500:{
Int num_min＝(count-500)*(count-500)*k；
Int num_max＝(count-500)*(count-500)*(count-500)*k；
}
when the counted target gift number count is greater than 400, the number of (count-500) is multiplied by a proportionality coefficient k to calculate the minimum value of the target delivery value, and the square of the number of (count-500) is multiplied by the proportionality coefficient k to calculate the maximum value of the target delivery value, which is specifically calculated as follows:
Case count>400:{
Int num_min＝(count-500)*k；
Int num_max＝(count-500)*(count-500)*k；
since the number of 400 gifts is less than the number of 500 gifts and the expansion factor is less than 500, the maximum data uses the square. Wherein, the proportionality coefficient k can be set based on different live broadcast rooms, and k can randomly take 2.0 to 4.0 direct data according to rooms.
After the value range (num _ min, num _ max) of the target delivery value is determined, an integer value is randomly selected in the value range of the target delivery value through a system function rand () as the target delivery value, and the specific function implementation comprises the following steps: intra — rand (num _ min, num _ max); where num is used to represent the target delivery value.
Therefore, after the target delivery value which is the false gift number needing to be delivered is obtained, the live broadcast platform server can deliver the false gift information of the target delivery value number to the hacker client.
105. Encrypting gift information by the live platform server;
in order to prevent a hacker from easily obtaining the gift information through a network protocol without passing through a client to ensure the security of the gift information, in this embodiment, the live broadcast platform server may encrypt the gift information and then send the encrypted gift information to each client, so that a threshold for the hacker to monitor the gift information may be further increased, and difficulty for the hacker to obtain the full amount of the gift information may be increased. In this embodiment, different encryption algorithms and keys are used based on different client types, so that the live broadcast platform server uses algorithms and keys with different strengths for different clients. The client type can comprise android client, Ios client, Windows client, WEB client and the like. The concrete implementation is as follows:
after the client logs in, the live broadcast platform server and the client negotiate a shared key based on an encryption algorithm, and subsequent information is encrypted and transmitted based on the key. For example, the key may be negotiated using an asymmetric algorithm, that is, the client generates a pair of client public and private keys, the live platform server generates a pair of server public and private keys, and then the client exchanges a public key with the live platform server, the client generates a shared key using a client private key and a server public key, the live platform server generates a shared key using a client public key and a server private key, and the shared key of the live platform server and the shared key of the client are the same. The specific implementation function is as follows:
generating a client private key, namely ClientPrivatekey ═ RandData, by using random data, wherein the ClientPrivatekey is used for representing the client private key; then, according to the client private key, an asymmetric algorithm Ecc is used to generate a client public key, namely clientpublic key ═ eccencryption. createpair (clientprivate key), wherein the clientpublic key is used to represent the client public key; similarly, the direct broadcast platform server adopts the same algorithm to generate a server private key serverpivatekey and a server public key ServerPublickey. After the generation, the live broadcast platform server sends a server public key ServerPublinkey to the client and receives a client public key ClientPublinkey sent by the client, the client and the live broadcast platform server respectively generate shared keys, and the function expression is as follows:
the client generates a shared key:
ShareKey＝EccEncryption.CreateShareKey(ServerPublickey,ClientPrivatekey)；
the live broadcast platform server generates a shared key:
ShareKey＝EccEncryption.CreateShareKey(ClientPublickey,ServerPrivatekey)；
after the live broadcast platform server generates a shared key, gift information is encrypted according to the shared key, and the specific functions are implemented as follows:
Encrypt_data＝encrypt(gift_data,ShareKey)；
wherein, gift _ Data is gift information, Encrypt () is an encryption interface, and Encrypt _ Data is used for representing the encrypted gift information. Therefore, the gift information encrypted based on the shared key is received by the client, and can be decrypted by the shared key to obtain the plaintext.
In this step, the live broadcast platform server encrypts the gift information and sends the encrypted gift information to each client, so that the threshold of a hacker for monitoring the gift information can be further improved, and the difficulty of the hacker for acquiring the full amount of gift information is increased.
106. The live broadcast platform server sends the false gift information of the target delivery value quantity to the hacker client in each grouped live broadcast room, and sends the corresponding gift information to all the clients in each grouped live broadcast room;
when the live broadcast platform server determines that gift information received by a grouping live broadcast room in a preset time length is larger than an initial delivery value of false information, the live broadcast platform server sends the false gift information of a target delivery value number to a hacker client in the grouping live broadcast room and sends corresponding gift information to all clients in each grouping live broadcast room, wherein all the clients comprise the hacker client and legal clients, and the gift information comprises repeated gift information.
Optionally, the gift information sent by the live broadcast platform server to all the clients may be gift information encrypted by using a shared key, and then the legal client may decrypt the encrypted gift information by using the negotiated shared key to obtain a plaintext after receiving the encrypted gift information, and the hacker client cannot decrypt the encrypted gift information if the hacker client does not know that the network protocol cannot generate the shared key, so that difficulty in obtaining the revenue data of the live broadcast platform by the hacker client is improved.
107. A legal client self-defines a display control;
108. and the legal client decrypts the gift information and displays the gift information.
It is contemplated that hackers may also take Hook from the display control of the gift information to obtain the gift information, thereby bypassing the encryption algorithm of the gift information. Because the control provided by the system stores all messages and the content of the messages in the attributes of the control and is easily acquired by a hacker, for the security of the gift information, a legal client side can display the gift information by using a customized display control instead, and the customized display control needs to be much secure from the security perspective and different from the control provided by the system, so that the difficulty of acquiring by the hacker is higher. The customized control can be understood as a display control corresponding to self-writing of a legal client, for example, the number display of the gift information is a text control, the system can provide a TextView control to display the text, and in this embodiment, the legal client can customize a TextView control to display the text, and simultaneously encrypt the file content stored in the control, and only decrypt and display the file content when displaying. It can be understood that since the display control is different among different types of clients, a set of display controls needs to be implemented independently among different types of clients. For example, for a windows platform, all the controls are implemented based on the windows, a window may be created, characters may be drawn on the window, and various events of the window may be composed, such as entering a text event, deleting the text event, the window acquiring a focus, and the like. Specifically, in the embodiment of the present application, the manner of customizing the display control by the legal client is as follows:
firstly, a legal client writes a class DataCenter, all data of the control provided by a system are different from the control provided by the system are in one control, for example, all displayed data and data content are in one control, the class DataCenter in the embodiment is used for storing the self-defined control in the text, including all data related to the control and handles of the control, the storage of the data and the use of the data are extracted, and the handles of the control are stored into the class DataCenter, namely a data center, so that the handles and the data in the system TextView are separated, and a hacker cannot acquire the related handles and the data from the system TextView. The specific function is implemented as follows:
Class DataCenter{
HWND_ParentWnd；
HWND_DynamicEdit；
HFONT_Font；
BYTE_RndKey；
String_textdata；
wherein the ParentWnd is used for storing a handle of a parent control of the control; the dynamic edit is used for storing a window handle of the user-defined control; the Font is used for storing the Font of the control; RndKey is used for further encryption key of data, and textdata is text data. It should be noted that if the number of the incoming gifts and the number are encrypted, the data stored in the variable is ciphertext, while the traditional control is written by the system itself, so that the data stored in the traditional control must be plaintext, and the data stored in the text can be in the form of ciphertext by using the custom control.
After the class DataCenter is defined, the incoming control handle is stored into this class.
CDataCenter(HWND ParentWnd，HWND DynamicEdit，HFONT Font){
_ParentWnd＝ParentWnd；
_DynamicEdit＝DynamicEdit；
_Font＝Font；
It should be noted that, when the class data center is constructed, a key is also created for encrypting data, including first setting a seed for generating random data by using a srand () function, so as to make the data different each time, where the srand () function is an initialization function of a random number generator, and randomly generating a key by using a function rand (), so that the key generated by each control is different each time, and then obtaining text data by using a getdata () function and storing the text data by using a temporary variable, where the text data is encrypted data and only needs to be provided to plaintext data to be displayed when the plaintext data is displayed, and the specific implementation function is as follows:
::srand((unsigned)::time(NULL))；
_RndKey＝rand()；。
String getdata(){
String temp＝_textdata；
in addition, when text data needs to be displayed, the stored text data is decrypted to obtain a plaintext to be displayed, in this embodiment, a loop is used to decrypt each text data, and the function is implemented as follows:
Temp[i]^＝_RndKey[i]；
Temp＝decrypt(temp,key)；
Return temp；
}
Void setdata(string data){
Temp＝data；
Temp[i]^＝_RndKey[i]；
}}}
it should be noted that the interface setdata is data set and stored, and when the gift information of the live broadcast platform server is received, the interface setdata is stored in the interface first, and secondary encryption storage is performed, and the key of the secondary encryption is the RndKey randomly generated each time.
Therefore, the constructor of the customized display control in the embodiment of the present application is as follows:
Class TextView:public Window，public DataCenter{TextView(string encryptdata)：DataCenter(encryptdata){textdata＝encryptdata；}
as can be seen by the construction function Class TextView, when a legal client constructs and displays a control, ciphertext characters of the control need to be transmitted in, and are simultaneously stored in the member variable textdata. In addition, in this embodiment, after the display control is customized, a method for responding to the display control is also provided, where the method for responding to the display control is similar to the method for responding to the system control, for example: focus is obtained by LRESULT onset focus (HWND) response, focus is released by LRESULT OnKeyDown (UINT nChar, UINT nRepCnt, UINT nFlags) response button, mouse down is responded by LRESULT OnChar (UINT nChar, UINT nRepCnt, UINT nFlags), mouse down is responded by LRESULT onmouse button down (UINT nFlags, LONG XPos, LONG YPos), mouse etc., and details are not repeated herein.
In addition, for the drawn text of the customized display control, since the data of the customized display control is stored in a ciphertext manner from beginning to end and only a plaintext is transmitted during drawing, the data stored in the display control needs to be decrypted and drawn during drawing, so that the form of the ciphertext is used to the maximum extent, and a hacker cannot acquire plaintext data from the control through the display control. In this embodiment, the interface function OnPaint that the control finally draws may be customized to draw the content of the drawn text to the UI control, specifically including obtaining a window handle that displays the control, where the handle is stored in a class DataCenter, and a background color is set by a SetBkColor () function, a foreground color of a text is set by a SetTextColor () function, and then plaintext data textdata is obtained from the class DataCenter by a getdata () function, and then the text may be drawn by a DrawText () function, and the specific functions are implemented as follows:
LRESULT OnPaint()；HDC hDC＝BeginPaint(CDataCenter->DynamicEdit)；
SetBkColor(hDC,dwBKColor)；
SetTextColor(hDC,dwTextColor)；
String tempdata＝getdata(textdata)；
DrawText(hDC,tempdata,tempdata.length(),&stRect,DT_LEFT|DT_VCENTER)；
it should be noted that, after the rendering is completed, the temporary variable needs to be cleared immediately to prevent the temporary variable from storing decrypted data, including: assigning tempdata as an empty character string, and simultaneously setting the Font through a SelectObject () function because the Font is the Font _ Font acquired from the control center when acquiring the Font, and finally finishing the receipt through an EndPoint () function, wherein the specific functions are realized as follows:
tempdata＝“”；
SelectObject(hDC,DataCenter->_Font)；
EndPaint(Edit,&stPaint)；
}}
in this step, since the display control displays the gift information based on the character string of the ciphertext, the hacker cannot acquire the plaintext data of the display control through the display control or the message function of the display control. Compared with the control provided by the traditional system, a hacker can easily acquire data from the control, and the customized display control in the step can prevent the hacker from finding the message distribution of the control and reading the data of the control to obtain the message and the number of gifts.
Therefore, after receiving the gift information delivered by the live broadcast platform server, if the gift information is sent after being encrypted by the live broadcast platform server, the legal client stores the gift information in the customized display control, and decrypts the gift information by using the shared key for display when the gift information needs to be displayed.
It should be noted that, if the gift information includes false gift information, the valid client confirms that the gift information is not true through the identifier of the false gift information, and directly performs discarding processing without displaying.
The method and the device provide a plurality of strategies including data encryption of gift information, addition of false fields to the gift information, repeated display in each group of live broadcast rooms according to the type and the value of the gift information and the like. Since the legal clients need to compile the analysis of the corresponding gift information and the display of the gift information before releasing the version, the live broadcast platform server cannot modify the functions of the legal clients once the functions of the legal clients are compiled, otherwise, the legal clients cannot parse the files to cause errors. From a security point of view, therefore, the legitimate client needs to have a hot update function, for example, using JS code or other hot update methods. After the legal client has the function of hot update, the live broadcast platform server can continuously change the analysis of the gift information and the field content at regular intervals, the client first receives a new JD code from the live broadcast platform server, and the new JS code contains the analysis of the new gift information. All the strategies of the embodiment can continuously update the strategies without releasing the client version, and the concealment and the safety are improved.
