Description:
FIELD OF THE TECHNOLOGY 
     The present invention relates generally to data processing and transmission technologies, and more particularly, to method, system and server for managing data transmission. 
     BACKGROUND OF THE INVENTION 
     Along with the development of information technology, the Internet has entered into the people&#39;s work, study and life, and brought great advantages for people&#39;s communication. Generally, a network system consists of servers and clients. 
     Refer to  FIG. 1  which is a schematic diagram illustrating a network system. The system consists of server  910 , a first client  920  and a second client  930 ; wherein, the first client  920  and the second client  930  both have a data channel with Server  910 , the first client  920  may also directly exchange data with the second client  930 . 
     In a network system, a user usually identifies itself using some manners, for example an image provided by an instant communication system. This image for indicating a user identity is also called a head-image. 
     Refer to  FIG. 2  which illustrates a conventional method described for providing a user with a head-image. The method comprises the following steps: 
     Step S 100 : a server sends to a first client and a second client a series of fixed images which are displayed to users for choosing an image; 
     Step S 110  and Step S 120 : the first client and the second client save the fixed image sequence respectively. 
     Step S 111 : the user of the first client selects an image as its head-image from the series of images provided; 
     Step S 112 : the first client sends the head-image setting information (an image index number) to the server; 
     Step S 113 : the server saves the head-image setting information. 
     When a user of the second client views the user information of the first client, Step S 121  is performed, i.e. the second client sends a request to the server for the user head-image index information, i.e. the head-image setting information, of the first client; 
     Step S 122 : the server receives and resolves the request information; 
     Step S 123 : the server sends the user head-image setting information to the second client; 
     Step S 124 : the second client displays a corresponding image according to the head-image setting information. 
     In this method, the server provides a series of fixed images, and a user only can select a favorable one from such images as his head-image, which impacts experience of the user. Along with the deployment of network communication, fixed system head-images are unable to meet requirements increasingly. 
       FIG. 3  illustrates the conventional method for implementing a personalized head-image. Referring to  FIG. 3 , when a first client communicates with a second client, the method includes the following steps: 
     Step S 211 : user of the first client selects his personalized head-image which is directed to an image taken by a user using a digital camera or found from the Internet, selected by a user. 
     Step S 212 : the first client notifies the second client the head-image is changed by sending a head-image change message. 
     Step S 213 : the second client receives and resolves the head-image change message. 
     Step S 214 : the second client requests the first client to send an image file of the changed head-image. 
     Step S 215 : upon receiving the head-image file request of the second client, the first client sends an image file to the second client. 
     Step S 216 : the second client changes and displays the head-image of the opposing party according to the received image. 
     since a user selects a personalized image optionally, the selected image file may infringe others&#39; intellectual property rights (for example the rights of copyright); and since the image file is transmitted between clients in a Point-to-Point (P2P) manner, it is difficult for the network system to determine whether the image selected by the user has infringed others&#39; intellectual property rights, which makes it impossible to protect the intellectual property rights of image file effectively. The same problem also occurs in the embodiment as shown in  FIG. 2 , since a series of fixed images are saved in the client in the embodiment as shown in  FIG. 2  and the server side only manages the index of image, the server is unable to manage the propagation path of images and to determine whether the image selected by the user has infringed others&#39; intellectual property rights, which makes it impossible to protect the intellectual property rights of image file effectively. 
     Likewise, it is impossible to protect the intellectual property rights effectively when other data, for example ring tone, music, literature to be protected by the intellectual property rights, are transmitted between clients of network system in P2P manner. 
     SUMMARY OF THE INVENTION 
     Embodies of the present invention provide method, system and server for managing data transmission, which may control the propagation path of personalized data effectively. 
     The technical scheme of the technical problem solved by the present invention is given as follows. 
     A method for managing data transmission includes: 
     requesting, by a client, a server for data update; 
     resolving, by the server, the request of client, taking control measurement to the data that the client requests to be updated according to a predetermined control policy, and determining whether the data that the client requests to be updated meet the control policy; 
     if the the data that the client requests to be updated meet the control policy, notifying, by the server, the client of updating data; 
     updating, by the client, the data. 
     A system for managing data transmission includes a server and client; a data channel is set between the server and the client; the server is used for resolving the data update request of client, performing the control measure for the data requested by the client to update according to a predetermined control policy, and allowing the client for update the data after the data requested by the client for update meets the control policy. 
     A server for managing data transmission, comprising: 
     a database for storing the control policy data;
