Description

共享文件的发布、下载方法及文件共享可控系统 Issued share files, downloading and file-sharing methods controllable system

技术领域 FIELD

[0001] 本发明涉及互联网络文件共享领域,尤其涉及文件共享、下载可控的方法及系统。 [0001] The present invention relates to a file sharing network, and more particularly relates to a file sharing system and method for controlled downloading. 背景技术 Background technique

[0002] 作为客户/服务器模式的重要补充,近年来P2P技术在互联网上的应用日益广泛。 [0002] as a client / server model is an important addition, in recent years the application of P2P technology is used widely on the Internet. P2P网络是一种分布式网络,用户共享他们计算机所拥有的部分资源(处理能力、存储能力、网络连接能力、打印机、文件等),这些共享资源借助于网络,能被其它用户直接访问而无需经过中间实体。 P2P network is a distributed network users to share some of the resources (processing power, storage capacity, network connectivity, printers, files, etc.) that they have a computer, by means of these shared network resources, other users can access directly without having to through intermediate entities. 在此网络中用户既可以是资源提供者Gerver),又可以是资源获取者(Client),因此用户间是一种对等的关系。 In this network the user can be both a resource provider Gerver), you can get a resource person (Client), and therefore between users is a reciprocal relationship. P2P技术充分利用了网络边缘的大量计算机资源,包括分散的存储空间、CPU时间、信息内容等多种资源,从而有效降低集中服务器的负载,提高服务的可用性。 P2P technology takes advantage of a lot of computer resources at the network edge, including a variety of resources distributed storage space, CPU time, content and other information, so as to effectively reduce the load on centralized servers, improve service availability.

[0003] 将每个用户抽象为网络中的一个节点,P2P网络中的各个节点是逻辑对等的,即系统中不再明显区分服务器以及客户端,系统中的各个节点之间可以直接进行数据传输而不需要通过中间服务器。 [0003] Each user abstracted as a node in the network, P2P network each node is a logic or the like, i.e., the system is no longer a clear distinction between the server and the client, can direct data between various nodes in the system transmitted without going through an intermediate server. P2P模式的对等性弱化甚至去除了分布节点对集中服务器的依赖,突破了服务器瓶颈,增强了网络的可扩展性。 Peer P2P mode of distribution nodes or even to weaken dependence on centralized servers, breaking the server bottlenecks, enhanced network scalability in addition.

[0004] 随着P2P (Peer-to-Peer,对等)技术的迅速发展,P2P文件共享如今得到了广泛的普及和应用。 [0004] With the rapid development of P2P (Peer-to-Peer, peer to peer) technology, P2P file sharing is now widely spread and applications. 根据全球知名的ISP流量管理及分析解决方案提供商CacheLogic的统计,在2006年1月,Bittorrent (BT下载软件)、eDonkey (电驴)、Gnutella等P2P共享下载软件所产生的网络流量,已经占据了整个互联网71%的带宽。 According to the world's leading ISP traffic management and analysis solutions provider CacheLogic statistics, in January 2006, Bittorrent (BT download software), eDonkey (eDonkey), Gnutella and other P2P sharing download software generated network traffic, have occupied 71% of the entire Internet bandwidth. 借助这类软件,人们可以轻松地获取全球分布的共享文件。 With this type of software, people can easily get to share files worldwide distribution. 综合这类软件的共享文件管理及维护方面的特点,它们大多使用管理服务器或用超级节点担任集中管理节点,网络具有集中式/半分布式结构。 Integrated document sharing and management characteristics of this type of software maintenance, which is often used as a centralized management server or managed node with the super nodes, the network with a centralized / semi-distributed architecture.

[0005] 用户与管理服务器相连接,并且可以是共享用户与下载用户,其角色区分只在共享或者下载的单向过程中有效。 [0005] Users connect to the management server, and the user may be shared with the user downloading, their roles in distinguishing valid only during one-way sharing or downloaded. 共享用户也可以是其非共享内容的下载用户。 Share users can also download the user non-shared content. 例如图1所示的文件共享系统的操作流程图: For example flowchart of the operation of the file sharing system shown in Figure 1:

[0006] 步骤101和步骤102是共享文件的发布过程: [0006] Step 101 and step 102 are created file sharing process:

[0007] 步骤101 :共享用户向管理服务器发送共享信息,该共享信息包括:共享文件的共享用户网络连接信息、文件名、文件大小、文件摘要(是指对文件按照标准算法处理得到的一段固定长度的数据,不管什么文件,使用相同的消息摘要算法时获得的摘要都是固定长度的(例如128比特),而且不同的文件获得的摘要出现相同的概率非常小,所以可以用作文件标识。常见的算法例如MD5,SHA等。在P2P文件下载中,使用文件摘要的作用是做校验,把获得的文件用消息摘要算法得出结果,然后和发布的摘要比较,即可判断下载的文件是否出现传输错误)、文件分片信息、共享文件的发布时间等。 [0007] Step 101: the sharing user transmits the shared information to the management server, the shared information comprises: shared user network share connection information, file name, file size, file digest (refer to a fixed file according to the standard algorithm processing obtained data length, no matter what the summary file, obtained using the same message digest algorithms are (e.g. 128 bits), and the same probability to obtain different files summary appears fixed length is very small, it can be used as the file identifier. common algorithms such as MD5, SHA, etc. in P2P file downloads using file a summary of the role is to do the check, the documents obtained by the outcome of the message digest algorithm, and then publish a summary of the comparison, you can determine the downloaded file if transmission errors), file fragmentation information, published sharing files and so on.

[0008] 步骤102 :管理服务器以适当的数据结构保存共享用户发布的共享信息。 [0008] Step 102: the management server to save the shared data structure suitable share information posted by users.

[0009] 步骤103至步骤106是共享文件的下载过程: [0009] Step 103 to step 106 is a shared file download process:

[0010] 步骤103 :下载用户向管理服务器发起共享文件查询请求,该请求包括共享文件的文件名;[0011] 步骤104 :管理服务器本地查询,得到一个或多个该共享文件的共享用户网络连接信息; [0010] Step 103: Download user initiates a query request shared file management server, the request including the name of the shared file; [0011] Step 104: a local management server, to retrieve the one or more users to share a network connection to the shared document information;

[0012] 步骤105 :管理服务器向下载用户反馈该一个或多个该共享文件的共享用户网络连接信息; [0012] Step 105: the management server to download one or more user feedback of the user to share the shared network connection information file;

[0013] 步骤106:下载用户与一个或多个共享用户建立连接,开始共享文件传输。 [0013] Step 106: Download user with one or more users to share a connection, shared file transfer begins. 该过程具体为下载用户向一个或多个共享用户发送下载请求,一个或多个共享用户反馈连接请求,开始共享文件传输。 The specific process for downloading a user to one or more users share the download request sent, the one or more users to share feedback connection request, shared file transfer starts.

[0014] 但是这种共享机制由于没有用户管理与控制机制,所以共享文件可以被连接到管理服务器的任何用户查询并下载。 [0014] However, this sharing mechanism because there is no user management and control mechanisms, the shared file can be connected to any queries the user management server and downloads. 为了实现小范围的P2P文件共享与下载,目前可以借助于某些公共的P2P平台,用户自己架设自己私有的非公开的群体内服务器。 In order to achieve a small range of P2P file sharing and downloading, there may be some public by means of P2P platform, users set up their own in-group server nonpublic own private. 群体内的各个成员都将其客户端的P2P接入服务器地址设置为私有的非公开的群体内服务器地址,这样就建立了特定群体的P2P共享平台。 Each member in the group will be its P2P client access server address is set within a private group of private server address, thus establishing P2P sharing platform specific groups. 其操作过程与图1中所示的流程基本相同,只是需要组内成员预先设置私有的非公开的群体内服务器地址,在此就不再累述其共享及下载流程。 During its operation flow shown in FIG. 1 is substantially the same, but need to pre-set group members in closed private server group address, this is not tired and its shared said download process.

[0015] 综上所述,现有技术建设了私有服务器,群体以外的用户无法获知该私有服务器的存在。 [0015] In summary, the prior art construction of a private server, users outside the group can not know the existence of the private server. 但是: but:

[0016] 1、在其成员内部仍然不能实现有效的共享控制,例如在成员内部用户A只想向用户B、C共享文件f这种方式依然是不能实现的,因此现有技术只是在一定意义上实现了文件共享的可控性,并没有真正实现由用户控制的文件共享方式。 [0016] 1, in the interior of its members still can not achieve effective sharing control, such as internal members want user A to user B, C f share files in this way is still not possible, so in a sense just art the realization of the controllability file sharing, file sharing does not really controlled by the user.

[0017] 2、缺乏用户认证平台,容易造成越权的文件访问。 [0017] 2, the lack of user authentication platform, likely to cause unauthorized file access. 例如当该私有服务器地址泄漏, 其他用户就可以连接上来并请求查询和/或下载。 For example, when the leakage of private server address, other users can connect up request and queries and / or download. 在群内成员变动时,共享文件的安全问题就显得更加突出。 When changes within members of the group, the security issues of shared files becomes more prominent.

[0018] 3、用户需要自己架设服务器,这给用户带来了硬件或系统开销。 [0018] 3, the user needs to set up their own server, which gives users a hardware or system overhead. 发明内容 SUMMARY

具体实施方式 Detailed ways

[0040] 本发明实施例的目的是提供一种具有文件访问控制功能的P2P文件共享、下载方法及系统,并在可控的基础上还实现了共享邀请机制。 [0040] The object of embodiments of the present invention is to provide a file access control P2P file sharing function, method and system for downloading and controlled on the basis of the mechanism also enables the sharing invitation. 本发明是通过下述实施例实现的: Embodiment of the present invention is achieved by the following examples:

[0041] 如背景技术中描述的,整个系统中的所有用户既可以是下载共享文件的用户也可以是发布共享文件的用户,其角色区分只在共享或者下载的单向过程中有效。 [0041] As described in the background art, all users in the entire system may be a user to download files shared user can share files are created, their roles in distinguishing valid only during one-way sharing or downloaded.

[0042] 下面首先介绍用户发布共享文件的过程,参见图2,为本发明的网络系统架构图; 该系统包括有登录服务器1、管理服务器2、用户终端3。 [0042] The following first describes the procedure published shared files, see FIG. 2, the present invention is a network system architecture diagram; The system includes a login server, the management server 2, the user terminal 3. 其中管理服务器2中还配置了全局访问控制策略库、策略库用来存储所有用户的标识及对应用户标识在共享控制中需要的信息,并在有用户请求下载共享文件时协助管理服务器进行有效的筛选;用户终端3配置了本地访问控制策略库,负责管理其他用户对共享文件的下载权限。 In which the management server 2 also features a library when the global access control policy, policy repository to store all information about a user's identity and the corresponding user identity needs in a shared control, and a user request to download the shared file server management assistance effective screening; user terminal 3 equipped with local access control policy repository, manages permissions for other users to download shared files. 该网络系统架构在原有集中式/半分布式结构的基础上增加了登录服务器,该登录服务器由服务提供商架设的, 不需要用户自己架设,且该登录服务器可以被所有用户使用。 The network system architecture based on the original centralized / distributed architecture of the half increased the login server, the login server set up by the service provider, users do not need to set up their own, and the login server can be used by all users.

[0043] 实施例1,参见图3,为共享文件发布流程图: [0043] Example 1, see FIG. 3, a flowchart of a shared file distribution:

[0044] 步骤301 :共享用户终端1通过网络向登录服务器发送共享用户1的ID (标识)与共享用户1网络连接信息; [0044] Step 301: the user terminal 1 transmits shared 1 shared user ID (identification) and a shared network connection information to the user registration server via a network;

[0045] 步骤302 :登录服务器验证这些信息是否正确,若正确则共享用户1通过验证,并将管理服务器的网络连接信息发送给共享用户终端1 ;不正确则结束该流程; [0045] Step 302: The authentication server login information is correct, if correct, by sharing a user authentication, and the management server connected to the network sharing information to the user terminal 1; incorrect ending the flow;

[0046] 步骤303 :登录服务器将共享用户1的ID与共享用户1网络连接信息发送给管理服务器;管理服务器将这些信息对应保存; [0046] Step 303: the user login server to share a user ID and a shared network 1 transmits the connection information to the management server; management server corresponding to the stored information;

[0047] 步骤304 :共享用户终端1向管理服务器发送共享文件A的共享文件请求消息,该消息包括:共享用户标识1、共享文件的文件名A、及能够下载该共享文件的用户标识,例如用户2; [0047] Step 304: the shared user terminal 1 transmits a shared file shared file A request message to the management server, the message comprising: a shared user identifier 1, the file name A shared files, and download the user ID of the shared document, e.g. user 2;

[0048] 步骤305 :管理服务器接收该请求,并通过共享用户标识1对应保存共享文件名A 及能够下载该共享文件的用户标识2。 [0048] Step 305: the management server receives the request, and by sharing the shared user identifier 1 corresponding to the file name to save download the user A and the shared file identifier 2.

[0049] 为了能够使用户灵活的控制共享文件的发布时间,在发送共享请求消息时,进一步包括共享文件有效期限;那么管理服务器在接收到该信息时,就只能够在规定的期限内共享该文件,超过规定的期限则取消该文件的共享状态,由于大部分步骤都相同,在此不再累述。 [0049] In order to enable a user to flexibly release time control of the shared document, when sending sharing request message, further comprising a shared file expiration date; then the management server upon receiving the information, can only be shared within a prescribed time limit files exceed the specified time limit to cancel the share status of the file, since most of the steps are the same, this is no longer tired.

[0050] 为了能够在文件共享过程中加强安全性,可以在共享用户1通过登录服务器认证后,由登录服务器生成一个临时密钥,对应于该功能,管理服务器相应的增加了临时密钥集,用以保存所有的临时密钥及接收到用户发送的临时密钥时验证是否合法;用户终端配置的本地访问控制策略库还可以通过临时密钥与下载的用户进行验证。 [0050] In order to strengthen the security of the file sharing process, a user may be shared, a temporary key generated by the login authentication server through the login server, corresponding to the function, the management server adds a corresponding temporary key set, when used to verify the legality of the temporary key and save all received temporary key sent by the user; local user terminal access control policy configuration library can also be verified by the temporary key and download of the user.

[0051] 实施例2,参见图4为增加临时密钥的发布流程图: [0051] Example 2, see FIG. 4 is a flowchart showing a temporary increase in the key released:

[0052] 步骤401 :共享用户终端1通过网络向登录服务器发送共享用户1的ID(标识)与共享用户1网络连接信息; [0052] Step 401: the user terminal 1 transmits shared shared ID (identification) of the user to the login server 1 through a network share a network connection user information;

[0053] 步骤402 :登录服务器验证这些信息是否正确,若正确则共享用户1通过验证,并将管理服务器的网络连接信息发送给共享用户终端1 ;不正确则结束该流程; [0053] Step 402: The authentication server login information is correct, if correct, by sharing a user authentication, and the management server connected to the network sharing information to the user terminal 1; incorrect ending the flow;

[0054] 步骤403 :登录服务器对共享用户1生成一个临时密钥,并将该临时密钥反馈给共享用户终端1 ; [0054] Step 403: the user login server 1 generates a shared temporary key and the temporary key shared feedback to the user terminal 1;

[0055] 步骤404 :登录服务器将共享用户1的ID、共享用户1网络连接信息及共享用户1 的临时密钥发送给管理服务器;管理服务器将这些信息对应保存; [0055] Step 404: the shared server login ID of the user 1, user sharing a network connection information, and shares the temporary key of the user 1 is transmitted to the management server; management server corresponding to the stored information;

[0056] 步骤405 :共享用户终端1向管理服务器发送共享文件A的共享文件请求消息,该消息包括:共享用户标识1、共享文件的文件名A、及能够下载该共享文件的用户标识2、共享用户1临时密钥和共享文件有效期限; [0056] Step 405: the shared user terminal 1 transmits a shared file shared file A request message to the management server, the message comprising: a shared user identifier 1, the file name A shared files, and download the user of the shared file identifier 2, a temporary key shared users share files and expiration date;

[0057] 步骤406 :管理服务器验证该临时密钥是否合法;若是则通过共享用户ID将其他信息对应保存,在共享文件有效期限内设置文件为共享状态。 [0057] Step 406: the management server verifies the legality of the temporary key; if the user ID is shared by the additional information corresponding to the saved setting file in the shared state shared file expiration date.

[0058] 在增加了共享文件安全性的基础上进一步增加其消息传输的私密性,可以在共享用户1发送共享请求的时候使用该临时密钥加密消息;在管理服务器接收到共享用户1发送的共享文件请求时,先将临时密钥解密后再验证临时密钥的合法性,由于大部分步骤都相同,在此不再累述。 [0058] increase the security on the basis of a shared file is further increased privacy message transmission which can be used to encrypt the message when the temporary key shared users sharing a transmission request; received at the management server 1 sends the user's shared when sharing a file request, the first temporary key to decrypt and then verify the validity of the temporary key, since most of the steps are the same, this is no longer tired.

[0059] 在上述实现共享文件发布可控的基础上,还可以在共享管理模块扩展相应的邀请模块,实现共享用户向下载用户发出邀请下载的信息。 [0059] controlled release basis, can also extend the corresponding invitation module in the shared management module in the above file sharing, information sharing user sends an invitation to download user download. 该功能的实现原理是为每个用户ID 建立一个队列,队列中的每个元素包括提供内容并发送共享邀请的邀请者,即共享用户ID, 还包括所关联的共享文件的共享用户网络连接地址。 The principle function of this is to create a queue for each user ID, each queue element comprises providing the shared content sent invitation and the invitee, i.e., shared user ID, further comprising a shared file sharing network connections associated with the user address . 该队列仅保存待发送的邀请事件,一旦某个共享邀请发送到被邀请的用户时,就将该邀请事件从队列中删除。 The queues hold invitation-only event to be sent once a sharing invitation is sent to the invited users to the event invitation removed from the queue. 也就是说如果被邀请的用户在线,就会接收到邀请,该邀请就会从队列中删除,若不在线管理服务器会将该邀请保存,直到用户上线在将该邀请分发并从队列中删除;或者可以设置一定的实现限值, 被邀请用户不在线时,管理服务器保存该邀请超过一定的限值时就将该邀请自动从队列中删除。 This means that if the invited users online, will be receiving the invitation, the invitation will be removed from the queue, if online management server will save the invitation until the user goes online at the invitation distributor and removed from the queue; or you can set certain limits of realization, when the invited user is not online, the management server save the invitation to the invitation automatically deleted from the queue exceeds a certain limit.

[0074] 步骤606 :下载用户终端2向共享用户1发送携带有共享文件名A的下载请求,共享用户1响应该请求,向下载用户2传输共享文件A。 [0074] Step 606: Download user terminal 2 transmits a user to carry the shared downloading request to share the A file name, a shared user response to the request, transmission of the shared files to download the user 2 A.

[0075] 实施例5,对应于实施例2,用户终端配置的本地访问控制策略库还可以通过临时密钥对请求下载的用户进行进一步的身份验证,加强安全性。 [0075] Example 5 corresponds to Example 2, the local user terminal access control policy configuration database may further authenticate the user requests downloading through the temporary key to enhance security. 参见图7为增加临时密钥的下载流程图: Referring to FIG. 7 is a flowchart of downloading additional temporary key:

[0076] 步骤701 :下载用户终端2通过网络向登录服务器发送下载用户2的ID与下载用户2网络连接信息; [0076] Step 701: Download user terminal 2 transmits a download server via the network user to the login ID and the second network 2 to download user connection information;

[0077] 步骤702 :登录服务器验证这些信息是否正确,若正确则下载用户2通过验证并向其反馈管理服务器网络连接信息,不正确则结束该流程; [0077] Step 702: The authentication server login information is correct, if the correct information is downloaded to the second connecting its feedback network management server authenticated the user, the process is ended not correct;

[0078] 步骤703 :登录服务器对下载用户2生成一个临时密钥,并将该临时密钥反馈给共享用户终端2; [0078] Step 703: the login server generates a temporary key to download the user 2, and the temporary key shared feedback to the user terminal 2;

[0079] 步骤704 :登录服务器将下载用户2的ID、共享用户2网络连接信息及共享用户2 的临时密钥发送给管理服务器;管理服务器将这些信息对应保存; [0079] Step 704: The server downloads the login ID of the user 2, user 2 shared network connection information, and shares the temporary key is transmitted to the user management server 2; corresponding to the management information storage server;

[0080] 步骤705 :共享用户终端2向管理服务器发送共享文件A的下载文件请求消息,该消息包括:下载用户标识2、共享文件的文件名A ; [0080] Step 705: the user terminal 2 transmits the shared file A, shared file download request message to the management server, the message comprising: Download user identifier 2, A shared file name;

[0081] 步骤706 :管理服务器接收该请求,查找允许该用户下载的信息;查找到后向下载用户2发送响应消息,该消息包括:共享文件名A、共享文件A的用户标识1、共享用户1的网络连接信息与共享用户1的临时密钥; [0081] Step 706: the management server receives the request, look permission information that the user downloads; send a response message found to download the user 2, the message comprising: a shared file name A, share files A, identifier 1, shared user a network connection with a temporary key shared information 1 of the user;

[0082] 步骤707 :下载用户终端2向共享用户1发送携带有共享文件名A的下载请求,并同时包含下载用户2所获知的共享用户1的临时密钥; [0082] Step 707: Download user terminal 2 transmits a user to carry the shared downloading request to share the file name A and contains the user downloads the learned temporary key shared user 1 2;

[0083] 步骤708 :共享用户终端1在对下载用户2传来的临时密钥验证成功后,向下载用户2传输共享文件A。 [0083] Step 708: After the user terminal 1 shared temporary key download for the user authentication is successful came 2, 2 transmission of the shared files to download the user A.

[0084] 在增加了共享文件安全性的基础上进一步增加其私密性,可以在下载用户2接收到临时密钥后将该临时密钥加密;在共享用户1收到下载用户2发送的下载请求时,先将临时密钥解密后再验证临时密钥的合法性,由于大部分步骤都相同,在此不再累述。 [0084] The temporary encryption key is further increased after increasing its private security based on a shared file, the user may receive downloaded to the temporary key 2; 1 receives the shared user 2 transmits a download request to download the user when, after the first temporary key to decrypt verify the validity of the temporary key, since most of the steps are the same, this is no longer tired.

[0085] 实施例6,对应于实施例3,当下载用户收到邀请下载信息时的下载流程如下: [0085] Example 6 corresponds to Example 3, when the user downloads invitation information downloading download process is as follows:

[0086] 步骤801 :在下载通过登录服务器认证后,判断是否收到邀请下载信息,该邀请下载信息包括:共享用户标识1、共享文件名A、共享用户1网络连接信息等;没有收到则执行步骤802 ;收到则执行步骤803 ; [0086] Step 801: after downloading the authentication server through the log, download information determines whether or not the invitation, the invitation download information comprises: a user identifier sharing, shared file name A, users share a network connection information; is not received performing step 802; step 803 is performed is received;

10[0087] 步骤802 :继续执行与管理服务器常规信息交互; 10 [0087] Step 802: proceed to exchange information with the conventional management server;

[0088] 步骤803 :忽略该请求或者与共享用户终端1建立连接,下载共享文件。 [0088] Step 803: Ignore the request or with the shared subscriber terminal 1, and download the shared files. 如果此时共享用户1已经离线或共享用户终端1已经不共享文件A,则管理服务器可以向共享用户2 返回具有共享文件A副本、且允许其访问的其他用户。 If at this time a sharing user is offline or shared user terminal 1 has not shared file A, the management server may have a shared copy of the shared file A 2 is returned to the user and allow other users to access it.

[0089] 该步骤中所述的建立连接可能是比较复杂的过程,例如需要解密、临时密钥验证等过程,这些过程上述的实施例都已经进行了比较详细的描述,在此不再累述。 [0089] The step of establishing the connection may be a complex process, such as the need to decrypt the temporary key verification process, these processes have the above-described embodiments have been described in detail, this is no longer tired .

[0090] 在实施例4至6中,当下载用户2下载完共享文件A后,可以进一步向管理服务器反馈,管理服务器进一步将下载用户标识2、下载用户网络连接信息、共享文件名A添加到共享文件A的用户信息;或者在下载用户2下载共享文件A的过程中向管理服务器反馈下载用户标识2、下载用户网络连接信息、共享文件名A和下载进度。 [0090] In Examples 4-6, after downloading the user 2 downloads a shared file A, may be further fed back to the management server, the management server further Download user identifier 2, download the user network connection information, shared file name A is added to a file sharing user information; or download the user feedback process 2 a shared file downloaded to the download management server a user identifier 2, the user downloads the network connection information, and shared file name a download progress. 管理服务器在收到上述的反馈后通知其他下载文件A的用户,提高其他下载用户的下载速度。 Management server after receiving the feedback to inform other users to download the file A, improve download other user's download speed. 这样就使得同一文件在共享控制策略上具有继承性。 This makes the file has the same inheritance on a shared control strategy. 并且在下载用户下载完共享文件后,都可以将该共享文件设置为共享状态,以方便其他的用户进行下载。 After the user has finished downloading and download shared files, shared files are set to the shared state to allow other users to download. 下载用户还可以进一步向管理服务器反馈允许访问的用户标识,这样可以进一步增强文件可控共享的继承性。 Users can also download further feedback allows access to the management server user ID, which can be further enhanced file sharing controllable inheritance.

[0091] 为了完善对共享文件的控制功能,用户还可以进行对共享文件的取消共享操作: 例如共享用户1通过登录服务器认证,登录服务器将用户标识及该用户网络连接信息发送至管理服务器保存后,共享用户1向管理服务器发送取消共享信息,该信息包括:共享文件名、共享用户标识;管理服务器接收到取消共享消息后,将对应的文件取消共享。 After e.g. sharing user 1 through the login server authentication, login server identifies the user and the user network connection information to the management server stored: [0091] In order to improve control of the shared document, the user also can cancel the sharing operation of a shared file shared management server sends the user an unshare, the information comprising: sharing a file name, a shared user identifier; management server after receiving the cancel message sharing, file corresponding to unshared. 在增加了临时密钥后,取消共享的操作可以根据实施例2进行相应的变化,在此不再累述。 After the increase in the temporary key, unshared corresponding change operation can be performed in accordance with Example 2, which will not be described herein.

[0092] 为了完善对共享文件的控制功能,用户还可以进行对共享文件进行统计: [0092] In order to improve control of the shared files, users can share files of statistics:

[0093] 预置同一用户标识使用不同的用户地址登录;用户通过登录服务器认证,登录服务器将用户标识及该用户网络连接信息发送至管理服务器保存后,用户向管理服务器发送统计其共享过的文件请求; Different [0093] user presets using the same user ID address to log in; after user authentication via login server, login server identifies the user and the user network connection information to the management server save the user to send their statistics to share files over to the management server request;

[0094] 管理服务器统计该用户标识共享过的所有可用共享文件信息,并向用户反馈。 [0094] Management server statistics available to share files through shared information that identifies the user, and to user feedback. 该可用共享信息包括了其他用户下载过该文件后的可用连接信息。 The available information includes the sharing of available connections after other users have downloaded the file information.

[0095] 上述的发布共享文件及下载共享文件的方法都是在如图2所示的网络系统架构中实现的。 [0095] The methods published to share files and share files are downloaded in a network system architecture shown in FIG. 2 implemented. 下面叙述一下本发明实施例系统的作用。 The following describes about the role of embodiment of the system of the present invention.

[0096] 登录服务器1,用于存储所有用户标识;接收用户终端2发送的用户标识,验证用户标识是否合法,若是则向管理服务器2发送用户标识及该用户网络连接信息;并将管理服务器的网络连接信息发送给用户终端2。 [0096] login server 1, to store all user identifier; receiving user terminal 2 transmits the user identifier, the user identifier is legitimate authentication, if it is the user management server 2 transmits the user ID and network connection information; and the management server network connection information to the user terminal 2.

[0097] 管理服务器2,用于保存登录服务器1发送的用户标识与该用户网络连接信息;接收用户发送的共享请求消息并保存,该消息包括:共享文件的文件名及能够下载该共享文件的用户标识;接收用户发送的请求下载消息,该消息中携带有请求下载文件的文件名及该用户标识;在接收到请求下载消息后,查找允许该用户下载的信息,查找到后向下载用户发送响应消息,该消息包括:共享文件名、共享该文件的用户标识及网络连接信息; [0097] The management server 2, the user transmits a login server for storing identification information of the connected user network; sharing request message sent by a user and save the message comprising: a file sharing and file name of the shared file can be downloaded a user identifier; receiving a request sent by the user to download the message, the message carries the requested file name to download the file and the user identifier; upon receiving the request to download the message, search information allows the user to download and transmits to the download after the user find response message, the message comprising: a shared file name of the shared user ID and network connection information file;

[0098] 用户终端3,用于向登录服务器1发送用户标识;存储用户标识、选择用户标识,向管理服务器2发送所述的共享请求消息或请求下载消息;接收其他用户终端发送的下载请求,并向其他用户终端传输共享文件。 [0098] The user terminal 3, for sending to the login server a user identifier; store the user identifier, the user identifier selection, the request message or download request message to the management server 2 transmits a shared; receiving a download request sent by another user terminal, transfer to other user terminals to share files.

[0099] 为了提高系统的安全性,增加了临时密钥的功能,因此登录服务器1在上述功能的基础上,进一步用于在接收到用户标识后对应该用户标识生成一个临时密钥;并将该临时密钥发送用户终端3与管理服务器2 ; [0099] In order to improve security of the system, increases the functionality of the temporary key, logon server 1 on the basis of the above functions, it is further configured to generate a temporary key to be user ID after receiving a user identification; and the user terminal transmits temporary key management server 2 and 3;

[0100] 管理服务器2在上述功能的基础上,进一步保存该临时密钥;在接收用户终端发送的临时密钥与所述的共享请求消息后,在确认本地存在与接收到的用户终端发送的临时密钥相同的临时密钥后保存所述的共享请求消息;在向用户终端发送响应消息时进一步包括:共享该文件用户的临时密钥; [0100] management server 2 on the basis of the above functions, to further save the temporary key; after the shared temporary key request message sent by the receiving user terminal, and confirming the presence of the local user terminal to transmit the received after the same temporary key shared temporary key to save the message request; further comprising sending a response message to the user terminal: the temporary key shared document user;

[0101] 用户终端3在上述功能的基础上,本地访问控制策略库进一步用于接收登录服务器发送的临时密钥并保存;在向管理服务器2发送共享请求消息的同时发送该临时密钥; 在向其他用户终端发送下载请求时进一步包括其他用户的临时密钥;接收到其他用户发送的包括该临时密钥的下载请求时,在通过密钥验证后向其他用户终端传输共享文件。 [0101] The user terminal 3 on the basis of the above functions, local access control policy repository is further for receiving a registration server transmits the temporary key and saved; while transmitting the temporary key request message to the management server 2 transmits a shared; in further comprising a temporary key to other users when sending a download request to the other user terminal; receiving a download request including the temporary key from other users, the transmission of the shared files to other users through the terminal key verification.

[0102] 为了使用户能够及时的获取共享文件信息,管理服务器2增加了邀请模块; [0102] In order to enable users to share files get information in a timely manner, the management server 2 adds the invitation module;

[0103] 因此用户终端3,进一步用于在向管理服务器2发送共享请求消息的同时还发送携带有下载用户标识的邀请下载信息;在通过登录服务器1的用户标识验证后,判断是否收到邀请下载信息,该信息包括邀请下载的共享文件名、共享用户网络连接信息、共享用户标识;若没收到则下载用户与管理服务器执行常规信息交互;若收到则与共享用户建立连接下载共享文件或忽略该邀请下载信息后,下载用户再与管理服务器执行常规信息交互; [0103] Thus the user terminal 3, while a further request message to the management server 2 also transmits a shared transmission download user identifier carries an invitation download information; after authentication by user ID login server 1 determines whether the invitation download information, which includes an invitation to download the shared file name, user network connection sharing information, sharing of user identity; if not received the download and user management server performs regular information exchange; if it is received and shared user to establish a connection to download or share files ignore the invitation after downloading information, and then download the user perform regular information exchange with the management server;

[0104] 管理服务器2的邀请模块用于在保存共享请求消息时,判断邀请下载的用户是否在线,向在线的邀请下载用户发送携带有该共享文件名、共享用户网络连接信息、共享用户标识的邀请下载信息;将不在线的邀请下载用户标识、与所述的邀请下载信息对应保存; 并在预置的有效期限内、当邀请下载的用户在线时向邀请下载的用户发送,同时删除保存的该邀请下载信息。 [0104] Invite module management server 2 for saving when sharing request message, it determines whether the invited user online download, the downloaded online users to send invitations carrying the shared file name, user network connection information sharing, shared user identifier invitation download information; invitation will not download online user ID, and downloading the invitation information corresponding stored; and for a preset period of validity, when the invited user sends the invitation to download user when online download, delete the saved the invitation to download information.

[0105] 为了更加完善该文件可控系统的功能,增加了用户取消其共享的某些或全部文件的功能。 [0105] In order to further improve the function of the file system is controllable, increasing the user to cancel some or all of the features of its file sharing.

[0106] 因此用户终端3,进一步用于管理服务器保存登录服务器发送的用户标识与该用户网络连接信息后,向管理服务器发送取消共享消息,该消息包括:共享文件名和共享用户标识; [0106] Thus the user terminal 3, the management server is further configured to save the user's login server sends the user identification information of the network connection, to the management server share cancellation message, the message comprising: sharing the shared file name and a user identifier;

[0107] 管理服务器2的全局访问控制策略库,进一步用于在接收到所述的取消共享消息后,搜索共享文件,并取消该并删除该文件的共享信息。 Global [0107] 2 Management Server database access control policies, further configured to, after receiving the news of the cancellation share, search for shared files, and cancels the sharing of information and delete the file. 也可以不仅将共享用户的这个共享文件条目删除,同时也删除其他因为下载而缺省共享此文件的用户的共享文件条目,即将其他用户的共享副本也取消。 You can not only share the shared file entry for a user to delete, delete the shared files but also other entries because the default share and download the file users, about to share copies of other users also canceled. 这个也是源自共享消息的继承性。 This is the message from the shared inheritance.

[0108] 为了更加完善该文件可控系统的功能,还增加了用户统计其共享文件信息的功能。 [0108] In order to further improve the controllability of the file system functions, users also increased its share statistical information on file functions. 这里的统计就是指查询获得本用户所共享的所有文件的基本信息,包括之前在其他机器上共享的和现在共享的,以及各文件的可用性。 Statistics here refers to the query access to basic information about all files shared by this user, including previously shared on other machines and now share, as well as the availability of each file. 本文提出的是基于用户登录模式的共享, 因此假设用户A曾经在某一台计算机登录且共享过那台计算机的某个文件,当用户A退出之后在其他计算机上登录时,仍然可以查看到以前所共享的文件名等基本信息,但由于用户终端变化,所以用户A自己都无法实际读取到那个曾共享的文件。 This paper is based on a shared user login mode, it is assumed that the user A once logged in and share a file that had computers in one computer, when after the user A Log on another computer, you can still view the previous shared basic information such as file name, but because of changes in the user terminal, the user a himself can not actually read the file was shared. 但是,如果在用户A上一次共享的过程中,有另一个用户B下载了该文件,且该用户B此时在线,那么用户A及其他用户仍然可以访问到上次共享的其他计算机上的文件。 However, if in the course of a share of the user A, B another user downloaded the file, and the user B online at this time, the user A and other users can still access files on other computers to share the last . 这里,B既是服务使用者(下载了文件使用),又是服务提供者(起到了延续文件的可用性和中转的作用)。 Here, B is both service users (download the files), but also a service provider (availability and played a role in the continuation of transit documents). 在响应A的统计的时候,管理服务器仍然认为该文件是可用的,并将其告诉A)。 A response time of the statistics, the management server continues to believe that the document is available, and tell it A).

[0109] 因此用户终端3,进一步用于管理服务器2保存登录服务器发送的用户标识与该用户网络连接信息后,向管理服务器发送统计用户标识共享过文件的请求; [0109] Thus the user terminal 3, for further storage management server 2 transmits the user login server connected to the identification information of the user network, the management server transmits the user identification statistics by requesting the shared file;

[0110] 管理服务器2,进一步用于接收到所述的统计请求后,统计该用户标识共享过的所有可用共享文件信息,并向用户终端1反馈。 After the [0110] management server 2, is further configured to receive a request for the statistics, statistical information of all the available shared files shared over the user identifier, and to feedback the user terminal.

[0111] 综上所述,由于本发明实施例采用了用户标识的登录方法,并且通过全局访问控制策略和用户终端本地访问控制策略的方法,即用户可以自行选择向哪些用户共享文件的权限,使得管理服务器在搜索下载请求信息时只搜索到允许该用户下载的共享文件信息, 实现了由用户控制的文件共享方式。 [0111] As described above, since the embodiment employs a user login identification method of the present invention, methods and strategies and local access and the user terminal access control policy by a global control, i.e., the user can choose which rights to the users to share files, such download management server search request information only allows the user to search for shared files to download information to achieve the control file-sharing by the user. 虽然增加了登录服务器,但是由服务提供商来负担的, 不需要用户自己架设服务器,没有增加用户的硬件或系统开销。 Although the increase in the login server, but by the service provider to affordable, does not require users to set up their own server, there is no increase in the user's hardware or system overhead.

[0112] 并且增加了临时密钥、对临时密钥加密,在用户发布于下载的过程中都需要进行验证,加强了对文件下载与发布的安全性。 [0112] and increased temporary key, the temporary key encryption, the process of downloading users to publish both require authentication, enhanced security for file downloads and released. 并增加了对共享文件的时间控制,在一定程度上能够降低管理服务器存储压力。 And increasing the time control to shared files, to a certain extent, it can reduce the management server storage pressure.

[0113] 在实现了共享、下载文件安全可控的情况下,本发明实施例还提供了邀请机制,使得用户能够及时的获取共享信息;取消共享、统计共享信息的功能进一步完善了文件共享、 下载可控的方法与系统,提高了用户满意度。 [0113] In the case of realizing a shared download files safe and controlled, embodiments of the present invention also provides a mechanism for the invitation, enabling users to share access to timely information; cancel sharing, sharing statistical information to further improve file sharing, Download controllable method and system to improve customer satisfaction.
