具体实施方式 Detailed ways

[0052] 下面结合附图及具体实施例就本发明的技术方案做进一步的说明。 [0052] The embodiment further aspect of the present invention is explained below in conjunction with the accompanying drawings and. 应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。 It should be understood that the specific embodiments described herein are only intended to illustrate the present invention and are not intended to limit the present invention.

[0053] 本发明提出一种云存储方法。 [0053] The present invention proposes a method of cloud storage.

[0054] 参照图1,图1为本发明云存储方法第一实施例的结构示意图。 [0054] Referring to FIG. 1, FIG. 1 is a schematic structural embodiment of the method of the first embodiment of the invention the cloud storage.

[0055] 本发明实施例中提出的一种云存储方法,包括: [0055] A cloud storage method in the embodiment of the present invention is proposed, comprising:

[0056] 步骤S10,接收到数据存储请求后,将要上传的数据分为多组分数据,并为其分配不同的服务器; After [0056] Step S10, the data storage request is received, the data to be uploaded into a multi-component data, and assign different servers;

[0057] 首先将需要上传云服务器的数据分为多组分数据,以便与可用的多组服务器相对应。 [0057] First, the data to be uploaded into the cloud server multicomponent data to correspond to the plurality of sets of available servers. 数据分组规则如下:用户首先设定一个阈值来规定每个分数据的大小,例如lOOkb,然后把需要上传的数据划分为阈值大小的数据包,并为每组分数据编号。 Packet rules are as follows: the user first sets a threshold value to a predetermined size of each sub-data, e.g. lOOkb, then you need to upload the data into a data packet size threshold, and for each set number of data points. 再通过对所使用的若干运营商的服务器进行统一管理,当有数据存储需求的时候,可以对管理中的多组服务器进行选择,从中挑选若干服务器进行存储多个分数据。 Through the unified management of a number of carriers used by the server when the data storage needs, you can choose to manage the multiple sets of servers from which to choose several servers to store multiple data points.

[0058] 由于每组分数据都是不完整的,因此每个服务器的提供商都不能获取用户的隐私。 [0058] Since each sub-data is not complete, and therefore each server provider can not obtain the user's privacy. 因此,即使单个服务器被攻击导致数据泄露,也不会对用户造成损失。 Therefore, even if a single server is attacked result in data leakage, nor will the user losses.

[0059] 步骤S20,将多组分数据上传至相应的服务器,并在上传成功后更新数据表中每组分数据与服务器之间的映射关系。 [0059] step S20, the multi-component data is uploaded to the appropriate server, and updated after a successful upload data table of each fraction and the mapping relationship between the data server.

[0060] 将处理过的多组分数据上传至相应的服务器。 [0060] The treated multicomponent data uploaded to the appropriate server. 上传过程后更新数据表中每组分数据与服务器之间的映射关系,同时将每一份分数据保存的路径保存在虚拟目录下。 Update data in the table per component mapping relationship between the data and the server after the upload process, and save every minute of data stored in a virtual directory path.

[0061] 本发明实施例中提出的云存储方法,在上传数据时,通过将完整的用户数据拆分为多个部分,并将多个分数据分别存储在不同的服务提供商,这样可以保证单个服务提供商无法获取用户的隐私数据,即使服务器被攻击时,也不会导致用户信息被泄露。 [0061] Cloud storage method proposed in the embodiment of the present invention, when uploading data, by the complete user data is split into a plurality of portions, and the divided data are stored in the plurality of different service providers, you can guarantee single service provider can not obtain the user's private data, even when the server is attacked, it will not result in the user information was leaked. 此外,通过对多个云存储服务提供商提供的云存储资源的整合,使用户可用的存储空间能够得以便捷的动态扩展。 In addition, through the integration of cloud storage resources to multiple cloud storage service providers, allowing users to available storage space can be easy dynamic expansion.

[0062] 参照图2,图2为本发明云存储方法第二实施例的结构示意图。 [0062] Referring to FIG. 2, FIG. 2 is a schematic structural diagram of a second embodiment of the method of the invention cloud storage.

[0063] 本发明第二实施例提出的一种云存储方法,在上一实施例的基础上,在执行步骤SlO之前还包括: [0063] A second embodiment of the cloud storage method of the present invention provides, in one embodiment based on the embodiment, before performing step SlO further comprising:

[0064] 步骤S30,判断服务器是否为合法用户; [0064] step S30, it is determined whether the server is a legitimate user;

[0065] 若是,则执行步骤S31 ;若否,则回到步骤S30。 [0065] If yes, go to step S31; if not, the process returns to step S30.

[0066] 步骤S31,将服务器的信息保存到数据表。 [0066] step S31, the server saves the information to the data table.

[0067] 执行步骤S31后,进入步骤S10。 [0067] After step S31, it proceeds to step S10.

[0068] 整个过程实际就是为一个初始化的过程。 [0068] The whole process is actually a initialization process. 首先对服务器进行授权认证,判断服务器是否为合法用户,当判断服务器为合法用户时,保存服务器的信息并更新数据表。 First, the server authorization and authentication, the server determines whether the user is legitimate, when it is judged as a legitimate user server, save the information server and update the data table. 如果是合法用户,就在用户的数据表中保存云服务器的信息,包括性能、容量、带宽、费用等信息,当服务器更新时,服务器列表也随之更新。 If you are a legitimate user, the user's data is saved in the cloud server table information, including information on performance, capacity, bandwidth, cost, etc., when the server update the server list is also updated. 当判断服务器不为合法用户时,则继续对下一个运营商服务器进行授权认证,直到将所有的服务器都认证完毕。 When the server is not judged as a legitimate user authorization and authentication continues to the next operator server until all servers authentication is completed. 如果是第一次使用,还需要逐个输入已有运营商的账号和密码进行适配。 If this is the first time, also you need to enter an existing one by the operator's account and password adaptation.

[0069] 通过初始化过程对服务器进行授权认证,进一步增强了该云存储方法的安全性。 [0069] authorization authentication server through the initialization process, further enhancing the security of the cloud storage method.

[0070] 参照图3,图3为本发明云存储方法第三实施例的结构示意图。 [0070] Referring to FIG 3, FIG. 3 is a schematic structural diagram of a third embodiment of the method of the invention cloud storage.

[0071] 本发明第三实施例提出的一种云存储方法,在上一实施例的基础上,在执行步骤SlO和步骤S20之间还包括: [0071] A cloud storage method of the third embodiment of the present invention set forth in the previous embodiment based on the embodiment, between step S20 and SlO step further comprises:

[0072] 步骤S40,判断分数据是否需要加密;若是,则执行步骤S41 ;若否,则执行步骤S20。 [0072] step S40, the data points is determined whether encryption is required; if yes, step S41 is performed; if not, proceed to step S20. 执行步骤S41后,进入步骤S20。 After executing step S41, the process proceeds to step S20.

[0073] 在数据表中对上传加密的分数据增加标识。 [0073] increase in the data table identifying the encrypted sub-data uploaded. 加密方法可以自由设计,可以在装置内嵌一个加密芯片。 Can be freely designed encryption method, encryption chip can be embedded in a device. 本实施例提出一种加密方法:随机选取编号为m的分数据作为密钥,将此分数据与其他所有分数据与之进行异或操作后,再进行上传,而编号m分数据不做操作。 The present embodiment proposes an encryption method: after randomly selected number m of data points as a key, this data points with data points with all other XOR operation, and then upload the data division number m is not operating . 相应的解密方法为:所有加密过的分数据与编号为m分数据再次异或操作,从而解码出原分数据。 Corresponding decryption method: All sub-data encrypted with the number m of data points XOR operation again, thereby decoding the original data points.

[0074] 此外,对于分数据的处理方面,不单单仅限于加密操作。 [0074] Further, for the processing of data points, not just limited to encryption. 可以对分数据引入编码方案,比如通过对各个分数据加入冗余信息和校验信息,来增加数据存储的健壮性。 Can be introduced to the sub-data encoding scheme, such as the data on the respective sub-redundant information and parity information is added, to increase the robustness of the stored data.

[0075] 根据装置的性能确定分数据是否加密。 [0075] The sub-data is encrypted according to the determined device performance. 如果云存储装置的性能足够支持加密的操作,可以选择分数据进行加密后再传输分数据,这样对用户信息能够进行进一步保护。 If the performance is sufficient cloud storage device supports encryption operation can be selected division points encrypts data before transmitting the data, so that the user information can be further protected. 如果选择不加密,则直接传输分数据,这样可以减小装置的负载,降低能耗。 If you choose not encrypted, the direct transmission of data points, so that the load device can be reduced, reducing power consumption. 当然,为了增强安全性,在装置性能足够支持的情况下,最好选择加密后传输。 Of course, in order to enhance security, in the case where the device performance a sufficient support, the best choice for the encrypted transmission. 至于选择何种加密方法,可以自由进行扩展。 As for what encryption method you choose, you can expand freely.

[0076] 通过根据不同装置的性能来对上传到服务器中的分数据自由地选择是否进行加密,使云存储方法更加灵活,同时可以引入不同的分数据处理方法,而不单单仅限于加密操作,使分数据的储存更加安全。 [0076] by sub-data uploaded to the server is free to choose whether to encrypt the different properties of the device according to the cloud storage method is more flexible, and can introduce different sub-data processing method, not just limited to encryption, the stored data more secure points.

[0077] 本发明提出一种云存储装置。 [0077] The present invention proposes a cloud storage device.

[0078] 参照图4,图4为本发明云存储装置第一实施例的结构示意图。 [0078] Referring to FIG 4, which illustrates a schematic structural diagram of a first embodiment of the invention cloud storage.

[0079] 本实施例中,云存储装置包括: [0079] In this embodiment, the cloud storage apparatus comprising:

[0080] 数据分组模块10,用于将要上传的数据分为多组分数据,并根据虚拟目录选择多组相应的服务器与之对应; [0080] Data packet module 10 for data to be uploaded into the multi-component data, and select a plurality of sets corresponding to the virtual server corresponding directory;
