具体实施方式Detailed ways

本发明提供了一种便携式云存储方法，该方法利用具有一定存储容量的便携式云存储设备作为磁盘，为用户提供高速快捷的海量虚拟存储空间，而远程的云存储服务器则为用户提供更高效更可靠的海量存储平台。用户所有数据全部保存于在便携式云存储设备和远端的云存储服务器中，不本地宿主机上存储任何数据，使用过程中也不会在本地产生任何临时文件。存储于便携式云存储设备的数据全部经过加密，必须首先验证用户身份才能正常读写数据，更增加了用户进行数据读写过程中的安全性。The invention provides a portable cloud storage method, which uses a portable cloud storage device with a certain storage capacity as a disk to provide users with high-speed and fast massive virtual storage space, while a remote cloud storage server provides users with more efficient and more Reliable mass storage platform. All user data is stored in portable cloud storage devices and remote cloud storage servers. No data is stored on the local host, and no temporary files are generated locally during use. The data stored in the portable cloud storage device is all encrypted, and the user's identity must be verified first to read and write the data normally, which increases the security of the user in the process of reading and writing data.

本发明的方法如图1所示，主要包括以下步骤：Method of the present invention as shown in Figure 1, mainly comprises the following steps:

1)将便携式云存储设备连接到宿主机上，通过网络与远程云存储服务器保持连接；1) Connect the portable cloud storage device to the host machine, and keep connected with the remote cloud storage server through the network;

2)打开便携式云存储设备中的客户端，输入用户名和密码，执行登录认证操作；2) Open the client in the portable cloud storage device, enter the user name and password, and perform the login authentication operation;

3)认证通过以后，该便携式存储装置利用驱动程序模拟了一个虚拟磁盘供用户存储数据，并将用户待读写的数据下载/上传至远程云存储服务器中；3) After passing the authentication, the portable storage device uses the driver to simulate a virtual disk for the user to store data, and downloads/uploads the data to be read and written by the user to the remote cloud storage server;

4)操作完成以后，用户退出系统，并从宿主机上取下便携式云存储设备。4) After the operation is completed, the user exits the system and removes the portable cloud storage device from the host machine.

其中，该便携式云存储设备可以是U盘或者移动硬盘等可以和计算机连接的便携式存储介质。另外，用户在对本地的数据进行写入操作时，该便携式存储装置在后台将用户写入的数据及时同步到云存储服务器中，如果因网络故障或用户不在线未能同步，则会对该部分数据进行未同步标记，则在网络恢复之后或者用户下次登录网络时，便携式存储装置会将具有未同步标记的数据上传至云存储服务器后，并取消未同步标记。用户在读取本地未存在的数据时(即本地仅为壳文件，壳文件的大小为0KB)，需要将数据从云存储服务器下载至本地，便携式存储装置会先从云存储服务器找到相关的数据，并判断便携式云存储设备是否有足够的空间下载该数据，如果有，则下载数据，如果没有，则需先启动磁盘清理流程，进行磁盘清理，直至有足够的存储空间后，才下载数据，并且在下载过程中，便携式存储装置随时监控已经使用的存储空间是否到达设定的清理阈值，如果到达，则启动磁盘清理流程。Wherein, the portable cloud storage device may be a portable storage medium that can be connected to a computer, such as a U disk or a mobile hard disk. In addition, when the user writes local data, the portable storage device will synchronize the data written by the user to the cloud storage server in time in the background. If the synchronization fails due to network failure or the user is not online, the If part of the data is marked as out of synchronization, after the network is restored or the user logs in to the network next time, the portable storage device will upload the data with the mark of out of sync to the cloud storage server, and cancel the mark of out of sync. When the user reads data that does not exist locally (that is, the local is only a shell file, and the size of the shell file is 0KB), the user needs to download the data from the cloud storage server to the local, and the portable storage device will first find the relevant data from the cloud storage server , and judge whether the portable cloud storage device has enough space to download the data, if so, download the data, if not, start the disk cleaning process first, perform disk cleaning, and download the data until there is enough storage space, And during the downloading process, the portable storage device monitors at any time whether the used storage space reaches the set cleaning threshold, and if so, starts the disk cleaning process.

用户在使用本发明的便携式存储装置在线存储数据时，由于便携式云存储设备的本地容量有限，便携式云存储设备的本地存储容量易出现存储空间不足的情况，在这种情况下，本 发明提供了一种磁盘清理方法，及时将使用频率低、占据空间大的数据同步到远程云存储服务器中去，这里的磁盘清理算法将使用LRU(Least Recently Used)算法，即最近最少使用页面置换算法，是为虚拟页式存储管理服务的。在内存有限的情况下，扩展一部分外存作为虚拟内存，真正的内存只存储当前运行时所用得到信息，当文件存放在便携式云存储设备中时，在没有超过指定剩余空间时，不会发生磁盘清理操作，当发现超过指定剩余空间，就会启动此空间清理办法，将便携式云存储设备里面不经常使用的文件(例如大文件或.ISO、.BAK等)做磁盘清理操作，上传至云存储服务器中，然后本地变成壳文件(文件大小为0KB)，该方法的具体流程如图2所示：When the user uses the portable storage device of the present invention to store data online, due to the limited local capacity of the portable cloud storage device, the local storage capacity of the portable cloud storage device is prone to insufficient storage space. In this case, the present invention provides A disk cleaning method, which synchronizes the data with low frequency of use and large space to the remote cloud storage server in time. The disk cleaning algorithm here will use the LRU (Least Recently Used) algorithm, which is the least recently used page replacement algorithm. Serving for virtual paging storage management. In the case of limited memory, expand a part of the external memory as virtual memory. The real memory only stores the information used during the current operation. When the file is stored in the portable cloud storage device, if the specified remaining space is not exceeded, no disk will be generated. Cleanup operation, when it is found that the specified remaining space is exceeded, this space cleanup method will be activated, and files that are not frequently used in the portable cloud storage device (such as large files or .ISO, .BAK, etc.) will be cleaned up and uploaded to the cloud storage In the server, then the local becomes a shell file (the file size is 0KB), and the specific process of the method is as shown in Figure 2:

21)判断用户所打开的文件是否在队列中，其中，该队列为保存最近打开的文件名队列，按照使用先后顺序排序的先进先出(FIFO)队列(最不常使用的放在头部，最常使用放在尾部)；21) Determine whether the file opened by the user is in the queue, wherein the queue is to save the recently opened file name queue, and the first-in-first-out (FIFO) queue sorted according to the order of use (the least frequently used one is placed on the head, Most commonly used at the end);

22)如果在队列中，从队列中删除，放在队列尾部；22) If it is in the queue, delete it from the queue and put it at the end of the queue;

23)如果不在队列中，直接放入队列尾部；23) If not in the queue, put it directly into the tail of the queue;

24)判断现在所使用的总存储容量是否到达或超过所设定的开始清理阈值(例如设定清理阈值为便携式云存储设备的存储总容量的80％)；24) Judging whether the total storage capacity used now reaches or exceeds the set start cleaning threshold (for example, setting the cleaning threshold to be 80% of the total storage capacity of the portable cloud storage device);

25)没有到达或者超过所设定的阈值，返回结束；25) If it does not reach or exceed the set threshold, return to end;

26)如果到达或者超过所设定的阈值，从队列头部开始清理缓存，采用分批方式(比如总数的1％)一批一批删除队列头部，直至当前使用磁盘的使用空间小于使用结束清理阈值(例如设定清理阈值为便携式云存储设备的存储总容量的60％)，其中，这里选取60％小于上述设定的80％是为了清理方便，减少清理的次数，当然，这个百分比数字不是固定的，可以根据用户使用的需要自行设定。26) If it reaches or exceeds the set threshold, clear the cache from the head of the queue, and delete the head of the queue batch by batch in batches (for example, 1% of the total), until the currently used disk space is less than the end of use Cleanup threshold (for example, set the cleanup threshold to be 60% of the total storage capacity of the portable cloud storage device), wherein, choosing 60% here to be less than 80% of the above-mentioned setting is to facilitate cleaning and reduce the number of times of cleaning. Of course, this percentage figure It is not fixed and can be set according to the needs of users.

27)返回结束。27) Return to end.

本申请的另一实施例如图2a所示，包括：Another embodiment of the present application is shown in Figure 2a, including:

2’1)判断用户所打开的文件是否在队列中，其中，该队列为保存最近打开的文件名队列，按照使用频率排序的有序队列；2'1) Determine whether the file opened by the user is in the queue, wherein the queue is an ordered queue for saving the recently opened file name queue and sorted according to the frequency of use;

2’2)如果在队列中，在用户使用次数的记录上增加一次计数，然后从队列中删除，根据该文件所有使用次数，找到在队列中的位置，如果存在使用次数相同的记录时，放在所有相同次数记录的后面，重新入列；2'2) If it is in the queue, add a count to the record of the user's usage times, and then delete it from the queue. According to all the usage times of the file, find the position in the queue. If there are records with the same usage times, put After all records with the same number of times, re-enqueue;

2’3)如果不在队列中，对所述文件使用次数设置为1，并判断现在所使用的总存储容量是否到达或超过所设定的清理阈值(例如设定清理阈值为便携式云存储设备的存储总容量的80％)；2'3) If not in the queue, set the number of times the file is used to 1, and judge whether the total storage capacity used now reaches or exceeds the set cleanup threshold (for example, set the cleanup threshold to be that of the portable cloud storage device 80% of the total storage capacity);

2’4)没有到达或者超过所设定的阈值，入列；2'4) If it does not reach or exceed the set threshold, it will be included;

2’5)如果到达或者超过所设定的阈值，则根据预设的规则，找到满足条件的文件，逐一清理，释放至足够的磁盘空间后，然后将当前文件入列，其中，所述预设的规则可以是根据文件使用频率的高低或者是文件的优先级高低等条件。2'5) If it reaches or exceeds the set threshold, then according to the preset rules, find the files that meet the conditions, clean them one by one, release enough disk space, and then list the current files, wherein the preset The set rule may be based on conditions such as the frequency of file usage or the priority of the file.

其中，在上述步骤2’5)的清理磁盘空间的时候，还可以采用磁盘自动清理的方式，如图3a所示，具体步骤如下：Wherein, when clearing up the disk space in above-mentioned steps 2'5), the mode of automatic disk cleaning can also be adopted, as shown in Figure 3a, the specific steps are as follows:

31)从预设的规则中选择筛选文件的条件；例如，所述预设的条件可以是文件的使用频率、文件类型的优先级，文件的大小几个条件中的一个或多个组合；31) Select a condition for filtering files from preset rules; for example, the preset condition can be one or more combinations of the frequency of use of the file, the priority of the file type, and the size of the file;

32)根据选定的条件设置一第一阈值，32) setting a first threshold according to the selected condition,

33)清理满足小于所述阈值的所有文件；33) Clean up all files that meet the threshold value smaller than the threshold;

34)判断清理完成后当前磁盘的使用空间是否小于清理阈值，如果是，返回结束，如果不是，则返回执行步骤31)，直至当前使用磁盘的使用空间小于使用清理阈值。34) After judging whether the used space of the current disk is less than the cleaning threshold after the cleaning is completed, if yes, return to end, if not, then return to step 31) until the current used space of the disk is less than the cleaning threshold.

用户在使用的时候，可以根据自身的需求增加筛选条件，也可以根据已有的筛选条件进行安排，例如，仅使用文件使用频率这一条作为筛选条件，那么，上述磁盘自动清理的流程如图3a.1所示：When users are using it, they can add filter conditions according to their own needs, or arrange according to existing filter conditions. For example, only use the frequency of file usage as a filter condition. Then, the above-mentioned automatic disk cleaning process is shown in Figure 3a .1 shows:

311)设置一第一文件使用频率阈值；311) Setting a first file usage frequency threshold;

312)清理满足小于所述阈值的所有文件；312) Clean up all files meeting the threshold value smaller than the threshold;

313)判断清理完成后当前磁盘的使用空间是否小于清理阈值，如果是，返回结束，如果不是，执行下一步；313) After judging whether the used space of the current disk is less than the cleaning threshold after the cleaning is completed, if yes, return to the end, if not, perform the next step;

314)设定一高于上述第一使用频率阈值的第二使用频率阈值，返回执行步骤313)，直至当前使用磁盘的使用空间小于使用清理阈值。314) Set a second usage frequency threshold higher than the above-mentioned first usage frequency threshold, and return to step 313), until the currently used disk space is smaller than the usage cleanup threshold.

这里的阈值可以是由用户自行设定或由厂家在出场时做默认设定。The threshold here can be set by the user or by default when the manufacturer leaves the factory.

根据这种方式，如果用户选择根据现有的筛选条件进行安排，选择多个筛选条件进行清理，例如，用户选择根据文件使用频率，文件类型的优先级以及文件大小三个条件依次来进行磁盘空间清理，上述磁盘空间清理流程则如图3a.2所示：According to this method, if the user chooses to arrange according to the existing filter conditions, select multiple filter conditions to clean up, for example, the user chooses to perform disk space according to the three conditions of file usage frequency, file type priority and file size. Cleaning, the above disk space cleaning process is shown in Figure 3a.2:

321)设置一第一文件频率阈值；321) Setting a first file frequency threshold;

322)清理满足小于该第一阈值的所有文件；322) Clean up all files meeting the first threshold;

323)判断清理上述文件后使用空间是否小于清理阈值，如果是，返回结束，如果不是，则执行下一步；323) Judging whether the space used after cleaning the above-mentioned files is less than the cleaning threshold, if yes, return to the end, if not, then perform the next step;

324)进一步根据文件优先级进行筛选，设置一第一文件优先级阈值；324) further filter according to the file priority, and set a first file priority threshold;

325)清理满足小于该第一文件优先级阈值的所有文件；325) Clean up all files that meet the priority threshold less than the first file;

上述实施方式给用户提供了多种选择条件，用户可以根据自己的实际使用情况灵活安排，另外，有些用户在使用磁盘空间清理的方式时，希望被删除的数据尽可能的少，那么，在具体的实施过程中，可以将上述磁盘空间清理的方式步骤33)和34)步骤顺序相互交换即可实现上述目的，如图3b所示，上述流程变为：The above implementation mode provides users with a variety of selection conditions, and users can make flexible arrangements according to their actual usage conditions. In addition, some users hope to delete as little data as possible when using the disk space cleaning method. In the implementation process, the above-mentioned steps 33) and 34) of the disk space cleaning method can be exchanged with each other to achieve the above-mentioned purpose. As shown in Figure 3b, the above-mentioned process becomes:

3’1)从预设的规则中选择筛选文件的条件；例如，所述预设的条件可以是文件的使用频率、文件类型的优先级，文件的大小几个条件中的一个或多个组合；3'1) Select the conditions for filtering files from the preset rules; for example, the preset conditions can be one or more combinations of the frequency of use of the file, the priority of the file type, and the size of the file ;

3’2)根据选定的条件设置一第一阈值；3'2) setting a first threshold according to the selected condition;

3’3)判断清理完成后当前磁盘的使用空间是否小于清理阈值，如果是，执行3’1)，如果不是，执行下一步，直至所有筛选条件都选择过且当前使用磁盘的使用空间小于使用清理阈值时，返回步骤3’5)；3'3) Determine whether the current disk usage space is less than the cleaning threshold after the cleaning is completed, if yes, execute 3'1), if not, execute the next step until all filter conditions are selected and the current disk usage space is less than the usage When cleaning the threshold, return to step 3'5);

3’4)清理满足小于所述阈值的所有文件，返回步骤3’2)；3'4) clean up and meet all files less than the threshold, return to step 3'2);

3’5)返回结束。3'5) Return to end.

用户在使用的时候，可以根据自身的需求增加筛选条件，也可以根据已有的筛选条件进行安排，例如，仅使用文件使用频率这一条作为筛选条件，那么，上述磁盘自动清理的流程如图3b.1所示：When users are using it, they can add filter conditions according to their own needs, or arrange according to existing filter conditions. For example, only use the frequency of file usage as a filter condition. Then, the above-mentioned automatic disk cleaning process is shown in Figure 3b .1 shows:

3’11)设置一第一文件使用频率阈值；3'11) setting a first file usage frequency threshold;

3’12)判断清理完成后当前磁盘的使用空间是否小于清理阈值，如果是，执行下一步，如果不是，执行3’14)；3'12) After judging whether the used space of the current disk is less than the cleaning threshold after the cleaning is completed, if yes, perform the next step, if not, perform 3'14);

3’13)设定一低于上述第一使用频率阈值的第二使用频率阈值，返回执行步骤3’12)；3'13) set a second frequency of use threshold lower than the first frequency of use above-mentioned threshold, return to perform step 3'12);

3’14)清理满足小于所述阈值的所有文件；3'14) clean up all files that meet the threshold value smaller than;

3’15)设定一高于上述第一使用频率阈值的第三使用频率阈值；3'15) setting a third usage frequency threshold higher than the first usage frequency threshold;

3’16)判断清理完成以后当前磁盘的使用空间是否小于清理阈值，如果是，返回结束，如果否，继续清理满足小于所述第三使用频率阈值的所有文件后，设定一高于第三使用频率阈值的第四使用频率阈值，重复执行至当前磁盘使用空间小于清理阈值为止。3'16) After judging whether the used space of the current disk is less than the cleaning threshold after the cleaning is completed, if yes, return to the end, if not, after continuing to clean up all files that meet the threshold of less than the third usage frequency, set one higher than the third The fourth usage frequency threshold of the usage frequency threshold is repeatedly executed until the current disk usage space is smaller than the cleaning threshold.

这里的阈值可以是由用户自行设定或由厂家在出场时做默认设定，例如，厂家可以设置以每档固定百分比的幅度递增的一组阈值，供用户从低到高选择使用。这样可以在条件允许的范围内删除最少的用户数据。The threshold here can be set by the user or by default when the manufacturer leaves the factory. For example, the manufacturer can set a set of thresholds that increase by a fixed percentage for each level for the user to choose from low to high. This removes as little user data as conditions allow.

如果用户选择多种筛选条件进行磁盘清理，例如，用户选择根据文件使用频率，文件类型的优先级以及文件大小三个条件依次来进行磁盘空间清理，上述磁盘空间清理流程则如图3b.2所示：If the user selects multiple filter conditions for disk cleanup, for example, the user chooses to perform disk space cleanup according to the three conditions of file usage frequency, file type priority, and file size in sequence, the above disk space cleanup process is shown in Figure 3b.2 Show:

3’21)设置一第一文件频率阈值；3'21) setting a first file frequency threshold;

3’22)判断清理上述文件后使用空间是否小于清理阈值，如果是，执行3’34)，如果不是，则执行下一步；3'22) Judging whether the space used after cleaning the above files is less than the cleaning threshold, if yes, execute 3'34), if not, then execute the next step;

3’23)清理满足小于该第一阈值的所有文件，返回步骤3’22)；3'23) clean up and meet all files less than the first threshold, return to step 3'22);

3’24)进一步根据文件优先级进行筛选，设置一第一文件优先级阈值；3'24) further filter according to the file priority, and set a first file priority threshold;

3’25)判断清理上述文件后使用空间是否小于清理阈值，如果是，执行步骤3’27)，如果不是，则执行下一步；3'25) judging whether the space used after cleaning up the above-mentioned files is less than the cleaning threshold, if yes, execute step 3'27), if not, then execute the next step;

3’26)清理满足小于该第一文件优先级阈值的所有文件，返回步骤3’25)；3'26) clean up and meet all files less than the first file priority threshold, return to step 3'25);

3’27)进一步根据文件大小进行筛选，设置一第一文件大小阈值，3'27) further filter according to file size, set a first file size threshold,

3’28)判断清理上述文件后使用空间是否小于清理阈值，如果是，执行下一步，如果不是，则进一步设置一大于上述第一文件大小阈值的第二文件大小阈值，继续执行步骤3’28)，直至使用空间小于清理阈值为止；3'28) Determine whether the space used after cleaning the above-mentioned files is less than the cleaning threshold, if yes, execute the next step, if not, further set a second file size threshold greater than the first file size threshold, and continue to execute step 3'28 ) until the used space is less than the cleaning threshold;

3’29)清理满足大于该第一文件大小阈值的所有文件；3'29) clean up all files that meet the first file size threshold;

3’30)返回结束。3'30) Return to end.

以上的实施例仅做为具体实例说明，在实际使用过程中，用户可以根据自己的实际需求设置筛选条件，在此不再多做赘述。从上述描述我们可以看出，在磁盘自动清理的方式过程中，用户可以根据自身的需求自行设定筛选条件，也可以不做处理，根据系统默认的设置自行进行筛选。筛选的条件组合多种多样，灵活方便。The above embodiments are only used as specific examples for illustration. During actual use, users can set filter conditions according to their actual needs, and details will not be repeated here. From the above description, we can see that in the process of automatic disk cleaning, users can set filter conditions according to their own needs, or they can not do any processing and filter by themselves according to the default settings of the system. There are various combinations of screening conditions, which are flexible and convenient.

在上述技术方案中，如果用户在使用时是首次登陆，还需要进行注册认证过程，该注册过程主要是通过云存储服务器利用保存在该便携式云存储设备中的硬件码生成认证证书后并下发给便携式云存储设备，供该便携式云存储设备以后登录认证时作为认证依据，其中所述硬件码是该便携式云存储设备唯一的身份标识，是由硬件厂商出厂时即刻录在该便携式云存储设备中，不可随意改写。用户的具体注册流程如图4所示，具体包括：In the above technical solution, if the user is logging in for the first time, the registration and authentication process needs to be performed. The registration process is mainly through the cloud storage server using the hardware code stored in the portable cloud storage device to generate the authentication certificate and issue the certificate. For a portable cloud storage device, it will be used as an authentication basis for the portable cloud storage device to log in and authenticate in the future, wherein the hardware code is the unique identity of the portable cloud storage device, which is recorded on the portable cloud storage device by the hardware manufacturer when it leaves the factory. , cannot be rewritten at will. The specific registration process of the user is shown in Figure 4, including:

41)首先执行网络状态检查，检查本地与云存储服务器的网络连通性，确认用户在线；41) First perform a network status check, check the network connectivity between the local and the cloud storage server, and confirm that the user is online;

42)用户在注册界面输入用户名、密码以及邮箱等信息，上述信息以及硬件码被发送到云 存储服务器进行注册认证；42) The user enters user name, password, email and other information on the registration interface, and the above information and hardware code are sent to the cloud storage server for registration and authentication;

43)云存储服务器对用户的硬件码进行验证，如果认证通过，则创建证书，如果创建证书成功，便携式云存储设备对该证书进行备份，并显示注册完成，如果创建证书不成功，则执行下一步；其中，所述证书包括用户名，密码、邮箱信息、身份证以及便携式存储装置的硬件码等信息。43) The cloud storage server verifies the user's hardware code. If the authentication passes, a certificate is created. If the certificate is successfully created, the portable cloud storage device backs up the certificate and displays that the registration is complete. If the certificate creation is unsuccessful, execute the following One step; wherein, the certificate includes information such as user name, password, mailbox information, ID card and hardware code of the portable storage device.

44)返回注册失败的信息。44) Return the information of registration failure.

用户在创建证书成功，完成注册后，再次登录的时候执行的是登录流程。同时，如果用户本地证书正常时也需执行登陆操作，如果用户出现密码忘记或者便携式云存储设备丢失或损坏后再次恢复证书成功时也会进行登录操作。上述三种情况的登录的具体过程如图5所示，包括：After the user successfully creates the certificate and completes the registration, the login process is executed when the user logs in again. At the same time, if the user's local certificate is normal, the login operation is also required. If the user forgets the password or the portable cloud storage device is lost or damaged, the login operation will also be performed when the certificate is successfully restored again. The specific process of login in the above three situations is shown in Figure 5, including:

51)显示登录界面，用户输入用户名和密码进行登录；51) Display the login interface, and the user enters the user name and password to log in;

52)便携式云存储设备进行对用户的身份的合法性进行确认，如果合法，则进一步读取硬件码，如果不合法，则执行步骤55)；52) The portable cloud storage device confirms the legality of the user's identity, if it is legal, then further read the hardware code, if it is not legal, then perform step 55);

53)判断用户密码与本地保存的密码是否一致，如果一致，则通过验证，可以正常登录；如果不一致，则表示本地验证不通过，进一步进行云存储服务器验证；53) Judging whether the user password is consistent with the password stored locally, if it is consistent, it will pass the verification and log in normally; if it is inconsistent, it means that the local verification is not passed, and further verification of the cloud storage server is performed;

54)如果云存储服务器返回信息确认用户密码与其证书中的密码一致，则并保存修改本地证书的密码，同时返回用户通过验证，可以正常登录；如果云存储服务器返回信息确认用户密码与其证书的密码不一致，则执行下一步；54) If the cloud storage server returns information confirming that the user password is consistent with the password in the certificate, save and modify the password of the local certificate, and at the same time return that the user has passed the verification and can log in normally; if the cloud storage server returns information confirming that the user password and the password of the certificate If not, proceed to the next step;

55)返回验证失败信息。55) Return verification failure information.

用户在成功登录以后，该便携式存储装置会提供自身模拟的虚拟磁盘作为用户的磁盘空间，并同时将用户待读写的数据下载/上传至远程云存储服务器中，操作完成以后，用户退出系统，并可以从宿主机上取下便携式云存储设备。所有以上的过程在只在便携式存储介质和远程云存储服务器上有数据的上载/下传，而在宿主机上不会有任何用户的数据，在使用过程中也不会生成临时文件，所以，对用户来说，无论在何处何地使用任何宿主机都具有很高的安全性，不存在因宿主机导致用户数据泄密的风险，提高了用户使用的安全性体验。同时，也使用户在不同的主机环境下都能无缝的使用应用程序，实现操作环境的统一。After the user successfully logs in, the portable storage device will provide its own simulated virtual disk as the user's disk space, and at the same time download/upload the data to be read and written by the user to the remote cloud storage server. After the operation is completed, the user exits the system. And the portable cloud storage device can be removed from the host computer. All the above processes only upload/download data on portable storage media and remote cloud storage servers, and there will be no user data on the host machine, and no temporary files will be generated during use, so, For users, no matter where they use any host machine, it has high security, and there is no risk of user data leakage caused by the host machine, which improves the security experience of users. At the same time, it also enables users to seamlessly use applications in different host environments, achieving a unified operating environment.

用户在存取数据的过程中，该便携式云存储设备与远程云存储服务器通过基于TCP/IP的自定义网络通讯协议交互。During the user's access to data, the portable cloud storage device interacts with the remote cloud storage server through a custom network communication protocol based on TCP/IP.

用户在使用过程中，可能会存在原有便携式云存储设备丢失(遗失盘)，使用新的便携式云存储设备(恢复盘)进行数据恢复，即将遗失盘的内容恢复到恢复盘中，这时需要用户对遗失盘挂失后才能使用恢复流程，挂失时需提供用户唯一的身份信息给管理员，由管理员进 行统一操作。另外，由于用户本地的证书文件或者加密文件被破坏，需要对程序进行出厂恢复，将原有的用户数据恢复回原有的便携式云存储设备中。这时候，需要执行恢复流程，恢复流程具体包括证书恢复和数据恢复两部分，证书恢复流程是用户通过有效信息验证，将备份证书中的信息导入到真正的证书文件中，以便程序可以正常使用证书文件。数据恢复流程在证书恢复过程执行完成以后，下次登录时进行，从服务器中读取文件信息列表，并进行真实的文件恢复过程。证书恢复流程如图6所示，具体包括：During use, the user may lose the original portable cloud storage device (lost disk), and use a new portable cloud storage device (recovery disk) for data recovery, that is, to restore the contents of the lost disk to the recovery disk. The user can only use the recovery process after reporting the loss of the lost disk. When reporting the loss, the user must provide the user's unique identity information to the administrator, and the administrator will perform unified operations. In addition, because the user's local certificate file or encrypted file is damaged, it is necessary to restore the program to the factory, and restore the original user data to the original portable cloud storage device. At this time, a recovery process needs to be performed. The recovery process specifically includes two parts: certificate recovery and data recovery. The certificate recovery process is that the user passes the valid information verification and imports the information in the backup certificate into the real certificate file so that the program can use the certificate normally. document. The data recovery process is performed at the next login after the certificate recovery process is completed, and the file information list is read from the server, and the real file recovery process is performed. The certificate recovery process is shown in Figure 6, which specifically includes:

61)用户进入证书恢复界面，输入用户名、密码，身份证以及邮箱；61) The user enters the certificate recovery interface, and enters the user name, password, ID card and email address;

62)将用户输入的密码，邮箱及身份证发送到服务器进行验证，如果合法，则读取备份证书，如果不合法，转至步骤65)；62) The password input by the user, email address and ID card are sent to the server for verification, if legal, then read the backup certificate, if not legal, go to step 65);

63)根据从备份证书中读取的信息对云盘进行认证；如果失败，转至步骤65)；63) authenticate the cloud disk according to the information read from the backup certificate; if it fails, go to step 65);

64)证书恢复成功之后，设置恢复标志，如果出现错误，则转至步骤65)；64) After the certificate is restored successfully, the restoration flag is set, and if an error occurs, then go to step 65);

65)返回出错信息。65) Return an error message.

在证书恢复流程中，设置恢复标志之后，则会进行数据恢复流程，具体如图7所示，包括：In the certificate recovery process, after the recovery flag is set, the data recovery process will be carried out, as shown in Figure 7, including:

71)恢复标志是否置位，如果置位，读取服务器的文件列表；如果未置位，则返回结束；71) Whether the recovery flag is set, if set, read the file list of the server; if not set, then return to end;

72)读取文件列表中文件的类型，若为壳文件进入步骤73，若为已同步文件进入步骤74)；72) read the type of file in the file list, if it is a shell file and enterstep 73, if it is a synchronized file and enter step 74);

73)创建壳文件图标，成功后删除文件列表中的对应项，进入步骤75；73) Create a shell file icon, delete the corresponding item in the file list after success, and enterstep 75;

74)创建文件图标，开始下载数据，下载完成，删除文件列表中的对应项，进入步骤75；74) Create a file icon, start to download data, and when the download is complete, delete the corresponding item in the file list, and enterstep 75;

75)依次获取下一条信息，并重复步骤72)，直至所有的信息都被下载完成；75) Obtain the next piece of information in turn, and repeat step 72), until all the information has been downloaded;

76)删除恢复标志，数据恢复结束。76) Delete the recovery flag, and the data recovery ends.
