Based on the above terminal hardware structure and communication network system, various embodiments of the method of the present application are proposed.
First embodiment
As shown in fig. 3, a private cloud encrypted data access method provided in a first embodiment of the present application includes the following steps:
step 310, obtaining a login request for a private cloud program;
step 320, receiving a user name and a password for logging in the private cloud program;
step 330, judging whether the user name and the password are of a public cloud account; if yes, go to step 340;
step 340, verifying the user name and the password, and entering step 350 when the user name and the password are verified;
and step 350, encrypting and accessing data in the private cloud account in the private cloud program when the user name and the password are verified.
Specifically, a private cloud is downloaded in a cloud service and installed on a mobile terminal (e.g., a mobile phone) or a fixed terminal (e.g., a computer) of a user. And after starting, receiving a user name and a password input by a user for logging in the private cloud application program.
After receiving a user name and a password for logging in the private cloud program, verifying the user name and the password, reading data in the private cloud account when the user name and the password pass the verification, and encrypting the data in the private cloud account. When the data in the private cloud account is accessed again, the data can only be read if the correct password is entered.
Further, the login user name and password are the user name and password of the public cloud. That is to say, the method and the device can achieve the purpose that the private cloud synchronizes the account data of the public cloud. The user logs in the private cloud account through the public cloud account, and in order to guarantee data security, user authentication information of the user on the public cloud can be automatically transferred to the private cloud, namely the user needs to input a user name and a password which are the same as those of the public cloud account when accessing own private cloud data. When there are accounts for multiple public clouds, the private cloud may synchronize data for the multiple public clouds, respectively or simultaneously.
Further, when the private cloud program is accessed through the local area network, the private cloud can upload files by using the FTP technology, so that the transmission speed of the files can be fastest. When there are accounts for multiple public clouds, the private cloud may synchronize data for the multiple public clouds, respectively or simultaneously.
Further, the file data in the private cloud program may be a video, an image, a document, or the like.
Further, as shown in fig. 4, the encrypting and accessing the data in the private cloud account in the private cloud program in step 330 includes:
step 410, combining the user name and the password into a character string, and using the character string as an encryption mask;
and step 420, performing exclusive or calculation on the files in the private cloud account by using the encryption masks respectively.
Specifically, if the account information of the logged-in private cloud is an account of the public cloud, the synchronized data is isolated and protected by adopting a pseudo encryption technology, that is, other users cannot normally see the synchronized data on the same terminal.
For a single file, it is the pseudo-encryption technique of the private cloud: the user name and password are used as an encryption mask to be exclusive-ored with the byte code of the file.
Example one, the byte code of a single file is 01101011, the byte code of the sum of the user name and the password is 10101000, and after the exclusive or operation is performed, the obtained byte code is 11000011.
Further, as shown in fig. 5, the accessing the data in the private cloud account in the private cloud program in step 330 includes:
step 510, extracting a user name and a password for logging in the private cloud program;
step 520, judging whether the character string of the user name and the password is the same as the encryption mask; if yes, go to step 530, otherwise, end the process;
step 530, performing reverse exclusive-or calculation on the files in the private cloud account;
step 540, reading the file in the private cloud account.
Specifically, after data in the private cloud account is encrypted, when the private cloud program is logged in again, a user name and a password during logging in the private cloud account are extracted first, whether a character string combined by the extracted user name and the extracted password is the same as a preset encryption mask is judged, if yes, reverse exclusive-or calculation is performed on files in the private cloud account, namely decryption operation is performed on the files in the private cloud account, and therefore the decrypted files are read according to instructions of a user. In this embodiment, reverse xor calculation is performed on all files by extracting the user name and the password of the private cloud account, so that the logged-in user can read all files in the account.
Taking an example one as well, when a file needs to be read, the character string formed by the user name and the password and the byte code of the file are subjected to xor again, so that 01101011, that is, the true byte code of the original file, can be obtained.
By the aid of the pseudo-encryption technology, file data stored on the private cloud can be guaranteed not to be cracked by others, and due to the rapid encryption and decryption processes, a user can completely not feel time difference when reading files, so that data security is protected, and better use experience is brought to the user.
Further, as shown in fig. 6, the accessing the data in the private cloud account in the private cloud program in step 330 includes:
step 610, receiving an instruction for reading the private cloud account file in a local database;
step 620, extracting a user name and a password for logging in the private cloud program;
step 630, judging whether the character string of the user name and the password is the same as the encryption mask, if so, entering step 640;
step 640, reading the file in the private cloud account.
The steps 610-640 described above replace the steps 510-540.
Specifically, in this embodiment, the data in the private cloud account is accessed when the user does not log in the private cloud program. In a local folder or a database of the terminal, when a user sends a file reading instruction in the folder or the database, the user can send a file reading instruction in a file clicking mode, when the instruction sent by the user for reading the private cloud account file is received, a prompt box pops up on a screen of the terminal to prompt the user to input login information, the login information can be a user name and a password of a private cloud program, the user name and the password input by the user are extracted, a character string formed by combining the user name and the password is compared with an encryption mask of an encrypted file to judge whether the user name and the password are the same or not, if the user name and the password are the same, the file is decrypted, and then the file is read.
If a plurality of files are to be read, the decryption process of the method needs to be performed on each file to ensure data security.
As can be understood by those skilled in the art, if a user has two public cloud accounts, namely, public cloud accounts 1 and 2, and includes file data of the public cloud accounts 1 and 2 in a private cloud account, when file data in the public cloud account 1 is to be read in a local database, and a user name and a password of the public cloud account 2 are to be logged in, the user name and the password of the public cloud account 2 are extracted, and it is determined that a character string combined by the user name and the password of the public cloud account 2 is different from an encryption mask formed by the user name and the password of the public cloud account 1, the selected file cannot be read.
Further, as a further improvement to the embodiment of the present application, after step 330, the following steps may also be included:
after decrypting the file, the file is shared with other friends.
Further, file data in the same private cloud program can be synchronized or/and downloaded at different terminals. For example, if the file 1 is uploaded in a private cloud program of a computer, the file 1 can be read and downloaded at a mobile phone end through a network when the private cloud program of the mobile phone end is logged in. If the file 1 is downloaded at the mobile phone end, the file 1 can be read off line. Correspondingly, the file 2 can also be uploaded in the private cloud program of the mobile phone terminal, and when the private cloud program of the computer terminal is logged in, the file 2 can be read and downloaded at the computer terminal through the network.
According to the private cloud encrypted data access method, the login request for the private cloud program is obtained, the user name and the password for logging in the private cloud program are received, and when the user name and the password are the user name and the password of the public cloud and the user name and the password are verified, data in a private cloud account in the private cloud program are encrypted and accessed. The method and the device have the advantages that the private cloud is automatically built on the terminal, the file is rapidly encrypted through the pseudo-encryption technology, and rapid, safe and guaranteed use experience is brought to a user.
Second embodiment
As shown in fig. 7, a private cloud encrypted data access method provided in the second embodiment of the present application is provided. In the second embodiment, the private cloud encrypted data access method is a further improvement made on the first embodiment, except that the method further comprises:
step 710, synchronizing data in a public cloud account into the private cloud account;
and 720, storing the data in the public cloud account to a local database.

Optionally, after the data in the public cloud is stored in the local database of the terminal, the data in the public cloud may be automatically deleted in consideration of data security.
More specifically, if the user has a public cloud account 1 and a public cloud account 2 at the same time, when a first user name and a first password of the user logging in a private cloud program through the public cloud account 1 are received, and the first user name and the first password are verified, data in the public cloud account 1 are accessed through the private cloud program, the data in the public cloud account 1 are synchronized to the private cloud account 1, and the data are stored in a local database. When a second user name and a second password of the user logging in the private cloud program through the public cloud account 2 are received, and the second user name and the second password are verified, data in the public cloud account 2 are accessed through the private cloud program, the data in the public cloud account 2 are synchronized to the private cloud account 2, and the data are stored in a local database. Namely, the data of different public cloud accounts are synchronized to different private cloud accounts and are uniformly stored in the local database. Those skilled in the art will appreciate that in other embodiments, data from different public cloud accounts is synchronized to the same private cloud account and saved uniformly to the local database.
Further, as shown in fig. 8, step 720 includes:
step 810, establishing a file storage system of the private cloud account in the local database, wherein the file storage system is in one local hard disk or a plurality of local hard disks;

step 830, connecting the detection terminal with an external mobile hard disk;
step 840, backing up part or all of the data in the private cloud account to the mobile hard disk.
Specifically, while file data is maintained, the embodiment of the application can reasonably use the disk partition of the terminal, and can select to store files in the same area or store files in a cross-area manner. On the file system of the terminal, the private cloud can also establish a set of exclusive file system as a file route to uniformly manage files in the private cloud program, and a user can inquire and view required file data through a management interface of the private cloud. Therefore, when a user queries the file, the user does not need to know the specific partition in which the file is stored, the file can be directly queried through the file routing process of the private cloud program, and the operation is very convenient.
According to the user setting or the system setting reminding period, regularly reminding the user to backup data, only inserting the mobile hard disk into a computer, and when detecting that the terminal is connected with the external mobile hard disk, the private cloud can automatically backup part of or all data in the account so as to ensure data safety. In order to save space, for the data already backed up, automatic deletion of the backed up data may be set.
Further, in order to timely release the terminal space with the smaller residual space, after the files of the user are synchronized to the private cloud, the private cloud tool on the terminal can timely prompt the user, mark file data which are not frequently checked in the files of the user, and prompt the user that the files can be released in a one-key mode.
By the method, the data storage in the private cloud is not limited by the disk partition, all spaces except the system disk are used by rendezvous, all files are displayed in the management interface of the private cloud, and the private cloud is convenient for a user to inquire and view.

Fourth embodiment
In another embodiment of the present application, based on the foregoing embodiment and fig. 1, the terminal includes a processor 110 and a memory 109;
the processor 110 is configured to execute the private cloud encrypted data access program stored in the memory 109 to implement the following steps:
acquiring a login request for a private cloud program;
receiving a user name and a password for logging in the private cloud program;
judging whether the user name and the password are of a public cloud account;
if yes, verifying the user name and the password;
and when the user name and the password are verified, encrypting and accessing data in a private cloud account in the private cloud program.
Specifically, a private cloud is downloaded in a cloud service and installed on a mobile terminal (e.g., a mobile phone) or a fixed terminal (e.g., a computer) of a user. And after starting, receiving a user name and a password input by a user for logging in the private cloud application program.
After receiving a user name and a password for logging in the private cloud program, verifying the user name and the password, reading data in the private cloud account when the user name and the password pass the verification, and encrypting the data in the private cloud account. When the data in the private cloud account is accessed again, the data can only be read if the correct password is entered.
Further, the login user name and password are the user name and password of the public cloud. That is to say, the method and the device can achieve the purpose that the private cloud synchronizes the account data of the public cloud. The user logs in the private cloud account through the public cloud account, and in order to guarantee data security, user authentication information of the user on the public cloud can be automatically transferred to the private cloud, namely the user needs to input a user name and a password which are the same as those of the public cloud account when accessing own private cloud data. When there are accounts for multiple public clouds, the private cloud may synchronize data for the multiple public clouds, respectively or simultaneously.
Further, when the private cloud program is accessed through the local area network, the private cloud can upload files by using the FTP technology, so that the transmission speed of the files can be fastest. When there are accounts for multiple public clouds, the private cloud may synchronize data for the multiple public clouds, respectively or simultaneously.
Further, the file data in the private cloud program may be a video, an image, a document, or the like.
Optionally, the processor 110 is further configured to execute the private cloud encrypted data access program stored in the memory 109 to implement the following steps:
combining the user name and the password into a character string, and using the character string as an encryption mask;
and performing exclusive-OR calculation on the files in the private cloud account by using the encryption masks respectively.
Specifically, if the account information of the logged-in private cloud is an account of the public cloud, the synchronized data is isolated and protected by adopting a pseudo encryption technology, that is, other users cannot normally see the synchronized data on the same terminal.
For a single file, it is the pseudo-encryption technique of the private cloud: the user name and password are used as an encryption mask to be exclusive-ored with the byte code of the file.
Example one, the byte code of a single file is 01101011, the byte code of the sum of the user name and the password is 10101000, and after the exclusive or operation is performed, the obtained byte code is 11000011.
Optionally, the processor 110 is further configured to execute the private cloud encrypted data access program stored in the memory 109 to implement the following steps:
extracting a user name and a password for logging in the private cloud program;
judging whether the character string combined by the user name and the password is the same as the encryption mask; if yes, reverse exclusive-or calculation is carried out on the files in the private cloud account;
and reading a file in the private cloud account.
Specifically, after data in the private cloud account is encrypted, when the private cloud program is logged in again, a user name and a password during logging in the private cloud account are extracted first, whether a character string combined by the extracted user name and the extracted password is the same as a preset encryption mask is judged, if yes, reverse exclusive-or calculation is performed on files in the private cloud account, namely decryption operation is performed on the files in the private cloud account, and therefore the decrypted files are read according to instructions of a user. In this embodiment, reverse xor calculation is performed on all files by extracting the user name and the password of the private cloud account, so that the logged-in user can read all files in the account.
Taking an example one as well, when a file needs to be read, the character string formed by the user name and the password and the byte code of the file are subjected to xor again, so that 01101011, that is, the true byte code of the original file, can be obtained.
By the aid of the pseudo-encryption technology, file data stored on the private cloud can be guaranteed not to be cracked by others, and due to the rapid encryption and decryption processes, a user can completely not feel time difference when reading files, so that data security is protected, and better use experience is brought to the user.
