s110, dividing the acquired target file to obtain a file block.
The traditional file storage mode is to store the whole file in a certain storage space, so that the whole file is easy to leak, and the security is poor. Therefore, the embodiment performs distributed storage on the file to be stored, namely, the file to be stored is divided into a plurality of file blocks, and then each file block is stored respectively, when the information of one file block is leaked, the leakage of the whole file information is not influenced, and the information safety is ensured. The embodiment refers to a file to be stored as a target file. Optionally, the target file may be determined according to file information input by the user, where the file information may include a file name, a file identifier, and a current location of the file to be stored.
Alternatively, the target file may be divided according to the importance level of the content included in the target file, for example, the target file includes four parts of content, and the importance levels of the parts are different, so that the target file may be divided into four file blocks according to the importance levels. The target file may also be divided according to the size of the target file, and the sizes of the file blocks may be the same or different, and the size of the target file is 6M, and may be equally divided into three file blocks, each file block having a size of 2M. In order to facilitate subsequent access, a certain identifier may be set for each obtained file block, so as to restore the target file.
S120, storing the file blocks in the corresponding storage spaces according to a preset mode, and forming an index table based on the storage positions of the file blocks.
Optionally, each file block may be encrypted and then stored in a different storage space, where the encryption manner of each file block may be the same or different, and in order to improve security, different encryption manners may be used for each file block. Optionally, encryption modes with different grades can be set according to the importance degree of each file block. After each file block is stored, an index can be created according to the storage position of each file block, and when the target file needs to be accessed, the storage position of each file block can be rapidly determined according to the index. The file storage mode solves the problem that information is easy to leak caused by traditional simple password storage, meanwhile, a special secret system is not needed, and storage cost is reduced.
The first embodiment of the invention provides a file management method, which is characterized in that a file block is obtained by dividing an obtained target file, each file block is stored in a corresponding storage space according to a preset mode, and an index table is formed based on the storage position of each file block. Compared with the prior art, the embodiment of the invention divides the obtained target file into a plurality of file blocks and stores the file blocks in the corresponding storage space, thereby realizing the distributed storage of the target file and ensuring the safety of the file.
On the basis of the above embodiment, before S110, further includes:
acquiring a file storage request, wherein the file storage request comprises a file identifier and initial position information;
and determining the target file to be stored according to the file identification and the initial position information.
The file identifier is used to uniquely identify the file to be stored, and may be, for example, the name or ID of the file, or a combination of the name and ID. The initial position information is the initial position of the file to be stored. And obtaining the target file to be stored according to the file identification and the initial position information.
On the basis of the above embodiment, alternatively, each file block may be stored by:
creating a file number of each file block according to the content of each file block;
encrypting each file block, and storing each encrypted file block in a corresponding storage space;
and creating indexes corresponding to the file blocks according to the file numbers of the file blocks and the position information of the corresponding storage spaces to form an index table.
In order to facilitate the restoration of the target file, the embodiment numbers each file block after dividing the target file, each file block corresponds to a unique file number, and the file numbers and the dividing sequence of the target file remain corresponding. In this embodiment, when each file block is stored, each file block is encrypted according to a certain encryption mode, so as to save storage space, when the file block is larger, the encrypted file block can be compressed, and the compressed file block is stored in the corresponding storage space.
Optionally, in this embodiment, an index may be created according to the file number and the storage location of the corresponding file block, and when a certain file block needs to be accessed, the storage location of the file block may be quickly determined by looking up the index table.
