The storage file data query password is obtained by adopting an algorithm generated by a dynamic password based on a combination mode.
In an embodiment of the present application, a method for determining the feature tag information according to a target data feature includes: and determining the position of the characteristic tag information according to the characteristics of target data by adopting a file index search method, searching according to the file index path of the stored file by adopting the file index search method, and respectively searching the multi-level file indexes in the tree-shaped file index by using a sequential search method in the single-level file index.

In some embodiments of the present application, in operation, in step S10: the method comprises the steps of obtaining a storage file of a computer file system, wherein the storage file adopts an LINUX system, the storage format, the content or the size and the like of the storage file are not limited, making an image file of the storage file, and extracting characteristic data of the image file to form target data characteristics.
The adopted LINUX system has a dynamic storage function, and the partition size can be dynamically adjusted under the condition of not re-partitioning; the disk encryption is divided into three encryption models; encrypting the file data of the computer by using a single key or multiple keys without encryption; in terms of data integrity, in order to ensure data integrity, the LINUX system adopts an encryption and decryption technology for computer file data.
In order to perform electronic matching, data acquisition is usually realized by mirroring, and a mirror image file is an effective way of protecting evidence and providing matched data, and is an important link of computer file data matching, that is, a storage file is a mirror image file.
In the embodiment of the application, the image file is obtained by copying the original data bit by bit to generate the image data completely consistent with the original data, and the image data can be used for an evidence for analysis in a simulation environment. Creating an image file and selecting source file data needing to be imaged; then selecting a mirror image format, and inputting relevant information after a path is formed everywhere; after the mirror image is finished, the generated mirror image can be automatically checked, the check is to verify whether the hash value generated by the new mirror image is the same as the file hash value of the source file data, and when the check values are the same, the generated mirror image file and the source file can be proved to be the same.

If the user mismatches a certain file, the user can reply if the user has made the mirror image file before; if the user does the mirror image, the file under the mirror image file is lost and cannot be inquired. Conversely, if the user's target data source is corrupted and all data is lost, the signature tag can only be queried on the nearest one. The latest generated data can be lost, and the mirror image can quickly inquire all the data, so that the continuity of the service is ensured. The signature tag information formed by the rapid processing of the image file confirms that the data can be securely processed.

If the storage file adopts a FAT64 encryption format, the FAT64 encryption format means that the corresponding storage area is encrypted, and a FAT64 encryption and decryption password needs to be input, the storage file needs to be decrypted first, and then the storage file needs to be operated.

The feature tag information generally refers to security settings for querying a host and controlling system permission, so that security audit of a super user can be realized, the feature tag information needs to be matched with a username and a password after being audited, and if the feature tag information is not matched with the username and the password, the system permission cannot be obtained for corresponding operation.

If the storage file adopts the FAT64 encryption format, the storage file needs to be encrypted after being decrypted, and the storage file data inquiry password is written and then encrypted, so that the inquiry password is in an encrypted state. Corresponding to the BASE64 decryption algorithm, the encryption process may use the BASE64 encryption algorithm to write the generated query password into the image file, and after the MacOS operating system is started, the matching operation may be performed in the image file, that is, the image file is matched in step S40, and the user query password does not need to be input because the feature tag information is matched.
