The invention provides a clinical test data table collaborative auditing method and system based on file state driving, and relates to the technical field of clinical test data processing.The method comprises the steps that firstly, an initial file set of clinical test data table files is obtained, and the initial file set comprises a to-be-audited table file unit and a metadata description information set; analyzing the data unit structure to generate a table data unit topological graph; generating an auditing operation event in response to the auditing operation; inputting the auditing operation event into a constraint propagation analysis model to determine an affected associated data unit node set; and finally, generating a file state driving instruction based on the associated data unit node set, and triggering the cooperative auditing terminal to auditing the associated data field. According to the invention, data can be accurately positioned, the structure can be visually presented, the influence range can be rapidly determined, automatic coordination auditing is realized, and the clinical test data auditing efficiency and accuracy are improved.

The invention discloses an MP4 video file breakpoint continuation method, which comprises the following steps of: constructing a standard MP4 packaging structure, and fixing a metadata container MOOV at a reserved position at the tail of a file; after the first recording is finished, a current complete MOOV is generated and overwritten to a fixed position at the tail of the file, and resuming information is recorded and comprises a file serial number and a suspension frame serial number; analyzing the secondary recorded file, reading the content of the target file and the MOOV according to the resuming information, analyzing a sample table box STBL based on the MOOV to obtain the information of all frames of the current MP4 file, generating a frame information linked list of the current file, and judging the state of the file; overwriting the data based on a file state application continuation strategy, obtaining a file offset corresponding to a suspension frame through a suspension frame serial number and a frame information list, starting overwriting, and updating the frame information list; and generating the MOOV content according to the frame information list, judging whether the initial position and the size of the suspension frame have coverage or an intermediate interval with the original frame, and updating the resume information after processing.

Systems and methods of persistent file protection integrate cloud-based backups with EDR file protection. Use of local persistent file cache (PFC) data with cloud-stored file segments, facilitates reconstruction of file states from multiple sources. File storage and retrieval efficiency are optimized, even when local session caches are invalidated or when extensive file modifications exceed storage quotas.

The application discloses a file storage management system based on RFID, which comprises a file cabinet, a label configuration module, an information acquisition module, a first-level read-write device and a file management module. The file cabinet is internally provided with a plurality of storage spaces. The label configuration module comprises a plurality of electronic file labels and an electronic wake-up label. The information acquisition module acquires the position coordinates of the storage spaces and the characteristic information of entity files. The first-level read-write device is used for emitting radio frequency energy to form an electromagnetic field. The position coordinates, file state information and characteristic information are input into the corresponding electronic file labels. The file management module comprises a second-level read-write device and a database. The file management module acquires a borrowing request, obtains the ID of the electronic file label corresponding to the entity file to be borrowed through the database searching, and inputs the ID of the electronic file label into the electronic wake-up label through the second-level read-write device. The application greatly simplifies the process of borrowing and returning entity files by employees and improves work efficiency.

The embodiment of the invention provides a file processing method and device, equipment, a storage medium and a program product, and the method specifically comprises the steps that a downloading request of a to-be-downloaded file is received, and the downloading request comprises file elements of the to-be-downloaded file; in response to the downloading request, querying file elements of a to-be-downloaded file by using a Bloom filter to obtain a first query result; wherein the configuration parameters of the Bloom filter are dynamically adjusted based on the system fusion state value of the Bloom filter, and the system fusion state value represents the health state of the Bloom filter; when the first query result represents that the file state of the to-be-downloaded file is a downloaded state, querying file elements of the to-be-downloaded file in a database to obtain a second query result; and based on the second query result, executing a processing operation on the to-be-downloaded file. According to the embodiment of the invention, the misjudgment rate of the Bloom filter can be effectively reduced, so that repeated downloading of the file can be effectively avoided.

The embodiment of the invention provides a file change monitoring method and device, equipment and a medium, and the method comprises the steps: reading persistent file metadata of a monitoring directory corresponding to a selected file monitoring mode according to the selected file monitoring mode when a file monitoring assembly is started; performing deserialization processing on the persistent file metadata to generate historical file metadata of a monitoring directory; when timing scanning is started, metadata of the monitoring catalog at the current moment is analyzed, and current file metadata of the monitoring catalog is generated; and matching the historical file metadata with the current file metadata to generate a file change result generated by the monitoring directory. By utilizing the method, the directory file state can be recovered to the appointed time point through the persistence of the file metadata, so that the business continuity is ensured in the aspect of file monitoring. By setting different file monitoring modes, file change events in different modes can be processed and played back, and the requirement for diversity of the monitoring modes is met.

Embodiments of the present disclosure disclose a file synchronization method, a file updating method, an apparatus, an electronic device and a medium. A specific implementation of the method comprises: determining a file state of a target configuration file; in response to determining that the file state indicates that the target configuration file is updated, determining front-end service information matched with the target configuration file; and synchronizing the target configuration file to at least one first target server corresponding to the front-end service information according to a synchronization type corresponding to the target configuration file, so that the at least one first target server performs file hot updating according to the target configuration file. The implementation improves the synchronization efficiency of the configuration file.

The embodiment of the present disclosure discloses a kind of safe office method and device of mobile storage device, it is related to information security technical field, by the safe office device of mobile storage device implementation, the device includes fuse monitoring module, including: the file directory state of the first office software is acquired, wherein the file directory state includes creation file state and click file state;When the file directory state is the creation file state, receive Create message;According to the Create message, create first same name file in mobile storage device;When the file directory state is the click file state, receive open message;According to the open message, open the second same name file in mobile storage device.Solve the technical problem that the present art due to file transfer frequency is more, and disc cannot be edited, leading to there is high file leakage risk, and poor user experience.
