This invention relates to the field of computer file system technology, and in particular to a file system kernel service and high-concurrency scheduling method based on a unified protocol. The method includes the following steps: Step 1: Starting a receiving thread and a file operation thread on the server side, the file operation thread including a lightweight thread and a heavyweight thread; Step 2: Listening to the network port through the receiving thread to receive JSON-formatted requests sent by clients, the requests containing timestamps and operation types; operation types include copy, move, create directory, delete, list, and restore; Step 3: Storing the received requests in a receiving queue; Step 4: Retrieving requests from the receiving queue and distributing them according to the operation type; Step 5: Executing the operation; This invention exposes file operation capabilities through independent processes and a unified JSON protocol. The six types of operation semantics, as well as the semantics of abort and recoverable deletion, are all uniformly defined at the protocol layer. The dual-type threads and request queue improve throughput and stability under multiple clients and large-scale tasks.

This invention discloses an automatic computer protection system and method, relating to the field of computer file security protection. The technical solution includes: detecting user idle time; identifying sensitive tabs in the browser when the user is about to leave, and extracting the ORB feature point set of their content area as a content fingerprint; creating a Gaussian blur overlay window when the user has left, tracking the positional changes of the content area through feature point matching and affine transformation, and dynamically adjusting the position and size of the overlay window so that the overlay always follows the movement of the file content; and destroying the overlay window when the user returns, restoring the file to normal display. This invention, through content area tracking based on visual features and progressive blurring, solves the problem of sensitive file content being exposed and background tasks being interrupted when a user is briefly away, achieving fine-grained protection at the file and tab levels, and helping to improve the security of computer files in the office environment.

A deterministic finite automata (DFA) is used by an extended Berkley packet filter (or “eBPF”) to monitor file system operations and non-file system operations. The DFA is stored as an eBPF map. Before a kernel of an operating system executes any file system operation, the kernel runs an eBPF program that queries the DFA for a filename associated with the system operation. The DFA represents safe / suspicious filenames associated with computer files. If the filename matches the DFA, then the kernel notifies a cybersecurity agent. The cybersecurity agent may then block or allow the file system operation, depending on whether the filename is safe or suspicious. The DFA stored in the extended BPF thus greatly improves computer functioning by very quickly and simply identifying safe / suspicious operations.

The application provides a file acquisition method and device, computer equipment and a storage medium, and the method comprises the following steps: acquiring the clipboard data of a first target object, wherein the clipboard data comprises the storage path information of a first file and a first operation type performed on the first file; after the clipboard data is written into the clipboard corresponding to a second target object, the storage path information of the first file is replaced by the storage path of a second file which is pre-constructed, wherein the second file is a file created on the second target object; when a preset operation is performed on the second file, response information corresponding to the preset operation is generated; the response information is fed back to the first target object side, so that the first target object transmits the operation result to the storage path of the second file according to the response information. The application can realize that the user can copy or cut any local file as operating a local computer file, and paste the file anywhere in the cloud desktop.

Data backups are performed in multiple blockchain environments. Digital pictures, movies, computer files, apps, and any other electronic data may be automatically backed-up, or duplicated, to multiple blockchain networks. First, an electronic data is written to a first blockchain network. A second, different, blockchain network is automatically selected based on many factors and / or parameters. Then, the electronic data is written to the second blockchain network. Still more duplicate copies of the electronic data may be redundantly written to third, fourth, and more blockchain networks. Any of the blockchain networks may send a confirmation that confirms the duplicate copy was written. One or more cryptographic proofs may be generated to prove the duplicate copies were stored to the multiple blockchain networks.

A Wearable Medical System (WMS) that implements a wearable cardioverter defibrillator (WCD), includes a microphone and related improvements. The microphone can be on the same dongle as the cancel switch of the WCD. A user trigger module may permit the patient to perform a deliberate act and, in response, the system may start recording audio from the ambient sounds, including their own voice, and / or start recording the ECG. The deliberate act may even be a voice command by the patient that is parsed by a voice recognition module. The WMS may continuously record audio and then continuously discard it, and further stop the discarding if it detects a recording trigger. The WMS may create an exportable computer file that has audio-related data, which can have playable sound data or transcribed voice data.

The present application belongs to the field of computer file system, and particularly relates to a method and system for restoring temporary data in unused space of a disk, wherein the method comprises the following steps: S1, acquiring all disk running data in a networking state of a user computer system; S2, locating a data area of the disk, extracting temporary data in unused space of the data area, and classifying the temporary data in the unused space according to preset file information features to generate a retention file feature table; and S3, reading the retention file feature table, and processing according to a preset restoration measure according to the completeness of the retention file feature table. The present application can solve the problems of high restoration difficulty and high restoration cost in the prior art when data is restored under the premise that the user's backup awareness is weak.

A method for securing one or more computer files includes obtaining at a computer device having a file and at a handset device data based on movement of at least one of the devices with the respect to the other device and generating an encryption key based on the obtained data at each of the devices wherein the key at each of the devices is substantially the same, and encrypting the file on the computer with the encryption key, discarding the computer encryption key and saving the handset encryption key. Later, the encryption key saved on the handset can be used to decrypt the encrypted file. Further, the method can be used to secure a plurality of files with the generated encryption key.
