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.

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.

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.
