Abstract: A contents filter based on similarity of content character and correlation of subject matter includes a filtering system and a disciplining system, and the contents filter isn't a filtering system used for a special subject matter but a general subject matter, the filtering contents can be obtained by leaning of the disciplining system, the filtering system and the disciplining system are installed of physical separation, the filtering system communicates with the disciplining system through the data interface, the filtering system can be installed in the input device of network information. To achieve the different filtering effect the different filtering character obtained by the disciplining system are set to the filtering system located in the different input device of network information. The present invention implements filtering through analyzing and determining text contents, and offers an intelligent and effective service of contents safety for user. The use of the filter is in great agility.

Abstract: A method for backing up and recovering data in a hard disk, used to back up data in the hard disk, including the following steps: partitioning a segment in the hard disk as a data backup area; backing up the partition status and at least one partition data needed to be backed to the data backup area; and locking the data backup area to forbid other application software or operation system to access it. The present invention can backup and recover the data in the hard disk safely and reliably and also can ensure the safety of the backup data.

Abstract: A method of computer start-up, using the configuration information of the internal and peripheral components of the computer system and information required for executing initialization of these components, and performing fast test and initialization of the components of the system. The information is pre-stored in the computer system. The present invention can perform fast start-up of the computer, significantly reduce the time needed to start up the computer, improve the efficiency of start-up of the computer, and save the waiting time for users.

Abstract: A method of backing up and recovering data in the hard disk of a computer, comprising a step of backing up data in the hard disk, including: allocating a mirror partition in a hard disk for backing up the data in a partition of the hard disk where the data need to be backed up are stored; backing up integrally the data in the backed up partition specified by the user into the allocated corresponding mirror partition; and hiding the space of the mirror partition; the method further comprising a recovery step for recovering integrally the hard disk data in the mirror partition into the corresponding backed up partition according to the instruction of the user. The present invention can back up and recovery all kinds of data in the hard disk safely and reliably.

Abstract: Disclosed is a method for implementing data backup and recovery in a computer hard disk. The method includes the following steps. First, a computer motherboard is powered up and BIOS is booted through triggering of hardware. At the same time, information about a computer bootstrap mode is stored in a recording device, the information representing a mode to start a conventional operating system or a mode to start a backup/recovery function. Then BIOS reads the information about the computer bootstrap mode from the recording device and determines which mode it represents. If the information represents a mode to start a conventional operating system, the computer is booted with a preinstalled conventional operating system. If the information represents a mode to start a backup/recovery function, BIOS operates the protection partition of a hard disk, loads the kernel of an inserted operating system and performs the backup/recovery processing.
