The computer operating system comprises an image processing module, a block searching module and a key block instability dynamic simulation module, andis used for processing the acquired image and then searching a movable block; The remote control system comprises a data storage module and an abnormal data processing module and is used for storingdata and feeding back information. The wireless transmission system is used for connection between the systems. The device is simple and convenient to use, high in working efficiency and high in practicability.

The invention provides a computer operation and maintenance management method. The method includes the steps of submitting an operation and maintenance authority approval application, verifying the operation and maintenance authority approval application and starting operation and maintenance when the operation and maintenance authority approval application passes verification. The invention further provides a computer operation and maintenance management system. The computer operation and maintenance management system comprises an operation and maintenance authority approval application module and an operation and maintenance authority verifying module, wherein the operation and maintenance authority approval application module is used for conducting operation and maintenance authority approval application, and the operation and maintenance authority verifying module is used for verifying the operation and maintenance authority approval application so as to pass or refuse the operation and maintenance authority approval application. Through the computer operation and maintenance management method and system, the problems that the operation and maintenance authority approval application and the approval process is complex and poor in timeliness can be effectively solved, and operation and maintenance security vulnerabilities are avoided, so that the operation and maintenance security is effectively controlled, and the timeliness and convenience of operation and maintenance authority altering are improved.

The invention relates to a method and a device for encrypting and decrypting Windows system partitions by fingerprints. The method includes steps of (1), starting a computer operation system, detecting whether programs are installed and/or system partition read-write request information exist or not by an encrypting and decrypting program module, if yes, performing a step (2), or returning to detection again; and (2), transmitting a command allowing for program installation and/or system partition reading and writing or not by the encrypting and decrypting program module according to whether request command of a Windows system administrator is received or not, and meanwhile transmitting operation requests to be recorded in a log module. The device comprises fingerprint recognition and acquisition equipment and a computer, wherein the fingerprint recognition and acquisition equipment is connected with the computer. Compared with the prior art, the method and the device have the advantages that damage to the system partitions from malicious content and courses can be eliminated in real time, the method is high in feasibility, and the like.
