A method for locking hard disk partition safely

Abstract

The invention relates to a method, which is used to lock the disc partition safely through BIOS layer and OS layer. The invention separates a disc into many working partitions with self-defining locking through the read-write control technique of the disc magnetic track. Data of different users in these partitions is kept secret on the one hand, but provides good interactivity within a permission range on the other hand. That is to say, many persons may share one computer safely, and one PC is visualized to be many PCs by physical means. Thus the multi-users state of the workstation is realized, and the network isolation card function is implemented with software. Regardless of the disc type, with perfect compatibility, the invention controls the disc partition data effectively, without influence of the reading-writing speed. The locking function is implemented costively.

Description

Technical field [0001] The invention belongs to the hard disk data security protection technology in the field of computer information security, is a method for safely locking hard disk partitions based on BIOS layer and OS layer, and supports multiple operating systems. Background technique [0002] The development of network technology and the general promotion of network applications and the application of computers have penetrated more and more into key fields such as government, finance, and national defense, as well as various fields of society and economy. Information security in these fields has become particularly important. The root of network information security lies in the security of data. When hackers or viruses invade, steal or destroy the data on the hard disk, the hard disk lock can provide effective security for the hard disk data. The basic method of the existing hard disk lock is to lock the hard disk The locking method of the entire hard disk is realize...

The root of network information security lies in the security of data. When hackers or viruses invade, steal or destroy the data on the hard disk, the hard disk lock can provide effective security for the hard disk data. The basic method of the existing hard disk lock is to lock the hard disk The locking method of the entire hard disk is realized by cutting off the electrical signal or through the access control of the hard disk. Although the above method realizes the function of hard disk lock, it cannot enable users to effectively access data, let alone interact flexibly, and cannot realize Multiple users can safely share one PC; existing hard disk locks cannot implement custom locking partitions and user settings. With the continuous improvement of users' requirements for hard disk locks, the lost scalability of previous hard disk lock methods can no longer satisfy users. needs
