Research And Implementation Of Disk Data Recovery Models With Filter-Driver Technology

With the computer information systems increasingly dependent and application more and more widely, the importance of computer system security has become increasingly prominent. Computer system security ,our economic security,social security and national security are closely linked, design personal interests, business survival, social stability and a national security aspects. Computer flaws and vulnerability hidden increasingly being exposed to the lawless elements to easily usurped some of the confidential data on your computer. Will also appear artificially cause errors and lack of experience in computer systems security, information security and storage technology today more and more people concerned about whether the current business or personal security information storage was caused great concern There have been many security policies and technologies to protect confidential business and personal data security and legal rights.By analyzing the disk restore ,data encryption and protection began to design a filter using Windows disk volume drive technology, the operating system kernel level implementation of disk data protection. This technique can improve the documents and data on the disk data security. We all know that when the system disk to install the "Restore" and activate the software category ,all application-level file write operations - create, modify, delete, and a variety of system settings, registry changes, even format the partition In the system have been fully restored after the restart to restore the software state of activation.Disk filter driver is closely related to the model to analyze Windows system components, and focus on the Windows filter driver, while the reduction of disk data in order to achieve the design of a reduction of the local disk protection system functions, Design a bitmap in memory management to optimize disk I/O reading and writing operations with efficiency. in the protection of documents using NTFS files system the sparse file dump file. Finally given the disk drive technology based on filtering data protection module and the overall design of test cases, but there are some problems. Need further research and practice .
