Embodiment
The setting method for computer system of following embodiment is copied to encrypted virtual hard disk with computer system data, and the user can see through data or the setting computer system that this virtual hard disk of encrypting comes the accessing computer system.Because virtual hard disk is encrypted, can not leak so can guarantee the data on the computer system.
Please refer to Fig. 1, it is the setting method for computer system process flow diagram that illustrates an embodiment of the present invention.Setting method for computer system is set a computer system, and the method is at first carried out snapshot (snapshot) to computer system, produces the database snapshot collection (step 101) of computer system.The function of snapshot collection is taking present " photo " for computer system.The snapshot collection that the different time sets up, representation database is in " appearance " of different time.So can obtain the content of computer system from the snapshot set of each time at certain time point.
The snapshot collection is to use the technology of copy-on-write, when database when the A time point is set up the snapshot collection, server can earlier be set up sparse file (Sparse File) for this database.Suppose after the A time point that change for the first time will take place the content of database page, server just can duplicate the data of this page or leaf a sparse file that arrives earlier, just the content of change can be write this page or leaf then.
After setting up the database snapshot collection, then the database snapshot collection is stored to virtual hard disk (step 103), and with virtual hard disk carry (Mount) to computer system (step 105).When carry was not to computer system, virtual hard disk only was a file at virtual hard disk, and carry just becomes a disk to computer system.Because carry needs password,, can prevent that the data in the virtual hard disk from leaking so the effect of encrypting virtual hard disk is arranged.After the virtual hard disk carry was finished, the user just can see through the stored database snapshot collection of virtual hard disk and come operational computations machine system.
Be used for the password of virtual hard disk carry to computer system can be provided by the computer system of enterprises, the password that can provide this to be used for encrypting for example by the Thin Client (Thin Client) of enterprises, and this password is stored in computer system, make computer system can decipher data on the virtual hard disk.Thus, even the user is linked to computer equipment outside the enterprise with virtual hard disk, also can deciphers, and can't decipher the contained data of virtual hard disk, and then prevent that the data of enterprises from leaking in default of password.
Please refer to Fig. 2, it illustrates the setting method for computer system process flow diagram of another embodiment of the present invention.Setting method for computer system is set a computer system, the method at first provides a null file (step 201), and with this null file formation virtual hard disk (step 203), wherein this null file can be provided by universal sequence bus unit, and this null file is to take the whole storage area of virtual hard disk.For example can use the null file that equates with carry-on dish storage volume in the carry-on dish of USB, form virtual hard disk (for example, if the dish capacity is 1G with oneself, then the size of null file also is 1G).
Since null file can after step in encrypted, need the password on the computer system to decipher; On the other hand, this null file takes whole virtual hard disk, in other words, except this null file, virtual hard disk can't store other data again, therefore the user can't be with the not encrypted zone to the virtual hard disk of the data storing in the computer system, and then unloading can guarantee so that to other computer equipment computer data can not leak.
Form after the virtual hard disk, then can be according to this virtual hard disk (step 205) of password encryption that computer system provided.In order to prevent that user's (for example enterprise staff) is downloaded to virtual hard disk with data, then with the data on the virtual hard disk again unloading to computing machine that nonbusiness had, cause computer system data to leak, therefore must encrypt virtual hard disk, for example computer system contained ascii text file or radix two computer file be encrypted.When encrypting, usually can be with file content according to the password recompile, re-use the file content that same password will encode during deciphering and be reduced into original apperance.
After virtual hard disk is encrypted, then computer system is carried out snapshot (snapshot), produce the database snapshot collection (step 207) of computer system, then the database snapshot collection be stored to virtual hard disk (step 209), and with the virtual hard disk carry to computer system (step 211).After carry is finished, the user can edit the stored database snapshot collection of virtual hard disk, with operational computations machine system (step 213), for example can edit the stored database snapshot collection of virtual hard disk, come the window display mode in the setting computer system.Because being used for the password of encryption and decryption virtual hard disk in the step 205 is stored in computer system, therefore need be connected the data that just can decipher on the virtual hard disk with computer system, so even if the user is linked to virtual hard disk the computer equipment of enterprise outside, also can decipher in default of password, and can't read data in the virtual hard disk, can prevent that just the data of enterprises from leaking.
According to the foregoing description, setting method for computer system is copied to the virtual hard disk of encryption with computer system data, and the user then can see through data or the setting computer system that this virtual hard disk of encrypting come the accessing computer system.Because virtual hard disk is encrypted, can not leak so can guarantee the data on the computer system.
Though the present invention discloses as above with embodiment; right its is not in order to limit the present invention; any the persond having ordinary knowledge in the technical field of the present invention; without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is when being as the criterion with the scope that claims were defined.
