Before explanation based on network data file control-management system disclosed in this invention and data file control and management method thereof, first the noun of institute of the present invention self-defining explained, data file of the present invention and external data file refer to can be for the file of computer access, wherein each data file include file authority and file class, take file permission as example, it can be to reading, write and the operation such as execution limiting; Take file class as example, it can comprise research and development, design, checking, manufacturing, sale, logistics, analysis, maintain secrecy ... etc. classification.
Be noted that especially the file permission of data file can record owner and group name, and represents different rights with nine bits on reality is implemented, bit " 1 " representative allows; Bit " 0 " representative does not allow, wherein from left to right first represents sequentially to the 3rd bit that " owner's the authority that reads, writes and carry out ", the 4th to the 6th bit sequentially represent " with the authority that reads, writes and carry out of group ", the 7th to the 9th bit sequentially represents " anyone authority that reads, writes and carry out ", when file permission is " 700 ", its binary representation is " 111000000 ", so representative only has the owner can read, write and carry out.
Below in conjunction with accompanying drawing data file control-management system and the method thereof that the present invention is based on network is described further, see also Fig. 1, Fig. 1 is the system block diagrams that the present invention is based on the data file control-management system of network, comprises: database service end 110, client 120 and keyholed back plate service end 130.Wherein, database service end 110 is in order to the storage data file, and much more no longer each data file include file authority and file class owing to data file explains in the noun of previous self-defining, so to give unnecessary details at this.
From the above since client 120 only the transfer operation instruction is to keyholed back plate service end 130, and self-control tube service end 130 receives the operating result that produces after described operational order is carried out.Therefore, can't transmit complete data file between client 120 and the keyholed back plate service end 130, so can avoid data file to be stolen.
Keyholed back plate service end 130 is in order to interconnect with database service end 110 and client 120 respectively by network, and this keyholed back plate service end comprises: authentication module 131 and control module 132.Wherein, the log-on message that authentication module 131 transmits from client 120 in order to checking, generation login license and obtain authority information after being proved to be successful, and will login license and be sent to client 120, owing to verify that log-on message is prior art, so much more no longer to give unnecessary details at this, be noted that especially on reality is implemented, during authentication module 131 authentication failed, can produce information warning and be recorded in the keyholed back plate service end, this information warning can be verified successful client 120 and browse.
Control module 132 is in order to carry out operational order from client 120 to produce operating result and to be sent to client 120 according to authority information, for example: suppose that authority information is " chief executive ", then control module 132 allows to carry out all operations instruction from client 120; Suppose that authority information is " user ", then only allows the operational order of browsing data file.In addition, when in the process of executable operations instruction, needing access of data files, control module 132 also can be compared file permission and the file class of authority information and data file, and when comparison conforms to, allows the operational order access of data files of client 120.For instance, the owner of tentation data file is " chief executive ", and the operation that the file permission of data file allows the owner to read, write and carry out, so when authority information is " chief executive ", control module 132 will be judged as comparison and meet, and allow this data file is read, writes and carries out.Be noted that especially, after producing operating result, control module 132 can be encrypted this operating result, and allow the operating result after 120 pairs of encryptions of client to be decrypted, its ciphering process can be encrypted by public-key cryptography (Public Key), and is decrypted by the private cipher key (Private Key) of client 120.
On reality is implemented, also can arrange in pairs or groups the again file class of data file of control module 132 is judged, for example: no matter authority information is " chief executive " or " user ", when if its file class of wanting the data file of access is secret, then forbidden energy (disable) to this data file copy, the mobile and operational order that transmits, in order to reduce the possibility that data file is replicated or steals.Although the present invention is in the above-mentioned mode judged of collocation file class that illustrates, yet do not do restriction with this, in other words, control module 132 also may be in order to accept or reject between administrative convenience and security, and only for authority information for " user " come forbidden energy to this data file copy, the mobile and operational order that transmits.
In addition, said system also can comprise the external service end 140 that stores external data file, this outside service end 140 interconnects by network and keyholed back plate service end 130, and allows keyholed back plate service end 130 to make data file in the database service end 110 and the external data file in the external service end 140 carry out exchanges data by the operational orders of carrying out.On reality was implemented, manufacturer or department that described external service end 140 can offer supply chain logined, so that manufacturer or department are sent to the data such as instant sale and logistics this outside service end 140 and save as external data file.In other words, described external service end 140 is to offer the manufacturer of supply chain or the usefulness of department's (being the external staff of company) immediate feedback data, operates but not offer the personnel of intra-company such as client 120.
Then, see also Fig. 2 A to Fig. 2 C, Fig. 2 A to Fig. 2 C is the method flow diagram that the present invention is based on the data file control and management method of network, be applied to have database service end 110, the network environment of client 120 and keyholed back plate service end 130, its step comprises: provide data file at database service end 110, each data file include file authority and file class (step 210); Client 120 transmits log-on message to keyholed back plate service end 130 (step 220); Keyholed back plate service end 130 checking is from the log-on message of client 120, generation login license and obtain authority information after being proved to be successful, and will login and permit and be sent to client 120 (step 230); The transfer operation instruction was to keyholed back plate service end 130 (step 240) after client 120 received the login license; Keyholed back plate service end 130 is carried out operational order from client 120 to produce operating result and to be sent to client 120 according to authority information, and compare when conforming at the file permission of authority information and data file and file class, allow the described data file of operational order access (step 250) of client 120; Client 120 receives the operating result of described operational order to export (step 260).Pass through above-mentioned steps, can carry out keyholed back plate by the data file that 130 pairs of keyholed back plate service ends are stored in database service end 110, and the operational order of carrying out client 120 transmission is back to client 120 to produce operating result, avoids client 120 storage data files and data file to be stolen in transmission course.
Be noted that especially when step 230 authentication failed, can produce information warning and be recorded in keyholed back plate service end 130, and the client 120 that allows to be proved to be successful is browsed this information warning (step 231); When the instruction of step 250 executable operations, more can make the data file of database service end 110 and the external data file of external service end 140 carry out exchanges data (step 251) by the operational order of carrying out.In addition, at the operating result (step 2501) that step 250 produces, be resent to client 120 after it can be encrypted, and allow the operating result after 120 pairs of encryptions of client to be decrypted (step 2502); And in the situation of the operational order access of data files (step 2503) that allows client 120, in the time of can being secret at the file class of its data file, the operational order (step 2504) that forbidden energy copies, moves and transmit, the possibility that is replicated and steals to reduce data file.
Carry out following explanation below in conjunction with Fig. 3 in the mode of embodiment, see also Fig. 3, Fig. 3 is for using the present invention in the synoptic diagram of manufacturing management system.Wherein, the equipment of client 120 for providing the user to operate, as: PC, notebook computer, personal digital assistant ... etc.; 130 of keyholed back plate service ends can be considered department system, as: manufacturing sector, research and development department, sales department ... etc.; Client 120 in order to the transfer operation instruction to keyholed back plate service end 130, in order to come the executable operations instruction by keyholed back plate service end 130, and return to client 120 exporting by the operating result that keyholed back plate service end 130 produces the executable operations instruction, as: show by display.Can be considered data center as for 110 at database service end, in order to storing relevant all data files that may use in the chain of making, as: test file, stock file, research and development file, sale file ... etc..
Take research and development department as example, client 120 interconnects with keyholed back plate service end 130 as development system, and keyholed back plate service end 130 more interconnects with database service end 110 as data center.Thus, when the research staff wants to browse the research and development file (being that file class is the data file of " research and development ") that is stored in database service end 110, can be first by client 120 input account numbers and password so that client 120 produce corresponding log-on messages and be sent to keyholed back plate service end 130 so that keyholed back plate service end 130 these log-on messages of checking are identified research staff's identity.
Then, the authentication module 131 of keyholed back plate service end 130 is after identification is finished to this log-on message, can produce the login license and obtain corresponding this research staff's authority information, and will login and permit and be sent to client 120.After client 120 receives the login license that keyholed back plate service ends 130 transmit, client 120 will according to research staff's operation (for example: click browse the button request and browse the research and development file with cursor), be sent to keyholed back plate service end 130 with corresponding operational order.
Next, after keyholed back plate service end 130 receives this operational order, control module 132 will be carried out the operational order that the research and development file is browsed in request according to this research staff's authority information.The authority information of supposing the research staff is " abc; The research staff ", wherein " abc " is research staff's account number or title; " research staff " is group name.So, control module 132 is carried out when asking to browse the operational order of research and development file, is the tabulation of the data file of " research and development " with All Files classification in the Query Database service end 110, and this tabulation is back to client 120 as operating result.Thus, be positioned at the title that the research staff " abc " of client 120 can be by screen browsing data file.
Afterwards, when research staff " abc " wish is opened one of them data file, can click the data file that wish is opened by cursor equally, client 120 can produce corresponding operational order and be sent to keyholed back plate service end 130 according to this operation equally.Receive the operational order of request turn-on data file when keyholed back plate service end 130 after, control module 132 can be " abc with authority information; The research staff " compare; suppose that file permission collection of record group name is called " research staff ", file class is " research and development "; control module 132 will be judged as to compare and meet so, and this data file of access is sent to client 120 with its content as operating result and shows by file permission and the file class of the data file of opening with wish.
Then, take sales department as example, client 120 interconnects with keyholed back plate service end 130 as marketing system, and keyholed back plate service end 130 more interconnects with database service end 110 as data center.Thus, the sales force can operate in client 120 equally, and by client 120 log-on message and operational order is sent to keyholed back plate service end 130.What they were different from research and development department is, because the sales force has different authority informations with the research staff, so the data file of control module 132 access that allows is also not identical.Be noted that especially, when wanting inter-department cooperation, only need to change file permission or file class, the personnel that data file can be offered different departments use jointly, and for example: the file permission of data file can be made as anyone and all can read or file class is made as " research and development, checking " to offer research staff and tester use.
From the above, the present invention is in practical application, keyholed back plate service end 130 can be complied with different departments as verification system, manufacturing system, logistics system, marketing system, analytic system, development system, design system ... etc., and provide connected client 120 to operate and the display operation result, the needed data file unification of each system is stored by database service end 110 and provides, and data file can not be sent to client 120, avoid data file via the user of client 120 with the Portable disk pirate, or in the transport process of data file, stolen.
At last, the present invention more can provide external service end 140 with as supply chain high in the clouds for logistics and sale, and stores external data file in this outside service end 140, and this outside data file can be logistics and the sales data of the external staff of company feedback.On reality was implemented, external service end 140 interconnected with keyholed back plate service end 130, and external service end 140 allows keyholed back plate service end 130 to make data file and external data file carry out exchanges data by the operational order of carrying out.Thus, the personnel of logistics or sales department just can pass through client 120 transfer operation instructions, the 130 executable operations instructions of keyholed back plate service end are upgraded sells or logistics data, for example: upgrade sales data older in the database service end 110 according to sales data up-to-date in the external service end 140, and the process of this renewal or exchanges data is only by actual transmitting data file is just arranged between database service end 110, keyholed back plate service end 130 and the external service end 140.
In sum, difference between the present invention and the prior art is that the data file that is stored in database service end 110 by 130 pairs of keyholed back plate service ends carries out keyholed back plate as can be known, and the operational order of carrying out client 120 transmission is back to client 120 to produce operating result, avoid client 120 storage data files and data file in transmission course, to be stolen, can solve the existing problem of prior art by this technological means, and then reach the technology effect that improves documentary safety in data.
