Abstract
The invention relates to a method for realizing file encryption computer software, in particular to a method for realizing computer software for encrypting the reading, modification and deletion authorities of a file by using database technology. In recent years, great progress is made in the application of office automation in China, and many enterprises start to gradually implement the office automation, so that electronic files produced in daily office work replace the conventional paper files. For the encryption technology of the electronic files, all conventional methods are used for encrypting the contents of the electronic files. The invention aims to research a method for realizing encryption on the reading, modification and deletion authorities of the file by using the database technology. Along with the further implementation of the application of the office automation and the further development of information society, the use of a file management system is expanded gradually. Therefore, the setting of the reading, modification and deletion authorities of files in a folder in the file management system by each user is a problem needing to be solved necessarily.
Description
Technical field
The present invention relates to a kind of computer software implementation method of file encryption, the computer software implementation method that erase right is encrypted is revised in especially a kind of reading of using database technology to document.
Background technology
In recent years, office automation was applied in the domestic significant progress that obtained, and a lot of enterprises have begun progressively to have implemented office automation, so the electronic document that produces in the routine office work affairs has replaced traditional paper document.Compare with traditional paper document, electronic document have is convenient to the retrieval and the statistics, stored for a long time not bad, revise easy, significant advantages such as environmental protection.
For the encryption technology of electronic document, the method for using is many at present, but all is the cipher mode that carries out at the electronic document content.This patent research be to use the reading of database technology to document, revise the implementation method that erase right is encrypted.
Along with office automation use further deeply, the further developing of information society, the use of document file management system more and more widely.Then use the user to file to each in document file management system, the reading of file is revised, and erase right has been arranged to the problem that must solve.
Summary of the invention
The objective of the invention is to: the deficiency at above prior art exists, a kind of reading of using database technology to document is proposed, modification, the computer software implementation method that erase right is encrypted, thus better meet user's demand.
The implementation method of this method is as follows:
At first set up two authority lists in database, table is the authority at file, and this table has four fields, is respectively user ID, and file ID reads authority, revises authority, erase right; Another table is the authority at file, and this table also has four fields, is respectively user ID, and file ID is read authority, revises authority, erase right.The field of all sign authorities all adopts the Boolean type data storage in two tables, and value 0 sign does not possess corresponding authority, and value 1 sign possesses corresponding authority.User ID is the uniqueness sign of user in system, and file ID is the uniqueness sign of file in system, and file ID is the uniqueness sign of file in system
The present invention also need be equipped with following assembly:
Database---be used to deposit the various documents that the user will store;
MDAC--in order to the document of storing in the accessing database.
The user uses step to be:
Step 1: the keeper is provided with the user ID sequence that allows visit at certain file, and the user of the user ID correspondence in this sequence just can visit this document folder;
Step 2: the keeper is provided with the user ID sequence that allows visit at certain file, and the user of the user ID correspondence in this sequence just can visit this document;
Step 3: the user chooses certain file, submit the visit application, the table of log file folder access rights takes out corresponding record in the MDAC accessing database, be 1 as the value of corresponding authority record and allow visit, be 0 as the value of corresponding authority record and do not allow visit;
Step 4: the user chooses certain file, submit the visit application, the table of log file access rights in the MDAC accessing database takes out corresponding record, be 1 as the value of corresponding authority record and allow visit, be 0 as the value of corresponding authority record and do not allow visit;
Step 5: the user can also revise the authority that has been provided with by MDAC, to guarantee upgrading in time of authority.
So, the supvr can be at the personalized access rights of different requirements set, thereby better realize the high-efficiency management of document.
Embodiment
Embodiment one
At first set up two authority lists in database, table is the authority at file, and this table has four fields, is respectively user ID, and file ID reads authority, revises authority, erase right; Another table is the authority at file, and this table also has four fields, is respectively user ID, and file ID is read authority, revises authority, erase right.The field of all sign authorities all adopts the Boolean type data storage in two tables, and value 0 sign does not possess corresponding authority, and value 1 sign possesses corresponding authority.User ID is the uniqueness sign of user in system, and file ID is the uniqueness sign of file in system, and file ID is the uniqueness sign of file in system
The present invention also need be equipped with following assembly:
Database---be used to deposit the various documents that the user will store;
MDAC--in order to the document of storing in the accessing database.
The user uses step to be:
Step 1: the keeper is provided with the user ID sequence that allows visit at certain file, and the user of the user ID correspondence in this sequence just can visit this document folder;
Step 2: the keeper is provided with the user ID sequence that allows visit at certain file, and the user of the user ID correspondence in this sequence just can visit this document;
Step 3: the user chooses certain file, submit the visit application, the table of log file folder access rights takes out corresponding record in the MDAC accessing database, be 1 as the value of corresponding authority record and allow visit, be 0 as the value of corresponding authority record and do not allow visit;
Step 4: the user chooses certain file, submit the visit application, the table of log file access rights in the MDAC accessing database takes out corresponding record, be 1 as the value of corresponding authority record and allow visit, be 0 as the value of corresponding authority record and do not allow visit;
Step 5: the user can also revise the authority that has been provided with by MDAC, to guarantee upgrading in time of authority.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
