Design And Development Of Electronic Document Security Management System Based On CryptoAPI

The current network technology advance by leaps and bounds, each big small and medium-sized enterprises are in the wide application of the computer technology, some electronic files need to archive must through the computer to complete, to achieve office automation is currently is a business unit of information rapid development is an indispensable part of, it can suffice to let employees daily schedule and work content is more clear, appear more articles of association. The use of electronic file archive management is an important part of the management of public institutions. Electronic document management mainly through the management of knowledge, and then to exchange, complement each other, through the management mode of the present office and computer network technology. Using electronic document management to save information, there are a lot of units in the more important information. Of course the electronic document also has some imperfect places, because of the use of electronic document storage information, more and more, how to manage the materials and how to ensure the information security has become a serious problem, so management information only through legal means is not enough, through certain technical means to the document for encryption control to achieve its security is essential.With the rapid development of the modern network technology, all enterprises and institutions are in the extensive application of computer technology, office automation is currently enterprises and institutions in the information construction of basic level of the typical requirements, the purpose is to standardize enterprises daily work processes and the employee’s daily behavior. Electronic document management is business management a very important management work, mainly through the methods of knowledge management to combine the electronic office document management and computer network technology, realize the units daily office network. Electronic documents as the carrier of information, contains many important information in enterprises and institutions. But the electronic document is still in the immature stage, with the increasing number of electronic documents, document security management threatened. Therefore, in the management of electronic documents also very necessary to use advanced information security technology and means of electronic document security access control, the establishment of functional comprehensive electronic document security management system.The current electronic document management model is not in place because of the management, the document information can’t effectively and quickly share to people, who want to access some information is also very difficult, more can’t ensure that the document information is safe. Through the analysis of the various problems encountered in electronic document management now, this paper presents a kind of effective management, the electronic document classification, mainly to each kind of electronic documents are encrypted and restricted permission, the compression of each type of document and then spread to the Internet, so people query will be very convenient, information security has greatly increased.This paper mainly through the security of electronic document management research, aimed at the problems currently facing electronic document management system in the electronic document security management, this paper puts forward the scheme of a better solve the electronic document security management problems. The basic idea of the scheme is the electronic document according to the different nature of the use of classified management, then provided by Microsoft Corp Crypto API encryption technology and encryption service module under compression technology processing, as a special field to save the property relationship, coupled with the relevant document to describe the field, through the security mechanism of operation system login authentication, document management system login authentication, database system, strict operation authority and document operation permissions for user login restrictions and user login with operation log, build a secure document database management system, and through the use of C/S model database under user access interface, in order to realize safe storage and access of electronic documents.
