Description

Technical Field [0001] The present invention relates to a cloud computing-based electronic document management system having personal information management and control function,

To an electronic document central management system, and more particularly, to an electronic document central management system based on cloud computing.

Electronic document management (EDMS) manages various types of documents in the enterprise by using computer programs and storage devices. The electronic document management system (EDMS) is an electronic document management system (EDMS) , And performs storage editing, output processing, and management.

Cloud Computing is a concept that stores all the computing resources on the network and allocates them to individual computers. It is a concept not to install the programs individually on each PC terminal and store the data. In order to build a cloud, we started from a closed private cloud that manages all the data on a central server. Recently, however, a public cloud, where a separate service provider rents servers, As a hybrid cloud, security-conscious companies are operating in a closed environment with appropriate security systems on servers leased to the public cloud.

In addition, the concept of a business that can work efficiently anytime and anywhere without departing from the conventional office work includes teleworking and telecommuting utilizing a mobile office or a video conference system that can perform work using a mobile device In the smart work system, Cloud Computing has been introduced and it has become necessary to work with EDMS (Electronic Document Management System).

On the other hand, as the damage such as voice phishing caused by leakage of personal information becomes a social problem, it is possible to prevent leakage of personal information through information systems of public institutions, businesses, and organizations that process personal information for processing personal information, There is a need for a method to do this.

Accordingly, DB access control solution and database encryption solution are used for personal information protection.

However, personal information protection is usually limited to information systems. In the centralized electronic document management system (EDMS), only a document encryption method such as a DRM solution is used. Therefore, comprehensive management of personal information Or handling of personal information is still vulnerable. For this purpose, individual personal information protection solutions and methods of handling personal information for managers are being taught.

Therefore, there is an urgent need to integrate personal information protection and electronic document management system. Especially, in the electronic document management system constructed in the cloud computing environment, centralized control of personal information for protecting personal information and electronic documents including it is urgently required This is a required situation.
