Abstract

The present invention provides a method for creating an electronic document file comprising monitoring creation and changes of an electronic document file, receiving a policy file including document level set-up information and security policy, searching for words associated with business information from the text data retrieved from the electronic document file, computing an exposure score of the electronic document file based on the number of times for words associated with business information being searched and document level set-up information, assigning a document level to the electronic document file based on the exposure score, and inserting a watermark to text of the electronic document file to be displayed on the client device based on the user's personal information received from the server. Accordingly, leakage of business documents for electronic document files including business information can be prevented by providing pre-security and post-security measures stronger than conventional measures.
