ABSTRACT:
This invention relates to a method and apparatus for an encryption system. The encryption system includes a server end and user's ends, in which the whole writable action about information outflow is recorded by the server end. The method of the present invention is used for encrypting the writable file by the user's ends to avoid unauthorized information outflow through out-connecting storing equipment. Therefore, all the files are just used within the Intranet of the company and the security system. Thus, the purpose of protecting information is achieved.
