METHOD AND APPARATUS FOR PREVENTING ILLEGITIMATE OUTFLOW OF ELECTRONIC DOCUMENT

An apparatus and method for preventing illegitimate outflow of an electronic document are disclosed. The apparatus includes a taking-out control unit, a taking-out management server unit, and a self-response agent unit. The taking-out control unit generates a virtual disk for storing an electronic document to be controlled, and controls the taking-out of the electronic document. The taking-out management server unit authenticates whether the taking-out of the electronic document is legitimate taking-out. The self-response agent unit performs self-extinction when a result indicating illegitimate outflow is received from the taking-out management server unit.
