<p>The present invention relates to a method for improving document security in an image forming apparatus. The method comprises the steps of copying or printing an original document in an apparatus capable of performing an encryption printing process; compressing an image read in a scan step; encrypting the compressed image; printing the encrypted content with a specific security code; scanning a document in which the encrypted content is printed with the specific security code; releasing a compression and the security code read through the scan step; and printing the security code and the released original document. The method prints the security code and the released original document and has a good point to make that a normal person is unable to understand content by printing the content as a code which is unable to be read with the naked eyes. Therefore, the content of the document is unable to be confirmed without decoding of the present invention when the document is exposed. So, the present invention has an effect to have the reinforced document security.</p> |
