Abstract

A method of managing data contained in a file is provided, including: extracting location information contained in a print data file; determining whether identical location information exists between the extracted location information and input location information; and if it is determined that there is If the same location information is found, the print data contained in the print data file is analyzed. A method of managing data contained in a document is provided, including: extracting location information by reading the document; determining whether identical location information exists between the extracted location information and input location information; and if it is determined that identical location information exists location information, copies the information contained in the document.

Description

Technical field [0001] The invention relates to data management. More specifically, the present invention relates to a data management method and device for allowing the information contained in the file or document to be known only when the same location information exists between the location information extracted from the file or document or the document and the input location information. Data to prevent illegal outflow of data. Background technique [0002] The conventional data management device creates a print data file by encrypting the print data using an authentication key prepared in advance. Here, the print data may be document data or image data. [0003] Since the print data file created by the conventional data management device is encrypted, a third party who expects to know the content of the print data must decrypt the print data file. In order to decrypt the print data file, the third party must know the authentication key used for encryption. [0004] Unfortun...
