Abstract

An image forming method includes the following steps: using the code key to convert the image data into the coded data having the code string; forming the small pattern string on the printing paper through printing the small pattern, wherein each small pattern is corresponding to the code composing the coded data; recording the code key or the data corresponding to the code key on the record medium combining with printing paper; prompting the user to input the deciphering key; reading out the data logging from the record medium; determining whether the deciphering key is consistent with the data logging or not; scanning the small pattern string recorded on the printing paper when the deciphering key is consistent with the data logging; converting the small pattern string scanned from the printing paper into the code string; using the deciphering key to decode the code string into the original image data and print the image on the printing paper on the basis of the image data.

Description

technical field [0001] The present invention relates to an image forming method and an image forming apparatus which can be used or used as printers, copiers, facsimile machines, MFPs (Multi Function Peripherals), etc., especially for forming coded patterns on originals and decoding the coded patterns. Background technique [0002] A conventional example in the related art is Japanese Laid-Open Patent Application No. 2002-175169 (hereinafter referred to as Patent Document 1). Patent Document 1 introduces a method of converting image data into a coding pattern before printing out, so that the confidentiality of the content can be protected even if the printing medium is set. [0003] However, in this case, if a wrong decoding key is input when decoding encoded data, unrecognizable content will be printed, and this will waste printing paper. Also, if a weak encoding system is used, it is possible to deduce the decoding key by associating the input key with the output content,...
