<p>A security encoding unit performs security encoding processing on a plurality of images simultaneously, for example, an image on a front side of the document and an image on a back side of the document. The security encoding unit includes at least a first detector for detecting first security information of a first image based on a first original image data, a second detector for detecting second security information of a second image based on a second original image data, a first security encoding device for performing security encoding processing on the first original image data to generate the first image data, and a second security encoding device for performing security encoding processing on the first original image data to generate the second image data. The first original image data of the first image and the second original image data of the second image are input simultaneously.</p> |
