Abstract

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.

Claims18

Dependent claims

A security encoding unit, comprising:

a first image input unit configured to input first original image data of a first image;
a second image input unit configured to input second original image data of a second image;
an image memory;
a controller configured to store, in the image memory, either the first original image data and the second original image data or first security encoded image data of the first image and second security encoded image data of the second image on which security encoding processing is performed;
a first detector configured to detect first security information of the first image based on the first original image data;
a second detector configured to detect second security information of the second image based on the second original image data;
a first security encoding device configured to perform security encoding processing on the first original image data to generate the first security encoded image data;
a second security encoding device configured to perform security encoding processing on the second original image data to generate the second security encoded image data;
and
a reference information storage unit configured to store first reference information used for detecting the first security information and second reference information used for detecting the second security information, wherein
the first original image data of the first image and the second original image data of the second image are input simultaneously, and
the first detector uses the first reference information to detect the first security information, and the second detector uses the second reference information to detect the second security information.
