1. An information processing apparatus comprising:
- an input unit configured to input image data;
an extraction unit configured to extract feature information from the image data;
a changing unit configured to change a layout of first image data input by the input unit;
a memory unit configured to store at least first feature information and second feature information in a correspondent relation, the first feature information and the second feature information being respectively extracted by the extraction unit from at least two different image data contained in plural kinds of image data having a plurality of layouts based on the first image data, the plural kinds of image data including at least the first image data and second image data of which layout is changed by the changing unit based on the first image data;
a comparison unit configured to compare third feature information extracted from third image data by the extraction unit with the first feature information and the second feature information both stored in the memory unit; and
a determination unit configured to determine that the third image data is identical to the first image data when a result of the comparison by the comparison unit shows that the third feature information is matched with one of the first feature information and the second feature information.

Abstract
Based on plural kinds of image data produced by changing a layout of input first image data, at least first feature information and second feature information are extracted and stored in a correspondent relation. Third feature information extracted from third image data is compared with the stored first feature information and second feature information. When a result of the comparison shows that the third feature information is matched with one of the first feature information and the second feature information, it is determined that the third image data is identical to the first image data.
