1. An apparatus for determining an availability of encoding data into an image, the apparatus comprising:
- an input/output characteristic applying unit that applies an input/output characteristic of a feature amount, the input/output characteristic being related to a combination of an output device and an input device, to an image in which the data is embedded using the feature amount, wherein the output device outputs the image in which the data is embedded to a medium, and the input device inputs the image;
an embedding-availability determining unit that determines an availability of embedding the data in the image, without outputting the image in which the data is embedded to the medium, using the image to which the input/output characteristic is applied by the input/output characteristic applying unit; and
a result output unit that outputs a result of determining the availability by the embedding-availability determining unit.

Abstract
An embedding-availability determining unit determines an availability of embedding data into an image based on an input/output characteristic of a predetermined feature amount related to a combination of an output device that outputs an image in which the data is embedded to a medium and an input device that inputs the image that is output to the medium. A result output unit outputs a result of determination by the embedding-availability determining unit.

8. A computer-implemented method of determining an availability of encoding data into an image, the method comprising:
-
applying an input/output characteristic of a feature amount, the input/output characteristic being related to a combination of an output device and an input device, to an image in which the data is embedded using the feature amount, wherein the output device outputs the image in which the data is embedded to a medium and the input device inputs the image; determining an availability of embedding the data in the image, without outputting the image in which the data is embedded to the medium, using the image to which the input/output characteristic is applied at the applying; and outputting a result of determination at the determining. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer-readable recording medium that stores a computer program for determining an availability of encoding data into an image, wherein
the computer program causes a computer to execute: -
applying input/output characteristic of a feature amount, the input/output characteristic being related to a combination of an output device and an input device, to an image in which the data is embedded using the feature amount, wherein the output device outputs the image in which the data is embedded to a medium and the input device inputs the image; determining an availability of embedding the data in the image, without outputting the image in which the data is embedded to the medium, using the image to which the input/output characteristic is applied at the applying; and outputting a result of the determining. - View Dependent Claims (16, 17, 18, 19, 20)
