Information hiding system, method, and printed matter into which information is hidden
First Claim
1. An information hiding system for hiding information data within printing data disposed upon a printable media, said system comprising:
- embedding means for embedding said information data within said printing data, wherein said embedding means comprises an embedding computer upon which is stored an embedding program means for performing the steps of;
fetching a digital image represented by pure binary code;
decomposing said digital image into a set of bit-planes;
replacing complex local portions of at least one of said bit-planes with said information data;
composing said bit planes into an embedded image represented by pure binary code; and
sending said embedded image to said printing means for printing onto said printable media;
printing means for disposing said information data and said printing data upon said printable media to form a printed matter;
extracting means for reading said printed matter and extracting said information data from said printing data; and
outputting means for outputting said information data from said extracting means.

Abstract
An information hiding system that hides information-data in the printing-data according to steganography using an embedding means, and produces printed matter by printing out the printing-data on printable media. A scanner is used to read the data, such as image or pattern data, from the printed matter in order to restore the printing-data. The hidden information-data is then extracted from the restored printing-data using an information-data extracting means. Finally, the information-data is outputted in such a form as an image, musical or voice sound, and/or character letters according to the outputting means.

9. A method for hiding and extracting information data from printing data disposed upon printed matter comprising the steps of;
-
embedding said information data within said printing data, wherein said embedding step comprises the steps of; fetching a digital image represented by pure binary code; decomposing said digital image into a set of bit-planes; replacing complex local portions of at least one of said bit-planes with said information data; composing said bit planes into an embedded image represented by pure binary code; and sending said embedded image to said printing means for printing onto said printable media; disposing said information data and said printing data upon a printable media to form said printed matter; reading said printed matter; extracting said information data from said printing data; and outputting said information data extracted in said extracting step. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An information hiding system for hiding information data within printing data disposed upon a printable media, said system comprising:
-
embedding means for embedding said information data within said printing data; printing means for disposing said information data and said printing data upon said printable media to form a printed matter; extracting means for reading said printed matter and extracting said information data from said printing data; and outputting means for outputting said information data from said extracting means; wherein said extracting means comprises a scanner and an extracting computer comprising a monitor and upon which is stored an extracting program means for; scanning said printed matter such that it is converted into numerical data; inputting a key into said computer; representing said numeral data as pure binary code; decomposing said numerical data into a set of binary images; extracting said information data from at least one of said decomposed binary images; and displaying said information data on said monitor. - View Dependent Claims (17, 18)
