Title: Information concealing system, device, and method
Inventor: KOMATA YUSUKE
IPC: G06F17/21
Filed: 2008-02-21
Abstract: <P>PROBLEM TO BE SOLVED: To create a concealed text wherein the fact that secret information is concealed is prevented from being discovered.  <P>SOLUTION: When the concealed text is created, a transmitting side information concealing device converts, in a character string of a cover text, ASCII characters (search character string C for replacement) inserted between the characters relevant to secret information into a half-width character string C, and converts ASCII characters (search character string C for non-replacement) inserted between the characters irrelevant to secret information into a full-width character string. That is, the transmitting side information concealing device suppresses the modification of the cover text to the minimum through the conversion between the half-size characters and full-size characters, so that no trace of concealing the secret information can be found. Thus, in the information concealing system, a concealed text can be created wherein the fact that secret information is concealed is prevented from being discovered.  <P>COPYRIGHT: (C)2009,JPO&INPIT
