<p><P>PROBLEM TO BE SOLVED: To provide a source code capable of concealing the program content on a source level, requiring no special adjustment, and capable of hiding a source program even on an object level only by compiling the program. <P>SOLUTION: A source program converting tool 511 substitutes an initializing part of constant data included in the source code S1 with an initializing part of substitute constant data converted into a decoding difficult state by reversible conversion processing, and forms the source code S2 of inserting a source of inverse conversion processing for restoring original constant data from the substitute constant data into a place before referring to the constant data. <P>COPYRIGHT: (C)2004,JPO</p> |
