Title: Method, system and product for introducing improvement of confidentiality in symbol system with error correcting function
Inventor: TAKAHASHI SHIGENORI
IPC: G06K19/06
Filed: 2007-01-31
Abstract: <P>PROBLEM TO BE SOLVED: To solve problems in a symbol system with an error correcting function, wherein redundant added information for error correction is included in encoding data to permit correct encoding within the tolerance of the system even if symbols serving as encoded data are partially modified and lacking, which results in acquiring resistance to fouling and easy recognition, but no consideration is given to confidentiality of data, and a considerable management and storage method is required for independent information required for the structure such as encryption key information to generally improve confidentiality of information.  <P>SOLUTION: Independent information is usable as modification information of symbols if an amount is within a range not disturbing the error correcting function and a location is on the symbol. When the independent information is encoded, on the other hand, a portion coinciding with the encoded state before modification emerges. The amount and location of the independent information are thereby difficult for a third person to specify. As a result, confidentiality of the independent information can also be guaranteed.  <P>COPYRIGHT: (C)2008,JPO&INPIT
