PROBLEM TO BE SOLVED: To provide a data security system by which the contents of the information of a computer are not made cognoscible even by a person who processes the information. SOLUTION: In the case that information contens are not cognoscible when asking the person who processe the information for the data processing of a computer with secrecy, the code is transformed into a pseudo code or numerical data are transformed into pseudo data (code or the like) different from the correct data by multiplying or diving the data by an arbitrary coefficient, and the information is transferred to the person who processes the information, so that the secrecy of the data can be protected. At the client side who receives the data as the result of the information processing, the pseudo data are decoded (inversely transformed) into the original correct data (code or the like) and utilized for job. |
