PROBLEM TO BE SOLVED: To allow even a small amount of a storage resource and calculation resource to be enough for the purpose by collating consistency with data items of security stage for granted data items. SOLUTION: Concerned parties A, B with the processing have two generators is operation according to the same algorithm such as pseudo random number generators names PKG. A debt party A has also a random number generator G. The concerned particles A, B have a means executing exclusive OR function bit by bit each. Finally the debt party B ha a comparator means C one by one bit to determine the identity between two words received as inputs. Then in the mode of transmission to the debt party (or recipient) A, the debt party (or recipient) A being a possessor of granted data items exchanges information with the debt party B. Moreover, the debt party A exchanges information with the debt party B and the debt party B collates the consistency with the data items in the security stage of the granted data items.
