As for each data item, one or the part above that as for the possessing and the entire part the complete data set is formed. Each part of the data set has the water mark which possesses the identifier of the part of that and the identifier of the data set. With ideal execution example, as for the identifier of the part of that it is address of the part of that, the identifier of the data set is serial number and the indicator of entire size of the data set. Existence of the data set whether the original part which forms the data set exists is verified by checking the water mark of the part which is selected to random in order to verify. There is no part that or it was modified, when it is discovered, processing after the data item of the data set is prevented. With ideal execution example, the identifier is accumulated as forcing and combining the brittle water mark.
