Abstract
The process comprises a 'pledging' step in which a debtor party transmits to a creditor party a data item which is the image of a pledged data item, and a 'commencement' step in which the debtor party transmits the plain pledged data item to the creditor party who can verify pledge consistency. In the pledging step, the debtor party produces a seed applied to a pseudo-random generator to produce a pseudo-random word, combines this pseudo-random word in a one-to-one and reversible manner with the pledged data item to produce a checkword, and transmits the checkword to the creditor party. In the commencement step, the debtor party transmits to the creditor party the seed together with the plain pledged data item. The creditor party then applies the seed to a pseudo-random generator similar to that of the debtor party to produce another pseudo-random word, combines in the same one-to-one and reversible manner as for the debtor party, this other pseudo-random word with the checkword, to produce a check data item, and checks the consistency of the check data item with the plain pledged data item received from the debtor party.
