A reference A divides the stored electronic information CA into more than one information element based on a dividing algorithm D (aD) applied with a dividing argument aD, selects information elements from the divided elements and generates a transmittal information block E based on a selecting algorithm S (aS) applied with a selecting argument aS, and sends the transmittal information block E accompanied with the arguments (a D, aS) to an inquirer B, and the inquirer divides the stored electronic information CB into more than one information element and selects a part of the divided elements based on the same dividing and selecting algorithms D (aD) , S (aS) as used by the reference A applied with the arguments (aD, aS), replaces the selected elements with the information elements included in the transmittal information block E so as to form the third electronic information CI, and compares it with the stored electronic information CB to confirm identity between two of the electronic information CA and CB. <IMAGE> |
