Abstract
To provide a technology for preventing, by a simple input operation, a password from being leaked out even if an input operation thereof is peeped by a third party. A plurality of characters different for each input are presented, an input of a processing result about the characters is received, and authentication is made by checking whether or not a result of executing the process as the password stored beforehand on a storage unit about the characters corresponds to the inputted processing result.
