An advertising and shopping contest whereby a contestant ( 1 ) enters a valid designated character string from an advertisement ( 10 ) and a valid designated character string from a sales transaction record ( 20 ) into a preset algorithm ( 40 ). The preset algorithm ( 40 ) processes the information supplied by the contestant ( 1 ) and derives a new character string ( 50 ). If the new character string ( 50 ) matches ( 80 ) the pre-selected winning character string ( 60 ), the contestant ( 1 ) is deemed a winner ( 100 ), otherwise the contestant is not a winner ( 90 ). However, in order to receive a reward, it will be necessary to authenticate the character strings ( 110 ) the winner ( 100 ) entered, as being genuine ( 110 ), to prevent fraud. If they are genuine ( 120 ), then a reward is granted ( 130 ). If said character strings are not genuine, the contestant is not a winner ( 90 ).
