Advertising and shopping contest

Abstract

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).
