Following the Waldo proof, there is recent work showing how to convince someone that you have solved a Sudoku puzzle without revealing the solution (this is a recent paper by Gradwohl, Naor, Rothblum and myself). The paper describes cryptographic and *physical* protocols for this task, accompanied by rigorous definitions and analysis. The paper and a demo are available at http://www.wisdom.weizmann.ac.il/~naor/PAPERS/sudoku_abs.html
