This paper introduced pPen, a pressure-sensitive digital pen enabled precise pressure and touch input on vision based interactive tabletops. With the help of pPen inputs and feature matching technology, we implemented a novel method supporting multi-user authenticated interaction in the bimanual pen and touch scenario: login can be performed just by stroking one's signature with pPen on the table; a binding between user and pPen was created at the same time, then each interaction command made by pPen is user differentiating. We also conducted laboratory user studies, which later proved the safety and the high resistance to shoulder surfing problem: in the evaluation procedure, any attacker can never log into other user's working space.
