Abstract (in Japanese) (See Japanese page) 
(in English) Nowadays passwords information could be stolen by shoulder-surfing attack with peeping and/or remote video camera etc. Challenge & Response authentication could be an effective measure to resist the shoulder-surfing attack. However, Challenge and Response authentication need to generate a secure response with the cryptographic functions, which is burden for users. Then Sasamoto et. al. proposed to transmit the challenge as the tactile information. Their scheme can hide the challenge to generate the response from attackers. Hence, it is expected that the security level is maintained even with a simple response generation. However, their scheme can transmit only limited information in the challenge channel. So the scheme is vulnerable against brute force attack. Jn this paper, therefore, we proposed to strengthen the tactile information to solve the problem.
