To prevent shoulder surfing attack, a secured channel between the device and user must be established so that it cannot be eavesdropped by an adversary. In this paper we have explored vibration signals to design authentication services namely - (a) VDLS and (b) M-VDLS to resist shoulder surfing attack. The use of vibration provides a key strength to bypass the threat of shoulder surfing without using any auxiliary device. Thus, proposed schemes in this paper avail aforementioned advantage to address the attack. While VDLS attains very high security standard compared to existing approaches, M-VDLS ensures high usability standard to avoid the attack in mobile environment. Both these approaches are also capable of providing solution against classical shoulder surfing attack without any information leakage. Finally, we show that required overheads of proposed approaches are reasonable in practice and outperform the existing approaches in terms of security and usability.
