The purpose of a one-time password (OTP) is to make it more difficult to gain unauthorized access to restricted resources, like a computer account. Traditionally static passwords can more easily be accessed by an unauthorized intruder given enough attempts and time. By constantly altering the password, as is done with a one-time password, this risk can be greatly reduced. In this paper, we propose the new noisy password technique. The proposed system attempts to alleviate the problem of shoulder surfing or eves dropping by making the replay of a password useless. Every time a user is authenticated by totally different password. The noisy password constitute of several parts, the actual password and additional noisy parts that are well studied to generate different passwords almost every time a user wants to authenticate himself. The noisy parts are proven to be robust against any hacking attacks. Experimental results give good indication of the ease of utilization of the new system with low error rates that can be enhanced by time.
