Preventing Password Reuse

Utterly secure. Most of the systems today rely on static passwords to verify the user’s identity. This paper describes a method of implementing two factor authentication using mobile phones. The proposed system involves using a mobile phone as a software token for One Time Password generation. OTP algorithm powered with user’s unique identifications like International Mobile Equipment Identification and Subscriber Identification Module; makes a finite alphanumeric token valid for a session and for a single valid for only a short user defined period of time and is generated by factors that are unique to both, the user and the mobile device itself. Additionally, an SMS retrieving the password and as a possible mean of synchronization.
