Two Step Authentication System based on OTP & Gesture Recognition Based on Accelerometer

Abstract

Abstract: The paper discusses the use of two step authentication system in- stead of traditional single step such as biometric, password etc. The paper discusses the disadvantages of using existing single layer security in everyday security needs. Further the paper proposes the idea how a Two-step authentication system based on pattern recognition and OTP (One Time Password) would create a more robust and secure authentication system while being cost effective and re- quiring less electronic components. The first layer of security is achieved by pattern recognition by pattern recognition we mean a user draws a pattern in air and using Arduino & ADXL35 (3-axis accelerometer) module we can deduce the pattern .The accelerometer is used to track the X,Y values obtained from the module and using these values we ascertain whether the pattern created by the user is accurate. As for the second layer we use Arduino as a random number generator & SIM7100A (4G SIM module) serves the purposes to send data to the user via SMS.
