Smart Authentication Using Graphical Password for Android Devices

Abstract

Information has become the oxygen of the modern world. To keep information protected from the so-called ‘nefarious people’ we need security. There are multiple authentication systems for security like text-based, pin, biometrics, graphical, etc. However, the drawbacks of these are that the user tends to keep passwords, which are fairly easy to remember, and such passwords can thus be easily cracked. This paper mainly focuses on the picture password authentication system, which is an upcoming alternative authentication system. According to research, humans tend to recollect images better than text, this system promotes the user to select a password which is difficult to guess but at the same time, can be easily remembered. This paper also focuses on overcoming some drawbacks of Persuasive Cued Click Points (PCCP) , along with making the system more secure. The proposed system makes use of five images and captures one section from each of the selected images. For successful login, the users simply have to select the same sections on every image as decided earlier. Thus, users can be authenticated without having to input even a single character. To avoid brute force and any other bypass techniques, the users are allowed only three consecutive failed attempts. Upon failing those, the user account will be locked, and can be unlocked only after answering the registered security questions.
