Abstract


Currently, graphical password methods are available for android and other devices, but the major problem is vulnerability issue. A map graphical-based authentication system (Dheeraj et al, 2013) was designed on mobile android devices, but it did not provide a large choice or multiple sequence to user for selecting password which made it vulnerable to brute-force attack, and there is no randomization which made it prone to shoulder-surfing attack. This proposed system seeks to improve the map graphical-based password authentication system android application devices. The system adds the password space size, rule and randomization during registration and login stage. This will improve the system and make it more secured against brute force and shoulder surfing attacks. The experimental results revealed that 910 trials instead of 730 using two countries selection, 5760 trials instead of 5050 for the existing system are available on the map using 3 countries, 352807 trials instead of 30250 for the existing system are available on the map using 4 countries and 181440 trials instead of 151210 for the existing system are available on the map using 5 countries. Thus, very larger number of trials has to be done for detection to succeed using brute force technique.
