Abstract
In the government forensic department, the need to crack the authentication system of the electronic gadgets or personal devices of criminals and victims has been tremendously increased in the recent years as biometrics plays a major role of authentication. A number of consumer electronic devices, such as smartphones, are beginning to incorporate fingerprint sensors for user authentication. The MasterPrint is a technique where there is a possibility of generating a synthetic or real partial fingerprint that matches one or more template that is stored in the database for a significant number of users Thereby this methodology used by the government and forensic sector to break through the authentication of the device to retrieve the crucial data stored and to access the system. This methodology implied is used to more efficiently to launch indirect attack against fingerprint based authentication system. The algorithm thus used results in increase of efficient MasterPrints with maximum matching rate in comparison to the outcome of the present techniques.
