Providing Security using Touch Screen Pattern

Touch screen based system allows an easy navigation around a GUI based environment. As the knowledge advances, people may be able to operate computers without mice and keyboard. Number of peoples uses touch screen mobile phones, tablets, PDA's for the different purposes such as accessing online data, net banking, storing personal data [bank account details, contact numbers , official data etc] . If such mobile is lost or taken then it can be misuse by other peoples and also there is problem for recovering such the data. Hence providing security for such Smartphone devices, we are survey the techniques which provide safety to the Smartphone devices. To put off this type of activities and offer security for the field of computer science. In this paper, I recommend and provide an idea for uniqueness of the secret word using implicit authentication approach that enhanced the password pattern with additional security layer .I provide two security checks in two steps. The two authentication methods used are time taken to draw the pattern which is a behavioural biometric authentication method, password pattern .If two methods are satisfy then only the user allow to access.
