Abstract: A huge number of users are using smart phones to communicate with each other. A smart phone user is exposed to various threats when they use their phone for communication. These threats can disorganization the operation of the smart phone, and transmit or modify user data rather than original. So applications must guarantee privacy and integrity of the information. Single touch mobile security is unable to give efficient performance for confidential data. Hence we are moving towards multitouch mobile security for high security. In computing, multi-touch is authentication technology that enables a surface to recognize the presence of more than one touch points of contact with the touch screen . By using multiple touch points to authenticate user for access confidential data in mobile phones. we are presenting our study about biometric gestures to authenticate user through multitouch finger points for more security.
