Abstract
Recently, number of mobile users and mobile banking applications are increased dramatically. The current mobile banking system unable to provide face-to-face transaction, that is, anyone can perform transaction by using proper secret code. This study proposes a new triangular based indexing method to authenticate the original account holder in mobile banking environment. A Delaunay triangulation indexing scheme has been designed for protecting biometric template and Voronoi vertex is calculated for verifying the authorised person. A novel algorithm has been developed for mutual authentication. To reduce key size, elliptic curve cryptography technique is adapted. Biometric key is generated for secure communication and also discusses the security aspects of the proposed method.
