In order to provide remote user authentication services with handheld devices equipped with fingerprint sensors, both energy efficiency and confidentiality/privacy requirements should be satisfied. However, nothing is known about the collective performance of fingerprint verification and secure transmission protocol in remote applications. In this paper, we consider the possible scenarios of an application to securely transmit fingerprint images from a handheld device to a server. It uses both encryption and watermarking and ensures efficiency using compression standards(i.e., WSQ and JPEG2000). Based on the evaluation, the compression scenario using WSQcan reduce the total energy consumption of the no-compression scenario by 33% without significant degradation of the fingerprint recognition rate or watermarking detection rate.
