As the mobile handheld devices equipped with fingerprint sensors are produced, it becomes important to protect the private information of a user (i.e., fingerprint image) in the remote applications. In this paper, we consider the possible scenarios to transmit fingerprint images from the handheld device to a server securely using both encryption and watermarking. Moreover, to transmit the large-sized fingerprint images via a restricted bandwidth, the image compression should be considered. Based on the experimental results, we compare and analyze three factors(i.e., the energy consumption, the watermark detection rate, and the fingerprint recognition rate) of the possible compression standard techniques (i.e., the JPEG2000 and the WSQ).
