In this paper, we propose a new online palmprint verification method, providing a more convenient way to users when having palmprint images captured. Unlike other palmprint verification methods, which use positioning pods to fix the location of a palm, we suggest capturing a palmprint without using any devices to locate the palm. Therefore it makes the users more comfortable but requires better positioning algorithm to locate the palmprint automatically. Here we propose an inscribe circle based palmprint positioning and interesting area extraction algorithm to deal with the palmprint position variation introduced in capturing. We also suggest using the histogram stretching to eliminate the impact of environment light variation. We suggest using the Niblack method to extract the principle lines on a palm and proposed a bi-directional matching method for similarity measurement. The experimental results demonstrate the effectiveness of our method.
