Biometric person authentication method using features extracted from pen holding style

Abstract

The manner of holding a pen is distinctive among people. Therefore, pen holding style is useful for person authentication. In this paper, we propose a biometric person authentication method using features extracted from images of pen holding style. Images of the pen holding style are captured by a camera, and several features are extracted from the captured images. These features are compared with a reference dataset to calculate dissimilarity scores, and these scores are combined for verification using a three-layer perceptron. Preliminary experiments were performed by using a private database. The proposed system yielded an equal error rate (EER) of 2.6%.

Towards pen‐holding hand pose recognition: A new benchmark and a coarse‐to‐fine PHHP recognition network

“…Table 1 tabulates the basic information of our newly established PHHP dataset comparing with the other three hand pose image datasets. Specifically, Pen-holding Style (PHS) [8] is a private database, which consists of only 300 images captured in a single scene, including the same metallic grey background, the same capture view and the same black pen. In addition, these images are mainly used for biometric feature extraction of personal authentication.…”

“…As a sub-branch of 2D hand pose recognition, pen-holding hand pose (PHHP) recognition has attracted increasing research attention in the communities of hand pose recognition in recent years because it has many meaningful practical applications, such as pen-holding hand posture correction [6,9] and userdependent personal authentication [7,8]. For example, in the early years, Cheng et al [7] proposed a video-based PHHP recognition method to identify the writer.…”

Hand Shape Discrimination in Touch Interface toward Personal Authentication on a Tablet Computer

“…Fingerprint authentication can be applied when a mouse is used as an input device, where a fingerprint reader is built into the mouse [3]. In addition, we have previously proposed an authentication method that is based on pen holding style to detect impersonation when examinees use a pen or pen tablet device in an exam [4].…”
