The PIN based single level authorization of Mobile Payment System suffers several security leakage problems. Integrating biometric identifier as one more level of authorization increases the robustness of the payment system. But as mobile device and wireless network has certain constraint, so it is not possible to use any biometric identifier for authentication. This paper presents a comparativ...
This paper attempts to present current state in the area of user localization in cellular networks and shows custom solution for positioning using pocket computer and fingerprint method also known as fingerprinting. It operates in Global System for Mobile communications (GSM) network, although fingerprinting is also applicable in other wireless networks, such as Universal Mobile Telecommunicati...
This paper proposes a novel indoor Wireless Local Area Network (WLAN) positioning algorithm by using the Support Vector Machine (SVM) Hyperplane Margin Clustering and Regression (SVMCR). First of all, we rely on the SVM Hyperplane Margin Clustering (SVMC) to reduce the search space of the fingerprint database. Second, we use the Support Vector Regression (SVR) to characterize the relations of t...
Passports issued nowadays have an embedded RFID chip that carries digitally signed biometric information. Access to this chip is wireless, which introduces a security risk, in that an attacker could access a person’s passport without the owner knowing. While there are measures in place to prevent unauthorised access to the data in the passport, we show that it is easy to remotely detect the pre...
FeiYangchangweiyan capsule (FY capsule), a traditional Chinese medicinal preparation consisting of three medicinal herbs, has been used to treat bacterial dysentery, acute, and chronic gastroenteritis for several decades. In this study, a novel, convenient, accurate, and valid method was developed by using high-performance liquid chromatography (HPLC) coupled with diode array detection...
Conventional algorithms for fingerprint recognition are mainly based on minutiae information. However, the small number of minutiae in partial fingerprints is still a challenge in fingerprint matching. In fingerprint recognition systems, there are frequently appeared partial fingerprints, such as incompletely touching in fingerprint scanning or latent fingerprints. In this paper, we studied the...
A robust radio map is essential in implementing a fingerprint-based indoor positioning system (IPS). However, the offline site survey to manually construct time-consuming and labour-intensive. Various interpolation techniques have been proposed infer virtual fingerprints reduce time effort required for surveys. This paper presents novel fingerprint interpolator using multi-path loss model (M-PL...
Fingerprint identification system is mainly consisted of fingerprint achieving, fingerprint classification and fingerprint matching. Fingerprint matching is the key to the system and effects on the precision and efficiency of the whole system directly. Fingerprints are matched mainly based on their fingerprint texture pattern which can be described with the orientation field of fingerprints. A ...
Fingerprint identification is divided into fingerprint pretreatment, fingerprint feature extract ion and a fingerprint match. Based on embedded technology and fingerprints processing algorithms, embedded automatic fingerprint identification system fingerprint identification of various processes study the algorithm, this paper expounds the characteristics of various algorithm with using details.
Fingerprint ridge frequency is a global feature, which is most prominently different in fingerprints of men and woman, and it also changes within the maturing period of a person. This paper proposes the method of fingerprint pre-classification, based on the ridge frequency replacement by the density of edge points of the ridge boundary. This method is to be used after applying the common steps ...
