A Survey Paper on Palm Prints Based Biometric Authentication System

In this paper we are providing an approach for authentication using palm prints. Reliability in computer aided personal authentication is becoming increasingly important in the information-based world, for effective security system. Biometrics is physiological characteristics of human beings, unique for every individual that are usually time invariant and easy to acquire. Palm print is one of the relatively new physiological biometrics due to its stable and unique characteristics. The rich information of palm print offers one of the powerful means in personal recognition

Multispectral Palmprint Encoding and Recognition

Palmprints are emerging as a new entity in multi-modal biometrics for human identification and verification. Multispectral palmprint images captured in the visible and infrared spectrum not only contain the wrinkles and ridge structure of a palm, but also the underlying pattern of veins; making them a highly discriminating biometric identifier. In this paper, we propose a feature encoding scheme for robust and highly accurate representation and matching of multispectral palmprints. To facilitate compact storage of the feature, we design a binary hash table structure that allows for efficient matching in large databases. Comprehensive experiments for both identification and verification scenarios are performed on two public datasets -- one captured with a contact-based sensor (PolyU dataset), and the other with a contact-free sensor (CASIA dataset). Recognition results in various experimental setups show that the proposed method consistently outperforms existing state-of-the-art methods. Error rates achieved by our method (0.003% on PolyU and 0.2% on CASIA) are the lowest reported in literature on both dataset and clearly indicate the viability of palmprint as a reliable and promising biometric. All source codes are publicly available.Comment: Preliminary version of this manuscript was published in ICCV 2011. Z. Khan A. Mian and Y.

Fourier spectral of PalmCode as descriptor for palmprint recognition

Study on automatic person recognition by palmprint is currently a hot topic. In this paper, we propose a novel palmprint recognition method by transforming the typical palmprint phase code feature into its Fourier frequency domain. The resulting real-valued Fourier spectral features are further processed by horizontal and vertical 2DPCA method, which proves highly efficient in terms of computational complexity, storage requirement and recognition accuracy. This paper also gives a contrast study on palm code and competitive code under the proposed feature extraction framework. Besides, experimental results on the Hongkong PolyU Palmprint database demonstrate that the proposed method outperforms many currently reported local Gabor pattern approaches for palmprint recognition

Secure Authentication for Mobile Users

RÉSUMÉ :L’authentification biométrique telle que les empreintes digitales et la biométrie faciale a changé la principale méthode d’authentification sur les appareils mobiles. Les gens inscrivent facilement leurs modèles d’empreintes digitales ou de visage dans différents systèmes d’authentification pour profiter de leur accès facile au smartphone sans avoir besoin de se souvenir et de saisir les codes PIN/mots de passe conventionnels. Cependant, ils ne sont pas conscients du fait qu’ils stockent leurs caractéristiques physiologiques ou comportementales durables sur des plates-formes non sécurisées (c’est-à-dire sur des téléphones mobiles ou sur un stockage en nuage), menaçant la confidentialité de leurs modèles biométriques et de leurs identités. Par conséquent, un schéma d’authentification est nécessaire pour préserver la confidentialité des modèles biométriques des utilisateurs et les authentifier en toute sécurité sans compter sur des plates-formes non sécurisées et non fiables.La plupart des études ont envisagé des approches logicielles pour concevoir un système d’authentification sécurisé. Cependant, ces approches ont montré des limites dans les systèmes d’authentification sécurisés. Principalement, ils souffrent d’une faible précision de vérification, en raison des transformations du gabarit (cancelable biometrics), de la fuite d’informations (fuzzy commitment schemes) ou de la réponse de vérification non en temps réel, en raison des calculs coûteux (homomorphic encryption).---------- ABSTRACT: Biometric authentication such as fingerprint and face biometrics has changed the main authentication method on mobile devices. People easily enroll their fingerprint or face template on different authentication systems to take advantage of their easy access to the smartphone with no need to remember and enter the conventional PINs/passwords. However, they are not aware that they store their long-lasting physiological or behavioral characteristics on insecure platforms (i.e., on mobile phones or on cloud storage), threatening the privacy of their biometric templates and their identities. Therefore, an authentication scheme is required to preserve the privacy of users’ biometric templates and securely authenticate them without relying on insecure and untrustworthy platforms. Most studies have considered software-based approaches to design a privacy-reserving authentication system. However, these approaches have shown limitations in secure authentication systems. Mainly, they suffer from low verification accuracy, due to the template transformations (in cancelable biometrics), information leakage (in fuzzy commitment schemes), or non real-time verification response, due to the expensive computations (in homomorphic encryption)

Performance comparison of intrusion detection systems and application of machine learning to Snort system

This study investigates the performance of two open source intrusion detection systems (IDSs) namely Snort and Suricata for accurately detecting the malicious traffic on computer networks. Snort and Suricata were installed on two different but identical computers and the performance was evaluated at 10 Gbps network speed. It was noted that Suricata could process a higher speed of network traffic than Snort with lower packet drop rate but it consumed higher computational resources. Snort had higher detection accuracy and was thus selected for further experiments. It was observed that the Snort triggered a high rate of false positive alarms. To solve this problem a Snort adaptive plug-in was developed. To select the best performing algorithm for Snort adaptive plug-in, an empirical study was carried out with different learning algorithms and Support Vector Machine (SVM) was selected. A hybrid version of SVM and Fuzzy logic produced a better detection accuracy. But the best result was achieved using an optimised SVM with firefly algorithm with FPR (false positive rate) as 8.6% and FNR (false negative rate) as 2.2%, which is a good result. The novelty of this work is the performance comparison of two IDSs at 10 Gbps and the application of hybrid and optimised machine learning algorithms to Snort

A Survey on Biometrics and Cancelable Biometrics Systems

Now-a-days, biometric systems have replaced the password or token based authentication system in many fields to improve the security level. However, biometric system is also vulnerable to security threats. Unlike password based system, biometric templates cannot be replaced if lost or compromised. To deal with the issue of the compromised biometric template, template protection schemes evolved to make it possible to replace the biometric template. Cancelable biometric is such a template protection scheme that replaces a biometric template when the stored template is stolen or lost. It is a feature domain transformation where a distorted version of a biometric template is generated and matched in the transformed domain. This paper presents a review on the state-of-the-art and analysis of different existing methods of biometric based authentication system and cancelable biometric systems along with an elaborate focus on cancelable biometrics in order to show its advantages over the standard biometric systems through some generalized standards and guidelines acquired from the literature. We also proposed a highly secure method for cancelable biometrics using a non-invertible function based on Discrete Cosine Transformation (DCT) and Huffman encoding. We tested and evaluated the proposed novel method for 50 users and achieved good results

Binary palmprint representation for feature template protection

The major challenge of biometric template protection comes from the intraclass variations of biometric data. The helper data scheme aims to solve this problem by employing the Error Correction Codes (ECC). However, many reported biometric binary features from the same user reach bit error rate (BER) as high as 40%, which exceeds the error correcting capability of most ECC (less than 25%). Therefore, a novel palmprint binary feature extraction method is proposed in this paper. The real-valued features are firstly extracted. Then one-bit quantization and reliable bits selection are processed. For verification multiple samples are required to be enrolled while training is not necessary. Experiments have been carried out on the HongKong PolyU Palmprint database. Results show that our method achieves much lower BER, lower verification error rate and allows a secret key long enough for security
