The evaluation was carried under both the verification and the identification scenarios in an effort to show the effect of missing data estimation on the relatively understudied multi-biometric identification scenario. Evaluation was performed on the Biosecure DS2 score database and satisfying performance was achieved under both biometric scenarios.","PeriodicalId":409073,"journal":{"name":"2013 IEEE Workshop on Biometric Measurements and Systems for Security and Medical Applications","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129501015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a novel framework for fusion at hybrid rank-score level based on graph models where an additional information concerning the non-matched scores is exploited.

In particular, we rely on the Weber Local Descriptor (WLD), which is a powerful and robust descriptor recently proposed for texture classification. Inspired by Weber's law, it consists of two components, differential excitation and orientation, evaluated for each pixel of the image. Joint histograms of these components are then processed to build the discriminative features used to train a linear kernel SVM classifier. Experimental results with different databases and different sensors show WLD to perform favorably compared to the state-of-the-art methods in fingerprint liveness detection. In addition, by combining WLD with LPQ (Local Phase Quantization) results further improve significantly.","PeriodicalId":409073,"journal":{"name":"2013 IEEE Workshop on Biometric Measurements and Systems for Security and Medical Applications","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130540493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even though there are methods to create images of artificial irises, there is no method exclusively focused in the synthesis of the iris biometric signatures (IrisCodes). In experiments related with some phases of the biometric recognition process (e.g., indexing / retrieval), a large number of signatures is required for proper evaluation, which, in case of real data, is extremely hard to obtain. Hence, this paper describes a stochastic method to synthesize IrisCodes, based on the notion of data correlation. These artificial signatures can be used to feed experiments on iris recognition, namely on the iris matching, indexing and retrieval phases. We experimentally confirmed that both the genuine and impostor distributions obtained on the artificial data closely resemble the values obtained in data sets of real irises. Finally, another interesting feature is that the method is easily parametrized to mimic IrisCodes extracted from data of varying levels of quality, i.e., ranging from data acquired in high controlled to unconstrained environments.","PeriodicalId":409073,"journal":{"name":"2013 IEEE Workshop on Biometric Measurements and Systems for Security and Medical Applications","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115177733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present a new windowing technique for feature point validation in order to improve the accuracy of retinal vascular pattern recognition. The proposed method applies a windowing technique on skeleton vascular pattern to eliminate false feature points which appear due to vessel breakages, short vessels and spurs. The testing of the proposed methodology is performed using two retinal image databases i.e. VARIA and RIDB.

This has spurred the interest, from one side, in exploiting their apparent vulnerabilities, and on the other side, in protecting users from any malfeasance. In this scenario, it has become essential to develop and deploy secure access and identification protocols on mobile platforms. Another emerging aspect that also needs attention bears on the commercial and social use of identity management systems. Towards such ends, this paper proposes using biometrics as the technology of choice, and describes FAME (Face Authentication for Mobile Encounters). FAME is an embedded application for mobile devices that provides both verification and identification, including identity management to support social activities, e.g., finding doubles in a social network. Such functionalities are implemented subject to privacy and security concerns. FAME cascade architecture is modular. The single modules perform image acquisition, anti-spoofing, face detection, face segmentation, feature extraction, and face matching. FAME also provides continuous recognition and best biometric sample selection, that both accommodate varying pose and illumination. All procedures are optimized for mobile use, using low-demanding and computation-light algorithms. Preliminary questionnaires administered to users engaged with using FAME show user acceptance, ease of use, and reliability.","PeriodicalId":409073,"journal":{"name":"2013 IEEE Workshop on Biometric Measurements and Systems for Security and Medical Applications","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127733085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach utilizes temporal and spectral information to characterize ECG waveform morphology and timing with low computational cost. To demonstrate the effectiveness of this approach, records from the MIT-BIH normal sinus rhythm database are used to test subject identification, yielding high accuracy and positive predictive value.","PeriodicalId":409073,"journal":{"name":"2013 IEEE Workshop on Biometric Measurements and Systems for Security and Medical Applications","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124474073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
