There were many attempts to develop plausible face template protection schemes that can satisfy four design criteria of biometric template protection, namely non-invertibility, cancellability, non-linkability and performance. In this paper, a cancellable face template scheme, namely random permutation maxout (RPM) transform is proposed. The RPM transforms a real-valued face feature vector (template) into a discrete index code as a means of protected form of face template. Such a transform offers two major merits: 1) robustness to noises in numeric values of original face template; and 2) nonlinear embedding based on the implicit order of the data. The former promotes accuracy performance preservation while the latter offers strong non-invertible transformation that leads to hardness in inversion attack. Several experiments based on the AR face database are conducted to observe the RPM transform performance with respect to its various parameters. The analyses justify its resilience to inversion attack as well as satisfy the revocability and non-linkability criteria of cancellable biometrics.","PeriodicalId":262849,"journal":{"name":"International Conference on Biometrics Engineering and Application","volume":"182 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129295688","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}

However, vanilla RCM breaks down in face recognition due to its inadequacy in extracting discriminative features from facial image. In this paper, cascaded Principle Component Analysis (PCA) filter responses that derived from the multi-layer PCA network are leveraged to extract the sufficient discriminative facial feature for RCM construction. The factors that affect the performance of cascaded PCA filter responses in forming RCM for 2.5D face recognition is investigated. To be specific, the influence of patch size and filter numbers of cascaded PCA filter responses to RCM is probed. Besides that, block division is proposed for RCM to further enhance the accuracy performance. Experimental results have demonstrated the efficacy of the proposed approach.","PeriodicalId":262849,"journal":{"name":"International Conference on Biometrics Engineering and Application","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116756217","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}
