Cancelable Iris Biometrics

2012
Cancelable biometrics consist of intentional, repeatable distortions of biometric signals based on transforms which provide a comparison of biometric templates in the transformed domain [418].

Biometric Template Protection Scheme-Cancelable Biometrics

2019
Biometric template is actually digital representation of the biometric features that are extracted by applying different algorithms on the captured images of different types of biometric modalities. This digital information is stored in a biometric database for identification and authentication purposes.

Parameter management schemes for cancelable biometrics

2011 IEEE Workshop on Computational Intelligence in Biometrics and Identity Management (CIBIM), 2011
Protecting biometric information is a critical issue in biometric systems, since physical characteristics such as fingerprints, irises, face and vein patterns, cannot be changed or revoked like passwords. To address this issue, an authentication scheme called cancelable biometrics has been studied, in which the biometric features are transformed by a ...

Cancelable Biometrics Using Noise Embedding

2018 24th International Conference on Pattern Recognition (ICPR), 2018
This paper presents a cancelable biometric (CB) scheme for iris recognition system. The CB approaches are roughly classified into two categories depending on whether the method stresses more on non-invertibility or on discriminability. The former is to use non-invertibly transformed data for the recognition instead of the original, so that the ...

Ensemble-Based Methods for Cancellable Biometrics

2010
In this paper, we investigate the use of genetic algorithms and ensemble systems in cancellable biometrics, using fingerprint-based identification to illustrate the possible benefits accruing. The main aim is to analyze the performance of these well-established structures on transformed biometric data to determine whether they have a positive effect on

Biophasor: Token Supplemented Cancellable Biometrics

2006 9th International Conference on Control, Automation, Robotics and Vision, 2006
Biometrics characteristics are immutable, resulting in permanent biometrics compromise. To address this problem, we prescribe a generic cancellable biometrics formulation - BioPhasor. BioPhasor is a set of binary code based on iterated mixing between the user-specific tokenised pseudo-random number and the biometric feature.

Cancelable Biometrics: A Case Study in Fingerprints

18th International Conference on Pattern Recognition (ICPR'06), 2006
Biometrics offers usability advantages over traditional token and password based authentication schemes, but raises privacy and security concerns. When compromised, credit cards and passwords can be revoked or replaced while biometrics are permanently associated with a user and cannot be replaced.

Cancellable Biometrics for On-line Signature Recognition

2011
With the widespread diffusion of biometrics-based recognition systems, there is an increasing awareness of the risks associated with the use of biometric data. Significant efforts are therefore being dedicated to the design of algorithms and architectures able to secure the biometric characteristics, and to guarantee the necessary privacy to their ...

Cancellable Biometrics and Multispace Random Projections

2006 Conference on Computer Vision and Pattern Recognition Workshop (CVPRW'06), 2006
In this paper, a generic cancellable biometrics formulation is proposed by first transforming the raw biometrics data into a fixed length feature vector, then subsequently re-projecting the feature vector onto a sequence of random subspaces specified by the tokenised random vectors.
