“…In order to abolish credential-based authentication, biometrics are increasingly applied for authentication purposes in a broad variety of commercial (e.g., fingerprint door locks) and institutional applications (e.g., border control). Therefore, biometric authentication requires more stringent techniques to identify registered subjects [208]. Besides the fact that subjects share biometric traits rather reluctantly, the common use of biometrics is often considered as a threat to privacy [209].…”

Form a privacy perspective most concerns against the common use of biometrics arise from the storage and misuse of biometric data. Biometric cryptosystems and cancelable biometrics represent emerging technologies of biometric template protection addressing these concerns and improving public confidence and acceptance of biometrics. In addition, biometric cryptosystems provide mechanisms for biometric-dependent key-release. In the last years a significant amount of approaches to both technologies have been published. A comprehensive survey of biometric cryptosystems and cancelable biometrics is presented. State-of-the-art approaches are reviewed based on which an in-depth discussion and an outlook to future prospects are given.

By now, biometric systems find already home in a broad range of commercial and institutional applications. They are typically employed to authenticate users before allowing access to restricted areas or services. The interest in biometrics is mainly due to their potential advantages over traditional authentication procedures. Such advantages extend across: security, accuracy, reliability, usability, and friendliness. Unfortunately, with the benefits also possible risks arise. A main concern in the design of biometric authentication systems is the protection of the biometric templates. In fact, potential threats to users' privacy might derive from the abuse of biometric information. These privacy concerns are the subject of current discussions and often prevent the adoption of biometric systems on a large scale. The aim of this paper is to present the latest advances in the area of biometric authentication systems comprising the construction of biometric templates from actual samples. The discussion will cover research results published in the open literature and patents recently filed with inventions related to the field.

“…With the successful deployment of larger-scale iris recognition systems at the airports and hospitals [2], many concerns have been raised. Biometric applications are often considered unsecure due to the misuse of biometric data and identity management [3]. This concern is acceptable, as the compromised biometric traits will become useless in all the involved biometric applications.…”

A New Design for Alignment-Free Chaffed Cancelable Iris Key Binding Scheme

et al. 2019

Iris has been found to be unique and consistent over time despite its random nature. Unprotected biometric (iris) template raises concerns in security and privacy, as numerous large-scale iris recognition projects have been deployed worldwide—for instance, susceptibility to attacks, cumbersome renewability, and cross-matching. Template protection schemes from biometric cryptosystems and cancelable biometrics are expected to restore the confidence in biometrics regarding data privacy, given the great advancement in recent years. However, a majority of the biometric template protection schemes have uncertainties in guaranteeing criteria such as unlinkability, irreversibility, and revocability, while maintaining significant performance. Fuzzy commitment, a theoretically secure biometric key binding scheme, is vulnerable due to the inherent dependency of the biometric features and its reliance on error correction code (ECC). In this paper, an alignment-free and cancelable iris key binding scheme without ECC is proposed. The proposed system protects the binary biometric data, i.e., IrisCodes, from security and privacy attacks through a strong and size varying non-invertible cancelable transform. The proposed scheme provides flexibility in system storage and authentication speed via controllable hashed code length. We also proposed a fast key regeneration without either re-enrollment or constant storage of seeds. The experimental results and security analysis show the validity of the proposed scheme.
