Assessment of vulnerabilities of the biometric template protection mechanism
International Journal of Advanced Technology and Engineering Exploration
In the ever-changing world of global data transmission, the security of data and individual privacy are the growing fears in today's human life worldwide. The major concerns are the protection of the biometric templates in the biometric identification and authentication process. Storage of the biometric template in the database raises the chance of compromising it, hence lead to serious threats and abuse of the person's identity. When an individual's registered biometric data is disclosed, their security and privacy can be compromised. Therefore, public acceptance of biometrics will depend on the system designer's ability to demonstrate that the systems are robust, with low error rates, and tamper proof. If someone's biometric template inside the database is compromised, that consequently might imply identification robbery of that individual. In the recent past, a considerable number of methods for biometric template protection have been published. This article explains, a thorough valuation on numerous attacks and threats associated with the biometric system alongside the biometric template protection, elucidating the measures anticipated to address the threats, to the performance gap and establish the status quo of the current biometric template protection for public acceptance.
A Survey on Biometric Template Protection
Biometric authentication offers most reliable approach to person authentication. This authentication approach is based on the "what you are" security measure. However, biometric templates are vulnerable to different types of attacks and any data leakage cause privacy risks. Unlike passwords, stolen biometric data cannot be revoked or reissued hence biometric templates must be protected and any leakage of biometric information must be prevented. This paper surveys various biometric template protection schemes.
Biometric template security: Challenges and solutions
2005
ABSTRACT A biometric system is vulnerable to a variety of attacks aimed at undermining the integrity of the authentication process. These attacks are intended to either circumvent the security afforded by the system or to deter the normal functioning of the system. We describe the various threats that can be encountered by a biometric system. We specifically focus on attacks designed to elicit information about the original biometric data of an individual from the stored template.
Securing the Biometric template: A Survey
Authentication is considered as the most important security goal that demands attention. Many methods such as the use of passwords, smart cards, passcodes, biometrics etc. have been under use as authenticators. However of all these techniques biometrics are proved to be the best techniques of the all. Many organizations around the globe have deployed systems that make use of biometrics as authenticators. However, the main concern about such systems is the security of the biometric template that is stored in the database within the same system along with many other templates. The compromise of a biometric template is irreversible which is why it is of utmost importance that these templates are made secure. Many techniques and methods have already been proposed by researchers around the world to secure such templates. As everything comes with its pros and cons, this paper provides a critical overview of these techniques.
A Review on Biometric Template Security
2018
With the rapid increase in number of biometric recognition systems, an attacker‘s benefit in staging a system compromise is also increasing and thus is the need to ensure system security and reliability. This dissertation grants a thorough analysis of the vulnerabilities of a biometric recognition system with emphasis on the vulnerabilities related to the information stored in biometric systems in the form of biometric templates. To encourage the improvement of techniques to protect biometric templates, we show the use of biometric cryptography in the existing systems. While biometric cryptosystems permit binding a secure key to the biometric data to obtain a so called secure sketch from which no information regarding the biometric data or the key can be retrieved again, cancelable biometric template transformation techniques non-invertibly transform the biometric template with the user‘s password. To analyze and improve the biometric cryptosystems, we have studied its two main exam...
Multi-biometric Template Protection: An Overview
Renewable Energy for Smart and Sustainable Cities, 2018
Today, biometrics is a research field in full expansion, several identification and verification systems are now being developed, however their performance is inadequate to meet the growing needs of security. The use of a single biometric modality decreases, in most cases, the reliability of these systems, which prompted us to combine several modality. This article provides a complementary aspect to the improved performance of biometric systems namely the protection of privacy. Techniques have been proposed in the last decade on the biometric template protection. Include BioHashing that wants a generalization of biometrics a hash function to protect the biometric data. The main objective is the protection of privacy. This paper presents state of the art specific algorithms, which are illustrated with recent work by researchers in this field.
A Lightweight Approach for Biometric Template Protection (Proceedings Paper)
spie.org
Privacy and security are vital concerns for practical biometric systems. The concept of cancelable or revocable biometrics has been proposed as a solution for biometric template security. Revocable biometric means that biometric templates are no longer fixed over time and could be revoked in the same way as lost or stolen credit cards are. In this paper, we describe a novel and an efficient approach to biometric template protection that meets the revocability property. This scheme can be incorporated into any biometric verification scheme while maintaining, if not improving, the accuracy of the original biometric system. However, we shall demonstrate the result of applying such transforms on face biometric templates and compare the efficiency of our approach with that of the well-known random projection techniques. We shall also present the results of experimental work on recognition accuracy before and after applying the proposed transform on feature vectors that are generated by wavelet transforms. These results are based on experiments conducted on a number of well-known face image databases, e.g. Yale and ORL databases.
An Overview of Biometric Template Security Techniques
Security remains to be an important aspect in the current age that is characterized with heavy internet usage. People as well as organizations are moving away from ancient authentication schemes like passwords to biometric authentication schemes as they provide better confidentiality and integrity of authentication information. Although biometrics are unique to an individual, they are still susceptible to attacks thus the need to secure them. Several techniques such as encryption, steganography, have been proposed with aim of achieving the security need brought about their use. This paper reviewed some proposed models for biometric template security and their limitation as well as provide recommendation to address some of the limitations outlined.
The need for fool proof authentication procedures away from traditional authentication mechanisms like passwords, security PINS has led to the advent of biometric authentication in information systems. Biometric data extracted from physiological features of a person including but not limited to fingerprints, palm prints, face or retina for purpose of verification & identification is saved as biometric templates. The inception of biometrics in access control systems has not been without its own hitches & like other systems it has its fair share of challenges. Biometric fingerprints being the most mature of all biometric spheres are the most widely adopted biometric authentication systems. Biometric systems effectiveness lies on how secure they are at preventing inadvertent disclosure of biometric templates in an information system’s archive. This however has not been the case as biometric templates have been fraudulently accessed to gain unauthorized access in identification and verification systems. In order to achieve strong and secure biometric systems, biometric systems developers need to build biometric systems that properly secure biometric templates. Several biometric template protection schemes and approaches have been proposed and used to safeguard stored biometric templates. Despite there being various biometric template protection schemes and approaches in existence, none of them has provided the most authentic, reliable, efficient and deterrent means to totally secure biometric fingerprint templates. This research sought to establish status of the current biometric template protection techniques and methods by conducting a survey and analyzing data gathered from a sample of seventy-eight (78) respondents. We will report these results and give our conclusion based on findings of the survey in this paper.
