They are metrics related to human characteristics and they are typically identified and utilized on an individual basis. Biometric data points can include things like: ▪ Fingerprints ▪ Body odor ▪ DNA ▪ Palm veins ▪ Face recognition ▪ Ear form ▪ Palm prints ▪ Keyboard strokes ▪ Iris recognition ▪ Gait analysis ▪ Hand geometry ▪ Voice ▪ Retina ▪ Body geometry ▪ Biometric data is primarily used for identification but also for authentication. ▪ Hardware-based recognition system - Data is stored on a specific piece of hardware and works with the device to recognize the data, without storing the data on the device itself. ▪ Portable token system - A fob or a smart card to store biometric data. When using this method, the user will need to present their card or fob and then their biometric data as a two-step authentication process. ▪ Biometric server- Data is held on an external server and it is more susceptible to cyber attacks. To reduce the risk of data being breached, it must be encrypted when being transferred over the network. The issue with encryption is deciding where encryption keys will be stored and who will be trusted with access. ▪ Use of biometric data isn’t new and the police have been fingerprinting people for over a century and have had biometric databases since the ’80s. ▪ The U.S. Department of Homeland Security (DHS) takes approximately 300,000 fingerprints per day from non-U.S. citizens crossing the border into the United States, and it collects biometrics from noncitizens applying for immigration benefits and from immigrants who have been detained. ▪ Any individual who applies for employment with the federal government or a sensitive position requiring a background check will be asked to supply a fingerprint ▪ State and local law enforcement officers regularly collect fingerprints and DNA, as well as face prints and even iris scans. ▪ As of January 2020, it is legal in 46 states for software to identify an individual using images taken without consent while they are in public. ▪ Any individual who applies for a driver’s license will provide a face-recognition ready photographs. ▪ Recent advances in camera and surveillance technology have improved the accuracy of biometrics capture and identification at a distance, making unobtrusive collection easier. ▪ Private and public security cameras in use by police are more capable of capturing the facial features to support facial recognition-based searches. ▪ Two of the world’s largest biometrics databases are the FBI’s Integrated Automated Fingerprint System (IAFIS) and DHS’s Automated Biometric Identification System (IDENT). ▪ IAFIS includes over 71 million subjects in the criminal master file and more than 33 million civil fingerprints. ▪ IDENT stores biometric and biographical data for individuals who interact with the various agencies under the DHS umbrella and contains over 130 million fingerprint records on its files. ▪ In addition to the federal databases, each of the states has its own biometric databases – generally a fingerprint database and a DNA database. ▪ Facebook has one of the best-known private biometrics database. ▪ Facebook’s face recognition service allows users to find and tag their friends which has seen dramatic increases in accuracy due to the volume of photos uploaded and tagged on Facebook. ▪ Facebook currently has over 845 million monthly active users and requires each one of those users to sign up under their real names, and then makes its users’ names and primary photos public by default. ▪ “Google Photos” which houses over a million of pictures uses similar technology that extracts and analyzes data from the points and contours of faces that appear in photos taken on Google Android devices. ▪ Template that Google extracts is unique to an individual, in the same way that a fingerprint or voiceprint uniquely identifies one and only one person and is used to organize and group together photos based upon the individuals appearing in the photos. ▪ What does the Government say? Biometrics databases can be used effectively for border security, to verify employment, to identify criminals, and to combat terrorism. ▪ What does the Private Organizations say? Biometrics can enhance our lives by helping us to identify our friends more easily and by allowing us access to places, products, and services more quickly and accurately. ▪ Biometrics’ biggest risk to privacy comes from the government’s ability to misuse it for surveillance. ▪ The problems are multiplied when biometrics databases are “multimodal,” allowing the collection and storage of several different biometrics in one database and combining them with traditional data points like name, address, social security number, gender, race, and date of birth. ▪ Geolocation tracking technologies built on top of large biometrics collections could enable constant surveillance. And if the government gets its way, all of this data could be obtained without a warrant and without notice or warning. ▪ Standardization of biometric databases causes additional problems as the data once standardized becomes much easier to use as linking identifiers, not just in interactions with the government but also across disparate databases and throughout the society. ▪ Large standardized collections of biometrics could lead to many vulnerable copies of that linked data that could wind up in the hands of identity thieves. ▪ Biometric data compromises would be catastrophic as unlike a credit card number or a password, your biometric data can’t be revoked or re-issued. ▪ Extensive data retention times can lead to additional problems. Biometric records stored in IDENT are retained for 75 years or until the statue of limitations for all criminal violations has expired. ▪ Civil fingerprints stored in IAFIS are not destroyed until the individual reaches 75 years of age and the criminal fingerprints are not destroyed until the individual reaches 99 years of age. ▪ Due to the usage of advanced facial recognition technologies in crowd and security cameras, anyone could end up in the database, even if they aren’t involved in a crime. ▪ By happening to be in the wrong place at wrong time. ▪ By fitting a stereotype that some in society have decided is a threat. ▪ Data sharing can also mean that data collected for non-criminal purposes, such as immigration-related records, is combined with and being used for criminal or national-security purposes with little to no standards, oversight, or transparency. ▪ If any of the data in the system is inaccurate and propagated throughout several other systems, it can be extremely difficult to correct. ▪ A private entity in possession of biometric identifiers or biometric information must develop a written policy, made available to the public, establishing a retention schedule and guidelines for permanently destroying biometric identifiers and biometric information when the initial purpose for collecting or obtaining such identifiers or information has been satisfied or within 3 years of the individual's last interaction with the private entity, whichever occurs first. ▪ Absent a valid warrant or subpoena issued by a court of competent jurisdiction, a private entity in possession of biometric identifiers or biometric information must comply with its established retention schedule and destruction guidelines. ▪ No private entity may collect, capture, purchase, receive through trade, or otherwise obtain a person's or a customer's biometric identifier or biometric information, unless it first informs the subject or the subject's legally authorized representative in writing ▪ That a biometric identifier or biometric information is being collected or stored; ▪ The specific purpose and length of term for which a biometric identifier or biometric information is being collected, stored, and used; ▪ and receives a written release executed by the subject of the biometric identifier or biometric information or the subject's legally authorized representative. ▪ No private entity in possession of a biometric identifier or biometric information may sell, lease, trade, or otherwise profit from a person's or a customer's biometric identifier or

The system consists of multiple clients and an authentication server. Client, a smartphone with accompanying application, is used to capture biometrics, manage auxiliary data and create and store encrypted cancelable templates. Bank’s authentication server manages encryption keys and provides the template verification service. Proposed system keeps biometric templates encrypted or at least cancelable during all stages of storage, transmission and verification. As templates are stored on clients in encrypted form and decryption keys reside on bank's authentication server, original plaintext templates are unavailable to an adversary if the phone gets lost or stolen. The system employs public key cryptography and pseudorandom number generator on small-sized templates, thus not suffering from severe computational costs like systems that employ homomorphic encryption. System is also general, as it does do not depend on specific cryptographic algorithms. Having in mind that modern smartphones have iris scanners or at least high- quality front cameras, and that no severe computational drawbacks exist, one may conclude that the proposed authentication framework is highly applicable in mobile banking authentication.

    Advances in Fingerprint Recognition at CUBS Venu Govindaraju Director of Center for Unified Biometrics and Sensors University at Buffalo, State University of New York [email protected] Abstract The Center for Unified Biometrics and Sensors (CUBS) at the University at Buffalo, SUNY is developing biometrics identification systems for civilian, law enforcement and homeland security applications. The center is involved in traditional research developing matching algorithms for several biometric modalities (e.g., fingerprint, signature, face) and in identifying exploratory areas of research that will address problems anticipated in wide- scale deployment of biometrics. In this paper we describe some of our recent research in fingerprint verification. In particular, we will describe a new non-stationary fingerprint enhancement algorithm based on Fourier domain analysis and a partial fingerprint matching algorithm that uses novel approaches from graph and optimization theory. We will also present new score computation algorithm that treats fingerprint verification as a classification problem. Finally, we will describe a novel technique for protecting the privacy and security of fingerprint templates that is based on symmetric hash functions. INTRODUCTION In an increasingly digital world, reliable personal authentication is an important human computer interface activity. National security, e-commerce, and access to computer networks are some examples where establishing a person's identity is vital. Existing security measures rely on knowledge-based approaches like passwords or token-based approaches such as swipe cards and passports to control access to physical and virtual spaces. Though ubiquitous, such methods are not very secure. Tokens such as badges and access cards may be shared or stolen.

    ASAKER and ZAHRAN BIOMETRICS SECURITY AND PRIVACY PROTECTION AHMED A. ASAKER Reactors Department, Nuclear Research Center – Egyptian Atomic Energy Authority Cairo, Egypt Email: [email protected] OSAMA ZAHRAN Department of Electronics and Electrical Communication Engineering, Faculty of Electronic Engineering Menoufia University, Menoufia, Egypt Email: [email protected] Abstract Physical security at nuclear facilities is an important licensing and design consideration. The ultimate objective of the physical protection system (PPS) is to prevent the accomplishment of unauthorized overt or covert actions to nuclear facilities and nuclear materials. When a physical protection system is applied to a nuclear facility or to nuclear materials, its objective is to prevent radiological sabotage of facilities and theft of nuclear materials. Thus an effective system of physical protection also plays an important role in preventing illicit trafficking of nuclear materials. One of the main pillars of physical protection is controlling personnel access to facilities via Identification technology Systems. Identification technology is changing as fast as the facilities, information, and communication it protects. Recent years have seen a rapid adaptation of using various biometric systems for trusted human automatic recognition and controlling personnel access to nuclear facilities attributed to its high accuracy performance, discriminability, difficulty to be imitated and faked, and stability. Biometrics refers to the physiological or behavioural characteristics of an individual. Many physical characteristics, such as face, fingerprints, iris and behavioural characteristics, such as voice and gait are believed to be unique to an individual. With the exponential growth of using biometric systems, there is an increasing concern that the privacy anonymity of individuals can be compromised by biometric technologies.

    Beyond PKI: the Biocryptographic Key Infrastructure Beyond PKI: the Biocryptographic Key Infrastructure

    Beyond PKI: The Biocryptographic Key Infrastructure Beyond PKI: The Biocryptographic Key Infrastructure W.J. Scheirer, W. Bishop and T.E. Boult Abstract Public Key Infrastructure is a widely deployed security technology for handling key distribution and validation in computer security. Despite PKI’s popu- larity as a security solution, Phishing and other Man-in-the-Middle related attacks are accomplished with ease throughout our computer networks. The major problems with PKI come down to trust, and largely, how much faith we must place in crypto- graphic keys alone to establish authenticity and identity. In this chapter, we look at a novel biometric solution that mitigates this problem at both the user and certificate authority levels. More importantly, we analyze the problem of applying unprotected biometric features directly into PKI, and propose the integration of a secure, revoca- ble biometric template protection technology that supports transactional key release. A detailed explanation of this new Biocryptographic Key Infrastructure is provided, including composition, enrollment, authentication, and revocation details. The BKI provides a new paradigm for blending elements of physical and virtual security to address network attacks that more conventional approaches have not been able to stop. 1 Introduction To motivate the contribution of this paper, we first turn to the technology that under- pins the problem. Public Key Infrastructure (PKI) [10, 1, 9, 30] has been a popular, yet often maligned technology since its widespread adoption in the 1990s. PKI (Fig- W. J. Scheirer and T.E.

Abstract: The use of biometric for identification purposes requires that a particular biometric factor be unique for each individual that it can be calculated, and that it is invariant over time. Biometrics such as signatures, photographs, fingerprints, voiceprints and retinal blood vessel patterns all have noteworthy drawbacks. Although signatures and photographs are cheap and easy to obtain and store, they are impossible to identify automatically with assurance, and are easily forged. Human iris on the other hand as an internal organ of the eye and as well protected from the external environment, yet it is easily visible from within one meter of distance makes it a perfect biometric for an identification system with the ease of speed, reliability and automation. Iris recognition is regarded as the most reliable and accurate biometric identification system available.

Biometric data are, however, sensitive and vulnerable, and there is a need to develop biometric applications as a privacy-enhancing technology (PET) rather than a privacy- invasive technology (PIT). Building on earlier FIDIS research, this report studies technical, organizational, and policy decisions in the development of biometrics applications that influence their becoming PETs or PITs. These decisions balance the interests of individuals to have control over their pers- onal data against commercial, societal, and political interests, security, con- venience, and efficiency. This report identifies criteria for determining the ‘PET’ content of technologies and looks at several case studies of decision- making processes in biometrics: biometric pseudonyms and iris recognition, Privacy Impact Assessments, voice recognition, the German ePass, and the Dutch central database of passport biometrics. These case studies suggest a possible gap between expectations and assessments based on technical knowledge and between economic and political expectations of and require- ments for biometric applications. Based on this finding, recommendations are given to enhance awareness of privacy-enhancing technologies and to apply value-sensitive design in the development of biometric applications.
