Assessment of microbiological growth on biometric devices

Biometric devices are nowadays common in use for a variety of purposes. The current study aims to assess the bacteria growth on fingerprint scanners and morphological identification of the bacteria. The bacteria growth was determined through the colony forming units followed by morphological identification through hanging drop method and gram staining. The results showed the bacteria growth curve for dilution factor 10-6 showed the most accurate growth curve graph and was chosen for morphological identification. From morphological identification, the bacteria was observed for three days and from observation the bacteria’s growth moderately. Next, from gram staining method, the bacteria appeared reddish which mean its Gram-negative bacteria. Gram-negative bacteria are among the most significant public health problems in the world due to their high resistance to antibiotics so the recommendation is to change the use of biometric devices to more safe ways to avoid the spread of microorganisms in this pandemic era such as using online attendance system and using staff card. This study has been significant because it can confirm the existing of microorganisms on the surface of biometric devices as well as the types of the microbes by determining the bacteria growth and bacteria identification.

Change in perception regarding the use of Biometric devices at a tertiary care hospital in view of COVID-19

Background: Fingerprint biometric systems are used to identify personnel, grant authorised access and maintain attendance of staff at most places. Despite their many benefits, biometric devices are potential sources of transmission due to contamination from multiple touches by various users. Due to the COVID-19 pandemic, there have been massive shift in infection control practices specially hand hygiene. This study was conducted to understand the attitude and practices of healthcare workers (HCWs) they are likely to follow when biometric devices come to use again. Materials and Methods: The study was conducted using a self-designed questionnaire given to HCWs in different departments of the hospital in the form of a written form by our infection control nurses. The study was conducted for 5 days. The questionnaire was based on various attitudes and practices before and after the COVID-19 outbreak. Results: Overall 304 participants filled the questionnaire, which comprised 85 (28%) doctors, 117 (38.4%) nurses and 102 (33.6%) other staff. Before the emergence of COVID-19, 114 (37.5%) participants felt touching biometric devices is more dangerous than touching other common items such as doorknobs, elevator buttons, countertops and staircase railings which now increased to 183 (60.2%) after the COVID-19. Earlier 77% of participants felt that hand sanitisers should be installed near biometric devices, but now 95.7% feel the need of hand sanitisers near the biometric devices and want to use them. Conclusion: This improvement in hand hygiene might be a result of increased awareness through educational programmes and mass media during the COVID-19 pandemic. Hand sanitisers should be installed near biometric devices before restarting their use which will reduce the risk of contamination of biometric devices by pathogenic organisms.

Intending to err: the ethical challenge of lethal, autonomous systems

Current precursors in the development of lethal, autonomous systems (LAS) point to the use of biometric devices for assessing, identifying, and verifying targets. The inclusion of biometric devices entails the use of a probabilistic matching program that requires the deliberate targeting of noncombatants as a statistically necessary function of the system. While the tactical employment of the LAS may be justified on the grounds that the deliberate killing of a smaller number of noncombatants is better than the accidental killing of a larger number, it may nonetheless contravene a reemerging conception of right intention. Originally framed by Augustine of Hippo, this lesser-known formulation has served as the foundation for chivalric code, canon law, jus in bello criteria, and the law of armed conflict. Thus it serves as a viable measure to determine whether the use of lethal autonomy would accord with these other laws and principles. Specifically, examinations of the LAS through the lenses of collateral damage, the principle of double effect, and the principle of proportionality, reveal the need for more attention to be paid to the moral issues now, so that the promise of this emerging technology--that it will perform better than human beings--might actually come to pass.

Daubechies Wavelet Based Compression and Denoising Techniques for Biometric Images

Finger print readers and retinal eye scanners have been an integral aspect of research and space organisations, forensic tests and so on. But to use it on a daily basis, Image compression is a necessary aspect considering the huge population of our country. Wavelet transform provides a platform for this process. In this paper, a novel idea to implement wavelet transform based on Daubechies wavelets has been discussed. The paper also discusses the concepts of linear transform, quantization, dequantization and image denoising. The image is first transformed using discrete wavelet transform to obtain the wavelet coefficients. The process of image compression is achieved by quantizing and encoding the coefficients. Uniform scalar quantization is done on the basis function coefficients in order to reduce their precision by reducing the number of bits required to store the transformed coefficients. The resulting quantized coefficients are then encoded using Huffman entropy encoding. In order to ensure that the image is free from disturbances like noise signals, denoising technique has been implemented using the wavelet coefficients. A paper of such an application has been proposed to tackle the global phenomenon of terrorism through the use of biometric devices including finger print reader and retinal eye scanner.

A Comparative Study of Biometric Technologies with Reference to Human Interface

Traditionally the use of biometric devices has improved our ability to provide authenticated access to physical installations. Biometrics is the use of a person‟s unique physiological, behavioral, and morphological characteristic to provide positive personal identification. Biometric systems that are currently available today examine fingerprints, handprints, iris and retina patterns, and face. Systems that are close to biometrics but are not classified as such are behavioral systems such as voice, signature and keystroke systems. They test patterns of behavior not parts of the body. Over the next few years, the use of biometrics will continue to grow and become much more commonplace. Today the core technologies have evolved and the cost of the equipment is going down dramatically due to the integration and increasing processing power. Certain applications of biometric identification technology are now cost-effective, reliable and highly accurate. As a result, there is no technological or financial barrier for stepping from the pilot projects to widespread deployment. This paper is an attempt to highlights the biometric technologies in concern with human interface.

How to Protect Patients Digital Images/Thermograms Stored on a Local Workstation

To ensure the security and privacy of patient electronic medical information stored on local workstations in doctors’ offices, clinic centers, etc., it is necessary to implement a secure and reliable method for logging on and accessing this information. Biometrically-based identification technologies use measurable personal properties (physiological or behavioral) such as a fingerprint in order to identify or verify a person’s identity, and provide the foundation for highly secure personal identification, verification and/or authentication solutions. The use of biometric devices (fingerprint readers) is an easy and secure way to log on to the system. We have provided practical tests on HP notebooks that have the fingerprint reader integrated. Successful/failed logons have been monitored and analyzed, and calculations have been made. This paper presents the false rejection rates, false acceptance rates and failure to acquire rates.

Verification and Validation of a Fingerprint Image Registration Software

The need for reliable identification and authentication is driving the increased use of biometric devices and systems. Verification and validation techniques applicable to these systems are rather immature and ad hoc, yet the consequences of the wide deployment of biometric systems could be significant. In this paper we discuss an approach towards validation and reliability estimation of a fingerprint registration software. Our validation approach includes the following three steps: (a) the validation of the source code with respect to the system requirements specification; (b) the validation of the optimization algorithm, which is in the core of the registration system; and (c) the automation of testing. Since the optimization algorithm is heuristic in nature, mathematical analysis and test results are used to estimate the reliability and perform failure analysis of the image registration module.

A Comparative Analysis of Opinions of Americans, Australians and Malaysians on the Use of Biometric Devices in Workplaces for Security and Monitoring of Worker Productivity

Since the September 11, 2001 terrorist attacks in New York, the use of biometric devices such as fingerprint scans, retina and iris scans and facial recognition in everyday situations for national security and border control, have become commonplace. This has resulted in the biometric industry moving from being a niche technology to one that is ubiquitous. As a result. more and more employers are using biometrics to secure staff access to their facilities as well as for tracking staff work hours, maintaining 'discipline' and carry out surveillance against thefts. detecting work hour abuses and fraud. However, the data thus collected and the technologies themselves are feared of having the potential for and actually being misused - both in terms of the violating staff privacy and discrimination and oppression of targeted workers. This paper examines the issue of using biometric devices in organisational settings their advantages, disadvantages and actual and potential abuses from the point of view of critical theory. From the perspectives of Panoptic surveillance and hegemonic organisational control, the paper examines the issues related to privacy and identification, biometrics and privacy, biometrics and the 'body', and surveillance and modernity. The paper also examines the findings ofa survey carried out in Australia. Malaysia and the USA on respondents' opinions on the use of biometric devices in everyday life including at workplaces. The paper concludes that along with their applications in border control and national security, the use of biometric devices should be covered by relevant laws and regulations. guidelines and codes of practice. in order to balance the rights to privacy and civil liberties of workers with employers' need for improved productivity, reduced costs, safeguards related to occupational health and safety, equal opportunity, and workplace harassment of staff and other matters, that employers are legally responsible for.

A Comparison of Australian and Malaysian Views on the Use of Biometric Devices in Everyday Situations

Since the September 11, 2001 terrorist attacks in New York City, many countries including Australia and Malaysia have been able to justify the use biometric devices such as finger print scans, retina scans and facial recognition for identification and surveillance of its citizens and others in the name of national security. In addition, biometric devices are increasingly being used worldwide by organizations to keep track of their employees and their productivity, leading to concerns of privacy, the safety, reliability, abuse and misuse of the data collected and violations of civil liberties. Taking the critical theory perspective, this paper will analyse the data collected and report on the findings of a survey carried out in Australia and Malaysia, with respect to the responses provided and opinions expressed to the survey s open ended and other questions by individuals as to their current use, experiences, preferences, concerns about the devices and the situations in which they think biometric devices should be used, including in their workplaces. This descriptive study uses both quantitative and qualitative data to examine what Australians and Malaysians think about the use of biometric devices in everyday situtions and compare them as to their similarities and differences. The paper will then critically examine the ethical and civil liberties issues involved in the use of biometric devices in everyday life and argues that regulatory and legal measures should be taken to safeguard the rights of citizens while maintaining national security and productivity, in order to avoid the situation of Michel Foucaults Panopticon becoming an unpleasant everyday reality, which could negatively irifluence socialjustice and create social change due to its effects on individuals in two multicultural societies. The paper will argue about the need to educate the general public as to the issues of surveillance and privacy involved in the use of biometric devices in everyday situations.

Body language, security and e‐commerce

Security is becoming an increasingly more important concern both at the desktop level and at the network level. This article discusses several approaches to authenticating individuals through the use of biometric devices. While libraries might not implement such devices, they may appear in the near future of desktop computing, particularly for access to institutional computers or for access to sensitive information. Other approaches to computer security focus on protecting the contents of electronic transmissions and verification of individual users. After a brief overview of encryption technologies, the article examines public‐key cryptography which is getting a lot of attention in the business world in what is called public key infrastructure. It also examines other efforts, such as IBM’s Cryptolope, the Secure Sockets Layer of Web browsers, and Digital Certificates and Signatures. Secure electronic transmissions are an important condition for conducting business on the Net. These business transactions are not limited to purchase orders, invoices, and contracts. This could become an important tool for information vendors and publishers to control access to the electronic resources they license. As license negotiators and contract administrators, librarians need to be aware of what is happening in these new technologies and the impact that will have on their operations.

Security considerations in the use of biometric devices

Abstract The biometric device and subsystem represent only a part of a complete security solution. System designers who are considering the use of this novel approach to authentication need to consider how its use will impact the other components. In addition, new threats and vulnerabilities may be introduced —especially if such devices are viewed as simple replacements of existing methods. Each domain of application will present its own challenges, but there are a number of common concerns which the prudent designer should address.
