Biometrics is the only true means of linking or binding digital identities to the individual

A number of misconceptions exist about the capabilities and technology of
biometrics, perpetuated in popular culture by films and TV

Like many categories in the security marketplace, the biometrics market suffers its share of misconceptions, ranging from misunderstanding of the technology to underestimating its utility for a broad range of uses.

Misunderstandings created by pop culture

Contributing to the problem of understanding is the popular culture. “Popular movies such as James Bond and Mission Impossible have created many misconceptions and misunderstandings regarding biometrics,” says Robert Fee, Director of Sales, Access Control, Zwipe. “We all see them create perfect copies within minutes, and enter buildings or highly secured areas. If it was that easy, there would not be a multi-billion-dollar-a-year industry.” Another misconception that comes up is that a fingerprint template stored on one device works exactly the same with any other biometric device, says Fee.

There is also a misconception that someone can steal and use a digital version of a person’s unique biometric, says Phil Scarfo, VP Worldwide Marketing, Biometrics, HID Global. “Some of the more advanced technologies like multispectral imaging [from HID Global] can identify human tissue as authentic, quickly detect fraudulent materials and respond and adapt to new vulnerabilities with a ‘learning’ capability that keeps up with new threats,” he says.

Another misconception is that all biometrics devices and solutions are created equal. “What may be right for a mobile device and consumer application is not sufficient for commercial or enterprise applications,” says Scarfo. While there is the fear by some that biometrics poses a threat to personal privacy or a potential permanent loss of digital identity if it is stolen or compromised, it is far outweighed by the measureable benefits, he says. Ironically, the focus historically has been more on the potential risks rather than the benefits, adds Scarfo.

Biometrics binding digital identities to individuals

Most people don’t fully appreciate the critical importance of biometrics in an increasingly complex world of digital identities and ever-expanding ecosystem of ID cards, phones and other devices, says Scarfo. Biometrics is the only true means of linking or binding digital identities to the individual, determining who is actually using the system, and verifying whether he or she is a legitimate user for a myriad of new mobile and on-line applications. “The ability to securely link or bind digital identities to ourselves will simplify life and make it more secure,” says Scarfo. “Intelligently coupling what we have with who we are is a much better way forward in today’s complex digital world.”

Misconceptions also persist around cost and ease of use, according to Steve Perna, Executive Director, Products and Solutions Division, SRI International. “Today’s biometrics systems are reliable, cost-feasible (particularly from a lifecycle cost perspective), and deliver ease of use,” he says. “Costs are being driven down across all aspects of the biometrics ecosystem, from underlying technologies and platforms to the devices themselves.”

People are apprehensive about sharing their biometric information out of fear of how their information can be exploited maliciously

As prices reduce, functionality and features improve, and technologies become more mobile, biometrics is becoming an increasingly attractive form of security

Misconceptions related to privacy

There are also misconceptions related to privacy. People are apprehensive about sharing their biometric information out of fear of how their information can be exploited maliciously, says Arie Melamed Yekel, CMO, FST Biometrics. “However, these concerns are unfounded.” Much of an individual’s biometric information is already available publicly, whether registered through a governmental database, or facial/body/voice images and videos available on public social media profiles, he says. “In fact, entering one’s biometric information into a system such as FST Biometrics’ is much more secure since we take care to encrypt our data and protect our users,” he says.

ZKAccess sees a big misconception is that biometric devices capture the actual image of a person’s fingerprint or face when enrolled. This creates a privacy concern for users that their fingerprint/face image can be compromised and subsequently used or shared without their permission, resulting in personal and/or financial harm to them. Biometrics do not capture live images. "Biometrics and fingerprinting are not the same,” says Larry Reed, CEO, ZKAccess.

The commonly observed method of “fingerprinting” (seen on television and in hospitals/government facilities) is also known as an AFIS (an Automated Fingerprint Identification System, which uses digital imaging technology to obtain, store and analyse fingerprint data and originally used by the U.S. Federal Bureau of Investigation [FBI] in criminal cases). However, commercial biometric systems do not store/match actual images. Instead, biometric devices capture and store only a few dozen minutia points on the finger or face, apply proprietary mathematical algorithms, and convert those minutia points into binary code (i.e., a series of zeros and ones). “If you were handed a pencil and told to draw someone’s face by using 40 to 50 dots, would anyone recognise the face you drew?” Reed asks.  “This is how biometrics capture, store and match templates. Only binary code is used.”

Early adopters of fingerprint readers

Some misunderstanding of biometrics stems from suboptimal experiences of early adopters of fingerprint readers for access control, says Steve Perna.But the truth is that, in most cases, organisations didn’t try and abandon biometrics,” he says. “More likely they never adopted it due to stories they heard that impacted public perception. In other cases, higher prices dampened enthusiasm.”

However, Perna says these impediments to adoption continue to fade, as prices come down, functionality and features improve, and as biometrics become inherently mobile and can deliver benefits beyond access control, such as time-and-attendance tracking, inventory management and logical access to other applications.

How has security industry training changed in the last year?
How has security industry training changed in the last year?

In-person training sessions were mostly canceled during the worst of the COVID-19 pandemic. However, the need for training continued, and in some cases increased, as the security industry sought to adapt to the changing business climate of a global emergency. So how well did we as an industry adjust? We asked this week’s Expert Panel Roundtable: How has security industry training changed in the last year?

Physical access control: Critical steps to ensure a smarter future
Physical access control: Critical steps to ensure a smarter future

Steven Kenny, Axis Communications, looks at the benefits of physical access control systems within smart environments, and how knowledge gaps and dated methods can inhibit adoption. Physical security is becoming more dynamic and more interconnected, as it evolves. Today’s modern access control solutions are about so much more than simply opening doors, with digitalisation bringing multiple business benefits, which would simply not be possible using traditional models. Digital transformation While the digital transformation of processes and systems was already well underway, across many industries and sectors, it is the transformation of physical security from a standalone, isolated circuit, to a network-enabled, intelligent security solution that brings many benefits to the smart environment. Yet, with more organisations now looking to bring their physical security provision up to date, there are many considerations that must be addressed to maximise the potential of access control and video surveillance. Not least of which is that connecting physical security devices to a network presents risk, so it is increasingly important for IT teams to play a role in helping to facilitate the secure integration of physical and network technologies, as these two worlds increasingly converge. Improved access control in smart environments These urban constructs are capable of reducing waste, driving efficiencies and optimising resources The smart city offers significant benefits, reflected in the US$ 189 billion that is anticipated to be spent on smart city initiatives globally by 2023. These urban constructs are capable of reducing waste, driving efficiencies, optimising resources and increasing citizen engagement. Technology, which is increasingly being incorporated to protect access points within the smart environment, can take many forms. These range from simple card readers to two factor authentication systems, using video surveillance as a secondary means of identification, right through to complex networks of thermal cameras, audio speakers and sensors. Frictionless access control During the COVID-19 pandemic, frictionless access control has provided an effective ‘hands free’ means of accessing premises, using methods such as QR code readers and facial recognition as credentials to prove identity. Frictionless access control brings health and safety into the equation, as well as the security of entrances and exits, minimising the risk of infection, by removing the need to touch shared surfaces. Such systems can be customised and scaled to meet precise requirements. Yet, an increasing integration with open technologies and platforms requires collaboration between the worlds of physical security and IT, in order to be successful. Barriers to adoption Traditional suppliers and installers of physical security systems have built up a strong business model around their expertise, service and knowledge. Network connectivity and the IoT (Internet of Things) present a constantly shifting landscape, requiring the traditional physical security vendor to learn the language of IT, of open platforms, IP connectivity and software integration, in order to adapt to market changes and remain relevant. Many are now beginning to realise that connected network-enabled solutions are here to stay Those who cannot adapt, and are simply not ready for this changing market, risk being left behind, as the physical security landscape continues to shift and demand continues to increase. With end users and buyers looking for smarter, more integrated and business-focused solutions from their suppliers, it is clear that only those who are prepared will succeed in this space. Time will not stand still, and many are now beginning to realise that connected network-enabled solutions are here to stay, particularly within smart constructs which rely on such technology by their very nature. The importance of cyber hygiene Connecting any device to a network has a degree of risk, and it is, therefore, imperative that any provider not only understands modern connected technologies, but also the steps necessary to protect corporate networks. Cameras, access control systems and IP audio devices, which have been left unprotected, can potentially become backdoors into a network and used as access points by hackers. These vulnerabilities can be further compromised by the proliferation of connected devices within the Internet of Things (IoT). While the connection of devices to a network brings many advantages, there is greater potential for these devices to be used against the very business or industry they have been employed to protect when vulnerabilities are exploited. Cyber security considerations Cyber security considerations should, therefore, be a key factor in the development and deployment of new security systems. Access control technologies should be manufactured according to recognised cyber security principles, incident reporting and best practices. It is important to acknowledge that the cyber integrity of a system is only as strong as its weakest link and that any potential source of cyber exposure will ultimately impact negatively on a device’s ability to provide the necessary high levels of physical security. The future of access control There is a natural dispensation towards purchasing low-cost solutions There is a natural dispensation towards purchasing low-cost solutions that are perceived as offering the same value as their more expensive equivalents. While some have taken the decision to implement such solutions, in an attempt to unlock the required benefits, while saving their bottom line, the limited lifespan of these technologies puts a heavier cost and reputational burden onto organisations by their association. The future of access control, and of physical security as a whole, will, therefore, be dependent on the willingness of suppliers to implement new designs and new ways of thinking, based around high-quality products, and to influence the installers and others in their supply chains to embrace this new world. Cyber security key to keeping businesses safe In addition, cyber security considerations are absolutely vital for keeping businesses safe. The integration of cyber secure technologies from trusted providers will provide peace of mind around the safety or corporate networks, and integrity of the deployed technologies. As we move forward, access control systems will become data collection points and door controllers will become intelligent I/O devices. QR codes for visitor management and biometric face recognition for frictionless access control will increasingly be managed at the edge, as analytics in a camera or sensor. The future of access control presents an exciting and challenging time for those ready to accept it, to secure it and to help shape it, offering a true opportunity to innovate for a smarter, safer world.

Wire-free, mobile first and data rich? The future of access control is within almost anyone’s reach
Wire-free, mobile first and data rich? The future of access control is within almost anyone’s reach

The 2020s will be a wireless decade in access control, says Russell Wagstaff from ASSA ABLOY Opening Solutions EMEA. He examines the trends data, and looks beyond mobile keys to brand new security roles for the smartphone. The benefits of wire-free electronic access control are well rehearsed. They are also more relevant than ever. A wireless solution gives facility managers deeper, more flexible control over who should have access, where and when, because installing, operating and integrating them is easier and less expensive than wiring more doors. Battery powered locks Many procurement teams are now aware of these cost advantages, but perhaps not their scale. Research for an ASSA ABLOY Opening Solutions (AAOS) benchmarking exercise found installation stage to be the largest contributor to cost reduction. Comparing a typical installation of battery-powered Aperio locks versus wired locks at the same scale, the research projected an 80% saving in installers’ labour costs for customers who go cable-free. Battery powered locks all consume much less energy than traditional wired locks Operating costs are also lower for wireless: Battery powered locks all consume much less energy than traditional wired locks, which normally work via magnets connected permanently to electricity. Wireless locks only ‘wake up’ when presented with a credential for which they must make an access decision. AAOS estimated a 70% saving in energy use over a comparable lock’s lifetime. Find out more about wireless access control at ASSA ABLOY's upcoming 29th June webinar Deploying wireless locks In short, every time a business chooses a wireless lock rather than a wired door, they benefit from both installation and operating cost savings. A recent report from IFSEC Global, AAOS and Omdia reveals the extent to which the advantages of wireless are cutting through. Responses to a large survey of security professionals — end-users, installers, integrators and consultants serving large corporations and small- to medium-sized organisations in education, healthcare, industrial, commercial, infrastructure, retail, banking and other sectors — suggest almost four locations in ten (38%) have now deployed wireless locks as a part or the whole of their access solution. The corresponding data point from AAOS’s 2014 Report was 23%. Electronic access control Electronic access control is less dependent than ever on cabling Without doubt, electronic access control is less dependent than ever on cabling: Even after a year when many investments have been deferred or curtailed, the data reveals fast-growing adoption of wireless locks, technologies and systems. Is mobile access control — based on digital credentials or ‘virtual keys’ stored on a smartphone — an ideal security technology for this wire-free future? In fact, the same report finds mobile access is growing fast right now. Among those surveyed, 26% of end-users already offer mobile compatibility; 39% plan to roll out mobile access within two years. Before the mid-2020s, around two-thirds of access systems will employ the smartphone in some way. The smartphone is also convenient for gathering system insights Driving rapid adoption What is driving such rapid adoption? The convenience benefits for everyday users are obvious — witness the mobile boom in banking and payments, travel or event ticketing, transport, food delivery and countless more areas of modern life. Access control is a natural fit. If you have your phone, you are already carrying your keys: What could be easier? IBM forecasts that 1.87 billion people globally will be mobile workers by 2022 Less often discussed are the ways mobile management makes life easier for facility and security managers, too. Among those polled for the new Wireless Access Control Report, almost half (47%) agreed that ‘Mobile was more flexible than physical credentials, and 36% believe that mobile credentials make it easier to upgrade employee access rights at any time.’ IBM forecasts that 1.87 billion people globally will be mobile workers by 2022. Workers in every impacted sector require solutions which can get the job done from anywhere: Access management via smartphone offers this. Site management device The smartphone is also convenient for gathering system insights. For example, one new reporting and analytics tool for CLIQ key-based access control systems uses an app to collect, visualise and evaluate access data. Security system data could contribute to business success. The app’s clear, visual layout helps managers to instantly spot relevant trends, anomalies or patterns. It’s simple to export, to share insights across the business. Reinvented for learning — not just as a ‘key’ or site management device — the phone will help businesses make smarter, data-informed decisions. The smartphone will also play a major role in security — and everything else — for an exciting new generation of smart buildings. These buildings will derive their intelligence from interoperability. Over 90% of the report’s survey respondents highlighted the importance of integration across building functions including access control, CCTV, alarm and visitor management systems. Genuinely seamless integration They offer greater peace of mind than proprietary solutions which ‘lock you in’ for the long term Yet in practice, stumbling blocks remain on the road to deeper, genuinely seamless integration. More than a quarter of those polled felt held back by a lack of solutions developed to open standards. ‘Open standards are key for the momentum behind the shift towards system integration,’ notes the Report. As well as being more flexible, open solutions are better futureproofed. Shared standards ensure investments can be made today with confidence that hardware and firmware may be built on seamlessly in the future. They offer greater peace of mind than proprietary solutions which ‘lock you in’ for the long term. Open solutions and mobile management are critical to achieving the goals which end-users in every vertical are chasing: scalability, flexibility, sustainability, cost-efficiency and convenience.
