Recently contacted by your credit card company because of a data breach or were you a victim of identity theft?  Many of us have either been affected by identity theft or know someone who has been affected. Many consumers are seeking a secure environment that is also user-friendly. Businesses are seeking the same, with absolute certainty, that only valid users can access critical data. How can your company tackle these security and usability requirements while ensuring customer satisfaction?

Today's three primary biometric modalities are fingerprint, facial and iris, and each has its own strengths and weaknesses but due to the global COVID-19 pandemic, touchless is highly preferred. Any company claiming their technology is best for all applications is likely being disingenuous. The key is to first prove a biometric is required, and once decided, the following five steps will help select the best biometric modality and supplier.

Today's three primary biometric modalities are fingerprint, facial and iris, and each has its own strengths and weaknessesBiometrics can provide a mechanism to tackle these issues head-on by moving from what you know (password) and have (ID card) to who you are (your biometric), which dramatically increases the level of security while also being user-friendly. But how is the best biometric modality selected for an upcoming product?

User interaction

Start by defining the planned customer usage model, including the typical user, normal or desired interaction, and product in-field environment and placement, as well as any strategic plans. Think through the clothing the users will wear (e.g., face masks), the height of the users, hygiene requirements and opt-in requirements. Decide how quickly the biometric must respond and test this during the POC testing. The better the enrollment image (template), the better the matching performance and overall user experience.

Biometric storage

Decide how quickly the biometric must respond and test this during the POC testing. The better the enrollment image (template), the better the matching performance and overall user experience.

Cost and security

Start by selecting which product lines will use the biometric and establishing the desired price point(s). Decide how the biometric will fit into the product and get bulk pricing to understand unit costs at volume. Software is typically handled as a license fee and often negotiable. The production cost per unit decreases as volumes increase. Choose the biometric modality that best meets functional and security requirements while hitting the targeted price.

The biometric security level required depends on the assets being protected and the matching usage model. A 1:1 model, such as a cellphone, may be fine with a low-security biometric application. However, in a 1:N model, such as airport security, requires a more secure biometric such as iris.

To select the best biometric for the product, compare each company's false acceptance rate (FAR) and false rejection rate (FRR). FAR indicates the biometrics ability to keep intruders out, while FRR indicates the biometrics ability to allow enrolled users in. Ensure that all biometric companies being considered can provide this information at a minimum. It is better to get each company's detection error trade-off (DET) curve, which shows how FAR and FRR vary relative to each other.

Criminal activity

Hackers and criminals are always trying to break technology, including biometrics. Be certain each technology has robust presentation attack detection (PAD), which ideally is third-party certified. Understand what if any personally identifiable information (PII) needs to be captured, and decide how the PII will be handled, including who will manage the data (i.e., your company, the biometric supplier or another third party). Be certain that whoever controls the PII uses the latest encryption standards and employs techniques to secure this data in memory, crossing the network and in the biometric database. Understanding the European GDPR Compliance standards if applicable will also be important.

Supplier consideration

Each supplier being considered should be evaluated throughout the POC testing process. Ensure the supplier is trustworthy, provides good customer support and meets its commitments. Evaluate the supplier's engineering capability and support model to ensure it can support any desired design changes and support your Be certain each technology has robust presentation attack detection (PAD)engineers to deliver the best functioning product.

Selecting the best biometric for your exact use case will take some time and effort, but it has the potential to grow your business and delight your customers. Do not shortchange the process and go with the cheapest solution without doing some research. As the saying goes, you get what you pay for.

How smart technology is simplifying safety and security in retirement villages
How smart technology is simplifying safety and security in retirement villages

James Twigg is the Managing Director of Total Integrated Solutions (TIS), an independent life safety, security and communication systems integrator, specialising in design & consultancy, technology and regulatory compliance. Total Integrated Solutions work primarily with retirement villages, helping to ensure the safety of residents in numerous retirement villages across the country. In this opinion piece, James shares how smart technology is helping security teams and care staff alike in ensuring the safety and security of their spaces, amid the COVID-19 pandemic and beyond. Impact of smart technology Smart technology is having an impact on pretty much every aspect of our lives Smart technology is having an impact on pretty much every aspect of our lives. From how we travel, to how we work, to how we run our homes. It’s not unusual to have Alexa waking us up and ordering our groceries or Nest to be regulating the temperature and energy in our homes. And while there’s a popular misconception that people in their later years are allergic to technology, retirement villages and care homes are experiencing significant innovation too. And the result is not only improved quality of life for residents, but also improved safety and security systems for management teams. Switching to converged IP systems I’ve been working in the life safety and security industry for over fifteen years. When I first joined TIS, much of the sector was still very analogue, in terms of the technology being installed and maintained. Slowly but surely, we’ve been consulting and advising customers on how to design, install and maintain converged IP systems that all talk to each other and work in tandem. I'm excited to say retirement villages are some of the top spaces leading the way, in terms of technological advancement. Improving the quality of life for residents A move into a retirement village can be daunting and one of the key concerns that we hear about is the loss of independence. No one wants to feel like they are being monitored or to have someone constantly hovering over them. One of the ways we’ve used smart technology to maintain residents' independence is through devices, such as health monitors and motion sensors. For example, instead of having a member of staff check-in on residents every morning, to ensure they are well, sensors and analytics can automatically detect changes in routine and alert staff to possible problems. Similarly, wearable tech, such as smart watches give residents a chance to let staff know they are okay, without having to tell them face-to-face. As our retirement village customers have told us, a simple ‘I’m okay’ command can be the difference between someone feeling independent versus someone feeling monitored. Simplifying and improving security systems Smart technology gives care staff and security oversight of the needs of residents For the teams responsible for the safety of the people, places and spaces within retirement villages, smart technology is helping to improve and simplify their jobs. Smart technology gives care staff and security oversight of the needs of residents, and ensures rapid response if notified by an emergency alert, ensuring they know the exact location of the resident in need. And without the need to go and physically check-in on every resident, staff and management can ensure staff time is being used effectively. Resources can be distributed where they are needed to ensure the safety and wellbeing of those residents who need extra consideration. 24/7 surveillance When planning the safety and security for retirement villages, and other residential spaces, it’s no use having traditional systems that only work effectively for 12 hours a day or need to update during the evening. Surveillance needs to be 24/7 and smart technology allows that without the physical intrusion into people’s spaces and daily lives. Smart technology ensures that systems speak to each other and are easily and effectively managed on one integrated system. This includes video surveillance, which has also become much more effective as a result of advanced video analytics, which automatically warn staff of suspicious behaviour. Securing spaces amid COVID-19 This year has, of course, brought new challenges for safety. COVID-19 hit the retirement and residential care sectors hard, first with the initial wave of infections in mid-2020 and then, with the subsequent loneliness caused by the necessary separation of families. As essential workers, we worked closely with our customers to make sure they had everything they needed As essential workers, we worked closely with our customers to make sure they had everything they needed during this time, equipping residents with tablet devices to ensure they could stay connected with their families and friends. It allowed residents to keep in touch without risking transferring the virus. Thermal cameras and mask detection And now that we’re emerging out of COVID-19 restrictions and most residents can see their families again, we’re installing systems like thermal cameras and mask detection, so as to ensure that security will be alerted to anyone in the space experiencing a high temperature or not wearing proper PPE. Such steps give staff and families alike, the peace-of-mind that operational teams will be alerted at the earliest possible moment, should a COVID-19 risk appear. Thinking ahead to the next fifteen years, I’m excited at the prospect of further technological advancements in this space. Because at the end of the day, it’s not about how complex your security system is or how you compete in the industry. It’s about helping teams to protect the people, spaces and places that matter. I see smart technology playing a huge role in that for years to come.

ASSA ABLOY’s Code Handle protects Fylab physiotherapy practice with secure PIN-operated handles
ASSA ABLOY’s Code Handle protects Fylab physiotherapy practice with secure PIN-operated handles

In all medical settings, people are coming and going all day. Therapists leave their personal belongings in changing rooms, patients want privacy in consulting rooms, open or unlocked doors can be an invitation to opportunists. Yet keeping track of mechanical keys can be a tiresome task for a small practice. There is a solution: the Code Handle PIN lock from ASSA ABLOY. In Irun, in Spain’s Basque country, Fylab sought easy electronic door security for their consulting rooms. These rooms house expensive specialist equipment for the various therapeutic disciplines offered by Fylab. Requirements were straightforward: a simple, secure, keyless access solution designed to work in a facility that gets a lot of daily traffic from professionals and the public. They needed a locking device that is easy to retrofit and incorporates a contemporary device design to match with Fylab’s modern medical workplace. Adding electronic security to room doors The Code Handle PIN-locking door handle added electronic security to three consulting-room doors at FylabThe Code Handle PIN-locking door handle added electronic security to three consulting-room doors at Fylab – without wires or cables. Two screws fit a Code Handle to almost any interior door (between 35mm to 80mm thick). One doesn’t even need to change their existing door cylinder. “I am no artist or handyman, but I managed to fit the handles within 10 minutes,” says Fylab founder, Borja Saldias Retegui. Code Handle adds electronic security to almost any interior door without disrupting its aesthetics. If one needs to secure a door facing a public space, Code Handle does it subtly and with zero hassle. At Fylab, Code Handle devices locks both wooden and glass doors, keeping equipment and therapists’ personal belongings safe. Allows up to 9 different PIN numbers “We like the solution a lot because we can do away with keys,” adds Borja. Code Handle removes the need to track cumbersome keys or install expensive access control. Because every Code Handle allows up to 9 different PIN numbers (4 to 6 digits), all authorised staff at Fylab can have their own security code. Two standard batteries (CR2) slot inside the handle, typically lasting 30,000 lock/unlock cycles before replacement The practice manager cancels or amends PINs at any time using the master PIN. Two standard batteries (CR2) slot inside the handle, typically lasting 30,000 lock/unlock cycles before replacement. It’s simple. “Code Handle is unique in comparison to common code door locks: it has the code function and battery incorporated inside its handle, so you don’t need to make extra modifications to your door,” explains Lars Angelin, Business Development Manager for Code Handle at ASSA ABLOY EMEA. Auto-locking feature of Code Handle Auto-locking is another helpful feature. When the door closes, Code Handle locks it automatically. One doesn’t need to put down whatever they are carrying, and no one can open it from the outside while they are not looking. To keep the door open briefly, one can simply hold Code Handle down for 5 seconds and it remains temporarily unlocked. For convenience, Code Handle always opens freely from the inside. “Code Handle provides the simplest solution for access control in a small facility,” says Borja.

What are the challenges and benefits of mobile access control?
What are the challenges and benefits of mobile access control?

There is a broad appeal to the idea of using a smartphone or wearable device as a credential for physical access control systems. Smartphones already perform a range of tasks that extend beyond making a phone call. Shouldn’t opening the door at a workplace be among them? It’s a simple idea, but there are obstacles for the industry to get there from here. We asked this week’s Expert Panel Roundtable: What are the challenges and benefits of mobile access control solutions?
