While the application of facial recognition within both public and private spheres continues to draw criticism from those who see it as a threat to civil rights, this technology has become extremely commonplace in the lives of iPhone users. It is so prevalent, in fact, that by 2024 it is predicted that 90% of smartphones will use biometric facial recognition hardware.

CCTV surveillance cameras 

Similarly, CCTV is a well-established security measure that many of us are familiar with, whether through spotting images displayed on screens in shops, hotels and offices, or noticing cameras on the side of buildings. It is therefore necessary we ask the question of why, when facial recognition is integrated with security surveillance technology, does it become such a source of contention?

It is not uncommon for concerns to be voiced against innovation. History has taught us that it is human nature to fear the unknown, especially if it seems that it may change life as we know it. Yet technology is an ever-changing, progressive part of the 21st century and it is important we start to shift the narrative away from privacy threats, to the force for good that LFR (Live Facial Recognition) represents.

Live Facial Recognition (LFR)

We understand the arguments from those that fear the ethics of AI and the data collection within facial recognition

Across recent weeks, we have seen pleas from UK organisations to allow better police access to facial recognition technology in order to fight crime. In the US, there are reports that LAPD is the latest police force to be properly regulating its use of facial recognition to aid criminal investigations, which is certainly a step in the right direction. While it is understandable that society fears technology that they do not yet understand, this lack of knowledge is exactly why the narrative needs to shift.

We understand the arguments from those that fear the ethics of AI and the data collection within facial recognition, we respect these anxieties. However, it is time to level the playing field of the facial recognition debate and communicate the plethora of benefits it offers society.

Facial recognition technology - A force for good

Facial recognition technology has already reached such a level of maturity and sophistication that there are huge opportunities for it to be leveraged as a force for good in real-world scenarios. As well as making society safer and more secure, I would go as far to say that LFR is able to save lives.

One usage that could have a dramatic effect on reducing stress in people with mental conditions is the ability for facial recognition to identify those with Alzheimer’s. If an older individual is seemingly confused, lost or distressed, cameras could alert local medical centres or police stations of their identity, condition and where they need to go (a home address or a next of kin contact).

Granted, this usage would be one that does incorporate a fair bit of personal data, although this information would only be gathered with consent from each individual. Vulnerable people could volunteer their personal data to local watchlists in order to ensure their safety when out in society, as well as to allow quicker resolutions of typically stressful situations.

Tracking and finding missing persons

Another possibility for real world positives to be drawn from facial recognition is to leverage the technology to help track or find missing persons, a lost child for instance. The most advanced forms of LFR in the market are now able to recognise individuals even if up to 50% of their face is covered and from challenging or oblique angles.

Therefore, there is a significant opportunity not only to return people home safely, more quickly, but also reduce police hours spent on analysing CCTV footage.

Rapid scanning of images

Facial recognition technology can rapidly scan images for a potential match

Facial recognition technology can rapidly scan images for a potential match, as a more reliable and less time-consuming option than the human alternative. Freed-up officers could also then work more proactively on the ground, patrolling their local areas and increasing community safety and security twofold.

It is important to understand that these facial recognition solutions should not be applied to every criminal case, and the technology must be used responsibly. However, these opportunities to use LFR as force for good are undeniable.  

Debunking the myths

One of the central concerns around LFR is the breach of privacy that is associated with ‘watchlists’. There is a common misconception, however, that the data of every individual that passes a camera is processed and then stored. The reality is that watch lists are compiled with focus on known criminals, while the general public can continue life as normal.

The very best facial recognition will effectively view a stream of blurred faces, until it detects one that it has been programmed to recognise. For example, an individual that has previously shoplifted from a local supermarket may have their biometric data stored, so when they return to that location the employees are alerted to a risk of further crimes being committed.

Considering that the cost of crime prevention to retailers in recent years has been around £1 billion, which therefore impacts consumer prices and employee wages, security measures to tackle this issue are very much in the public interest. Most importantly, the average citizen has no need to fear being ‘followed’ by LFR cameras. If data is stored, it is for a maximum of 0.6 seconds before being deleted.


Privacy is ingrained in facial recognition solutions, yet it seems the debate often ignores this side of the story

Privacy is ingrained in facial recognition solutions, yet it seems the debate often ignores this side of the story. It is essential we spend more time and effort communicating exactly why watchlists are made, who they are made for and how they are being used, if we want to de-bunk myths and change the narrative.

As science and technology professionals, heading up this exciting innovation, we must put transparency and accountability at the centre of what we do. Tony Porter, former Surveillance Camera Commissioner and current CPO at Corsight AI, has previously worked on developing processes that audit and review watch lists. Such restrictions are imperative in order for AI and LFR to be used legally, as well as ethically and responsibly.

Biometrics, mask detection and contactless payments

Nevertheless, the risks do not outweigh the benefits. Facial recognition should and can be used for good in so many more ways than listed above, including biometric, contactless payments, detecting whether an individual is wearing a facemask and is therefore, safe to enter a building, identifying a domestic abuse perpetrator returning to the scene of a crime and alerting police.

There are even opportunities for good that we have not thought of yet. It is therefore not only a waste not to use this technology where we can, prioritising making society a safer place, it is immoral to stand by and let crimes continue while we have effective, reliable mitigation solutions.

Smart Offices: How is mobile ID changing the way we access the office?
Smart Offices: How is mobile ID changing the way we access the office?

If you’re a security or facilities manager, you may already be aware of the quiet revolution that’s taking place across businesses and organisations up and down the country. By the end of 2020, 20% of all ID and access control systems featured mobile capability, and this is set to increase by a further 34% over the next three years. There’s no doubt that using a smartphone or mobile device in place of traditional credential and access control is a growing trend that’s only been sped up by the pandemic. It’s true that many businesses are still very much focused on remote working, although many are now starting to implement new-and-improved strategies that are better suited to protect the workforce moving forward. Mobile ID systems As the next normal becomes clearer, businesses will be reviewing procedures such as access control, occupancy monitoring, reducing touch points and tracking visitors. Mobile ID systems are ideally suited to this task. But what are the key reasons for considering such a setup in 2021? But why is this new technology so well-suited to future-proof your physical access system, and why is it becoming so popular? Eradicating outdated legacy credentials Have you seen just how vulnerable outdated Proximity card technology can be? Low-frequency 125kHz cards can be cloned in a matter of seconds with the use of cheap, readily available tools. Despite their weaknesses, they are still used by a huge majority of businesses – big and small. All smartphones include two industry-standard features that make them perfect for operating a secure, contactless credential Replacing such a system with a mobile-enabled system is one of the best ways to increase security ten-fold. Thanks to a cloud-based infrastructure, mobile ID offers best-in-class security and cryptography. All smartphones include two industry-standard features that make them perfect for operating a secure, contactless credential. Bluetooth Smart and NFC (Near Field Communication) make them the best product to operate such a credential via a secure app. If you’re looking for best-in-class security in 2021, mobile access is most definitely the way forward. Removing touch points across the business Reducing touch points and the adoption of touchless facilities has become a key priority for businesses in the wake of COVID-19. Even as businesses start to return to the office and operate a home/office split, it will be imperative that unnecessary contact is kept to an absolute minimum between staff. The traditional issuance of identification and access control credentials can pose problems in this regard. Facility and security managers who are responsible for onboarding and processing ID have done the process face to face. Mobile access makes it possible to carry this process out without people coming into direct content. First, the security manager has access to a secure portal, allowing them to create, manage and edit credentials anywhere. They can upload and remotely transfer mobile ID and access control credentials directly to users’ smartphones over the air. Via the secure app, users can view and see their credentials and immediately begin using it for ID and access control by simply placing their smartphone over card readers. Enabling a more flexible way of working The way in which we work has changed for good. Even as people more people return to the office in 2021, a majority of businesses will be operating a home/office split indefinitely. This once again reinforces the need for a smarter, more adaptable onboarding system. Implementing mobile ID is the perfect way of doing this: over-the-air delivery of credentials and security data is now a given, helping businesses create the perfect balance between the home and the office. No longer do people have to come into the office for the onboarding process. Increasing convenience and user experience More often businesses are realising the value mobile ID can have for enhancing the work experience as well as security Ok, so mobile ID is the perfect way of increasing security and adapting workplaces to a post-COVID way of working. And we’ve not even touched on the most obvious advantage yet: Convenience. How many times have you forgotten your ID card? We’re sure it’s more times than you forget your smartphone. These powerful processors have become intertwined with the way we carry out tasks on a daily basis. They’re so vital that people will soon notice if they’ve forgotten it. From an employee’s perspective, mobile ID and access control is simple, convenient and extremely user-friendly. More and more businesses are realising the value mobile ID can have for enhancing the work experience as well as security. From the employer’s perspective, mobile ID means it’s easier for administrators to manage access and credentials. Future-proofing access control now will ensure that in the longer term, mobile ID is well worth the investment. The annual expenditure of printing ID cards and purchasing credentials can be vast, while reissuance costs can also quickly add up for larger organisations. These issues are a thing of the past for businesses using mobile ID. Mobile ID perfect tool for 2021 and beyond Until mobile ID, new and improved credentials’ main focus was on increasing security. Mobile ID not only delivers that, but it also provides a more convenient way of accessing the office in a way that’s perfectly suited to returning to the office in 2021. If there was ever a time to upgrade, now is the time. Summing up, mobile access is changing the way we access the office by: Eliminating weak links in security systems such as outdated legacy card technologies Eradicating the need for touch points across multiple areas of the workplace Enabling a smarter, more flexible approach to onboarding Increasing convenience – for both employers and employees.

Remote Monitoring technology: Tackling South Africa’s cable theft problem
Remote Monitoring technology: Tackling South Africa’s cable theft problem

For decades, cable theft has caused disruption to infrastructure across South Africa, and an issue that permeates the whole supply chain. Here, Ian Loudon, international sales and marketing manager at remote monitoring specialist Omniflex, explains how new cable-alarm technology is making life difficult for criminals and giving hope to businesses. In November 2020, Nasdaq reported that, “When South Africa shut large parts of its economy and transport network during its COVID-19 lockdown, organised, sometimes armed, gangs moved into its crumbling stations to steal the valuable copper from the lines. Now, more than two months after that lockdown ended, the commuter rail system, relied on by millions of commuters, is barely operational.” Private security firm Despite this most recent incident, cable theft is not a new phenomenon to sweep South Africa Despite this most recent incident, cable theft is not a new phenomenon to sweep South Africa. In 2001, SABC TV broadcast a story following two members of a private security firm working for Telkom, a major telecoms provider. In the segment, the two guards, working in Amanzimtoti on the south coast of KwaZulu-Natal, head out to investigate a nearby alarm that has been triggered. They reach a telecoms cabinet and discover that it has been compromised, with the copper cable cut and telephone handsets strewn across the ground. In the dark, they continue to search the area when one of the guards discovers the problem: 500 metres of copper wire has been ripped out. In their haste, the thieves have dropped their loot and fled. Widespread cable theft Had they managed to get away, they would have melted the cable to remove the plastic insulation and sold the copper to a local scrap dealer for around 900 Rand, about $50 US dollars. For the company whose infrastructure has been compromised, it may cost ten times that amount to replace and repair the critical infrastructure. The disappointing takeaway from this story is that two decades on from this incident the country still faces widespread cable theft, whether it’s copper cables from mines, pipelines, railways, telecoms or electrical utilities. In fact, the South African Chamber of Commerce and Industry estimates that cable theft costs the economy between R5–7 billion a year. The answer to the problem must go further than the existing measures used by companies. Detect power failure Most businesses already invest in CCTV, fences, barriers and even patrol guards, but this is not enough. Take the mining sector, for example. These sites can be vast, spanning dozens of kilometres - it’s simply not cost effective to install enough fences or employ enough guards or camera operators. As monitoring technology gets better, the company has seen site managers increasingly use cable alarms in recent years that detect when a power failure occurs. The idea is that, if one can detect a power failure, they can detect whether the cable has been cut The idea is that, if one can detect a power failure, they can detect whether the cable has been cut. The problem is though: how does one distinguish the difference between a situation where a cable has been cut intentionally and a genuine power outage? Power outages in South Africa are an ongoing problem, with the country contending with an energy deficit since late 2005, leading to around 6,000 MW of power cuts in 2019. Remote terminal units Eskom Holdings SOC Ltd., the company that generates around 95 per cent of South Africa’s power has already warned of further blackouts as the company works to carry out repairs to its power plants. According to a statement on the company’s website, “Eskom spends in the region of R2 billion a year replacing stolen copper cables." The result is that criminals take advantage of the gaps in power to steal cable, timing their robberies to coincide with the published load shedding schedules. The basic alarms used to detect power outage won’t recognise the theft because they register a false-positive during a power cut. By the time the power comes back on, the deed has been done and the criminals have gotten away with the cable. The good news is that recent breakthroughs in cable monitoring technology are helping tackle just this problem. New alarms on the market now combine sophisticated GSM-based monitoring systems that use battery powered remote terminal units. Legitimate supply chain Unlike the basic alarms that look for the presence or absence of power, these new systems monitor whether the cable circuit is in an open or closed state. In the event of a power outage, the unit continues to run on battery power and can detect if a cable has been cut, sending a priority SMS alert to the site manager immediately, giving them a fighting chance to prevent a robbery in progress. Beyond the opportunistic theft carried out by petty criminals, the theft of copper cables forms a wider problem Beyond the opportunistic theft carried out by petty criminals, the theft of copper cables forms a wider problem across the supply chain in South Africa. In recent years, the combination of unscrupulous scrap dealers, the alleged involvement of large scrap processing companies and lax penalties meant that much of the stolen copper ended up back in the legitimate supply chain. However, recent changes in the law have sought to take a tougher stance on copper theft. Alarm monitoring technology According to the Western Cape Government, “The Criminal Matters Amendment Act, regulates bail and imposes minimum offences for essential infrastructure-related offences." The act, which came into effect in 2018, recommends sentencing for cable theft, with the minimum sentence for first-time offenders being three years and for those who are involved in instigating or causing damage to infrastructure, the maximum sentence is thirty years. It seems to be working too. In January 2021, the South African reported that a Johannesburg man was sentenced to eight years behind bars for cable theft in Turffontein. While the longer-term outlook is a positive one for industry, the best advice for businesses seeking to alleviate the problem of cable theft in the immediate future is to invest in the latest cable-theft alarm monitoring technology to tackle the problem and make life difficult for criminals.

What are the positive and negative effects of COVID-19 to security?
What are the positive and negative effects of COVID-19 to security?

The COVID-19 global pandemic had a life-changing impact on all of us in 2020, including a multi-faceted jolt on the physical security industry. With the benefit of hindsight, we can now see more clearly the exact nature and extent of that impact. And it’s not over yet: The pandemic will continue to be top-of-mind in 2021. We asked this week’s Expert Panel Roundtable: What have been the positive and negative effects of Covid-19 on the physical security industry in 2020? What impact will it have on 2021?
