In real life people usually don’t want to get into the drama of being seen as someone other than themselves. The misrecognition problem is not only time consuming, dignity compromising but also, in lots of cases, life threatening, if certain dangerous people are not correctly identified in time. This mistake is no longer affordable in today’s context, whether for an individual, a group or society as a whole.

Fortunately, the facial recognition technology has matured, and the security solution based on the said technology is being widely used across the world. Dahua Technology, a premier solution provider in the global surveillance industry, is especially good in this realm as has been proved by multiple championship and new records in major international challenges, including Multiple Object Tracking Challenge, the KITTI 2D Object Detection Evaluation 2012, KITTI Flow Benchmark, Task [Word Recognition] of Incidental Scene Text Challenge and Born-Digital Image Challenge.

A Smart AI algorithm optimises the image captured in multiple angles or blurred in motion and translates the face feature into a digital model

Dahua facial recognition

It is necessary to explain some basic rules concerning how facial recognition works before the tour to see how Dahua Technology’s products & solutions are applied in various daily scenes. Simply put, big data is useless if the accuracy and efficiency of facial recognition has not been improved to a certain level. The face detection, whether from a snapshot or from a stream of video, requires not only a high-quality camera but more importantly, a smart AI algorithm that optimises the image captured in multiple angles or blurred in motion and translates the face feature into a digital model which can be crosschecked in the database. The whole process, from taking the picture to comparison, takes as short as 300ms.

Suppose there's Tom, a middle level manager in his mid-30s. Let’s follow Tom for a day and see how Dahua Technology’s facial recognition solution plays its role in his perfectly ordinary life.

Building security system

Tom hurried to his company on the 30th floor of a class A office building, the kind with additional barriers in the lobby between the front gate and elevators. There were long lines in front of the access control machines. Tom reached into his pocket and found unfortunately his access card wasn't there.

But Tom should worry no more because the building had just updated the security system with Dahua’s facial recognition solution, which overcame various shortcomings of traditional ways of card or fingerprint scanning, including low efficiency and inadequate security. Compared to a card, apparently it is much less likely for one to lose/replicate/borrow a face. And the access control was no longer a gamble if one's fingerprint works.

The powerful cameras with deep learning AI, detect the faces and digitalise the features and compare them purely through numbers

Deep learning AI detection

Here’s exactly how Dahua’s facial recognition solution works in this scene. The powerful cameras blessed with deep learning AI, detect the faces and digitalise the features and compare them purely through numbers with the ones in the database which takes less than 1 second. The beauty of the solution goes both ways since the company no longer needs to make a card or import finger prints for the newly employed but simply upload their photos into the database that contains up to 10,000 faces.

Besides offices, this solution can also be applied to any place that has a high standard for access control, like customs, schools, residential communities, etc.

Smart access solution

Tom stepped into a bank. On behalf of his company, Tom had some serious business to discuss with the bank, which, at this hour, was full of people. And before Tom started to worry about the time to be spent waiting and if he could make it to the next meeting on time, he heard his last name called and was led into the VIP room.

Now how did the bank manage do that? Not by human efforts for sure. No clerk could remember each and every face and match it with a particular name and particular business without making any mistake. That’s why a facial recognition solution is essential to the business. The immediate detection of a VIP face could be easily matched with the white list in the database. No delay or misidentification and all VIP treatment.

This goes not only for banks. Hotels, hospitals and casinos alike will also benefit from this solution that secures the proper respect those exceptional customers deserve.

Preventing unauthorised access

Tom went to the vault of the bank for the first time in his life. He was happy that now he was trusted by the company with such important mission. He walked fast and went in front of the escort. But before he could raise his hand to touch the door of the vault, a warning siren was triggered. The escort, with a reassuring smile, caught up and patted on Tom's shoulder and explained the whole situation to him.

No unauthorised personnel could intrude the sensitive areas blessed with Dahua’s facial recognition solution

No unauthorised personnel, be it Tom or Jerry, could intrude the sensitive areas blessed with Dahua’s facial recognition solution. The face captured and automatically optimised by the camera would be put into real time comparison with the authorised faces in the data base and the low percentage of similarity, from a pure mathematical point of view, would immediately trigger the alarm.

Other limited access areas like labs and archives will also enjoy better protection with this facial recognition solution.

Security identification management

After a long day’s work, Tom went to see a football game with a friend. The show began even before they entered the stadium because they saw an infamous football hooligan got rejected and taken away outside the entrance gate. Tom, who had been through plenty of adventures during the day, kind of figured out what happened. And Tom’s friend, who happened to be an employee of Dahua Technology, took the chance to explain how Dahua’s facial recognition solution informed the security force to deal with any persona non grata on the black list as soon as they showed their faces.

Of course, this solution could be widely applied to other areas like airports, train stations, or in other words, city management.

So, this was a day in Tom’s life, which was endowed with some dramatic coincidence but totally realistic in every scene. These examples were far from exhaustion of all the possible applications of Dahua facial recognition solution that fully activates big data gathered and thus spawns a great many creative applications in terms of security and business, resulting indeed into a Safer Society and Smarter Living, as has always been envisioned by Dahua Technology.

Enhance traditional security systems within your smart home
Enhance traditional security systems within your smart home

Market dynamics are changing the U.S. residential security market, creating new business models that better appeal to the approximately 70% of households without a security system. Smart home adjacencies have helped revitalise the traditional security industry, and alternative approaches to systems and monitoring for the security industry are emerging, including a new batch of DIY systems. Growth in the residential security market and its position as the channel for smart home solutions have attracted numerous new entrants. Telecoms, cable operators, and CE (consumer electronics) manufacturers are joining traditional security players as they compete to fulfill consumer demand for safety and security. Connected products also provide a layer of competition as consumers must decide whether having category devices such as doorbell video cameras, networked cameras, and other products suffice for their security. Increasingly competitive landscape Smart home services can provide additional revenue streams for the security industry For instance, IP cameras are a highly popular smart home device rooted in security, and Parks Associates estimates 7.7 million standalone and all-in-one networked/IP cameras will be sold in the U.S. in 2018, with $889M in revenues. Product owners may feel their security needs are fulfilled with this single purchase, as such dealers and service providers are under increasing pressure to communicate their value proposition to consumers. Categorically, each type of player is facing competition uniquely—national, regional, and local dealers all have a different strategy for overcoming the increasingly competitive landscape. Smart home services can provide additional revenue streams for the security industry. In Parks Associates’ 2017 survey of U.S. security dealers, 58% report that smart home service capabilities enable extra monthly revenue. Almost half of dealers also note they have to offer smart home devices and services in order to keep up with their competition. While white-label devices are acceptable in some instances, dealers need to integrate with hero products whenever possible when those exist for a category. For dealers who have added smart home devices and services are all potential benefits and good for business Improved customer engagement That 2017 survey also revealed 36% of security dealers that offer interactive services report security system sales with a networked camera and 16% report sales with a smart thermostat. For dealers who have added smart home devices and services, enhanced system utility, increased daily value, and improved customer engagement with the system are all potential benefits and good for business. Security has served as the most productive channel for smart home solutions, mainly because the products create natural extensions of a security system’s functions and benefits, but as smart home devices, subsystems, and controllers expand their functionality, availability, and DIY capabilities, many standalone devices constitute competition to classical security. Particularly viable substitute devices include IP cameras, smart door locks, smart garage doors, or a combination of these devices. Products that are self-installed offer both convenience and cost savings, and these drivers are significant among DIY consumers—among the 6% of broadband households that installed a security system themselves, 39% did it to save money. Enhance traditional security Self-installable smart home devices may resonate with a segment of the market who want security While many security dealers believe substitute offerings are a threat, some dealers do not find such devices an existential threat but instead view them as another path to consumer awareness. They argue that the difference between smart product substitutes and traditional security is that of a solution that provides knowledge versus a system that gives one the ability to act on that knowledge. A common theme among professional monitoring providers is that a homeowner who is aware of events happening in the home does not necessarily have a secure and protected household. For example, a Nest camera, a DIY product, notifies a consumer via smartphone about events in the home when it detects motion, but only when the notification is opened and identified will a consumer be able to act on the related event. Self-installable smart home devices may resonate with a segment of the market who want security but are unwilling to adopt professional monitoring; however, providers can leverage these devices to enhance traditional security features and communicate the value of professional monitoring. Smart home devices and features, while posing a threat to some security companies, are a potential way forward to increased market growth Increased market growth A key counterstrategy for security dealers and companies is to leverage their current, powerful role as the prime channel for smart home devices. Many security dealers now include smart home devices with their security systems to complement their offerings and increase system engagement. For example, as of Q4 2017, nearly 70% of U.S. broadband households that were very likely to purchase a security system in the next 12 months reported that they want a camera to be included as part of their security system purchase. In response, many security system providers now offer IP cameras as optional enhancements for their systems. Smart home devices and features, while posing a threat to some security companies, are a potential way forward to increased market growth. Security dealers have an opportunity to become more than a security provider but a smart home solutions provider rooted in safety. Provide status updates Comcast has entered both the professionally monitored security market and the market for smart home services The alternative is to position as a provider of basic security with low price as the key differentiator. Comcast has entered both the professionally monitored security market and the market for smart home services independent of security. It has discovered that monetising smart home value propositions through recurring revenue becomes increasingly challenging as the value extends further away from life safety. Since the security industry remains the main channel for smart home services, security dealers are in a unique position to leverage that strength. Value propositions must shift from the traditional arming and disarming of a system to peace-of-mind experiences that builds off the benefits of smart devices in the home to provide status updates (e.g., if the kids arrived home safely) and monitoring at will (e.g., checking home status at any time to see a pet or monitor a package delivery). These types of clear value propositions and compelling use cases, which resonate with consumer and motivate them to expand beyond standalone products, will help expand the home security market.

What is the value of "free" video management systems?
What is the value of "free" video management systems?

They say that every choice has a cost. It's a basic principle that, economically speaking, nothing is free. If it doesn't cost actual money, it may be expensive in terms of time, attention and/or effort. These are interesting observations to keep in mind as one peruses the various "free" video management system (VMS) offerings available on the market. Some are provided by camera companies to unify their products into a "system", even if it's a small one. Other free VMS offerings are entry-level versions offered by software companies with the intent of the customer upgrading later to a paid version. For more insights, we asked this week's Expert Panel Roundtable: What is the value of “free” video management systems (VMSs) and how can a customer decide whether “free” is the right price for them?

The ongoing challenge of IT and data risk management
The ongoing challenge of IT and data risk management

Managing IT and data risk is a challenging job. When we outsource our IT, applications and data processing to third-parties more and more every day, managing that risk becomes almost impossible. No longer are our data and systems contained within an infrastructure that we have full control over. We now give vendors our data, and allow them to conduct operations on our behalf.  The problem is, we don’t control their infrastructure, and we can never fully look under the hood to understand and vet their ability to protect our data and operations. We have to fully understand how important this issue is, and ensure we have the right governance, processes and teams to identify and mitigate any risks found in our vendors. No longer are our data and systems contained within an infrastructure that we have full control over Today, everything is connected. Our own networks have Internet of Things (IoT) devices.  We have VPN connections coming in, and we aren’t always sure who is on the other end of that connection. It is a full-time job just to get a handle on our own risk. How much harder, and how much larger should our teams and budgets be, to truly know and trust that our vendors can secure those devices and external connections?  For every device and application we have internally, it is very difficult to even keep an accurate inventory. Do all of our vendors have some special sauce that allows them to overcome the traditional challenges of securing internal and vendor-connected networks? They are doing the same thing we are – doing our best with the limited human and financial resources allocated by our organisation. Risk stratification and control objectives  The benefits of outsourcing operations or using a vendor web application are clear. So how can we properly vet those vendors from an IT risk perspective?  The very first thing we need to put in place is Risk Stratification. Risk Stratification presents a few targeted questions in the purchasing process. These questions include – what type of data will be shared? How much of this data? Will the data be hosted by a vendor? Will this hosting be in the US or offshored? Has the vendor ever had a data breach? These questions allow you to quickly discern if a risk assessment is needed and if so, what depth and breadth.  Risk stratification allows you to make decisions that not only improve your team’s efficiency, but also ensure that you are not being a roadblock to the business Risk stratification allows you to make decisions that not only improve your team’s efficiency, but also ensure that you are not being a roadblock to the business. With risk stratification, you can justify the extra time needed to properly assess a vendor’s security.  And in the assessment of a vendor’s security, we have to consider what control objectives we will use. Control objectives are access controls, policies, encryption, etc. In healthcare, we often use the HITRUST set of control objectives. In assessing against those control objectives, we usually use a spreadsheet.  Today, there are many vendors who will sell us more automated ways to get that risk assessment completed, without passing spreadsheets back and forth. These solutions are great if you can get the additional budget approved.  Multi-factor authentication  Even if we are using old-fashioned spreadsheets, we can ensure that the questions asked of the vendor include a data flow and network/security architecture document.  We want to see the SOC2 report if they are hosting their solution in Amazon, etc. If they are hosting it within their own datacentre, we absolutely want to see a SOC2 Type II report. If they haven’t done that due diligence, should that be a risk for you?  Today, we really need to be requiring our vendors to have multi-factor authentication on both their Internet-facing access, as well as their privileged internal access to our sensitive data. I rate those vendors who do not have this control in place as a high risk. We’ve recently seen breaches that were able to happen because the company did not require administrators or DBAs to use a 2-factor authentication into sensitive customer data sources.  In the assessment of a vendor’s security, one has to consider what control objectives to use This situation brings up the issue of risk acceptance. Who in your organisation can accept a high risk? Are you simply doing qualitative risk assessment – high, medium and low risks? Or are you doing true quantitative risk analysis? The latter involves actually quantifying those risks in terms of likelihood and impact of a risk manifesting, and the dollar amount that could impact your organisation.   So is it a million dollars of risk? Who can accept that level of risk? Just the CEO? These are questions we need to entertain in our risk management programs, and socialised within your organisation.  This issue is so important – once we institute risk acceptance, our organisation suddenly starts caring about the vendors and applications we’re looking to engage.  If they are asked to accept a risk without some sort of mitigation, they suddenly care and think about that when they are vetting future outsourced solutions. Quantitative risk analysis involves quantifying risks in terms of likelihood and impact of a risk manifesting Risk management process  In this discussion, it is important to understand how we think of, and present, the gaps we identify in our risk management processes. A gap is not a risk. If I leave my front door unlocked, is that a control gap or a risk? It is a gap – an unlocked door. What is the risk?  The risk is the loss of property due to a burglary or the loss of life due to a violent criminal who got in because the door was unlocked. When we present risks, we can’t say the vendor doesn’t encrypt data. The risk of the lack of encryption is fines, loss of reputation, etc. due to the breach of data. A gap is not a risk.  Once we’ve conducted our risk analysis, we must then ensure that our contracts protect our organisation? If we’re in healthcare, we must determine if the vendor is, in fact, a true HIPAA Business Associate, and if so we get a Business Associate Agreement (BAA) in place. I also require my organisation to attach an IT Security Amendment to these contracts. The IT Security Amendment spells out those control objectives, and requires each vendor to sign off on those critical controls. We are responsible for protecting our organisation’s IT and data infrastructure – today that often means assessing a 3rd-party’s security controls One final note on risk assessments – we need to tier our vendors. We tier them in different ways – in healthcare a Tier 1 vendor is a vendor who will have our patient information on the Internet. Tiering allows us to subject our vendors to re-assessment. A tier 1 vendor should be re-assessed annually, and may require an actual onsite assessment vs. a desk audit. A tier 2 vendor is re-assessed every 2 years, etc. We are responsible for protecting our organisation’s IT and data infrastructure – today that often means assessing a 3rd-party’s security controls. We must be able to fully assess our vendors while not getting in the way of the business, which needs to ensure proper operations, financial productivity and customer satisfaction. If we truly understand our challenge of vendor risk management, we can tailor our operations to assess at the level needed, identify and report on risks, and follow-up on any risks that needed mitigated.
