Behind the Curtains of Facial Recognition Technology



Facial Recognition Technology

Technology has promised to make our lives better, and it has done so in numerous
ways too. That said, there is always a grey area associated with it. Facial recognition is often considered to be a technology in this category.

Having been around for a while now, there have been cases for and against it. If there is any time to discuss where the court of public opinion should sway regarding facial recognition controversies, it is now.

What is Facial Recognition Technology?

Facial recognition is not just the technology that allows you to unlock your iPhone X series or other new-generation devices. To properly understand what we are dealing with, we also have to know what facial recognition tech is in its basic form.

Here, we can simply define facial recognition as the technology that helps with the identification and verification of people via the biometric information provided by their faces. Like other forms of identification, this system leverages the understanding that the unique setups of the human face are particular to individuals, and can be used to tell them apart from another person.

As humans, we have the innate ability to recognize people and faces too. When we see someone that we know, there are a lot of processes going on in our brain, but they happen in split seconds to bring about remembrance and recognition.

That is the model which facial recognition tech from all over the world has copied to replicate the results it can generate on a massive scale.

So, how do these systems work?

  • A capture of the target’s face is completed to serve as raw data. This face might be captured in isolation or a group/ crowd of people
  • The facial recognition algorithms map all the features of the faces so that it can ‘remember’ it. These features include but are not limited to, the geometry of the face, the distance between the eyes, the length between the forehead and chin, special features on the face, etc.
  • From the mathematical data generated above, a facial signature is created for the target. This is unique to them unless there is also someone with the same face data (almost impossible).
  • When such a face is run through the system again, the AI uses the data from the supplied face and runs it through all the signatures in the database. A match is made.

That looks simple enough, but it takes a lot of processing power to get it done. The intricacies of the calculations that facial recognition tech also have to make for accuracy has greatly improved in the past few years.

Today, we have commercial-grade facial recognition software – such as the one on the Apple iPhone X series – that is accurate to about 1: 1,000,000 odds of making a mistake.

Where Is Facial Recognition Used?

Like we said in the opening part of this, facial recognition is more than what you just use to unlock your phones. While that use case has drawn more attention to it in the past couple of years, it has been applied in different areas of human life.

Looking around today, some of the common use cases of facial recognition tech include:


Facial Recognition Technology At Airports

Governments, especially in developed countries, have installed different facial recognition systems in airports all around the world.

The US is known for using this to track known and suspected terrorists before they gain entry into, or leave, the country. It has also been employed to fish out travelers and immigrants that have overstayed their welcome in the country, usually having an expired visa or other crimes to their names.

Computer Systems

Mobile phones and computers have also enjoyed the use of a facial recognition system, and we are seeing more and more of such units make the market these days.

This is usually offered as an upgrade over the basic fingerprint biometrics system that we saw first – and it could even come alongside this on some models. Laptop and PC manufacturers are also getting in on this trend, fitting their modules with facial login systems for easier access.

The level of security that these applications provide remains a contended topic, but that will be discussed later.


Facial Recognition Technology At Colleges

Some colleges have started using facial recognition systems for various purposes.

While some keep the applications to putting up better safety and security around the school, others have opted to bring the technology into the classroom too. Here, it can be employed to take roll calls and determine if a student has been missing class. That, it is believed, beats having a student sign the attendance sheets on behalf of another, curbs examination malpractice, etc.


You will be surprised to know that some companies now prefer to have their members of staff access business areas with a facial system rather than ID badges. Likewise, it could also be employed to log the staff member into work, effectively tracking the time that they came in better than non-digital systems can.

Social Media

Social media platforms like Facebook will scan pictures that you upload to identify other users, asking you if you want to tag them in the post. This happens so fast that you don’t even know when they had the time to run all the faces that popped up in your picture frame.

Besides these, stores, markets, religious organizations also make use of facial recognition technology to an extent.

Where Facial Recognition Shines

Safety and Security

Observing all that has been said so far, it becomes easy to see that the most widespread use case for facial recognition is for safety and security.

Government agencies do not have the manpower to go combing through crowds of people in different cities just to identify one person. What they can do, though, is turn to facial recognition so that they get alerted as soon as the cameras find a match anywhere.

This allows for the concentration of resources on finding where the hit originated from rather than expending their energy all over the place.

To this effect, facial recognition has proved successful.

Arrests have been made based on data access via such tech, criminals have been identified and the world can be said to be a safer place for that.

Identification of Missing people

Another plus for facial recognition tech on this front is in the identification of missing people. A trial run of a facial recognition platform once helped in the positive matching and spotting of thousands of missing children within mere hours of its deployment. It remains to see if human efforts, without the tech, could have yielded such results in a little time.

Prevent Malpractice at Schools

The facial recognition tech could also help schools to prevent malpractice. It is not unheard of for students to pay someone else to sit for their exams. While these imposters could get through every other kind of check imaginable, they won’t be able to fool the facial recognition software.


While on this matter, the convenience of facial recognition is why many users are flocking towards it. It offers a non-intrusive, contactless method of identifying and verifying people. That is unlike physical checks, fingerprint stops, etc. Thus, there is a convenience that also comes with installing one such system around too.

Speaking of convenience, social giants like Facebook are not the only ones using facial recognition tech to identify you and others in your photos. Look through the main cloud photo storage platforms (think Google Photos and iCloud), and you see how they help you group pictures/ identify contacts based on their facial data.

Prevent Time Frauds

It is not uncommon for employees to come into work late but record earlier times. Sometimes, it is also important within the business to know who accesses what rooms, and at what times. With facial recognition, operations like this become seamless without adding an extra second of wait time.

There are other benefits of facial recognition on smaller scales, depending on where they have been deployed. However, the above have done well to represent the main benefits associated with this form of tech at different times.


Where Facial Recognition Falls Short

For all the good run that facial recognition tech seems to have had, there are serious concerns about it too.

Invasion of Personal privacy

While the government, businesses, store owners and other users in the public space might argue that they are using the tech to regulate crime, they are doing so without consent. Facial data is being collected by these cameras and AI every time, even if you have a sparkling clean record.

In other words, these people are collecting data about you without your consent and permission.

When the government says that it can track down criminals by following their facial data around, they are conveniently not saying that they can track you the same way. After all, the system has not been built to throw an exception when it finds a non-criminal entity.

With such in place, you don’t know how much of what you do is under the watchful eyes of the government and whoever they have put in charge of the systems.

Racial Bias

Racial bias is also something that should be highly considered here.

Some reports have claimed that these facial recognition systems are generally bad at making out people of different races and colors. This same misconception has also been extended to women in diverse ethnic groups. If we are to be honest, there is a bit of truth behind this misconception.

For facial recognition systems to work at their best, they need to be trained with various datasets and faces. In these training modules, so to speak, there is a gross under-representation of people of different races and women.

Such could lead the system to throw a false positive or a false negative. Either way, that might mean disaster for the subject that was not identified, or wrongly identified to be someone else.

Risks of data breach

That might not be an issue in itself until you consider what could happen in a data breach. Since you don’t know how this data is being stored, you have the right to be concerned about where it might end up. After all, your face is yours – but the digital version can be used by just about anyone who gets access to it in a data breach.

Lack of regulations

Perhaps the most dangerous thing concerning this piece of technology is the almost non-existent regulation around it.

Even though the technology is being deployed on a larger scale, who checks how it is being used? What governs how the data is being collected, stored and reproduced? Who draws a line between the white-and-blacks of the facial tech world?

Going Forward

The Future of Facial Recognition
The Future of Facial Recognition

In the closing parts of last year, San Francisco led the charge in becoming the first city to ban the use of facial recognition systems. If there were not strong arguments for this, it would not have happened.

It might be true that they help to analyze threats and neutralize them. However, the grave threats to the privacy and security of peaceful, law-abiding citizens cannot be waived too. If data of any kind is to be collected, including facial information, the least that advocates could do is ask for consent. Facial recognition will not go away. At least, not anytime soon. But then, staying will mean that this tech is ready to conform to regulations which will soon start springing up anyways.

Home Improvement Ideas for 2021



Home Automation Systems

With most people in the world spending vastly more time at home than before, change is inevitable. Spending lots of time at home allows people to examine their surroundings and want to make modifications.

2021 is an excellent year to brush up on your passions, and home improvement is no exception. With a little innovation and dedication, you can quickly transform your house into a home. With the rapid advancement and growth of technology, smart homes have become irresistible.

Home improvement ideas have to embrace technology to keep up with the global home automation trend. Here are home improvement ideas you should contemplate.

1. Entertainment

Home entertainment and entertaining visitors will most likely be a spotlight of home improvement ideas for 2021. With entertainment outlets such as pubs, restaurants, and cinemas closed to the public, you could host get-togethers with loved ones in your own home.

1. Home Audio

Enjoy the sounds of a live music festival from the comfort of your home. Music lovers can savor music in their house or their backyard. You will need to contact a professional integrator to install a comprehensive distributed home audio system that includes both indoor and outdoor speakers.

It is worth noting that professional installers usually use in-wall and in-ceiling speakers for distributed audio. This will keep your home aesthetically appealing without disarraying your spaces with wireless speakers.

2. Wi-Fi

Almost every home entertainment system in this century is dependent on coherent, dependable Wi-Fi. If you live in a bigger house or if your internet connection is prone to irritating dead zones, it will greatly impair your streaming experience. The glaring solution is to upgrade your conventional router-based Wi-Fi to a mesh Wi-Fi system.

Since Advanced Network Assist technology is in-built, the mesh network is optimized in the background without the need for user intervention. Besides, with its family controls, mesh Wi-Fi allows you to monitor and manage your children’s Internet activity, which is a classy bonus.

2. Security

Home security has to be the epitome of home improvement ideas for 2021. A smart security system can do more than just alerting you whenever a burglar attempts to enter your home. It connects entry sensors and sirens to devices such as smart door locks, smart thermostats, and smart lighting through your Wi-Fi network.

These are the key features your smart home system can entail.

1. A Home Alarm Security System

Your first step in protecting your home will be to install a smart security system. Have a smart system to protect your entry points and inner levels of your home such as the hallway. Also have at least one smoke detector which can be in the kitchen or hallway. If you reside in an apartment complex, have at least a smoke detector on every level.

2. Smart Lighting

Additionally, lighting will deter intruders. Getting lights that are programmed to turn on and off at odd intervals each day will help to protect your house while you are away. Better yet, you can opt for security lights with surveillance cameras. As a result, anytime someone approaches your home, the camera lens will record a video of the person. This will assist you in either taking precautionary measures or later viewing the footage.

3. Cleaning Devices

We all know that a clean environment leads to healthier, happier, and more productive residents. Nevertheless, cleaning can be stressful at times. Most, if not all, of the work, can be done by a variety of tools and devices. Although some of them may require some initial configuration and getting used to, they will save you time and effort in the long run, and you will recognize the difference.

1. Robot Mop

Hard flooring, such as stone, hardwood, and tile requires mopping. A robot mop will penetrate the difficult-to-reach areas such as beneath shelves and around toilets and sinks, ensuring that every inch of your house is spotless.

Based on the type of pad you connect to it, the mop will automatically select the ideal cleansing method be it wet mopping, damp sweeping, or dry sweeping.

2. Toilet Bowl Cleaning System

Forget the days of routinely scrubbing your toilet. Contrary to bleach tablets dropped into the tank which can damage your septic system, the toilet bowl cleaning system directs a cleaning solution into the overflow tube of the flush valve, ensuring that no contaminants ever come into contact with the fill valve.

3. Automatic Carpet Cleaner

A carpet stains easily and is generally strenuous to clean. This mobile carpet cleaner is especially popular among pet owners for saving the day after an unexpected accident. With the push of a button, it instantly sprays, brushes, and suctions to eliminate all surface and set-in pet and tough stains.


Indeed, with the modern home increasingly becoming automated, you need to adopt the best home automation systems to monitor and control components of the home such as lighting, entertainment systems, and other devices.

PRINCE2 Project Management Terminology




Project management terminology is unique to the IT profession and consists in a rather complicated set of terms and phrases that are only now coming to the fore.  Although project management can be grouped together with the rest of the IT profession, for example in the management of project investment, project management refers to a particular type of activity in an organisation, usually distinct from the rest of the organisation.  

This characteristic was first brought to light through the study of activity theory used to describe the work of a group of specialists in the area of information systems.  An activity is an activity performed in the course of carrying out the activity goal. As outlined on a prince2 training online course.

As this activity is carried out, the activity goal is the result of the activity (the activity goal).  When an activity element is realized, the activity goal is the result of building up from past experience, usually made known as feedback to the activity element.

KnowledgeTree PRINCE2

An activity element may have a past consideration as an input, for example, the fact of a technical issue, the task completed, or a general understanding in the use of the deliverable.  This feedback is interpreted amongst the activity element and the activity goal is the accepted version.  Through this interpretation of feedback, the work of the activity element is the derivative of the principal idea of the activity goal.

The way the activity element is written is that of a pecul THAT accumulates over the whole of the life cycle of the project.  For each element, the activity goal is identified.  These project deliverables are then passed into the next available activity element to complete the task set out for the process.

The first use of project management terminology was by Martin Lazzarini and is followed today, by the Institute of Project Management in the UK (we can thank Tom Philips for this).  The project management body, the Institute of Project Management, has aiconic style of presentation which is still used today.  

This is somewhat Toyota style and reflects the way that concepts are brought to life.  I’ve known more than one individual from a company who has used this style of presentation and is seen as a good way to pass on some project ideas.

When I first learnt about this method, the acronym was developed by some people including?”, coaching some on how to do it better” and ” providing detailed, structured methods for its use”.  It was more speaking than writing and came about as a result of the work ofettes Palmer (ewaterfall) and David superficially (re Whereas a project is defined means that an infinite number of those are possible outcome).

PRINCE2 Project

The system developed by the Institute of Project Management was based on the activity of the first project manager called, “Projects – short work and actions”.  This was a method used to establish a method for the interpretation of input of project feedback, which lead to sentence, for people who saw no further option, to realise the role of project and manager (the project)  So the terms project management and project planning were born.

And all these terms are here to stay, because we’re always in some project or thinking whether that’s approaching a project or even developing skills to reach the next realisation.

Project management is the process of directing a designated group of people with defined activities to deal with or manage the project at a specific point in time and develop appropriate procedures to deliver successful outcomes in a bigger more comprehensive scheme.

Project planning is the process of determining the activities needed, along with any time a better approach would bring forward an effective total outcome (traffic) for the project.

Project management skills are those which are required for accomplishing the speech of use (THS).  It’s in the project plan that you specify all the activities and stipulate how they will bring into poor the project outcomes.

The project plan should predict exactly how to get to the end results expected.  The plan should also encompass these items.  The project plan and project put in detail is the purpose of selecting a project master and the Project board.  

The project plan will be used to provide a business case for funds, in funding processes, and as the basis of the implementation plan for everyone involved.
