Authentication - What is Authentication

in /

What is Authentication?

Authentication is the process of identifying an individual, and is often the first step to providing access to a website, or a special page within that site.
How does it work?

Generally, authentication involves the individual providing the right username and password, sometimes in combination with answering a secret question with the right answer that only the user would know, or placing their fingertip on an authentication device that matches the fingerprint with one stored previously for the user.
Why is it useful?

Authentication is useful to ensure that only the right person is identified to have access to private and/or secure information.
What do you need to keep in mind about your child and authentication?

Because authentication is usually the first step to providing access to normally closed areas, it is important that your child understands to keep their usernames and passwords secret and not to share them, or yours, with anyone including friends.


Authentication can also refer to the process of registering software - entering authentication code to prove that you are the legitimate owner of the product. In most cases each code can only be in use on one (or perhaps more) computers.

Augmented Reality - What is Augmented Reality

What is Augmented Reality 


Augmented Reality (AR) takes information from the internet and overlays it on the real world. The things you look at can be 'augmented' with additional data such as text and images, or even animations, changing how we see the world and consume information.

How does it work?


To see augmented reality you need a digital camera to capture an image, and a screen on which to view it. This can be either a webcam connected to a PC, or a smartphone such as the Apple iPhone. When the camera or computer recognises a particular image (either because it sees a specific symbol or determines the user's location using GPS) this acts as a trigger to download the augmented information and display it over the top of the image on the device's screen.

Why is augmented reality useful?


Augmented reality can bring objects to life. For example, when using the technology to look at a building, augmented reality can overlay information on the building such as when it was built, who built it, what it is made from, and so on, just as might be done to a photo of that same building presented in a book. Similarly, when looking at a poster, augmented reality can be used to overlay an animated character. The combinations of augmented information overlayed on the real world are essentially limitless.


What do you need to keep in mind if your children are using augmented reality?


Augmented reality can be great fun, especially when the technology is used for purposes such as creating a virtual pop-up book. In terms of augmented reality information services, it is important to remind children that the information they receive is only as reliable as the service that has provided it.

Artificial Intelligence - what is Artificial Intelligence

What is Artificial Intelligence?


Artificial intelligence (AI) is a science that combines engineering with computer programming to create a machine that simulates how a human would think, respond or do something, such as a robot programmed to play chess, dance or carry on a conversation.

How does Artificial Intelligence work?


By studying how humans think, talk, sense and move, engineers and programmers collaborate to design machines that not only mimic human behaviour, but can also interact, learn, solve problems, and even express emotions and look like a person.

Why is it useful?


AI machines can do jobs that normally require the intelligence and problem solving abilities of a human, but are too dangerous, such as disabling bombs, working with hazardous materials and potentially even gathering research on far away planets.

What do you need to keep in mind about your child and artificial intelligence?


AI is an exciting area of computer science that also brings up ethical questions about what it means to be human, human relationships and interacting with human-like machines.
The AI community includes engineers, computer programmers, designers, speech specialists and psychologists, and is a growing field which could offer a challenging future career for your child.

Analog - What is Analog

What is Analog?

Analog is normally contrasted to 'digital'. It refers to the way we perceive the world through our senses. (The spelling 'analogue' is also used in British English.)

How does Analog work?

An analog version of something has an infinite gradation. For instance, the volume of a sound or the intensity of light. This degree of fineness can be approximated by converting the infinite range to a number of discrete steps. An old fashioned colour photograph is analog, but most photos today are digitised. However, within reason you can't tell the difference.

So why would you use a digital version of an analog source?

For two excellent reasons:
  1. It uses much less space to store and transmit
  2. It always stays the same, never degrading, despite the number of times it is copied.

What do you need to keep in mind about your child and analog?

Probably nothing. We live in a digital world now.
