Impact of emerging technologies
Artificial intelligence biometrics
A known problem about biometrics is that sometimes it falsely rejects a person's fingerprint
AI biometrics overcome this problem using dynamic profiling
The system learns by using AI about a person's fingerprint every time they scan it.
This way the user doesn't have to worry about putting their finger exactly in the right place to scan.
It learns from different alignments and therefore it can still match the fingerprintes stored on a database
Facial Recognition has the same problem as fingerprints
Facial-recognition systems confuses soft biometric changes like a beard, wearing glasses, etc
New systems use AI to learn from scanning a number of faces and pick out these soft biometric features
This means that the system can still recognise a face and cross-reference these attributes with the corresponding images stored on the database
Low-vision enhancement systems (LVES)
It uses video technology through a headset connected to a computer
This allows images to be projected inside the headset in front of the eyes
It amplifies infrared light and visible light so an image can be seen in darkness
The dim light is captured and passed through an image intensifier tube which converts the light into electrons
These electrons pass into another tube that produces several times the original number of electrons
A screen at the end of the tube is coated in phosphor dots that glow when electrons collide with them, which results in an image that is clearer than the original
Robotics are evolving quickly
An example of this is the use of drones,
They are unmanned flying devices that are used by militaries and civilians
Militaries use it for reconnaissance missions
Civilians use it for various things: surveying the landscape in 3D, investigating weather and search and rescue in natural disasters
All of these are under evaluation and we could see many applications evolve in the coming years
Another application is the use of robots in surgical procedures
It allows surgeons to perform complex procedures with more precision, flexibility and control than standard surgical techniques.
Surgeons have a robot with a camera arm and interactive mechanical arms that have joints like humans.
It's the science of making a message unintelligible to any unauthorised user
Also known as Encryption
There are a lot of methods of cryptography but they have a limited life as computers evolve at number crunching
Because of this, a hacker in the next few years is likely to decipher the encryption, unless computer designers strengthen their security
Quantum Cryptography works with the use of photons and their quantum properties to make an virtual unbreakable encryption
This protects the security of the data being transfered over fiber-optic cables.
Photons oscilate in various directions and produce random bits across the optical network.
Computer-assisted transaltion (CAT)
Language translators have a limited use
CAT is a type of language transaltor that uses specific software to help in the translation process
CAT uses 2 tools
Terminology databases: linguistic data bases that grow and learn from translations
Translation memories: automatically inserts known translations of certain words, phrases or sentences
3-D and holographic imaging
Holograpy is a technology that produces 3-D images
Involves the use of
A laser light
Interference of light
light intensity recording
It appears to move in the same way as the original, thus appearing in 3-D.
The hologram is produced by splitting a laser beam
The object beam is reflected to a photographic plate
The reference beam is reflected off a mirror and onto the same photographic plate
The holographic image is produced when the two beams meet at the photographic plate
Holographic computer memories
Is an artificial created by software
The technology is used in
