Biometrics

 BIO=Pertaining to biology; MATRICS=Science and art of measurement.

o   The term 'biometrics' is used to refer to any and all of a variety of identification techniques which are based on some physical and difficult-to-alienate characteristic.

o   Today, the science of biometric technology refers to the "automated" methods used to recognize a person based upon physiological or behavioral characteristics.

o   Biometric technologies are becoming the foundation of an extensive array of highly secure identification and personal verification solutions.

 

  Biometrics is a modern technological field that focuses on identifying an individual through his or her unique physical traits.

Cyborg

In the years ahead we will witness machines with intelligence more powerful than that of humans. This will mean that robots, not humans, make all the important decisions. It will be a robot-dominated world with dire consequences for humankind. Is there an alternative way ahead?

Humans have limited capabilities. Humans sense the world in a restricted way, vision being the best of the senses. Humans understand the world in only 3 dimensions and communicate in a very slow, serial fashion called speech. But can this be improved on? Can we use technology to upgrade humans?

CD Burning Technology

                                                             CD Basics: The Bumps

  CDs store music and other files in digital form –that is, the information on the disc is represented by a series of 1s and 0s. In conventional CDs, these 1s and 0s are represented by millions of tiny bumps and flat areas on the disc's reflective surface. The bumps and flats are arranged in a continuous track that measures about 0.5 microns (millionths of a meter) across and 3.5 miles (5 km) long.

A CD has a long, spiraled data track. If you were to unwind this track, it would extend out 3.5 miles (5 km).

To read this information, the CD drive passes a laser beam over the track. When the laser passes over a flat area in the track, the beam is reflected directly to an optical sensor on the laser assembly. The CD drive interprets this as a 1. When the beam passes over a bump, the light is bounced away from the optical sensor. The CD drive recognizes this as a 0.

 

Artificial Neural Network

Ever since eternity, one thing that has made human beings stand apart from the rest of the animal kingdom is, its brain .The most intelligent device on earth, the “Human brain” is the driving force that has given us the ever-progressive species diving into technology and development as each day progresses.

3D PASSWORD

Users nowadays are provided with major password stereotypes such as textual passwords, biometric scanning, tokens or cards (such as an ATM) etc. Current authentication systems suffer from many weaknesses.

Textual passwords are commonly used; however, users do not follow their requirements. Users tend to choose meaningful words from dictionary or their pet names, girlfriends etc. Ten years back Klein performed such tests and he could crack 10-15 passwords per day. On the other hand, if a password is hard to guess, then it is often hard to remember. Users have difficulty remembering a password that is long and random appearing. So, they create short, simple, and insecure passwords that are susceptible to attack. Which make textual passwords easy to break and vulnerable to dictionary or brute force attacks. Graphical passwords schemes have been proposed. The strength of graphical passwords comes from the fact that users can recall and recognize pictures more than words.

What is Bluetooth?

What is it - a technology, a standard, an initiative, or a product?

 Bluetooth wireless technology is a de facto standard, as well as a specification for small form factor, low-cost, short range radio links between mobile PCs, mobile phones and other portable devices. The Bluetooth Special Interest Group is an industry group consisting of leaders in the telecommunications, computing, and networking industries that are driving development of the technology and bringing it to market.

ANDROID OS

The BlackBerry and iPhone, which have appealing and high-volume mobile platforms, are addressing opposite ends of a spectrum. The BlackBerry is rock-solid for the enterprise business user. For a consumer device, it's hard to compete with the iPhone for ease of use and the "cool factor." Android, a young and yet-unproven platform, has the potential to play at both ends of the mobile-phone spectrum and perhaps even bridge the gulf between work and play.
