An overview of BIOMETRICS

source - http://en.wikipedia.org/wiki/Biometrics

Before going into detail about biometrics, let us first understand – What is user authentication ?

User Authentication is the process of confirming an individual’s identity, either by verification or identification. This may be carried out by - 

  • A person recognising a person
  • Access control (PC, ATM, mobile phone)
  • Physical access control (house, building, area)
  • Identification (passport, driving licence)
Various user authentication methods
 
Token – “something that you have” such as smart card, magnetic card, key, passport, USB token
Knowledge – “something that you know” such as password, PIN
Biometrics – “something that you are” A physiological characteristic (such as fingerprint, iris pattern, form of hand) A behavioural characteristic (such as the way you sign, the way you speak)
 
Now, What is Biometrics ?

The term biometrics is derived from the Greek words bio (= life) and metric (= to measure). Biometrics is the measurement and statistical analysis of biological data. In IT, biometrics refers to technologies for measuring and analysing human body characteristics for authentication purposes.

Definition by Biometrics Consortium – 

Automatically recognising a person using distinguishing traits.

Biometrics Technologies 

  • Fingerprint biometrics – fingerprint recognition 
  • Eye biometrics – iris and retinal scanning
  • Face biometrics – face recognition using visible or infrared light (called facial thermography)
  • Hand geometry biometrics – also finger geometry
  • Signature biometrics – signature recognition
  • Voice biometrics – speaker recognition

Other Biometric Methods

Well, there are some more biometric methods which have basically been defined in the literature. These are :

  • Vein recognition (hand)
  • Palmprint
  • Gait recognition
  • Body odour measurements
  • Ear shape
  • DNA
  • Keystroke dynamics 
And these biometric methods have been futher classified into two areas – static and dynamic biometric methods.  Static (also called physiological) biometric methods – authentication based on a feature that is always present. And dynamic (also called behavioural) biometric methods – authentication based on a certain behaviour pattern.  Let us have a look at both these methods -

  Static biometric methodsFingerprint Recognition, Retinal scan, Iris scan, Hand geometry 

  Dynamic biometric methods – Signature Recognition, Speaker Recognition, Keystroke Dynamics
  
In the next section, we will be seeing – how biometrics works ?

Bluetooth GPS Data Logger

The Bluetooth GPS Data Logger is a unique, user friendly Wireless interface for vehicle tracking device. Bluetooth GPS Data Logger uses the Global Positioning System (GPS) to record vehicle movement, speed, route and duration of stops. This information can be displayed on a GIS mapping with MapInfo formatted while downloading data to PC. So user can view vehicle’s activity in precise detail.

Key Features -

  • Bluetooth GPS receiver and GPS data logger all in one
  • Optional Flash memory 4 MBytes
  • Data upload/download via mini USB
  • Motion sensor for auto power saving mode: the device switches on/off when it is moving/motionless. 
  • Power mode setting: GPS on only or bluetooth and GPS both on
  • Support Speaker Sound, LED indications
  • Ultra low power consumption, up to 22hours of continuous use with battery fully charged
  • Rechargeable 1100mA Li-ion battery with the original made-in-Japan battery cells
  • Cold/warm/hot start (42/38/3~6 seconds)
  • 16 channels “All-in-View” tracking.
  • Compatible with bluetooth enabled devices with Serial Port Profile (SPP)
  • High sensitivity: -152dbm
  • Build-in High Gain antenna
  • Data format: longitude, latitude, speed , UTC
  • GPS trace interval time setting from 1sec ~ 30 minutes
  • GPS Trace data by distance interval 2~65535 meters
