Passports

Passport

A passport is a document, issued by a national government, which certifies the identity and nationality of its holder for the purpose of international travel. The elements of identity contained in all standardized passports include information about the holder, including name, date of birth, gender and place of birth.

Epassport

A biometric passport, also known as an e-passport, ePassport, is a combined paper and electronic passport that contains biometric information that can be used to authenticate the identity of travellers. It uses contactless smart card technology, including a microprocessor chip embedded in the front or back cove of the passport. Document and chip characteristics are documented in the International Civil Aviation Organization's. The passport's critical information is both printed on the data page of the passport and stored in the chip. Public Key Infrastructure  is used to authenticate the data stored electronically in the passport chip making it expensive and difficult to forge when all security mechanisms are fully and correctly implemented. The chip contains all the information’s on page 2 of a passport, except signature, and the passport should be open on page 2 to read the chip this acts as a lock and more secure way to protect or personal information.

Difference

A normal passport does not have a microchip, an E-passport contains a RFIC chip which can be read without actually needing to look into the document. The ePassport's chip is of the type "Write-Once, Read-Many" that is sometimes stated using the ugly WORM acronym. Once personalized with the passport holder's data, the content of chip cannot be changed.

GPS and Satellite

With these devices the whole world is a town you know!!

GPS:-

The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.The system provides critical capabilities to military, civil and commercial users around the world. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver.

 

Satellite navigation system:- 

Satellite navigation is a system of satellites that provide autonomous geo-spatial positioning with global coverage. It allows small electronic receivers to determine their location (longitude, latitude, and altitude) to high precision (within a few meters) using time signals transmitted along a line-of-sight by radio from satellites. The signals also allow the electronic receivers to calculate the current local time to high precision, which allows time synchronization. 

Biometric

Biometric:

Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals. Biometric identifiers are often categorized as physiological versus behavioral characteristics.

 Physiological characteristics are related to the shape of the body. Examples are fingerprint, face recognition, DNA, Palm print, hand geometry, iris recognition, retina and scent.

Behavioral characteristics are related to the pattern of behavior of a person, such as:  typing rhythm, gait, and voice.

Iris recognition:

Iris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on video images of the irides of an individual's eyes, whose complex random patterns are unique and can be seen from some distance.

Finger print recognition:

Fingerprint recognition or fingerprint authentication refers to the automated method of verifying a match between two human fingerprints. Fingerprints are one of many forms of biometrics.

Voice recognition:

Speaker recognition is the identification of the person who is speaking by characteristics of their voices (voice biometrics), also called voice recognition. There is a difference between speaker recognition (recognizing who is speaking) and speech recognition (recognizing what is being said). These two terms are frequently confused, and "voice recognition" can be used for both.

portable entertainment devices

portable entertainment devices such as : mp3 or DVD-player, which allow people to listen to music or films are now common place. what do you think are the main advantages and disadvantages of this development?

  
Our lives is surrounded with devises that wont make you say the word "bored" again.
It ranges from portable devices so small that can be carried anywhere inside once pocket !! and devices so big, like plasma TV...... TV, which would give you the feeling of being in a cinema !! 
Everything has advantages and disadvantages, like a blade that has two edge it depends on which edge you use and for what. 
Portable devices are wonderful devices not only for entertainment but also for work and our daily life needs such as Iphone. We can use it for fun by downloading games and listening to music and so on, we can also use it for daily requirements such us using notes or calculator.  
These devices can also be very dangerous especially  for children if not watched.  Teenagers can easily become addicted to theses devices, and might not focus on their studies.

So these devices are such amazing inventions but be careful on how you use them !!..
