Biometrics is, generally, the subject of what can be measured of your biological features. As it pertains to computer security, biometrics has to do with authentication techniques that employ distinguishing physical features that can be mechanically substantiated.
Biometrics has fast emerged as a new technology for identification and has presently found practical applications in most hi-tech security fields. It is this particular aspect of the technique that we have selected to concentrate on. We seek to explain how easily biometrics can be utilized for security measures and authentication in assorted places.
A very large thought among the multitudes is that, Biometrics is available only for the rich and individuals with loads of cash. But that is a long way from reality. Biometrics other than being very efficient, is also very cost-efficient.
Utilizing biometrics for discovering and certifying human beings, offers some unequaled advantages. Exclusively, biometric authentication provides an identification on an intrinsic character of a persons body. Soon to be relics, similar to smart cards, magnetic stripe cards, physical keys, and so on, can be left at home or duplicated. Keywords can be shared or forgotten.
Finger print electronic scanners are the most widely utilized biometric devices. These devices moved into the mainstream a couple of years ago, when manufacturers began implanting the technology in laptops and regular computer keyboards, as well as offering stand-alone scanners for a wide range of security applications.
Fingerprints stay unaltered throughout an individuals life. In over 140 years of print comparison from all over the world, no two individuals prints have ever been noticed to be the same, not even the fingerprints of identical twins. Really good fingerprint scanners have been put in PDAs like the iPaq Pocket PC, so the reader technology is even easy. They may not function properly in industrial applications since it calls for clean hands to perform properly.
Lets take a look at voice biometrics. Comparable to face recognition, voice biometrics provides a way to verify a persons identity without the individuals knowledge. It is easier to take advantage of (by using a recording of a persons voice), it’s not possible to trick an analyst by faking another individuals voice.
In closing, biometrics has become available to all walks of life at all ranges of prices.

Chinese Lunar Calendar
January 16th, 2010Prior to their adoption of the Western solar calendar scheme, the Chinese almost wholly followed their own lunar calendar for determining the times of planting and harvesting and festival days. Though people in China today use the Western calendar for almost all business, governmental and practical matters of daily life, the old arrangement still serves as the basis for working out numerous seasonal holidays. This coexistence of two calendar systems has long been acknowledged by the people of China.
However, this does not only happen in China, it also occurs in most other Eastern countries, like Thailand, and most Arabic countries.
A lunar month is determined by measuring the period of time needed for the moon to finish its full cycle of 29 and a half days, a standard that makes the lunar year a full eleven days shorter than its solar counterpart. This difference is made up every 19 years by the addition of seven lunar months.
The 12 lunar months are further divided into 24 solar divisions distinguished by the four seasons and times of heat and cold, all of which bear a close relationship to the annual cycle of agricultural work.
The Chinese calendar – very much like the Hebrew calendar- is a combination of the solar and lunar calendars in that it strives to have its years coincide with the tropical year and its months agree with the synodic months. It is not surprising that a few similarities exist between the Chinese and the Hebrew calendar.
For instance, an average year has 12 months, a leap year has 13 months. An ordinary year has 353, 354, or 355 days, a leap year has 383, 384, or 385 days. When working out what a Chinese year will be like, one needs to make a number of astronomical calculations.
First of all, you have to work out the dates for the new moons. In these instances, a new Moon is the completely black Moon (that is to say, when the Moon is in conjunction with the Sun), not the first visible crescent, as is used by the Islamic and Hebrew calendars. The date of a new moon is then the first day of a new month.
The reason why the majority of countries which had their own calendars had to dump them in favour of the Western, Julian calendar that we use today, is business. First the British and then the Americans ran international business and they used the Gregorian calendar. Anyone who sought to work with them had to follow suit. This is why national policy often varies from local custom in Third World countries.
The government desires to deal on the International markets, but the ordinary family in the country can not. So, the government took up the Gregorian calendar but the people only pay lip service to it. I live in Thailand and people here do not even use the 24 hour day divided into two halves. Their day has four sections of six hours each and the first part starts at 6AM, not midnight. Therefore, they have four 4 o’clocks a day, for instance but no 7 o’clocks. They are also 543 years ahead of us, although this is more common, for instance in Muslim countries.
