Biometrics is, generally, the analysis of what can be measured of your biological features. When it comes to computer security, biometrics has to do with certification techniques that utilize differentiating physical features that can be automatically affirmed.
Biometrics has fast emerged as a new technique for identification and has already found practical applications in most hi-tech security fields. It is this particular aspect of the technique that we have selected to center on. We will try to identify how well biometrics can be applied to security and certification in various 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 authenticating different people, provides some unequaled rewards. Exclusively, biometric authentication provides an identification on an intrinsic character of a persons body. Soon to be relics, such as smart cards, magnetic stripe cards, normal keys, and so on, can be left at home or duplicated. Keywords can be forgotten or observed.
Fingerprint electronic scanners are the most normally applied biometric devices. They made there way into the mainstream several years ago, when producers started designing the technology into laptops and normal computer keyboards, along with providing stand-alone designs for a variety of security applications.
A persons prints remain the same throughout life. In over 140 years of print comparison worldwide, no two individuals prints have ever been encountered to be identical, not even those of identical twins. Good fingerprint readers have been put in PDAs like the iPaq Pocket PC, so the scanning technology is also unproblematic. Might not operate in industrial applications due to the fact that it needs clean hands to operate 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 summary, biometrics has become available to every individual at all different price ranges.

Chinese Lunar Calendar
Prior 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. Although people in China today use the Western calendar for almost all business, governmental and practical matters of daily life, the old method still serves as the basis for determining many seasonal holidays. This coexistence of two calendar schemes has long been accepted by the people of China.
However, this does not only apply to China, it also happens 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 complete its full cycle of 29 and a half days, a standard that makes the lunar year a whole 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 concur with the tropical year and its months coincide with the synodic months. It is not surprising that a few similarities exist between the Chinese and the Hebrew calendar.
For instance, an ordinary 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 determining what a Chinese year will be like, one needs to make a couple of astronomical calculations.
First of all, you have to determine 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 in 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 drop 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 differs from local custom in Third World countries.
The government wants to trade on the International markets, but the normal family in the country can not. So, the government adopted 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 example and no 7 o’clocks. They are also 543 years ahead of us, although this is more common, for example in Muslim countries.
