Although fingerprinting smacks of police techniques used long before the dawn of the information age, its digital successor finger scanning is the most widely used biometric technology. It relies on the fact that a fingerprint's uniqueness can be defined by analysing the so-called "minutiae" in somebody's fingerprint. Minutae include sweat pores, distance between ridges, bifurcations, etc. It is estimated that the likelihood of two individuals having the same fingerprint is less than one in a billion.
As an access control device, fingerprint scanning is particularly popular with military institutions, including the Pentagon, and military research facilities. Banks are also among the principal users of this technology, and there are efforts of major credit card companies such as Visa and MasterCard to incorporate this finger print recognition into the bank card environment.
Problems of inaccuracy resulting from oily, soiled or cracked skins, a major impediment in fingerprint technology, have recently been tackled by the development a contactless capturing device (
As in other biometric technologies, fingerprint recognition is an area where the "criminal justice" market meets the "security market", yet another indication of civilian spheres becomes indistinguishable from the military. The utopia of a prisonless society seems to come within the reach of a technology capable of undermining freedom by an upward spiral driven by identification needs and identification technologies.

German philosopher, mathematician, and political adviser, important both as a metaphysician and as a logician and distinguished also for his independent invention of the differential and integral calculus. 1661, he entered the University of Leipzig as a law student; there he came into contact with the thought of men who had revolutionized science and philosophy--men such as

It is a system, where letters get converted into numeric characters.
The numbers were not written down and sent but signaled with torches.
for example:
A=1-1
B=1-2
C=1-3
