Biometrics applications: physical access This is the largest area of application of biometric technologies, and the most direct lineage to the feudal gate keeping system. Initially mainly used in military and other "high security" territories, physical access control by biometric technology is spreading into a much wider field of application. Biometric access control technologies are already being used in schools, supermarkets, hospitals and commercial centres, where the are used to manage the flow of personnel. Biometric technologies are also used to control access to political territory, as in immigration (airports, Mexico-USA border crossing). In this case, they can be coupled with camera surveillance systems and artificial intelligence in order to identify potential suspects at unmanned border crossings. Examples of such uses in remote video inspection systems can be found at A gate keeping system for airports relying on digital fingerprint and hand geometry is described at An electronic reconstruction of feudal gate keeping capable of singling out high-risk travellers from the rest is already applied at various border crossing points in the USA. "All enrolees are compared against national lookout databases on a daily basis to ensure that individuals remain low risk". As a side benefit, the economy of time generated by the inspection system has meant that "drug seizures ... have increased since Inspectors are able to spend more time evaluating higher risk vehicles". However, biometric access control can not only prevent people from gaining access on to a territory or building, they can also prevent them from getting out of buildings, as in the |

Face recognition In order to be able to recognize a person, one commonly looks at this persons face, for it is there where the visual features which distinguish one person from another are concentrated. Eyes in particular seem to tell a story not only about who somebody is, but also about how that persons feel, where his / her attention is directed, etc. People who do not want to show who they are or what is going on inside of them must mask themselves. Consequently, face recognition is a kind of electronic unmasking. "Real" face-to-face communication is a two-way process. Looking at somebody's face means exposing ones own face and allowing the other to look at oneself. It is a mutual process which is only suspended in extraordinary and voyeuristic situations. Looking at somebody without being looked at places the person who is visually exposed in a vulnerable position vis-à-vis the watcher. In face recognition this extraordinary situation is normal. Looking at the machine, you only see yourself looking at the machine. Face biometrics are extracted anonymously and painlessly by a mask without a face. Therefore the resistance against the mass appropriation of biometrical data through surveillance cameras is confronted with particular difficulties. The surveillance structure is largely invisible, it is not evident what the function of a particular camera is, nor whether it is connected to a face recognition system. In a protest action against the face recognition specialist According to |

Bandwidth The bandwidth of a transmitted communications signal is a measure of the range of frequencies the signal occupies. The term is also used in reference to the frequency-response characteristics of a communications receiving system. All transmitted signals, whether analog or digital, have a certain bandwidth. The same is true of receiving systems. Generally speaking, bandwidth is directly proportional to the amount of data transmitted or received per unit time. In a qualitative sense, bandwidth is proportional to the complexity of the data for a given level of system performance. For example, it takes more bandwidth to download a photograph in one second than it takes to download a page of text in one second. Large sound files, computer programs, and animated videos require still more bandwidth for acceptable system performance. Virtual reality (VR) and full-length three-dimensional audio/visual presentations require the most bandwidth of all. In digital systems, bandwidth is data speed in bits per second (bps).

WTO An international organization designed to supervise and liberalize world trade. The WTO (World Trade Organization) is the successor to the General Agreement on Tariffs and Trade (GATT), which was created in 1947 and liberalized the world's trade over the next five decades. The WTO came into being on Jan. 1, 1995, with 104 countries as its founding members. The WTO is charged with policing member countries' adherence to all prior GATT agreements, including those of the last major GATT trade conference, the Uruguay Round (1986-94), at whose conclusion GATT had formally gone out of existence. The WTO is also responsible for negotiating and implementing new trade agreements. The WTO is governed by a Ministerial Conference, which meets every two years; a General Council, which implements the conference's policy decisions and is responsible for day-to-day administration; and a director-general, who is appointed by the Ministerial Conference. The WTO's headquarters are in Geneva, Switzerland. |
