I am very curious to know about the Biometric Service Features in Windows 7. Since I have recently started studying about the Biometric, I am eager to know that does Windows 7 supports that technology. Also frankly speaking I am not having much knowledge about it. So thought that guys hanging out there must be knowing about this technology. Please send some replies as early as possible along with detailed information about the biometric service.
For convenience, Windows 7 enables administrators and users to use fingerprint biometrics to log on equipment, lift privileges granted through the User Account Control (UAC) and perform basic management tasks devices fingerprint. Administrators can manage the fingerprint biometric devices in the configuration of Group Policy, enabling, limiting or blocking its use.
Windows 7 embraces Windows Biometric Framework, which outlines the fingerprint readers and additional biometric devices to higher-level applications in an identical manner, and provides a unswerving user experience to recognize and initiate fingerprint applications. To do so, offers the following:
- The biometric devices item in Control Panel, which permits users to direct the availability of biometric devices and if they can be used to login to a local computer or domain.
- Sustain for Device Manager to manage the biometric device drivers.
- Compatibility with the recommendation provider to facilitate and construct the use of biometrics to log on to a local computer and execute a UAC elevation.
- Configuring Group Policy to enable, immobilize or limit the use of biometric data to a local computer or domain. The configuration of Group Policy can also thwart the installation of driver software biometric devices or force their removal.
- Software biometric device driver obtainable from Windows Update.
To ensure that biometric identification systems are reliable, secure, interoperable and easy to use is a clear need to develop international standards. The government authorities in particular are unwilling to accept non-standard systems offered by a single manufacturer. It is necessary to reach a general agreement on the biometric characteristics to be measured and should extend the confidence that these measures make it possible to distinguish clearly between two different individuals. Standards are also needed to protect biometric data, both to maintain personal privacy and to prevent attacks that could lead to fraud and impersonation. The basic objectives of standardization are to facilitate the installation of biometric systems, lower its operation and increase their reliability of use.
Although the first biometric standards were created by governments and state security bodies in the 80 to exchange data on fingerprints, the current pace of development of standards did not begin until 2002. Currently, these standards are developing several national and international organizations from which you can include the International Organization for Standardization (ISO), International Electrotechnical Commission (IEC) and the Standardization Sector of ITU's Telecommunication (ITU-T). Industrial consortia also create standards that support the objectives of its members, while the specialized agencies of the United Nations, such as Civil Aviation Organisation (ICAO) and International Labour Organization (ILO), drafting standards in the within their specific domains may not have been addressed by other organizations. In particular, ICAO is responsible for standardization of travel documents machine-readable, including electronic passports, while the ILO has established guidelines for biometric identity documents for seafarers.
All biometric systems have a storage component that contains samples of biometric data of individuals linked to information about your identity. There is also a sensor that captures the biometric data of the individual. The captured data samples are compared with a reference template and a decision regarding its coincidence or not. Channels of communication between these components of a biometric system can be wired or wireless telecommunications, or private or public networks including the Internet. Whether the line is physical biometrics (eg DNA) and behavioral (eg, a keyboard sequence), each individual must have a unique feature. In addition, the biometric feature should remain unchanged over a certain period of time and must also be measurable.
The biometric features must not only be universal and unique, they also have to be reasonably permanent and easy to collect and measure. A biometric system should provide accurate results under different environmental circumstances and should be difficult to deceive. Perhaps the most important aspect of a biometric system is its acceptance by the general public. For obvious reasons, non-intrusive methods are more acceptable than intrusive techniques. Although DNA is considered the ultimate biometric parameter to identify a person (except identical twins), DNA testing is too intrusive for widespread use in the authentication of identity. The facial thermography, which detects head models created by the blood capillaries and issued by the skin, a method is not intrusive but is too expensive. Among the methods of biometrics currently considered for future development are blood drives, body odor, the composition of the skin, the layout of the nail bed, gait and ear shape. More research is needed to determine if any of these methods will eventually emerging as the choice of biometric techniques.
